Luminance while imaging luminance meters measure luminance in a way similar to the way a digital camera records color images. Luminance 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 that passes through, is emitted or reflected from a particular area, and falls within a given solid angle. The SI unit for luminance is candela per square metre (cd/m). A non-SI term for the same unit is the nit. The CGS unit of luminance is the stilb, which is equal to one candela per square
Maximising measure under "T", i.e., for every Borel-measurable subset "A" of "X", "μ"("T"("A")) = "μ"("A"). (Note that, by the Krylov-Bogolyubov theorem, if "X" is compact and metrizable, Inv("T") is non-empty.) Define, for continuous functions "f" : "X" → R, the maximum integral function "β" by A probability measure "μ" in Inv("T") is said to be a maximising measure for "f" if Maximising measure In mathematics — specifically, in ergodic theory — a maximising measure is a particular kind of probability measure. Informally, a probability measure "μ" is a maximising measure for some function "f" if the integral of "f" with respect to
