Title (EN) METHOD AND APPARATUS FOR DETERMINING AND VARYING THE PANNING SPEED OF AN IMAGE BASED ON SALIENCY
(FR) PROCÉDÉ ET APPAREIL DE DÉTERMINATION ET DE VARIATION DE LA VITESSE DE PANORAMIQUE D'UNE IMAGE SUR LA BASE DU RELIEF
Abstract:
(EN) A method, apparatus and computer program product are provided for varying panning speeds of images based on saliency such that 360-degree images, panoramic images, video images and/or other wide view area images may be efficiently displayed by varying the panning speed such that the user focuses on salient portions of the image. A panning speed is determined based on the currently displayed area and its saliency relative to the saliency of non-displayed or peripheral portions. As a user pans from one area to another, while the user pans over a salient portion of the image, the actual reflected panning may occur at a relatively slower speed than when the user pans over an area not including a salient portion, or a less salient portion.
(FR) L'invention concerne un procédé, un appareil et un produit programme d'ordinateur pour faire varier des vitesses de panoramique d'images sur la base d'un relief de telle sorte que des images à 360 degrés, des images panoramiques, des images vidéo et/ou d'autres images de zone de vue large peuvent être affichées efficacement par variation de la vitesse de panoramique de telle sorte que l'utilisateur se concentre sur des parties saillantes de l'image. Une vitesse de panoramique est déterminée sur la base de la zone actuellement affichée et de son relief par rapport au relief de parties non affichées ou périphériques. À mesure qu'un utilisateur fait un panoramique d'une zone à une autre, alors que l'utilisateur fait un panoramique sur une partie saillante de l'image, le panoramique réfléchi réel peut se produire à une vitesse relativement plus lente que lorsque l'utilisateur fait un panoramique sur une zone ne comprenant pas une partie saillante, ou une partie moins saillante.
