Abstract
A plurality of electronic endoscopes, individually having insertion sections of different lengths, are classified into a plurality of endoscope groups according to the length of the insertion section. A signal cable, having a length predetermined for each endoscope group, is disposed in an electronic endoscope which belongs to its corresponding group. An identification information member, indicative of the endoscope group, is provided at a connector section of the endoscope, and identification information of the information member is identified by an endoscope control device. The control device has a function to compensate a driving pulse transmitted to the electronic endoscope and an image signal from a solid-state image sensor of the endoscope, in accordance with the identification information (cable length information).
