Endoscope system and method of unifying picture images in an endoscope system

摘要

This endoscope system comprises a plurality of types kind of endoscope apparatuses, a signal processing apparatus used in common with the plurality of types of endoscope apparatuses and which processes the output signal of the imaging apparatus of each endoscope apparatus to be a video signal and an apparatus for unifying the picture image in the signal output from the plurality of kinds of endoscope apparatus to be a right image or a mirror image and inputs the unified signal into the signal processing apparatus. The plurality of types of endoscope apparatuses have each an elongate insertable part, an image forming optical system provided in the tip part of the insertable part and an imaging apparatus imaging the object image formed by the image forming optical system. At least one endoscope is different from the other endoscopes in whether the image formed by the image forming optical system is a right image or a mirror image. A method of unifying the picture image in the signal output from the signal processing apparatus to be a right image or a mirror image includes unifying the picture image in the signal output from the endoscope apparatus into a right image or a mirror image before it is input into the signal processing apparatus.
