Abstract
Novel methods and systems for color space conversions are disclosed, relating to the optimization of a transformation matrix to convert between wide gamut opponent color spaces. The optimization may be based on whether the color values are in or out of gamut.
Claims26
A method to perform opponent color space conversion, the method comprising:
- generating, by a computer, one or more codewords in a first opponent color space;
- performing a color space conversion, thereby converting the one or more codewords in the first opponent color space to a second opponent color space;
- and
- optimizing, by the computer, the color space conversion in order to increase a number of colors in the second opponent color space that can be perceived by a human visual system.
1 more element
A system comprising:
- a sampling module, configured to sample color values of an image;
- a gamut determination module, configured to determine whether a color value is in-gamut;
- an optimizer module, configured to optimize a transformation matrix between a first opponent color space and a second opponent color space in order to increase a number of colors in the second opponent color space that can be perceived by a human visual system;
- and
- a converter module, configured to convert color values in the first opponent color space to the second opponent color space.
