ABSTRACT:
According to the method,starting from the chromatic components xS, ySof the color vector to be converted, the components of an intermediate color vector RINT-CR, GINT-CR, ΣINT-CRare-interpolated, whose chromatic components, expressed in the source color space are: xINT-CR=xS, yINT-CR=yS;starting from the luminance component SSof the color vector to be converted and from the luminance component ΣINT-CRof the intermediate color vector, the luminance component ΣDof the converted color vector is interpolated;the chromatic components RD, GDof the converted color vector are calculated from its luminance component ΣDand from the components of the intermediate color vector RINT-CR, GINT-CR, ΣINT-CR. The conversion methods of the prior art are substantially improved.
