Abstract:
1. An endoscope system comprising: an endoscope that includes a radiation optical system for radiating a beam emitted from a beam source onto a subject and an imaging optical system containing an imaging device for imaging the subject; a control unit to which the endoscope removably connects; a beam source control unit that controls emission beam intensity of the beam source according to a beam quantity specified value input from the control unit; and a type check unit that checks a type of the imaging device mounted on the endoscope which is connected to the control unit, wherein the beam source control unit has a plurality of control patterns for expressing a relationship between the beam quantity specified value and a control output value to be given to the beam source, switches to any one of the control patterns according to the check result obtained by the type check unit, and controls the emission beam intensity of the beam source according to the switched control pattern, the beam source control unit switches the control pattern in linking with a shutter operation of the imaging device, and the type check unit checks the type of the imaging device as to whether the type is a global shutter system or a rolling shutter system.
