Methods and systems for displays with chromatic correction with differing chromatic ranges
First Claim
1. A method for color correcting, comprising:
- performing color correction on source picture content, using at least one of a non-reference type display having a non-reference color gamut and a reference type display having a reference color gamut,wherein said performing step comprises;
mastering the source picture content to provide mastered color corrected picture content for display on the reference type displays having a reference color gamut; and
generating metadata for a subsequent inverse color gamut mapping that color transforms the mastered color corrected picture content for display on non-reference type displays having a non-reference color gamut, wherein the metadata describes difference between colors of the non-reference type displays and the reference type displays; and
wherein the subsequent inverse color gamut mapping is an inverse operation of a color gamut mapping applied during the color correction to obtain the mastered color corrected picture content for display on the reference type displays having the reference color gamut, and the source picture content is mastered only for the reference type displays having the reference color gamut.

Abstract
There are provided a method and system for color correcting displays with different color gamuts. The method includes performing color correction on source picture content, using at least one of a non-reference type display having a non-reference color gamut and a reference type display having a reference color gamut. The performing step includes mastering the source picture content to provide mastered color corrected picture content for display on the reference type displays having a reference color gamut. The performing step further includes generating metadata for a subsequent inverse color gamut mapping that color transforms the mastered color corrected picture content for display on non-reference type displays having a non-reference color gamut. The subsequent inverse color gamut mapping is an inverse operation of a color gamut mapping applied during the color correction to obtain the mastered color corrected picture content for display on the reference type displays having the reference color gamut. The source picture content is mastered only for the reference type displays having the reference color gamut.

6. A system for color correcting, comprising:
-
a color correction module for performing color correction on source picture content, using at least one of a non-reference type display having a non-reference color gamut and a reference type display having a reference color gamut, to provide mastered color corrected picture content for display on the reference type displays having a reference color gamut; and a color gamut mapping module for performing a color gamut mapping with respect to the mastered color corrected picture content for display on the reference type displays having the reference color gamut to generate metadata for a subsequent inverse color gamut mapping with respect to the color gamut mapping, the subsequent inverse color gamut mapping color transforming the mastered color corrected picture content for display on non-reference type displays having a non-reference color gamut, wherein the metadata describes difference between colors of the non-reference type displays and the reference type displays; and wherein the source picture content is mastered only for the reference type displays having the reference color gamut. - View Dependent Claims (7, 8)

9. A system for color correcting, comprising:
-
means for performing color correction on source picture content, using at least one of a non-reference type display having a non-reference color gamut and a reference type display having a reference color gamut, wherein said means for performing color correction comprises; means for mastering the source picture content to provide mastered color corrected picture content for display on the reference type displays having a reference color gamut; and means for generating metadata for a subsequent inverse color gamut mapping that color transforms the mastered color corrected picture content for display on non-reference type displays having a non-reference color gamut, wherein the metadata describes difference between colors of the non-reference type displays and the reference type displays; wherein the subsequent inverse color gamut mapping is an inverse operation of a color gamut mapping applied during the color correction to obtain the mastered color corrected picture content for display on the reference type displays having the reference color gamut, and the source picture content is mastered only for the reference type displays having the reference color gamut. - View Dependent Claims (10, 11, 12, 13)
