Abstract

Méthode permettant de rajuster automatiquement la luminosité de l'affichage d'un dispositif électronique mobile doté d'un détecteur de lumière, d'un écran d'affichage et d'un capteur d'orientation, ladite méthode faisant en sorte que l'affichage soit lisible lorsque le dispositif se trouve dans diverses conditions d'éclairage et orientations. La méthode comprend l'obtention d'échantillons de niveau de lumière par le capteur de lumière et de l'orientation par le capteur d'orientation et le rajustement de l'intensité de lumière de fond de l'affichage en réponse aux échantillons de niveau de lumière et à l'orientation du dispositif. Préférablement, les rajustements de lumière de fond sont faits pour varier de faible à brillant, sans égard à l'orientation du dispositif, tandis que les rajustements de brillant à faible sont faits uniquement pour des orientations du dispositif selon lesquelles il est peu probable que le capteur de lumière soit couvert.
