Image Settings -
Enhancements tab
The options available on the Enhancements tab depend on the
Scan as
selection on the General tab.
Blank Image Detection
— allows you to configure the scanner to
eliminate blank images.
•
On
: turns Blank Image Detection on and makes the rest of the Blank
Image Detection options available.
•
Delete if file size is less than
: allows you to select the minimum
image size that the scanner will consider to be non-blank. Any image
that is less than this value will be considered blank and will not be
given to the scanning application. The values range from 1 to 1000
KB (1 KB equals 1024 bytes).
Color Dropout
— used to eliminate a form's background so that only
the entered data is included in the electronic image (i.e. remove the
form's lines and boxes). For black and white images, these settings
effect the grayscale version of the document which the scanner
analyzes to produce that electronic image.
•
Color
: select the desired dropout color. Options are:
(none), Red,
Green,
and
Blue
.
•
Filter Threshold:
allows you to adjust how the scanner identifies the
color to be dropped. The values range from 0 to 255. Default: 175.
•
Background:
allows you to select the grayscale value to replace the
dropped color with. It is suggested that this value be higher than the
Threshold value selected on the Adjustments tab in order for the
dropped color to appear to be part of the background. The values
range from 0 to 255. Default: 245.
NOTE: The Color Dropout options are only available when the
Scan as
selection is
Black and White
.
