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.

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).

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 liquid crystal lens unit is provided for use in an autostereoscopic 3D image display. Light passing through the liquid crstyal lens unit is refracted by a liquid crystal layer arranged by an electric field. The voltage levels applied to the to the liquid crystal layer are periodically changed thereby periodically oscillating the position of the focus profile of the liquid crystal lens unit. As a result, moiré patterns are removed and display quality is improved.

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.

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.

A method for removing noise regions in a stereo 3D image, which includes a first eye image and a second eye image is achieved by calculating a maximum offset value and turning a horizontal synchronization signal and a display enable signal of the CRT timing parameters.

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.
