Abstract
The present invention relates to a photosensitive element (1) for detecting flashes of light (2). According to the invention, said photosensitive element (1) includes a control device (4) knowing the instant of the emission of the flashes of light (2) and capable of switching said photosensitive element into one or the other of two different states: PA0 a positive accumulation state in which the accumulation capacitor (12) is charged by the light energy from said photosensitive element (1); and PA0 a negative accumulation state in which the accumulation capacitor (12) is discharged by the light energy from said photosensitive element (1).
