  • Method for screen-adaptive copy retouching
    Patent number: 7133160
    Abstract: A method for copy retouching digital image data which contains a periodic pattern, includes calculating a distance vector D1 from the initially defined starting positions of a read mark and a write mark. The image data are then copied from the image points located under the read mark to the image points located under the write mark. In order to avoid a possible offset of the copied pattern area with respect to the surrounding pattern, a corrected distance vector D2 is calculated in such a way that the read mark and the write mark have the same phase position in relation to the periodic pattern. The method is particularly suitable for copy retouching of screened color separation data.

  • Method for automatically selecting color calibrations
    Patent number: 6724422
    Abstract: In a method for automatically selecting color calibrations for digital color image recording, especially for digital photography or digital video recording in any lighting conditions, at least one color calibration is produced and stored by recording a calibrated color table. The color calibration which best resembles the color cast of a color image is selected on the basis of the correlation between the color cast parameters of the color image which is being recorded and the respective color calibration. In the event that no matching color calibration is found by comparing the color cast parameters, a standard color calibration is selected.
