Abstract

La présente invention concerne un procédé pour régler un menu de fonction, consistant : lorsqu'une instruction d'affichage de menu de fonction est détectée, à déterminer si un mode de plage dynamique élevée (HDR) est ou non actuellement activé; si le mode de plage dynamique élevée (HDR) est activé, à diviser, dans une direction horizontale et dans une direction verticale, une trame courante en régions égales; à déterminer les types de trames des régions; et lorsque toutes les régions sont des régions de trame sombres, à calculer une valeur de moyenne de valeurs de pixel auxquelles les points de pixel dans les régions de trame sombres correspondent, de façon à obtenir une première valeur de moyenne, et à régler des valeurs de pixel d'arrière-plan du menu de fonction auxquelles les régions de trame sombres correspondent en la première valeur de moyenne. La présente invention concerne également un dispositif pour régler un menu de fonction. La présente invention résout le problème de la faible transparence des détails de programme de restitution de menu de fonction d'une trame noire HDR couverte par le menu de fonction.
