Abstract
A TV system for endoscopes is configured to connect to a fiber scope using an image guide fiber bundle and a rigid endoscope using a relay lens system. An image is formed by either the fiber scope or the rigid endoscope on a TV monitor. The camera control unit controls a level of the color difference signal in accordance with spatial frequency components contained in the TV signal. A variable switching unit is provided which allows the electrical circuits of the camera control unit to function selectively in accordance with the characteristics of the image transmission system.
