Abstract

La présente invention concerne un dispositif de traitement de signaux (100) comprenant les éléments suivants : une unité de stockage de signal de commande (101) qui stocke des signaux de commande d'entrée indiquant un type d'image parmi plusieurs types d'images, y compris 2D et 3D ; une unité de détermination de signal de commande (120) qui détermine, pour une certaine durée après que le type d'image a été changé, que l'image est revenue au type d'image original ; une unité de conversion de signal de commande (130) qui, si la détermination susmentionnée a été réalisée, convertit un signal de commande d'entrée en une période de changement et l'émet en qualité de signal de commande de sortie ; et une unité de conversion de signal d'image (140) qui, lorsque le signal de commande d'entrée et le signal de commande de sortie sont différents, convertit le signal d'image d'entrée et émet un signal d'image de sortie.
