Abstract
This paper presents a miniaturized CMOS camera for high-definition (HD) medical electronic endoscope system with resolution of 1.3 MegaPixel. LVDS technology is used for image data stream transmission between the sensor and the HD image workstation to realize a long distance, high speed, high signal integrity and low noise system. Considering the real-time video image processing and the complexity of the design of HD image workstation, four solutions for medical electronic endoscope systems, namely USB based image acquisition system, PCIe acquisition data board based method, ARM embedded system based solution and DSP based electronic endoscope system have been proposed, analyzed and compared with each other. We found that the four solutions have their own advantages and disadvantages. Taking into account the strong control capacity of ARM, powerful data processing ability and high operating speed of DSP, good portability and other factors, we decided to use ARM + DSP embedded based system.
