Auto Area Segmentation
Makes black and white images clearer and text recognition more accurate by separating the text from
the graphics.
Threshold
Adjusts the level at which black areas in text and line art are delineated, improving text recognition in
OCR (Optical Character Recognition) programs.
Color Enhance
Enhances the shades of the color you select in the scanned image. This setting is available only if you
select
Grayscale
or
Black & White
as the Image Type setting.
Brightness
Adjusts the overall lightness and darkness of the scanned image.
Contrast
Adjusts the difference between the light and dark areas of the overall scanned image.
Gamma
Adjusts the midtone density of the scanned image.
Unsharp Mask
Makes the edges of certain image areas clearer. Turn off this option to leave softer edges.
Descreening
Removes the ripple pattern that might appear in subtly shaded image areas, such as skin tones. This
option improves results when scanning magazines or newspapers. (The results of descreening do not
appear in the preview image, only in your scanned image.)
Skip Blank Pages
If the scanner detects marks from the other side of a blank page and adds the marks to the scanned
image, adjust this setting to prevent this.
Edge Fill
Corrects shadowing around the edges of the image by filling the shadows with black or white.
Correct Document Skew
Corrects skewed originals, image contents, or both.
