Chapter 8 - Imaging Commands
Imaging Commands with their modifiers send imaging commands to the imager on a single-use
basis, and take effect for the next subsequent image capture. Once that capture is complete, the
imager reverts to its imaging default settings. If you wish to change a default setting, you must
use the serial default command (see Imaging Default Commands on page 127). When the serial
default command is used, that selection becomes the new default setting for the imager.
Image Snap - IMGSNP
An image is taken whenever a trigger command is sent, or when the Image Snap (IMGSNP)
command is processed. Image Snap is the command processor for image capture, or taking a
picture.
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:
Sets the Image Snap style.
0P
Decoding Style
. This is similar to the current format for decoding, however,
this processing allows a few frames to be taken until the exposure parameters are met.
Then the last frame is available for further use.
1P
Photo Style (default)
. This attempts to mimic a simple digital camera, and
results in a visually optimized image.
2P
Manual Style
. This is an advanced style, and should not normally be used. It
allows you the most freedom to set up the imager, 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, notifying the user that the imager
can be moved.
E - Exposure:
This allows you to set the exposure time. Units are 127 microseconds. For
example, an exposure setting of 50 x .000127ms = 6.35ms exposure time. Exposure is used in
Manual Style only. (Default = 7874)
nE
Range: 0 - 7874
Example of Exposure at 7874E with
fluorescent lighting:
Example of Exposure at 100E with
fluorescent lighting:
G - Gain:
This modifier boosts the signal and multiplies the pixel value. The range is 1-8.
