Methods and systems for displays with chromatic correction having differing chromatic ranges
First Claim
1. A method for color correcting, comprising:
- performing an initial color correction on source picture content using a reference type display having a reference color gamut to obtain mastered color corrected picture content for display on reference type displays having the reference color gamut;
determining a first set of metadata defining a color gamut mapping specification for a color gamut mapping from a non-reference type display having a non-reference color gamut to the reference type display;
performing a subsequent color correction using the non-reference type display and the mastered color corrected picture content to create a second set of metadata directed to non-reference type displays having the non-reference color gamut;
generating a final set of metadata from the first set of metadata and the second set of metadata, for a subsequent color transform that color transforms the mastered color corrected picture content for display on non-reference type displays for consumer consumption,wherein the source picture content is mastered for consumer consumption only for the reference type displays having the reference color gamut.

Abstract
There are provided methods and systems for color correcting displays with different color gamuts. A method includes performing an initial color correction on source picture content using a reference type display having a reference color gamut to obtain mastered color corrected picture content for display on reference type displays having the reference color gamut. The method further includes determining a first set of metadata defining a color gamut mapping specification for a color gamut mapping from a non-reference type display having a non-reference color gamut to the reference type display. The method also includes performing a subsequent color correction using the non-reference type display and the mastered color corrected picture content to create a second set of metadata directed to non-reference type displays having the non-reference color gamut. The method additionally includes generating a final set of metadata from the first set of metadata and the second set of metadata, for a subsequent color transform that color transforms the mastered color corrected picture content for display on non-reference type displays for consumer consumption. The source picture content is mastered for consumer consumption only for the reference type displays having the reference color gamut.
