A color correction apparatus for minimizing a metamerism of a color scanner and a method therefor are disclosed. The apparatus includes a color measuring unit for measuring a light splitting reflection value of a color sample; a metamerism minimizing color correction unit for receiving R, G, B color values of the color sample and a light splitting reflection value inputted from the color measuring unit, obtaining a metamerism minimizing color correction parameter and converting the R, G, B color values inputted from a color scanner into a light splitting reflection value using the metamerism minimizing color correction parameter; a color value converting unit for determining a color value conversion parameter selection value in accordance with an externally inputted selection signal and converting a light splitting reflection value inputted from the metamerism minimizing color correction unit into a standard color value using the color value conversion parameter in accordance with the determined color value conversion parameter selection value; and a storing unit for providing the stored color value conversion parameter in accordance with the color value conversion parameter selection value received from the color value conversion unit and storing the metamerism minimizing color correction parameter obtained by the metamerism minimizing color correction unit. Therefore, it is possible to minimizing the metamerism of a color scanner.
