<p>In order to prevent incorrect information from being given to a doctor and prevent erroneous diagnosis even when a positional displacement occurs between a fluorescence image and a reflected light image, disclosed is a fluorescence observation device (1) provided with a white light image generation unit (17) for generating a white light image (G1) from reflected light of white light applied to an object to be observed (A), a fluorescence image generation unit (18) for generating a fluorescence image (G2) by applying excitation light to the object to be observed (A), a fluorescence image correction unit (23) for normalizing the fluorescence image (G2) by the white light image (G1), a displacement amount calculation unit (21) for calculating the displacement amount (d) of the object to be observed (A) by processing a plurality of white light images (G1) captured at time intervals, a region size calculation unit (22) for calculating the size (D) of a region having a fluorescence intensity of a predetermined threshold or more by processing the fluorescence image (G2), and a control unit (26) for controlling the fluorescence image correction unit (23) such that the normalization of the fluorescence image (G2) is stopped when the displacement amount (d) of the object to be observed (A) with respect to the size (D) of the region is larger than or equal to a predetermined ratio.</p> |
