Abstract
There is provided an image pickup apparatus including a plurality of pixels each including a photoelectric conversion unit which converts incident light into an electrical signal and accumulates the electrical signal, an amplifier transistor which amplifies and outputs the signal from the photoelectric conversion unit, a transfer transistor which transfers the electrical signal accumulated in the photoelectric conversion unit to the amplifier transistor, and a processing transistor which performs predetermined processing, and a control circuit which sets the signal level supplied to the control electrode of the transfer transistor in order to turn off the transfer transistor to be lower than the signal level supplied to the control electrode of the processing transistor in order to turn off the processing transistor.
