3S ship every 3rd pixel, both horizontally and vertically
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 fil-
ter should be used with gamma correction (see
page 1-9 ), 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 1-11 ).
This filter also works well when shipping pure black and white images (1 bit per pixel). The optimal setting is 26U.
Note: If you want to use an automatic image filter, rather than changing these settings manually, refer to IU - Image Adaptive
Text Filter (page 1-8).
0U Document image filter off (default)
26U Apply document image filter for typical document image
n U 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 1-6) to 22e. Range: 0-255.
V - Blur Image
Smooths transitions by averaging the pixels next to the hard edges of defined lines and shaded areas in an image.
0V Don’t blur (default)
1V Blur
W - Histogram Ship
A histogram gives a quick picture of the tonal range of an image, or key type. A low-key image has detail concentrated in
the shadows; a high-key image has detail concentrated in the highlights; and an average-key image has detail concentrated
in the midtones. This modifier ships the histogram for an image.
