Image enhancement plays an important role to the image or video display systems. It is used to process an input image and the output image is more pleasing than the input one. Many contrast enhancement techniques proposed so far. Among them histogram equalization (HE) is widely used for contrast enhancement technique. In this paper, we propose a new technique of histogram equalization method which preserves the brightness of the image. We tested the proposed method on a variety of images. The proposed method is also compared with some other related methods. We also use some parameters for comparison and the proposed method gives better performance than the related methods.
