Abstract:
    This invention relates to an image signal process technology, especially to a method for enhancing the brightness and contrast of images, which divides the gray scale of an original image into 16 levels to carry out linear approximate histogram accumulation in the process of equalizing image gray scale histograms, sets a control parameter to process the original image adaptively and dynamically, which is advantaged that the brightness, the image hierarchy and the contrast of the original image is increased.
