2.5.2 Other Color Dropout Options
Advanced Processing provides two options that can adjust your scanned image in the best
optimal result.
Filter
Threshold
This value is used to determine the color which will be dropped out. A lower
value will drop more of the selected color out, while a higher value will leave
more of the selected color in.
Background
Level
The pixel which is higher than the background value will be adjusted to the
lightest point. Adjust the value for both the Filter Threshold and Background
Level to produce the best optimal result.
Example, slightly adjusting the background value makes your text more clear.
Original
