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; calculating a reduction factor for each input pixel signal dependent upon differences in luminance between blue and other color components; selecting a respective saturation adjustment factor for each color component of each pixel signal; selecting a luminance gain; producing an image output signal having four color components from the image input signal using the reduction factors, saturation adjustment factors, and luminance gain to adjust the luminance and color saturation, of corresponding components 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.
