Abstract: An information processing apparatus (2000) acquires a shelf rack image (12) in which a product shelf rack on which a product is displayed is imaged. The information processing apparatus (2000) performs image analysis on the shelf rack image (12), and generates information (actual display information) relevant to a display situation of the product on a product shelf rack (20). The information processing apparatus (2000) acquires reference display information representing a reference for display of the product on the product shelf rack (20). The information processing apparatus (2000) compares the actual display information generated by performing the image analysis on the shelf rack image (12) with the acquired reference display information, and generates comparison information representing a result.

Abstract: According to the present invention, there is provided an information processing system (100) including an acquisition unit (11) that acquires an image, which is generated by a camera, of a face, a selection unit (14) that extracts a person in the acquired image, and selects a person who performs a settlement process based on at least one of a distance from a checkout apparatus, an appearance frequency, and an appearance period of time in a case where a plurality of persons are extracted, an identification unit (12) that identifies the selected person based on the image in which the person is included, and database information in which a feature value of a face is registered, a settlement unit (checkout unit (21)) that performs the settlement process with respect to the identified person.
