Description

The present invention relates to a system for preventing crimes in a sales floor in a store by using images captured by a camera.

In a conventional sales floor security system, a surveillance camera provided near a ceiling in a store captures an image of the sales floor, and the captured video of the sales floor is displayed on a monitor near the cash register (for example, Patent Document 1). By notifying the monitor that the sales floor is being photographed, crimes in the sales floor are prevented. However, in the conventional system, the surveillance camera and the monitor have to be separately installed and connected, and the large-scale installation work and the cost hinder the promotion of the system installation to the store.

An object of the present invention is to improve the inconvenience of the conventional example, and particularly to provide a system that can be introduced into a store more easily than before.

In order to solve this problem, the present application provides a sales floor security program for a tablet terminal having a front camera on the same surface as a display device. The sales floor security program of the present invention causes the information processing unit of the tablet terminal to execute a process of displaying the video of the sales floor input from the front camera on the display device in real time. According to this, unlike the conventional security camera system in which the surveillance camera is installed near the ceiling and the monitor is installed near the cash register, shooting and display can be performed with a single tablet terminal.

Therefore, according to the present invention, it is possible to introduce the sales floor crime prevention system into a store more easily than before.

FIG. 1 is a sales floor configuration example showing an embodiment of the present invention. FIG. 2 is a schematic configuration diagram of the tablet terminal shown in FIG. 1. FIG. 3 is a flowchart of crime prevention processing executed by the tablet terminal of FIG.

Hereinafter, embodiments of the present invention will be described. As shown in FIG. 1A, the sales floor security system of the present embodiment is configured by installing a tablet terminal 10 in which a dedicated application (application software) is installed on a product display shelf S in the sales floor. The above dedicated app is called a security camera app. The tablet terminal 10 includes the front camera 1 on the same surface as the display device 2.
As shown in FIG. 1B, the tablet terminal 10 is fixed to the display shelf S via the fixing means 21. In the present embodiment, the fixing means 21 is a cylindrical rod member. The tablet terminal 10 is stored in the anti-theft case 20. One end of the fixing means 21 is fixed to the anti-theft case 20. The other end of the fixing means 21 is fixed to the display shelf S. The connecting portion between the anti-theft case 20 and the fixing means 21 is a mechanism capable of rotating the anti-theft case 20 around the fixing means 21 which is a cylindrical rod as a rotation axis. By rotating the anti-theft case 20, the angle of the tablet terminal 10 is adjusted so that the field of view of the front camera 1 captures a visitor who visits the vicinity of the display shelf S in which the tablet terminal 10 is installed. The anti-theft case 20 can supply power to the tablet terminal 10 from the outside by a power cord 22.

FIG. 2 shows an outline of the hardware configuration of the tablet terminal 10. The tablet terminal 10 includes an information processing unit 4 including a processor, a chipset, and a RAM (main storage device). Further, it includes the front camera 1 described above, the display device 2 described above, and the touch panel 3 functioning on the display device 2. Further, it is provided with a built-in storage 5 (auxiliary storage device), an external memory 6 (auxiliary storage device), and a communication device such as Wi-Fi. Illustration of other equipment (audio, etc.) equipped in a general tablet terminal is omitted.

Next, an operation realized by the information processing unit 4 executing the security camera application will be described. The security camera application is installed from the external memory 6. It may be downloaded and installed by the communication device 7. The security camera application provides various functions, and FIG. 3 shows a flowchart of the security processing. When the security camera application is executed on the tablet terminal 10 and the security processing of its functions is activated, the information processing unit 4 displays the image input from the front camera 1 on the display device 2 in real time (S1). .. In the meantime, the information processing unit 4 reads the shooting cycle of the still image and the setting data for valid/invalid of the moving body detection from the setting information stored in advance in the built-in storage 5 and inspects the valid/invalid of the moving body detection (S2). .. When the moving body detection is valid, the information processing unit 4 executes the moving body detection (S3) based on the image input from the front camera 1. When the moving object is detected, the information processing section 4 inspects the arrival of the read imaging cycle (S4). The information processing unit 4 also proceeds to the process of S4 when the moving body detection is invalid in S2. When the moving body is not detected in S3, the information processing section 4 repeats the processing from S1. When the information processing unit 4 detects the arrival of the shooting cycle in S4, the front camera 1 shoots a still image on the sales floor and stores the data of the shot still image in the internal storage 5 (S5). This still image is called a shooting still image. After that, the information processing section 4 repeatedly executes the processes of S1 to S5. Even if the arrival of the shooting cycle is not detected in S4, the information processing section 4 repeats the processing from S1.

