Abstract
An endoscope system according to the present invention includes: an illumination light source that emits illumination light for illuminating an object; a therapeutic light source that emits therapeutic light for causing a photoreactive reagent accumulated in a treatment target site to react; a guide light source that emits guide light having a wavelength shorter than a wavelength band of the therapeutic light source; an imager that captures an optical image, the imager including an optical filter that cuts light in the wavelength band of the therapeutic light and transmits a part of white light, the guide light, and fluorescence emitted by the reagent; a controller that controls emission timings of the illumination light source, the therapeutic light source, and the guide light source; and an image processor that generates an image on the basis of an optical image obtained by light emitted from the illumination light source, the therapeutic light source, and the guide light source, in which the controller causes the image processor to generate an illumination light image based on an optical image acquired during a period in which the illumination light source and the guide light source are ON and to generate a fluorescence image based on a fluorescence image acquired during a period in which the therapeutic light source is ON and the illumination light source and the guide light source are OFF.
