Abstract:
1. An image sensor comprising a matrix of photosensitive elements, with, in the region where each row and each column of the matrix cross, a pixel comprising: a photosensitive region (N an n-type storage region (N a first transfer gate (G a second transfer gate (G a third transfer gate (G a first follower MOS transistor (T a second MOS transistor (T the sensor further including a first row conductor (SEL) connected to the second and fifth transfer gates of all of the pixels of one row, wherein the second transistor is rendered conductive whenever the fifth transfer gate authorizes said transfer of charges from the photosensitive region to said supply conductor, a second row conductor (RESET) connected to the third transfer gate of all the pixels of said row, and a third conductor (TRA) connected to the first transfer gate of all the pixels of the matrix.
