Provided is a fluoroscopy apparatus including a light source that irradiates an observation target with reference light and excitation light； a fluorescence-image generating unit that captures fluorescence emitted from the observation target X irradiated with the excitation light to generate a fluorescence image； a reference-image generating unit that captures return light returning from the observation target irradiated with the reference light to generate a reference image； an image-combining unit that superimposes the fluorescence image on the reference image to generate a combined image； a determining unit that determines whether there is a position with a luminance at or below a predetermined threshold in the reference image； and a notifying unit that, if the determining unit determines that there is a position with a luminance at or below the predetermined threshold, provides notification thereof.
