This application claims the benefit of U.S. Provisional Application No. 61/291,818, filed Dec. 31, 2009, and U.S. Provisional Application No. 61/303,119, filed Feb. 10, 2010, the entireties of which are incorporated by reference herein.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to techniques for displaying images.
2. Background Art
Images may be transmitted 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 the form of two-dimensional images. More recently, images are being provided in digital form for display in two-dimensions on display devices having improved resolution. Even more recently, images capable of being displayed in three-dimensions are being provided.
A parallax barrier is one example of a device that enables images to be displayed in three-dimensions. A parallax barrier includes of a layer of material with a series of precision slits. The parallax barrier is placed proximate to a display so that a viewer's eyes each see a different set of pixels to create a sense of depth through parallax. A lenticular lens is another example of a device that enables images to be displayed in three-dimensions. A lenticular lens includes an array of sub-lenses. As with the parallax barrier, placement of the lenticular lens proximate to an array of pixels enables a viewer's eyes to each see a different set of the pixels. A disadvantage of parallax barriers and lenticular lenses 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 LCD 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. Moreover, conventional three-dimensional LCD displays that utilize lenticular lenses typically are capable of displaying only three-dimensional images.
Commonly-owned, co-pending U.S. patent application Ser. Nos. ______ and ______ present innovative two-dimensional/three-dimensional viewing displays that include adaptable light manipulators to address the aforementioned issues associated with conventional three-dimensional LCD displays that utilize parallax barriers or lenticular lenses. An adaptable light manipulator is a light manipulator (e.g., parallax barrier, lenticular lens, etc.) that is capable of being dynamically modified to accommodate changed circumstances. For example, the viewing displays of U.S. patent application Ser. No. ______ include a parallax barrier that may be dynamically modified in order to adaptively accommodate, for example, a changing viewer sweet spot, switching between two-dimensional images, three-dimensional images, and multi-view three-dimensional content, and the simultaneous display of two-dimensional images, three-dimensional images and multi-view three-dimensional content. The viewing displays of U.S. patent application Ser. No. ______ include an elastic light manipulator (e.g., an elastic parallax barrier, an elastic lenticular lens, etc.) that may be stretched in order to adaptively accommodate, for example, a changing viewer sweet spot and/or that may be retracted to adaptively accommodate, for example, a two-dimensional image mode. However, modifying a configuration of an adaptable light manipulator may negatively affect accuracy of an image as perceived by a viewer.

II. Example EmbodimentsExample embodiments relate to controlling a pixel array to support an adaptable light manipulator. The pixel array is included in an image generator. The adaptable light manipulator is positioned proximate to the image generator to provide an image to a viewer based on light that is received from the image generator. The pixel array includes a plurality of pixels, which are referred to as “display pixels”. Image pixels are rendered among the display pixels, so that a viewer may perceive the image. Image pixels are representations (i.e., signals, data, etc., or a combination thereof) that define respective portions of an image. Example embodiments are capable of changing a number of display pixels that represents each image pixel and/or which display pixels or groups thereof correspond to the respective image pixels, in response to modification of a configuration of an adaptable light manipulator.
The following subsections describe a variety of example embodiments of the present invention. It will be apparent to persons skilled in the relevant art that various changes in form and detail can be made to the embodiments described herein without departing from the spirit and scope of the invention. Thus, the breadth and scope of the present invention should not be limited by any of the example embodiments described herein.
A. Example Display System and Method Embodiments
For instance,
Display device 112 may be configured in various ways. For instance, display device 112 may be a television display (e.g., an LCD (liquid crystal display) television, a plasma television, etc.), a computer monitor, or any other type of display device. Image generator 102 may be any suitable type of image generating device, including but not limited to an LCD screen, a plasma screen, an LED (light emitting device) screen, etc. Adaptable light manipulator 104 may be any suitable type light manipulating device that is capable of being dynamically modified to accommodate changed circumstances.
