Final Comparison Results

Category	DEEPSOUND P5	Third-Party Equipment
Defect Inspection	Exceptional image sharpness; highly accessible and easy to inspect.	Lacks image sharpness; difficult to inspect accurately.
Defect Shape	Clear borders simplify shape and size measurement.	Blurred borders complicate precise measurement.
Program Speed	Fast response time (< 1 sec).	Sluggish response time (2-5 sec).

Conclusion: The DEEPSOUND P5’s combination of swift operation and sharp image quality significantly ensures more precise and efficient defect detection than standard alternatives.
