Edge
Fill
Check White or Black if you wish to add white or black edge on the
border of your scanned image. Enter the value from 0 to 5 mm.
Default value is 0.
Original
Edge Fill: 5mm (Black)
If you want to add a white or black frame on the edges of the
scanned image, check "Edge Extension".
The default value is 0. The maximum value is half of the short side
of the selected scan area.
For example, if you choose an A4 size (8.26 "X11.69"), then the
maximum value of the white or black box is 4.14" (half of "8.26").
Despeckle
Occasionally small dots or specks appear in the background of a scanned image. Remove
unwanted speckles provides a cleaner image for OCR (Optical Character Recognition)
processing, and also helps to reduce compressed file size.
Define the speckles (also known as image noise) you wish to remove by specifying its number
(size) and radius (range). The measuring unit is pixel. The higher the number, the more
speckles will be removed.
Before Despeckle

The function is currently available for Black and White image only.
To scan at rated speed, it is recommended to set the noise radius up
to 10 pixels.
