摘要:
A fluoroscopy apparatus including: an illumination unit having a light source radiating illumination light and excitation light onto an observation target, a fluorescence-imaging unit acquiring a fluorescence image by imaging fluorescence generated at the observation target by the excitation light, a white-light-imaging unit acquiring a reference image by imaging light returning from the observation target by the illumination light, and an image-correction unit obtaining a correction fluorescence image by raising the luminance value of the fluorescence image to the power of a reciprocal of a first and second exponent obtained by a power approximation of a distance characteristic of luminance versus observation distance, for the fluorescence image, and that obtains a corrected fluorescence image by dividing the correction fluorescence image by the correction reference image.
