1. Field of the Invention
The present invention relates to techniques for supporting presentation of multi-path and multi-source viewing content.
2. Background Art
Images may be generated for display in various forms. For instance, television (TV) is a widely used telecommunication medium for transmitting and displaying images in monochromatic (“black and white”) or color form. Conventionally, images are provided in analog form and are displayed by display devices in two dimensions. More recently, images are being provided in digital form for display in two dimensions on display devices having improved resolution (e.g., “high definition” or “HD”). Even more recently, images capable of being displayed in three dimensions are being generated.
Conventional displays may use a variety of techniques to achieve three-dimensional (3D) image viewing functionality. For example, various types of glasses have been developed that may be worn by users to view three-dimensional images displayed by a conventional display. Examples of such glasses include glasses that utilize color filters or polarized filters. In each case, the lenses of the glasses pass two-dimensional (2D) images of differing perspective to the user's left and right eyes. The images are combined in the visual center of the brain of the user to be perceived as a three-dimensional image. In another example, synchronized left eye, right eye liquid crystal display (LCD) shutter glasses may be used with conventional two-dimensional image displays to create a three-dimensional viewing illusion. In still another example, LCD display glasses are being used to display three-dimensional images to a user. The lenses of the LCD display glasses include corresponding displays that provide images of differing perspective to the user's eyes, to be perceived by the user as three-dimensional.
Problems exist with such techniques for viewing three-dimensional images. For instance, persons that use such displays and systems to view three-dimensional images may suffer from headaches, eyestrain, and/or nausea after long exposure. Furthermore, some content, such as two-dimensional text, may be more difficult to read and interpret when displayed three-dimensionally. To address these problems, some manufacturers have created display devices that may be toggled between three-dimensional viewing and two-dimensional viewing. A display device of this type may be switched to a three-dimensional mode for viewing of three-dimensional images, and may be switched to a two-dimensional mode for viewing of two-dimensional images (and/or to provide a respite from the viewing of three-dimensional images).
A parallax barrier is another example of a device that enables images to be displayed in three-dimensions. A parallax barrier includes a layer of material with a series of precision slits. The parallax barrier is placed proximal to a display so that each of a user's eyes sees a different set of pixels to create a sense of depth through parallax. A disadvantage of parallax barriers is that the viewer must be positioned in a well-defined location in order to experience the three-dimensional effect. If the viewer moves his/her eyes away from this “sweet spot,” image flipping and/or exacerbation of the eyestrain, headaches and nausea that may be associated with prolonged three-dimensional image viewing may result. Conventional three-dimensional displays that utilize parallax barriers are also constrained in that the displays must be entirely in a two-dimensional image mode or a three-dimensional image mode at any time.
Some conventional devices are capable of receiving portions of 2D content from different sources to be presented on a single screen. Other conventional devices are capable of receiving media guide text and program channels of media content wherein a remote control is used to produce guide text overlaying the media content on a single 2D screen. Similarly, a conventional browser may receive 2D graphic and textual content from many sources (e.g., different servers) and construct a single display within a single window. Yet other conventional devices are capable of receiving full 3D2 content from a single source. For example, such full 3D2 content may be downloaded from a server or retrieved from a removable or fixed storage. The single piece of 3D2 content can have a first portion that is destined for the left eye of a viewer and a second portion that is destined for the right eye of the viewer. These portions represent perspectives (a.k.a. camera views) of a common video event.
BRIEF SUMMARY OF THE INVENTIONMethods, systems, and apparatuses are described for supporting presentation of multi-path and multi-source viewing content as shown in and/or described herein in connection with at least one of the figures, as set forth more completely in the claims.
The accompanying drawings, which are incorporated herein and form a part of the specification, illustrate the present invention and, together with the description, further serve to explain the principles of the invention and to enable a person skilled in the pertinent art to make and use the invention.
The present invention will now be described with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements. Additionally, the left-most digit(s) of a reference number identifies the drawing in which the reference number first appears.
DETAILED DESCRIPTION OF THE INVENTION I. IntroductionThe present specification discloses one or more embodiments that incorporate the features of the invention. The disclosed embodiment(s) merely exemplify the invention. The scope of the invention is not limited to the disclosed embodiment(s). The invention is defined by the claims appended hereto.
References in the specification to “one embodiment,” “an embodiment,” “an example embodiment,” etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to effect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.
Furthermore, it should be understood that spatial descriptions (e.g., “above,” “below,” “up,” “left,” “right,” “down,” “top,” “bottom,” “vertical,” “horizontal,” etc.) used herein are for purposes of illustration only, and that practical implementations of the structures described herein can be spatially arranged in any orientation or manner.
Embodiments described herein provide systems and methods for supporting presentation of multi-path and multi-source viewing content. For instance, the viewing content may include multiple portions that originate from respective sources and that are received via respective paths. Each of the portions may include two-dimensional (2D) content or three-dimensional (3D) content. Two-dimensional (2D) content is content that is configured to be perceived as one or more two-dimensional images. For instance, the two-dimensional content may represent a single perspective of a video event. Three-dimensional (3D) content is content that is configured to be perceived as one or more three-dimensional images. For example, the three-dimensional content may represent multiple perspectives of a video event.
The viewing content may be displayed to a user among any number (e.g., 1, 2, 3, etc.) of regions of a screen, such as a fixed 2D screen, a fixed 3D screen, or an adaptable 3D screen. With respect to an adaptable 3D screen, the viewing content may be displayed among the regions by driving an adaptable light manipulator and/or a pixel array in a coordinated fashion. Some exemplary techniques for driving an adaptable light manipulator and/or a pixel array in a coordinated fashion are described in commonly-owned co-pending U.S. patent application Ser. No. ______, filed on even date herewith and entitled “Coordinated Driving of Adaptable Light Manipulator, Backlighting and Pixel Array in Support of Adaptable 2D and 3D Displays,” the entirety of which is incorporated by reference herein.
