* About Gamma correction
Gamma ( ) 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
