  It should be noted that not all apparatuses have these configurations, and it is only necessary to have necessary ones.

  Next, an example of the hardware configuration of the network camera 102 shown in FIG. 1 will be described with reference to FIG.

  In FIG. 3, the network camera 102 includes a so-called digital video camera or the like, and includes a photographing lens 301, an image sensor (hereinafter referred to as “CCD”) 302, and an analog-digital converter (hereinafter referred to as “ADC”) 303. , Image processor 304, controller 310, buffer memory 311, flash ROM 312 (storage means), interface circuit (hereinafter referred to as "I / F circuit") 313, card holder 314, memory card 315 (storage means), display driver 316, a USB driver 318, and an operation unit 320.

  The network camera 102 generates an image in response to pressing of the shooting button 323 (shutter button). In the present embodiment, the camera is configured to shoot when the shooting button 323 (shutter button) is pressed. However, there is no shooting button 323 (shutter button), and shooting is performed when a user gives a shooting instruction on the touch panel. It is also possible to do so.

  The lens 301 includes an objective lens, a zoom lens, a focus lens, and the like. The zoom lens and the focus lens are driven in the optical axis direction by a driving mechanism (not shown).

For example, the electronic zoom processing unit 307 can extract a center image of 1024 × 768 dots from a captured image of 1600 × 1200 dots and enlarge the image to a size of 1600 × 1200 dots while performing data interpolation.

  The compression unit 308 has a function of compressing image data by a compression format such as JPEG (Joint Photographic Expert Group). The decompression unit 309 has a function of decompressing compressed image data. For example, when compressing image data using the JPEG method, first, a discrete cosine transform process is performed (DCT process) that digitizes the ratio of high-frequency components and low-frequency components of image data. Next, a quantization process is performed for expressing the gradation or gradation of the image by a numerical value (quantization bit number). Finally, the image data is compressed by the Huffman encoding process. Specifically, the signal character string of the image data is segmented every certain bit, and a shorter code is given to a character string having a high appearance frequency. Note that the compression unit 308 and the decompression unit 309 can be omitted in the case of a method of recording image data without performing compression processing. Further, the image data compression format is not limited to the JPEG format, and the same processing can be performed even in a GIF (Graphical Interchange Format) format.

Note that the operation unit 320 includes operation buttons other than the illustrated operation buttons, but a description thereof will be omitted.

  The mode dial 322 is a rotatable dial for switching the mode of the photographing operation. The user can rotate the mode dial 322 to perform a plurality of shooting operations including an administrator mode and a shooting operation mode other than the administrator mode that can restrict access to image data stored in the memory card 315. It is possible to select a mode.

  The shooting operation mode other than the administrator mode is, for example, an Auto mode or a night scene mode in which shooting settings (white balance, shutter speed, etc.) held in advance by the network camera 102 are easily displayed to the user, or the user arbitrarily selects There is a manual mode in which shooting settings can be set.

  The browse button 326 is a button for switching to a browse mode (image reproduction mode) for browsing captured image data. When the browse button 326 is pressed, the shooting mode is changed to the browsing mode. Note that the method for switching to the viewing mode is not limited to pressing the viewing button 326, and may be a transition method using a touch panel (not shown) on the liquid crystal display 317.

  In the browsing mode, the controller 310 reads setting information and image data from the memory card 315 mounted on the card holder 314 via the I / F circuit 313. The setting information includes the number of images recorded on the currently installed memory card 315 and the capacity of the recorded image data. The read image data is, for example, image data or thumbnail data for one image. Note that the image data read from the memory card 315 is compressed in a predetermined compression format as described above.

  The image data read from the memory card 315 is input to the display driver 316 via the I / F circuit 313 and the controller 310. The display driver 316 displays the input image data on the liquid crystal display 317.

The cursor key 324 is a key for the user to perform a predetermined instruction or function selection to the photographing apparatus. The user can perform operation inputs such as various setting information and user authentication information for the network camera 102 with the cursor key 324. The cursor key 324 can display a menu screen on the liquid crystal display 317 and can select a predetermined function of the network camera 102.
Next, the moving image extraction process will be described with reference to FIG.

  Of the processes shown in the flowchart of FIG. 4, steps S401 to S403 are processes in which the CPU 201 of the cash register terminal 101 reads and executes a predetermined control program, and steps S404 to S406 are performed by the controller 310 of the network camera 102. The control program is read and executed.

  In step S401, the CPU 201 of the cashier terminal 101 performs an accounting process. Specifically, it is a process of reading the barcode attached to the product and acquiring the price of the product.

  In step S <b> 402, the CPU 201 of the cash register terminal 101 receives a receipt issuance instruction and issues a receipt when the accounting process for the last product is completed and the payment method is determined.

