Imager Preferences
The parameters in this chapter control image capture characteristics. Image capture occurs in all modes of
operation, including decode, video, and snapshot.
Operational Modes
The imager has three modes of operation:
•
Decode Mode
•
Snapshot Mode
•
Snapshot with Viewfinder Mode
•
Video Mode.
Decode Mode
By default, upon a trigger event, the imager attempts to locate and decode enabled bar codes within its field of
view. The imager remains in this mode as long as the trigger is active or until it decodes a bar code.
Snapshot Mode
Use Snapshot Mode to capture a high-quality image and transmit it to the host. To temporarily enter this mode
capture the
Snapshot Mode
bar code. The imager blinks the green LED at 1-second intervals to indicate it is not in
standard operating (decode) mode.
In Snapshot Mode, the imager turns on the laser aiming pattern to highlight the area to capture in the image. The
next trigger event instructs the imager to capture a high quality image and transmit it to the host. A short time may
pass (less than 2 seconds) between when you activate the trigger and image capture as the imager adjusts to the
lighting conditions. Hold the imager steady until a successful image capture, denoted by a single beep.
If you do not activate a trigger event within the Snapshot Mode Timeout period, the imager returns to Decode
Mode. Use
Snapshot Mode Timeout on page 7-13
to adjust this timeout period. The default timeout period is 30
seconds.
To disable the laser aiming pattern during Snapshot Mode, see
Snapshot Aiming Pattern on page 7-14
Use
Video View Finder on page 7-24
to enable
Snapshot with Viewfinder Mode
. In this mode the imager
behaves as a video camera until the trigger is active, at which time a Snapshot occurs as described above.
