The display control apparatus 10 communicates with the display apparatus 20 via the network interface 1060. Further, the display control apparatus 10 may communicate with the stock management apparatus 50 via the network interface 1060.

FIG. 7 is a diagram illustrating one example of a flowchart illustrating processing to be performed by the display control apparatus 10 illustrated in FIG. 2. In the example illustrated in FIG. 7, the display control apparatus 10 operates together with the stock management apparatus 50. Further, the stock management apparatus 50 stores in advance a reference number illustrated in FIG. 4. For example, in a case where a reference number is different for each product, the stock management apparatus 50 stores the reference number for each piece of product identification information.

When a customer purchases a product in a store, the product checkout apparatus 40 transmits, to the stock management apparatus 50, product identification information and a purchase quantity of the product. Then, the stock management apparatus 50 reduces the stock quantity associated with the product identification information received from the product checkout apparatus 40 by the received purchase quantity (step S10). Then, the stock management apparatus 50 determines whether the stock quantity after updating is equal to or less than a reference value (step S20). In a case where the stock quantity is equal to or less than the reference value, the stock management apparatus 50 transmits, to the display control apparatus 10, the product identification information and the stock information of the product (step S30). Herein, the stock information to be transmitted includes the stock quantity.

The stock information acquisition unit 110 of the display control apparatus 10 acquires the product identification information and the stock information transmitted from the stock management apparatus 50. Subsequently, the apparatus information acquisition unit 120 reads, from the apparatus information storage unit 140, display apparatus identification information associated with the product identification information acquired by the stock information acquisition unit 110 (step S40). Then, the display control unit 130 changes a display pattern of the display apparatus 20 associated with the display apparatus identification information read in step S40, by using the stock information acquired by the stock information acquisition unit 110 (step S50). Specifically, the display control unit 130 reads information associated with the stock information from the display information storage unit 150, and changes the display pattern of the display apparatus 20 according to the information (step S50).

In this way, according to the present example embodiment, the display control apparatus 10 changes a display pattern of a display apparatus by using information related to stock of a product. Therefore, the display control apparatus 10 can provide a salesperson or an employee in a store of information related to a product associated with a display apparatus 20 via the display apparatus 20.
