Extending DOF with Automatic Image Settings Selection
(Cycle
All In Same Phase) for Liquid Lens Models
For Liquid Lens models, multiple Image Acquisition Settings can be configured
and enabled internally through the application software to extend the reader's
depth of field. During each reading phase, decoding will be attempted by
applying each enabled Image Acquisition Setting (cyclically).
Example:
Read a 15 mil Data Matrix ECC 200 code covering a range from 140 to 320 mm.
The reading distance range is too long to be covered by a single acquisition
setting, so two acquisition settings could be used in which the first has a
Reading Distance of 195 mm
and the second has a
Reading Distance of 300 mm
.
When both are enabled, the reader cycles through the two settings effectively
producing the extended DOF.
NOTE
Since many factors and parameters contribute to maximizing the reading
process, it is suggested to use the DL.CODE Image Auto-Setup and Focus
Autolearn tools to set the different acquisitions settings.
NOTE
Multi Image Acquisition Settings Procedure using Automatic Image Settings
Selection:
1. Using the DL.CODE Image Auto-Setup and Focus Autolearn tools, set the
first acquisition setting (default) for the 195 mm Reading Distance. Then
Save on Device.
2. Add another Image Setting, and using the DL.CODE Image Auto-Setup and
Focus Autolearn tools, set the second acquisition setting for the 300 mm
Reading Distance. Then Save on Device.
3. On the Reading Phase step > General Settings > Acquisition Settings, set
the Image Settings Selection to Automatic (default). Then Save on Device.
4. Verify that the reader decodes at both distances with the DL.CODE Monitor.
Cycling through Image Acquisition Settings that require changing the Reading Dis-
tance parameter (for liquid lens models), drastically reduces the frame rate due to the
liquid lens refocusing delay as well as by the number of settings simultaneously
enabled. Therefore this may not be the best solution for high speed applications. For
high speed applications it is best to use the External Image Settings Selection (Input
Select) feature described on page 146. Otherwise use multiple readers set to different
reading distances.
By default the Image Settings Selection parameter is set to Automatic.
