An endoscopehas a CCDincorporated in the distal part of an insertion unitthereof. The sensitivity of the CCDcan be varied by applying a plurality of pulsating driving signals so as to change an electron multiplication rate. The endoscopeis connected to a processorso that it can be disconnected freely. Information representing a type of endoscope stored in advance in a ROMis transmitted to a controllerincorporated in the processor. The control meansuses a CCD sensitivity control meansto control the sensitivity of the CCDaccording to the type of connected endoscope. Consequently, a view image of proper brightness can be produced irrespective of the type of endoscope
