Related to chrominance: chrominance channel


The difference between one color and a reference color of the same brightness and chromaticity.

[Blend of chromo- and luminance.]


1. (General Physics) the quality of light that causes the sensation of colour. It is determined by comparison with a reference source of the same brightness and of known chromaticity
2. (Broadcasting) the information that defines the colour (hue and saturation) of a television image, but not the brightness
[C20: from chromo- + luminance]


(ˈkroʊ mə nəns)

the difference in color quality between a color and a reference color that has an equal brightness and a specified chromaticity.
[1950–55; chrom (atic) + (lum) inance]

The processed L channel is then combined with the chrominance channels ('a' and 'b') and converted back to RGB color space.
Most chrominance changes in a real scene are accompanied by a luminance change [5].

The YIQ model was designed to separate chrominance from luminance, a requirement in the early days of colour television.
It also employs chrominance and luminance sensors to calculate the varying levels of lighting depth.
264 compression algorithm, which uses the 4:2:2(3) chrominance format, enables footage of fast-moving sports like soccer to be broadcast without sacrificing quality, ensuring that viewers at home can enjoy realistic and thrilling videos of world-class soccer matches.
Moreover, the camera features color correction, color saturation, lens shading correction, software reset as well as chrominance control and maintains the ability to withstand extreme temperatures.
