Abstract
A perceptual hue preserved (PHP) color gamut transferring (CGT) method carried out in CIE-1931 color space includes obtaining a target gamut based on a rendering device of a content. Multiple color-moving constraints (CMC) are retrieved from a dataset. Perceptually consistent hue loci (PCHL) of out-of-gamut (OOG) colors of the content are estimated according to the CMC and a protection zone boundary. Each of the OOG colors are moved along its PCHL to a final point inside the target gamut based on a CGT plan data. The CGT plan data includes target and source boundary information formed using the CMC and the protection zone boundary.

A perceptual hue preserved (PHP) color gamut transferring (CGT) method carried out in CIE-1931 color space, comprising:
- obtaining a target gamut based on a rendering device of a content;
- retrieving a plurality of color-moving constraints (CMC) from a dataset;
- estimating perceptually consistent hue loci (PCHL) of out-of-gamut (OOG) colors of the content according to the CMC and a protection zone boundary;
- moving each of the OOG colors along its PCHL to a final point inside the target gamut based on a PHP CGT plan data, wherein the PHP CGT plan data includes target and source boundary information formed using the CMC and the protection zone boundary;
- and
- displaying an output in the CIE-1931 color space that is based on the moving of each of the OOG colors.
A non-transitory processor-readable medium that includes a program that when executed by a processor performs a perceptual hue preserved (PHP) color gamut transferring (CGT) method, carried out in CIE-1931 color space, comprising:
- obtaining a target gamut based on a rendering device of a content;
- retrieving a plurality of color-moving constraints (CMC) from a dataset;
- estimating perceptually consistent hue loci (PCHL) of out-of-gamut (OOG) colors of the content according to the CMC and a protection zone boundary;
- moving each of the OOG colors along its PCHL to a final point inside the target gamut based on a PHP CGT plan data, wherein the PHP CGT plan data includes target and source boundary information formed using the CMC and the protection zone boundary;
- and
- displaying an output in the CIE-1931 color space that is based on the moving of each of the OOG colors.
An apparatus comprising:
- a memory storing instructions;
- and
- at least one processor executes the instructions including a process configured to:
- obtain a target gamut based on a rendering device of a content;
- retrieve a plurality of color-moving constraints (CMC) from a dataset;
- estimate perceptually consistent hue loci (PCHL) of out-of-gamut (OOG) colors of the content according to the CMC and a protection zone boundary;
- move each of the OOG colors along its PCHL to a final point inside the target gamut based on a perceptual hue preserved (PHP) color gamut transferring (CGT) plan data, wherein the PHP CGT plan data includes target and source boundary information formed using the CMC and the protection zone boundary;
- and
- display an output in the CIE-1931 color space that is based on the move of each of the OOG colors.
