U - Document Image Filter
Allows you to input parameters to sharpen the edges and smooth the area
between the edges of text in an image. This filter should be used with gamma
correction (see page 154), with the scanner in a stand, and the image captured
using the command:
IMGSNP1P0L168W90%32D
This filter typically provides better JPEG compression than the standard E - Edge
Sharpen command (see page 150). This filter also works well when shipping pure
black and white images (1 bit per pixel). The optimal setting is 26U.
0U
26U
n U
Document image filter off (default)
Apply document image filter for typical document image
Apply document image filter using grayscale threshold n. Use lower
numbers when the image contrast is lower. 1U will have a similar
effect to setting E - Edge Sharpen (page 150) to 22e. Range: 0-255.
Example:
Document Image Filter set to 0U: Document Image Filter set to 26U:
V - Blur Image
Smooths transitions by averaging the pixels next to the hard edges of defined
lines and shaded areas in an image.
