摘要： An endoscope apparatus including: a light source configured to emit illumination light including light in a first wavelength band included in a blue wavelength band, light in a first narrowband included in a green wavelength band, and light in a second narrowband having a same light absorption coefficient of hemoglobin as that of the light in the first narrowband; an imager configured to acquire a first image of an object in the first wavelength band, a first narrowband image of the object in the first narrowband, and a second narrowband image of the object in the second narrowband; and a processor including hardware. The processor is configured to implement acquiring scattering characteristics information based on a comparison result between the first narrowband image and the second narrowband image, and generating an observation image using the first image, the first narrowband image, and the scattering characteristics information.
