Horizontal Mirror
This option allows you to do a scan which mirrors the image over a vertical axis
down the center of the image, thus reversing the image left-to-right. Note that in
portrait mode, this axis cuts through the narrower sides, while in landscape
mode, it cuts through the wider sides.
Automatic Discrimination
The automatic discrimination feature is useful when scanning documents
containing both photos and text. This feature allows the scanner to switch
between text and photo mode in one pass. Line mode scanning is binary and
photo mode is dithered halftone. The end result is that line art and photos are both
processed for their best appearance. The automatic discrimination feature
analyzes the reflected light from the page to determine if it is black and white
(very high or low signal) or gray scale (varying signal). When high signal
fluctuations are detected, the scanner switches to line mode for black and white.
When fluctuations are gradual, the scanner switches to halftone mode for
scanning a photograph.
Outline Extraction
The Outline feature saves the outline of a black and white image. The scanner
looks for the boundaries between black and white and connects them to form
outlines of the objects in the image.
Edge Emphasis
The edge emphasis feature enhances the edges of the image to make them appear
sharp and crisp. It can also be set to “smoothing” to help eliminate spot noise and
voids.
Scanner Reports
This is a small text display area that shows information about the scanner you are
using. Information here will include ROM version information and other
information that particular scanner models report about themselves.
