Abstract: An image enhancement, for enhancing an input image, includes following steps. A distribution histogram corresponding to the input image is generated according to a probability density function of first brightness levels on pixels in the input image. A contrast enhance level is determined according to a flat factor corresponding to the distribution histogram. A weighted histogram corresponding to the input image is calculated according to the distribution histogram and the contrast enhance level. An adjusted histogram corresponding to the input image is generated by decreasing lengths of partial histogram bins in the weighted histogram. A brightness mapping curve is generated according to the adjusted histogram based on histogram equalization. The first brightness levels on the pixel in the input image are mapped into second brightness levels on pixels in an output image according to the brightness mapping curve.
