1. A method of image contrast correction, comprising: analyzing an image to create an image luminance distribution histogram of said image and save said image luminance distribution histogram and said image; sampling said image luminance distribution histogram to obtain major peak values of said image luminance distribution histogram; processing the major peak values of said image luminance distribution histogram based on a first Fuzzy rule table to decide a first Fuzzy correction value, processing respectively a bright portion of said image and a dark portion of said image to decide a bright portion contrast correction strength and a dark portion contrast correction strength based on a second Fuzzy rule table and deciding a contrast correction function of said image according to said bright portion contrast correction strength, said dark portion contrast correction strength and said second Fuzzy rule table; enhancing said image with said contrast correction function to generate a corrected image; and outputting said luminance corrected image.