Although elastic light manipulators are described herein as being stretched along a single axis (e.g., axis 114) for purposes of illustration, the example embodiments are not limited in this respect. It will be recognized that the elastic light manipulators described herein may be stretched along multiple axes. For instance, adaptable light manipulator 104 may be stretched along a second axis in addition to or in lieu of being stretched along axis 114. For example, the second axis may be perpendicular to axis 114.
Pixel array 208 includes a two-dimensional array of pixels (e.g., arranged in a grid). The pixels of pixel array 208 may each emit light included in light 108. Each pixel may be a separately addressable light source (e.g., a pixel of a plasma, LCD, or LED display) and/or may include a filter that filters light received from a separate or included light source. Each pixel of pixel array 208 may be individually controllable to vary color and intensity. In an embodiment, each pixel of pixel array 208 may include a plurality of sub-pixels that correspond to separate color channels, such as a trio of red, green, and blue sub-pixels that is included in each pixel.
Adaptable light manipulator 104 is positioned proximate to a surface of pixel array 208. Adaptable light manipulator 104 may be configured to be stretchable along axis 114, though the scope of the example embodiments is not limited in this respect. For example,
Adaptable light manipulator 300 is configured to be stretchable along axis 114. For instance,
In another example,
Each blocking region 604 of blocking region array 602 is selectable to be opaque or transparent. For instance,
Display controller 202 is configured to generate control signals (and in some embodiments, to stretch adaptable light manipulator 104) to enable display device 112 to display two-dimensional and three-dimensional images to users 212 in viewing space 106. For example, pixel array controller 204 is configured to generate a control signal 214 that is received by pixel array 208. Control signal 214 may include one or more image pixels and a mapping indicator that maps the image pixels to respective subsets of pixels of pixel array 208. For instance, control signal 214 may cause the subsets of the pixels of pixel array 208 to emit light 108 of desired colors and/or intensities. Each subset may include one or more pixels of pixel array 208. Manipulator controller 206 is configured to generate a control signal 216 that is received by adaptable light manipulator 104 and/or to provide a tensile stress along axis 114 to stretch adaptable light manipulator 104. When a configuration of adaptable light manipulator 104 is modified based on control signal 216 and/or a tensile stress, pixel array controller 204 updates control signal 214 to include a revised mapping indicator that maps the image pixels to other respective subsets of pixels of pixel array 208. A more detailed discussion of some example techniques for controlling a pixel array to support an adaptable light manipulator is provided below in section II.E with reference to
In embodiments in which adaptable light manipulator 104 includes an elastic light manipulator (e.g., elastic lenticular lens 300), stretching elastic light manipulator 104 causes the optical properties of adaptable light manipulator 104 to change, so that adaptable light manipulator 104 manipulates light 108 in accordance with the changed optical properties to generate manipulated light 110 that includes one or more two-dimensional and/or three-dimensional images that may be viewed by users 212 in viewing space 106.
For example, control signal 214 may control multiple sets of pixels of pixel array 208 to each emit light representative of a respective image, to provide a plurality of images. Manipulator controller 206 may stretch adaptable light manipulator 104 to manipulate the light received from pixel array 208 corresponding to the provided images such that one or more of the images are received at one or more of users 212 in two-dimensional form. Furthermore, manipulator controller 206 may stretch adaptable light manipulator 104 to manipulate the light received from pixel array 208 corresponding to at least one pair of the provided images such that the image pair is received at one or more of the users to be perceived as a three-dimensional image.
Manipulator controller 206 may be further configured to perform any of a variety of other operations with respect to adaptable light manipulator 104, though the example embodiments are not limited in this respect. For example, manipulator controller 206 may be configured to change a curvature of adaptable light manipulator 104 and/or an angle at which adaptable light manipulator 104 is mounted with respect to pixel array 208. Such changes may be performed to accommodate a moving user based on a location of the user's head, for instance.
In another example, manipulator controller 206 may be configured to retract adaptable light manipulator 104, such that adaptable light manipulator 104 (or a portion thereof) is removed from a position that is between pixel array 208 and users 212. For instance, retracting adaptable light manipulator 104 may provide an unfiltered view of some or all of the pixels in pixel array 208. Accordingly, retracting adaptable light manipulator 104 may enable one or more of the users to view a two-dimensional image that is generated by pixels of pixel array 208 that are not covered by adaptable light manipulator 104, even if adaptable light manipulator 104 is configured to provide a three-dimensional image with respect to other pixels of pixel array 208.
