摘要:
Observation is performed with a fluorescence image having high quantitativeness by satisfactorily eliminating dependency on distance. Provided is a fluoroscopy apparatus (101) including an illumination unit (20) having a light source (10) that radiates illumination light and excitation light onto an observation target site (X), a fluorescence-imaging unit (42) that acquires a fluorescence image by imaging fluorescence generated at the observation target site (X) by the radiation of excitation light, a white-light-imaging unit (44) that acquires a reference image by imaging return light returning from the observation target site (X) by the radiation of the illumination light, and an image-correction unit (60) that obtains a correction fluorescence image by raising the luminance value of the fluorescence image to the power of a reciprocal of a first exponent obtained by a power approximation of a distance characteristic of luminance versus observation distance, for the fluorescence image, that obtains the correction reference image by raising the luminance value of the reference image to the power of a reciprocal of a second exponent obtained by a power approximation of a distance characteristic of luminance versus observation distance, for the reference image, and that obtains a corrected fluorescence image (K) by dividing the correction fluorescence image by the correction reference image.
