Abstract

La invención se refiere a crear y visualizar imágenes estereoscópicas, por ejemplo imágenes de vídeo estéreo, también denominado vídeo 3D. Al menos se usan tres orígenes de cámara con campos de visión solapante para capturar una escena de modo que un área de la escena esté cubierta por al menos tres cámaras. En el visualizador, se elige un par de cámaras desde las múltiples cámaras para crear un par de cámaras estéreo que mejor coincida con la localización de los ojos del usuario si estuvieran localizados en el lugar de los orígenes de cámara. Es decir, se elige un par de cámaras de modo que la disparidad creada por los orígenes de cámara se asemeje a la disparidad que los ojos del usuario tendrían en esa localización. Si el usuario inclina su cabeza, o se modifica de otra manera la orientación de la vista, puede formarse un nuevo par, por ejemplo cambiando a la otra cámara. El dispositivo visualizador a continuación forma las imágenes de los fotogramas de vídeo para los ojos izquierdo y derecho tomando los mejores orígenes para cada área de cada imagen para una disparidad estéreo realista.
