    Abstract: Provided is a fluoroscopy apparatus that allows examination with a highly quantitative fluorescence image by sufficiently removing the residual dependence on factors such as distance from a divided image. Employed is a fluoroscopy apparatus (100) including a preprocessing section (46) that multiplies at least one of a fluorescence image and a reference-light image by a coefficient by which distance characteristics of fluorescence intensity and distance characteristics of return-light intensity acquired from a standard sample in advance are made directly proportional to each other to generate a correction fluorescence image and a correction reference-light image; a divided-image generating section (43) that divides the correction fluorescence image by the correction reference-light image to generate a divided image; a threshold-setting section (45) that sets a threshold based on a mean grayscale level of pixels in the divided image; an image-adjusting section (51) that enhances contrast between a region with grayscale levels above the set threshold set by the threshold-setting section and a region with grayscale levels below the threshold in the divided image; and a monitor (50) that displays the divided image with the enhanced contrast.

    Abstract: 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).
