Abstract
La présente description concerne un capteur d'images à semiconducteur. Chaque pixel du capteur comprend un substrat semiconducteur (10) ayant des faces avant et arrière opposées et délimité latéralement par un premier mur d'isolement (11) comprenant un premier coeur conducteur (12) isolé du substrat, des paires électrons-trous étant susceptibles de se former dans le substrat par suite d'un éclairement par la face arrière. Un circuit est configuré pour maintenir, pendant une première phase dans un premier mode de fonctionnement, le premier coeur conducteur à un premier potentiel et pour maintenir, pendant au moins une partie de la première phase dans un deuxième mode de fonctionnement, le premier coeur conducteur à un deuxième potentiel différent du premier potentiel.
