ABSTRACT:
An apparatus, which drives an imaging device of a full frame transfer type, comprises an accumulating period calculating processor and a voltage control processor. In the imaging device, a light receiving element and a vertical transfer passage are common. The accumulating period calculating processor obtains an accumulating period, for which a signal charge is accumulated in the light receiving element, by a calculation. The light receiving element is provided with first and second electrodes to which voltages are applied. During the accumulating period, the voltage control processor fixes a voltage level of the first electrode and changes periodically a voltage level of the second electrode in accordance with a length of the accumulating period, so that a charge pumping operation is performed.
