Abstract

La présente invention concerne un dispositif de commande, qui commande l'affichage d'une image à afficher à une position où l'image chevauche un environnement à l'extérieur d'un corps mobile du point de vue d'un occupant du corps mobile. Dans le dispositif de commande, une partie d'affichage change entre un premier cas et un second cas en fonction de la luminosité à l'extérieur du corps mobile. Dans le premier cas, au moins une partie de l'image est affichée avec une première luminosité et dans un premier mode d'affichage, et dans le second cas, au moins une partie de l'image est affichée avec une seconde luminosité et dans un second mode d'affichage.
