Observation is performed with a fluorescence image having high quantitativeness by satisfactorily eliminating dependencies on distance and angle that remain in an image that has been subjected to division. Provided is a fluoroscopy apparatus (1) including an illumination portion (4) provided with a light source (3) that radiates illumination light and excitation light a fluorescence imaging unit (18) that acquires a fluorescence image by imaging fluorescence generated at an subject (X) a return-light imaging unit (17) that acquires a reference image by imagine return light returning from the subject (X) and an image-correcting unit (6) that corrects the fluorescence image imaged by the fluorescence imaging unit (18) by using the reference image imaged by the return-light imaging unit (17), wherein the image-correcting unit (6) performs the following processing: FLrevice=A×FLbeforex/B×RLbeforey,where FLrevice is a luminance value of a corrected fluorescence image, FLbefore and RLbefore are luminance values of acquired fluorescence image and reference image, A and B are constants, and x and y are exponents for staying within a permissible error.
