ABSTRACT:
A pixel of a digital image is processed by applying a tone mapping function to a first color channel of the pixel, whereby a value of the first color channel is changed by a scale factor; and applying the scale factor to all other color channels of the pixel. The first color channel most closely matches relative luminance response of the human visual system.
