ABSTRACT:
The color scanning signals generated by scanning the original are first converted into three primary color signals having actual color values in a predetermined color coordinate system corresponding substantially identically to theoretical color values of the original. It is only after this conversion that the primary signals or signals derived from these signals are converted to another color rendition system, or the gradation is altered, or the color rendition of individual colors in the overall image or in discrete areas is altered, or any other non-linear processing takes place.
