The color swatches represent the color of each white point, ... light white fluorescent F7 0.31292 ... 0.32960 6500 D65 simulator, daylight simulator F8 0.34588: 0. ...
The CIE positions D65 as the standard daylight illuminant: [D65] is intended to represent average daylight and has a correlated colour temperature of approximately 6500 K. CIE standard illuminant D65 should be used in all colorimetric calculations requiring representative daylight, unless there are specific reasons for using a different illuminant.
The projection system uses a simple 2.6 gamma curve, the nominal white luminance is 48 cd/m 2 (14ftL), and the white point is based on a projector with a xenon bulb, for a correlated color temperature (CCT) of ~6300 K. It is incorrect to refer to this as "D63" as this white point is not a CIE standard illuminant, and is not on the Planckian ...
ITU-R Recommendation 709, usually abbreviated Rec. 709, BT.709, or ITU-R 709, is a standard developed by the Radiocommunication Sector of the International Telecommunication Union (ITU-R) for image encoding and signal characteristics of high-definition television (HDTV). [3]
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
ITU-R Recommendation BT.2020, more commonly known by the abbreviations Rec. 2020 or BT.2020, defines various aspects of ultra-high-definition television (UHDTV) with standard dynamic range (SDR) and wide color gamut (WCG), including picture resolutions, frame rates with progressive scan, bit depths, color primaries, RGB and luma-chroma color representations, chroma subsamplings, and an opto ...
This diagram is a retouched picture, which means that it has been digitally altered from its original version.Modifications: Added information on DCI-P3 color space and D65 white point.
Not all wavelengths of light are equally visible, or equally effective at stimulating human vision, due to the spectral sensitivity of the human eye; radiation in the infrared and ultraviolet parts of the spectrum is useless for illumination. The luminous efficacy of a source is the product of how well it converts energy to electromagnetic ...
