Summary:To provide an endoscope system and a method of operating the endoscope system that make it possible to observe an observation target substantially as with the case where a plurality of light sources each independently emitting a light beam having a color different from one another is used as illumination light of continuous spectrum light.SOLUTION: Values calculated based on color-wise integrated light quantity values obtained by receiving V light, B light, G light, and R light respectively by Cy pixel, Mg pixel, Ye pixel, and G pixel, and a light quantity ratio Cv:Cb:Cg:Cr are made to match a ratio of color-wise integrated light quantity values obtained by receiving continuous spectrum light 26 of a xenon lamp by Cy pixel, Mg pixel, Ye pixel, and G pixel.SELECTED DRAWING: Figure 14 【課題】互いに異なる色の光を独立して発光する複数の光源を用いて連続スペクトル光を照明光に用いた場合とほぼ同様に観察対象を観察可能にする内視鏡システム及び内視鏡システムの作動方法を提供する。【解決手段】Ｖ光、Ｂ光、Ｇ光、Ｒ光を、Ｃｙ画素、Ｍｇ画素、Ｙｅ画素、Ｇ画素でそれぞれ受光して得る色毎の光量積分値と光量比Ｃｖ：Ｃｂ：Ｃｇ：Ｃｒとに基づいて算出される値を、キセノンランプの連続スペクトル光２６を、Ｃｙ画素、Ｍｇ画素、Ｙｅ画素、Ｇ画素でそれぞれ受光して得る色毎の光量積分値の比率に一致させる。【選択図】図１４
