Example
Offset Width
Set the adjustment width (in pixel units) for the detected edge position. Set a
value between -511 and 511.
The default setting is 0, which means measurement will start from position
where the edge is detected.
Left and right edges: Set the offset width on the X axis.
Upper and lower edges: Set the offset width on the Y axis.
Example: To Measure from 2 Pixel-widths Inside the Edge Detection Point
CHECK
The display cursor, which indicates the edge detection point, will also appear
at the set offset width position.
STEP 3: Registering Reference Values
Position detection can also be performed using algorithms for detecting
defects. Register the reference values when performing position detection.
The following reference values must be registered:
The X and Y coordinates of the position found as the large defect
The X and Y coordinates of the position found as the small defect
CHECK
Reference values for 2 positions can be registered, regardless of the settings
for large and small defect inspections under Measurement conditions.

Noise width (pixel)
If the density falls below the
edge level within the set range,
the detected edge is
determined to be noise.
