1. A system for determining at least one color of a foreground, the system comprising: at least one processor configured to implement: a motion detector configured to detect a motion region from an image; and a color determiner configured to i) determine the color of the foreground included in the motion region based on a difference between at least one color of the motion region and at least one color of a surrounding region of the motion region ii) generate a color histogram of the surrounding region and a color histogram of the motion region, iii) obtain a color histogram of the foreground based on a difference between the color histogram of the motion region and the color histogram of the surrounding region, and iv) determine the color of the foreground from the color histogram of the foreground, for displaying the determined color with the foreground at a display device, wherein the color of the foreground is a representative color which has the highest frequency in two or more colors of the foreground shown in the color histogram of the foreground.
