Bayer dither scan - Close up
Advanced Panel Options
The options in this panel may also appear in the Main panel, but with additional settings for you to fine-tune the
feature you've selected.
Despeckle
This option removes speckles from the background. Speckles are small spots on an image that the scanner
interpreted as a valid part of the document. For example, an irregularity in the paper, a small wrinkle, or holes where
a staple was removed may show up as speckles in the scanned image. The Despeckle option identifies these spots
and removes them. This option is only available when scanning in black and white.
Radius—this is the size of the area that is evaluated for stray dots.
Number—this is the maximum number of dots within the radius that should be considered a speckle. If this number
of dots are in the circle, the dots will not be considered a speckle and remain in the image. If there are less than this
number of dots in the circle, the dots are considered a speckle and removed from the image.
