Abstract
(EN)
The present technology relates to a video playback device, a playback method, and a program whereby it is possible to suppress a reduction in the degree of immersion of a viewer. This video generation device acquires a first 3D shape video which is generated from a plurality of viewpoint videos obtained by capturing an image of a subject from different viewpoints, and a second 3D shape video different from the first 3D shape video, and switches a frame to be played back, from a frame of the first 3D shape video to a frame of the second 3D shape video, on the basis of the state of the viewer viewing the first 3D shape video. The present disclosure can be applied to, for example, a video generation device, a video processing device, and a video playback device.

La présente invention concerne un dispositif de lecture vidéo, un procédé de lecture, et un programme, aptes à supprimer une réduction du degré d'immersion d'un spectateur. Le dispositif de génération vidéo selon l'invention : acquiert une première vidéo de forme 3D qui est générée à partir d'une pluralité de vidéos de point de vue obtenues par la capture d'une image d'un sujet à partir de différents points de vue, et une seconde vidéo de forme 3D différente de la première vidéo de forme 3D ; et commute une trame devant être lue, d'une trame de la première vidéo de forme 3D à une trame de la seconde vidéo de forme 3D sur la base de l'état du spectateur qui regarde la première vidéo de forme 3D. La présente invention peut être appliquée, par exemple, à un dispositif de génération vidéo, un dispositif de traitement vidéo, et un dispositif de lecture vidéo.
