| Abstract: | This design had been based on complex programmable logic device （CPLD）and dedicated video processing chip for high-resolution fast auto-focus video booth. The microscope auto-focus algorithms used in teaching video booth, with simple, high precision, fast focusing, etc. The use of the characteristics of CPLD programming flexibility to design systems, sped up data processing speed, saved on the hardware costs. Experiments indicate that the system focuses on speed, precision and effectiveness of the picture is good. |
