Description

  The present invention relates to a search system for an image obtained by photographing a store.

  In various stores such as convenience stores, supermarkets, restaurants, electronics stores, etc., merchandise accounting processing, dining fee accounting processing, etc. are performed using the POS terminal. Customers who purchase products go to the cash register with a basket of products. Then, the product basket is placed at the cashier counter and waits for a cashier operation by the store clerk. Or the customer who finished eating and drinking goes to a cash register with a slip. Then, it waits for the cashier operation by the store clerk.

  The store clerk performs an input operation on the POS terminal while operating the products in the product basket one by one. Recently, most POS terminals are equipped with bar code readers, making cashier operation simple. Alternatively, the store clerk inputs the food and drink price into the POS terminal while referring to the handwritten or printed slip.

  When the store clerk finishes the input operation to the POS terminal, the customer pays the price. The store clerk stores the money in the POS terminal drawer. When change is necessary, the cash is taken out from the drawer and returned to the customer.

  The accounting process is performed by the series of operations as described above. During this time, information input to the POS terminal is accumulated as journal data. The journal data stores information such as when and how many products were sold, how much the total amount was, and how much change was returned.

  As described above, the POS terminal stores journal data. By referring to this data, the past transaction history can be known. In addition, by leaving the journal data, it is possible to specify the location where a mistake has occurred later even if an erroneous registration operation is performed. It is also possible to prevent unauthorized transactions to some extent.

  However, there are fraudulent transactions that cannot be identified by referring only to journal data. For example, it is assumed that a store clerk receives only cash from a customer without performing an input operation on a POS terminal for a product. Even if the cashier does not store the cash in the POS terminal, no record is left in the journal data.

{First embodiment}
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an overall view of a system that performs image capturing, recording, and searching. The first embodiment is a system used at a cash register such as a convenience store. The cashier counter 40 is provided with a POS terminal 10. The POS terminal 10 is a device that processes and records purchase transactions, and includes an input unit 12 composed of various keys, and a display 11 that displays details of operations performed by the input unit 12, the total amount, and the like. The input unit 12 includes a bar code reader (not shown). In the present embodiment, the POS terminal 10 has a function as a register.

  The store clerk 41 performs a cash register operation or the like inside the cash register counter 40. The customer 42 places the product 43 to be purchased on the cashier counter 40. Here, the position where the customer 42 places the product 43 is limited to some extent from the position of the POS terminal 10 or the like. An area where the product 43 is placed is illustrated as an area 44.

  Cameras 1 and 2 are installed above or beside the cashier counter 40. The angle of the camera 1 is fixed so as to photograph the POS terminal 10. In particular, the camera 1 is set so that the input unit 11 of the POS terminal 10 and a place where cash is taken in and out are photographed. In many cases, since a drawer (safe) is provided on the lower side of the POS terminal 10, the camera 1 is installed so that cash can be taken in and out of the drawer.

  The angle of the camera 2 is fixed so that an area including the clerk 41 and the customer 42 is photographed around the area 44 where the product 43 is placed. The area 44 includes an area where the store clerk 41 performs an operation of reading the barcode of the product 43 by using, for example, a barcode reader.

  Image data taken by the cameras 1 and 2 is transmitted to the photo journal recorder 20 in real time via a cable. In addition, the POS terminal 10 and the photo journal recorder 20 are connected via the LAN 6, and the POS terminal 10 and the photo journal recorder 20 can transmit and receive data via a network.

  FIG. 2 is a functional block diagram of the POS terminal 10 and the photojournal recorder 20. When information on the product 43 to be purchased is input in the input unit 12 including various keys and a barcode reader, the information is displayed on the display 11 and the control unit 13 executes sales accounting processing. . Sales accounting processing includes calculation of the total sales amount, calculation of change, and the like. Moreover, the control part 13 accumulate | stores the journal data JD which is transaction history data in a memory | storage device. When all the accounts for a certain customer are completed, a receipt is output from an output unit (not shown) based on the journal data JD. The stored journal data JD is transmitted to the photo journal recorder 20 via the communication unit 14 in real time.

