<p>The objet of the present invention consists in providing a color image processing method and apparatus for characterizing the color image signal values of a color output device using device-independent color representations. This means that the method and the apparatus of the present invention permit to determine the device-independent color values and to generate signals and hence the color image signal values for a color reproduction device, so that the color reproduction device produces colors which are identical or closest to target colors, in such a way that the human observer is not able to distinguish between the target color and the color produced by the color output device by means of the present invention. The method of the present invention consists preferably of two phases to determine the color image signal values A, B and C which will produce a desired minimum difference value ΔE, which indicates the difference between a given target color and the closest color produced by a color output device.</p> |
