Provided is a fluorescence endoscope device that includes a light source; an image generating portion that captures an image of fluorescence generated at a subject due to irradiation with excitation light from the light source to obtain a fluorescence image and that captures an image of return light returning from the subject due to irradiation with reference light to obtain a reference image; an image-correcting portion that corrects the fluorescence image using the reference image to generate a corrected fluorescence image; an effective-area defining portion that defines an effective area having a brightness in a predetermined variation range in the corrected fluorescence image; a region-extracting portion that extracts a high-brightness region having a brightness higher than or equal to the predetermined threshold in the corrected fluorescence image; and an indication portion that shows whether or not the high-brightness region exists inside the effective area in an identifiable manner.
