Abstract

Capteur d'images intégré (DIS) adapté à un mode de commande dit à obturation globale comportant une matrice de pixels dans laquelle chaque pixel (PX) comporte une première partie de circuit (P1) apte à intégrer et stocker à l'abri de la lumière des électrons issus d'une illumination (LX) de la matrice de façon à former un premier signal, une deuxième partie de circuit (P2) apte à intégrer les trous issus de ladite illumination (LX) de façon à former un deuxième signal et apte à stocker le deuxième signal à l'abri de la lumière, et une troisième partie de circuit (P3) apte à lire le premier signal et le deuxième signal, et apte à réaliser des opérations de combinaisons entre le premier signal et le deuxième signal afin de générer un signal combiné, l'ensemble des signaux combinés étant destiné à former une image.
