Abstract
A method for contrast enhancement of pixel data of a decompressed color image includes the steps of computing I component values in an HSI color space for the pixel data of the color image, computing an image I component value which is an average of the computed I component values, and enhancing each of the pixel data of the color image according to the image I component value. An apparatus for contrast enhancement of pixel data of a decompressed color image is also disclosed.
