PURPOSE:To record vividly a photographic image recorded at plural kinds of objects to be photographed to recording media by arranging selectively, in the optical system light path of the image pick-up means, the optical filter to correct so as to make the spectral characteristic of the image pick-up part coincident with the spectral characteristic of respective photographing objects. CONSTITUTION:By arranging selectively, at the edge part of the light source side of a diffusion box 24, a color resolving prism 52 to satisfy the spectral characteristic of both negative film and reversal film and a trimming filter 60 to insulate an optical component of the unnecessary wavelength area respectively according to the fact whether the photographing object is a negative film or a reversal film, an optical system spectral characteristic including an image pick-up part 50 is made coincident with the spectral characteristic of respective photographing objects. For example, in case of a negative film, a trimming film 60 which is lowest in the vicinity of the transmission ratio of 630nm and flat at the wavelength area <=570nm or >=700nm, or in case of the reversal film, a trimming filter 60 which is zero at the wavelength area of the transmission ratio >=720nm and flat at the wavelength area <=650nm are selected.
