Contrast

You can adjust the contrast for the whole image. If you increase the contrast, the bright areas become brighter, and
the dark areas become darker. On the other hand, if you lower the contrast, the differences between the bright and
dark areas of the image are less defined.
Note:
This feature is not available depending on the settings on the Main Settings tab > Image Type or the settings on the
Advanced Settings tab.

Gamma

You can adjust the gamma (brightness of the intermediate range) for the whole image. If the image is too light or
too dark, you can adjust the brightness.
Note:
This feature is not available depending on the settings on the Main Settings tab > Image Type or the settings on the
Advanced Settings tab.

Threshold

You can adjust the border for monochrome binary (black and white). Increase the threshold, the black color area
becomes larger. Decrease the threshold, the white color area becomes larger.
Note:
This feature may not be available depending on the settings on the Main Settings tab > Image Type or the settings on the
Advanced Settings tab.
