description The present invention provides an image contrast enhancement method, which respectively calculates the absolute values of the differences of the gray scales between the pixels of two adjacent row of the same column and between the pixels of two adjacent column of the same row, and respectively calculates the first gray scale value weight and the second gray scale value weight according to the absolute values. Then, the cumulative calculation and the normalization process are performed according to the first, the second gray scale value weights. Ultimately, the enhancement gray scale table is obtained for redistributing the gray scale values of the respective pixels, which can raise the contrast of the image, reduce the distortion of the image and optimize the display result.
