CA 2643724

A navigation device is configured to allocate display setting such as color schemes and screen contents to at least one ambient lighting condition, monitors and evaluates a signal indicative of ambient lighting conditions and determines whether display settings for the current ambient lighting conditions are already in use and to change display settings so that they suit current ambient lighting conditions if needed.

L'invention concerne un dispositif de navigation conçu pour attribuer des paramètres d'affichage, par exemple des combinaisons de couleurs et des contenus d'écran, à au moins une condition d'éclairage ambiant. Ledit dispositif surveille et évalue un signal indiquant les conditions d'éclairage ambiants et détermine si des paramètres d'affichage pour les conditions d'éclairage ambiant actuelles sont déjà utilisés, ledit dispositif étant également conçu pour changer les paramètres d'affichage de manière à adapter ceux-ci aux conditions d'éclairage ambiant actuelles si nécessaire.
