Design of Medical Electronic Endoscope Imaging System

摘要

Medical Electronic Endoscope (MEE) is a widely used medical instrument. Using the Field Programmable Gate Array (FPGA), we accomplish three parts of work: 1) Optical imaging system. 2) Driving of the Charged Coupled Device (CCD), the function of image data acquisition and display. 3) Based on the dot-array plate arithmetic, a real-time correction system of image distortion via hardware is designed. 4) On the basis of video-servo control method, the system achieves automatic brightness control of electronic endoscope. Finally, a medical electronic endoscope system with a real-time correction system of high-resolution color image distortion is developed.
