title: Electronic endoscopy in perspective.
abstract: Electronic endoscopy, developed in 1983, enables the endoscopic image to be transmitted through electric signals that can be easily processed by computer. An electronic endoscope is composed of three vital parts, i.e., a charge-coupled device (CCD) that converts the image to electric signals, a video processor that converts analog electric signals to the digital and processes them to become video signals, and a television monitor. The introduction of electronic endoscopy has enabled computer management of endoscopic images, on one hand, and provided an opportunity for image processing and analysis, on the other. A digital image management system will further develop into a database of endoscopic images. Combined with the technologies of remote control and remote sensing, the introduction of CCD to endoscopy has made it possible to transform the endoscope, so that it could become a capsule. Future advances in the research of image processing and analysis will lead to the development of a system of automated endoscopic diagnosis.
