Description
Area measurement
• Checked
• [Unchecked]
Place a check when you want to measure the size of defects. This
item ca
n divide the high defect detection regions into groups and
output the surface and center of gravity coordinates of the group with
the largest area.
However, when only one region is specified with "Wide line", "Wide
circle"
,
or "Arc", area measurement is not possible.
Area defect level
0 to 999
[20]
If you place a heck at Area Measurement, set defect level counted in
the defect area.
Detect color
(for monochrome
cameras only)
Black only
Select this value to detect defect
s
that look darker than the
background.
White only
Select this value to detect defect
s that look lighter than the

[Both white & black] Select this value when the brightness of defects is not known.
Region inspection mode
The comparison direction depends on the
measuremen
t region shapes and number.
For a rectangle, ellipse or polygon, comparison is
with the
defect detection
regions above, below, left
and right. This is called region inspection mode.
For a wide line, wide arc or wide circle,
comp
arison
is only with the two neighboring defect
detection regions.
However, even for a wide line, wide arc or wide
circle,
w
hen two or more figures are drawn,
measurement is in region inspection mode.
