Contrast
The Contrast option sets the image contrast by adjusting the difference
between black and white, thereby making an image sharper or softer.
In a low-contrast setting, the difference between black and white is
small, so the image is softer. In a high-contrast setting, the difference
between black and white is large, so the image is clearer. Select a
contrast value from 1-255. The default is 128.
Contrast 51 Contrast 128 Contrast 205
Adjust the contrast setting by dragging the Contrast sliding bar in the
Front Side Settings or Back Side Settings group box. Or you can type
a value (1-255) in the
Contrast
text box. Scan the document to check
the contrast.
