Setting Position Displacement Compensation Regions
The following four figures can be chosen for position displacement compensa-
tion regions, depending on the figure of the positioning mark.

Circles
STEP 1: Setting Measurement Conditions
Set the conditions to search for the positioning mark.
The asterisk (*) indicates the default setting.

Circular
Circle
Searches for a circle of a specified size and outputs the
position coordinates (center of the circle).
Box
Box
Searches for a rectangle of a specified size and outputs
position coordinates. The center or one of the four corners
can be selected for the position coordinates.
Other figures
One angle used as a
mark
Cross
point
Outputs the position coordinates of the intersection of two
lines. If there are multiple lines, the following conditions can
be set:
• Output the cross point only for an intersection at a certain
angle.
• Output the cross point only for an intersection of lines of a
certain length.
Several angles are
used to one set of
coordinates
Multiple
cross
points
Up to 20 cross point coordinates can be found.
The detection conditions can be changed to suit any pur-
pose.

Select whether the color of the circle that is the positioning
mark will be white or black compared to the background.
Select “white/black” if the circle color is not fixed to either
black or white. (Black*, white, white/black)
Select whether pixel skipping (1 pixel) will be used when
searching for the circle. (ON*, OFF)
Processing is faster if pixel skipping is turned ON, so
normally “ON” is appropriate. However, if the
measurement values are inconsistent, set to “OFF.”
Checks circle deformation. (0% to 100% (0%*))
The value drops if the circle is deformed or chipped. The object is not
extracted as a circle if the value is lower than the set value.
