Abstract:
1. An imaging system comprising: a plurality of pixels, each including: 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; and a control circuit for switching a reset voltage supplied through the reset switch in accordance with a sensitivity set in the imaging system, wherein the control circuit sets a first reset voltage when the set sensitivity is higher than or equal to a predetermined value and sets a second reset voltage, which is higher than the first reset voltage, when the set sensitivity is lower than the predetermined value.
