Abstract
The level of smear charge stored in a CCD is calculated. If the smear level is equal to or greater than a predetermined threshold value, exposure is performed using a mechanical shutter in order to suppress smear. If the smear level is less than the threshold value, exposure is controlled utilizing an electronic shutter. Power consumption owing to drive of the mechanical shutter can be reduced while occurrence of smear is suppressed.
