PURPOSE:To eliminate adverse influence such as light mottling by specular reflected light by photographing two kinds of image by both means of projecting light in he visible region and light outside of the visible region to the same subject and subtracting the image by the light outside of the visible region form the image by the visible light. CONSTITUTION:The image photographed by a scope 3is taken into an image memory 13 via a CCU 10 and a switch 12 and is displayed as a real time image on a display 16 via a display memory 14. A motor 8 is then started by the command of a CPU 6 to select a UV transmission filter of a filter disk 1 and to photograph one frame. The photographed image is stored in a UV image memory 18. One frame is in succession photographed by the UV cut filter and is stored in a freeze image memory 19. The switch is simultaneously returned to the real time image display. On the other hand, the memory 18 and the memory 19 are processed by a computing element 20 and the images thereof are displayed together with the real time image on the display 16. The adverse influence of the specular reflected light is removed by constituting the device in such a manner.
