Abstract: An imaging device includes a photoelectric converter generating signal charge; a charge storage region storing the signal charge; a first transistor having a gate coupled to the charge storage region; a second transistor having a source and a drain; and voltage supply circuity supplying voltages varying with time. An output of the first transistor is fed back to the second transistor and is supplied to the charge storage region. A reset operation for discharging the signal charge in the charge storage region includes a first reset operation and a second reset operation. In the first reset operation, the second transistor changes from an OFF state to an ON state and then changes to an OFF state. In the second reset operation, the voltage supply circuity 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.
