Description

前記の課題を解決するため、本発明の映像再生方法及び装置、並びに映像表示方法及び装置では、
該立体映像コンテンツから視差又は距離を検出し、
前記立体映像コンテンツを高速再生するとき、前記検出した視差又は距離に対して、視差又は距離の変化量を縮小した映像信号を出力し、
該縮小において、通常再生時と比べ、高速再生時の視差又は距離の変化量を再生速度に応じて縮小することを特徴とする。 In order to solve the above-mentioned problem, in the video reproduction method and apparatus and the video display method and apparatus of the present invention,
Detecting parallax or distance from the stereoscopic video content,
When the stereoscopic video content is played back at high speed, a video signal in which the amount of change in parallax or distance is reduced with respect to the detected parallax or distance is output;
The reduction is characterized in that the amount of change in parallax or distance during high-speed playback is reduced according to the playback speed as compared with normal playback .

Claims
