METHOD OF PRESENTING THREE-DIMENSIONAL CONTENT WITH DISPARITY ADJUSTMENTS
First Claim
1. A method for presenting stereoscopic content comprising a plurality of sequential stereoscopic image pairs, each image pair including a first view and a second view, the method comprising:
- detecting an occurrence of a depth jump between a first and a second image pairs of the plurality of image pairs, the first and second image pairs being consecutive pairs characterized respectively by a first disparity and a second disparity with the first image pair preceding the second image pair; and
changing respective disparities for at least the first and second image pairs, a third image pair preceding the first image pair, and a fourth image pair after the second image pair for use in presenting the stereoscopic content;
wherein, after changing the respective disparities, any two consecutive image pairs appearing between the third and fourth image pairs has a disparity difference that is less than a difference between the first disparity and the second disparity.

Abstract
Visual discomfort from depth jumps in 3D video content is reduced or avoided by detecting the occurrence of a depth jump and by Input video 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.

17. A system for presenting stereoscopic content comprising a plurality of sequential stereoscopic image pairs, each image pair including a first view and a second view, the system comprising:
-
at least one processor for detecting an occurrence of a depth jump between a first and a second image pairs of the plurality of image pairs, the first and second image pairs being consecutive pairs characterized respectively by a first disparity and a second disparity with the first image pair preceding the second image pair, and for changing respective disparities for at least the first and second image pairs, a third image pair preceding the the first image pair, and a fourth image pair after the second image pair for use in presenting the stereoscopic content, wherein, after changing the respective disparities, any two consecutive image pairs appearing between the third and fourth image pairs has a disparity difference that is less than a difference between the first disparity and the second disparity, and a display for displaying at least one stereoscopic image pair output from said at least one processor.
