To prevent smear caused by the sun beam incident directly onto a CCD.

A transparent liquid crystal display element 15 is placed in front of a CCD built in a video camera, a coordinate of the sun beam transmitted through a display screen of the transparent liquid crystal display element 15 is calculated based on map information outputted from a navigation system 22 and date and time information outputted from a clock/calendar circuit 23, a pixel at a position of the display screen of the transparent liquid crystal display element 15 corresponding to the coordinate is driven to display a mask and the mask shuts the sun beam made incident onto the CCD.