In embodiments in which adaptable light manipulator 104 includes an adaptable parallax barrier (e.g., adaptable light manipulator 600), control signal 216 may include one or more control signals used to cause blocking regions 604 of blocking region array 602 to be transparent or opaque to filter light 108 to facilitate the generation of manipulated light 110 that includes one or more two-dimensional and/or three-dimensional images that may be viewed by users 212 in viewing space 106.
In accordance with these embodiments, control signal 216 may control blocking regions 604 of blocking region array 602 to filter the light received from pixel array 208 corresponding to the provided images such that one or more of the images are received at one or more of users 212 in two-dimensional form. For instance, control signal 216 may select one or more sections of blocking regions 604 of blocking region array 602 to be transparent, to transmit one or more corresponding two-dimensional images to users 212. Furthermore, control signal 216 may control blocking regions 604 of blocking region array 602 to filter the light received from pixel array 208 corresponding to at least one pair of the provided images such that the image pair is received at one or more of the users to be perceived as a three-dimensional image. For example, control signal 216 may select parallel strips of blocking regions 604 of blocking region array 602 to be transparent to form a three-dimensional image to be perceived by one or more of users 212.
In further accordance with these embodiments, manipulator controller 206 may generate control signal 216 to form any number of parallel strips of blocking regions 604 of blocking region array 602 to be transparent, to modify the number and/or spacing of parallel strips of blocking regions 604 of blocking region array 602 that are transparent, to select and/or modify a width and/or a length (in blocking regions 604) of one or more strips of blocking regions 604 of blocking region array 602 that are transparent, to select and/or modify an orientation of one or more strips of blocking regions 604 of blocking region array 602 that are transparent, to select one or more areas of blocking region array 602 to include all transparent or all opaque blocking regions 604, etc.
B. Additional Information Regarding Example Elastic Light Manipulator Embodiments
Two-dimensional and three-dimensional images may be generated by system 200 in various ways, in embodiments. For instance,
Flowchart 900 begins with step 902. In step 902, a plurality of images is received from an array of pixels at an elastic light manipulator. For example, as shown in
In step 904, the elastic light manipulator is stretched from a first length to a selectable second length to provide the plurality of images to a plurality of respective locations. For example, as shown in
For example, elastic light manipulator 1004 may refract a first portion of the light emanating from pixel array 1002 that corresponds to first image 1006A such that first image 1006A is perceived at first location 1008A but not at second location 1008B. For instance, the first portion of the light is shown in
C. Additional Information Regarding Example Adaptable Parallax Barrier Embodiments
Flowchart 1100 begins with step 1102. In step 1102, light is received from a surface at an adaptable parallax barrier that is positioned proximate to the surface. For example, as shown in
In step 1104, each blocking region in a plurality of parallel strips of blocking regions of the blocking region array is selected to be transparent to form a plurality of parallel transparent slits, the number of transparent slits in the plurality of parallel transparent slits being selectable. For example, as shown in
For instance,
In step 1106, the light is filtered at the parallax barrier to form a plurality of images in a viewing space. For example, as shown in
By forming parallel transparent slits in a blocking region array, light from a pixel array can be filtered to form multiple images in a viewing space. For instance, system 1200 shown in
For example, in embodiments in which the adaptable light manipulator is implemented as an elastic parallax barrier, the geometry of transparent blocking regions 1212 may be based on an extent to which blocking region array 1204 is stretched. In accordance with this example, a greater extent of stretching may result in opaque blocking regions 1210 having a greater length W1 and/or transparent blocking regions 1212 having a greater length W2. Accordingly, the greater extent of stretching may result in a greater slit spacing 1222 (center-to-center). Slit spacing 1222 is described in greater detail in the following discussion. A lesser extent of stretching may result in opaque blocking regions 1210 having a lesser length W1 and/or transparent blocking regions 1212 having a lesser length W2. Accordingly, the lesser extent of stretching may result in a narrower slit spacing 1222.
