Abstract

Capteur d'image et son procédé de commande La présente description concerne un capteur comprenant des pixels (1) comportant chacun :un premier transistor (118) et un premier interrupteur (120) en série entre un premier noeud (124) et un noeud (122) interne du pixel, une grille du premier transistor (118) étant couplée à un deuxième noeud (106) ;un élément capacitif (110) dont une première borne est connectée au deuxième noeud ; et plusieurs ensembles (A, B) comprenant chacun une capacité (128) en série avec un deuxième interrupteur (130) connecté au noeud interne, le capteur comprenant un circuit (150) configuré pour, lors de chaque mémorisation d'une tension dans un des ensembles (A, B), commander l'interruption d'un courant entre le premier noeud (124) et le noeud interne (122) :en commutant un premier potentiel (Vech) appliqué à une deuxième borne (112) de l'élément capacitif ; ou en ouvrant le premier interrupteur (120).
