For example, as shown in FIG. 11, the information display unit 114 displays a match mark 3f indicating that the display price of "300 yen" and the registered price of "300 yen" for the product A24 match so as to overlap the display price 3c. , a discrepancy mark 3g indicating that the displayed price "280 yen" does not match the registered price "250 yen" for the product A34 is displayed so as to overlap the displayed price 3c.

According to the captured image P1 shown in FIG. 11, the store clerk can grasp at a glance that the display price of the product A24 is correct and that the display price of the product A34 is incorrect.

The information display unit 114 may display the registered price 3e, the match mark 3f, and the mismatch mark 3g side by side at a position corresponding to the position of the displayed price 3c in the captured image P1. Each of the match mark 3f and the mismatch mark 3g is an example of specific information of the present invention.

The print processing unit 117 causes a print unit (not shown) that prints the price tag 3 to execute print processing. The printing unit may be provided in a handy terminal carried by a store clerk, or may be provided in a facility terminal installed in an office of the facility SH1.

For example, when the displayed price 3c acquired by the displayed price acquisition unit 115 and the registered price 3e acquired by the registered price acquisition unit 113 do not match, the print processing unit 117 detects the AR marker 3a corresponding to the product and the AR marker 3a corresponding to the product. Print processing for printing the price tag 3 including the registration price 3e is executed. FIG. 12 shows an example of the printed price tag 3 corresponding to the product A34. The price tag 3 displays an AR marker 3a associated with the product ID "0014" of the product A34, the product name 3b ("A34"), and the appropriate display price 3c ("250 yen") of the product A34. be. Upon receiving the printed price tag 3, the sales clerk attaches the price tag 3 to the shelf board (see FIG. 3) of the product A34.

Here, the print processing unit 117 may cause the print processing to be executed when a predetermined operation by the store clerk is acquired. For example, the camera 15 captures the gesturing operation of the store clerk. The print processing unit 117 executes the print processing when the gesture operation included in the captured image of the camera 15 is a preset operation. For example, when the store clerk performs an operation of touching the mismatch mark 3g in the captured image P1 shown in FIG.

The predetermined operation is not limited to the gesture operation. As another embodiment, the print processing unit 117 may cause the print processing to be executed when the store clerk presses (button operation) a print button (not shown) provided on the price check device 1 . The print processing unit 117 is an example of the print processing unit of the present invention.

[Price check process]
An example of the price check process executed by the control unit 11 of the price check device 1 according to the second embodiment will be described below with reference to FIG.

The processing of steps S21 to S23 is the same as the processing of steps S11 to S13 of the price check processing (see FIG. 9) according to the first embodiment.

In step S<b>24 , the control unit 11 acquires the displayed price of the product from the image of the price tag 3 included in the captured image P<b>1 acquired from the camera 15 . In the example shown in FIG. 7, the control unit 11 acquires the display price 3c ("300 yen") from the image of the price tag 3 of the product A24, and the display price 3c ("280 yen") of the product A34 from the image of the price tag 3 of the product A34. Yen”).

Next, in step S25, it is determined whether or not the registered price 3e obtained in step S23 and the display price 3c obtained in step S24 match. In the example shown in FIG. 7, the control unit 11 determines that the displayed price of "300 yen" for the product A24 matches the registered price of "300 yen" (see FIG. 5), and determines that the displayed price of the product A34 is "280 yen". It is determined that the registered price “250 yen” (see FIG. 5) does not match. If the registered price 3e and the display price 3c match (S25: Yes), the process proceeds to step S251. On the other hand, if the registered price 3e and the displayed price 3c do not match (S25: No), the process proceeds to step S26.

When the captured image P1 includes a plurality of display prices 3c, the control unit 11 determines in step S25 whether or not there is a display price 3c that does not match the registered price 3e among the plurality of display prices 3c. . If there is at least one displayed price 3c that does not match the registered price 3e among the plurality of displayed prices 3c, the process proceeds to step S26. On the other hand, if all displayed prices 3c match the registered prices 3e, the process proceeds to step S251.

