Note
Defect detection mechanism
After measurement region is drawn, a rectangle (defect detection region) is automatically formed in this
●
region.While moving the defect detection region around, calculate the RGB color averages at each location and
find the defect detection difference with surrounding defects. This difference is called the defect level. Calculate
the defect level for all defect detection areas. If the maximum value exceeds the judgement value, it is judged
that there are defects in the measurement region.

Specify the upper and lower limits of defect detection size based on
the size of scratch or contamination to be detected.A defect detection
region is automatically created with the number of pixels for the
defects size.
The larger the difference between upper and lower limits, the easier to
detect defects/contamination of various sizes.
