1. A fluorescence endoscope apparatus comprising: a light source that radiates excitation light and reference light onto an examination target; a fluorescence-image generating portion that generates a fluorescence image by capturing fluorescence generated at the examination target due to irradiation with the excitation light from the light source; a reference-image generating portion that generates a reference image by capturing return light that returns from the examination target due to irradiation with the reference light from the light source; a division-image generating portion that generates a division image by dividing the fluorescence image generated by the fluorescence-image generating portion by the reference image generated by the reference-image generating portion; and a corrected-image generating portion that generates a corrected image based on the division image and the fluorescence image; wherein the corrected-image generating portion generates a corrected image in which a region that has relatively high luminance and that the division image and the fluorescence image have in common is emphasized.
