A processor includes a comparison section for comparing an output (dimming signal) of a dimmer circuit and a predetermined reference value, a setting section for setting a gain of an AGC, a shutter control parameter (charge storage time) in an electronic shutter control section, and an opening area of a light source diaphragm in a light source device based on a comparison result of the comparison section, and the electronic shutter control section for controlling an electronic shutter function of a CCD driving circuit under control of the setting section.
