Abstract: The disclosure is directed to a method to compensate for visual distortion when viewing video image streams from a multiple camera capture of a scene where the method determines the disparity difference utilizing the user view orientation and then compresses and/or stretches the left and/or right eye video image streams to compensate for the visual distortion. In another aspect, the method describes additional adjustments and corrections to the video image streams including rotating, tilting, shifting, and scaling the video image streams, and correcting for gapping and clipping visual image artifacts. In another aspect, a visual compensation system is described to implement the method. Additionally, a visual compensation apparatus is disclosed to perform the method operations.

Abstract: A system for multi-client control of a common avatar is provided herein. The system includes, for example, a cloud game engine and a cooperative play engine associated with the cloud game engine and configured to multicast a video stream from the cloud game engine to multiple players, combine separate response streams from the multiple players into a joint response stream based on avatar functions contained therein and provide the joint response stream to the cloud game engine.

Abstract: Due to the factors such as lens distortion and camera misalignment, stereoscopic image pairs often contain vertical disparities. Introduced herein is a method and apparatus that determine and correct vertical disparities in stereoscopic image pairs using an optical flow map. Instead of discarding vertical motion vectors of the optical flow map, the introduced concept extracts and analyzes the vertical motion vectors from the optical flow map and vertically aligns the images using the vertical disparity determined from the vertical motion vectors. The introduced concept recognizes that although not apparent, vertical motion does exist in stereoscopic images and can be used to correct the vertical disparity in stereoscopic images.

Abstract: An apparatus for capturing digital stereoscopic images of a scene. The apparatus comprises a first pair of separated camera lens oriented such that a first imaginary line between the first pair of lens is substantially parallel with a horizon line a scene, wherein digital image data is capturable through the first pair of camera lens and storable in two separate digital image data bases corresponding to a left-eye horizontal view and a right-eye horizontal view respectively. The apparatus comprises a second pair of separated camera lens oriented such that a second imaginary line between the second pair of lens is substantially non-parallel with the horizon line, wherein digital image data is capturable through the second pair of camera lens and storable in two separate digital image data bases corresponding to a left-eye off-horizontal view and a right-eye off-horizontal view respectively.
