Provided is an image processing device and a fluoroscopy device that can suppress a change in the color of a normal site while making it easy to identify an affected site. Employed is an image processing device 6 including a fluorescence-image generating unit 21 that images fluorescence generated at a subject A irradiated with excitation light and generates a fluorescence image a white-light-image generating unit 20 that images white light returned from the subject A irradiated with illumination light and generates a white-light image a memory 24 that converts the white-light image to a plurality of color signals constituting a color space an image computing unit 25 that corrects the plurality of color signals converted by the memory 24 using at least one color signal among the plurality of the color signals and the fluorescence image an image computing unit 25 that generates a corrected image from the plurality of color signals corrected by the image computing unit 25 and an image combining unit that combines the fluorescence image generated by the fluorescence-image generating unit 21 and the corrected image generated by the image computing unit 25.
