Claim:
A color space converting apparatus for converting a color value of a first color space to a color value of a second color space, said color space converting apparatus comprising: a first color space converting module for converting the color value of the first color space to the color value of the second color space so as to eliminate deviation of a converted color value derived by converting the color value of a white point of the first color space to the second color space, and the color value of a white point of the second color space, wherein the first color space converting module includes a plurality of color conversion tables, prepared for each combination of the first color space and second color space, having characteristics for matching a converted color value, derived by converting to the second color space the color value of the white point of the first color space, with the color value of the white point of the second color space; a selecting module for selecting, on the basis of a combination of the first color space and the second color space, one color conversion table from among the plurality of color conversion tables; and a second color space converting module for converting a color value of the first color space to a color value of the second color space using the selected color conversion table.
