Abstract
A selection pixel where signal readout is performed and a reference pixel where signal readout is not performed are arranged in a pixel array section, and an amplification transistor of the selection pixel and an amplification transistor of the reference pixel each source electrode of which is connected in common to a common wire are connected with a constant current source via the common wire to form a differential amplification circuit. Then, a bypass control section which selectively establishes connection between the constant current source and a differential output node of the differential amplification circuit and limits a voltage of the differential output node to a predetermined voltage by causing a bypass current to flow between the constant current source and the differential output node, and a current path for bypass current that supplies the bypass current to the constant current source through the pixel array section are included.
