Abstract
A system that detects the number of persons waiting in a queue includes an image acquisition unit that acquires a captured image, an analysis unit that detects a person from the captured image, and a decision unit that, when a region in which no person is detected in the captured image has an area greater than or equal to a predetermined area, sets the number of persons detected from the captured image as the number of persons waiting in the queue.
