The settings will be registered and the screen in (4.) will return.
The measurement region and the positions where defects were located will
be displayed. The defects will be indicated by a display cursor.
STEP 2: Re-registering Reference Values
Position detection can also be performed using algorithms for detecting
defects. When a measurement region is drawn, measurement is performed for
the displayed image and the results are registered as the reference values (X
and Y coordinates of the position where the defect was found). If this function
is used, however, the reference value alone can be re-registered based on the
currently displayed image.
Example: Inspecting Whether or Not the Measurement Object Is Always
in the Same Position
Display a measurement object in the correct position, detect a mark, and reg-
ister that position as the reference position.

The reference value can be changed to enable the following function.
Inspecting Positions from a Specified Point
Once a mark has been detected in the image currently displayed, the refer-
ence position is changed to an suitable point. Position inspection can be per-