  Information regarding all operations performed using the input unit 12 is stored in the storage device as operation history data PD. The operation history data PD is a record in which all operation contents are sequentially recorded together with operation time information every time various keys are selected or each time a reading operation is performed by a barcode reader. Therefore, once an operation is performed, the operation history data PD is always recorded even if a cancel operation is performed. The stored operation history data PD is transmitted to the photo journal recorder 20 via the communication unit 14 in real time.

  The recording instruction unit 15 is a functional unit that monitors the operation input in the input unit 12 and instructs the recording timing of the image data. When any input operation is performed by the input unit 12 in a state where the image data recording operation is not performed, the recording instruction unit 15 sends an image to the photojournal recorder 20 via the communication unit 14. Send recording start information. On the other hand, after a predetermined input operation has been performed, the recording instruction unit 15 transmits image recording end information to the photojournal recorder 20 via the communication unit 14 after a predetermined time has elapsed. For example, after the “total” key is selected at the end of the cash register operation, the end information is transmitted 30 seconds later.

  The photojournal recorder 20 receives image data output from the cameras 1 and 2 by the image input unit 21. The received image data is compressed in the image processing unit 22 and stored in the memory 25. The memory 25 can store image data of a predetermined number of frames received from the image processing unit 22. For example, the memory 25 stores from the image data (image frame) 10 seconds ago to the latest image data (image frame).

  When the image recording process is performed by the recording unit 24, the image data stored in the memory 25 is sequentially stored as image data VD in the storage device 5. The recording unit 24 performs image recording start and stop control based on the image recording start information and end information received from the POS terminal 10.

  As a first method, the recording unit 24 starts recording the image data VD from the time when the start information is received, and ends the recording of the image data VD when the end information is received. As a second method, the recording unit 24 starts recording the image data VD from a time point that is a predetermined time after receiving the start information, and ends recording the image data VD when the end information is received. The recording unit 24 can record images retroactively by the amount of image data stored in the memory 25. For example, when image data for 10 seconds is buffered in the memory 25, recording of image data can be started retroactively 10 seconds ago. As described above, according to the first method, since the image is recorded only during the registration operation, it is possible to save the storage area without recording the unnecessary image data VD. According to the second method, recording is started retroactively while saving the storage area, so it is possible to check the state immediately before the registration operation.

  Further, as described above, the image recording end information is transmitted after a predetermined time has elapsed after a predetermined input operation has been performed. Therefore, after the cash register operation is completed, the image data VD is recorded even when cash is being transferred between the store clerk 41 and the customer 42. Therefore, a part of the entire accounting operation is accumulated as an image. It is possible.

  Here, among the image data VD stored in the storage device 5, the image data VD received from the camera 1 is referred to as registration image data VD1, and the image data VD received from the camera 2 is referred to as counter image data VD2.

  In the present embodiment, the storage device 5 is a removable medium that can be attached to and detached from the photojournal recorder 20. As the storage device 5, for example, a compact flash (R) can be used.

  As described above, the journal data JD and the operation history data PD are transmitted from the POS terminal 10. The recording unit 24 sequentially records the journal data JD and the operation history data PD received via the communication unit 23 in the storage device 5.

  In this manner, the registration device image data VD1 photographed by the camera 1, the counter image data VD2 photographed by the camera 2, and the transaction history processed in the POS terminal 10 are recorded in the storage device 5 of the photo journal recorder 20. Journal data JD and operation history data PD in which all operation histories performed at the POS terminal 10 are recorded are accumulated.

  Next, the contents of each data will be described. FIG. 3 is a diagram schematically showing the contents of the image data VD. The format of the image data VD shown in this figure is common to the registration image data VD1 and the counter image data VD2. The image data VD is an image frame acquired at each time, and each image data VD includes a header part HP and a data part DP. The header portion HP includes time information when the image data VD is captured.

