Abstract

La présente invention concerne un dispositif électronique contenant un terminal mobile et un boîtier auquel le terminal mobile est couplé, ainsi qu'un procédé de commande de celui-ci. En connexion avec le dispositif électronique selon la présente invention, le terminal mobile comprend : un corps de terminal couplé au boîtier ; de multiples caméras disposées sur les surfaces avant et arrière du corps de terminal, respectivement ; et une première unité d'affichage couplée au boîtier. Le boîtier comprend : un premier corps formé de manière à contenir au moins une partie du corps de terminal ; un deuxième corps sur lequel est disposé un deuxième affichage ; une unité de liaison disposée entre le premier et le deuxième corps de façon à coupler le premier et le deuxième corps afin que ceux-ci puissent tourner l'un par rapport à l'autre ; et une unité de câblage connectant électriquement le premier et le deuxième corps, l'unité de câblage étant formée pour délivrer des données reçues du terminal mobile à la deuxième unité d'affichage. Pendant qu'un premier écran de prévisualisation est affiché sur la première unité d'affichage selon le pilotage de la caméra arrière du corps de terminal, une unité de commande commute le pilotage de la caméra arrière pour piloter la caméra avant en réponse à une rotation relative effectuée par le premier et le deuxième corps de façon à atteindre un état de retournement dans lequel la surface arrière du deuxième corps recouvre la surface arrière du corps avant, et commande un deuxième écran de prévisualisation correspondant au pilotage de la caméra avant de façon à ce qu'il soit affiché sur la première unité d'affichage.