  At this time, information for identifying the accounting process relating to the receipt is printed on the receipt. Specifically, the identification information is described by an identification number, a barcode, a two-dimensional code, or the like.

  In step S <b> 403, the CPU 201 of the cash register terminal 101 transmits a notification that a receipt has been issued to the network camera 102.

  The notification transmitted here includes information such as the identification information described in the receipt, the accounting process end time in step S401, and the receipt issue time in step S402. The end time of the accounting process can be specified by the time when the accounting process of the last product (the latest accounting process retroactive from the time of receipt is issued) is performed.

  In step S404, the network camera 102 receives the notification transmitted from the cashier terminal 101 in step S403.

  In step S405, the network camera 102 extracts, from the moving images taken by the network camera 102, one moving image file from the end time of the accounting process received in step S404 to the time when the receipt is issued. Note that the network camera 102 always shoots moving images, and in step S405, the moving image to be recorded is extracted from the captured moving images.

  In the present embodiment, one movie file is extracted from the end time of the accounting process to the time when the receipt is issued, but it may be extracted as one movie file from the start time of the accounting process to the time when the receipt is issued.

  In step S406, the moving image file extracted in step S405 and the identification information received in step S404 are stored in association with each other. An example of data stored in association with each other is shown in FIG.

In the present embodiment, the video file and the identification information have been described as being stored in the network camera 102. However, the moving image file and the identification information may be stored in an external storage device that is communicably connected to the network camera 102.
And the process of this flowchart is complete | finished.

  In the present embodiment, the network camera 102 has been described to execute the moving image extraction and storage processing. However, the information processing apparatus (not shown) having a function of editing and analyzing the moving image shot by the network camera 102 has been described. It may be processed.

  Next, still image acquisition processing executed by the network camera 102 will be described with reference to FIG.

  In step S501, the network camera 102 acquires the moving image data stored in step S406.

  In step S502, the network camera 102 determines whether a predetermined still image acquisition condition is satisfied for the scene included in the moving image acquired in step S501.

  If the scene satisfies the predetermined condition (step S502: YES), the process proceeds to step S503.

  If the scene does not satisfy the predetermined condition (step S502: NO), the process proceeds to step S504.

  In step S503, the network camera 102 acquires and stores as a still image the scene determined to be a scene that satisfies the predetermined condition in step S502. At this time, the identification number associated with the moving image data is also stored in association with the scene. An example of data stored in association with each other is shown in FIG.

  In step S504, the network camera 102 determines whether the determination process in step S502 has been executed for all scenes of the moving image acquired in step S501.

  If the process has been executed for all scenes (step S504: YES), the process shown in this flowchart is terminated.

  If a scene that has not been processed remains (step S504: NO), the process proceeds to step S502.

  In the present embodiment, the network camera 102 has been described to execute the still image acquisition process. However, the processing is performed by an information processing apparatus (not shown) having a function of editing and analyzing a moving image shot by the network camera 102. May be.

  Further, a predetermined time before and after a scene that satisfies the condition may be left as a still image. For example, a process of acquiring still images at intervals of 1 second from 5 seconds before to 5 seconds after a scene that satisfies the conditions may be performed. By leaving a plurality of images as still images in this way, when a trouble or the like occurs, the context can be grasped by the still image, which can be used for troubleshooting.

  Here, the still image acquisition conditions in step S502 will be described with reference to FIGS.

  FIG. 9 is a diagram showing a state of money payment at the time of accounting. As shown in FIG. 9, it is assumed that the network camera 102 is photographing a region where money is placed (passed through) (for example, a tray for money exchange).

  FIG. 10 is a diagram for explaining still image acquisition conditions, and is an enlarged view of an area where money is placed in FIG. 9.

  As a still image acquisition condition, for example, it is a condition that money is reflected in a photographed image. In this case, money image data is registered in advance, the degree of similarity between the object shown in the photographed image and the registered money image data is calculated, and if the predetermined degree of similarity is satisfied, the object is selected. Judge that it is money and shoot a still image.

  It is also possible to make a determination based on the shape of the object shown in the photographed image. For example, it is possible to determine whether it is a banknote by determining whether it is a rectangular object. It is also possible to determine a banknote based on a condition such as whether or not the object has an edge (side) and a corner.

  Further, whether to acquire a still image may be determined based on whether an object moving in a predetermined direction is detected. For example, the example of FIG. 10 represents an image in a case where it is determined based on whether an object has passed through a predetermined detection line in a predetermined direction. More specifically, in FIG. 10, the determination is made based on whether or not a moving object (for example, a customer's hand or money) has passed from the bottom to the top (from the customer side to the clerk side).

