2.
Select whether Right & Left Reverse of Data Matrix codes is nec-
essary.
3.
Select the code size.
(10
10 to 26
26; Default setting: 10
10)
4.
Change the pixel skipping parameters used to search for a model.
(1 to 20, default setting: 5)
The processing time can be reduced if the pixel skipping param-
eters are set to larger values. However, depending on the image,
the search may not be performed since the accuracy is reduced.
After changing the setting, perform a search to confirm whether
the search can be performed correctly.
5.
Set the correlation threshold value for detecting finder patterns.
Locations with correlation values higher than the threshold are
detected. (1 to 100; Default setting: 50)
6.
Set the timeout time for decode processing for reading one im-
age. (20 to 2,000 ms; Default setting: 500 ms)
Note
If Display Settings/Finder Pattern is set to ON, whether finder
patterns can be detected or not can be confirmed on the screen.
If detection is not possible, decrease the correlation threshold
value and the pixel skipping parameter and check the model
image.
If, on the other hand, too many places are detected, increase the
correlation value and pixel skipping parameter.
ON
For reading an image after reflection, or through the
back of a transparent material, such as glass.
OFF
(Default set-
ting)
For normal reading (from the front of the object)
Pixel Skipping X
Pixel Skipping Y
Set the number of pixels
skipped when searching.
