Electronic endoscope apparatus
First Claim
1. An electronic endoscope apparatus comprising:
- a processor unit; and
an electronic endoscope selected from various types of electronic endoscopes having different pixel numbers of a solid-state pickup element which pick up an object, each of the various types of electronic endoscopes being capable of interchangeably connecting to the processor unit, so as to generate digital picture signals,wherein the processor unit comprises a differential signal outputting portion that generates digital picture signals corresponding to a pixel number of the solid-state pickup element of the selected one of the various types of electronic endoscopes and corresponding to a display standard for an external computer, parallel-serially converts the digital picture signals, and outputs the converted signals as differential signals,wherein the electronic endoscope apparatus further comprises a high-definition television system converter that detects the pixel number of the digital picture signals based on the differential signals inputted from the differential signal outputting portion, converts the digital picture signals to high-definition television signals based on the detected pixel number and outputs the high-definition television signals, the high-definition television system converter being detachably connected to the differential signal outputting portion, andwherein the differential signal outputting portion and high-definition television system converter are connected with a differential circuit comprising one of a pulse transformer and a capacitor to maintain a predetermined proof pressure.
