Provided is a fluoroscopy device that can correct a variation in fluorescence intensity, which is dependent on the observation distance, the observation angle, etc., in a fluorescence image in accordance with the observation conditions. A fluoroscopy device 1 includes a light source 3 that irradiates an observation site X with excitation light and white light a fluorescence-image generating section 21 that acquires a fluorescence image by capturing fluorescence generated in the observation site X irradiated with the excitation light a reference-image generating section 20 that acquires a reference image by capturing return light returning from the observation site X irradiated with the white light an observation-condition determining section 22 that determines the observation conditions of the observation site X on the basis of the reference image acquired by the reference-image generating section 20 a preprocessing section 24 that corrects gradation values of the reference image on the basis of the observation conditions of the observation site X and a fluorescence-image correcting section 25 that generates a corrected fluorescence image by dividing the fluorescence image acquired by the fluorescence-image generating section 21 by the reference image whose gradation values have been corrected by the preprocessing section 24.