The adaptable light manipulator may comprise, for example, an adaptable lenticular lens such as that described in commonly-owned, co-pending U.S. patent application Ser. No. 12/774,307, filed on May 5, 2010, and entitled “Display with Elastic Light Manipulator,” the entirety of which is incorporated by reference herein, or an adaptable parallax barrier such as that described in commonly-owned co-pending U.S. patent application Ser. No. 12/845,440, filed on Jul. 28, 2010, and entitled “Adaptable Parallax Barrier Supporting Mixed 2D and Stereoscopic 3D Display Regions,” the entirety of which is incorporated by reference herein. As described in those applications, the adaptable light manipulator can be dynamically modified in order to accommodate, for example, a changing viewer sweet spot or switching between two-dimensional images and three-dimensional images. As further described in commonly-owned, co-pending U.S. patent application Ser. No. 12/774,225, filed on May 5, 2010 and entitled “Controlling a Pixel Array to Support an Adaptable Light Manipulator,” the entirety of which is incorporated by reference herein, the manner in which images are rendered to pixels of a pixel array used in conjunction with such an adaptable light manipulator may be coordinated with the state of the adaptable light manipulator to support a variety of viewing configurations.
Moreover, an adaptable light manipulator, a pixel array and a non-uniform light generator may be driven in a coordinated fashion. As described in the aforementioned, incorporated U.S. patent application Ser. No. 12/845,440, in a case of where the adaptable light manipulator is an adaptable parallax barrier, simultaneous presentation of two-dimensional and three-dimensional content (and/or various instances of three-dimensional content representing differing numbers of perspectives) via different regions of the same display is also enabled. This feature may be supported by a non-uniform light generator (such as a backlighting array) as described in commonly-owned, co-pending U.S. patent application Ser. No. ______, filed on even date herewith and entitled “Backlighting Array Supporting Adaptable Parallax Barrier”, the entirety of which is incorporated by reference herein.
II. Exemplary Display Systems that Support Multiple Viewing ConfigurationsEach fixed 2D screen 167, fixed 3D screen 169, and adaptable light manipulating 2D/3Dx screen 171 is capable of supporting presentation of 3D portions 161A-161N of 3D content in respective regions of a screen surface. Regions of each screen 167, 169, and 171 are configured to support presentation of the respective 3D portions 161A-161N in the respective regions of the screen surface. The configurations of the various regions of an adaptable light manipulating 2D/3Dx screen 171 may be different or the same. Some examples of an adaptable light manipulating 2D/3Dx screen are described in detail below with reference to FIGS. 1C and 2-20.
External sources 194A-194N are configured to provide the respective 3D portions 161A-161N of the 3D content to media node 160. External sources 194A-194N are also configured to provide respective offer contents 163A-163N to media node 160. Each of the offer contents 163A-163N includes an offer that relates to at least one 3D portion of the 3D content. For example, first external source 194A may provide a first 3D portion 161A to media node 160. First external source 194A may also provide first offer content 163A to media node 160 that relates to an Nth 3D portion 161N. If the offer from first external source 194A is accepted by a user, Nth external source 194N may provide the Nth 3D portion 161N to media node 160. Nth external source 194N may also provide Nth offer content 163N to media node 160 that relates to another 3D portion that may be provided by another of the external sources 194A-194N, and so on.
In another example, first external source 194A may provide the first 3D portion 161A to media node 160. Upon determining that the first 3D portion 161A is provided to media node 160, Nth external source 194N may provide Nth offer content 163N to media node 160 that relates to the Nth 3D portion 161N. If the offer from Nth external source 194N is accepted by the user, Nth external source 194N may provide the Nth 3D portion 161N to media node 160. Upon determining that the Nth 3D portion 161N is provided to media node 160, another of the external sources 194A-194N may provide its offer content to media node 160 that relates to a respective 3D portion of the 3D content, and so on.
External sources 194A-194N include circuitry 165A-165N for managing accounts, billing, licenses, and transactions pertaining to the 3D portions 161A-161N. For example, if first external source 194A provides first 3D portion 161A to media node 160, circuitry 165A may indicate that the first 3D portion 161A has been provided to media node 160 in an account of the user of media node 160. Circuitry 165A may perform operations to bill the user for provision of the first 3D portion 161A, verify that the user is within a group that is authorized (e.g., licensed) to receive the first 3D portion, etc.
Media node 160 includes processing circuitry 162, storage 176, a screen assembly 178, media source interface(s) circuitry 180, and screen interface(s) circuitry 192. Media source interface(s) circuitry 180 receives the 3D portions 161A-161N of the 3D content from the respective external sources 194A-194N for processing by processing circuitry 162. Storage 176 queues the 3D portions 161A-161N as needed so that the portions 161A-161N may be synchronized for presentation. Storage 176 may include one or more internal sources that provide respective portions of the 3D content. For instance, an internal source may include fixed or removable media storage from which one or more of the 3D portions 161A-161N may be retrieved. Screen assembly 178 is configured to present the 3D content (e.g., simultaneously present the 3D portions 161A-161N) once the 3D portions 161A-161N are synchronized. Screen assembly 178 may be a fixed 2D screen assembly, a fixed 3D screen assembly, or an adaptable light manipulating 2D/3Dx screen assembly.
Processing circuitry 162 includes circuitry 164, 166, 168, 170, 172, and 174 and 3D portion(s) adjustments circuitry 182. Circuitry 164 selects the first 3D portion 161A of the 3D content from first external source 194A. Circuitry 166 interacts with a second source (e.g., second external source 194B) to locate a second portion and offer based on the first 3D portion 161A. Circuitry 168 supports billing and account management regarding the various 3D portions 161A-161N. For instance, circuitry 168 may communicate with any one or more of external sources 194A-194N to facilitate proper billing and account updates regarding the respective 3D portions 161A-161N.
Circuitry 170 supports operations pertaining to acceptance or rejection of each offer that is received by media node 160. For instance, circuitry 170 may inform external sources 194A-194N whether offers that are received therefrom are accepted or rejected. Circuitry 172 initiates delivery of the second 3D portion from the second source in response to location of the second 3D portion by circuitry 166. Circuitry 174 manages delivery of the 3D portions 161A-161N. For instance, circuitry 174 may communicate with circuitry 172 to authorize initiation of delivery of the second portion by circuitry 172. Circuitry 174 also supports queuing of the 3D portions 161A-161N. For example, circuitry 174 may determine an amount of storage 176 to be allocated for queuing of the 3D portions 161A-161N. In accordance with this example, circuitry 174 may monitor an amount of storage 176 that is utilized to determine the amount of storage 176 to be allocated.
