  In the above configuration, the CPU 50 executes the control program, and as shown in FIG. 2, the image capturing unit 51, the barcode reading unit 52, the service determining unit 53, the service display detecting unit 54, It functions as a notification unit 55 and an information output unit 56.

FIG. 3 is a diagram illustrating an example of the relationship between the imaging area and the reading area of the camera.
In FIG. 3, the outer frame is an image area AR that is an area that can be captured by the camera 20 in one frame and that is treated as an area where code reading is possible.
The image area AR is arranged at the center of the image area AR, and is arranged around the first reading area AR1 and the first reading area AR1 where extraction is permitted for both the barcode BC and the service display member SD. And a second reading area AR where extraction of the barcode BC is prohibited.
In this case, it is assumed that the service display member SD is attached to the vicinity of the barcode (in the case of FIG. 3, the upper left position of the barcode).

FIG. 3 shows a case where an image of the barcode BC is included in the first reading area AR1, and an image of the service display member SD is included in the second reading area AR2.
The CPU 50 functioning as the image capturing unit 51 controls the camera controller 49 to cause the camera 20 to perform an image capturing operation and capture the captured image. Further, when receiving an instruction from the service display detection unit 54, the image capturing unit 51 stores the image in the imaging area AR captured by the camera 20 in the image work area of the RAM 43, as shown in FIG.

The barcode reading unit 52 converts an image that is considered to be a barcode BC from the image in the first reading area AR1 arranged at the center of the image area AR of the image captured by the image capturing unit 51 into pattern recognition or Detection is performed by recognition processing such as object recognition, and a code symbol corresponding to the barcode is extracted to generate a code symbol.

Other examples of the service display member SD include a discount label that displays a discount rate (for example, 30% discount) at the time of purchase of the product, and a premium for the number of customers who have purchased the product 60 from the normal number of points granted. A point premium label that displays the number of points given in this way can be considered.

Next, the operation of the first embodiment will be described.
FIG. 4 is a processing flowchart of the embodiment.
First, the CPU 50 functions as the image capturing unit 51, controls the camera 20 via the camera controller 49, and acquires an image (step S11).
Subsequently, the CPU 50 functions as a barcode reading unit 52, and among the images captured by the image capturing unit 51, pattern matching or image matching is performed on an image considered to be barcode BC from an image region corresponding to the first reading region AR1. A code symbol detected by object recognition and corresponding to the barcode is extracted (step S12).

Next, the CPU 50 functioning as the barcode reading unit 52 determines whether or not the barcode image is included in the captured image based on whether or not the code symbol has been extracted (step S13).
If it is determined in step S13 that the code symbol cannot be extracted and the bar code BC image is not included in the captured image (step S13; No), the process proceeds to step S11 again. Thereafter, the same processing is repeated.

If it is determined in step S13 that a code symbol can be extracted and the captured image includes a barcode BC image (step S13; Yes), a barcode reading process based on the code symbol is performed and the barcode is displayed. An information code corresponding to BC (product code = “21012345567890” in this embodiment) is generated (step S14).
Subsequently, in the barcode reading process, the CPU 50 determines whether or not reading has been completed, that is, whether or not a code symbol has been extracted from the read image and an information code has been generated (step S15).

  If it is determined in step S15 that a code symbol has been extracted from the read image and an information code has been generated and it has been determined that reading has been completed (step S15; Yes), the service display detection unit 54 functions. The CPU 50 performs the first reading area AR1 and the second reading area AR2 of the image stored in the image work area of the RAM 43 by the image capturing unit 51, that is, the entire image area AR by pattern matching and object recognition. An image is extracted (step S16).

Next, the CPU 50 functioning as the service display detection unit 54 determines whether or not the service display member SD is included in the image area AR (first reading area AR1 + second reading area AR2) (step S17).
If it is determined in step S17 that the service display member SD is included in the image area (step S17; Yes), the CPU 50 functions as the service display detection unit 54, performs the service display reading process, and displays the service display. A service code corresponding to the member (in this embodiment, a service code corresponding to “50 yen discount”) is generated (step S18).
Subsequently, the CPU 50 functions as the service determination unit 53, and determines whether or not the reading of the service display member SD is completed and a service code is generated (step S19).

  If the service display member SD has been read and a service code has been generated in the determination in step S19 (step S19; Yes), an information code (in this embodiment) that is a service provision target corresponding to the service code. , Product code) exists. Accordingly, the CPU 50 functioning as the information output unit 56 sends an information code (product code) to the POS terminal device 12 via the communication I / F 44 so that service registration (discount registration) can be performed in the POS terminal device 12 as service sales. The service code corresponding to the service display member (in this embodiment, a code corresponding to a half price discount) is output (step S20).

  If it is determined in step S19 that the service display member SD is present but the service code cannot be generated (step S19; No), an error notification such as prompting the operator to input the service code is performed and the process is terminated. (Step S21).

FIG. 5 is an explanatory diagram of an image example when a service display member is not detected.
If the service display member SD is not included in the image area in the determination in step S17 (step S17; No), the actually acquired image has a state as shown in FIG. Therefore, the CPU 50 functions as the information output unit 56 so that normal registration can be performed in the POS terminal device 12 as normal sales without service sales, and the information code is sent to the POS terminal device 12 via the communication I / F 44. (Product code) is output (step S22).

FIG. 6 is an explanatory diagram of an image example in an unreadable state.
If it is determined in step S15 that reading of the barcode BC cannot be completed (step S15; No), the actually acquired image is in a state as shown in FIG. 6, for example. Then, an error notification such as prompting the operator to re-read is performed (step S21).
As described above, according to the first embodiment, when the service display member SD attached in association with the barcode BC is present in the vicinity of the barcode BC, it is reliably detected. Therefore, the registration process is not performed in the POS terminal device 12 with only the information code corresponding to the barcode BC, and the service to be provided can be reliably provided.

  That is, when the code symbol (bar code BC) is located in the first reading area AR1, the entire image of the service symbols arranged in a predetermined range around the code symbol (bar code BC) is displayed in the image reading area. Since it is included in the AR, the service symbol (service display member SD) arranged within the predetermined range is not read, only the code symbol (barcode BC) is not read and processed, and the code is surely received. The symbol (barcode BC) and the service symbol (service display member SD) can be processed together.
