Title (EN) FOVEATED VIDEO RENDERING
(FR) RESTITUTION DE VIDÉO FOVÉALE
Abstract:
(EN) Techniques are described for generating and rendering video content based on area of interest (also referred to as foveated rendering) to allow 360 video or virtual reality to be rendered with relatively high pixel resolution even on hardware not specifically designed to render at such high pixel resolution. Processing circuitry may be configured to keep the pixel resolution within a first portion of an image of one view at the relatively high pixel resolution, but reduce the pixel resolution through the remaining portions of the image of the view based on an eccentricity map and/or user eye placement. A device may receive the images of these views and process the images to generate viewable content (e.g., perform stereoscopic rendering or interpolation between views). Processing circuitry may also make use of future frames within a video stream and base predictions on those future frames.
(FR) L'invention concerne des techniques pour générer et restituer un contenu vidéo sur la base d'une zone d'intérêt (également appelé restitution fovéale) pour permettre à une vidéo de 360 degrés ou à une réalité virtuelle d'être restituée avec une résolution de pixel relativement élevée, même sur un matériel non conçu spécifiquement pour effectuer une restitution à une telle résolution de pixel élevée. Un circuit de traitement peut être configurée pour garder la résolution de pixel dans une première partie d'une image d'une vue à la résolution de pixel relativement élevée, mais pour réduire la résolution de pixel à travers les parties restantes de l'image de la vue sur la base d'une carte d'excentricité et/ou d'un positionnement d'œil d'utilisateur. Un dispositif peut recevoir les images de ces vues et traiter les images pour générer un contenu pouvant être visualisé (par exemple effectuer une restitution ou une interpolation stéréoscopique entre les vues). Le circuit de traitement peut également utiliser de futures trames dans un flux vidéo et des prédictions de base sur ces futures trames.
