Gain/Exposure Priority for Snapshot Mode

Parameter # 562
This parameter alters the digital scanner's gain exposure priority when it acquires an image in Snapshot Mode
in auto exposure mode.
•
Scan Low Exposure Priority to set a mode in which the digital scanner favors higher gain over
exposure to capture an image. This results in an image that is less susceptible to motion blur at the
expense of noise artifacts. However, for most applications, the amount of noise is acceptable.
•
Scan Low Gain Priority to set a mode in which the digital scanner favors longer exposure time rather
than higher gain to capture an image. This ensures that the image is less noisy and produces fewer
artifacts during post processing activities like image enhancement (sharpening). The mode is
recommended for fixed mount / fixed object image capture since the image acquired is susceptible to
motion blur.
•
Scan Autodetect (default) to set a mode in which the digital scanner automatically selects Gain Priority
or Low Exposure Priority mode for Snapshot Mode. If the digital scanner is in a magnetic read switch
enabled stand (or it is configured in Blink Mode), it uses Low Gain Priority mode. Otherwise, it uses the
Low Exposure Priority mode.
