The brightness control defines the resulting brightness of the image. A lower value results
in darker images, a higher value results in brighter images.
Values close to 0% or 100% may result in unwanted artifacts.
B.4.2.1.2 Contrast
The contrast control defines the contrast of the image. A lower value results in an image
that is smoother, a higher value shows more details and the image will become crisper.
Values close to 0% or 100% may result in unwanted artifacts.
B.4.2.1.3 Gamma
The gamma control defines the gamma correction used by the scanner camera. A value
of 1,6 is a good approximation. The range of values are from 0 (no gamma) to 2,5
(maximum gamma).
A higher gamma value shows more details in darker areas and compresses bright areas.
