Abstract

The challenge is to understand the purchase status of a product by viewers of an advertisement displayed on a display device installed in a store, when the customer is captured by an external imaging device while viewing the advertisement. [Solution] When customer A views an advertisement displayed on the advertisement display device 50, a facial image of customer A is captured by camera 30a, and facial features are obtained from the captured facial image in the terminal device 10 (S1). When customer B purchases a product at the POS terminal 70, a facial image of customer B is captured by camera 30b, and facial features are obtained from the captured facial image in the terminal device 20 (S2). The facial features of customer A and customer B are compared, and if it is determined that they are the same person (S3), the product viewed by the customer on the advertisement display device 50 and the product purchased at the POS terminal 70 are identified. Then, it is determined whether these products are the same or not (S4). If the products are the same, it can be determined that the advertisement display was effective.
