Abstract

La présente invention concerne un terminal mobile apte à capturer une image et plus particulièrement, un terminal mobile dans lequel la taille d'une image d'un sujet affiché sur une unité d'affichage du terminal mobile est fixe même lorsque la distance entre le terminal mobile et le sujet change, et un procédé de commande dudit terminal mobile. La présente invention concerne un terminal mobile comprenant : une caméra servant à capturer une image comportant un sujet ; une unité d'affichage servant à afficher l'image capturée ; et une unité de commande, l'unité de commande établissant le sujet dans l'image capturée et effectuant un réglage de zoom optique par l'intermédiaire du réglage d'une longueur focale de la caméra et/ou un réglage de zoom numérique de l'image capturée afin de régler le grossissement de l'image capturée lorsque la distance entre le terminal mobile et le sujet change, ce qui permet de commander la taille du sujet établi de manière à ce qu'elle apparaisse constante. Ainsi, la présente invention peut fournir un terminal mobile apte à capturer le sujet à une taille constante même lorsque la distance entre le terminal mobile et le sujet change, et à appliquer un effet de "travelling contrarié" également connu sous le nom d'effet Hitchcock.
