Colorimetry - Part 5: CIE 1976 L*u*v* Colour space and u', v' uniform chromaticity scale diagram (ISO 11664-5:2009)
ISO 11664-5:2009 specifies the method of calculating the coordinates of the CIE 1976 L*u*v* colour space including correlates of lightness, chroma, saturation and hue. It includes two methods for calculating Euclidean distances in this space to represent the relative perceived magnitude of colour differences. It also specifies the method of calculating the coordinates of the u',v' uniform chromaticity scale diagram.
ISO 11664-5:2009 is applicable to tristimulus values calculated using the colour-matching functions of the CIE 1931 standard colorimetric system or the CIE 1964 standard colorimetric system. ISO 11664-5:2009 may be used for the specification of colour stimuli perceived as belonging to a reflecting or transmitting object, where a three-dimensional space more uniform than tristimulus space is required. This includes self-luminous displays, like cathode ray tubes, if they are being used to simulate reflecting or transmitting objects and if the stimuli are appropriately normalized. ISO 11664-5:2009, as a whole, does not apply to colour stimuli perceived as belonging to an area that appears to be emitting light as a primary light source, or that appears to be specularly reflecting such light.
Farbmetrik - Teil 5: CIE 1976 L*u*v* Farbenraum und gleichabständige u’, v’-Farbtafel (ISO 11664-5:2009)
Diese Internationale Norm legt das Verfahren zum Berechnen der Koordinaten des L*u*v*-Farbenraums CIE 1976 fest, Korrelate von Helligkeit, Buntheit, Sättigung und Buntton eingeschlossen. Sie legt zwei Verfahren zum Berechnen euklidischer Abstände in diesem Farbenraum fest, die der relativen empfindungs-gemäßen Größe von Farbabständen entsprechen. Außerdem legt sie das Verfahren zum Berechnen der Koordinaten der gleichabständigen u, v-Farbtafel fest.
Diese Norm ist anwendbar auf Farbwerte, die nach den Spektralwertfunktionen des Normvalenzsystems CIE 1931 oder des Normvalenzsystems CIE 1964 berechnet sind. Diese Norm kann angewendet werden für die Festlegung von Farbreizen, die als zu einem reflektierenden oder transmittierenden Objekt zugehörig empfunden wurden, wenn ein dreidimensionaler Farbenraum, der gleichabständiger ist als der Farbenraum der Farbwerte, benötigt wird. Dies schließt selbstleuchtende Displays, wie Kathodenstrahlröhren ein, wenn sie dazu verwendet werden, reflektierende oder transmittierende Objekte zu simulieren, und wenn die Farbreize in geeigneter Weise normiert sind. Diese Norm als Ganzes ist nicht anwendbar auf Farbreize, die als zu einer Fläche zugehörig empfunden wurden, die Licht als eine primäre Lichtquelle zu emittieren oder solches Licht gerichtet zu reflektieren scheint. Nur die in 4.1 definierte u, v-Farbtafel und die im 4.3 definierten Korrelate von Buntton und Sättigung sind auf solche Farbreize anwendbar.
Colorimétrie - Partie 5: Espace chromatique L*u*v* et diagramme de chromaticité uniforme u', v' CIE 1976 (ISO 11664-5:2009)
L'ISO 11664-5:2009 spécifie la méthode de calcul des coordonnées de l'espace chromatique L*u*v* CIE 1976 ainsi que des correspondants de clarté, de saturation, de chroma et de teinte. Elle donne deux méthodes de calcul de la distance euclidienne dans cet espace, représentant la valeur perçue des différences de couleur. Elle spécifie également la méthode de calcul des coordonnées u', v' du diagramme de chromaticité uniforme.
L'ISO 11664-5:2009 est applicable aux composantes trichromatiques calculées en utilisant les fonctions colorimétriques du système colorimétrique normalisé CIE 1931 ou du système colorimétrique normalisé CIE 1964. L'ISO 11664-5:2009 peut être utilisée pour la spécification de stimulus de couleur se rapportant à des objets qui réfléchissent ou qui transmettent la lumière, pour lesquels un espace chromatique tridimensionnel plus uniforme que le système trichromatique est nécessaire. Ceci comprend les afficheurs auto-lumineux, tels que les tubes cathodiques, quand ils sont utilisés pour simuler des objets qui réfléchissent ou transmettent la lumière, si les stimulus sont convenablement normalisés. L'ISO 11664-5:2009, dans son ensemble, ne s'applique pas à des stimulus de couleur se rapportant à des surfaces qui paraissent émettre de la lumière comme le font les sources primaires de lumière ou qui apparaissent réfléchir spéculairement de telles lumières.
Kolorimetrija - 5. del: CIE 1976 L*u*v* barvni prostor in u', v' diagram enakomerne barvnosti (ISO 11664-5:2009)
ISO 11664-5:2009 določa metodo za izračun koordinat barvnega prostora CIE 1976 L*u*v*, vključno s korelati svetlosti, kromatičnosti, nasičenosti in barve. Vključuje dve metodi za izračun evklidskih razdalj v tem prostoru, ki pomenita relativen zaznan obseg razlik v barvah. Določa tudi metodo za izračun koordinat diagrama enakomerne barvitosti u',v'.
