Abstract: 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. The present technology is applicable to, for example, an endoscope system for imaging a living body with an endoscope.

Abstract: A feature amount generation unit 26a of an information processing unit 20-1 generates a feature amount indicating the relationship in spectral reflectance between two points, from spectral data of a multispectral image in an irradiation region of a common light source acquired by a multispectral camera 10. A recognition processing unit 27 performs recognition processing on a subject, on the basis of the feature amount generated by the feature amount generation unit 26a, with at least one of the two points regarded as a position in an image area of the subject that is a recognition target in the multispectral image. Therefore, the feature amount generation unit 26a can easily generate the feature amount robust against variation of the light source and appropriate for the subject. In addition, the authentication processing unit 27 can accurately perform the recognition processing even if the light source varies between registration of the subject and the recognition of the subject.

Abstract: There is provided an image processing device including a matching degree calculation unit configured to calculate a matching degree between a pixel value of a target pixel in a standard image of a current frame and a pixel value of a corresponding pixel in a reference image of the current frame, and an estimation unit configured to estimate a disparity between the standard image and the reference image based on a result obtained by calculating the matching degree. The matching degree calculation unit calculates the matching degree using a disparity estimated for the standard image and the reference image of a previous frame.
