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 1-14)

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) command 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 following command to snap an image, increase the gain, and have the beeper sound once the snap is complete:

IMGSNP2G1B

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 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.

(default)

. This mimics a simple digital camera, and results in a visually optimized image.

Document Reader Imaging Guide 1 - 1

T - Wait for Trigger

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:

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

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)

nE Range: 1 - 7874

G - Gain

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:

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)

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 document reader 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

Document Reader Imaging Guide 1 - 3

% - Target Set Point Percentage

Example of Target Set Point Percentage at 97%:

Example of Target Set Point Percentage at 40%:

Example of Target Set Point Percentage at 50%:

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
