Abstract

A photographic image computer analyzer electronically scans a color image and generates data representing the intensity of each of the red (R), green (G) and blue (B) color values of any picture element (pixel). The data is stored, corrected or modified as desired, and used to drive a color CRT to project a superimposed enhanced image for viewing or for projection onto a printing medium. Using a standard photographic enlarger as an example, an RGB color CRT is placed in the lamp housing to emit red, blue, green, or white light to the film image to be enlarged. An image analyzer is placed in the focal plane of the projected image, such as on the enlarging easel underneath the light beam.
