In the photographic color printing process, a method which operates to suppress color subject failure and to correct film variability simultaneously is required. To correct film variability, it is necessary to know the tone reproduction characteristics of the color negative film in advance of printing. On the other hand, it is known that density cumulative distribution function of photographic color image is concerned with the photographic characteristic curve of the film. In this paper, a new color correction method using density cumulative distribution function is described and the experimental results are discussed. Further, a pararell image processing system suitable for this color correction method and exposure control is introduced.
