Title
(EN) METHOD AND APPARATUS FOR LIMITING STORAGE OR TRANSMISSION OF VISUAL INFORMATION
(FR) PROCEDE ET APPAREIL DESTINES A LIMITER LE STOCKAGE OU LA TRANSMISSION D'INFORMATIONS VISUELLES
Abstract
(EN)
A method carried out at a transmitter (800), of limiting visual information that can be stored or transmitted captures a visual image (608). Whenever a control signal is detected (612) at the transmitter (800), at least a portion of the visual image is obscured (616) to produce an obscured visual image. This obscured image is then stored and/or transmitted (620). The image can be obscured by any number of techniques including replacement of the image with a substitute (718), blurring, distorting or reducing the resolution of the background (738), substitution of backgrounds (762) or removal of the background (778).
(FR)
La présente invention concerne un procédé mis en oeuvre au niveau d'un émetteur (800), limitant des informations visuelles qui peuvent être des captures d'image visuelle (608) stockées ou transmises. Chaque fois qu'un signal de commande est détecté (612) au niveau de l'émetteur (800), au moins une partie de l'image visuelle est obscurcie (616) de façon à produire une image visuelle obscurcie. Cette image obscurcie est ensuite stockée et/ou transmise (620). Cette image peut être obscurcie par un certain nombre de techniques comprenant le remplacement de l'image avec un substitut (718), l'allongement du point, la distorsion ou la réduction de la résolution du fond (738), la substitution de fonds (762) ou la suppression du fond (778).
