Title (EN) VIRTUAL THEATER
(FR) THEATRE VIRTUEL
Abstract: front page image
(EN)A method and apparatus for projecting perspectively corrected spherical video images in a theater environment is disclosed. First, video signals and associated audio signals are stored (14). The direction of view of a user is then tracked (60, 62) to create sufficient feedback information which is then provided to a processor (50). The video signals and audio signals are then provided to the processor (50). The processor then orients the video signal based on the position feedback information and then perspectively corrects the video signal. The audio signal is oriented based on the orientation of the perspectively corrected video signal. The perspectively corrected video signal and the oriented audio signals are then provided to a projection system (64), wherein the perspectively corrected video signals are projected on a screen and said oriented audio signals create an impression of a three-dimensional sound field.
(FR)L'invention concerne un procédé et un appareil permettant de projeter des images vidéo sphériques avec correction de perspective dans un théâtre. Les signaux vidéo et les signaux audio associés sont stockés (14). L'orientation de l'observation d'un utilisateur est ensuite suivie (60, 62) pour créer une quantité d'informations en retour suffisante pour être envoyée à un processeur (50). Les signaux vidéo et les signaux audio sont ensuite acheminés vers le processeur qui oriente le signal vidéo selon les informations en retour sur la position et effectue une correction de perspective de ce signal vidéo. Le signal vidéo corrigé et les signaux audio orientés sont ensuite envoyés vers un système de projection (64) servant à projeter les signaux vidéo corrigés sur un écran alors que les signaux audio orientés créent une impression de champ sonore tridimensionnel.
