- The connection between the chrominance saturation control knob in a television receiver and the chrominance saturation control circuit can be achieved through wiring which transmits only DC voltage. - MANUAL CHROMINANCE SATURATION CONTROL CIRCUIT
- In color images, detail perception is obtained from the luminance component of each pixel almost exclusively, because the human vision system is not well suited to detect structures defined by varying chrominance values. - pixinsight.com

- Farveværdi for et bestemt punkt i et billede Own research - by Birgit Holst
- Example sentence(s)
- Selve billedet er opbygget af et stort antal vandrette linjer, startende øverst til venstre i billedet. Luminanssignalet indeholder information om lysindholdet af hvert enkelt lille del af en linje, og krominanssignalet fortæller om farven. Årsagen til denne opdeling i luminans og krominans skal findes i overgangen fra sort/hvide udsendelser til farveudsendelser, da signalet skulle være bagud-kompatibelt. En sort/hvid tv-modtager benytter kun luminanssignalet til at vise et billede, og de tilføjede krominansinformationer i farveudsendelserne vil ikke virke forstyrrende. - http://da.wikipedia.org/wiki/Tv by Birgit Holst

- Definition(s)
- La crominancia es la componente de la señal de vídeo que contiene las informaciones del color.
El color esta definido por dos magnitudes, la saturación, que nos da la cantidad de color y el tinte (en inglés hue) que nos dice qué color es. Dependiendo del sistema utilizado para la codificación de una imagen estas dos magnitudes toman diferentes formas.
La idea de la transmisión del color en televisión como crominancia y luminancia se debe a Georges Valensi y fue expuesta en 1938. Por aquel tiempo las pruebas realizadas transmitiendo las señales RGB evidenciaban la incompatibilidad con el sistema de televisión monocromática.

- Definition(s)
- Per CROMINANZA ("chrominance" in inglese) si intende una Combinazione di tinta e Saturazione in un colore , nonchè il Segnale che trasporta tale informazione.
Glossario informatico - by Maria Luisa Dell'Orto
- Example sentence(s)
- Per definire i colori sono solitamente necessari tre o più canali di dati : RGB , HIS , YCrCb .
In alcuni casi, come ad esempio nel Segnale Video , si è cercato di ridurre la Banda necessaria limitando a due i canali di dati: Luminanza e CROMINANZA (schema "CHROMA/LUMA").
Mentre la Luminanza corrisponde alla luminosita od alla intensità dello schema HIS , la CROMINANZA utilizza un singolo Segnale per descrivere tinta e Saturazione del colore.
Il Segnale televisivo contiene , nella stessa portante , CROMINANZA, Luminanza ed audio; il Segnale Video contiene CROMINANZA e Luminanza , mentre il super-video usa due segnali separati per CROMINANZA e Luminanza .
