| 摘要 |
The present invention acquires a high-precision spectral image. An endoscope provided with: an illumination unit (3) for irradiating illumination light containing light from R, G, and B regions onto biomedical tissue; narrow-band light generation units (F1, F2, F3) for generating two narrow-band lights having an intensity ratio of 1:2 or more for at least each of two wavelength bands among R, G, and B constituting the illumination light; an imaging unit (25) for acquiring each image signal on the basis of the narrow-band light generated by the narrow-band generation unit and the reflected illumination light in the biomedical tissue; and an image generation unit (42) for generating an image on the basis of the image signals acquired by the imaging unit. |
