At present, video endoscopic systems (VE) are available from four companies. We have had an opportunity to test these instruments in clinical practice. In principle, all the VE's are similar in that they employ charge coupling devices (CCD-chips) as image sensors, but they differ significantly in CCD chip technology and in the color acquisition technique. The basic aspects of CCD chip and transmission technology of relevance to the endoscopist are discussed. The mechanical properties of the endoscopes are listed. Finally, we provide an outlook on the determinants of the optical performance of VE's. The optical performance of a VE can be characterized by its resolution and color performance.
目前，有四家公司提供视频内镜系统（VE）。我们有机会在临床实践中对这些仪器进行测试。原则上，所有的视频内镜系统都很相似，因为它们都采用电荷耦合器件（CCD芯片）作为图像传感器，但它们在CCD芯片技术和颜色采集技术方面有很大差异。文中讨论了与内镜医师相关的CCD芯片和传输技术的基本方面。列出了内镜的机械性能。最后，我们对视频内镜系统光学性能的决定因素进行了展望。视频内镜系统的光学性能可以通过其分辨率和颜色性能来表征。
