Abstract

An imaging device including: a photoelectric converter that generates signal charge; a charge storage region that stores the signal charge; a first transistor that has a gate coupled to the charge storage region and reads out the signal charge; a second transistor that, has a source and a drain, an output of the first transistor being fed back to one of the source and the drain and being supplied to the charge storage region from the other of the source and the drain; and voltage supply circuitry that supplies voltages varying with time. In a reset operation for discharging the signal charge stored in the charge storage region, the voltage supply circuitry supplies the voltages to a gate of the second transistor so that the second transistor gradually changes from an OFF state to an ON state.
