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.
Image Processing Circuit Board
The optional Image Processing Circuit Board offers a number of image
processing features for the Fujitsu M3096G/H and M3097G scanners. The board
is shipped separately from the scanner and should be installed by a
Fujitsu-authorized and trained service technician.
The IPC board offers the following image enhancement options:
• Photo Invert
• Horizontal Mirror
• Automatic Discrimination
• Outline Extraction
• Edge Emphasis
• Dynamic Thresholding (see “Threshold” above)
If the board is not installed, these options will be disabled.
Photo Invert
Selecting this control will let you scan the “negative” of your images.
