A lesion can be made distinctive in an acquired fluorescence image so as to allow for accurate diagnosis. There is provided a fluoroscopic device (1) including a light source unit (2) that emits illumination light, which is in a wavelength range to be absorbed by a blood vessel, and excitation light, which generates agent fluorescence by exciting a fluorochrome accumulated specifically in a lesion, to an examination site (S); an image acquisition unit (15, 16) that acquires an image by irradiating the same examination site (S) with the illumination light and the excitation light and photographing the respective reflected light and fluorescence obtained; and an image processing unit (4) that acquires a reference image by smoothing the luminance of the reflected-light image acquired by the image acquisition unit (15, 16) and corrects the fluorescence image on the basis of the acquired reference image.
