A color original is entered by an input means for prescan, a density distribution with respect to a hue is obtained for each electric signal of color image information, and a characteristic point of the color original image is obtained from the result of the density distribution. The two-color separation means separates a full-colored original to two colors free from the same color representation according to the information of the characteristic point obtained.
