A.12.9 Image Control Screen

The parameters are set in two screens named Image Control 1 and Image Control 2.
A.12.9.1 Image Control 1
In general:
• Tap the + or – to change the values in steps of one.
• Tap the + or – and hold for at least five steps, then the value changes in steps of five.
A.12.9.1.1 Brightness
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.
A.12.9.1.2 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.
A.12.9.1.3 Gamma
The gamma control defines the gamma correction used by the scanner camera. A value
of 1,7 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.
