Abstract
A sense circuit includes a differential amplifier circuit including an inverting input section, a non-inverting input section and an output section, an electrical capacitor connected between the inverting input section and the output section, and a field effect transistor including a source, a drain, and a gate. One of the source and the drain is connected to the inverting input section, and the other of the source and the drain is connected to the output section. A reference potential is supplied to the non-inverting input section, and an output section of a photoelectric conversion cell having an added switching function is connected to the inverting input section.
