Abstract
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 select…
