Abstract
In order to modulate the sensitivity of a photosensitive device by modulating the integration time, a first reading of each line of a photosensitive zone of the device is followed by a second reading at an adjustable time interval. The charges resulting from the first reading operation are removed to the drain while the parasitic charges and the signal charges resulting from the second reading operation are transferred to the read register at the same time. Modulation of the time interval which elapses between two readings of one line is carried out by varying the time which elapses between the injection of one drive pulse into the two registers which control respectively the first reading and the second reading of the lines.
