In mathematics, the common logarithm is the logarithm with base 10. It is also known as the decadic logarithm and as the decimal logarithm, named after its base, or Briggsian logarithm, after Henry Briggs, an English mathematician who pioneered its use, as well as standard logarithm. Historically, it was known as logarithmus decimalis or logarithmus decadis. It is indicated by log₁₀(x), or sometimes Log(x) with a capital L (however, this notation is ambiguous since it can also mean the complex natural logarithmic multi-valued function). On calculators, it is usually "log", but mathematicians usually mean natural logarithm (logarithm with base e ≈ 2.71828) rather than common logarithm when they write "log". To mitigate this ambiguity, the ISO 80000 specification recommends that log₁₀(x) should be written lg(x) and logₑ(x) should be ln(x).

An image display apparatus is provided that avoids discontinuity in a high luminance and gradation range and is capable of displaying gradations where differences in sense of luminance change at equal intervals from an intermediate gradation range to the maximum value of the gradations. A gradation / light emission luminance converter(104) converts the gradation of an input image into data corresponding to a luminance to be displayed by a video light emitter(107) using predetermined conversion characteristics. In an intermediate gradation range, the common logarithms of the luminance to be displayed by the video light emitter(107) have a proportional relation to the gradations. In the high luminance and gradation range, the relation gradually deviates from the proportional relation; the nearer the gradation approaches the maximum value thereof, the larger the variation quantity of the common logarithm of the luminance to be assigned to an increment of the gradations becomes.