3D portion(s) adjustments circuitry 182 performs operations on the 3D portions 161A-161N to facilitate presentation of the 3D content. 3D portion(s) adjustments circuitry 182 includes circuitry 184, 186, 188, and 190. Circuitry 184 is configured to decode and/or decrypt the 3D portions 161A-161N that are received from respective external sources 194A-194N, so that processing may be performed on the 3D portions 161A-161N. For instance, such processing may be performed by circuitry 186, 188, and/or 190, which are described below. Circuitry 184 is also configured to encrypt and/or encode the 3D content, including the 3D portions 161A-161N, before the 3D content is delivered to external device(s) 196.
Circuitry 186 synchronizes frames of the 3D portions 161A-161N. For example, circuitry 186 may apply time offsets to one or more of the portions 161A-161N and/or adjust the frame rates of one or more of the 3D portions 161A-161N in order to facilitate synchronization of the 3D portions 161A-161N. In accordance with this example, circuitry 186 may increase the frames rates of one or more of the 3D portions 161A-161N, decrease the frame rates of one or more of the 3D portions 161A-161N, increase the frame rates of some of the 3D portions 161A-161N while decreasing the frame rates of others of the 3D portions 161A-161N, etc.
Circuitry 188 is configured to integrate the 3D portions 161A-161N into a single stream or file. Circuitry 190 is configured to resize the regions that are associated with the respective 3D portions 161A-161N based on any of a variety reasons, including but not limited to bandwidth limitations, user input, etc. Circuitry 190 may reduce the size of region(s) that are associated with one or more (e.g., all) of the 3D portions 161A-161N, increase the size of region(s) that are associated with one or more (e.g., all) of the 3D portions 161A-161N, or reduce the size of some regions which correspond to a first subset of the 3D portions 161A-161N while increasing the size of other regions which correspond to a second subset of the 3D portions 161A-161N. Circuitry 190 may reduce the resolution of one or more of the 3D portions 161A-161N, increase the resolution of one or more of the 3D portions 161A-161N, remove overlapping content from one or more of the 3D portions 161A-161N, crop one or more of the 3D portions 161A-161N (e.g., to fit a screen characteristic such as 3:4, 9:16, or windowing), etc. For instance, circuitry 190 may perform such operations based on resizing of the corresponding regions.
Screen interface(s) circuitry 192 provides the 3D content, including the 3D portions 161A-161N, to external device(s) 196 for presentation. Screen interface(s) circuitry 192 may provide the 3D portions 161A-161N in any suitable number of streams. For instance, screen interface(s) circuitry 192 may provide the 3D portions 161A-161N in respective streams or in a single combined stream to external device(s) 196.
For purposes of illustration, assume that a first portion comprising a desired video presentation is selected from an internal or external “first” source. This first portion may yield the presentation in 2D, for example, or 3D2. Either in response to a user's further search or “add” request (perhaps via a keypad or external remote control not shown, and at any time before or during the presentation of the first portion) or automatically based on the initial selection of the first portion, processing circuitry 160 assists or carries out location of a second portion of content related to the first portion. The internal or external location of the second portion is at a different source than that of the first portion.
An automatically identified second portion could be (but doesn't have to be) offered for possible rejection by the viewer. If accepted or if settings do not require the viewer's confirmation, processing work may be performed. For example, the second source portion may or may not have many differing characteristics from that of the first portion. Processing circuitry 160 may need to operate on at least one if not both of the portions to eliminate the differences. Processing circuitry 160 may synchronize, as well. For example, the first portion may be one-third of the way into the presentation, and the second portion may need an offset and synchronization. The output of processing circuitry 160 may be two independent files or streams or one combined stream. Such output may need to feed one or more fixed 2D, fixed 3D, and adaptive light manipulating internal or external screen assemblies. Processing circuitry 160 needs to make all of these things happen when needed, or provide support therefor. Other functionality of processing circuitry 160 can be appreciated with reference to the labels in the
External sources 131A-131N are configured to provide respective contents 135A-135N to media node 101. The contents 135A-135N may be fully independent and unrelated, or fully or partially related. External sources 131A-131N are also configured to provide respective offer contents 137A-137N to media node 101. Each of the offer contents 137A-137N includes an offer that relates to at least one of the contents 135A-135N. For example, first external source 131A may provide first content 135A to media node 101. First external source 131A may also provide first offer content 137A to media node 101 that relates to Nth content 135N. If the offer from first external source 131A is accepted by a user, Nth external source 131N may provide the Nth content 135N to media node 101. Nth external source 131N may also provide Nth offer content 137N to media node 101 that relates to other content that may be provided by another of the external sources 131A-131N, and so on.
In another example, first external source 131A may provide the first content 135A to media node 101. Upon determining that the first content 135A is provided to media node 101, Nth external source 131N may provide Nth offer content 137N to media node 101 that relates to the Nth content 135N. If the offer from Nth external source 131N is accepted by the user, Nth external source 131N may provide the Nth content 135N to media node 101. Upon determining that the Nth content 135N is provided to media node 101, another of the external sources 131A-131N may provide its offer content to media node 101 that relates to other content, and so on.
External sources 131A-131N include circuitry 139A-139N for managing accounts, billing, licenses, and transactions pertaining to the contents 135A-135N. For example, if first external source 131A provides first content 135A to media node 101, circuitry 139A may indicate that the first content 135A has been provided to media node 101 in an account of the user of media node 101. Circuitry 139A may perform operations to bill the user for provision of the first content 135A, verify that the user is within a group that is authorized (e.g., licensed) to receive the first content, etc.
Media node 101 includes processing circuitry 103, storage 115, at least one adaptable light manipulating 2D/3Dx screen assembly 117, media source interface(s) circuitry 119, and screen interface(s) circuitry 129. Media source interface(s) circuitry 119 receives the contents 135A-135N from the respective external sources 131A-131N for processing by processing circuitry 103. Storage 115 queues the contents 135A-135N as needed so that the contents 135A-135N may be synchronized for presentation. Storage 115 may include one or more internal sources, each of which is capable of providing respective content. For instance, an internal source may include fixed or removable media storage from which one or more of the contents 135A-135N may be retrieved. The at least one screen assembly 117 is configured to simultaneously present the contents 135A-135N once the contents 135A-135N are synchronized.
