The
output gamma curve can be set manually.

Each color channel can be set individually, or
the same value can be set for all the RGB
channels by selecting “RGB”.

When you click on the line, a point appears, and
you can modify the curve by dragging that
point around.
•
If you check the grayscale check box on the
Color Adjustment offset menu, only the
grayscale channel is enabled.

Use this dialog box to set the color balance,
intensity and brightness.

If you check the grayscale check box, data is
output in monochrome gray.
“Unsharp Mask”
•
Sharpens the image by selectively adjusting the
contrast.
•
Amount:
Sets the level of unsharp masking.
•
Threshold:
Applies unsharp mask when the variation from

Entering a low threshold value applies unsharp mask even to areas with low levels of
image contrast, while a setting of 0 applies unsharp mask to the entire image.
