Patent ID: 7253819

Claim:
A method of displaying an image on a display, the image being generated or stored with a first number of bits of color-depth resolution per pixel, the display having a second number of bits of color-depth resolution per pixel less than the first number of bits, said method comprising: accepting an image in a first color space at the first number of bits of color-depth resolution per pixel; in the case that the first color space is not in a color space having one luminance coordinate and two chrominance coordinates, converting the image to a color space having one luminance coordinate and two chrominance coordinates, with the luminance coordinate having a third number of bits of depth resolution and the chrominance coordinates each having a fourth number of bits of depth resolution; dithering the pixels of the image in the color space to produce an image in a color space with the luminance coordinate having a fifth number of bits of depth resolution and the chrominance coordinates each having a sixth number of bits of depth resolution; and converting the dithered image to RGB space for display, with each of R, G, and B having the second number of bits of color-depth resolution.
