ABSTRACT:
An imaging system includes a plurality of pixels and a control circuit. Each pixel includes a photoelectric transducer converting an optical signal into signal charge, a charge transfer device transferring the signal charge converted by the photoelectric transducer, an amplifying device amplifying the signal charge transferred from the photoelectric transducer by the charge transfer device and outputting the amplified signal charge to an output line, and a reset switch used for resetting the voltage of an input terminal of the amplifying device. The control circuit switches a reset voltage supplied through the reset switch in accordance with a sensitivity set in the imaging system.
