Patent

CA 2728036

A device and method of background substitution are dis-closed. One or more cameras in a mobile device obtain a depth image. A processor in or external to the device segments the foreground from the background of the image. The original background is removed and a stored background image or video is substituted in place of the original back-ground. The substituted background is altered dependent on the attitude and motion of the device, which is sensed by one or more sensors in the device. A portion of the stored background selected as the substitute back-ground varies in correspondence with the device movement.

Linvention concerne un dispositif et un procédé de substitution d'un arrière-plan. Une ou plusieurs caméras embarquées dans un dispositif mobile acquièrent une image de profondeur. Un processeur placé à l'intérieur ou à l'extérieur du dispositif segmente l'avant-plan à partir de l'arrière-plan de l'image. L'arrière-plan original est retiré et une image ou une vidéo d'arrière-plan stockée est mise en place en remplacement de l'arrière-plan original. L'arrière-plan remplacé est modifié en fonction de l'attitude et du mouvement du dispositif, lequel dispositif est détecté par un ou plusieurs capteurs placés dans le dispositif. Une partie de l'arrière-plan stocké choisi comme arrière-plan de substitution varie en fonction du mouvement du dispositif.