  FIG. 4 is a diagram showing the contents of the journal data JD. As shown in the figure, the journal data JD includes information on a plurality of items. "Transaction No information" is a number assigned for each transaction unit. This transaction unit is a unit in which a receipt is issued. “Transaction date / time information” is information indicating the date and time when the transaction was performed. The “product-specific transaction information” further includes a plurality of pieces of information. “Product-specific transaction information” includes information indicating the product number of the sold product, the number of products sold, the total price for each product sold, and the like. The “clearing information” includes the total amount of all sales items, information indicating the received cash, and the amount of change. “Registration information” includes information for identifying a cash register when a plurality of cash registers are installed, an identification number of the clerk 41 who performed the cash register operation, a name of the clerk 41 who performed the cash register operation, and the like. . “Customer information” is information including the age range, sex, and the like of the customer 42 who made the purchase.

  FIG. 5 is a diagram showing the contents of the operation history data PD. The operation history data PD includes “operation date / time information” indicating the year and month when the operation was performed, and “operation key information” indicating the type of the key on which the operation was performed. Further, the operation by the bar code reader is also recorded as “operation key information”.

  In the storage device 5 of the photo journal recorder 20, the image data VD, the journal data JD, and the operation history data PD as described above are recorded. These data are associated with each other based on time information. That is, in the image data VD, “shooting time information” is recorded in the header part HP, “transaction date information” is recorded in the journal data JD, and “operation date information” is stored in the operation history data PD. It is because is recorded. Therefore, by using the storage device 5 as a database, the image data VD, journal data JD, and operation history data PD can be mutually searched. For example, searching image data VD photographed in the same time zone based on operation history data PD, or retrieving image data VD photographed in the same time zone based on journal data JD (transaction history information). Etc. are possible.

  As described above, the data VD, JD, and PD stored in the storage device 5 are transferred from the cameras 1 and 2 to the photo journal recorder 20 in real time, or from the POS terminal 10 in real time. Forwarded to And since the image compression processing and the like are also executed in the photojournal recorder 20, the processing load on the POS terminal 10 is reduced. Therefore, when the POS terminal 10 performs the accounting process during the business hours of the store, the processing load on the POS terminal 10 does not increase due to the database creation process or the like.

  Next, a search process using data stored in the storage device 5 will be described. FIG. 6 is a functional block diagram of the search terminal 30 that performs search processing. Here, the POS terminal 10 or the computer 7 or the computer 9 shown in FIG. 2 can operate as the search terminal 30. Therefore, FIG. 3 shows common functional units necessary for the POS terminal 10 or the computers 7 and 8 to operate as search terminals. The computer 7 is connected to the photo journal recorder 20 via the LAN 6, and the computer 9 is connected to the photo journal recorder 20 via the LAN 6 and another network 8 (including a wide area network such as the Internet). Yes.

  When the POS terminal 10 also serves as the search terminal 30, it is not necessary to prepare a separate search terminal, and the POS terminal 10 can be used as the search terminal 30 after business hours have ended. In addition, the computer 9 can be used as a search terminal in a headquarters monitoring center located at a remote place away from the store.

  The search terminal 30 includes a display 31, an input unit 32, a search processing unit 33, a card I / F 34, and a communication unit 35. The input unit 32 includes various keys and a mouse. When various search processing instructions are performed by operating the input unit 32, the search processing unit 33 accesses the storage device 5 inserted into the card slot via the card I / F 34 and executes the search processing. Alternatively, the search processing unit 33 accesses the storage device 5 inserted in the photo journal recorder 20 via the communication unit 35 and executes the search process. In addition, the search processing unit 33 has a function of outputting search results to the display 31 and a function of outputting various search screens to the display 31.

  Therefore, when the POS terminal 10 also serves as the search terminal 30, the operator can execute the search process by operating the input unit 12 of the POS terminal 10. The search screen and search results are displayed on the display 11 of the POS terminal 10.

  FIG. 7 is a diagram illustrating an example of the search screen 50 displayed on the display 31 of the search terminal 30. As shown in the figure, the operator can search by specifying “transaction No.”, “transaction date / time”, “store clerk No”, “product name”, “cash type”, “cash register No”, etc. Can be performed. Here, “transaction No” is designated with No given for each transaction. In the “transaction date and time”, the date and time when the transaction was performed are specified. In “Clerk No”, a number, a symbol, or the like given in advance to the clerk in charge of the cash register is designated. The “product name” may be a form in which an actual product name is designated or a form in which a product number is designated. “Cash type” designates the type of cash paid by the customer (thousand-yen bill, 5,000-yen bill, 10,000-yen bill, etc.). In “Register No.”, a number, a symbol, and the like for identifying each POS terminal among the plurality of POS terminals installed in the store are designated.