In step S251, the control unit 11 causes the captured image P1 to display a match mark 3f (specific information) indicating that the display price 3c is correct. For example, as shown in FIG. 11, the control unit 11 displays a matching mark 3f indicating that the displayed price of "300 yen" and the registered price of "300 yen" for the product A24 are the same so as to overlap the displayed price 3c. After that, the process moves to step S29.

In step S26, the control unit 11 causes the captured image P1 to display a mismatch mark 3g (specific information) indicating that the displayed price 3c is incorrect. For example, as shown in FIG. 11, the control unit 11 displays a discrepancy mark 3g indicating that the displayed price of "280 yen" and the registered price of "250 yen" do not match for the product A34 so as to overlap the displayed price 3c. After that, the process moves to step S27.

In step S27, the control unit 11 determines whether or not a print instruction to print the price tag 3 with the correct displayed price 3c has been obtained for the price tag 3 of the product with the incorrect displayed price 3c. For example, when a store clerk issues a print instruction using a predetermined gesture operation or a print button, the control unit 11 acquires the print instruction. When the control unit 11 acquires the print instruction (S27: Yes), the process proceeds to step S28. If the control unit 11 does not acquire the print instruction (S27: No), the process proceeds to step S29.

In step S28, the control unit 11 executes print processing for printing the price tag 3 including the AR marker 3a corresponding to the product and the registered price 3e of the product. For example, the control unit 11 determines that the AR marker 3a associated with the product ID "0014" of the product A34, the product name 3b ("A34"), and the appropriate display price 3c ("250 yen") of the product A34 are The indicated price tag 3 is printed (see FIG. 12). Upon receiving the printed price tag 3, the sales clerk attaches the price tag 3 to the front surface of the shelf board (see FIG. 3) of the product A34.

In step S29, the control unit 11 determines whether or not the work has been completed. For example, when the store clerk goes around the product shelves T1 to T16 (see FIG. 2) and finishes checking the prices of all the products, the control unit 11 determines that the work is completed. When the work is finished (S29: Yes), the control unit 11 finishes the price check process. If the work has not been completed (S29: No), the process returns to step S21, and the control unit 11 repeats the above process.

According to the product management system 10 according to the second embodiment, when the displayed price 3c of the price tag 3 matches the registered price 3e, information (specific information) indicating that the displayed price 3c is correct is combined with the captured image P1. When the displayed price 3c of the price tag 3 does not match the registered price 3e, information (specific information) indicating that the displayed price 3c is incorrect is synthesized and displayed on the captured image P1. Therefore, the store clerk can check at a glance whether the displayed price 3c is correct or not.

Further, when the displayed price 3c is incorrect, the price tag 3 with the correct displayed price 3c can be printed, so that the clerk can quickly replace the displayed price 3c. Therefore, it is possible to improve the working efficiency of the price check.

As another embodiment of the present invention, the price check device 1 may be a mobile terminal (for example, a smart phone) possessed by a store clerk. In this case, the store clerk photographs the price tag 3 placed on the product shelf with the camera of his/her portable terminal in the work of checking the displayed price. The mobile terminal executes the above-described process of acquiring an image captured by the camera and checking the display price.

Further, as another embodiment of the present invention, the product management server 2 may include each processing unit of the price check device 1. FIG. In this case, the control unit 21 of the product management server 2 acquires the captured image P1 from the price check device 1, acquires the product ID from the AR marker 3a included in the image of the price tag 3, and extracts the product ID from the product information D1. and display specific information (registered price, discount information, match mark, mismatch mark, etc.) based on the acquired registered price on the display unit 13 of the price check device 1 on the image of the price tag 3. It is displayed at a position according to the display price. Further, the control unit 21 determines whether or not the displayed price and the registered price match, and if the displayed price and the registered price do not match, the printing process of the correct price tag 3 is executed. The product management server 2 may be a POS terminal at the facility SH1, or may be a cloud server.
