Abstract

PURPOSE:To photograph both a number plate and a driver of a car with high contrast, by providing a filter that reduces the light reflected from the number plate on an optical axis formed by connecting the film of a camera and the car. CONSTITUTION:A filter 13 is provided to a known and conventional constitution to reduce the reflected light 15 given from a number plate 14. When a car 1 is photographed, the light 15 entering a camera 4 from the plate 14 is reduced by a filter 13 and in front of a film 7. While the light entering the film 7 from the areas except the plate 14 is not reduced. Then the transmission factor of the filter 13 is selected, and a sufficient amount of light illuminated from a strobe 9 is irradiated to the car 1. As a result, both the driver within a driver seat and the plate 14 can be photo graphed with no overexposure and high contrast.
