W - Target White Value
Sets the target for the median grayscale value in the captured image. For capturing close-up images of high contrast doc-
uments, 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
(1P).
(Default = 125)
nW Range: 0 - 255
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 (1P). (Default = 25)
nD Range: 0 - 255
U - Update Tries
This sets the maximum number of frames the scanner should take to reach the D - Delta for Acceptance . Update Tries is
only available when using Photo Style (1P). (Default = 6)
nU Range: 0 - 10
% - 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,
W - Target White Value should be used.
(Default = 50)
n% Range: 1 - 99
Step 2 - Ship a Picture Using IMGSHP
Image Ship - IMGSHP
An image is taken whenever the button is pressed, or when the Image Snap (IMGSNP) command is processed. The last image
is always stored in memory. You can “ship” the image by using the IMGSHP command.
The image ship commands have many different modifiers that can be used to change the look of the image output. Modifiers
affect the image that is transmitted, but do not affect the image in memory. Any number of modifiers may be appended to the
IMGSHP command. For example, you can use the following command to snap and ship a bitmap image with gamma correction
and document image filtering:
IMGSNP;IMGSHP8F75K26U
IMGSHP Modifiers
A - Infinity Filter
