Abstract
An endoscope of the type having in its imaging system a solid state imaging device provided in its insertable section into a cavity of a living body for receiving an optical image and converting it into electrical signals which are processed and then transmitted to a monitor to be visualized thereon. The endoscope comprises an operating part having an insertable section into a cavity which includes therein a solid state imaging device for receiving an optical image and converting it into electrical signals, a control unit for providing driving signals for the solid state imaging device and processing the signals from the solid state imaging device to provide a video signal and a display for receiving the video signal from the control unit to be visualized as, for example, a television picture. The operating part further includes an adjusting means for modifying levels of the driving signals corresponding to the characteristics of the solid state imaging device. The provision of the adjusting means in the operating part permits a control unit to be commonly applied to endoscopes having different characteristics of solid state imaging devices.
