.
Dynamic
Threshold:
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 for scanning mixed
documents containing faint text, shaded
backgrounds, or color backgrounds 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.
