Abstract: A surveillance apparatus (2000) includes a first calculation unit (2020), an extraction unit (2040), and a notification unit (2060). The first calculation unit (2020) calculates a risk index value in a first region (40) on a current route (20). The risk index value of the first region (40) indicates a degree of concern that a risk (such as crowd confusion) caused by congestion of people occurs in the first region (40). For calculation of the risk index value in the first region (40), a captured image generated by a camera (50) is used. The extraction unit (2040) extracts a bypass route (30) when the risk index value of the first region (40) is equal to or greater than a predetermined threshold value. The notification unit (2060) notifies a user that a route through which a person is caused to pass is to be switched to the extracted bypass route (30).

Abstract: Provided is an image processing apparatus (2000) including an index value calculation unit (2020) and a presentation unit (2040). The index value calculation unit (2020) acquires a plurality of images captured by a camera (3000) (captured images), and calculates an index value indicating the degree of change in the state of a monitoring target in the captured image, using the acquired captured image. The presentation unit (2040) presents an indication based on the index value calculated by the index value calculation unit (2020) on the captured image captured by the camera (3000).

Abstract: When the presence of a subject is detected within the image-capturing range of an image sensor, a frame image is created to acquire the identifier of a corresponding product. A feature quantity of the frame image is stored in a storage device in connection with the acquired identifier, and product information associated with the identifier is acquired from a product information DB to perform sales processing.

Abstract: An image acquisition unit (2) acquires an image obtained by capturing at least eyes of a target person. An object specifying unit (4) specifies an object in a line-of-sight direction of the target person using the acquired image. An incident light amount calculation unit (6) calculates an incident light amount representing an amount of light incident on the eyes of the target person using the acquired image. A reference pupil size determination unit (8) determines a reference pupil size based on the calculated incident light amount. A pupil size calculation unit (10) calculates a pupil size of the target person using the acquired image. An interest determination unit (12) determines an interest of the target person in the object by comparing the determined reference pupil size with the calculated pupil size.
