Abstract

Objective: This study aims to explore the potential of full-range autofocus (FAF) technology to improve image clarity and operational ease in endoscopic procedures.
Methods: The paper analyzes the application and development of manual focus, autofocus, manual zoom, and auto zoom technologies in clinical endoscopy. The clinical value of FAF technology in endoscopy, including intelligent scene linkage and continuous optical lossless zoom, is discussed.
Results: The application of FAF technology significantly enhances medical diagnosis and treatment by providing clearer and more flexible imaging. This technology allows for seamless focusing from near to far distances, improving the accuracy and effectiveness of medical procedures.
Conclusions: The FAF technology represents a significant advancement in endoscopic technology. It not only improves diagnostic precision and treatment efficiency but also contributes to safer and more comfortable medical services, which can promote further development in the medical industry.
