Exposure ROI with verification according to ISO/IEC 29158
When using a verification reference with ISO/IEC 29158, the exposure ROI must be set in
such a way that the code to be verified is approximately in the center of the ROI. In addition
to this, the code to be verified needs to be fully inside the exposure ROI during the image
acquisition. For the following reasons, it is advisable to keep the exposure ROI as small as
possible, while taking into consideration the flexibility required for the application:
● Optimizing the speed:
The smaller the exposure ROI, the faster the exposure control will work.
● Disruptions in the image:
If the acquired images contain disturbances similar to code, the exposure control can fail
completely because the time available for the exposure control is limited. In this case, the
mean light value required in the standard might not be reached. The same applies to
codes that are difficult to read.
● Multiple codes in the image:
If there are or can be several codes in the image field, the exposure ROI needs to be set
up in such a way that it only contains the code to be verified. If there are several codes to
be verified, the exposure ROI should only include the code closest to the center. The

Description
The reference decoding according to
ISO/IEC 16022:2006 signals an error when searching
for the finder pattern (only for verification according to
ISO/IEC 15415 or ISO/IEC 29158).
The reference decoding according to
ISO/IEC 16022:2006 signals an error when determin-
ing the error correction (only for verification according
to ISO/IEC 15415 or ISO/IEC 29158).
The maximum supported code size for verification
according to ISO/IEC 15415 or ISO/IEC 29158 is
104x104 cells.
During verification, a cell size was measured that is
less than the minimum X-dimension setting (only for
verification according to ISO/IEC 29158).
During verification, a cell size was measured that is
greater than the maximum X-dimension setting (only
for verification according to ISO/IEC 29158).
Step #n could not be executed due to a lack of re-
sources (memory).
