A method for producing an extended color gamut luminance-chrominance
digital image from a captured digital image includes determining an
estimate of the colors of the captured digital image of an original scene
and further processing to produce an extended range output RGB image
value including values outside the range that can be displayed on the
output image display device, and producing an extended color gamut
luminance-chrominance digital image by transforming the extended range
output RGB image values to a luminance-chrominance representation.
