Image Processing Options

DocuMate 765 Scanner User's Guide
The Main tab has the basic features you need for image capture when
scanning. The basic settings include color mode, resolution (dpi),
brightness, contrast, and dither options. The options on the Image
Processing tab are advanced image capture options for improving the
quality of the scanned image, or just modifications such as removing
watermarks.
Extra Features—the options in this section will be enabled if the
scanning software supports the feature.
• White Level From Paper—this option uses white as the reference
color when the documents being scanned are on colored paper.
When colored paper is scanned, the resulting image may be filled
with a lot of noise and the image quality will be poor.
This option will not work properly if the paper being scanned has
multiple background colors on each page, or if the color intensity
varies across the page.
This option will be disabled if you are scanning in Color Mode, or you
have selected the options for AutoCrop, Deskew or Margin.
• Automatic Separation—this option enables the scanner to
automatically differentiate between text areas and photo areas on a
page. Text areas are scanned in Binary (Black and White) mode,
while the photo areas are scanned using the Dither (halftone) pattern.
In some cases, it may not be possible to separate the text and images
completely using this automatic feature. If you often scan documents
where the image area is always at the same part of the page you can
get better results by creating a Sub Area. Please see "Page Layout
Sub Area" on page 77 for more information.
The Automatic Separation option is only available in Black and White
color mode. This feature will automatically be disabled if Noise
Reduction, Sub Area, Dynamic Threshold, Automatic Crop or
Deskew are enabled.
