Abstract

L'invention concerne un dispositif d'affichage tête haute (HUD) qui est capable de faire en sorte qu'un téléspectateur reconnaisse de manière plus fiable les informations acquises. Ce dispositif HUD 100 émet une lumière d'affichage vers un pare-brise pour afficher une image virtuelle superposée sur un paysage réel qui peut être vu à travers le pare-brise. Le dispositif HUD 100 comprend: un dispositif d'affichage qui émet la lumière d'affichage; une unité d'analyse d'images 171 et une unité d'acquisition d'informations de communication 174 qui acquièrent des informations de détection I1 et des informations de communication I2 associées à un autre véhicule 400 présent dans l'environnement d'un véhicule hôte 300; et une unité de génération d'images 172 qui génère une image d'informations en tant qu'image virtuelle. L'unité de génération d'images 172 modifie le mode d'affichage de l'image d'information en fonction du type, du nombre de pièces ou de la combinaison des informations de détection I1 et des informations de communication I2 qui ont été acquises.