Processing circuitry 103 includes circuitry 105, 107, 109, 111, and 113 and content adjustments circuitry 121. Circuitry 105 provides software application (e.g., browser) based support for selection of the various contents 135A-135N. For instance, circuitry 105 may generate a graphical interface for enabling the viewer to select one or more of the contents 135A-135N for presentation. Circuitry 107 supports billing and account management regarding the various contents 135A-135N. For instance, circuitry 107 may communicate with any one or more of external sources 131A-131N to facilitate proper billing and account updates regarding the respective contents 135A-135N.
Circuitry 109 provides viewer interface support for enabling the viewer to accept or reject each offer that is received by media node 101. For instance, circuitry 109 may inform external sources 131A-131N whether offers that are received therefrom are accepted or rejected. Circuitry 111 manages delivery of the contents 135A-135N. For instance, circuitry 111 may delay delivery of the various contents 135A-135N until the contents 135A-135N are synchronized. Circuitry 111 also supports queuing of the contents 135A-135N. For example, circuitry 111 may determine an amount of storage 115 to be allocated for queuing of the contents 135A-135N. In accordance with this example, circuitry 111 may monitor an amount of storage 115 that is utilized to determine the amount of storage 115 to be allocated.
Circuitry 113 supports full and regional (re)configuration of adaptable light manipulating 2D/3Dx screen assemblies. For instance, circuitry 113 may provide screen (re)configuration commands for configuring an entire adaptable light manipulating 2D/3Dx screen assembly or one or more regions thereof based on any of a factors, including but not limited to bandwidth limitations, user input, etc. In one example, such screen (re)configuration commands may be integrated into the one or more streams/files that are delivered toward the screen assembly. In another example, such screen (re)configuration commands may be sent externally from the aforementioned one or more streams/files via separate command signaling using the same communication pathway or a separate pathway that is independent from the pathway that is used for delivering the one or more streams/files.
Content adjustments circuitry 121 performs operations on the contents 135A-135N to facilitate presentation thereof. Content adjustments circuitry 121 includes circuitry 123, 125, and 127. Circuitry 123 is configured to decode and/or decrypt the contents 135A-135N that are received from respective external sources 131A-131N, so that processing may be performed on the contents 135A-135N. For instance, such processing may be performed by circuitry 125 and/or 127, which are described below. Circuitry 123 is also configured to encrypt and/or encode the contents 135A-135N before delivery thereof to external device(s) 196.
Circuitry 125 supports outputting multiple streams or files or an integrated stream or file. For example, circuitry 125 may synchronize frames of the contents 135A-135N by applying time offsets to one or more of the contents 135A-135N and/or by adjusting the frame rates of one or more of the contents 135A-135N. In accordance with this example, circuitry 125 may increase the frames rates of one or more of the contents 135A-135N, decrease the frame rates of one or more of the contents 135A-135N, increase the frame rates of some of the contents 135A-135N while decreasing the frame rates of others of the contents 135A-135N, etc.
Circuitry 127 is configured to resize the regions that are associated with the contents 135A-135N based on any of a variety reasons, including but not limited to bandwidth limitations, user input, etc. Circuitry 127 may reduce the size of region(s) that are associated with one or more of the contents 135A-135N, increase the size of region(s) that are associated with one or more of the contents 135A-135N, or reduce the size of some regions which correspond to a first subset of the contents 135A-135N while increasing the size of other regions which correspond to a second subset of the contents 135A-135N. Circuitry 190 may reduce the resolution of one or more of the contents 135A-135N, increase the resolution of one or more of the contents 135A-135N, remove overlapping content from one or more of the contents 135A-135N, change (e.g., increase or decrease) a frame rate that is associated with one or more of the contents 135A-135N, crop one or more of the contents 135A-135N, etc. For instance, circuitry 127 may perform such operations based on resizing of the corresponding regions.
Screen interface(s) circuitry 129 provides the various contents 135A-135N to external device(s) 133 for presentation. Screen interface(s) circuitry 129 may provide the contents 135A-135N in any suitable number of streams. For instance, screen interface(s) circuitry 129 may provide the contents 135A-135N in respective streams or in a single combined stream to external device(s) 133. Screen interface(s) circuitry 129 provides the screen configuration commands that specify how the regions of each adaptable light manipulating 2D/3Dx assembly of the external device(s) 133 is to be configured to support the presentation of the multiple instances of content. The screen configuration commands may be integrated among the contents 135A-135N or separate from the contents 135A-135N.

The remainder of this section describes some exemplary display systems that include display elements, such as an adaptable light manipulator, a non-uniform light generator, and a pixel array, to enable multiple two-dimensional (2D) and three-dimensional (3D) viewing configurations. A two-dimensional configuration is used to display a 2D representation of video content. A three-dimensional configuration is used to display a 3D representation of video content. A three-dimensional configuration may include any two or more viewpoints (a.k.a. perspectives), two of which may be combined to provide a three-dimensional viewing experience. For instance, a three-dimensional configuration that includes n viewpoints is said to be a 3Dn configuration, where n is a positive integer greater than or equal to two. The configurations that are used to display the different video contents or portions thereof may be different or the same. Moreover, different video contents may be fully unrelated or at least partially related. For example, first content may be at least partially related to second content if the second content is 2D or 3D content and the first content includes movie text (e.g., closed caption text) that relates to the 2D or 3D content.
A. Example Display Systems Using Adaptable Parallax Barriers
Pixel array 122 comprises a two-dimensional array of pixels (e.g., arranged as a grid or other distribution). Pixel array 122 is a self-illuminating or light-generating pixel array such that the pixels of pixel array 122 each emit light included in light 132. Each pixel may be a separately addressable light source (e.g., a pixel of a plasma display, an LCD display, an LED display such as an OLED display, or of other type of display). Each pixel of pixel array 122 may be individually controllable to vary color and intensity. In an embodiment, each pixel of pixel array 122 may include a plurality of sub-pixels that correspond to separate color channels, such as a trio of red, green, and blue sub-pixels included in each pixel.
