Automatic photographic printing apparatus with simulator and method of adjusting simulator of automatic photographic printing apparatus
First Claim
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.

Abstract
An automatic photographic printing apparatus for printing an image in a negative color film on a photographic paper and having a simulator for displaying this image as a positive image comprises an imaging device for imaging the negative film, a display device for displaying the positive image, and an image information processing unit for matching the coloring characteristics of the photographic paper and of the display device.
A method of adjusting the simulator comprises the steps of imaging a standard negative film using the imaging device and adjusting the outputs of the imaging device such that they correspond to the density of the standard negative film.

12. A method of correcting a simulator provided in an automatic photographic printing apparatus for exposing onto photographic paper an image in a negative color film by irradiation of light adjusted by an automatic exposure control function of said automatic photographic printing apparatus, said simulator imaging the negative color film irradiated by said adjusted light and displaying on a display device the image which is to be formed on said photographic paper as a positive image, comprising the step of:
correcting the γ
characteristics of said display device and those of said photographic paper at one time.

13. A method of correcting a simulator provided in an automatic photographic printing apparatus for exposing an image in a negative color film on a photographic paper by irradiation of light adjusted by an automatic exposure control function of said automatic photographic printing apparatus, said simulator having an imaging device provided with means for controlling the amount of light for imaging the image in the negative color film by irradiation of said adjusted same light through the imaging device, said imaging device resolving the irradiated and received light into three primary colors and outputting electrical signals corresponding to said three primary colors, said simulator converting the output of said imaging device into the image and displaying the image as a positive image, comprising the steps of:
-
imaging an image on a reference negative film by using said imaging device; and adjusting gain of said electrical signals for corresponding the output of said imaging device to density of said reference negative film. - View Dependent Claims (14, 15, 16, 17, 18)
