ABSTRACT:
A signal charge in an amplifying type solid-state imaging device of a capacitor load charge system can be detected efficiently. The amplifying type solid-state imaging device is composed of a plurality of pixel transistors, a load capacitor for accumulating signal charges of an amount corresponding to light incident on the pixel transistor, an operational amplifier having a first input terminal connected with the load capacitor element and a second input terminal to which a bias voltage is applied, a detection capacitor element connected in parallel to the operational amplifier and a reset switch (33) for resetting the detection capacitor element.
