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 10 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.

Abstract: A genetic characteristic estimation device (2000) acquires genetic mutation information (30) and position information (40). The genetic mutation information (30) indicates information regarding a genetic mutation in a deoxyribonucleic acid (DNA) sequence of a target cell (20) obtained from a target organism (10). In the position information (40), a position on the DNA sequence is associated with the type of a cell or the type of an organ. The genetic characteristic estimation device (2000) determines a genetic mutation at the position associated with the type of the target cell (20) or the type of an organ including the target cell (20) in the position information (40) from among genetic mutations indicated by the genetic mutation information (30), and computes a genetic characteristic index value representing a genetic characteristic of the target organism (10) based on a characteristic of the determined genetic mutation.
