Abstract
This paper deals with a new distance measurement method of color images by using an RGB color histogram. We measure the distance based on the principle of depth-from-focus. It needs to detect focal position among many images with different focusing position. Our method is based on that the more focal area has the less color frequency. By this method, we detect the focal area without using spatial frequency as in conventional methods. The validity of our method is verified by some experimental results