Adaptable parallax barrier 124 is positioned proximate to a surface of pixel array 122. Barrier element array 142 is a layer of adaptable parallax barrier 124 that includes a plurality of barrier elements or blocking regions arranged in an array. Each barrier element of the array is configured to be selectively opaque or transparent. Combinations of barrier elements may be configured to be selectively opaque or transparent to enable various effects. For example, the states of the barrier elements of barrier element array 142 may be configured such that light 132 emanating from pixel array 122 is filtered to produce filtered light 134, wherein filtered light 134 includes one or more two-dimensional and/or three-dimensional images that may be viewed by users 136 in a viewing space 106.
Depending upon the implementation, each barrier element may have a round, square, or rectangular shape, and barrier element array 142 may have any number of rows of barrier elements that extend a vertical length of barrier element array 142. In another embodiment, each barrier element may have a “band” shape that extends a vertical length of barrier element array 142, such that barrier element array 142 includes a single horizontal row of barrier elements. Each barrier element may include one or more of such bands, and different regions of barrier element array 142 may include barrier elements that include different numbers of such bands.
It is noted that in some embodiments, barrier elements may be capable of being completely transparent or opaque, and in other embodiments, barrier elements may not be capable of being fully transparent or opaque. For instance, such barrier elements may be capable of being 95% transparent when considered to be “transparent” and may be capable of being 5% transparent when considered to be “opaque.” “Transparent” and “opaque” as used herein are intended to encompass barrier elements being substantially transparent (e.g., greater than 75% transparent, including completely transparent) and substantially opaque (e.g., less than 25% transparent, including completely opaque), respectively.
Driver circuitry 102 receives control signals 108 from control circuitry (not shown in
For example,
Each of adaptable parallax barriers 200 and 300, configured in the manner shown in
In the adaptable parallax barrier configurations shown in
For instance,
In still further embodiments, different regions of an adaptable parallax barrier that have parallel non-blocking strips may have the parallel non-blocking strips oriented at different angles to deliver three-dimensional images to viewers that are oriented differently. Thus, a viewing configuration that mixes three-dimensional viewing regions having different viewing orientations may be supported.
For example,
Furthermore, as shown in
As such, in
The foregoing adaptable parallax barriers and arrangements thereof have been described herein by way of example only. Additional adaptable parallax barriers and arrangements thereof may be used to support additional viewing configurations. For example, additional adaptable parallax barrier implementations and arrangements thereof are described in the aforementioned, incorporated U.S. patent application Ser. No. 12/845,440 filed on Jul. 28, 2010, and entitled “Adaptable Parallax Barrier Supporting Mixed 2D and Stereoscopic 3D Display Regions,” and in commonly-owned, co-pending U.S. patent application Ser. No. 12/845,461, filed on Jul. 28, 2010, and entitled “Display Supporting Multiple Simultaneous 3D Views,” the entirety of which is incorporated by reference herein.
Returning now to the description of display system 100 of
For example, in one embodiment, when a configuration of adaptable parallax barrier 124 supports a first viewing configuration responsive to control signals 108, pixel array driver circuitry 204 sends drive signals 152 in conformance with control signals 108 such that the rendering of images to pixel array 122 occurs in a manner that also supports the first viewing configuration. Furthermore, when the configuration of adaptable parallax barrier 124 is modified to support a second viewing configuration responsive to control signals 108, pixel array driver circuitry 204 sends drive signals 152 in conformance with the control signals 108 such that the rendering of images to pixel array 122 occurs in a manner that also supports the second viewing configuration.
Numerous other methods may be used to control the rendering of image pixels to display pixels in support of a desired two-dimensional and/or three-dimensional viewing configuration implemented by an adaptable parallax barrier or other adaptable light manipulator. Additional details concerning such control of a pixel array may be found in the aforementioned, incorporated U.S. patent application Ser. No. 12/774,225, filed on May 5, 2010, and entitled “Controlling a Pixel Array to Support an Adaptable Light Manipulator.”
Light generator 1122 emits light 1132. Adaptable parallax barrier 1124 is positioned proximate to light generator 1122. Barrier element array 1144 is a layer of adaptable parallax barrier 1124 that includes a plurality of barrier elements or blocking regions arranged in an array. Each barrier element of the array is configured to be selectively opaque or transparent. Barrier element array 1144 filters light 1132 received from light generator 1122 to generate filtered light 1134. Filtered light 1134 is configured to enable a two-dimensional image or a three-dimensional image (e.g., formed by a pair of two-dimensional images in filtered light 1134) to be formed based on images subsequently imposed on filtered light 1134 by pixel array 1126.
Pixel array 1126 includes a two-dimensional array of pixels (e.g., arranged in a grid or other distribution) like pixel array 122 of
Driver circuitry 1102 receives control signals 1108 from control circuitry (not shown in
As discussed in the aforementioned, incorporated U.S. patent application Ser. No. ______, filed on even date herewith and entitled “Backlighting Array Supporting Adaptable Parallax Barrier,” conventional LCD displays typically include a backlight and a display panel that includes an array of LCD pixels. The backlight is designed to produce a sheet of light of uniform luminosity for illuminating the LCD pixels. When simultaneously displaying two-dimensional, three-dimensional and multi-view three-dimensional regions using an adaptable parallax barrier such as that described in the aforementioned, incorporated U.S. patent application Ser. No. 12/845,440, filed on Jul. 28, 2010, and entitled “Adaptable Parallax Barrier Supporting Mixed 2D and Stereoscopic 3D Display Regions,” the use of a conventional backlight will result in a disparity in perceived brightness between the different simultaneously-displayed regions. This is because the number of visible pixels per unit area associated with a two-dimensional region will generally exceed the number of visible pixels per unit area associated with a particular three-dimensional or multi-view three-dimensional region (in which the pixels must be partitioned among different eyes/views).
To address this issue, light generator 1122 includes a backlight array 1142 which is a two-dimensional array of light sources. Such light sources may be arranged, for example, in a rectangular grid. Each light source in backlight array 1142 is individually addressable and controllable to select an amount of light emitted thereby. A single light source may comprise one or more light-emitting elements depending upon the implementation. In one embodiment, each light source in backlight array 1142 comprises a single light-emitting diode (LED) although this example is not intended to be limiting.
