Problem to be solved: to provide an endoscope system capable of identifying a plurality of observation objects in which peaks of spectral absorption such as blood, bile, and fat are close to each other.The first illumination light having the first peak wavelength range and the second illumination light having the second peak wavelength different from the first peak wavelength range are automatically switched to emit light.The first observation object having the first absorption peak in the first peak wavelength range of the first illumination light and the second observation object having the second absorption peak in the second peak wavelength range of the second illumination light are respectively identified by the synthesized display image.Diagram【課題】血液、胆汁、及び、脂肪など、分光吸収のピークが近接している複数の観察対象を識別可能に表示することができる内視鏡システムを提供する。【解決手段】第１ピーク波長範囲を有する第１照明光と、第１ピーク波長範囲と異なる第２ピーク波長を有する第２照明光とを自動的に切り替えて発光する。第１照明光の第１ピーク波長範囲に第１吸収ピークを持つ第１観察対象、及び、第２照明光の第２ピーク波長範囲に第２吸収ピークを持つ第２観察対象を、それぞれ合成表示画像にて識別可能にする識別処理を行う。【選択図】図９