  In this way, by detecting that the customer has made a payment based on whether or not the object has passed through a predetermined detection line, for example, payment by a credit card can be detected. Further, by determining whether the object has passed in a predetermined direction, it is possible to determine whether the store clerk's hand has passed, or the customer's hand, etc. That is, it is possible to determine whether an object has come out from the store clerk side or from the customer side.

  Next, the display processing of moving images and still images by the display terminal 103 and the network camera 102 will be described with reference to FIG.

  Of the processes shown in the flowchart of FIG. 6, steps S601, S602, S606, and S607 are processes in which the CPU 201 of the display terminal 103 reads out and executes a predetermined control program, and steps S603 to S605 are network cameras. 102 is a process to be executed.

  In step S601, the CPU 201 of the display terminal 103 acquires the identification information described in the receipt issued in step S402. For example, identification information is acquired by reading a barcode or a two-dimensional code.

  In step S <b> 602, the CPU 201 of the display terminal 103 transmits a moving image / still image acquisition request including the identification information acquired in step S <b> 601 to the network camera 102.

  In step S603, the network camera 102 receives the acquisition request including the identification information transmitted from the display terminal 103 in step S602.

  In step S604, the network camera 102 searches for the moving image / still image stored in association with the identification information based on the identification information included in the moving image / still image acquisition request received in step S603.

  In step S605, the network camera 102 transmits the moving image / still image searched in step S604 to the display terminal 103.

  In step S606, the CPU 201 of the display terminal 103 receives the moving image / still image transmitted from the network camera 102 in step S605.

  In step S607, the CPU 201 of the display terminal 103 displays the moving image / still image received in step S606 on the display unit. Then, the process shown in this flowchart is terminated.

  In the present embodiment, it has been described that moving images and still images are acquired from the network camera 102 and displayed on the display terminal on the assumption that moving images and still images are stored in the network camera 102. As described above, when moving image or still image data is stored in an external device, the processing subject in steps S603 to S605 is not the network camera 102, and the device storing the data or the device can be operated. It becomes a device.

  FIG. 8 is a diagram illustrating a state in which a moving image and a still image are displayed on the display terminal 103.

  In FIG. 8, a so-called smartphone or tablet terminal is assumed as the display terminal 103. The display terminal 103 may be a smartphone or a tablet terminal as shown in FIG. 8, or may be a personal computer (PC), a television, or any terminal that can display moving images and still images.

  In FIG. 8, a moving image and a still image are simultaneously displayed on one screen, but may be displayed separately. That is, a configuration may be used in which a moving image and a still image can be confirmed by switching a display for switching a display between a screen for reproducing a moving image and a screen for displaying a still image.

  As shown in FIG. 8, it is composed of a moving image playback area 801 and a still image display area 802.

  In the moving image reproduction area 801, the moving image shot by the network camera and stored in the data table of FIG. 12 is reproduced. In the still image display area 802, an image acquired as a scene satisfying the still image acquisition condition is displayed. As shown in the still image display area 802, a plurality of still images are displayed in time series. By displaying in this way, for example, when a trouble occurs, it is possible to grasp the front-rear relationship with a still image.

Also, the control bar 803 is provided, and the moving position of the moving image can be adjusted by operating the control bar 803 left and right.
<Second Embodiment>

  In the first embodiment, the process of creating a file and acquiring a still image of moving image data that has already been captured and saved by the network camera 102 has been described.

  In the second embodiment, a configuration in which the network camera 102 performs moving image shooting and data storage processing in response to processing in the cashier terminal 101 will be described.

  FIG. 7 is a flowchart illustrating processing executed by the network camera 102 according to the second embodiment.

  Of the processes shown in FIG. 7, steps S701 to S703 are processes in which the CPU 201 of the cashier terminal 101 reads and executes a predetermined control program, and steps S704 to S711 are performed by the controller 310 of the network camera 102. Is read and executed.

  First, the flow of processing in the cash register terminal 101 will be described.

  In step S701, the cashier terminal 101 performs an accounting process. The accounting process refers to a series of processes for reading a barcode attached to a product and accounting for the product.

  In step S702, the cashier terminal 101 issues a receipt for the accounting process in step S701.

In step S703, the cashier terminal 101 transmits information for identifying the accounting process in step S701 to the network camera 102.
And the process of this flowchart is complete | finished.
Next, processing in the network camera 102 will be described.

  In step S704, it is determined whether or not the accounting process at the cashier terminal 101 has been started.

  When the start of the accounting process at the cash register terminal 101 is detected (step S704: YES), the process proceeds to step S705.

  In step S705, the network camera 102 starts shooting a moving image.

  In step S706, the network camera 102 determines whether an event that satisfies a predetermined still image acquisition condition has occurred in the image being shot. A specific example of the still image acquisition condition is the same as that in step S502 in the first embodiment, and a description thereof will be omitted here.

