Abstract
A stereoscopic video processing apparatus is constituted by: a video input section, for receiving input of stereoscopic videos constituted by a plurality of frames, which are viewable stereoscopically; a scene detecting section, for detecting positions within the stereoscopic videos at which scene changes occur; and a perceived depth adjusting section, for administering perceived depth adjusting processes that adjust the perceived depths of the stereoscopic videos such that the perceived depth changes gradually at the positions at which scene changes occur.
Claims16
A stereoscopic video processing apparatus, comprising:
- a video input unit, for receiving input of stereoscopic videos constituted by a plurality of frames, which are viewable stereoscopically;
- a scene detecting unit, for detecting positions within the stereoscopic videos at which scene changes occur;
- and
- a perceived depth adjusting unit, for administering a perceived depth adjusting process comprising the steps of:
- displaying a leading perceived depth adjusting frame corresponding to the leading frame of a scene to be processed or the last frame of a preceding scene and having a perceived depth corresponding to that of the last frame, following display of the last frame of a preceding scene;
- displaying a number of perceived depth adjusting frames, in which the perceived depth changes continuously from that of the leading perceived depth adjusting frame to that of the leading frame;
- and
- displaying the leading frame and the frames following thereafter, after the perceived depth adjusting frames are displayed, to generate processed stereoscopic videos.
