ABSTRACT:
In a method for color adjustment of a color image, a color adjustment software window is displayed and color image data on an RGB color space before color adjustment is displayed on a before-adjustment image window of a color monitor screen. An operator for color adjustment designates a color on the before-adjustment image window (or a designated color) and sets an adjustment color for the designated color (or a designated adjustment color). The designated adjustment color is set from a color pallet or by changing the R, G and B levels of a designated-color window and color adjustment parameters for the designated color are determined from the designated color and the designated adjustment color. In performing the color adjustment of a color other than the designated color (or an interpolated color), color adjustment parameters for the interpolated color are calculated on the basis of a distance between the interpolated color and the designated color on a color space to obtain the interpolated color after color adjustment which is to be displayed on an after-adjustment image window.
