The miniaturization and making the color image reader an ultra-high-density are advanced. However, it is rigid conditions for the noise characteristic under the low illumination environment. It previously proposed the image input process when making the color image low noised had been attempted by confining it in a specific color space getting a hint from the vision model. This method is an excellent method to decrease the color difference noise with the characteristic of the ultra-high-density preserved. However, it was powerless for these ministers of RGB noise. On the other hand, the visibility rises in many of color images' different hue in the each composition part, preserving the edge part, and smoothing the inside.We detected the difference of the color by using the parameter when confining it in a specific color space, and developed the method to detect the edge part from this information. It has been understood to have a character excellent as the detection of the edge part by the halftone dot image of the printed matter etc. assumed that this proposal method is difficult especially so far becomes possible.
