A processor is provided with a power supply circuit for supplying voltages of different values to a CCD. A RAM of the processor stores a power control information table in which types of the CCD and power control information indicating methods of supplying each voltage to the CCD are related and stored. A CPU retrieves CCD information indicating the type of the CCD from a ROM and identifies the type of the CCD. The CPU then retrieves the power control information corresponding to the identified type from the power control information table. Based on the power control information, the CPU controls the power supply circuit to supply voltages of different values to the CCD in a sequence and at an interval corresponding to the type of the CCD.
