<p>The invention relates to an image sensor, comprising a group of photosites (Kx L) and an analog/digital converter, each photosite being capable of receiving a luminous flux and of emitting an electric signal, in analog format, thus powering the converter. In particular, the sensor further comprises, upstream of the converter: -a plurality of circuit integrators, each circuit integrator being connected to a group of photosites forming a neighborhood, each circuit integrator being capable of emitting an analog signal corresponding to an average (V0) of the analog signals emitted by the photosites from the neighborhood, and -regulating methods to adjust (F(Vph, V0)) the analog signal from each photosite (Vph) using the average signal for the neighborhood of the photosite.</p> |
