Problems with Conventional Methods
Even after multiple attempts, users cannot achieve the ideal settings.
Conventional vision systems involve a cycle of adjustments—tightening criteria when defects are not detected,and relaxing them if yield rate worsens—meaning users never end up finding the best settings.
Defect Oversights
Scratches that should be judged as NG are not detected and are judged as OK in error.
Adjustments
False Positives Occur
Yield rate worsens as contamination that should be judged as OK is judged as NG in error.
