ABSTRACT:
The disclosure concerns matrices of photosensitive elements. To prevent the need for a resetting light source in matrices using, as a photosensitive dot, a photodiode in series with a capacitor between a row conductor and a column conductor, a photosensitive dot is proposed, formed by a photodiode in series with a reading diode between a row conductor and a column conductor, it being possible to put the reading diode into forward or reverse conduction. To read the photoelectrical charges generated, a reading pulse, which makes the reading diode forward conductive, is applied. To then reset the potential of the floating node A, at which the photoelectrical charges accumulate, at a constant starting level, a reverse resetting pulse is applied, thus making the reading diode conductive (but this time in reverse conduction).
