Mask Setting (Defect)
Mask the measurement region when measuring it.
There are two types of masks, namely, a static mask that sets the mask region independent of measurement
and a dyna
mic mask that uses images generated in another unit for each measurement.
Creating a static mask
A static mask can be created manually or from an image of another unit.
1 In the Mask setting area, select "Static
mask".
Generating a mask manually
1 In the Static mask set area, select
"Region extract".
2 Select the selection region type OR or
NOT and drag an image directly.
A region is created along successive similar
colors from the selected place. It is not
masked if the selection region type is OR.
It is masked if the selectio
n
region type is
NOT.
To deselect a selected region, click [Undo].
To edit a region selected with OR/NOT, click
[Sele
c
ted region edit].

mask setting area.
A mask cannot be made with only one region specified using Wide line, Wide circle, or Arc, as the figure.
