PROBLEM TO BE SOLVED: To provide an endoscope system capable of correcting change of a hue associated with a wavelength shift of a semiconductor light source.SOLUTION: A light source control part 21 controls a plurality of LED light sources in such a way that, in a normal observation mode, the light source control part 21 performs light source control for a normal observation mode to cause the light sources to emit light for the normal observation mode and that, in a special observation mode, the light source control part 21 performs light source control for the special observation mode to causes the light sources to emit light for the special observation mode. At least any one LED light source of the plurality of LED light sources generates light in which a peak wavelength more shifts as light emission intensity becomes higher. A color conversion part 68 changes a content of color conversion processing according to a drive amount applied to the plurality of LED light sources.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】半導体光源の波長シフトなどに伴う色調の変化を補正することができる内視鏡システムを提供する。【解決手段】光源制御部２１は、通常観察モードにおいて、通常観察モード用の光源制御を行って、通常観察モード用の光を発し、特殊観察モードにおいて、特殊観察モード用の光源制御を行って、特殊観察モード用の光を発するように、複数のＬＥＤ光源を制御する。複数のＬＥＤ光源のうち少なくともいずれか１つのＬＥＤ光源は、発光強度が大きくなる程、ピーク波長がシフトする光を発生する。色変換部６８は、複数のＬＥＤ光源に加える駆動量に応じて、色変換処理の内容を変更する。【選択図】図２
