The invention relates to a method for controlling a light-sensitive device comprising a matrix of light-sensitive points arranged into lines and columns. The invention can essentially but not exclusively be used in light-sensitive devices used for detecting X-ray images. The method includes a step (E) of acquiring an image during which each light-sensitive point can accumulate a charge, and a step (E) of reading said image. The reading step (E) comprises a preliminary sub-step (E) of converting the charges accumulated at the different light-sensitive points into analog signals representative of said charges, and a sub-step (E) of processing the analog signals in order to obtain a digital image. According to the invention, the processing sub-step (E) is repeated N times for a same light-sensitive point and for a same acquisition step (E), with N being an integer greater than or equal to two, and the reading step (E) comprises a sub-step (E) of averaging the N signals processed per light-sensitive points in order to provide a single digital image per acquisition step (E).
