Imaging Commands
The document reader is like a digital camera in the way it captures, manipulates, and transfers images.
The following commands allow you to alter the way the document reader performs these functions.
Single-Use Basis
Imaging Commands with their modifiers send instructions to the document reader on a single-use basis,
and take effect for a single image capture. Once that capture is complete, the document reader reverts
to its imaging default settings. If you want to permanently change a setting, you must use the serial
default commands (see Chapter 2). When the serial default command is used, that selection becomes
the new, permanent setting for the document reader.
Command Syntax
Multiple modifiers and commands can be issued within one sequence. If additional modifiers are to be
applied to the same command, just add the modifiers to that command. For example, to add 2 modifiers
to the Image Snap command, such as setting the Imaging Style to 1P and the Wait for Trigger to 1T, you
would enter IMGSNP1P1T.
Note: After processing an image capture command (IMGSNP or IMGBOX), you must follow it with an
IMGSHP or IMGACP command if you want to see it on your terminal.
To add a command to a sequence, each new command is separated with a semicolon. For example, to
add the Image Ship command to the above sequence, you would enter IMGSNP1P1T;IMGSHP.
The imaging commands are:
Image Snap - IMGSNP (page 1-1)
Image Ship - IMGSHP (page 1-5)
Intelligent Signature Capture - IMGBOX (page 1-15)
The modifiers for each of these commands follow the command description.
Step 1 - Take a Picture Using IMGSNP
Image Snap - IMGSNP
An image is taken whenever the hardware button is pressed, or when the Image Snap (IMGSNP) com-
mand is processed.
The image snap command has many different modifiers that can be used to change the look of the
image in memory. Modifiers always begin with numbers and end with a letter (case insensitive). Any
number of modifiers may be appended to the IMGSNP command. For example, you can use the follow-
ing command to snap an image, increase the gain, and have the beeper sound once the snap is com-
plete:
IMGSNP2G1B

1 - 2
IMGSNP Modifiers
P - Imaging Style
This sets the Image Snap style.
0P Decoding Style. This processing allows a few frames to be taken until the exposure
parameters are met. The last frame is then available for further use.
1P Photo Style
(default). This mimics a simple digital camera, and results in a visually
optimized image.
2P Manual Style. This is an advanced style that should only be used by an experienced user.
It allows you the most freedom to set up the document reader, and has no auto-exposure.
B - Beeper
Causes a beep to sound after an image is snapped.
0B No beep
(default)
1B Sounds a beep when the image is captured.
T - Wait for Trigger
Waits for a hardware button push before taking the image. This is only available when using Photo
Style (1P).
0T Takes image immediately
(default)
1T Waits for a button push, then takes the image
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 document reader is in a stand.
LED illumination (1L) is preferred when the document reader is hand held. LED State is not available
when using Decoding Style (0P).
0L LEDs off
(default)
1L LEDs on

1 - 3
A - Aimer Lines
Sets whether the aimer lines will be captured with the image or not. In order to capture the aimer lines,
the LEDs must also be off. If the LEDs are on, the aimer lines will not be captured.
0A Aimer Lines off
(default)
1A Aimer Lines on
E - Exposure
Exposure is used in Manual Style only (2P), and allows you to set the exposure time. This is similar
to setting a shutter speed on a camera. The exposure time determines how long the imager takes to
record an image. On a bright day, exposure times can be very short because plenty of light is
available to help record an image. At nighttime, exposure time can increase dramatically due to the
near absence of light. Units are 127 microseconds.
(Default = 7874)
n
E Range: 1 - 7874
Example of Aimer Lines Off (0A): Example of Aimer Lines On (1A) with LEDs
off (0L):
Example of Exposure at 7874E with
fluorescent lighting:
Example of Exposure at 100E with
fluorescent lighting:

1 - 4
G - Gain
Gain is used in Manual Style only (2P). Like a volume control, the gain modifier boosts the signal and
multiplies the pixel value. As you increase the gain, the noise in an image is also amplified.
1G No gain
(default)
2G Medium gain
4G Heavy gain
8G Maximum gain
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 (1P).
(Default = 125)
n
W 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)
n
D Range: 0 - 255
U - Update Tries
This sets the maximum number of frames the document reader should take to reach the D - Delta for
Acceptance. Update Tries is only available when using Photo Style (1P).
(Default = 6)
n
U Range: 0 - 10
Example of Gain at 1G: Example of Gain at 4G: Example of Gain at 8G:
Example of White Value at 75W: Example of White Value at 125W: Example of White Value at 200W:

