Abstract: An assistant device includes a processor configured to: generate a first image including one or more characteristic regions requiring excision by a surgical operator; generate a second image including one or more cauterized regions cauterized by an energy device; generate information regarding presence or absence of a first region that is included in the characteristic regions and that is not included in the cauterized region based on the first image and the second image; and output information indicating the presence of the characteristic regions that requires to be cauterized when the first region is present.
