ABSTRACT:
A method and apparatus adjusts the contrast of an input image formed of pixels. Each pixel in the input image has an input brightness level. At least some of the pixels in the output or enhanced image have an output brightness level that is different from their input brightness level. Brightness level data of the input image is filtered to obtain a high frequency component of the input image in a single operational stage. The high frequency component is amplified. The original image and the amplified high frequency component are summed to produce brightness level data of the output image.
