STEREO VIEWING
First Claim
1. A method, comprising:
- encoding a plurality of source video signals for stereo viewing, said source video signals comprising video data from a plurality of camera sources, said source video signals comprising active scene area signals and passive scene area signals;
transmitting said plurality of source video signals to a stereo viewing device for viewing;
carrying out at least one of said encoding and transmitting so that in the transmitted source video signals said active scene area signals have been encoded with higher fidelity than said passive scene area signals;
said active and passive scene area signals corresponding to a head orientation of a user so that said active scene area signals correspond to the scene areas the user is viewing and sad passive scene area signals correspond to other scene areas;

Abstract
The invention relates to creating and viewing stereo images, for example stereo video images, also called 3D video. At least three camera sources with overlapping fields of view are used to capture a scene so that an area of the scene is covered by at least three cameras. At the viewer, a camera pair is chosen from the multiple cameras to create a stereo camera pair that best matches the location of the eyes of the user if they were located at the place of the camera sources. That is, a camera pair is chosen so that the disparity created by the camera sources resembles the disparity that the user'"'"'s eyes would have at that location. If the user tilts his head, or the view orientation is otherwise altered, a new pair can be formed, for example by switching the other camera. The viewer device then forms the images of the video frames for the left and right eyes by picking the best sources for each area of each image for realistic stereo disparity.
