The present invention enables the understanding of a target area of a tissue such as a lesion or vessel in an acquired image even in a case where hemorrhage occurs during surgery. Provided is a fluorescent imaging device (100) which comprises: a light source (10) a fluorescent image generating unit (41) for generating a fluorescent image of a subject that can be obtained due to irradiation with excitation light a reference image generating unit (42) for generating a reference image of the subject that can be obtained due to irradiation with reference light a corrected image generating unit (43) for generating a corrected image that has been corrected so as to highlight pixels in the reference image, said pixels corresponding to pixels with a brightness being equal to or greater than a first threshold in the fluorescent image an image display unit (50) for displaying the reference image or the corrected image a hemorrhagic state determining unit (44) for determining whether or not a hemorrhagic area in the subject that has been detected on the basis of the reference image exceeds a definite scope and a display image switching unit (45) for switching from the reference image, which is to be displayed in the image display unit in a case where the hemorrhagic state determining unit determines that the hemorrhagic area does not exceed the definite scope, to the corrected image, which is to be displayed in the image display unit in a case where the hemorrhagic state determining unit determines that the hemorrhagic area exceeds the definite scope.La présente invention permet la compréhension dune région cible dun tissu, telle quune lésion ou un vaisseau, dans une image acquise même dans un cas où une hémorragie se produit durant une chirurgie.
