First Claim
Patent Images
1. A method of improving stereo video viewing comfort, the method comprising:
- capturing a video sequence of eyes of an observer viewing a stereo video sequence on a stereoscopic display;
estimating gaze direction of the eyes from the video sequence; and
manipulating stereo images in the stereo video sequence based on the estimated gaze direction, whereby viewing comfort of the observer is improved.

10. A method of improving stereo video viewing comfort, the method comprising:
-
capturing continuously a video sequence of eyes of an observer viewing at least a portion of a first stereo video sequence on a stereoscopic display; estimating gaze directions of the eyes from the video sequence; computing convergence points of the eyes based on the estimated gaze directions; analyzing the computed convergence points to determine a minimum convergence depth and a maximum convergence depth; and using the minimum and maximum convergence depth to adjust horizontal shift of the stereoscopic display as the observer views a second stereo video sequence, whereby viewing comfort of the observer is improved.

11. A stereoscopic display system comprising:
-
a stereo video source configured to provide a stereo video sequence; a stereoscopic display configured to display the stereo video sequence; an eye video capture component configured to capture a video sequence of eyes of an observer viewing the stereo video sequence on the stereoscopic display; and an eye tracking component configured to estimate gaze direction of the eyes from the video sequence, wherein stereo images in the stereo video sequence are manipulated based on the estimated gaze direction, whereby viewing comfort of the observer is improved. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
