Selecting
Dynamic Threshold
allows the scanner
to dynamically evaluate each document
to determine the optimal threshold value
to produce the highest quality image.
This is used to scan mixed document
containing faint text, shaded background,
or color background with a single setting.
If Dynamic Threshold is selected,
Threshold, Brightness, and Contrast are
not available.
Sensitivity of Dynamic Threshold
Occasionally your scanned image may
contain small dots or speckles. To remove
these spots, increase the sensitivity value
by moving the bar to the right. The value
ranges from 1 to 30. The default is 20.
