Colorimetry - Part 3: CIE tristimulus values (ISO/CIE 11664-3:2019)
This document specifies methods of calculating the tristimulus values of colour stimuli for which the spectral distributions are provided. These colour stimuli can be produced by self-luminous light sources or by reflecting or transmitting objects.
This document requires that the colour stimulus function be tabulated at measurement intervals of 5 nm or less in a wavelength range of at least 380 nm to 780 nm. Extrapolation methods are suggested for cases where the measured wavelength range is less than 380 nm to 780 nm.
The standard method is defined as summation at 1 nm intervals over the wavelength range from 360 nm to 830 nm. Alternative abridged methods are defined for larger intervals (up to 5 nm) and shorter ranges (down to 380 nm to 780 nm). The alternative methods are to be used only when appropriate and when the user has reviewed the impact on the final results.
This document can be used in conjunction with the CIE 1931 standard colorimetric observer or the CIE 1964 standard colorimetric observer.
Farbmetrik - Teil 3: CIE-Farbwerte (ISO/CIE 11664-3:2019)
Dieses Dokument legt Verfahren zur Berechnung von Farbwerten aus Farbreizen, für die die Spektralverteilungen gegeben sind, fest. Diese Farbreize können von selbstleuchtenden Lichtquellen oder durch reflektierende oder transmittierende Objekte erzeugt werden.
Dieses Dokument erfordert, dass die Farbreizfunktion in Messintervallen von 5 nm oder weniger in einem Wellenlängenbereich von mindestens 380 nm bis 780 nm tabelliert wird. Für Fälle, bei denen der gemessene Wellenlängenbereich kleiner als 380 nm bis 780 nm ist, werden Extrapolationsverfahren vorgeschlagen.
Das Normverfahren wird als Summierung bei Intervallen von 1 nm über den Wellenlängenbereich von 360 nm bis 830 nm definiert. Für größere Intervalle (bis zu 5 nm) und kleinere Bereiche (bis auf 380 nm bis 780 nm) werden Kurzverfahren definiert. Die alternativen Verfahren sind nur dann anzuwenden, wenn sie geeignet sind und der Anwender die Auswirkung auf die Endergebnisse überprüft hat.
Dieses Dokument kann zusammen mit dem farbmetrischen Normalbeobachter CIE 1931 oder dem farbmetrischen Normalbeobachter CIE 1964 angewendet werden.
Colorimétrie - Partie 3: Composantes trichromatiques CIE (ISO/CIE 11664-3:2019)
Le présent document spécifie les méthodes de calcul des composantes trichromatiques des stimulus de couleur dont les répartitions spectrales sont disponibles. Ces stimulus de couleur peuvent être produits par des sources primaires de lumière ou par des objets qui réfléchissent ou qui transmettent la lumière.
Le présent document impose que la fonction de répartition spectrale du stimulus étudié soit donnée à des intervalles de mesure de 5 nm, ou à des intervalles plus faibles, dans un domaine de longueurs d'onde s'étendant au moins de 380 nm à 780 nm. Des méthodes d'extrapolation sont suggérées dans les cas où le domaine de longueurs d'onde mesuré est moindre que de 380 nm à 780 nm.
La méthode normalisée est définie comme une sommation à des intervalles de 1 nm sur un domaine de longueurs d'onde compris entre 360 nm et 830 nm. Des méthodes alternatives simplifiées sont définies pour des intervalles plus grands (jusqu'à 5 nm) et des domaines plus réduits (limités de 380 nm à 780 nm). Ces méthodes alternatives ne sont à utiliser que si leur emploi le nécessite et si l'utilisateur a évalué leur impact sur les résultats définitifs.
Le présent document peut être utilisé en liaison soit avec l'observateur CIE 1931 de référence pour la colorimétrie, soit avec l'observateur CIE 1964 de référence pour la colorimétrie.
Kolorimetrija - 3. del: Barvne vrednosti CIE (ISO/CIE 11664-3:2019)
Ta dokument določa metode za izračun barvnih vrednosti barvnih dražljajev, za katere je podana spektralna porazdelitev. Te barvne dražljaje lahko povzročijo samosvetilni svetlobni viri ali odbojni predmeti ali oddajniki.
Ta dokument zahteva, da se funkcija barvnih dražljajev tabelira v intervalih merjenja največ 5 nm v razponu valovnih dolžin od najmanj 380 nm do 780 nm. Metode ekstrapoliranja so priporočene v primerih, kjer so merjeni razponi valovnih dolžin manjši od 380 nm do 780 nm.
Standardna metoda je določena kot vsota intervalov 1 nm v razponu valovnih dolžin od 360 nm do 830 nm. Alternativne skrajšane metode so določene za večje intervale (več kot 5 nm) in za krajše razpone valovnih dolžin (krajše od 380 nm do 780 nm). Alternativne metode se uporabljajo samo, kadar je to ustrezno in kadar je uporabnik pregledal vpliv na končne rezultate.
Ta dokument se lahko uporablja v povezavi s standardiziranim barvnometričnim opazovalcem CIE 1931 ali CIE 1964.
