Abstract

La présente invention concerne un dispositif d'affichage grâce auquel une image devant être visualisée sous la forme d'une image virtuelle peut être affichée de manière appropriée. Le dispositif d'affichage est installé dans un véhicule et émet une lumière d'affichage qui représente une image dans la direction vers un pare-brise de manière à afficher, sous la forme d'une image virtuelle V, l'image sur une surface virtuelle A qui est placée devant le pare-brise. Le dispositif d'affichage comprend un moyen de commande d'affichage qui commande l'affichage de l'image. La surface virtuelle A est placée de manière à être inclinée en direction de l'avant par rapport à la direction haut-bas à partir du point de vue d'un utilisateur qui visualise l'image. L'image comprend une image de contenu C prescrite et une image d'arrière-plan B qui sert d'arrière-plan de l'image de contenu C. L'image d'arrière-plan B est affichée avec une luminance plus élevée au niveau de la section supérieure par rapport à la section inférieure lorsqu'elle est vue depuis le point de vue de l'utilisateur. En outre, l'image d'arrière-plan B peut être affichée dans un mode de réalisation satisfaisant au moins l'un des éléments suivants : la section supérieure est d'une couleur plus chaude que la section inférieure, présente une saturation supérieure à celle de la section inférieure ou présente une luminosité plus élevée que celle de la section inférieure.
