Abstract
A pixel is configured to output a signal. An input node is configured to input the signal. A holding circuit is configured to hold the signal input to the input node. An amplifier is configured to input the signal held in the holding circuit. An output node is configured to output the signal from the amplifier. An input switch is connected in series between the input node and the holding circuit. An output switch is connected in series between the amplifier and the output node. In a first operation mode, the output switch is in an on state, and the input switch is turned on or off at a predetermined timing to hold the signal in the holding circuit. In a second operation mode, the input switch and the output switch are an off state and the amplifier outputs a constant voltage.