As shown in
D. Example Multi-Three-Dimensional Image Embodiments
In an embodiment, a display system (e.g., display system 1000 of
Referring to
In such an embodiment, first and second images 1006A and 1006B may be formed by display system 1000 such that their centers are spaced apart a width of a user's pupils (e.g., an “interocular distance”, labeled as “X” in
In a further embodiment, display system 1000 may be configured to generate multiple three-dimensional images for viewing by users in a viewing space. Each of the three-dimensional images may correspond to a pair of images generated by sets of pixels of pixel array 1024. Adaptable light manipulator 1004 manipulates light from pixel array 1024 to form the image pairs in a viewing space to be perceived by users as three-dimensional images. Adaptable light manipulator 1004 is shown to be implemented as an elastic lenticular lens for illustrative purposes and is not intended to be limiting. For instance,
In the example of
As shown in
It is noted that multiple instances of each of first-fourth images 1506A-1508D may be formed in viewing space 1526 in a repeating fashion due to the optical characteristics of adaptable light manipulator 1004. As shown in
In the embodiment of
In the example of
E. Example Pixel Array Controlling Embodiments
As mentioned above, mapping of image pixels to display pixels may be changed to accommodate modification of a configuration of an adaptable light manipulator. For instance, changing the mapping of the image pixels with respect to the display pixels may enable a viewer to perceive an accurate rendering of an image that is defined by the image pixels. The mapping of the image pixels may be changed in any of a variety of ways, including but not limited to changing a number of display pixels that represents each image pixel, changing the display pixels or groups thereof that correspond to the respective image pixels, etc.
Locator 1604 is configured to determine whether a position of a viewer is changed with respect to the pixel array. For example, locator 1604 may be configured to provide a position indicator to manipulator controller 1602 upon determining that the position of the viewer is changed with respect to the pixel array. In accordance with this example, manipulator controller 1604 may be configured to modify the configuration of the adaptable light manipulator in response to receiving the position indicator from locator 1604.
Pixel array controller 1606 is configured to control the pixel array to support the adaptable light manipulator. Pixel array controller 1606 includes a conversion module 1608 and a mapping module 1610. Conversion module 1608 is configured to convert image pixels among various formats. For instance, conversion module 1608 may be configured to convert image pixels that correspond to a two-dimensional representation of an image to image pixels that correspond to a three-dimensional representation of the image, or vice versa.
Mapping module 1610 is configured to map image pixels among the display pixels of the pixel array. For example, mapping module 1610 may be configured to initially map the image pixels to respective first subsets of the display pixels. In accordance with this example, mapping module 1610 may be further configured to map the image pixels to respective second subsets of the display pixels in response to determining that manipulator controller 1602 has modified the configuration of the adaptable light manipulator.
It will be recognized that display controller 1600 may not include one or more of manipulator controller 1602, locator 1604, pixel array controller 1606, conversion module 1608, and/or mapping module 1610. Furthermore, display controller 1600 may include modules in addition to or in lieu of manipulator controller 1602, locator 1604, pixel array controller 1606, conversion module 1608, and/or mapping module 1610.
As shown in
At step 1704, a configuration of an adaptable light manipulator that is positioned proximate to the pixel array is changed. For example, in implementations in which the adaptable light manipulator includes an adaptable parallax barrier, a slit pattern, an orientation, etc. of the adaptable parallax barrier may be changed. In implementations in which the adaptable light manipulator includes an elastic light manipulator, an extent to which the elastic light manipulator is stretched may be changed; an orientation of the elastic light manipulator may be changed, etc. The orientation of an adaptable light manipulator may be changed by moving the adaptable light manipulator in any direction with respect to the pixel array, rotating the adaptable light manipulator, changing an angle between the adaptable light manipulator and the pixel array, etc. In an example implementation, manipulator controller 1602 changes the configuration of the adaptable light manipulator.
