Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light...

Relative luminance Y {\displaystyle Y} follows the photometric definition of luminance L {\displaystyle L} including spectral weighting for human vision...

in video engineering and relative luminance as used in color science (i.e. as defined by CIE). Relative luminance is formed as a weighted sum of linear...

Look up luminance in Wiktionary, the free dictionary. Luminance is a photometric measure of the density of luminous intensity in a given direction, measured...

calculated from gamma-corrected RGB input and that it is different from true luminance. Today, the term YUV is commonly used in the computer industry to describe...

Luminance HDR, formerly Qtpfsgui, is graphics software used for the creation and manipulation of high-dynamic-range images. Released under the terms of...

brightness and color accuracy. The "luminance contrast" is the ratio between the higher luminance, LH, and the lower luminance, LL, that define the feature to...

logarithmically, it is helpful to have an appreciation of both illuminance and luminance by orders of magnitude. To help compare different orders of magnitude...

Lightness is a visual perception of the luminance ( L ) {\displaystyle (L)} of an object. It is often judged relative to a similarly lit object. In colorimetry...
