Abstract

L'invention concerne un dispositif de commande d'affichage (1000) qui comporte : une unité de traitement d'image (1140) permettant de générer un signal d'image pour une image d'affichage; une unité d'affichage d'image (1200) permettant d'acquérir le signal d'image pour l'image d'affichage générée par l'unité de traitement d'image et de projeter de la lumière d'affichage d'image de l'image d'affichage sur une unité optique dans laquelle une première surface de montage ou une seconde surface de montage faisant face à la première surface de montage peuvent être montées sur un organe de montage; et une unité d'acceptation d'opération (1170) permettant d'accepter une opération d'entrée de direction d'un utilisateur. L'unité de traitement d'image (1140) génère une image de définition d'orientation verticale contenant une première image montrant une première alternative et une seconde image montrant une seconde alternative orientée verticalement à l'inverse de la première image, et génère par commutation de manière alternée une première image de définition d'orientation verticale montrant un état dans lequel la première alternative peut être sélectionnée et une seconde image de définition d'orientation verticale montrant un état dans lequel la seconde alternative peut être sélectionnée.
