A unit which indicates the changes in the brightness of an image. It is expressed as a function of the electric input power to
devices (e.g. scanner, display) and the brightness of the image. If the gamma rate is larger than 1, the brightness of an
image increases and vice versa. To reproduce the brightness of a document as the same as the brightness of the actual
document, set the gamma rate to 1.
