Color dropout
—color dropout is the ability of your scanner to automatically remove a
color from a scanned image. For example, if you are scanning a letter with a red
watermark, you can choose to filter out the red so the scanned letter just shows the
text and not the red watermark. Color dropout applies to Black & White or Grayscale
scanning modes.

Bit depth reduction
—Click the drop down menu and select an option from the list.
The Bit depth reduction options are only available when scanning in black and white.
Error diffusion
,
Bayer
, and
Halftone
patterns are the intentional application of noise
(dithering) in the image to help alleviate banding when scanning in binary (black and
white) mode. For example, if you scan a color photo in black and white, the image file
will have large blocks of black and white and the image barely recognizable. Dithering
the image creates a black and white image that is recognizable.
Dynamic threshold
attempts to evaluate the scanned page and automatically adjust
the brightness and contrast levels to produce the best quality image when scanning in
black and white.
