PROBLEM TO BE SOLVED: To provide such a photographic apparatus for an endoscope with which the color tones adequate for diagnosis may be obtained even if the brightness of inputted endoscope images change. SOLUTION: The component images of R, G and B of the video signals of the endoscope images outputted from an electronic endoscope apparatus 2 are stored by one screen component into an image memory 4 through an A/D converter 3 at the time of photographing. The average brightness thereof is judged as to whether the images are dark images below the threshold or not in an average luminance detecting circuit 5. In the case of the bright images, the images are subjected toγcorrection with a ROM of common characteristics inγcorrection circuits 6R, 6G and 6B for R, G and B. In the case of the dark images, the images are subjected toγcorrection with a ROM of the characteristic to make the output levels of the G and B images higher than the output level of the R image and the luminance levels are successively made to emit light and are displayed with the respective color component images of R, G and B by a CRT 12. These images are multiexposed to a film 19 by a camera 16 through filters 14R, 14G and 14B of a rotary filter 13, by which the photographed images of the adequate color tones suitable for diagnosis may be obtained even if the brightness of the inputted endoscope images changes particularly small.
