ABSTRACT:
A color reproduction system includes a color image display unit capable of displaying a color image of four or more primary colors, and a color converting unit for converting input three-primary color signals into color image signals of respective primary colors of the color image display unit. The color converting unit includes an area deciding section that decides a color conversion area to which the input three-primary color signals belong in a three-dimensional color space, and a color image signal calculating section that converts the input three primary color signals into color image signals of respective primary colors based on color conversion parameters corresponding to a color conversion area decided by the area deciding section.
