摘要：
Apparatus and method for electronically retouching color images reproductions in which the color signals are generated by means of scanning image point by image point and by trichromatic master scanning and then the signals are digitized and the digital color values of the individual color components are stored in a storage medium and the stored color values are then changed by identifying the coordinates of the image points to be changed in the color image and simultaneously determining the coordinate identification and the locally dependent correction values for the digital color values of the color components and then changing the digital color values by applying correction values at the correction locations so as to obtain the retouched color values.
