Abstract
A plurality of pixel circuits are arranged in a row direction and a column direction. Each of the pixel circuits includes a photoelectric conversion circuit for light from a subject. Signal charge of the photoelectric conversion circuit is transferred to a charge holding circuit and is discharged via an overflow gate (OFG). A signal processing substrate includes a plurality of signal holding circuits for the plurality of pixel circuits. The signal holding circuit includes a holding capacity circuit that holds a voltage signal or signal charge transferred from the charge holding circuit. Driving for converting signals of the holding capacity circuit into digital signals in a row-sequential manner and outputting the digital signals is performed in a period of intermittent charge accumulation in which transfer and discharge of charge from the photoelectric conversion circuit to the charge holding circuit are alternately performed.
