Abstract

A feature vector creating section creates a feature vector unique to a customer on the basis of the images of a person picked up by cameras in a store. An entrance information storage section stores entrance information obtained by adding the identification code, entrance time, etc. to the feature vector of the incoming person. A customer collating section collates the feature vector of a person leaving and moving around the store with the feature vectors stored in the entrance information storage section. When the collation has found the same customer, the customer's identification code, pickup time, pickup place, and others are stored as traffic-line information into a traffic-line storage section. The route that a customer took is found by picking up pieces of the traffic-line information with the same identification code.