  Here, the search conditions “transaction No.”, “transaction date / time”, “store clerk No”, “product name”, and “registration No” are input with information corresponding to the journal data JD. The corresponding information can be searched by searching for. On the other hand, information corresponding to the operation history data PD is input to the “cash type” that is the search condition. That is, the cash type is recorded in the operation history data PD by performing a key operation (such as a thousand yen bill key) corresponding to each cash type.

  When a search condition is input to the search screen 50 and a search instruction is issued, a search result screen 60 as shown in FIG. 8 is displayed. As shown in the figure, a transaction number is displayed at the top of the search result screen 60 so that the current display content is clear. Images captured by the cameras 1 and 2 are displayed in the image display areas 61 and 62, respectively. That is, the registration image data VD1 is displayed in the image display area 61, and the counter image data VD2 is displayed in the image display area 62.

  In the receipt display area 63, a receipt image created based on the journal data JD is displayed. In the receipt display area 63, the journal data JD may be displayed without being processed as it is, but as shown in the figure, the confirmation operation can be easily performed by matching the display layout of the journal data JD with the layout of the receipt. I am doing so. In the receipt image shown in the figure, “Transaction No. 123456789” corresponds to “Transaction No. Information” in the journal data JD, and “June 4, 2003 (Wednesday) 09:18” "Apple 012 × 1 250 Milk ..." corresponds to "Transaction information by product", "Subtotal ... Fishing ¥ 215" corresponds to "Clearing information", and "Register No13 Person in charge: 376 Tanaka "corresponds to" Register information ". In this figure, customer information is not displayed, but the number of customers, gender, and the like may be displayed.

  In the operation history display area 64, operation history data PD is displayed. The operation history display area 64 includes display areas 641 and 642. The display area 641 displays “operation date / time information” of the operation history data PD, and the display area 642 displays “operation key information” of the operation history data PD. Is displayed.

  The image data VD1, image data VD2, journal data JD, and operation history data PD displayed on the search result screen 60 are associated with each other by shooting time information, transaction date information, and operation date information, respectively. . Therefore, the camera image when the displayed receipt image is issued is displayed and the contents of the key operation performed at that time are displayed.

  Further, an image operation menu 65 is arranged on the search result screen 60. Using this operation menu, operations such as playback, fast forward, reverse playback, rewind, stop, pause, etc., of the images displayed in the image display areas 61 and 62 can be performed. For example, if it is possible to cue an image on a transaction basis, it is convenient when referring to an image from the start of the transaction.

  Further, the search result screen 60 also has a function as a search screen. First, the operator can select any one of the operation histories displayed in the operation history display area 64. This operation is performed using a keyboard and a mouse. In FIG. 8, the shaded portion indicates a state in which one of the operation histories is selected. In response to this operation, the search processing unit 33 executes search processing, acquires image data VD1, VD2 and journal data JD in the same time zone, and reflects the results on the search result screen 60. In this way, the image data VD1, VD2 and journal data JD can be searched from the operation history data PD.

  In the receipt display area 63, the journal data JD is displayed so as to be scrollable up and down in the order of transaction numbers. Therefore, the operator can change the displayed journal data JD to the previous and subsequent transaction Nos by performing an up / down scroll operation. In response to this operation, the search processing unit 33 executes search processing, acquires image data VD1, VD2 and operation history data PD in the same time zone, and reflects the results on the search result screen 60. In this way, the image data VD1, VD2 and operation history data PD can be searched from the journal data JD.

  As described above, according to the present embodiment, the image data VD, the journal data JD, and the operation history data PD are associated with each other by the time information and the search is performed, so that images and transaction information in the same time zone can be listed. It is possible and convenient.

  The operation history data PD is recorded only when the operation is performed, but the image data VD is continuously recorded from the beginning to the end of the transaction unit in the cash register. It is also possible to refer to an image while no key operation is being performed, such as during a cash exchange or during cash delivery.

