CA 2729995

The playback apparatus realizes stereoscopic viewing by overlaying planar or stereoscopic graphics over stereoscopic video in a way that reduces eye strain using following method in abstract: A graphics plane holds therein data composed of graphics data. A shift engine shifts, in a case when a composition unit composites the graphics data with a left-view video frame, coordinates of each of the pixels is shifted in a first horizontal direction, and in a case when the composition unit composites the graphics data with a right-view video frame, coordinates of each of the pixels is shifted in a second horizontal direction that is opposite to the first direction.

L'invention concerne un dispositif de reproduction créant une sensation de relief en émettant chaque image dune pluralité dimages vidéo stockées dans un plan vidéo sous la forme dune image vidéo en vision droite et dune image vidéo en vision gauche. Un plan graphique mémorise les données dimage à des résolutions de 1920 x 1080 et 1280 x 720 pixels en tant que données graphiques, et un moteur de décalage décale les coordonnées de chaque objet de données dimage dans le plan graphique vers la droite ou vers la gauche afin de réaliser la sortie en vision gauche, tout en décalant également les coordonnées de chaque objet de données dimage dans le plan graphique dans le sens opposé à la vision gauche afin de réaliser la sortie en vision droite.
