1. Apparatus for analyzing and printing color and density corrected photographic prints from color film, comprising in combination:
- video color film analyzer means for reviewing a positive image on a cathode ray tube taken from a color film, said analyzer having means for adjusting the color and density values of the image on the tube; and
photographic printing means having means for receiving said adjusted color and density values from said video color film analyzer means and simultaneously converting said color and density values into corresponding timed increments for directly controlling the exposure of the color film for immediate use in printing a color and density corrected photograph.

Abstract
An improved color photographic printing apparatus which has a video analyzer for viewing a film negative before printing, and has circuitry for controlling the color and density of the image and for controlling the printing times of a photographic printer through a mirror computer to produce a photographic print which is the same as the image seen on the video analyzer.

9. A method of analyzing a film negative and printing a color and density corrected photographic reproduction of the image on the film negative, comprising the steps of
analyzing a film negative with a video film analyzer to project a positive color image of the negative on a cathode ray tube; -
adjusting the color and density of the projected image to correct deficiencies in color and density; converting the adjusted color and density values to digital values; introducing said digital values directly into a micro processor; converting said digital values into timed increments; and applying said time increments to actuate shutter means, printing light and color filter means in a photographic printing means to produce a color and density corrected photograph. - View Dependent Claims (10)
