ABSTRACT:
An amplifier type solid-state imaging device is operated in a capacitor load operation system. This solid-state imaging device is made high in reliability and an arrangement of the horizontal output circuit portion is simplified. The solid-state imaging device includes a plurality of pixel MOS transistors each of which is connected between a voltage source (V.sub.DD) and a vertical signal line, a control electrode thereof being connected to a scanning line and charges generated by photoelectric conversion being accumulated near the channel thereof, a load capacitor element connected between the vertical signal line and a first potential, and a reset MOS switch for resetting the load capacitor element to a reset potential. When a signal is read out, the potential of the load capacitor element is set to substantially the same potential as the channel potential of the pixel MOS transistor. The capacitance of the load capacitor element is set to be larger than the capacitance of the vertical signal line.