At step 1706, a mapping of the plurality of image pixels is changed from the plurality of respective first subsets of the display pixels to a plurality of respective second subsets of the display pixels in the pixel array to compensate for changing the configuration of the adaptable light manipulator. For example, the mapping of the plurality of image pixels may be changed in response to changing the configuration of the adaptable light manipulator. In another example, the mapping of the plurality of image pixels may be changed on-the-fly. In yet another example, each of the first subsets and each of the second subsets may include the same number of display pixels. In still another example, each of the first subsets may include a first number of display pixels, and each of the second subsets may include a second number of pixels that is different from the first number. In an example implementation, mapping module 1610 changes the mapping of the plurality of image pixels from the plurality of respective first subsets of the display pixels to the plurality of respective second subsets of the display pixels.
As shown in
At step 1804, a number of the display pixels in the pixel array that represents each image pixel of a plurality of image pixels is changed in response to modifying the configuration of the adaptable light manipulator. For instance, the number of the display pixels in the pixel array that represents each image pixel may be changed on-the-fly. In an example implementation, mapping module 1610 changes the number of the display pixels in the pixel array that represents each image pixel of the plurality of image pixels.
In an example embodiment, subsets 2102, 2104, 2106, and 2108 correspond to a two-dimensional representation of an image. In accordance with this example embodiment, subsets 2102, 2104, 2106, and 2108 are configured to be perceived by a viewer as respective portions of a two-dimensional image. Accordingly, mapping 2100 may correspond to a two-dimensional mode of operation of pixel array 2110.
As shown in
In an example embodiment, subsets 2202, 2204, 2206, 2208, 2210, 2212, 2214, and 2216 correspond to a three-dimensional representation of an image. In accordance with this example embodiment, subsets 2202 and 2204 combine to be perceived by a viewer as a first portion of a three-dimensional image; subsets 2206 and 2208 combine to be perceived by the viewer as a second portion of the three-dimensional image; subsets 2210 and 2212 combine to be perceived by the viewer as a third portion of the three-dimensional image; and subsets 2214 and 2216 combine to be perceived by the viewer as a fourth portion of the three-dimensional image. Accordingly, mapping 2200 may correspond to a first three-dimensional mode of operation of pixel array 2110 in which pixel array 2110 provides a single three-dimensional image.
As shown in
In an example embodiment, subsets 2302, 2306, 2310, 2314, 2318, 2322, 2326, and 2330 correspond to a three-dimensional representation of a first image, and subsets 2304, 2308, 2312, 2316, 2320, 2324, 2328, and 2332 correspond to a three-dimensional representation of a second image. In accordance with this example embodiment, subsets 2302 and 2306 combine to be perceived by a viewer as a first portion of a first three-dimensional image; subsets 2310 and 2314 combine to be perceived by the viewer as a second portion of the first three-dimensional image; subsets 2318 and 2322 combine to be perceived by the viewer as a third portion of the first three-dimensional image; and subsets 2326 and 2330 combine to be perceived by the viewer as a fourth portion of the first three-dimensional image. In further accordance with this example embodiment, subsets 2304 and 2308 combine to be perceived by a second viewer as a first portion of a second three-dimensional image; subsets 2312 and 2316 combine to be perceived by the second viewer as a second portion of the second three-dimensional image; subsets 2320 and 2324 combine to be perceived by the second viewer as a third portion of the second three-dimensional image; and subsets 2328 and 2332 combine to be perceived by the second viewer as a fourth portion of the second three-dimensional image.
In another example embodiment, subsets 2302, 2304, 2310, 2312, 2318, 2320, 2326, and 2328 correspond to a three-dimensional representation of a first image, and subsets 2306, 2308, 2314, 2316, 2322, 2324, 2330, and 2332 correspond to a three-dimensional representation of a second image. In accordance with this example embodiment, subsets 2302 and 2304 combine to be perceived by a viewer as a first portion of a first three-dimensional image; subsets 2310 and 2312 combine to be perceived by the viewer as a second portion of the first three-dimensional image; subsets 2318 and 2320 combine to be perceived by the viewer as a third portion of the first three-dimensional image; and subsets 2326 and 2328 combine to be perceived by the viewer as a fourth portion of the first three-dimensional image. In further accordance with this example embodiment, subsets 2306 and 2308 combine to be perceived by a second viewer as a first portion of a second three-dimensional image; subsets 2314 and 2316 combine to be perceived by the second viewer as a second portion of the second three-dimensional image; subsets 2322 and 2324 combine to be perceived by the second viewer as a third portion of the second three-dimensional image; and subsets 2330 and 2332 combine to be perceived by the second viewer as a fourth portion of the second three-dimensional image.
