The method of registering model images of finder patterns, and using
these models to find finder patterns from input images is called “pat-
tern search.” Because image patterns are used, code positions can
still be found with greater accuracy than with Normal mode, even if
the printing quality is poor.
Note
1. A code can be registered as the model with a direction of 0
•
, 90
•
,
180
•
, 270
•
, or 4 directions (0
•
, 90
•
, 180
•
, or 270
•
). Codes can be
read as long as they are within
–
10
•
of the registered model. The
“4 directions” setting results in a longer processing time than the
other settings.
2. When using this menu, set the field of vision to satisfy the follow-
ing conditions.
• There are more than 10 pixels per cell.
• There is a margin of at least 2 cells around the code.
