Abstract: An endoscope apparatus includes a detecting section to which an observation image of a subject is sequentially inputted, the detecting section being configured to detect a characteristic region in the observation image based on a predetermined feature value concerning the observation image, and an emphasis processing section configured to apply, when the characteristic region is continuously detected in the detecting section, emphasis processing of a position corresponding to the characteristic region to the observation image of the subject inputted after elapse of a first predetermined time period from a time when the characteristic region is detected.

Abstract: An endoscope image processing apparatus includes a detection section configured to receive an observation image of a subject, to detect a feature region in the observation image based on a predetermined feature value for the observation image, and further to output a parameter relating to an erroneous detection rate of the detected feature region, a notification section configured to notify, to a surgeon, detection of the feature region in the observation image through notification processing and to generate a first display image including the observation image in a case where the feature region is detected by the detection section, and an enhancement processing section configured to generate a second display image in the observation image to allow the surgeon to estimate probability of erroneous detection from a display image in the case where the feature region is detected by the detection section.
