In a solid-state image pickup device of the type in which a photosensitive or photoconductive film is formed over a substrate capable of charge-transfer or X-Y address scanning and an electrode is formed over the photosensitive or photoconductive film, a means for applying to the electrode a voltage having an amplitude proportional to the amount of incident light, whereby blooming may be minimized and an automatic aperture control function may be attained. Because the voltage applied to the electrode over the photosensitive or photoconductive film is set so that the sensitivity of the photoconductive film may be decreased when a light image of high intensity falls on the device, blooming may be avoided.
A solid-state image pickup device characterized by the provision of
