method for color matching of farbbildverarbeitungsvorrichtungen with interpolation of a relatively small number of farbdatengruppen

摘要

Color matching method wherein relatively small number of input color data sets (Xn, Rn) are applied to first image processor (10, 14), to obtain the corresponding output color data sets (Rn, Xn) which are interpolated to obtain relatively large number of output color data sets, which are used to obtain relatively large number of the corresponding input color data sets by inverse estimation, for obtaining first high-resolution input-output relationship Rn = fimag(Xn) or Xn = fdisp(Rn) of the first image processor, and wherein second high-resolution input-output relationship (Xn = fdisp(Rn) or Xn = fcopy(Rn) of second image processor (24, 20) is similarly obtained, so that a color data correlationship Rn(SG2) = f(Rn(SG1)) or Rn(SG3) = f(Rn(SG2)) for converting the relatively large number of input color data sets of the first image processor into the relatively large number of input color data sets of the second image processor is obtained according to the first and second high-resolution input-output relationships.
