Image Capture
Figure 29. Aiming Beam Positioning
Linear bar codes
2D Matrix symbol
The aiming beam is smaller when the imager is closer to the code and larger
when it is farther away. Symbologies with smaller bars or elements (mil size)
should be read closer to the unit. Symbologies with larger bars or elements
(mil size) should be read farther from the unit. To scan a label, hold the imager
at an appropriate distance from the target, pull the trigger, and center the aiming beam on the symbol.
Scanning Illumination
Another feature that can be enabled for 2D scanning is an array of illumination LEDs. These LEDs provide illumination in dark environments and can
improve scanning performance under certain lighting conditions. By default,
the illumination LEDs are turned on. Illumination LEDs can be disabled
using the PDT parameters. See the PRG for complete information on programming the LEDs.
Image Capture
The 2D Imager can be used for capturing, manipulating, and transferring
images.
You can set options for image capture in the Imaging Control Panel. Various
image formats can be selected, including TIFF, JPEG and BMP. You can also
scale, rotate, and modify image quality settings. See the PRG for detailed information on using the Falcon 2D for image capture.
