IS - Unsharp/Brighten Filter

The Unsharp/Brighten Filter automatically sharpens the text and brightens the contrast of the image,
making text more readable. This is similar to the Image Adaptive Text Filter, however it brightens the
image as well. You should test both image processing techniques to determine which filter works best
for your environment.
Note: The Unsharp/Brighten Filter should not be used concurrently with the
Filter.

J - JPEG Image Quality

Sets the desired quality when the JPEG image format is selected. Higher numbers result in higher
quality, but larger files. Smaller numbers result in greater amounts of lossy compression, faster
transmission times, lower quality, but smaller files. (Default = 50)
n J Image is compressed as much as possible while preserving quality factor of n ( n = 0 - 100)
0J worst quality (smallest file)
100J best quality (largest file)

K - Gamma Correction

Gamma measures the brightness of midtone values produced by the image. You can brighten or
darken an image using gamma correction. A higher gamma correction yields an overall brighter
image. The lower the setting, the darker the image. The optimal setting for text images is 50K.
0K Gamma correction off (default)
50K Apply gamma correction for brightening typical document image
n K Apply gamma correction factor n ( n = 0-1,000)
