摘要： A photoelectric converter includes a first pn junction comprised of at least two semiconductor regions of different conductivity types, and a first field-effect transistor including a first source connected with one of the semiconductor regions, a first drain, a first insulated gate and a same conductivity type channel as that of the one of the semiconductor regions. The first drain is supplied with a second potential at which the first pn junction becomes zero-biased or reverse-biased relative to a potential of the other of the semiconductor regions. When the first source turns to a first potential and the one of the semiconductor regions becomes zero-biased or reverse-biased relative to the other semiconductor regions, the first pn junction is controlled not to be biased by a deep forward voltage by supplying a first gate potential to the first insulated gate, even when either of the semiconductor regions is exposed to light.
