Patent ID: 7030922

Claim:
An image pickup apparatus comprising: a plurality of sensor cells each including a photoelectric conversion element, an amplifier transistor which amplifies and outputs a signal from said photoelectric conversion element, and a selector transistor for selectively outputting a signal from said amplifier transistor; and a driving circuit which supplies a predetermined voltage to said amplifier transistor so as to change said amplifier transistor to an OFF state or an accumulation state before said amplifier transistor outputs a signal generated in said photoelectric conversion element, wherein said image pickup apparatus further comprises a common output line which is commonly connected to said plurality of sensor cells and receives signals from said plurality of sensor cells, and a switching transistor for supplying the predetermined voltage to said sensor cells, wherein said driving circuit supplies the predetermined voltage to said amplifier transistor so as to change said amplifier transistor to the OFF state or the accumulation state via said switching transistor.
