ABSTRACT:
A control device includes a control mechanism for eliminating a dark current effect generated in a CCD. The control mechanism carries out a charge pumping operation in the CCD during a time after an object is photographed up until the time when an aperture is closed. The control mechanism obtains a dark current component generated when the aperture is closed after a photographing operation, based on a dark current component outputted by the CCD during a predetermined period, and then subtracts the dark current component from data outputted by the CCD in accordance with an image signal corresponding to the subject.
