Title
(EN) DISPLAY APPARATUS AND CONTROL METHOD THEREOF
(FR) APPAREIL D'AFFICHAGE ET PROCÉDÉ DE COMMANDE ASSOCIÉ
Abstract
(EN)
A display apparatus includes a display; an optical sensor; and a processor configured to: obtain a current illumination value detected by the optical sensor while the display displays an image, identify a first illumination level corresponding to the obtained current illumination value, the first illumination level being previously obtained at a time when the display is displaying a preset image, identify an ambient brightness based on a second illumination level, the second illumination level corresponding to the identified first illumination level and being previously obtained at a time when the display is not displaying any image, and perform an operation based on the identified ambient brightness.
(FR)
L'invention concerne un appareil d'affichage comprenant : un dispositif d'affichage; un capteur optique; et un processeur configuré pour : obtenir une valeur d'éclairage actuelle détectée par le capteur optique tandis que le dispositif d'affichage affiche une image; identifier un premier niveau d'éclairage correspondant à la valeur d'éclairage actuelle obtenue, le premier niveau d'éclairage étant préalablement obtenu à un moment où le dispositif d'affichage affiche une image prédéfinie; identifier une luminosité ambiante d'après un second niveau d'éclairage, le second niveau d'éclairage correspondant au premier niveau d'éclairage identifié et étant préalablement obtenu à un moment où le dispositif d'affichage n'affiche aucune image; et effectuer une opération d'après la luminosité ambiante identifiée.
