Abstract: In the endoscopic examination support apparatus, the image acquisition means acquires captured images during removal of an endoscope. The posture change estimation means estimates a relative posture change of an endoscope camera from the captured images. The distance estimation means estimates a distance between a surface of colon and the endoscope camera from the captured images. The intestinal tract direction estimation means estimates an intestinal tract direction of the colon based on the posture change and the distance. The calculation means calculates a direction in which the endoscope camera should be directed, based on the intestinal tract direction and the relative posture of the endoscope camera. The output means outputs a display image including the direction in which the endoscope camera should be directed, to a display device. The display image can be used for support such as user's decision making.

Abstract: In the endoscopic examination support apparatus, three three-dimensional model generation means generates a three-dimensional model of a luminal organ in which an endoscope camera is placed, based on endoscopic images acquired by imaging an interior of the luminal organ with the endoscope camera. The unobserved area detection means detects an area estimated not to be observed by the endoscope camera, as an unobserved area, based on the three-dimensional model. The display image generation means generates a display image including information indicating an observation achievement degree for each of a plurality of sites of the luminal organ, based on the detection result of the unobserved area. The endoscopic examination support apparatus may be used to support user's decision making.

Abstract: An information processing device includes: a first acquisition unit configured to acquire a capturing time of a lesion image instructed to be saved by a user, from a series of images captured by an endoscope during examination with the endoscope; a second acquisition unit configured to acquire a capturing time of a lesion image detected by detection processing for the series of images captured by the endoscope during the examination; and a display control unit configured to cause a display device to display a first capturing time and a second capturing time which are plotted on a time axis, the first capturing time being the capturing time acquired by the first acquisition unit, the second capturing time being the capturing time acquired by the second acquisition unit.
