A CMOS Based Image Acquisition System for Electronic Endoscope

CMOS image sensor has many advantages compared with traditional CCD sensor; the image system based on CMOS has become a hotspot in research and development. A new image acquisition system for electronic endoscope is designed on basis of OmniVision Corporation's CMOS image sensor and camera bridge processor, in which the image data can be transferred to main processor through USB interface. The performance and configuration of the system are described in detail in this paper.