1 - 5
% - 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 = 97)
n% Range: 1 - 99
Step 2 - Ship a Picture Using IMGSHP or IMGACP
Image Ship - IMGSHP
An image is taken whenever the button is pressed, or when the Image Snap (IMGSNP) command is pro-
cessed. The last image is always stored in memory. You can “ship” the image by using the IMGSHP or
IMGACP command.
The image ship and image auto crop commands have many different modifiers that can be used to
change the look of the image output by the document reader. Modifiers affect the image that is transmit-
ted, but do not affect the image in memory. Modifiers always begin with a number and end with a letter
(case insensitive). Any number of modifiers may be appended to the IMGSHP or IMGACP command.
For example, you can use the following command to snap and ship a bitmap image with gamma correc-
tion and document image filtering:
IMGSNP;IMGSHP8F75K26U
Image Auto Crop - IMGACP
Image Auto Crop removes unwanted portions of an image, such as blank space surrounding an image.
Image Auto Crop uses artificial intelligence to search for the area of the image that contains text. It then
crops the image to just that area and adjusts it to a horizontal display. Depending on the size and posi-
tion of the document, this may possibly result in an upside-down or sideways image. The image can
then be rotated to the proper orientation using your local software. Smaller documents will crop more
quickly than larger documents. The accuracy of auto crop is affected by the density of the text, amount
of non-text features, and contrast in the image.
Note: Any modifiers to IMGACP are applied to the resultant, auto cropped image.
The same modifiers are used for image ship and image auto crop. The following command was used to
take and crop an image that had the white value lowered and the edge sharpen filter on:

A - Infinity Filter
Enhances pictures taken from very long distances (greater than 10 feet or 3m). The Infinity Filter
should not be used with Image Auto Crop - IMGACP (page 1-5).
0A Infinity filter off
(default)
1A Infinity filter on

C - Compensation
Flattens the image to account for variations in illumination across the image.
0C Compensation disabled
(default)
1C Compensation enabled
D - Pixel Depth
Indicates the number of bits per pixel in the transmitted image (KIM or BMP format only).
8D 8 bits per pixel, grayscale image
(default)
1D 1 bit per pixel, black and white image
E - Edge Sharpen
An edge sharpen filter cleans up the edges of an image, making it look cleaner and sharper. While
edge sharpening does make the image look cleaner, it also removes some fine detail from the original
image. The strength of the edge sharpen filter can be entered from 1 to 24. Entering a 23E gives the
sharpest edges, but also increases noise in the image.
0E Don’t sharpen image
(default)
14E Apply edge sharpen for typical image
n e Apply edge sharpen using strength n ( n = 1-24)
Example of Compensation at 0C: Example of Compensation at 1C:
Example of Edge Sharpen at 0E: Example of Edge Sharpen at 24E:

F - File Format
Indicates the desired format for the image.
0F KIM format
1F TIFF binary
2F TIFF binary group 4, compressed
3F TIFF grayscale
4F Uncompressed binary (upper left to lower right, 1 pixel/bit, 0 padded end of line)
5F Uncompressed grayscale (upper left to lower right, bitmap format)
6F JPEG image
(default)
8F BMP format (lower right to upper left, uncompressed)
H - Histogram Stretch
Increases the contrast of the transmitted image. Not available with some image formats.
0H No stretch
(default)
1H Histogram stretch
Example of Histogram Stretch at 0H: Example of Histogram Stretch at 1H:

1 - 9
I - Invert Image
Invert image is used to rotate the image around the X or Y axis.
Note: This feature should only be used with Image Ship - IMGSHP (page 1-5). Using this feature with
Image Auto Crop - IMGACP (page 1-5) may produce undesired results since Image Auto Crop
attempts to rotate an image to a horizontal display.
1ix Invert around the X axis (flips picture upside down)
1iy Invert around the Y axis (flips picture left to right)
IF- Noise Reduction
Used to reduce the salt and pepper noise in an image.
0if No salt and pepper noise reduction (default)
1if Salt and pepper noise reduction

