What is CIE chromaticity diagram?
What is CIE chromaticity diagram?
The chromaticity diagram is thus a normalized plot of the color response of the CIE 1931 standard observer. Each point on the curved boundary line in Figure 6.4–5 is plotted from the tristimulus values that result from a single-wavelength stimulus.
What is CIE 1931 chromaticity diagram?
The chromaticity diagram illustrates a number of interesting properties of the CIE XYZ color space: The diagram represents all of the chromaticities visible to the average person. These are shown in color and this region is called the gamut of human vision.
What does CIE stand for in color?
The CIE color model is a color space model created by the International Commission on Illumination known as the Commission Internationale de l’Elcairage (CIE). It is also known as the CIE XYZ color space or the CIE 1931 XYZ color space.
What does the CIE curve show and describe?
The CIE system characterizes colors by a luminance parameter Y and two color coordinates x and y which specify the point on the chromaticity diagram. Based on the fact that the human eye has three different types of color sensitive cones, the response of the eye is best described in terms of three “tristimulus values”.
What is the purpose of CIE?
Commission internationale de l’éclairage (CIE) is a 100 year old organization that creates international standards related to light and color.
How do you calculate CIE chromaticity coordinates?
The calculation of the CIE chromaticity coordinates for a given colored object requires the multiplication of its spectral power at each wavelength times the weighting factor from each of the three color matching functions.
How do you test chromaticity?
A spectrophotometer is used to determine the chromaticity value of water samples by establishing the correlation between the absorbance value of a standard chromaticity solution at a characteristic wavelength or the peak area of the absorption spectrum and the chromaticity value.
What is chromaticity in biology?
Chromaticity is an objective specification of the quality of a color regardless of its luminance. Chromaticity consists of two independent parameters, often specified as hue (h) and colorfulness (s), where the latter is alternatively called saturation, chroma, intensity, or excitation purity.
What is CIE color model?
The CIE color model is a color space model created by the International Commission on Illumination known as the Commission Internationale de l’Elcairage (CIE).
What is CIE 1976 Lab color space?
The CIE 1976 L*a*b* color space (also referred to as CIELAB) is one of the most popular color spaces for measuring object colors . It was defined by CIE in 1976 for color communication and is widely adopted today in many industries for color control and management.
What does chromaticity mean?
Chromaticity is an objective specification of the quality of a color regardless of its luminance.
