• similarity determination unit for determining whether the face image of the matching target person is the face image of the accumulator by comparing the degree of similarity, which is of a matching result of the matching unit, to a predetermined threshold;
• recorder for recording detection of the accumulator, which is of the matching target person, in the accumulator database together with the identification information while correlating the detection of the accumulator with the face image of the accumulator, when the similarity determination unit determines that the face image of the matching target person is the face image of the accumulator;
• population extractor for extracting the number of face images, each of which is recorded together with identification information identifying a predetermined article registered in past times, as the number of persons of a population from pieces of information included in the accumulator database;
• and
• mobile ratio calculator for, assuming that the number of persons of a target group is the number of face images for each article recorded together with the pieces of identification information identifying the currently-registered articles in the pieces of information included in the accumulator database, calculating a ratio of the number of persons of the target group to the number of persons of the population as a mobile ratio of the person who uses or purchases the predetermined article with respect to the currently-registered article, the information processing method comprising:
• an obtaining step of obtaining, in the obtaining unit, the face image of the matching target person who uses or purchases one of the plurality of articles together with the identification information identifying the article that is used or purchased by the matching target person;
• a matching step of performing, in the matching unit, matching by calculating the degree of similarity between the face image of the matching target person, which is obtained in the obtaining step, and the face image of the accumulator, which is stored in the storage;
• a similarity determination step of determining, in the similarity determination unit, whether the face image of the matching target person is the face image of the accumulator by comparing the degree of similarity, which is of the matching result of the processing in the matching step, to the predetermined threshold;
• a recording step of recorder, detection of the accumulator, which is of the matching target person, in the accumulator database together with the identification information while correlating the detection of the accumulator with the face image of the accumulator, when the determination that the face image of the matching target person is the face image of the accumulator is made through the processing in the similarity determination step;
• a population extraction step of extracting, in the population extractor, the number of face images, each of which is recorded together with the identification information identifying the predetermined article registered in past times, as the number of persons of the population from the pieces of information included in the accumulator database;
• and
• a mobile ratio calculation step of, assuming that the number of persons of the target group is the number of face images for each article recorded together with the pieces of identification information identifying the currently-registered articles in the pieces of information included in the accumulator database, in the mobile ratio calculator, calculating the ratio of the number of persons of the target group to the number of persons of the population as the mobile ratio of the person who uses or purchases the predetermined article with respect to the currently-registered article.
