standard illuminant उदाहरण वाक्य
उदाहरण वाक्य
- Although there is generally no one-to-one correspondence between illuminants and white points, in the case of the CIE D-series standard illuminants, the spectral power distributions are mathematically derivable from the chromaticity coordinates of the corresponding white points.
- In reflection mode, this is often ( but not always ) taken as the of the 2?observer and standard illuminant C,, . ) Equations for " u " 2 and " v " 2 are given below:
- The tri-stimulus value Y gives a measure of the lightness of the material as defined in ISO 7724-2 requiring a 45?/ 0?geometry to be used with standard illuminant C and 2?observer ( although it is mentioned that slightly different conditions will not result in significant errors ).
- To deal with the problem of having to compare light sources of different correlated color temperatures ( CCT ), the CIE settled on using a reference black body with the same color temperature for lamps with a CCT of under 5000 K, or a phase of CIE standard illuminant D ( daylight ) otherwise.
