Abstract
An endoscope system includes: an insertion portion; an illumination portion that emits a plurality of illuminating lights of different hues to each other; an image pickup portion that picks up an optical image formed by an objective optical system in a distal end portion of the insertion portion; a channel that opens in a distal end portion of the insertion portion; a laser probe that is inserted through the channel and has an irradiation portion in a distal end region; a hue range setting portion that sets a hue range of the laser probe in accordance with a hue of an illuminating light; an image analysis portion that detects a hue range portion in a color image obtained from the image pickup portion; and a control portion that permits laser output only in a case where the hue range portion is detected.
