Abstract
An embodiment light sensor includes an array of pixels arranged in rows and in columns. Each pixel comprises a photodiode, a sense node coupled to the photodiode, and an initialization transistor connected to the sense node. N successive pixels of a column or of a row are associated, where N is greater than or equal to 2. The initialization transistor of a first one of the pixels arranged at one end of the association of the N pixels is connected between the sense node of the first one of the pixels and a node of application of an initialization potential. For each two successive pixels among the N pixels, the initialization transistor of one of the pixels that is the most distant from the end is connected between the sense nodes of the two pixels.
