Abstract:
1. A fluorescence observation apparatus comprising: a light source that emits excitation light for irradiating the vicinity of an examination site; a fluorescence information acquisition unit that acquires information about fluorescence emitted from the vicinity of the examination site through the irradiation with the excitation light from the light source; a residue fluorescence information acquisition unit that acquires information about fluorescence emitted from residues selectively dyed with a fluorescent dye, through the irradiation with the excitation light from the light source; and a fluorescence information correction unit that generates fluorescence information about the examination site in which the fluorescence from the residues is suppressed, based on the fluorescence information from the vicinity of the examination site, acquired by the fluorescence information acquisition unit, and the fluorescence information from the residues, acquired by the residue fluorescence information acquisition unit.
