Claim:
1. A control method for a photosensitive device comprising a matrix of pixels distributed at the intersections of rows and columns of the matrix, each of the pixels comprising a photosensitive element able to generate an electrical signal under the effect of incident radiation and a selector switch controlled by a row conductor, the selector switch allowing the photosensitive element to be connected to a column conductor, the device further comprising a readout circuit connected to the column conductor to read out successively the various pixels connected to the column conductor, the method leading each of the pixels to activate the selector switch for said pixel a first time by deactivating the associated readout circuit and to activate the selector switch for said pixel a second time by activating the associated readout circuit, the duration separating the first activation and the second activation of the selector switch being equal to a predefined duration of integration, wherein the second activation of the selector switch occurs during a readout phase of a given first pixel row to which the selector switch in question belongs, and wherein the first activation of the selector switch of pixels of the given first row occurs during a readout phase of a second pixel row distinct from the first pixel row.
