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.
