Abstract
A mobile terminal obtains image data related to a product posted on a flier by imaging and sends the image data related to the product to a shopping management server. Upon reception of the image data related to the product from the mobile terminal, the shopping management server determines the product by analyzing the image data related to the product, obtains at least one of inventory information and sales information of the product, and sends at least one of the inventory information and the sales information of the product to the mobile terminal. The mobile terminal combines computer-graphics image data indicating at least one of the inventory information and the sales information of the product sent from the shopping management server with an image of the flier in real space and presents the combined image, thereby solving the problem.
