It is explanatory drawing of the screen display operation in 0A. The monitoring cameras 40A to 40D, the monitor device 42, and the VTR 44 are previously set.
Are operating, video signals are output from the surveillance cameras 40A to 40D, and the monitor device 42 displays, for example, an image captured by each surveillance camera by dividing the screen into four.
It is assumed that this 4-division video is recorded by the VTR 44. When there is a dedicated monitoring staff, the inside and outside of the store can be monitored by the monitor device 42, and if the video recorded before is reproduced by the VTR 44, the previous situation such as the previous day can be grasped. Here, it is assumed that the VTR 44 is not reproduced yet. The video signals output from the surveillance cameras 40A to 40D are transmitted via the video line 460 to P
A / D provided in the terminal body 112 of the OS terminal 100A
The signals are input to the converters 118 to 124, individually A / D converted, and written in the video RAMs 130 to 136 as digital images.

However, when the terminal main body 112 is in the single display mode of the POS operation image in advance, the image reading / conversion control unit 154 causes the video RAM 130 to operate under the instruction of the main body processing unit 114.
No image is read out from any of the above-mentioned elements 136 to 136, and the analog image signal of only the synchronization signal is output from the image conversion unit 156. The switch 158 is switched to the b side by the instruction of the main body processing unit 114, but when the code such as the character, the symbol, the one-character graphic is not stored in the video RAM of the display controller 116, no character is synthesized. Therefore, nothing is displayed on the screen of the display 102. When the operator waits for the customer to arrive at the POS terminal 100A and the customer comes, the bar code attached to the first product is read by the scanner 110, and the main body processing unit 114 stores the product file in itself. Referring to, the corresponding product name and price are read and registered in the internal RAM together with the product code, and the display position data and character size data (normal character size in this case) indicating the predetermined character position on the first line, Product code, product name,
Video RAM that outputs the price to the display controller 116 and is built in the display controller 116
, And then the receipt printer 106 to write 1
Print out the product code, product name, and price for each product.

When the bar code attached to the second product is read, the main body processing unit 114 similarly searches for the corresponding product name and price and registers it in the internal RAM.
The product code, product name, and price together with the display position data and the character size data indicating the predetermined character position on the second line are output to the display controller 116 and written in the video RAM, and the receipt printer 106 is used for one product. Print out the product code, product name, and price of. If there are remaining products, the same process is repeated. On the way, the main body processing unit 114 makes an inquiry to the management controller 200 via the premises line 30 when the corresponding code does not exist in the product file built in itself, and the management controller 200 makes the main body processing unit 21 of the controller main body 208.
2 refers to the product master file 202, reads the corresponding product name and price, and returns it to the terminal that issued the inquiry,
The main body processing unit 114 performs processing based on the returned information. The display controller 116 refers to the data in the built-in video RAM, reads the font from the character generator at a predetermined timing, and synthesizes the character with the input analog video signal for output. The character-synthesized analog video signal is output to the display 102 via the switch 158 and displayed on the screen. When only the POS operation image is displayed, the normal font size is used.
It becomes like (1). The center of the POS operation image coincides with the center of the screen viewed in the left-right direction.

When scanning of all products is completed and the operator presses the total key, the main body processing unit 114 calculates the total amount of this time, stores it in the RAM and outputs the total amount character to the display controller 102, and the customer When the total amount is displayed on the display 104 and the receipt printer 106 is used to print the amount, the customer makes a payment, presses the deposit input key, and then inputs the amount using the ten-key pad. The difference between the money and the total amount calculated above is calculated, registered in the RAM, the deposit money character and the difference character are output to the display controller 102, and the deposit money and fishing are displayed on the customer display 104 side by side with the total amount. The receipt printer 106 is used to print the deposit and fishing. The operator pays the change and gives the receipt. When the total key is pressed, the main body processing unit 1
The management controller 2 reads out all the purchased product information (product name, price, etc.) registered in the RAM this time and transmits it to the management controller 200 via the premises line 30.
The main body processing unit 208 of 00 is registered in the sales master file 204.

As described above, in the single display mode of the POS operation image, only the POS operation image is displayed on the screen, but until the next customer comes to the POS terminal 100A,
An operator does not leave the terminal, and the surveillance camera 40
When you want to monitor the images captured in A-40D by splitting them on the screen, press all camera keys. Then, the main body processing unit 114 instructs the image reading / conversion control unit 154 to perform divided reading of all cameras, and switches the switch 158 to the a side. The image reading / conversion control unit 154 uses the video RAM 1
Each of the digital images stored in 30 to 136 is vertically and horizontally compressed to 1/2, and the screen is divided into four. The compressed image from the video RAM 130 is the upper left of the screen, the video RA.
The compressed image from M132 is in the upper right corner of the screen, video RAM13
The compressed image from 4 is at the lower left of the screen and the compressed image from the video RAM 136 is at the lower right of the screen, and a digital image for one screen is created and output, and the video conversion unit 156 performs analog conversion and synchronization addition. Output to the display 102 via the switch 158. As a result, on the screen, as shown in FIG. 5B, the image captured by the monitoring camera 40A is in the upper left, the image captured by the monitoring camera 40B is in the upper right,
The video captured by surveillance camera 40C is in the lower left corner, surveillance camera 4
The video captured at 0D is divided and displayed in the lower right. As a result, the situation inside and outside the store can be grasped at once.