  If an event that satisfies the still image acquisition condition occurs (step S706: YES), the process proceeds to step S707.

  If no event that satisfies the still image acquisition condition has occurred (step S706: NO), the process proceeds to step S708.

  In step S707, the network camera 102 captures a still image of the event determined to satisfy the condition in step S706. As for the still image acquisition in step S707, a plurality of still images may be acquired in a predetermined range before and after, similarly to step S503.

  In step S708, the network camera 102 determines whether a receipt issuance process has been performed at the cash register terminal 101.

  If receipt issuance by the cashier terminal 101 is detected (step S708: YES), the process proceeds to step S709.

  If receipt issuance by the cashier terminal 101 has not been detected (step S708: NO), the process proceeds to step S706.

  In step S709, the network camera 102 ends the moving image shooting process.

  That is, moving image shooting is continued until a receipt is issued by the cash register terminal 101. When an event that satisfies the still image acquisition condition occurs during moving image shooting, processing for shooting the event as a still image is performed. Then, when the receipt issuance by the cashier terminal 101 is detected, the moving image shooting is ended.

  In step S <b> 710, the network camera 102 acquires information for identifying the accounting process transmitted from the cashier terminal 101.

  In step S711, the network camera 102 associates the captured moving image data and the still image captured in step S707 with the identification information acquired in step S710 in the storage area of the network camera 102 or the storage area of the external device. Remember. An example of the data stored in association with each other is shown in FIG.

  In the present embodiment, it is determined whether or not the accounting process has been started in step S704. However, it is determined that the accounting process has ended (the accounting process for the last product has been performed), and video shooting is started (step S704). S705).

The moving image reproduction process is the same as that shown in the flowchart of FIG. 6 and the display screen of FIG.
The above is the processing content in the second embodiment of the present invention.

  FIG. 11 shows data in which an event that has occurred in the cash register terminal 101 is associated with an event occurrence date and time.

  Events that occurred in steps S401, S402, S701, S702, etc., and the occurrence date are registered in association with each other. For example, in the example shown in FIG. 11, the time when the accounting process is started (the first accounting process after the previous receipt issuance) and the end time of the accounting process (the accounting process for the last product (the accounting process immediately before the receipt issuance)) ) And the receipt issuance time are registered.

  In step S403, the event shown in FIG.

  FIG. 12 is an example of a data table in which a moving image file and a still image file captured by the network camera 102 are registered in association with identification information.

  For example, if the identification information indicating the accounting process in FIG. 11 (a process started at 10:15 on June 25, 2014 and issued at 10:17:30 on the same day) is “0001”, the process The moving image and still image according to are “0001.mp4” and “0001.jpg”.

  In other words, in the case of a configuration in which a moving image from the start of accounting processing to receipt issuance is stored, the moving image file “0001.mp4” is from June 25, 2014, 10:15:00 to 10:17:30. The video data is 2 minutes and 30 seconds.

  “0001.jpg” is still image data of a scene that satisfies the still image acquisition condition in the moving image data.

  As described above, on the basis of the receipt issuance timing at the cash register terminal, the video shot by the network camera 102 is divided, video data is created, and the video data and the accounting process by the cash register terminal are stored in association with each other. It becomes possible to make it easy to search which moving image is the moving image of which accounting process. In other words, the receipt issuance is a process that is performed after the accounting process is completed and the payment is made. Therefore, by separating at this timing, a series of accounting processes can be stored as one moving image.

  In addition, by storing the timing from the start or end of the accounting process at the cash register terminal to the receipt issuance as a single moving image file, it is possible to avoid storing unnecessary moving images and to reduce the capacity. .

  For example, in the example of FIG. 11, a receipt is issued at 10:22:40 on June 25, and the start of the next accounting process is 10:50:20. In this case, the time from 10:22:40 to 10:50:20 is a time when no processing is performed, and it is meaningless to leave a moving image of this time. Therefore, by executing the processing of the present invention, it is possible to leave only a moving image of a necessary time period without leaving a moving image of the useless time period, which can contribute to capacity reduction.

  In addition, by acquiring scenes that satisfy certain conditions from the captured videos as still images, the context can be grasped by the still images when trouble occurs, which can be useful for troubleshooting. Can do. At this time, by leaving the scenes before and after the scene satisfying the predetermined condition as still images, a series of flows can be grasped by the still images, which can be used for troubleshooting.

  In addition, the identification information is printed on a receipt issued from the cash register terminal, and the identification information and the moving image / still image are stored in association with each other, so that the accounting process related to the receipt is based on the identification information described in the receipt. It is possible to efficiently search for moving images and still images.

  It should be noted that the configuration and contents of the various data described above are not limited to this, and it goes without saying that the various data and configurations are configured according to the application and purpose.