ISO 11664-5:2009 velja za vrednosti tristimulusa, ki se izračunajo z uporabo funkcije barvnega usklajevanja kolorimetričnega sistema po standardu CIE 1931 ali kolorimetričnega sistema po standardu CIE 1964. ISO 11664-5:2009 se lahko uporablja za specifikacijo barvnih dražljajev, ki se zaznajo kot del refleksijskega ali transmisijskega objekta, pri katerem je potreben trodimenzionalni prostor, enotnejši od tristimulusnega prostora. To vključuje samosvetleče zaslone, kot so zasloni s katodnimi cevmi, če se uporabljajo kot simulacija refleksijskih ali transmisijskih objektov in če se dražljaji ustrezno normalizirajo. ISO 11664-5:2009 kot celota ne velja za barvne dražljaje, ki se zaznajo kot del območja, ki na prvi pogled oddaja svetlobo kot primarni vir svetlobe ali ki na prvi pogled tako svetlobo zrcalno odbija.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
ISO 11664-5 was prepared as Standard CIE S 014-5/E by the International Commission on Illumination, which
has been recognized by the ISO Council as an international standardizing body. It was adopted by ISO under
a special procedure which requires approval by at least 75 % of the member bodies casting a vote, and is
published as a joint ISO/CIE edition.
The International Commission on Illumination (abbreviated as CIE from its French title) is an organization
devoted to international cooperation and exchange of information among its member countries on all matters
relating to the science and art of lighting.
ISO 11664-5 was prepared by CIE Technical Committee 1-57 of division 1, Vision and colour.
ISO 11664 consists of the following parts, under general title Colorimetry:
— Part 1: CIE standard colorimetric observers
— Part 2: CIE standard illuminants
— Part 4: CIE 1976 L*a*b* Colour space

FOREWORD
Standards produced by the Commission Internationale de l’Eclairage (CIE) are a concise
documentation of data defining aspects of light and lighting, for which international harmony
requires such unique definition. CIE Standards are therefore a primary source of
internationally accepted and agreed data, which can be taken, essentially unaltered, into
universal standard systems.
This CIE Standard has been prepared by the Technical Committee TC 1-57* of
Division 1 "Vision and Colour" and was approved by the National Committees of the CIE.
The following ISO and IEC committees and working groups co-operated in the
preparation of this standard:
IEC TC100/TA2 (Audio, Video and Multimedia Systems)
ISO TC6 (Paper, Board and Pulps)
ISO TC35/SC9/WG22 (Paint and Varnishes)
ISO TC38/SC1/WG7 (Textiles)

COLORIMETRY - PART 5: CIE 1976 L*u*v* COLOUR SPACE AND u′, v′
UNIFORM CHROMATICITY SCALE DIAGRAM
INTRODUCTION
The three-dimensional colour space produced by plotting CIE tristimulus values (X,Y,Z) in
rectangular coordinates is not visually uniform, nor is the (x,y,Y) space nor the two-
dimensional CIE (x,y) chromaticity diagram. Equal distances in these spaces and diagrams
do not represent equally perceptible differences between colour stimuli. For this reason, in
1976, the CIE introduced and recommended two new spaces (known as CIELAB and
CIELUV) whose coordinates are non-linear functions of X, Y and Z. The recommendation was
put forward in an attempt to unify the then very diverse practice in uniform colour spaces and
associated colour difference formulae (Robertson, 1990; CIE, 2004). Both these more-nearly
uniform colour spaces have become well accepted and widely used. Numerical values
representing approximately the relative magnitude of colour differences can be described by
simple Euclidean distances in the spaces or by more sophisticated formulae that improve the
correlation with the relative perceived size of differences. The purpose of this CIE Standard is
to define procedures for calculating the coordinates of the CIE 1976 L*u*v* (CIELUV) colour
space and the Euclidean colour difference values based on these coordinates. The standard
also defines a related chromaticity diagram that is a projection of the CIE x,y diagram
maintaining straight lines of dominant and complementary wavelengths. The standard does
not cover the alternative uniform colour space, CIELAB (CIE, 2007), nor does it cover more
sophisticated colour difference formulae based on CIELAB, such as the CMC formula (Clarke
et al., 1984), the CIE94 formula (CIE, 1995), the DIN99 formula (DIN, 2001), and the
CIEDE2000 formula (CIE, 2001).
1. SCOPE
This CIE Standard specifies the method of calculating the coordinates of the CIE 1976 L*u*v*
colour space including correlates of lightness, chroma, saturation and hue. It includes two
methods for calculating Euclidean distances in this space to represent the relative perceived
magnitude of colour differences. It also specifies the method of calculating the coord
