Abstract:
1. An endoscope apparatus comprising: a light source unit including at least one light source generating illumination light and excitation light; an endoscopy scope including, at an end portion thereof, an irradiation section for irradiating the illumination light and the excitation light; a reflected-light imaging unit for detecting reflected light generated as a result of the illumination light being reflected at a tissue; an endoscopic-image generating unit for generating an endoscopic image signal based on a reflected-light signal from the reflected-light imaging unit; a fluorescence-detecting unit for detecting fluorescence generated in the tissue by the excitation light; a fluorescence-image generating unit for generating a fluorescence image signal based on a fluorescence signal from the fluorescence-detecting unit; a ratio-generating unit that generates a ratio between an intensity of the reflected-light signal and an intensity of the reflected light that has been determined in advance from a predetermined distance; and a correcting unit for correcting the fluorescence signal or the fluorescence image signal with the ratio and generating a corrected fluorescence signal or a corrected fluorescence image signal that is not influenced by changes in the distance between the irradiation section and the tissue.
