摘要:
An image pickup apparatus includes a plurality of sensor cells each including a photoelectric conversion element, an amplifier transistor which amplifies and outputs a signal from the photoelectric conversion element, and a selector transistor for selectively outputting a signal from the amplifier transistor, and a driving circuit which supplies a predetermined voltage to the transistor so as to change the amplifier transistor to an OFF state or an accumulation state before the amplifier transistor outputs a signal generated in the photoelectric conversion element.