The amount of light emitted by the individual light sources that make up backlight array 1142 can selectively controlled by drive signals 1152 generated by light generator driver circuitry 1112 so that the brightness associated with each of a plurality of display regions of screen 1104 can also be controlled. This enables display system 1100 to provide a desired brightness level for each display region automatically and/or in response to user input. For example, backlight array 1142 can be controlled such that a uniform level of brightness is achieved across different simultaneously-displayed display regions, even though the number of perceptible pixels per unit area varies from display region to display region. As another example, backlight array 1142 can be controlled such that the level of brightness associated with a particular display region is increased or reduced without impacting (or without substantially impacting) the brightness of other simultaneously-displayed display regions.
To help illustrate this,
In accordance with the example configuration shown in
Of course, the arrangement shown in
In the arrangement shown in
Also, in the examples described above, light sources in backlight array 1212 are described as being individually controllable. However, in alternate embodiments, light sources in backlight array 1212 may only be controllable in groups. This may facilitate a reduction in the complexity of the control infrastructure associated with backlight array 1212. In still further embodiments, light sources in backlight array 1212 may be controllable both individually and in groups. It will be recognized that light generator 1202, adaptable parallax barrier 1204, and display panel 1206 may be controlled based on control signals that are received via a pathway from processing circuitry, such as processing circuitry 162 of
It is also noted that although
Other example display system implementations that utilize a backlight array of independently-controllable light sources are described in the aforementioned, incorporated U.S. patent application Ser. No. ______, filed on even date herewith and entitled “Backlighting Array Supporting Adaptable Parallax Barrier.” That application also describes other approaches for controlling the brightness of different simultaneously-displayed display regions of a display system. Some of these approaches will be described below.
For example, to achieve independent region-by-region brightness control in a display system that includes a conventional backlight panel designed to produce a sheet of light of uniform luminosity, the amount of light passed by the individual pixels that make up a pixel array can be selectively controlled so that the brightness associated with each of a plurality of display regions can also be controlled. To help illustrate this, FIG. 14 provides an exploded view of an exemplary display system 1400 that implements a regional brightness control scheme based on pixel intensity as described immediately above. The regional brightness control scheme may be implemented based on control signals that are received via a pathway from processing circuitry, such as processing circuitry 162 of
As further shown in
Adaptable parallax barrier 1404 includes barrier element array 1422 that includes a first portion 1424 and a second portion 1426. Barrier element array 1422 is aligned with pixel array 1414 such that first portion 1424 of blocking region array 1422 overlays first portion 1414 of pixel array 1412 and second portion 1426 of blocking region array 1422 overlays second portion 1416 of pixel array 1412. Adaptable parallax barrier driver circuitry causes all the barrier elements within first portion 1424 of barrier element array 1422 to be transparent. Thus, the two-dimensional image generated by the pixels of first portion 1414 of pixel array 1412 will simply be passed through to a viewer in a viewing space in front of display system 1400. Furthermore, the adaptable parallax barrier driver circuitry manipulates the barrier elements within second portion 1426 of blocking region array 1422 to form a plurality of parallel transparent strips alternated with parallel opaque strips, thereby creating a parallax effect that enables the two two-dimensional images generated by the pixels of second portion 1416 of pixel array 1412 to be perceived as a three-dimensional image by a viewer in the viewing space in front of display system 1400.
Assume that a viewer is positioned such that he/she can perceive both the two-dimensional image passed by first portion 1424 of barrier element array 1422 and the three-dimensional image formed through parallax by second portion 1426 of barrier element 1422. As discussed above, the pixels per unit area perceived by this viewer with respect to the two-dimensional image will be greater than the pixels per unit area perceived by this viewer with respect to the three-dimensional image. Thus, the two-dimensional image will appear brighter to the viewer than the three dimensional image when backlighting of constant luminosity is provided behind pixel array 1412.
To address this issue, drive signals may be transmitted to display panel 1402 that selectively cause the pixels included in first portion 1414 of pixel array 1412 to pass less light from the backlight panel (i.e., become less intense), thereby reducing the brightness of the two-dimensional image produced from the pixels in first portion 1414 of pixel array 1412. Alternatively or additionally, drive signals may be transmitted to display panel 1402 that selectively cause the pixels included in second portion 1416 of pixel array 1412 to pass more light from the backlight panel (i.e., become more intense), thereby increasing the brightness of the three-dimensional image produced from the pixels in second portion 1416 of pixel array 1412. By controlling the intensity of the pixels in portions 1414 and 1416 of pixel array 1412 in this manner, the brightness of the two-dimensional image produced from the pixels in first portion 1414 of pixel array 1412 and the brightness of the three-dimensional image produced from the pixels in second portion 1416 of pixel array 1412 can be kept consistent. Additionally, by providing independent control over the intensity of the pixels in portions 1414 and 1416 of pixel array 1412, independent control over the brightness of the two-dimensional and three-dimensional images generated therefrom can also be achieved.
Of course, the arrangement shown in
In one embodiment, a regional brightness control scheme combines the use of a backlight array of independently-controllable light sources as previously described with regional pixel intensity control. The advantages of such a control scheme will now be described with reference to
However, the difference in the amount of light emitted by each light source in the first and second portions of the backlight array to illuminate corresponding first and second portions 1504 and 1506 of pixel array 1502 may also give rise to undesired visual artifacts. In particular, the difference may cause pixels in boundary areas immediately outside of second portion 1506 of pixel array 1502 to appear brighter than desired in relation to other pixels in first portion 1504 of pixel array 1502. For example, as shown in
To address this issue, an embodiment may selectively control the amount of light passed by the pixels located in boundary region 1512 or boundary region 1514 to compensate for the undesired visual effects. For example, driver circuitry associated with pixel array 1502 may selectively cause the pixels included in boundary area 1512 of pixel array 1502 to pass less light from the backlight panel (i.e., become less intense), thereby reducing the brightness of the pixels in boundary area 1512, thus compensating for an undesired increase in brightness due to “spill over” from light sources in the second portion of the backlight array. Alternatively or additionally, driver circuitry associated with pixel array 1502 may selectively cause the pixels included in boundary area 1514 of pixel array 1502 to pass more light from the backlight panel (i.e., become more intense), thereby increasing the brightness of the pixels in boundary area 1514, thus compensating for an undesired reduction in brightness due to “spill over” from light sources in the first portion of the backlight array. By controlling the intensity of the pixels in boundary areas 1512 and 1514 in this manner, the undesired visual effects described above that can arise from the use of a backlight array to provide regional brightness control can be mitigated or avoided entirely.
