Abstract

La présente invention concerne un terminal mobile qui comprend un module de traitement d'image, un module de stockage, un premier port de transmission de données et un module de commande de prise de vues connectés les uns aux autres de manière à communiquer entre eux. Le module de commande de prise de vues est configuré pour commander, lors de la détection d'une caméra additionnelle connectée à un terminal mobile, la caméra additionnelle sur la base d'une commande de prises de vues afin de recueillir des données d'image brutes avec des paramètres de prise de vue correspondant à la commande de prises de vues. Le premier port de transmission de données est configuré pour recevoir les données d'image brutes transmises par la caméra additionnelle et transmettre les données d'image brutes au module de traitement d'image. Le module de traitement d'image est configuré pour réaliser un processus correspondant sur les données d'image brutes sur la base d'une instruction de traitement d'image reçue. Le module de stockage est configuré pour stocker les données d'image brutes traitées par le module de traitement d'image. La solution décrite ci-dessus permet à une caméra additionnelle d'être légère et facile à monter et à transporter, ce qui permet un ajustement et une utilisation plus pratique de la caméra additionnelle avec un terminal mobile.
