[Blend of chromo– and luminance.]

Blend of chroma and luminance

Examples

  • We quickly forget that chrominance is missing as our perceptual system depend primarily on luminance.

    Audio quality does matter

  • Normally, the wardrobe folk make sure people aren't wearing stripes or patterns, where an interaction between fabric pattern and video scanning pixel pattern causes 'cross-colour interference' (i.e. the luminance signal breaks through into the chrominance).

  • The Sony A500 uses a combination of on-sensor noise reduction at each photocell location, plus a two-step noise reduction procedure which operates both before and after analog-to-digital conversion, processing chrominance and luminance noise separately.

  • With the Lumix LX5's processor, though, Panasonic's engineers finally had enough computing horsepower at their disposal to look at luminance (brightness) noise and chrominance (color) noise both separately and together.

  • The Windows version wouldn't apply chrominance or luminance noise reduction to images.

  • Componet Video: aka: YPbPr, YCbCr, YUV. contains luminance (Y) signal and separate chrominance (PR and PB) elements.
