Abstract:
1. An endoscope system capturing an image of an object in a coelom, the endoscope system comprising: a spouting portion that spouts a fluorescent agent and a cleaning liquid for cleaning the surface of the object onto the object, the fluorescent agent being accumulated in the object or reacting with a specific substance in the object; a light source portion that emits excitation light for exciting the fluorescent agent spouted from the spouting portion and irradiation light having different spectral characteristics from the excitation light; an optical system that transmits the excitation light or irradiation light from the light source portion to the object; an image capture portion that is disposed at a section inserted into the coelom and that picks up fluorescence emitted from the object by irradiating the object with the excitation light, and light emitted from the object by irradiating the object with the irradiation light and having a different spectrum band from the fluorescence; a spectroscopic portion that is disposed in an optical path between the image capture portion and an end of the section inserted into the coelom and that restrains light having the same spectrum band as the excitation light from entering the image capture portion; and a control portion that controls the spouting portion and the light source portion, wherein the control portion controls the light source portion to emit the excitation light after the spouting portion spouts the fluorescent agent onto the object, and carries out control to spout the cleaning liquid at a predetermined time after the excitation light emission is started.
