Abstract: The acquisition unit 41B acquires a target image indicating a target object of inspection. The detection unit 42B detects, on the basis of a group of images each of which indicates the target object in a normal state, the target image that indicates the target object that is not in the normal state among the target images that the acquisition unit 41B acquires.

Abstract: In the endoscopic examination support apparatus, the image acquisition means acquires an endoscopic image taken by an endoscope. The first lesion detection means detects a lesion candidate from the endoscopic image, using a machine learning model that learned a relationship between the lesion candidate and a normal state of a large intestine. The second lesion detection means detects a lesion candidate from the endoscopic image, using a machine learning model that learned a relationship between the lesion candidate and a predetermined state of the large intestine. The output means outputs at least one of a detection result of the first lesion detection means and a detection result of the second lesion detection means.

Abstract: In a video editing device, a video acquisition means acquires an endoscopic video taken by an endoscope. A first timing acquisition means acquires a first timing at which a lesion is detected from the endoscopic video. A second timing acquisition means acquires a second timing at which an examiner instructs photographing based on the endoscopic video. An editing means generates an edited video by extracting, from the endoscopic video, a partial video of a predetermined time period before and after a timing corresponding to at least one of the first timing and the second timing, and output the edited video.

Abstract: The endoscopic image acquisition means acquires an endoscopic image. The still image acquisition means acquires a plurality of still images obtained by imaging a lesion included in the endoscopic image. The identity determination means determines an identity of the lesion included in the plurality of still images. The selection means selects a representative image that best represents the lesion, from a plurality of still images determined to correspond to the same lesion, and displays the representative image on the display device.

Abstract: The image acquisition means acquires a captured image by an endoscope. The position acquisition means acquires positional information of the endoscope. The lesion detection means detects a lesion from the captured image. The washing degree determination means determines a degree of intestinal tract washing from the captured image. The reaching determination means determines that the endoscope reaches a cecum from the captured image. The end determination means determines an end timing of an examination by the endoscope. The calculation means calculates an observation time based on a timing that the endoscope reaches the cecum and the end timing. The report generation means generates an examination report including the observation time, the degree of intestinal tract washing, a presence or absence of reaching the cecum of the endoscope, and a detection result of the lesion including the positional information of the lesion. The generated examination report is displayed on the display device.

Abstract: The position detection means detects a position of an endoscope based on an endoscopic image or the like. The speed estimation means estimates a withdrawal speed of the endoscope based on the acquired position of the endoscope. The display control means displays information indicating a region of interest, which is a region where the withdrawal speed was equal to or higher than a predetermined threshold value, on a display device based on the position of the endoscope and the withdrawal speed.
