Abstract

L'invention concerne un procédé et un appareil de collecte d'images, un terminal mobile et un support d'informations. Le procédé comprend les étapes consistant : lorsqu'il est détecté qu'un appareil photo est démarré, à afficher, sur un premier écran, une image collectée en temps réel par l'appareil photo ; lorsqu'une instruction de photographie est détectée, à activer un second écran de sorte qu'il réalise un affichage à une luminosité prédéfinie ; et à stocker les images collectées par l'appareil photo lorsque le second écran réalise l'affichage à la luminosité prédéfinie. Le procédé permet d'obtenir une application de lumière par réalisation d'un affichage, par le second écran, à la luminosité prédéfinie, ce qui permet d'éviter le problème de mauvaise qualité d'une photographie photographiée en raison d'une lumière excessivement forte provenant d'un flash.
