摘要： 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.

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.

摘要： A method and system for characterization of a display for facilitating the calibration of the display values of input content in response to dynamic behavior caused by changes in average power (picture) level of the input content include determining a level of average power (APL) in the input content and applying a transform to the input content to determine display values for the input content based on the determined APL of the input content. The transform, in one embodiment of the invention is based on a display characterization which includes a measurement of at least one APL on the display. In one embodiment of the present invention, the transform is a four dimensional look-up table that maps input content color values to respective human visual system values for different average power levels.

摘要： A system and method for compensating for average brightness dependency (ABD) differences between displays with and without average brightness dependency (ABD) includes color correcting source picture content on a reference display to output color corrected picture content. In addition, an ABD simulation process uses the color corrected picture content to simulate the display of content on the reference display. Subsequently, a compensation process receives the color corrected picture content and information from the simulation process and applies an ABD compensation characteristic to the color corrected picture content for correctly displaying the source picture content on a display with different ABD characteristics than the reference display.
