8 - 2 IMAGETEAM™ 4600/4800 User’s Guide
G - Gain: This modifier boosts the signal and multiplies the pixel value.
1G No gain (default)
2G Medium gain
4G Heavy gain
8G Maximum gain
D - Delta for Acceptance: This sets the allowable range for the white value
setting (see W - Target White Value). Delta is only available when using Photo
Style.
(Default = 25)
nD Range: 0 - 255
L - LED State: Determines if the LEDs should be on or off, and when.
Ambient illumination (0L) is preferred for taking pictures of color documents,
such as ID cards, especially when the imager is in a stand. LED illumination
(1L) is preferred when the imager is hand held. LED State is not available
when using Decoding Style.
0L LEDs off (default)
1L LEDs on
T - Wait for Trigger: Waits for a hardware trigger pull before taking the image.
0T Takes image immediately
(default)
1T Waits for a trigger pull, then takes the image
U - Update Tries: The maximum number of frames the imager should take to
reach the Delta for Acceptance. Update Tries is only available when using
Photo Style.
(Default = 6)
nU Range: 0 - 10
W - Target White Value: Sets the target for the median grayscale value in the
captured image. For capturing close-up images of high contrast documents,
a lower setting, such as 75, is recommended. Higher settings result in longer
exposure times and brighter images, but if the setting is too high, the image
may be overexposed. Target White Value is only available when using Photo
Style.
(Default = 125)
nW Range: 0 - 255
% - Target Set Point Percentage: Sets the target point for the light and dark
values in the captured image. A setting of 75% means 75% of the pixels are
at or below the target white value, and 25% of the pixels are above the target
white value. Altering this setting from the default is not recommended under
normal circumstances. To alter grayscale values, Target White Value should
be used.
(Default = 50)
n% Range: 1 - 99
Image Ship - IMGSHP
An image is taken whenever the trigger of the IT4600/4800 is pressed, or when
the Image Snap (IMGSNP) command is processed. The last image is always
stored in memory. You may “ship” the image by using the IMGSHP command.
