Cie standard illuminants
| Цветоделение |
Known spectral data established by the cie for four different types of light sources. when using tristimulus data to describe a color, the illuminant must also be defined. these standard illuminants are used in place of actual measurements of the light so

Measurement, английский
- Set of operations having the object of determining a value of a quantity (1)
- Измерение. система мер.
- Измерение; замер
- The size, length, etc. of something which has been measured
- Измерение
- Обмер
- Оценка
- Измерение dust ~ измерение концентрации пыли
- Измерение. комплекс операций, имеющих целью определение значе-ния величины [32].
- The process of ascertaining the attributes, dimensions, extent, quantity, degree or capacity of some object of observation and representing these in the qualitative or quantitative terms of a data language. any empirical pursuit that places the observer outside his object of observation must consider measurement the fundamental process through which scientific constructs or models are linked to reality (->index, ->symptom). otherwise measurement is only one section in a circular process of computing a stable form. the traditional levels of measurement are nominal, ordinal, interval and ratio scales.
- The magnitude of the property of an object calibrated against one or more units of measure.
- Измерение. комплекс операций, имеющих целью определение значения величины [32].

Cie standard observer, английский
A hypothetical observer having the tristimulus color mixture data recommended in 1931 by the cie for a 2° viewing angle. a supplementary observer for a larger angle of 10° was adopted in 1964. if not specified, the 2° standard observer should be assumed.
Cie (commission international de l'eclairage), английский
A french name that translates to international commission on illumination, the main international organization concerned with color and color measurement.
