Calibration Options
Exposure
Note:
If you choose to calibrate the reader by sending a
<@CAL>
command, a decode
is also required for the calibration process to be completed successfully.
Note:
This table shows guidelines for exposure settings based on various line speeds.
The settings shown depend on the reader’s optical configuration and on symbol element size.
Disabled
When disabled, exposure is fixed and is not part of the calibration process.
Enabled
When enabled, exposure is calibrated to provide the best image quality and performance
for the symbol present in the field of view. Calibration requires that a decodable symbol be
placed in the field of view, as feedback from the symbol decoding process is used to select
the best exposure setting. If a symbol is not decoded the process will result in a fail condition.
Exposure is enabled by default.
Quick Calibrate
Quick Calibrate
uses the automatic exposure control feature of the image sensor to
adjust the exposure value such that the current image falls into a desirable region of the
image sensor’s sensitivity range, ensuring optimal image luminance. The image sensor
converges on the optimal exposure value within a few image frames.
Definition:
Unless the application is static, exposure should be configured based on
the application’s line speed. The table below is a general guideline for
exposure configurations at various line speeds.
