Paper Abstract

A video laparo endoscopic system was introduced in this paper, which included a camera, a white LED illuminator and a high-definition image processing workstation. The camera adopted a CMOS image sensor to achieve high resolution imaging. Four LEDs were assembled directly to the front-end of the endoscope. Optical fiber coupling system was unnecessary. Image processing workstation was used to demosaic, enhance, and display the image on an LCD monitor in real time, and then capture and store the image. The image resolution reached 1280*1024. This system can be used directly in a laparoscope casing of 10mm in diameter. It is compact, low-cost, high-definition, and suitable for the single-port laparoscope surgery.
