Abstract

The color correction system will enhance an operator's ability to edit and correct the appearance of a color image. This system is particularly useful in desk-top publishing applications. A reference image with an overall desired visual impression is displayed on a screen. This reference image is known to print in an acceptable fashion and give a desired visual impression. When the image to be corrected is modified in order to approximate the visual impression of a reference picture, then the picture to be corrected should print acceptably.
