Abstract: A solid-state imaging apparatus has: a signal readout circuit including a charge storage region connected to a photoelectric conversion region, and a reset transistor connected at one of source and drain to the charge storage region; and a negative feedback circuit that feeds back an output of the signal readout circuit in a negative feedback manner to the other of the source and drain of the reset transistor. A reset operation for discharging a charge stored in the charge storage region includes a first period in which the negative feedback circuit is OFF and a second period which occurs after the first period and in which the negative feedback circuit is ON. In the first period, the reset transistor changes from OFF to ON and then to OFF. In the second period, such a reset transistor control voltage is applied that makes the reset transistor to gradually change to ON.
