A fluorescent imaging device includes a light source unit (11) including a first light source (11a) for radiating excitation light (EL), a second light source (11b) for radiating visible illumination light (VL), and a third light source (11c) for radiating non-visible light (IL), an imager (10) being configured to capture a fluorescent image (41), a visible image (42), and a non-visible image (43), and a tracking processor (32e) that is operable to perform moving-body tracking for a region of interest (51) that is set in an image based on at least the non-visible image.
