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 (G 2 ) of fluorescence generated in the subject (A); a return-light image acquisition section (17) that acquires a reference image (G 1 ) 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 (G 2 ) acquired by the fluoroscopic image acquisition section (18) by using the reference image (G 1 ). 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 (G 1 ) and the fluoroscopic image (G 2 ) by using the correction coefficient as an index, and divides the correction fluoroscopic image by the correction reference image. |
