removal" area.
Density change
• Absolute

measur
ement
method is
"Derivation")

Select whe
ther a black-to-white change or a white-to-black change should
be recog
nized as a density change in the specified region.
Edge No.
0 to 99
[0]
Specify the edge number used to extract edges.
Edge numbers are assigned to detected edges starting from 0 and going
on in the di
re
ction from the start point (the arrow point) to the end point
(the direction of arrow) in the selected area.

[50] to [100]
• Value of density
0 to 255
[20] to [255]
Select the density change level to be detected as edges.
The upper limit of edges can be set only when the measurement method
is "Derivatio
n".

Description
Noise level
0 to 442
[5]
When detection is affected by noise, increase this value.
Reference: "Appendixes Measurement Mechanism Noise Level" in the
"V
isi
on System FH/FZ5 Series User's Manual (Z365)"
Noise width
0 to 9999
[0]
Set the width for judging noise.
When detection is affected by noise, increase this value.

th
e "V
ision System FH/FZ5 Series User's Manual (Z365)"
Filter strength
0 to 100
[0]
If a valley appears in the histogram ar
ound the edge threshold value due
to noises, smoothen the edge profile using a filter to prevent wrong error
detection from being detected.
Strengthening the filter smoothen the edge profile further.
