Observation is performed by using a highly-quantitative fluoroscopic image obtained after any distance dependence remaining in a divided image is sufficiently eliminated. Provided is a fluoroscopy apparatus (1) that includes an illumination section (4) that includes a light source (3) for radiating illumination light and excitation light onto a subject (A) a fluoroscopic image acquisition section (18) that acquires a fluoroscopic image (G2) of fluorescence generated in the subject (A) a return-light image acquisition section (17) that acquires a reference image (G1) of return light returning from the subject (A) a distance-information acquisition section that acquires information about a distance between the return-light image acquisition section (17) and the subject (A) and an image correction section (24) that corrects the fluoroscopic image (G2) acquired by the fluoroscopic image acquisition section (18) by using the reference image (G1). The image correction section (24) sets a correction coefficient based on the distance information, generates a correction reference image or a correction fluoroscopic image by performing a power calculation for light intensity information of at least one of the reference image (G1) and the fluoroscopic image (G2) by using the correction coefficient as an index, and divides the correction fluoroscopic image by the correction reference image.
