ABSTRACT:
A method for displaying a color image by providing a color image display apparatus having at least three narrow-band emissive light sources that define a display color gamut. Image data values are accepted that are defined within an original color gamut that is smaller in area than the display color gamut. The input image data values are transformed into display color gamut data values having an expanded image chromaticity range. At least a portion of the expanded chromaticity range lies outside the original color gamut. At least a portion of the display color gamut lies outside the expanded image chromaticity range. The display color gamut data values are provided to the color image display apparatus to form an image.
