To adjust the brightness value between 1 and 255.
A high brightness setting results in a lighter overall image. A low brightness setting
results in a darker overall image.
When scanning a dark image, the darker area may appear as deep black although it
has gray shades. In this case, increase the setting and shades of gray appear.
Conversely, if a lighter image becomes pure white, decrease the setting.
Lower
To adjust the contrast value between 1 and 255.
At a high contrast setting, the scanner emphasizes black and white, leaving few
middle gray shades. At a low contrast setting, the scanner emphasizes the middle
gray shades, at the expense of black and white.
If you want a sharp image, set a higher value. If you want a soft image, set a lower
value.
