摘要:
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.
