![](https://cfcdn.proz.com/images/wikiwords/small_grey_arr.gif) - 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

- 色度(chrominance或chroma)
色度是水质的外观指标,水的的颜色分为表色和真色。真色是指去除悬浮物后水的颜色,没有去除的水具有的颜色称表色。对于清洁的或浊度很低的水,真色和表色相近,对于着色深的工业废水和污水,真色和表色差别较大。而水的色度一般指真色,水的颜色常用以下方法测定:1.铂钴标准比色法(常用于天然水和饮用水,单位 度) 2.稀释倍数法(常用于工业废水,单位 倍) - 色度

- Χρωματικές συνιστώσες (συνιστώσες χρωματικότητας): συνιστώσες για την φασματική περιγραφή χρώματος ΤΕΙ ΚΡΗΤΗΣ - by laontas
- Example sentence(s)
- Κατά το στάδιο του χαρακτηρισμού η πληροφορία
χρώματος, κίνησης και βάθους του κάθε τμήματος διατηρείται έτσι ώστε να παρέχεται ευέλικτη αναπαράσταση του οπτικού περιεχομένου, και η διαχείριση ή αναζήτηση κάθε είδους πληροφορίας να μην επηρεάζεται από τις υπόλοιπες.
Συγκεκριμένα, το πλήθος τμημάτων χρώματος καθώς και η θέση, το μέγεθος και οι μέσες χρωματικές συνιστώσες τους χρησιμοποιούνται για την κατασκευή ενός διανύσματος περιγραφής χρώματος. - ΕΘΝΙΚΟ ΜΕΤΣΟΒΕΙΟ ΠΟΛΥ

- 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

- 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)
- A crominância (C), é um dos dois elementos que conformam um sinal de vídeo, junto com a luminância (Y). A crominância refere-se ao valor das cores, enquanto a luminância se refere às luzes -branco e preto-. Os diferentes sistemas de difusão de vídeo -NTSC, PAL, SECAM, etc.- permitem misturar ou enviar por separado ambos os elementos.
Em retransmissões televisivas, os valores C/Y são o primeiro a comprovar, posto que uma má qualidade ou sincronização resultaria num pêssimo sinal. Wikipédia - by Joao Vieira
- Example sentence(s)
- CROMINÂNCIA
Característica da imagem que é definida por dois valores: coloração e saturação. A coloração é a parte de luz reflectida por um objecto. Este absorve luz e reflecte apenas uma parte do espectro visível. A saturação define a proporção de branco que uma côr contém. Quanto maior for a percentagem de branco, tanto menor será o seu brilho. As placas gráficas de qualidade tratam a crominância e a luminância de forma muito aperfeiçoada. - Multimedia de A a Z, de Carlos Correia
by Joao Vieira - 4.10 - Largura de faixa das faixas laterais de crominância (modulação em quadratura da subportadora) (kHz) - Anacom

- 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 .

- Chrominantie (chroma verkort) draagt in een component videosignaal de kleurinformatie, waar de luminantie de lichtintensiteit draagt. De combinatie van chrominantie en luminancie geven een volledig kleurenspectrum. Chrominantie wordt in verschillende videosignalen gebruikt zoals in YUV, YCbCr, YIQ,... Wiki - by vic voskuil
- Example sentence(s)
- Chrominantie: Kleurcomponent van een videosignaal. Zwart en wit hebben geen chrominantie. Een videosignaal bestaat uit chrominantie, sync en luminantie. - Computerwoorden
