    en.wikipedia.org/wiki/Gamma_correction

    For a CRT, the gamma that relates brightness to voltage is usually in the range 2.35 to 2.55; video look-up tables in computers usually adjust the system gamma to the range 1.8 to 2.2, [1] which is in the region that makes a uniform encoding difference give approximately uniform perceptual brightness difference, as illustrated in the diagram at ...

    As a measure of light emitted per unit area, this unit is frequently used to specify the brightness of a display device. The sRGB spec for monitors targets 80 cd/m 2 . [ 3 ] Typically, monitors calibrated for SDR broadcast or studio color grading should have a brightness of 100 cd/m 2 . [ 4 ]

    The favored aspect ratio of mass-market display industry products has changed gradually from 4:3, then to 16:10, then to 16:9, and has now changed to 18:9 for smartphones. [7] [needs update] The 4:3 aspect ratio generally reflects older products, especially the era of the cathode ray tube (CRT).

    The proof runs through in almost the same way as that of channel coding theorem. Achievability follows from random coding with each symbol chosen randomly from the capacity achieving distribution for that particular channel.

    en.wikipedia.org/wiki/Luminous_intensity

    Prior to the definition of the candela, a variety of units for luminous intensity were used in various countries. These were typically based on the brightness of the flame from a "standard candle" of defined composition, or the brightness of an incandescent filament of specific design.

  9. Lux - Wikipedia

    en.wikipedia.org/wiki/Lux

    The lux (symbol: lx) is the unit of illuminance, or luminous flux per unit area, in the International System of Units (SI). [1] [2] It is equal to one lumen per square metre.In photometry, this is used as a measure of the irradiance, as perceived by the spectrally unequally responding human eye, of light that hits or passes through a surface.
