| Abstract: | This paper presents a medical electronic endoscopy real-time image acquisition and control system which consists of video codec chip, flash memory and FPGA. The hardware scheme and circuit design of the system is figured out, and the principle of ping-pong operation and the implementation of FPGA program is introduced. Experimental tests show that the designed system performs steadily, is easy to maintain, and reduces the cost greatly. The higher performanceprice ratio makes it have good application prospect in medical endoscoov. |
