Abstract:
An embodiment of the present invention is directed to a method for determining a pixel transformation function that maximizes backlight dimming while maintaining a pre-specified distortion level. The method includes determining a minimum dynamic range of pixel values in a transformed image based on an original image and the pre-specified distortion level and determining the pixel transformation function. The pixel transformation function takes a histogram of the original image to a uniform distribution histogram having the minimum dynamic range.
