  • Patent number: 9019345
    Abstract: A minimally invasive surgical system includes a scene anti-bloom process that allows switching between imaging modes on a stereoscopic display without causing a surgeon to look-away or being momentarily distracted by sudden changes in overall scene luminance. The process receives a switch from a first imaging mode to a second imaging mode. An overall scene luminance of a scene in the first imaging mode is less than an overall scene luminance of a scene in the second imaging mode. The process delays the switch to the second imaging mode until after an illumination output level of a visible illumination source has changed to a higher output level, and then switches to the second imaging mode.

  • Publication number: 20130127989
    Abstract: Two dimensional data is converted into three dimensional picture data in a method that can provide a real time high quality display during conversion. Pixels of a frame of picture data are segmented to create pixel segments by applying a k-means algorithm. The k-means algorithm groups pixels based on closeness of a combined value that includes luma, chroma, and motion information. By balancing this information the algorithm collects pixels into groups that are assigned relative depths to turn the two-dimensional information into three-dimensional information for display. Another method includes determining a depth map for the different pixel segments by determining an amount of motion of one of the pixel segments between two frames of a video and scaling the three-dimensional depth of one of the pixel segments based on the amount of motion between the two frames.

    Abstract: A volume identification system identifies a set of unlabeled spatio-temporal volumes within each of a set of videos, each volume representing a distinct object or action. The volume identification system further determines, for each of the videos, a set of volume-level features characterizing the volume as a whole. In one embodiment, the features are based on a codebook and describe the temporal and spatial relationships of different codebook entries of the volume. The volume identification system uses the volume-level features, in conjunction with existing labels assigned to the videos as a whole, to label with high confidence some subset of the identified volumes, e.g., by employing consistency learning or training and application of weak volume classifiers. The labeled volumes may be used for a number of applications, such as training strong volume classifiers, improving video search (including locating individual volumes), and creating composite videos based on identified volumes.

    Abstract: A stereoscopic video image display method according to the present invention is such that in a case where switching between a right-eye image and a left-eye image, both of which accommodate a parallax that allows an observer to visually recognize a stereoscopic video image, is done once, for example, every two frames, a gray scale transition emphasis process is carried out in each of the frames, and that in a case where, in a visual recognition period (e.g. frame F2) during which the observer is allowed to visually recognize a stereoscopic video image, display luminance of a target pixel which belongs to a parallax region is made transition from display luminance corresponding to 160 gray scale to display luminance corresponding to 32 gray scale, a gray scale transition emphasis process is carried out so that an average luminance during the visual recognition period becomes substantially equal to the display luminance corresponding to 32 gray scale.

  • Publication number: 20130038686
    Abstract: A video coding device may be configured to code a bitstream including multiple views plus depth information. Two of the views may have reduced resolutions, while a third view may have a full resolution. The third view may be predicted relative to upsampled versions of the two reduced-resolution views. Each view may include texture data and depth data, such that a view component may include a texture component and a depth component. Moreover, the texture and depth components may be arranged within an access unit according to a particular order, which may simplify component extraction from the access unit.

  • Publication number: 20130038703
    Abstract: The present invention relates to data structures, image processing apparatuses, image processing methods, and programs for enabling appropriate processing of video data of 3D content. Obtained content data of 3D content contains video data of 3D images, and information about a reference image size, which is a predetermined image size serving as the reference for the 3D images, and the maximum and minimum parallaxes for the reference image size. An image size detecting unit (71) detects the image size of the video data of the 3D images. If the detected image size of the 3D video data is not the same as the “reference image size,” a maximum/minimum parallax calculating unit (72) calculates the maximum and minimum parallaxes corresponding to the image size of the 3D video data. A caption adjusting unit (73) performs predetermined image processing based on the calculated maximum and minimum parallaxes, such as processing to adjust the depth positions of captions.

  • Publication number: 20130033569
    Abstract: A 3D “pop-up” message is presented to users on a 3D television screen. The 3D message is formatted in such a way that it can be combined, in a post-production environment, with 3D video content. A “message mediator” receives both 3D video content and the 3D message. It also receives information from the 3D content provider about where and when within the 3D content to display the 3D message. The message mediator uses this information to combine the 3D message with the 3D video content and displays the result to the user. Any type of 3D message can be presented including advertisements, personal messages, public-service messages, reminders, and social-networking updates. Some 3D messages can be interactive, responding to user actions. The message mediator can set the transparency and depth of the 3D message to make it more compelling (the 3D message “pops out”) or less intrusive.

  • Publication number: 20130016194
    Abstract: The shutter glasses normally control a right-eye shutter and left-eye shutter even if a control signal to be received is temporarily missed. The image display section displays an image by alternately repeating a right-eye field and a left-eye field, and transmits first control signals synchronously with the right-eye field and left-eye field. The shutter glasses receive the first control signals, and have a right-eye shutter and left-eye shutter for transmitting and blocking visible light. The shutter glasses include a shutter control circuit that stores first timing information for a plurality of fields based on the received first control signals for the plurality of fields and generates second control signals based on the stored first timing information for the plurality of fields. The shutter glasses control the transmission and blocking of visible light at the right-eye shutter and left-eye shutter using the second control signals.

  • Patent number: 8345088
    Abstract: In an autostereoscopic display apparatus comprising a liquid crystal spatial light modulator having an array of pixels of different colors, each pixel comprising plural domains of different polar alignments, and a parallax element comprising an array of optical elements having geometric axes extending in parallel across the spatial light modulator in an inclined direction, the domains are shaped to improve the angular contrast uniformity. For each individual domain, a notional line parallel to the geometric axes of the optical elements of the parallax element has a total length of intersection with the individual domain, summed over adjacent pixels of the same color, is the same for all positions of the notional line. The total length of intersection for different domains is proportional to the area of the individual domains.

  • Publication number: 20120320153
    Abstract: In various embodiment of the present invention, the difference of disparity between subtitles in stereoscopic content along time is restrained by a function of time and disparity. This guarantees that two consecutive subtitles will have similar disparity if they are close in time. More specifically, a method for the positioning of subtitles in stereoscopic content includes estimating a position for a subtitle in at least one frame of the stereoscopic content and restraining a difference in disparity between subtitles in at least two frames by a function of time and disparity. In such an embodiment, the estimating can include computing a disparity value for the subtitle using a disparity of an object in a region in the at least one frame in which the subtitle is to be inserted. The subtitle can then be adjusted to be in front of or behind the object.

  • Publication number: 20120314024
    Abstract: Systems, methods, and devices that control switching of a multi-mode barrier component for efficiently displaying various types of 2-D content and 3-D content are presented. A barrier control component detects an optical signal in a control region of a display screen that is providing visual content to the barrier component, and identifies the type of visual content, such as 2-D content, 3-D stereoscopic content, or 3-D autostereoscopic content, based at least in part on the optical signal. The barrier control component identifies a specified control signal based at least in part on the identified content type, and transmits the specified control signal to the barrier component via a wireline or wireless connection. The barrier component is controlled to automatically switch to a specified mode, such as 2-D mode, 3-D stereoscopic mode, or 3-D autostereoscopic mode, and employ a specified barrier pattern, in response to the received specified control signal.
