Disclosed is a method of enhancing contrast of an image by using a Bezier curve. Histogram distribution is calculated based on an image that has been photographed or read out from a storage medium, the type of the image is determined according to the contrast state of the image, the movement directions of control points of a 3-D Bezier curve is determined according to the type of the image, and the movement distances of the control points of the 3-D Bezier curve are calculated based on the number of luminance values of the histogram distribution. Two control points of the 3-D Bezier curve are moved based on the movement directions and the movement distances of the control points, and the 3-D Bezier curve is created by using the two moved control points and two fixed control points. The contrast of the image is enhanced by applying the Bezier curve.
