Abstract
A method and apparatus for image enhancement in a display illuminated by a lighting device. Enhancement is via use of a non-linear mapping function. An illumination level for the lighting device is determined and used with the mapping function to find a compensation factor for each pixel of the image. The brightness property of each pixel is adjusted by its compensation factor.
