Abstract

La présente invention concerne un procédé et un dispositif de réglage d'affichage d'écran. Le procédé consiste à : déterminer si l'écran se trouve dans un état de travail et, si c'est le cas, démarrer un appareil de prise de vues orienté vers l'avant afin de capturer une image ; lorsqu'il est déterminé qu'un visage humain est présent dans l'image capturée, obtenir une valeur de distance de caractéristique faciale dans l'image ; et, lorsqu'il est déterminé que la valeur de distance de caractéristique faciale est supérieure ou égale à un seuil maximal prédéfini, réduire la luminance et/ou la transparence de l'écran. Au moyen de la solution selon la présente invention, la luminance et/ou la transparence de l'écran sont réglées en fonction de la valeur de distance de caractéristique faciale et, par conséquent, un réglage automatique et à temps de l'affichage d'écran est mis en œuvre. Du fait que la valeur de distance de caractéristique faciale reflète indirectement la distance entre le visage humain et l'écran, la solution selon la présente invention exerce une influence subtile sur des personnalisations de l'utilisateur et protège la vue de l'utilisateur.
