ABSTRACT:
A photoelectric conversion device includes a first main electrode region of a first conductivity type; a second main electrode region of a first conductivity type; a control electrode region of a second conductivity type opposite to the first conductivity type serving as an accumulation region for carriers induced by an electromagnetic wave; a first circuit for setting the control electrode region selectively at a constant potential and at a floating state; and a second circuit for setting the first main electrode region selectively at a low impedance state and at a floating state; whereby the first and second circuits control the carrier removal, accumulation and readout operations in accordance with the selection conditions by the first and second circuits.
