Abstract
Three-dimensional color images are produced by combining the red image plane from a left color camera and the blue and green image planes from a right color camera. Techniques for compensating for over or underexposure in a particular image plane are deployed as well as techniques for minimizing subjective disturbance when viewing relatively pure color regions of a 3-dimensional image and for transmission of 3-dimensional color television images to users. TDM and MPEG 2 transmission techniques for stereo image transmission are disclosed. Left and right images are caused to be epipolar to reduce adverse user reaction to extended viewing of stereo images. A three dimensional perspective view may be connected to a stereo view in accordance with the invention.
