In addition, since the position of the second information 22 is a position with the vehicle body portion of the vehicle 50 as a background, even if the color and display brightness of the second information 22 are increased, the driver's view is obstructed. There is no.
  • the image display device according to the present embodiment can be used as an image display device implemented in a passenger car, for example.

Abstract

Ce dispositif d'affichage d'image pour un véhicule (1) comprend un dispositif d'obtention de données vidéo (5), un projecteur (3) et un dispositif de commande de projection (4). Le dispositif d'obtention de données vidéo (5) obtient des données vidéo dans lesquelles des premières informations d'importance relativement faible lorsque le véhicule se déplace et des secondes informations d'importance relativement élevée lorsque le véhicule se déplace sont combinées. Le projecteur (3) projette des données vidéo en tant qu'éclairage vidéo. Le dispositif de commande de projection (4) commande le projecteur (3). Le dispositif de commande de projection (4) commande le projecteur (3) de sorte que le conducteur du véhicule reconnaît visuellement que les premières informations sont affichées, avec une première scène ayant un degré de changement relativement élevé lorsque le véhicule se déplace, comme arrière-plan parmi des scènes visualisées par le conducteur du véhicule, et que les secondes informations sont affichées, avec une seconde scène ayant un degré de changement relativement faible lorsque le véhicule se déplace, comme arrière-plan parmi les scènes visualisées par le conducteur du véhicule.