The illustration provided in
In additional embodiments, a regional brightness control scheme is implemented in a display system that does not include a backlight panel at all, but instead utilizes a display panel comprising an array of organic light emitting diodes (OLEDs) or polymer light emitting diodes (PLEDs) which function as display pixels and also provide their own illumination. Display system 100 described above in reference to
Where OLED/PLED pixel regions such as those described above are adjacent to each other, it is possible that the brightness characteristics of one pixel region can impact the perceived brightness of an adjacent pixel region having different brightness characteristics, creating an undesired visual effect. For example, a first OLED/PLED pixel region having a relatively high level of brightness to support the viewing of multi-view three-dimensional content may be adjacent to a second OLED/PLED pixel region having a relatively low level of brightness to support the viewing of two-dimensional content. In this scenario, light from pixels in a perimeter area of the first OLED/PLED pixel region that are close to the boundary between the two pixel regions may “spill over” into a perimeter area of the second OLED/PLED pixel region. This may cause pixels in the perimeter area of the second OLED/PLED pixel region to appear brighter than desired in relation to other pixels in the second OLED/PLED pixel region. Conversely, pixels in the perimeter area of the first OLED/PLED pixel array may appear dimmer than desired in relation to other pixels in the first OLED/PLED pixel region because of the adjacency to the second OLED/PLED pixel region. To address this issue, it is possible to selectively increase or reduce the brightness of one or more OLED/PLED pixels in either perimeter area to reduce the “spill over” effect arising from the different brightness characteristics between the regions.
In still further embodiments, a regional brightness control scheme is implemented in a display system that includes an adaptable parallax barrier that also supports brightness regulation via an “overlay” approach. Such an approach involves the use of a brightness regulation overlay that is either independent of or integrated with an adaptable parallax barrier. The brightness regulation overlay is used to help achieve the aforementioned goals of maintaining standard brightness across various regional screen configurations and compensating for or minimizing backlighting dispersion.
The brightness regulation overlay comprises an element that allows regional dimming through various tones of “grey” pixels. In one example embodiment, an adaptable parallax barrier and the brightness regulation overlay are implemented as a non-color (i.e., black, white and grayscale) LCD sandwich, although other implementations may be used. The combined adaptable parallax barrier and brightness regulation overlay provide full transparent or opaque states for each pixel, as well as a grayscale alternative that can be used to “balance out” brightness variations caused by the parallax barrier itself.
Control over the individual barrier elements of the parallax barrier and the individual grayscale pixels of the brightness regulation overlay may be provided by using coordinated driver circuitry signaling. Such coordinate signaling may cause the pixels of the adaptable parallax barrier and the brightness regulation overlay (collectively referred to below as the manipulator pixels) to create opaque and transparent barrier elements associated with a particular parallax barrier configuration and a grayscale support there between to allow creation of overlays. The regional brightness control scheme described above with reference to
A first exemplary configuration of adaptable light manipulator 1600 is shown above the section line denoted with reference numeral 1602. In accordance with the first exemplary configuration, a three-dimensional region 1604 is created with fully transparent or fully opaque manipulator pixels that provide parallax barrier functionality and a two-dimensional region 1606 is created having continuous medium gray manipulator pixels. The medium gray manipulator pixels operate to reduce the perceived brightness of two-dimensional region 1606 to better match that of three-dimensional region 1604. It is noted that in other example configurations, two-dimensional region 1606 could instead comprise a three-dimensional region having a number of views that is different than three-dimensional region 1604, thus also requiring brightness regulation.
In the first exemplary configuration, no boundary region compensation is performed. In the second exemplary configuration, which is shown below section line 1602, boundary region compensation is performed. For example, a boundary region 1610 within two-dimensional region 1606 may be “lightened” to a light gray to compensate for any diminution of light that might occur near the boundary with three-dimensional region 1604. In contrast, the grayscale level of an inner portion 1608 of two-dimensional region 1606 is maintained at the same medium gray level as in the portion of two-dimensional region 1606 above section line 1602. As a further example, a first boundary region 1612 and a second boundary region 1614 within three-dimensional region 1604 comprise darker and lighter gray transitional areas, respectively, to account for light dispersion from two-dimensional region 1606. In contrast, an inner portion 1616 of three-dimensional region 1604 includes only fully transparent or fully opaque manipulator pixels consistent with a parallax barrier configuration and no brightness regulation.
In one embodiment, the configuration of adaptable light manipulator 1600 is achieved by first creating a white through various grayscale areas that correspond to the regions and boundary areas to be formed. Once established, the manipulator pixels in these areas that comprise the opaque portions of the parallax barrier are overwritten to turn them black. Of course this two-stage approach is conceptual only and no “overwriting” need be performed.
In certain embodiments, adaptable light manipulator 1600 comprises the only component used in a display system for performing brightness regulation and/or boundary region compensation. In alternate embodiments, the display system further utilizes any one or more of the following aforementioned techniques for performing brightness regulation and/or boundary region compensation: a backlight array with independently-controllable light sources, and/or a pixel array and associated control logic for selectively increasing or decreasing the intensity of display pixels (e.g., either LCD pixels or OLED/PLED pixels). Note that in certain embodiments (such as the one described above in reference to
B. Example Display Systems Using Adaptable Lenticular Lenses
In display systems in accordance with further embodiments, rather than using an adaptable parallax barrier to perform light manipulation in support of multiple viewing configurations, an adaptable lenticular lens may be used. For example, with respect to example display system 100 of
Further description regarding the use of an adaptable lenticular lens to deliver three-dimensional views is provided in the aforementioned, incorporated U.S. patent application Ser. No. 12/774,307, filed on May 5, 2010, and entitled “Display with Elastic Light Manipulator.”
