Histogram equalization (HE) is one of the common methods used for improving contrast in digital images. However, this technique will cause an effect on brightness saturation in some almost homogeneous area. In this letter, we propose a novel HE with variable enhancement degree. In this method, we can control the enhancement degree by one parameter. We also show the guide to decide the parameter. Since our method is able to control the enhancement degree, all kinds of images are enhanced efficiently.
