<p>PURPOSE: A color correction method of an image using a touch screen is provided to enable color correction by a series of successive movements. CONSTITUTION: If a touch to one of three point coordinates(1,2,3) is sensed(S30), a touch screen checks whether fingers move within a set time(S40). If detecting movements of fingers within a set time, the touch screen changes the point coordinates to a changed position by the fingers(S50) and values of the changed coordinates is cached(S51). The touch screen calculates color correction values using current position coordinates and the cashed previous position coordinates, or using current set central position coordinates and previous set central position coordinates, through a circular application(S60), and corrects values of color attributes of an image based on the color correction values(S70). The touch screen cashes the corrected values of color attributes of the image(S80).
