A fluorescent endoscopy apparatus includes an endoscope insertion unit that is inserted into a body cavity and that guides excitation light to illuminate a region to be observed, and an imaging unit that images a fluorescent image by receiving fluorescence that has been output from the region to be observed by illumination with the excitation light and guided by the endoscope insertion unit. Further, the fluorescent endoscopy apparatus includes a facial information detection unit that detects facial information about a person in an imaging image that has been imaged by the imaging unit by receiving light guided by the endoscope insertion unit, and an interlock unit that prohibits illumination with the excitation light when the facial information detection unit has detected the facial information.
