US Patent 9185268, titled "Methods and systems for displays with chromatic correction with differing chromatic ranges," was issued on November 10, 2015, from an application filed on December 14, 2007. The current assignee is InterDigital Madison Patent Holdings SAS, and the inventors are Ingo Tobias Doser, Jurgen Stauder, and Bongsun Lee.

Abstract:
The patent describes methods and systems for color correcting displays that have different color gamuts. This involves performing color correction on source picture content. The process includes mastering the source content to create a color-corrected version specifically for display on non-reference type displays (those with a non-reference color gamut). Additionally, metadata is generated for a color gamut mapping. This metadata facilitates the color transformation of the mastered content for display on reference type displays (those with a reference color gamut). A key aspect is that the source picture content is mastered only for the non-reference type displays.

Independent Claims Overview:

• Claim 1 (Method): This claim outlines a method for color correction where source picture content is mastered for non-reference type displays (those with a non-reference color gamut). It further involves generating metadata for a color gamut mapping, which transforms this mastered content for display on reference type displays (those with a reference color gamut). The core limitation is that the source content is mastered only for the non-reference type displays.

• Claim 6 (Method): This independent method claim also focuses on color correction of source picture content for different display types. It includes mastering the content for non-reference type displays and also mastering the content for reference type displays. The mastering for reference type displays is achieved by applying a color gamut mapping to the content already mastered for the non-reference type displays.

• Claim 12 (System): This claim describes a system for color correcting, comprising a color correction module and a color gamut mapping module. The color correction module performs color correction on source picture content to provide mastered content for non-reference type displays. The color gamut mapping module generates metadata for a subsequent color gamut mapping to transform the mastered content for reference type displays. Similar to Claim 1, the source content is mastered only for the non-reference type displays.

• Claim 15 (System): This independent system claim outlines a system with a color correction module that masters source picture content for non-reference type displays. It also includes a color gamut mapping module that performs a color gamut mapping on the content mastered for non-reference displays to produce mastered content for reference type displays.

• Claim 20 (System - Means-Plus-Function): This claim is a "means for" claim, detailing a system with "means for performing color correction." This means for performing color correction includes "means for mastering" the source content for non-reference type displays and "means for generating metadata" for a color gamut mapping to transform that content for reference type displays. The source content is mastered only for non-reference type displays.

• Claim 25 (System - Means-Plus-Function): This is another "means for" claim for a color correcting system. The "means for performing color correction" comprises "means for mastering" the source content for non-reference type displays, and also "means for mastering" the source content for reference type displays, where this second mastering uses a color gamut mapping applied to the content mastered for the non-reference type displays.
