Color enhancement via gamut expansion

A system for color management on a computer, comprising:

• one or more destination devices configured to present video data;
• one or more graphics processing units communicatively coupled to the one or more destination devices;
• one or more memory stores communicatively coupled to the one or more graphics processing units;
• a gamut expansion logic module implemented by the one or more graphics processing units and configured to:
• detect an extent of colorfulness based at least in part on a histogram associated with an input color space, and
• determine a virtual color space based at least in part on the detected extent of colorfulness associated with the input color space;
• and
• a gamut mapping logic module implemented by the one or more graphics processing units and configured to transform input data from the input color space to the virtual color space via absolute colorimetric mapping.

An article for color management on a computer comprising a computer program product having stored therein instructions that, if executed, result in:

• detecting an extent of colorfulness based at least in part on a histogram associated with an input color space;
• determining a virtual color space based at least in part on the detected extent of colorfulness associated with the input color space;
• and
• transforming input data from the input color space to the virtual color space via absolute colorimetric mapping.

An apparatus, comprising:

• a gamut expansion means for:
• detecting an extent of colorfulness based at least in part on a histogram associated with an input color space, and
• determining a virtual color space based at least in part on the detected extent of colorfulness associated with the input color space;
• and
• a gamut mapping means for transforming input data from the input color space to the virtual color space via absolute colorimetric mapping.
