Abstract: A query acquisition unit (610) acquires pose information (hereinafter, described as query pose information) that is information to be a query and indicates a pose of a person. A search information acquisition unit (620) acquires a plurality of pieces of search pose information. The search pose information is pose information about an image (hereinafter, described as a target image) to be a search target, and is stored in a database by a plurality of target images. A selection unit (630) selects, from among the plurality of pieces of search pose information, two or more pieces of the search pose information whose degree of similarity to the query pose information satisfies a reference. The selection processing becomes substantially processing of selecting a target image similar to an image (hereinafter, described as a query image) associated with the query pose information.

Abstract: When a user of a terminal (10) desires to view a desired image, the user inputs a selection condition of the image to the terminal (10). Then, the terminal (10) encodes the selection condition, and displays code information on a screen. Then, when the user causes a capturing apparatus (20) to capture an image of the screen, an image selection apparatus (30) recognizes the selection condition by processing the image (first image). Then, the image selection apparatus (30) transmits an image (second image) that satisfies the selection condition to a predetermined terminal, for example, the terminal (10) that displays the code information.
