Abstract
A method for playing a three-dimensional video is provided, which includes the following steps. A disparity velocity or a disparity acceleration for at least one continuous video in the three-dimensional video is calculated. A visual fatigue estimating value of a viewer is calculated according to the disparity velocity or the disparity acceleration. A subsequent playback of the three-dimensional video is controlled according to the visual fatigue estimating value.
Claims18
A method for playing a three-dimensional video, comprising:
- calculating a disparity velocity or a disparity acceleration for at least one continuous video in the three-dimensional video;
- calculating a visual fatigue estimating value of a viewer according to the disparity velocity or the disparity acceleration;
- and
- controlling a subsequent playback of the three-dimensional video according to the visual fatigue estimating value.
A control system adapted to control a playback of a three-dimensional video, the control system comprising:
- a three-dimensional video stream input unit;
- a disparity estimation unit, coupled to the three-dimensional video stream input unit, wherein the disparity estimation unit calculates a disparity velocity or a disparity acceleration for at least one continuous video in the three-dimensional video;
- a visual fatigue estimation unit, coupled to the disparity estimation unit, wherein the visual fatigue estimation unit calculates a visual fatigue estimating value of a viewer according to the disparity velocity or the disparity acceleration;
- a fatigue recovery control unit, coupled to the three-dimensional video stream input unit and the visual fatigue estimation unit, wherein the fatigue recovery control unit controls a subsequent playback of the three-dimensional video according to the visual fatigue estimating value;
- and
- a three-dimensional video stream display unit, coupled to the fatigue recovery control unit.
