Abstract: An image processing device includes: one or more processors including hardware. The one or more processors are configured to: calculate, on a basis of a reference image acquired by capturing an image of a reference subject which has an optical characteristic that is equivalent to at least a part of a living body, image transformation parameters through congruence transformation that transforms a coordinate corresponding to a color of target region included in the reference image defined in a color space into a coordinate corresponding to an achromatic color in the color space; and perform, in the color space on a basis of the calculated image transformation parameters, the congruence transformation of colors of a color image acquired by capturing an image of the living body, the color image being constituted by at least two monochromatic image corresponding to different illumination having different center wavelengths.

Abstract: 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.

Abstract: An electrode unit configured to resect or coagulate tissue inside a subject by using a high-frequency current, including: an electrode supporting portion provided with a pair of distal end rigid portions surfaces of which are covered by an electrically insulating material, and an elastic region portion having lower bending rigidity than bending rigidity of each of the pair of distal end rigid portions, the elastic region portion being provided on a proximal end side of each of the pair of distal end rigid portions; and an electrode configured with electrode bodies respectively protruding downward from the pair of distal end rigid portions and an installation portion that installs respective lower ends of the electrode bodies.
