A fluoroscopy apparatus includes an illumination portion irradiating an observation target with illumination light a fluorescence image acquisition device acquires fluorescence emitted from an observation target to acquire a fluorescence image a fluorescence image-acquisition optical system forms an image of the observation target using the fluorescence a reference-light image acquisition device acquires returning light from the observation region to acquire a reference image a reference-light image-acquisition optical system forms an image using the returning light and an image correction section corrects the fluorescence image by the reference image, wherein the product of an pixel density of the reference-light image acquisition device and the image-forming magnification of the reference-light image-acquisition optical system is less than the product of the pixel density of the fluorescence image acquisition device and the image-forming magnification of the fluorescence image-acquisition optical system.
