Real-time image capture and display system based on PCI bus for medical electronic endoscope

Abstract

This paper introduces the study and implementation of the real-time CCD image acquisition and displaying system for medical electronic endoscope. To achieve real-time video acquisition the image capturing system of endoscope is combined with computer technology in which the popular PCI local bus interface is utilized and an FPGA is used as the kernel controller. The image capturing frequency ofthe system can reach 33MHz and displaying speed can be up to 50 frames per second (fps) at 640 X 480 pixels.
