摘要

The result acquisition unit (23) acquires a detection result indicating the presence / absence of a stationary person and the presence / absence of a moving person for each of the plurality of subregions in which the region included in the image data is divided. The time measuring unit (24) measures the duration of the state indicated by the detection result acquired by the result acquisition unit (23) that there is no stationary person and there is a moving person. The stay determination unit (25) determines whether or not a person is staying in each of the plurality of subregions based on the detection result and the duration measured by the time measurement unit (24).
