Gamma
Through the Gamma control, you can adjust the light intensity scale between the
original image and output image so that when the image is reproduced on some
devices, the tones in the reproduced image may be closer to those in the original
image.
Compression
When built-in compression hardware is present, this control allows you to select
the type of compression that will be recorded in the image’s Settings file, for use
when scanning directly to a file. Note that images scanned to a displayed window
will not be compressed.
Photo Invert
Selecting this control will let you scan the “negative” of your images.
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.
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.
