Abstract: An information processing apparatus (2000) includes a summarizing unit (2040) and a display control unit (2060). The summarizing unit (2040) obtains a video (30) generated by each of a plurality of cameras (10). Furthermore, the summarizing unit (2040) performs a summarizing process on the video (30) and generates summary information of the video (30). The display control unit (2060) causes a display system (20) to display the video (30). Here, the display control unit (2060) causes the display system (20) to display the summary information of the video (30) in response to that a change in a display state of the video (30) in the display system (20) satisfies a predetermined condition.

Abstract: An information processing apparatus (2000) includes a first analyzing unit (2020), a second analyzing unit (2040), and an estimating unit (2060). The first analyzing unit (2020) calculates a flow of a crowd in a capturing range of a fixed camera (10) using a first surveillance image (12). The second analyzing unit (2040) calculates a distribution of an attribute of objects in a capturing range of a moving camera (20) using a second surveillance image (22). The estimating unit (2060) estimates an attribute distribution for a range that is not included in the capturing range of the moving camera (20).