If, for example, there is a suspicious point in the image captured by the surveillance camera 40A and it is desired to display a large image on the screen, the camera A key is pressed. Then, the main body processing unit 114 instructs the image reading / conversion control unit 154 to perform the single reading of the camera A, and the switch 158 remains switched to the side a. The image reading / conversion control unit 154 uses the video RAM 13
The digital image stored in 0 is directly read and output. Therefore, on the screen, only the image captured by the monitoring camera 40A is displayed on the entire screen as shown in FIG. 6A, so that details can be seen well. When it is desired to display the images captured by the other surveillance cameras 40B to 40D in a large size, the camera B key to the camera D key may be pressed, and when the original split screen is desired to be restored, all camera keys may be pressed.

In this way, when the operator monitors the POS terminal 100A and there is a customer who has a purchased product, if he / she wants to continue monitoring, he / she presses the composite key and reads the bar code. When the composite key is pressed, the main body processing unit 114 switches the switch 158 to the b side. And every time the barcode is read,
In the same manner as described above, the display controller 116
The display position data and character size data (normal size), product code, product name, and price are output to the receipt printer 106, and the product code, product name, and price are printed out. Since the display controller 116 synthesizes characters and the like relating to the POS operation image with the analog video signal relating to the surveillance video output from the video converting unit 156 and then outputs to the display 120 via the switch 158, for example, on the screen, As shown in FIG. 6B, an image in which the POS operation image is superimposed on the surveillance video is displayed.
Therefore, the operator can proceed with the settlement work while monitoring the inside and outside of the store.

When the VTR 44 is to play back the surveillance video previously recorded and want to watch the video while waiting for the next customer or proceeding with the settlement work,
With the VTR 44 in the playback mode, the keyboard 10
Press the VTR key of 6. The video signal output from the VTR 44 is transmitted via the video line 460 to the POS terminal 100A.
Is input to the terminal main body 112 of the computer, converted into a digital image by the A / D converter 126 and the image drawing unit 150, and converted into the video
Written to AM 138. When the VTR key is pressed, the main body processing unit 114 reads the VTR independently and reads the image.

Along with the (reduced size), the product code, product name, price, etc. are output to the display controller 116, and if the settlement process is in progress, the video RAM of the display controller 116 is cleared once, and then the data already registered in the built-in RAM is displayed. By using the display position data and the character size data (reduced size) corresponding to the area on the right side of the screen, the product code, the product name, the price, etc. are output to the display controller 116. The display controller 116 combines the analog video signal input from the video conversion unit 156 with characters and the like so that the POS operation image is displayed on the right ⅓ of the screen, and outputs it to the display 102 via the switch 158. Therefore, the screen shown in FIG.
As shown in, the video captured by four surveillance cameras, VTR
44 playback images, still images from TV phones, and POS operation images will all be displayed, so that the operator can monitor inside and outside the store, check VTR images, and communicate by TV phone without having to move anywhere. , It becomes possible to perform the settlement work in parallel at the same time.

In the management controller 200 as well, by specifying various display modes for the display 210 with the keyboard 206, in the same manner as described above, in addition to the POS operation in the management controller 200, monitoring inside and outside the store and VTR image display are performed. It is possible to perform checking, communication by TV phone, and settlement work, but since it is almost the same as in the case of the POS terminal, detailed description is omitted.

The VTR 44 not only records and plays back the images captured by the surveillance camera, but also the training videos,
By playing back new product introduction videos, etc., more advanced usage becomes possible. In addition, NTS from the TV phone base unit and handset
Although the video signal converted into the C format is output and A / D converted to write the digital image in the video RAM, the original still image may be written in the video RAM as it is. Further, when a surveillance camera, VTR, or TV phone outputs a color video signal, the display of the POS terminal or the management controller is made to support analog R, G, B signals, and at the input stage of each video signal of the terminal body and the controller body, An RGB decoder is provided to decompose the R, G, and B primary color signals, and then each primary color signal is processed by the A / D converter and the subsequent processing of FIG. 3 and FIG. 4 to input from each video source device. Images can be displayed in color.
At this time, if a display controller is also provided for each R, G, B, the POS operation image can be displayed in color.
Further, since the image displayed on the monitor device can be viewed on the display of the POS terminal or the management controller, the monitor device is not always necessary, and if the monitor device is omitted, the installation space can be saved. Although the present invention has been described with reference to the embodiments, modified examples, and application examples, the present invention can be modified in various ways according to the gist of the present invention described in the claims, and the present invention does not exclude these. ..
