1. An automatic photographic printing apparatus in which light from a light source which undergoes a light adjustment conducted by an automatic exposure control function of said automatic photographic printing apparatus is irradiated onto a negative color film and photographic paper is exposed by the light transmitted through the negative film so as to optically form an image therein onto the photographic paper, said automatic photographic printing apparatus being provided with a simulator for displaying the image in the negative color film as a positive image, comprising:

  • an imaging device disposed on the side of said negative color film spacedly from the light source for imaging the image in said negative color film on said side while said negative color film is being illuminated by said automatically adjusted light of the light source under said automatic exposure control function, said adjusted light being simultaneously used in both said printing apparatus for forming said image of the negative film on said photographic paper and said imaging device for simulating the image thereof;

    a display device for displaying the image obtained, as a positive image by said imaging device;

    an image information processing unit for electrically converting the output of said imaging device such that the coloring characteristics of said display device matches those of said photographic paper substantially and for causing said display device to display the results.
