A data processing system includes a rendering system adapted to process data objects to render display frames for presentation via a visual display screen. The display frames include 2D display items corresponding to the data objects, each display item having a 2D screen location within the display frame defined by reference to an X/Y display plane. The rendering system renders stereoscopic 3D views of display frames by rendering left- and right-eye views of the display frames. The left- and right-eye views of the display frames are rendered by processing the data objects corresponding to the 2D display items such that respective left- and right-eye copies of the 2D display items are included in the left- and right-eye views. A set of 3D effects rules is provided that specify relationships between stereoscopic 3D effects and parameters associated with the data objects corresponding to the 2D display items. The stereoscopic 3D effects include lateral offsets in the X-direction of the X/Y display plane to be applied when rendering left- and right-eye copies of display items at respective screen locations, such that selected 2D display items may be perceived by a viewer as being displaced along a Z-axis perpendicular to said X/Y plane. Corresponding computer-implemented methods and computer program products are also included.

A multi-view distribution format is described for stereoscopic and autostereoscopic 3D displays. In general, it comprises multi-tile image compression with the inclusion of one or more depth maps. More specifically, it provides embodiments that utilize stereoscopic images with one or more depth maps typically in the form of a compressed grey scale image and, in some instances, incorporates depth information from a second view encoded differentially.

A method of processing stereoscopic 3D images for display on a 2D display device and viewing using eyewear having a first lens and a second lens includes receiving a first content image stream and an associated second content image stream of common imagery from an image source, where each content image stream has a plurality of image frames. Frame control information is associated with each of the image frames, and the frames of the first and second content streams are interleaved in sequential order to form an interleaved image stream.

Operating systems are described that interface applications and display screens capable of displaying two-dimensional and three-dimensional content. In one aspect, an operating system includes an application programming interface (API), a display driver interface, and a display driver. The API enables one or more applications to deliver requests that define a screen region and either a two-dimension indicator or a three-dimension indicator. The display driver interface passes configuration commands corresponding to the requests. The display driver is associated with a display screen. The display driver receives the configuration commands and responds by generating screen control signals to adjust the display screen to support the screen region.

The present invention includes methods, systems, devices and associated processing logic for generating stereoscopic 3-Dimensional images and/or video from 2-Dimensional images or video. There may be provided a stereoscopic 3D generating system to extrapolate and render 2D complementary images and or video from a first 2D image and/or video. The complementary images and/or video, when combined with the first image or video, or a second complementary image or video, form a stereoscopic image of the scene captured in the first image or video. The stereoscopic 3D generation system may generate a complementary image or images, such that when a viewer views the first image or a second complementary image (shifted in the other direction from the first complementary image) with one eye and the complementary image with the other eye, an illusion of depth in the image is created (e.g. a stereoscopic 3D image).

Provided is a display device including: a viewpoint tracker for detecting a viewpoint variation by tracking a user's viewpoint; a display for alternately displaying a right image and a left image corresponding to user's right eye and left eye; a parallax barrier consisting of sub-segments which are continuously arranged to transmit or block the images by electrical on or off and alternately turned on/off by the unit of groups to alternately form an image transmission region and an image blocking region, in order to provide a 3D image by separately transmitting the right image and the left image to the user's right eye and left eye; and a barrier controller for electrically moving the image transmission region and the image blocking region of the parallax barrier by the unit of sub-segment according to the viewpoint variation, and a method for providing a 3D image of the display device. According to the present invention, it is possible to continuously smoothly provide an autostereoscopic 3D image to a user regardless of a change of a user's viewpoint from a mobile terminal such as a mobile phone or a change of relative position of the mobile terminal.

A sample and hold display such as a Liquid Crystal Display (LCD) monitor that is capable of displaying video signals at a high frame rate, usually at over 120 frames per second, is described. The goal of the monitor is to enable the end user to view stereoscopic 3D images with the use of circular polarized glasses. The display switches between a left perspective view displayed with left handed circular polarization and a right perspective view displayed with right handed circular polarization as stereoscopic 3D images that are viewed with passive analyzing glasses. A horizontally segmented impulse backlight is used to control the timing of the images displayed in synchrony with a horizontally segmented liquid crystal modulator that performs the circular polarization. The impulse backlight and LC modulator eliminate crosstalk while maintaining brightness and high image contrast. Additionally, a unique driving scheme eliminates the appearance of individual segments.

A method for providing stereoscopic three-dimensional (3D) image/video content in a terminal based on Lightweight Application Scene Representation (LASeR) is provided. The method includes receiving a LASeR content including therein stereoscopic 3D image/video information, decoding the received LASeR content according to a stereoscopic 3D image/video attribute, checking LASeR commands from the decoded LASeR content, carrying out the LASeR commands, parsing scene information including stereoscopic 3D image/video information included in the decoded LASeR content, determining whether a media object to be included in scene description is a stereoscopic 3D image/video according to the stereoscopic 3D image/video information and, when the media object to be included in scene description is a stereoscopic 3D image/video, displaying the stereoscopic 3D image/video according to whether the terminal supports a stereoscopic 3D image/video.

A new beam deflection approach is provided for displaying images in autostereoscopic format. Conceptually, polarized light from a display is directed into specific viewing regions using a polarization-sensitive beam deflection sub-system that comprises, in exemplary embodiments, an active liquid crystal quarter-wave plate modulator and a passive cycloidal grating element, such as a diffractive waveplate. Specific embodiments may comprise an illumination system that both floods an LCD panel and creates a defined eye pupil region, from within which the display is viewable. Deflecting the pupil region between left and right eye positions in synchronization with displayed frame sequential stereo image data creates desirable autostereoscopic 3D viewing. Other embodiments employ a similar beam deflection sub-system in conjunction with a means of viewing subsets of pixels from different viewing positions, such as a parallax barrier or lenslet array, allowing freedom of head movement while maintaining stereo viewing.

Further, the synchronization control unit is configured to synchronize refreshing of the display unit and the light transmission control unit, wherein a refreshing rate of the display unit equals to a refreshing rate of the light transmission control unit, and to dynamically adjust the view sequence based on the position information of the one or more viewers.

In telecommunication video calling and videoconferencing systems, it is strongly desirable for remote observers to interact with natural gaze cues. In natural gaze interaction, the camera for a source observer appears to be co-located in the eye region of a destination observer image and vice versa. The appearance of camera co-location is achieved for stereoscopic camera pair that are placed either side of an autostereoscopic 3D display. Such cameras typically provide stereoscopic images that have disparity distributions that provide unnatural perceived head roundness. The present embodiments achieve perceived head roundness that is closer to that expected in natural face to face interaction by modification of perceived local depth in detected regions of the head.

Crosstalk artifacts in a retro-reflective auto-stereoscopic 3D display system are compensated by providing various methods of directing surface reflections of a screen away from a viewing region, i.e. a region from which the screen is viewed. This is achieved by splitting the screen in two, and tilting the left-side and right-side of the screen either towards, or away, from a projection baseline so as to direct mirror reflections away from the viewing region. Alternatively, the screen is not split, but virtical v-shaped grooves are made along the surface of the screen facing the projection line. The angle of the v-shaped groove direct surface reflections away from the viewing region, but the groove are substantially small that the screen appears flat to an observer.
