<p>Quantitative information of a subject is acquired. Provided is a fluorescence endoscope device (100) including a light source (10) that irradiates a subject with excitation light and white light; an image generator (41) that acquires a fluorescence image by capturing fluorescence generated in the subject irradiated with the excitation light and that also acquires a white-light image by capturing return light returning from the subject irradiated with the white light; an image corrector (43) that corrects the fluorescence image by using the white-light image acquired by the image generator (41) so as to generate a corrected fluorescence image; a threshold-value setting unit (45) that sets a threshold value on the basis of an average value of gradation values of pixels in the corrected fluorescence image generated by the image corrector (43); an image adjuster (51) that increases the contrast in the corrected fluorescence image between an area having gradation values larger than the threshold value set by the threshold-value setting unit (45) and an area having gradation values smaller than the threshold value; and a monitor (50) that displays the corrected fluorescence image whose contrast is increased by the image adjuster (51).</p> |
