Definition of chrominance in English:

chrominance

noun ˈkrəʊmɪnənsˈkrōmənəns

mass noun

The colorimetric difference between a given colour in a television picture and a standard colour of equal luminance.
Example sentencesExamples
- This transform space allows luminance and chrominance to be processed separately.
- A sequence of passes separates the luminance and chrominance information from the composite video signal and demodulates the color carrier to separate out color information.
- Color images typically have three components, corresponding to the red, green, and blue intensities, or the luminance and two chrominance components.
- The value of a blending coefficient for a pixel in the graphic is based on the luminance and chrominance characteristics of a neighborhood of pixels in the video.
- Typically, each pixel is encoded for luminance, but chrominance is averaged for groups of four pixels, saving about half the bandwidth required to transmit the full-resolution image.

Origin

1950s: from Greek khrōma 'colour', on the pattern of luminance.
