Title: Color coordinate space structure and color quantizing and variable gray area designating method therein

Abstract: A color space structure and quantizing method is disclosed. Upon conversion from the RGB color space into HSV color space, a difference value S' (S'=max-min) is obtained by varying the maximum value of the saturation S in accordance with the value V resulting in a HS'V color space where the difference value S' forms one axis of the color coordinate, such that all of color areas are evenly distributed and the variation of color is uniformly displayed.
