This paper proposes an improved method that uses a *K*-means method to effectively reduce the ringing artifacts in a color moving picture. To apply this improved *K*-method, we set the number of groups for the process to two (*K*=2) in the three dimensional *R*, *G*, *B* color space. We then improved the *R*, *G*, *B* color value of all of the pixels by moving the current *R*, *G*, *B* color value of each pixel to calculated center values, which reduced the ringing artifacts. The results were verified by calculating the overshoot and the slope of the light luminance around the edges of test images that had been processed by the new algorithm. We then compared the calculated results with the overshoot and slope of the light luminance of the unprocessed image.