IR - Image Rotate
Note: This feature should only be used with Image Ship - IMGSHP (page 1-5). Using this feature with
Image Auto Crop - IMGACP (page 1-5) may produce undesired results since Image Auto Crop
attempts to rotate an image to a horizontal display.
0ir Image as snapped (rightside up) (default)
1ir Rotate image 90 degrees to the right
2ir Rotate image 180 degrees (upside down)
3ir Rotate image 90 degrees to the left
IU - Image Adaptive Text Filter
The Adaptive Text Filter automatically sharpens the edges and smooths the area between the edges
of text in an image. The Adaptive Text Filter enhances images of documents such as ID cards and
prescriptions, resulting in crisper text.
See U - Document Image Filter (page 1-13) for information about setting the Document Image Filter
manually.
Note: The Adaptive Text Filter should not be used concurrently with the IS - Unsharp/Brighten Filter.
0iu Adaptive Text Filter off (default)
1iu Adaptive Text Filter on
Example of Image Rotate set to 0ir: Example of Image Rotate set to 2ir:
Example of Image Rotate set to 1ir: Example of Image Rotate set to 3ir:
Example of Adaptive Text Filter On (1iu):Example of Adaptive Text Filter Off (0iu):

1 - 11
IS - Unsharp/Brighten Filter
The Unsharp/Brighten Filter automatically sharpens the text and brightens the contrast of the image,
making text more readable. This is similar to the Image Adaptive Text Filter, however it brightens the
image as well. You should test both image processing techniques to determine which filter works best
for your environment.
Note: The Unsharp/Brighten Filter should not be used concurrently with the IU - Image Adaptive Text
Filter.
0is Unsharp/Brighten Filter off (default)
1is Unsharp/Brighten Filter on
J - JPEG Image Quality
Sets the desired quality when the JPEG image format is selected. Higher numbers result in higher
quality, but larger files. Smaller numbers result in greater amounts of lossy compression, faster
transmission times, lower quality, but smaller files.
(Default = 50)
n
J Image is compressed as much as possible while preserving quality factor of n ( n = 0 - 100)
0J worst quality (smallest file)
100J best quality (largest file)
K - Gamma Correction
Gamma measures the brightness of midtone values produced by the image. You can brighten or
darken an image using gamma correction. A higher gamma correction yields an overall brighter
image. The lower the setting, the darker the image. The optimal setting for text images is 50K.
0K Gamma correction off
(default)
50K Apply gamma correction for brightening typical document image
n K Apply gamma correction factor n ( n = 0-1,000)

L, R, T, B, M - Image Cropping
Note:Image Cropping should not be used with Image Auto Crop - IMGACP (see page 1-5).
Ships a window of the image by specifying the left, right, top, and bottom pixel coordinates. Device
columns are numbered 0 through 1279, and device rows are numbered 0 through 959.
n L The left edge of the shipped image corresponds to column n of the image in memory. Range:
000 - 1279. (Default = 0)
n
R The right edge of the shipped image corresponds to column n - 1 of the image in memory.
Range: 000 - 1279. (Default = all columns)
n
T The top edge of the shipped image corresponds to row n of the image in memory. Range:
000 - 959. (Default = 0)
n
B The bottom edge of the shipped image corresponds to row n - 1 of the image in memory.
Range: 000 - 959.
(Default = all rows)
Alternately, specify the number of pixels to cut from the outside margin of the image; thus only the
center pixels are transmitted.
n M Margin: cut n columns from the left, n + 1 columns from the right, n rows from the top, and
n + 1 rows from the bottom of the image. Ship the remaining center pixels. Range: 0 - 478.
(Default = 0, or full image)
P - Protocol
Used for shipping an image. Protocol covers two features of the image data being sent to the host.
It addresses the protocol used to send the data (Hmodem, which is an Xmodem 1K variant that has
additional header information), and the format of the image data that is sent.
0P None (raw data)
2P None
(default for USB)
3P Hmodem compressed (default for RS-232)
4P Hmodem
