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. Select the Advanced source configuration mode to show
this panel.

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. 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.
For example, if the radius is 3 and the number is 5, then the document is evaluated in sections of
3x3 pixels and if there are more than 5 stray dots within a 3x3 area, they are not considered a
speckle.

Filter

Use the Filter option to increase or decrease the sharpness in the scanned image. Click the drop
down menu and select an option from the list.
Blur—softens the appearance of the image by evaluating a pixel and changing its color to an
•
average of the surrounding pixels. Use the Radius field to set the size of the area for each pixel
to be evaluated to adjacent pixels. Note that the higher the number is in the Radius field, the
longer it will take the driver to evaluate the image
