3S ship every 3rd pixel, both horizontally and vertically
U - Document Image Filter: Sharpens the edges and smooths the area
between the edges of the transmitted text image. The Document Image
Filter enhances images of documents such as ID cards and prescriptions.
This filter should be used with gamma correction (see
page 7-6
), with
the imager 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 7-8
). This filter also works well
when shipping pure black and white images (1 bit per pixel). The opti-
mal setting is 26U.
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 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 concen-
trated 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.
0W Don’t ship histogram
(default)
1W Ship histogram
