Perform Color Correction
Apply color correction to the image so the displayed colors approximate the original item colors. Select
this option to use the scanner's default Gamma table which has been calibrated to produce the best
quality color results for your scanner. When this option is not selected, the resulting scans will be dark
and the brightness, contrast, and gamma options will require a greater amount of adjustment to affect
the overall lightness of the image.

Despeckle
This option removes speckles from the background. Speckles are small spots on an image that the

Radius
—this is the maximum number of dots within the radius that should be considered a speckle. If
Number
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.
