Adjusting Blister Windows
6–4
When Flipped Objects is set to Yes , and the object type is “ 1–color ,” the
system will accept any learned color appearing within a pocket. Thus, when
tablets like the one shown Figure 6.4 are to be inspected, setting
Flipped
Objects to Yes will enable them to pass inspection (so long as the system
has learned both colors) regardless of which color faces the camera.

Auto Locate
The auto locate function can evaluate the position of a pocket’s contents
relative to the contents of other pockets.
The auto locate function enables the system to recognize a blister even if the
blister is shifted from its expected position within an inspection window.
Auto locate also helps accommodate variations resulting from minor
triggering inconsistencies or web registration.
When you pick the Auto Locate menu item, it toggles to the alternate state.
Thus, if it currently displays Auto Locate: Enabled , it toggles to Auto
Locate: Disabled (and vice versa).
NOTE: When the auto locate function enabled, the system may not be able
to locate blisters that have missing tablets. While the system will reject such
blisters, it may report a “
Position ” error instead of a “ Missing ” error.
Define Background
The background inspection function enables the system to inspect the area
between the pockets of a blister for foreign matter. When the background
function is enabled, the system can identify “holes” formed by areas where
the expected background color is absent. (During the auto setup process, the
background color is learned as
Color 1 .)
Normally, holes in the taught background color represent pockets. Their area
should not exceed the area of the tablets or capsules plus the amount of
“extra area” that is currently in effect (See the Extra Area % section on page
6–6 for details). In addition, the position of those holes must fall within a
known range. With the background function enabled, a hole in the
background color that is in the wrong place, or is of an unacceptable size,
will result in a failed inspection, and will produce a “
Foreign ” error
condition.