By the above processing, when a visitor visits the sales floor and enters the field of view of the front camera 1 and takes an image, the image of the visitor is displayed on the display device 2 of the tablet terminal 10 in real time. In addition, the photographed still images showing the visitors are accumulated in the built-in storage 5 of the tablet terminal 10.

Even if a visitor who visits the sales floor has an intention of a crime, he/she finds himself/herself photographed on the display device 2 of the tablet terminal 10 installed on the display shelf, and is aware of the crime. Can be prevented. Since a person who intends to commit a crime can directly see the video, the effect of suppressing the crime is enhanced.

The above-mentioned crime prevention effect can be obtained simply by installing the tablet terminal 10 that executes the crime prevention camera application on the display shelf of the sales floor. There is no need for installation work of the surveillance camera near the ceiling, installation work of a separate surveillance monitor, and connection work between the surveillance camera and the surveillance monitor as in the conventional case. Since no large-scale installation work is required and cost can be reduced, it is possible to install a sales floor security system in a store more easily than before.

The information processing unit 4 provides various functions other than the above by executing the security camera application. Each function will be described below.

[Setting function such as shooting cycle]
The information processing unit 4 records the settings such as the shooting cycle input from the touch panel 3 in the setting information of the internal storage 5. The setting information includes a shooting cycle, a user authentication password, valid/invalid of the motion detection function, valid/invalid of the POP display function, and the like. As the shooting cycle is set shorter, the number of shot still images per unit time can be increased. On the other hand, the longer the shooting cycle is set, the more the recording area of the internal storage 5 can be saved. The optimum shooting cycle can be set according to the environment. The information processing unit 4 may display the setting menu screen on the display device 2 through a predetermined user authentication process immediately after starting the security camera application.

[Motion detection function]
As described above, when the moving body detection function is set to be effective, the information processing unit 4 executes the moving body detection process for detecting the moving body from the image captured by the front camera 1. In this case, the information processing unit 4 executes the processing of S4 to S5 of FIG. 3 only while detecting the moving body by the moving body detection process.

[Resume function]
The information processing unit 4 turns off the screen display of the display device 2 when the moving object detection process does not detect a moving object for a preset period of time. It is possible to suppress image sticking of the display device 2 and suppress deterioration of the display device 2.

[Image search function and thumbnail display function]
The information processing unit 4 associates the captured still image stored in the built-in storage 5 with the captured date and time and records it. When the information processing unit 4 receives a request for image search from the touch panel 3, the information processing unit 4 displays a search screen on the display device 2 for accepting input of a date and time range as a search condition. The information processing unit 4 searches the built-in storage 5 for captured still images corresponding to the date and time range input on the search screen, and retrieves the plurality of retrieved still images for each unit time (for example, for every one minute). ) Grouping, and displaying a representative thumbnail image representing each group (for example, a thumbnail image of the first captured still image within a unit time) on the display device 2. When the representative thumbnail image displayed on the display device 2 is clicked on the touch panel 3, the information processing unit 4 displays on the display device 2 an individual thumbnail image of each captured still image included in the group corresponding to the clicked representative thumbnail image. indicate. When the individual thumbnail image displayed on the display device 2 is clicked on the touch panel 3, the information processing unit 4 reads the captured still image corresponding to the clicked individual thumbnail image from the built-in storage 5 and displays it on the display device 2.

[Storage period of captured still images]
When the remaining amount of the built-in storage 5 becomes less than a certain amount, the information processing unit 4 may delete from the built-in storage 5 in order from the taken still image with the oldest shooting date and time.

[Exporting still images to external memory]
When the information processing unit 4 is requested by the touch panel 3 to write the photographed still image to the external memory 6, the information processing unit 4 displays a selection screen on the display device 2 in which the photographed still image to be written can be selected for each photographing date. The information processing unit 4 records, in the external memory 6, one or a plurality of photographed still images corresponding to the photographing date and time selected from the touch panel 3 on the selection screen, in a file of a general image format.

[POP display function]
When the information processing unit 4 enters a mode in which a POP moving image (advertisement screen) should be displayed on the display device 2, the information processing unit 4 displays the POP moving image prestored in the external memory 6 on the display device 2. The information processing unit 4 may repeatedly execute the processing of S2 to S5 in FIG. 3 during the POP moving image display.

The present invention is not limited to the above embodiments. For example, in order to obtain the crime prevention effect, it is not always necessary to record the photographed still image in the built-in storage 5. The installation location of the tablet terminal 10 is not necessarily limited to the product display shelf. The information processing unit may output sound from the tablet terminal when executing the POP display function or the like. The information processing unit may acquire ambient sound from the microphone of the tablet terminal and store the sound in the built-in storage when performing security processing. The information processing unit may save various information, which is supposed to be saved in the built-in storage, in the external memory instead of the built-in storage.