Accordingly, mapping 2300 may correspond to a second three-dimensional mode of operation of pixel array 2110 in which pixel array 2110 provides two three-dimensional images. For instance, each of the two three-dimensional images may use a respective half of the display pixels 2112 in pixel array 2110, as described above.
Pixel array 2110 is shown in
As shown in
In an example embodiment, instead of (or in addition to) determining that the position of the user with respect to the pixel array is changed, a determination is made that an orientation of the user's head with respect to the pixel array is changed. For example, a determination may be made that the user's head is rotated from a substantially vertical orientation to a substantially horizontal orientation (as may occur if the user goes from a seated or standing position to a lying position), or vice versa. It will be recognized that the orientation of the user's head need not necessarily be substantially vertical or substantially horizontal. For instance, the orientation of the user's head may be at an angle between substantially vertical and substantially horizontal.
At step 1904, a configuration of an adaptable light manipulator is modified in response to determining that the position of the user with respect to the pixel array is changed. The adaptable light manipulator receives light from the pixel array. In an example implementation, manipulator controller 1602 modifies the configuration of the adaptable light manipulator.
At step 1906, subsets of the plurality of display pixels to which respective image pixels are rendered are changed to compensate for the configuration of the adaptable light manipulator being modified. For example, the subsets of the plurality of display pixels to which the respective image pixels are rendered may be changed in response to the configuration of the adaptable light manipulator being modified. In another example, the subsets of the plurality of display pixels to which the respective image pixels are rendered may be changed on-the-fly. In an example implementation, mapping module 1610 changes the subsets of the plurality of display pixels to which the respective image pixels are rendered.
In one example embodiment, step 1902 of flowchart 1900 is not performed. In accordance with this embodiment, the configuration of the adaptable light manipulator is modified at step 1904 even in the absence of determining that the position of the user with respect to the pixel array is changed.
Pixel array 2402 includes a plurality of subsets 2406A-2406I of display pixels arranged in a series. Further subsets of display pixels may be included in pixel array 2402 that are not visible in
It will be recognized that any of a variety of factors may affect the mapping of image pixels 2416A-2416H among subsets 2406A-2406I. Such factors may include but are not limited to changing the position of the user 2424 with respect to pixel array 2402, changing the spacing of subsets 2406A-2406I, and/or changing the configuration of adaptable light manipulator 2404.
For example, display system 2500 of
In the example embodiment of
In
As shown in
At step 2004, a configuration of an adaptable light manipulator that receives light from the pixel array is changed. In an example implementation, manipulator controller 1602 changes the configuration of the adaptable light manipulator.
At step 2006, the first plurality of image pixels is converted to a second plurality of image pixels that corresponds to an M-dimensional representation of the image. M is not equal to N. For instance, the first plurality of image pixels may be converted to the second plurality of image pixels on-the-fly. In an example embodiment, M=2 and N=3. In another example embodiment, M=3 and N=2. In an example implementation, conversion module 1608 converts the first plurality of image pixels to the second plurality of image pixels.
At step 2008, the second plurality of image pixels is rendered to the plurality of display pixels in response to changing the configuration of the adaptable light manipulator. For instance, the second plurality of image pixels may be rendered in lieu of the first plurality of image pixels to the plurality of display pixels. In an example implementation, mapping module 1610 renders the second plurality of image pixels to the plurality of display pixels.
III. Example Display Controller ImplementationsDisplay controller 202, pixel array controller 204, and manipulator controller 206 may be implemented in hardware, software, firmware, or any combination thereof. For example, display controller 202, pixel array controller 204, and/or manipulator controller 206 may be implemented as computer program code configured to be executed in one or more processors.
