* 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 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).
