Abstract

Displaying wide-gamut images as intended on color-managed wide-gamut display systems while rendering a visually consistent image when rendered on targeted narrow-gamut display systems (regardless of whether the narrow-gamut displays are color-managed). Images represented in accordance with this disclosure are referred to as a dual-target images (DTI): one target being the image's original wide-gamut color space, the other target being a specified narrow-gamut color space. The novel representational scheme retains narrow-gamut rendering for those colors in a wide-gamut image that are within the targeted narrow-gamut color space, transitioning to wide-gamut rendering for those colors in the wide-gamut image that are outside the targeted narrow-gamut color space. This approach minimizes pixel clipping when rendering a wide-gamut image for a narrow-gamut display, while allowing the original wide-gamut pixel values to be recovered when rendering for a wide-gamut display.
