ABSTRACT:
The electronic endoscope apparatus having an isolation circuit of the present invention is provided with an endoscope provided with an imaging device converting the photoinformation of an object to an electric signal and a video signal processing device processing the output signal of the imaging device to be a video signal. An isolation circuit separates and isolates the circuit forming the video signal processing device into a patient circuit including the imaging device and a secondary circuit which is a circuit not included in the patient circuit. A signal producing circuit makes either one of the patient circuit and secondary circuit a transmitted side circuit and produces a signal required by the transmitted side circuit on the basis of a signal forming a video transmitted to the transmitted side circuit through the isolation circuit from the transmitting side circuit.
