Abstract: An image pickup apparatus of the present invention includes a clipping circuit that clips the voltage of an input node of an amplifying unit in a pixel. The clipping circuit can operate at least in a time period in which a charge is transferred from a photoelectric conversion unit to the input node of the amplifying unit, and can switch among multiple clipping voltages.
