Abstract

L'invention concerne un dispositif de commande d'affichage (14) qui a une unité d'évaluation (11) pour évaluer des informations, qui est un sujet d'affichage d'un affichage tête haute (HUD) (1), et une unité de génération d'image d'affichage (12) pour générer une pluralité d'images d'informations provenant d'une pluralité d'éléments d'informations évalués comme étant des sujets d'affichage par l'unité d'évaluation (11), et générer des images d'affichage agencées dans une rangée dans une direction de hauteur sur une image d'étage trapézoïdale. L'affichage d'une pluralité d'images d'informations, de façon à être superposées sur l'image d'étage, permet d'afficher une pluralité d'éléments d'informations concernant un corps mobile de telle sorte que les informations sont facilement visibles. L'agencement de la pluralité d'images d'informations dans une rangée dans la direction de hauteur de l'image d'étage trapézoïdale permet d'afficher une pluralité d'éléments d'informations de telle sorte que l'ordre de priorité des informations est facilement compris.
