Abstract

Visual discomfort from depth jumps in 3D video content is reduced or avoided by detecting the occurrence of a depth jump and by changing the disparity of a group of received image frames including the frames at the depth jump in order to adjust the perceived depth in a smooth transition across the group of image frames from a first disparity value to a second disparity value. Depth jumps may be detected, for instance, when content is switched from one 3D shot to another 3D shot.
