The CIE luminosity function or is a standard function established by the Commission Internationale de l ' Éclairage ( CIE ) and may be used to convert radiant energy into luminous ( i. e., visible ) energy.

Often, in practice, the white point is assumed to follow a standard and is not explicitly stated ( e. g., for " absolute colorimetric " rendering intent ICC L * a * b * values are relative to CIE standard illuminant D50, while they are relative to the unprinted substrate for other rendering intents ).

All liveries are covered ( Black & Tan, CIE Golden Brown, Irish Rail and Iarnród Éireann ) and with correct detailing for each era ( e. g. LED pilot lights on the later versions ).

Pupils who plan to study further would usually sit for the exam organised by the higher education institutes, or international assessment bodies like Edexcel, CIE and College Board, or the related government bodies in mainland China and Taiwan.

The College of International Education ( CIE ) at Tianjin University of Technology ( TUT ) is a school established especially for recruiting international students who want to study abroad in China.

Sir William Wilson Hunter KCSI CIE ( 15 July 1840 – 6 February 1900 ) was a Scottish historian, statistician, a compiler and a member of the Indian Civil Service, who later became Vice President of Royal Asiatic Society.

Briefly, the specification calls for picture encoding using the ISO / IEC 15444-1 " JPEG2000 " (. jp2 ) standard and use of the CIE XYZ color space at 12 bits per component encoded with a 2. 6 gamma applied at projection, and audio using the " Broadcast Wave " (. wav ) format at 24 bits and 48 kHz or 96 kHz sampling, controlled by an XML-format Composition Playlist, into an MXF-compliant file at a maximum data rate of 250 Mbit / s.

The CIE coordinates for the colors of the 9th edition of the Standard Color Card were formally specified in JOSA in 1946.

This color is approximately equivalent to the color of the CIE chromaticity diagram at the 430 nanometer line.

The primaries and the CIE Standard Illuminant D65 | D65 white point of sRGB are shown.

This tone of violet -- an approximation of the color violet at about 417 nanometers as plotted on the CIE chromaticity diagram -- is shown at right.

It is an approximation of the color violet at about 400 nanometers as plotted on the CIE chromaticity diagram.

When plotted on the CIE chromaticity diagram, it can be seen that this is a hue corresponding to that of a visual stimulus of approximately 380 nm on the spectrum.

According to the CIE ( the International Commission on Illumination ), reflectivity is distinguished from reflectance by the fact that reflectivity is a value that applies to thick reflecting objects.

Brigadier Sir Robert Eric Mortimer Wheeler CH, CIE, MC, FBA, FSA ( 10 September 1890 – 22 July 1976 ), was one of the best-known British archaeologists of the twentieth century.

In opponent color spaces in which two of the axes are perceptually orthogonal to lightness, such as the CIE 1976 ( L *, a *, b *) ( CIELAB ) and 1976 ( L *, u *, v *) ( CIELUV ) color spaces, hue may be computed together with chroma by converting these coordinates from rectangular form to polar form.

The Daewoo part in the joint venture was bought out by Swiss venture Hirsch & CIE in 2003.

The best-known measure of metamerism is the Color Rendering Index ( CRI ), which is a linear function of the mean Euclidean distance between the test and reference spectral reflectance vectors in the CIE 1964 color space.

A newer measure, for daylight simulators, is the MI, CIE Metamerism Index which is derived by calculating the mean color difference of eight metamers ( five in the visible spectrum and three in the ultraviolet range ) in CIELAB or CIELUV.

The CIE 1931 color space chromaticity diagram with wavelengths in nanometer s. The colors depicted depend on the color space of the device on which the image is viewed.

The International Commission on Illumination ( usually abbreviated CIE for its French name, Commission internationale de l ' éclairage ) is the international authority on light, illumination, color, and color spaces.

* Building on the Optical Society of America's report on colorimetry in 1922, the CIE convened its eighth session in 1931, with the intention of establishing an international agreement on colorimetric specifications and updating the OSA's 1922 recommendations based on the developments during the past decade.

The meeting, held in Cambridge, United Kingdom, concluded with the formalization of the CIE 1931 XYZ color space and definitions of the 1931 CIE 2 ° standard observer with the corresponding color matching functions, and standard illuminants A, B, and C.

* In 1964 the 10 ° CIE standard observer and its corresponding color matching functions as well as the new standard daylight illuminant D6500 were added, as well as a method for calculating daylight illuminants at correlated color temperatures other than 6500 kelvin.

* CIE 1931 color space, one of the first mathematically defined color spaces, created by the International Commission on Illumination ( CIE ) in 1931.