{Second Embodiment}
Next, a second embodiment of the present invention will be described with reference to FIGS. Note that description of functions and processes similar to those of the first embodiment will be omitted, and description will be made with a focus on the features of the second embodiment.

  The second embodiment is a system used in a store such as a restaurant. In the restaurant, unlike the first embodiment, the customer 42 does not come to the cashier counter 40 with a product. At the restaurant, the customer 42 who has finished the meal comes to the cashier 40 with a handwritten or printed slip 45.

  In this embodiment, a camera 3 for photographing the slip 45 is installed. Similarly to the camera 1, the camera 3 is connected to the photo journal recorder 20 via a cable so that images taken by the camera 3 are transferred to the photo journal recorder 20 in real time.

  As shown in FIG. 10, the functional configuration of the POS terminal 10 and the functional configuration of the photojournal recorder 20 are the same as those in the first embodiment. However, the slip image data VD3 is stored in the storage device 5 as the image data VD captured by the camera 3. Therefore, the image captured by the camera 3 is also stored as the slip image data VD3 by performing the same processing as in the first embodiment. The format of the slip image data VD3 is the same as that shown in FIG.

  In this way, the registration image data VD1, the slip image data VD3, the journal data JD, and the operation history data PD are accumulated in a state where they can be associated with each other by time information. Various search processes can be executed using this database.

  FIG. 11 is a diagram showing the search result screen 70. In the image display area 71, a captured image of the camera 1 is displayed. In the image display area 72, an image of the slip 45 taken by the camera 3 is displayed. In the receipt display area 73, a receipt image generated based on the journal data JD is displayed. The operation history display area 74 is composed of display areas 741 and 742, the “operation date / time information” of the operation history data PD is displayed in the display area 741, and “operation key information” is displayed in the display area 742. . The contents of the image operation menu 75 are the same as those of the image operation menu 65 shown in FIG. The times of the image data VD1, VD3, the journal data JD, and the operation history data PD are associated with each other, that is, the images, receipt images, and operation histories of the same time zone are displayed. It is possible to list and compare information. In the same manner as in the first embodiment, various search processes can be executed to refer to a desired image, journal data JD, and operation history data PD.

  In particular, in this embodiment, since the slip 45 is photographed by the camera 3, it is possible to easily collate the contents of the slip 45 with the journal data JD and the operation history data PD. For example, an input error or the like can be easily found by comparing the image of the slip 45 with the journal data JD.

{Modifications}
In the first or second embodiment, two cameras are installed and images taken by the two cameras are stored. However, cameras that shoot other areas are added and added. Images taken by the camera may also be accumulated. Also in this case, similarly, it is possible to associate with the journal data JD and the operation history data PD by the photographing time information. Or the form which installs only one camera may be sufficient. For example, only a camera for photographing the POS terminal 10 may be installed, and only the registration image data VD1 may be stored as a database.

  Further, in each of the above embodiments, the case where there is one register counter 40 has been described as an example. However, the present invention can be applied even when a plurality of register counters 40 are installed and a plurality of POS terminals 10 are operating. It is possible to apply. In this case, journal data JD and operation history data PD regarding all the registries and image data VD regarding all the registries may be stored in one photo journal recorder 20, but a plurality of photo journal recorders 20 are prepared. Then, it may be distributed and accumulated.

  In each of the above embodiments, the POS terminal 10 starts the recording process in the photojournal recorder 20 triggered by the key operation, but a human body detection sensor is provided around the POS terminal 10, When the clerk 41 approaches the vicinity of the POS terminal 10 and the human body detection sensor detects the human body, the start information of the image recording may be transmitted. Then, when the store clerk 41 moves away from the POS terminal 10 and the human body detection sensor no longer detects the human body, the image recording end information may be transmitted.

  Also in this case, the image data VD is accumulated retroactively from the time when the photojournal recorder 20 receives the start information, so that the image can be referred to for a time zone just before the clerk 41 approaches the POS terminal 10. Is possible. Further, by accumulating the image data VD until a predetermined time elapses after receiving the end information, it is possible to grasp the situation after the clerk 41 leaves the POS terminal 10.
