FOUR-CHANNEL DISPLAY POWER REDUCTION WITH DESATURATION
First Claim
1. A method of presenting an image on a display device having color channel dependent light emission comprising:
- (a) receiving an image input signal including a plurality of input pixel signals, each input pixel signal having three color components;
(b) selecting a reduction color component;
(c) calculating a reduction factor for each input pixel signal dependent upon a distance metric between the input pixel signal and the selected reduction color component;
(d) selecting a respective saturation adjustment factor for each color component of each pixel signal;
(e) producing an image output signal having four color components from the image input signal using the reduction factors and saturation adjustment factors to adjust the luminance and color saturation, respectively, of the image input signal;
(f) providing a four-channel display device having color channel dependent light emission; and
(g) applying the image output signal to the display device to cause it to present an image corresponding to the image output signal.

Abstract
A method of presenting an image on a display device having color channel dependent light emission comprising receiving an image input signal including a plurality of three-component input pixel signals; selecting a reduction color component; calculating a reduction factor for each input pixel signal dependent upon a distance metric between the input pixel signal and the selected reduction color component; selecting a respective saturation adjustment factor for each color component of each pixel signal; producing an image output signal having four color components from the image input signal using the reduction factors and saturation adjustment factors to adjust the luminance and color saturation, respectively, of the image input signal; providing a four-channel display device having color channel dependent light emission; and applying the image output signal to the display device to cause it to present an image corresponding to the image output signal.
