Abstract

L'invention concerne un téléphone mobile de type pliant ou de type coulissant possédant un processeur d'image dans sa partie pliante supérieure, ce processeur d'image étant installé dans la partie pliante supérieure ou, de préférence, dans un module LCD, alors que la partie pliante inférieure comprend une partie de commande, laquelle comprime les données à transmettre au module LCD. Le processeur d'image décomprime les données comprimées, puis les transmet au LCD. Si une caméra est installée dans la partie pliante supérieure, la sortie de la caméra est directement reliée au processeur d'image dans la partie pliante supérieure. Si les données d'image de la caméra sont également comprimées par le processeur d'image avant sa transmission à la partie de commande dans la partie pliante inférieure, une réduction sensible de la quantité de données à transmettre entre la partie pliante supérieure et la partie pliante inférieure peut être réalisée.
