Patent ID: 7713192

Claim:
An endoscope system provided with an image-pickup element at a distal end of an insertion section, comprising: a signal processing circuit for performing various image signal processings on an image signal from the image-pickup element; a plurality of LED illumination built-in type optical adapters each including image-formation optical system means, adapter discrimination means, and LED illumination means, the plurality of optical adapters being detachably and selectively provided to a distal end of an endoscope section; and an apparatus main body including an image processing section for receiving an image signal from the signal processing circuit and performing predetermined signal processing on the image signal, an adapter detection section for detecting the adapter discrimination means of the optical adapters, and control means for controlling the whole endoscope system, wherein at least driving control of the LED illumination means and various signal processing controls on the image signal obtained by the image-pickup element are performed based on the detection result of the adapter discrimination means by the adapter detection section.
