Apparatus for displaying result of analogous image retrieval and method for displaying result of analogous image retrieval

A challenge to be met is to make it possible to accurately ascertain a behavior history of a person in various camera environments. Person characteristic data extracted from a plurality of cameras are stored in a person characteristic database. A retrieval request receiving section receives an identifier for identifying a person to be retrieved as a retrieval key. A characteristic retrieval section performs retrieval of persons matching the retrieval key from the person characteristic database in descending order of similarity. A retrieval result grouping section classifies the results of retrieval into units assumed to belong to the same environment. A retrieval result display section displays results of grouping. Since retrieval results are displayed in the form of a list on each unit assumed to belong to the same environment, the person to be retrieved can simply be ascertained in various camera environments despite a limited number of displays provided.
