Abstract

PURPOSE:To suppress the reduce of amount of signal charge by supplying signal charge from a source provided in a unit cell without using charge obtained from photoelectrical conversion made by incident light as the signal charge. CONSTITUTION:When an optical image is projected on a device, a photoconductive film causes polarization according to its light intensity distribution and the potential of a metallic electrode rises to form a channel near the insulating film interface of a semiconductor substrate. Then, when a transfer electrode 18 is turned on, charge which corresponds to the polarization of the photoconductive film is transferred to a vertical-transfer-charge transfer element 16. As well as the operation of an interline type charge transfer element area sensor, the signal charge is transferred through the charge transfer element 16 and a horizontal-transfer-charge transfer element 20 successively and then amplified by an output transistor 21. At this time, after the charge is transferred to the charge transfer element 16, the potential of a transparent electrode is held negative for a certain time to depolarize the photoconductive film.
