This filter typically provides better JPEG compression than the standard E -
Edge Sharpen command (see page 8-6). This filter also works well when
shipping pure black and white images (1 bit per pixel). The optimal 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 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.
0W Don’t ship histogram
(default)
1W Ship histogram
Image Size Compatibility
If you prefer that an image ship returns images at the sensor’s native resolution
(752x480 pixels for the 5X00 engine, 640x480 pixels for the 4X00 engine), scan
the Native Resolution code. If you have an 4X00 image engine and have
designed applications that expect an image ship to return exactly 640x480
pixels, scan the Force VGA Resolution bar code. Refer to
"Show Engine
Revision"
on page 11-1 for information on determining the engine in your unit.
