Information is acquired and a diseased portion is identified more accurately and with high precision regardless of the observation conditions of an examination target and the state (color and shape) of the examination target. Provided is a fluorescence endoscope apparatus (100) including a light source (10) that radiates excitation light and reference light onto an examination target a fluorescence-image generating portion (41) 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 (43) 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 (44) that generates a corrected image based on the division image and the fluorescence image, wherein the corrected-image generating portion (44) 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.
