Abstract: An information processing apparatus (2000) detects an abnormal region (30) from a moving image frame (14). The abnormal region (30) is a region that is estimated to represent an abnormal part inside a body of a subject. The information processing apparatus (2000) generates and outputs output information based on the number of detected abnormal regions (30).

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 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: An information processing apparatus (2000) detects an abnormal region (30) in each of a plurality of video frames (14) constituting video data (12) in which the inside of a body is captured. The information processing apparatus (2000) outputs output information related to the detected abnormal region (30). Herein, the information processing apparatus (2000) starts outputting of the output information when a detection score based on a proportion of the number of the video frames (14) in which the abnormal region (30) is detected becomes equal to or more than a first threshold value in a state where outputting of the output information is not being performed. Further, the information processing apparatus (2000) ends outputting of the output information when the detection score becomes equal to or less than a second threshold value in a state where outputting of the output information is being performed.
