Abstract: There are many reasons cause bad contrast of image which demand many different ways to treatment, therefore, we classify the images into different categories based on the statistical information of specific images. The Adaptive Gamma Correction (AGC) is an active tool for contrast enhancement butfails to enhance the global bright images and the images with local bright regions. In this research, we suggested using (AGC) to enhance the contrast of the image byrelating the parameters of AGC with image histogram where pick point depending on the natural of image. This suggested method has been applied with many different images, the results of proposal method has been performed with high efficiency.
