An information processing apparatus, an information processing method, and an endoscope system capable of providing an optimal video image to an operator in accordance with surgical scenes are provided. A processing mode determination unit determines, in accordance with surgical scenes, a processing mode for an in-vivo image captured by an imaging apparatus including an imaging element arranged so as to enable pixel shift processing, and an image combining unit processes an image output from the imaging apparatus, in accordance with the processing mode.

Information processing apparatus, information processing method, and endoscope system for processing images based on surgical scenes

Provided are an image processing apparatus and an image processing method that process a far-infrared image. The image processing apparatus includes a region extraction section, a modal transformation section, and a superimposition section. The region extraction section extracts a region of interest within a visible-light image captured by a visible-light camera. The modal transformation section receives an image of the region of interest within an infrared image captured by an infrared camera observing the same subject as the visible-light camera, and transforms the received image to a modal image. The superimposition section generates a presentation image by superimposing the modal image on the region of interest within the visible-light image. The modal transformation section transforms a far-infrared image of the region of interest to a modal image including an information modal familiar to humans by using, for example, a database and a conditional probability distribution.

A wavelength of light optimum for analysis of a target is specified as an effective wavelength from a multispectral image of the target on which white light is applied, and light of the effective wavelength is applied upon the target. The target in this state is captured as a multispectral image, and the target is analyzed on a basis of a spectral image of an effective wavelength.
