Abstract: The present disclosure relates to an image sensor comprising an array of pixels arranged in first rows and in first columns. The pixels are arranged in groups of N*N pixels, with N an integer equal to or higher than 2. In each group, the pixels of the group are distributed into one or more sub-groups of a plurality of pixels. Each pixel comprises: a photosensitive element, a first node coupled to the photosensitive element, a second node common to all pixels of a same sub-group, and coupled to a first potential, a first transistor coupling the first and second nodes to each other, a second source-follower transistor having a gate connected to the first node, and a third transistor coupling the source of the third transistor to a reading line.
