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.

EDUCTION
Moiré patterns are wavy or rippled lines that may appear in the scanned images of newspapers and magazines,
and sometimes scanned images of photos, line drawings, and color scans of textured paper. Select the
Moiré
reduction
option to have the driver attempt to find and remove moiré patterns from the image. Please note that
when Moiré reduction is enabled the scanner may scan slower as the image is checked for moiré patterns. This
option is only available when scanning in
Color
or
Gray
.
Moiré radius
—you can set the size of the area to be evaluated in the Moiré radius field. Adjusting the radius will
produce different results for the various types of items that can be scanned. With this feature, you may have to
test scan a few times, adjusting the Moiré radius as needed, until you obtain the best results for the type of paper
in your scan job. Note that the higher the number is in the Moiré radius field, the longer it will take the driver to
evaluate the image.
