发明名称 Method for conversion of a colour space using separate chromatic and luminance look-up tables
摘要 According to the method, starting from the chromatic components xS, yS of the color vector to be converted, the components of an intermediate color vector RINT-CR, GINT-CR, &Sgr;INT-CR are-interpolated, whose chromatic components, expressed in the source color space are: xINT-CR=xS, yINT-CR=yS; starting from the luminance component SS of the color vector to be converted and from the luminance component &Sgr;INT-CR of the intermediate color vector, the luminance component &Sgr;D of the converted color vector is interpolated; the chromatic components RD, GD of the converted color vector are calculated from its luminance component &Sgr;D and from the components of the intermediate color vector RINT-CR, GINT-CR, &Sgr;INT-CR. The conversion methods of the prior art are substantially improved.
