  • Patent number: 4577219
    Abstract: In a method for copying retouch in color picture reproduction, color values are initially acquired by image-point-by-image-point trichromatic color picture scanning and digitization. The color values are deposited in a storage medium and are addressable by image point coordinates. With the coordinate pen of a coordinate acquisition means, the retoucher first marks a read point within a first image region from which a pattern is to be taken and a write point within a second image region into which the pattern is to be copied with image point precision. A distance between the read and write points is determined from the acquired image point coordinates and is fixed. The retoucher then acquires all image point coordinates within the first image region with the assistance of a coordinate pen.