C. Example Display Systems Using Multiple Light Manipulators
Display systems in accordance with further embodiments may include multiple layers of light manipulators. Such display systems may enable multiple three-dimensional images to be displayed in a viewing space. The multiple light manipulating layers may enable spatial separation of the images. For instance, in accordance with one embodiment, a display device that includes multiple light manipulator layers may be configured to display a first three-dimensional image in a first region of a viewing space (e.g., a left-side area), a second three-dimensional image in a second region of the viewing space (e.g., a central area), a third three-dimensional image in a third region of the viewing space (e.g., a right-side area), etc. In fact, a display device that includes multiple light manipulator layers may be configured to display any number of spatially separated three-dimensional images as desired for a particular application (e.g., according to a number and spacing of viewers in the viewing space, etc.).
Light 1932 is received at first light manipulator 1924 from pixel array 1922. Pixel array driver circuitry 1912 may generate drive signals 1952 based on a control signal 1908 received from control circuitry (not shown in
First light manipulator 1924 may be configured to manipulate light 1932 received from pixel array 1922. As shown in
Manipulated light 1934 is received by second light manipulator 1926 to generate manipulated light 1936 that includes a plurality of three-dimensional images 1962A-1962N formed in a viewing space 1906. It will be recognized that manipulated light 1936 may include any number N of three-dimensional images. As shown in
As such, screen 1904 of display system 1900 supports multiple viewers with media content in the form of three-dimensional images or views. Screen 1904 may provide a first three-dimensional view based on first three-dimensional media content to a first viewer, a second three-dimensional view based on second three-dimensional media content to a second viewer, and optionally further three-dimensional views based on further three-dimensional media content to further viewers. First and second light manipulators 1924 and 1926 each cause three-dimensional media content to be presented to a corresponding viewer via a corresponding area of screen 1904, with each viewer being enabled to view corresponding media content without viewing media content directed to other viewers. Furthermore, the areas of screen 1904 that provide the various three-dimensional views of media content overlap each other at least in part. In the embodiment of
This section describes exemplary systems and methods that support presentation of multi-path and multi-source viewing content. For example,
In some embodiments, second source 2102B provides a difference file in lieu of the second view portion 2122B. The difference file defines a difference between the first view portion 2122A and the second view portion 2122B. Although the following discussion refers repeatedly to the second view portion 2122B, it will be recognized that the discussion also applies if second source 2102B provides the difference file in lieu of the second view portion 2122B.
Each of first and second sources 2102A and 2102B may be a remote source or a local source. Examples of a remote source include but are not limited to a broadcast media server or an on-demand media server. Examples of a local source include but are not limited to a disc player (e.g., a DVD player, a CD player, or Blu-Ray disc player), a personal computer (e.g., a desktop computer, a laptop computer, or a tablet computer), a personal media player, or a smart phone.
Each of the first and second pathways 2120A and 2120B may include one or more local device pathways, point-to-point links, and/or pathways in a hybrid fiber coaxial (HFC) network, a wide-area network (e.g., the Internet), a local area network (LAN), another type of network, or a combination thereof. Each of the first and second pathways 2120A and 2120B may support wired, wireless, or both transmission media, including satellite, terrestrial (e.g., fiber optic, copper, twisted pair, coaxial, or the like), radio, microwave, free-space optics, and/or any other form or method of transmission.
Media circuitry 2104 is configured to process the first and second view portions 2122A and 2122B to support presentation of 3D viewing content 2134. Media circuitry 2104 includes first circuitry 2112, second circuitry 2114, third circuitry 2116, and fourth circuitry 2118. First circuitry 2112 receives the first and second view portions 2122A and 2122B. For example, if the first and second view portions 2122A and 2122B are encoded, first circuitry 2112 may decode the first and second view portions 2122A and 2122B for further processing by second circuitry 2114. In accordance with this example, if first circuitry 2112 receives the difference file in lieu of the second view portion 2122B from second source 2102B, first circuitry 2112 may decode the first view portion 2122A and the difference file in accordance with one or more techniques described in commonly-owned co-pending U.S. patent application Ser. No. ______, filed on even date herewith and entitled “Video Compression Supporting Selective Delivery of 2D, Stereoscopic 3D and Multi-View 3D Content,” the entirety of which is incorporated by reference herein.
Second circuitry 2114 generates drive signal(s) 2124 based on the first and second view portions 2122A and 2122B. The drive signal(s) 2124 are intended to control screen 2106 to support a visual presentation of the three-dimensional viewing content 2134. For example, second circuitry 2114 may include pixel array driver circuitry (e.g., pixel array driver circuitry 112, 1116, 1912, or 2016) for controlling a pixel array (e.g., pixel array 122, 1126, 1922, or 2028) in screen 2106. In another example, second circuitry 2114 may include light manipulator driver circuitry (e.g., adaptable parallax barrier driver circuitry 114 or 1114, or light manipulator driver circuitry 1914 or 2014) for controlling one or more light manipulators (e.g., adaptable parallax barrier(s) 124 and/or 1124, and/or light manipulator(s) 1924, 1926, 2024 and/or 2026) in screen 2106. In yet another example, second circuitry 2114 may include light generator driver circuitry (e.g., light generator driver circuitry 1112 or 2012) for controlling a light generator (e.g., light generator 1122 or 2022) in screen 2106.
Second circuitry 2114 may synchronize the first view portion 2122A and the second view portion 2122B. Second circuitry may buffer the first view portion 2122A and/or the second view portion 2122B to perform the synchronization.

In accordance with this example, third circuitry 2216 may determine an orientation (e.g., location) of the viewer based on a difference between a time at which third circuitry 2216 transmits the distancing signal and a time at which third circuitry receives the orientation indication 2240. For instance, a reflection of the distancing signal from the viewer may be received by third circuitry 2216 as the orientation indication 2240.
In an embodiment, third circuitry 2216 selects the second view portion 2222B based on the orientation of the viewer, as indicated by the orientation indication 2240. As shown in
In an example, if the orientation indication 2240 indicates that the orientation of the viewer is toward a left side of screen 2206, third circuitry 2216 may select the second view portion 2222B based on the second view portion 2222B representing perspective views that facilitate a left-oriented viewing experience, such as perspective views 1, 2, and 4 of 3D8 viewing content.
