Historically gamma correction was used to correct the illumination behavior of
CRT displays, by compensating brightness-to-voltage with a gamma value
between 1,8 up to 2,55.

The gamma algorithms for correction can simplify resolution shifting as shown
seen below.

Input & output signal range from 0 to 1

Output-signal = Input-signal

Gamma

Fig.: 5-22: Several gamma curves comparable to a LUT

Gamma values less than 1.0 map darker image values into a wider ranger.

Gamma values greater than 1.0 do the same for brighter values.

INFO

Gamma algorithm is just a way to generate a LUT. It is not implemented in the
camera directly.
