Select the gray edge value (i.e., the ratio of black and white).
(Setting range: 1 to 127; default setting: 32.) If the ratio of the
intensity of black and white is large, set to a large value, and
if the ratio of the intensity of black and white is small, set it to
a small value.
4
Select the number of times reading is repeated in the event
of incorrect reading. A fresh image will be obtained and
reading performed for the number of times specified. (Set-
ting range: 0 to 9 times; default setting: 0.)
5
Change the pixel skipping parameters used to search for a
model. (Setting range: 1 to 20; default setting: 4.)
The processing time can be reduced if the pixel skipping pa-
rameters are set to larger values. However, depending on
the image, the search may not be performed since the accu-
racy is reduced. After changing the setting, perform a
search to confirm whether the search can be performed cor-
rectly.
