ABSTRACT:
A lower electrode, a photoelectric conversion layer, and an upper electrode are stacked in order above a semiconductor substrate, and a charge storage section that stores charge generated in the photoelectric conversion layer is connected to the lower electrode. The charge stored in the charge storage section is swept away by a charge sweeping away section for a given time from the endpoint of exposure. The given time is a time taken until the residual image charge existing in the photoelectric conversion layer at the exposure end point time is sufficiently discharged to the outside of the photoelectric conversion layer in a state in which the same bias as that at the exposure start time point is applied to the photoelectric conversion layer.
