    摘要: In a method for mutual transformation between the data of a light-source color on a color CRT monitor and the data of a non-luminous object color perceived as matching with the light-source color, the transformation can be performed by using any of the following two formulas:
    R C (λ) = [I C (λ)/I G (λ)]R G (λ);
    and wherein:
    Both R C (λ), and X, Y and Z express the non-luminous object color data which are designated at a spectral reflectance factor and the CIE tristimulas values, respectively; and
    Both I C (λ), and R C , G C and B C express the light-source color data, which are designated at a spectral distribution and the RGB video drive signals, respectively.
    Unknown parameters R G (λ) and I G (λ) and k R , k G and k B , which are used in the two formulas above, are determined by visual color matching under the Color Comparison Condition in which the light-source color on the color CRT monitor and the non-luminous object color are placed side by side so that they may be simultaneously observed.
    A color comparator system for use in the method is also provided.
