* About Gamma correction
Gamma (
γ
) is a value representing a responsiveness characteristic of
image contrast. Every input and output device of image data has its
own Gamma value; the overall Gamma value must be corrected to be
equal to 1. If a CRT monitor has a Gamma value of 2.2, for example,
the value for this unit must be corrected to 0.45 (2.2 x 0.45
≈
1).
