A fluorescence distribution image of each fluorescent agent can be acquired from a fluorescent image acquired in a mixed state by using a leading-edge CCD type fluorescence endoscope, and the diagnostic ability of cancer cells is improved. A light source unit that selectively irradiates two or more types of excitation light having different spectral characteristics in order to excite two or more types of fluorescent agents having different optical characteristics in an endoscope system, and a body cavity An imaging unit 14 that is provided in a portion that is placed inside, has a filter that cuts off each of the excitation light, and has light receiving sensitivity in two or more types of fluorescence wavelength bands emitted from the imaging target by each excitation light; A storage unit that stores information on the relative relationship between the fluorescence intensity generated when excited by each excitation light and the concentration of each fluorescent agent, the fluorescence intensity of two or more images taken by the imaging unit, and the storage unit An endoscope system 1 is provided that includes a concentration information calculation unit 18 that calculates and outputs the concentration information of each fluorescent agent based on the information related to the relative relationship.
