Abstract
A system for image enhancement includes a computer receiving an input image, and modifies the entire range of frequencies of the image, wherein the modifying is greater for the lower frequency aspects of the input image relative to the higher frequency aspects of the input image based upon a brightening process that is based upon a brightening selection, where the brightening selection is based upon a backlight level of a display to display the input image. The computer modifies the higher frequency aspects of the input image based upon an enhancement process that is based upon the brightening selection which is based upon the backlight level of the display. The computer combines the modifies image based upon the brightening process and the modified image based upon the enhancement process.
