  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an outline of use of the terminal device 10.

  The terminal device 10 according to the present invention is an electronic device such as a camera, a smartphone, a mobile phone, a PC (Personal Computer), a PDA (Personal Digital Assistant) having a function of capturing a still image or a moving image. The NFC card 20 is a card provided with an NFC tag 21 compliant with the NFC standard.

  In recent years, NFC cards equipped with NFC tags have rapidly spread, and are used, for example, as traffic cards for passing through automatic ticket gates, card-type electronic money, credit cards, employee ID cards, and the like. The NFC tag 21 is classified into NFC-A, NFC-B, NFC-F, NFC-V, and the like according to the communication technology to which each is applied. NFC-A is compliant with NFCIP-1, ISO / IEC18092, NFCIP-2, ISO / IEC21481, ISO14443 TypeA, or the like. NFC-B conforms to NFCIP-2, ISO / IEC21481, ISO14443 TypeB, or the like. NFC-F conforms to NFCIP-1, ISO / IEC18092, NFCIP-2, ISO / IEC21481, JISX6319-4, or the like. NFC-V is based on NFCIP-2, ISO / IEC21481, ISO15693, or the like. In the present embodiment, the terminal device 10 recognizes any type of NFC card 20.

  When the NFC card 20 is held over the terminal device 10, imaging is started in the terminal device 10. Since the user can acquire an image by holding the NFC card 20 over the terminal device 10 at a timing when the user wants to start imaging, it is not necessary to perform a touch operation to instruct the imaging timing to the terminal device 10. Accordingly, it is possible to prevent a phenomenon in which the terminal device 10 moves during a touch operation and is out of focus.

  FIG. 2 is a hardware configuration diagram of the terminal device 10. Hereinafter, the device configuration of the terminal device 10 will be described. In the following description, components necessary for describing the present invention are shown for convenience.

  The terminal device 10 includes a CPU 11, an NFC antenna 12, a flash memory 13, a camera unit 14, and a display 15, and each unit is connected by a bus. The CPU 11 is a central processing unit and executes processing according to a program stored in the flash memory 13. The NFC antenna 12 transmits and receives radio waves to and from the NFC tag 21.

  The flash memory 13 is a nonvolatile memory and stores a program executed by the terminal device 10. The camera unit 14 acquires video captured by an imaging device using a sensor such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor) as digital data and records it in the flash memory 13. The display 15 is a liquid crystal display that displays a GUI (Graphical User Interface) or the like, or an organic EL (Electro Luminescence).

  When the terminal device 10 receives an imaging instruction from the user, an image output from the camera unit 14 is displayed on the display 15. The NFC antenna 12 transmits inquiry radio waves to the surroundings, and when the NFC tag 21 is presented within a certain distance from the NFC antenna 12, a response from the NFC tag 21 to the inquiry is received. The video on the display 15 at the received timing is replaced with a predetermined format and stored in the flash memory 13. Thereafter, the fact that the video is stored in the flash memory 13 is displayed on the display 15.

  In addition, when the terminal device 10 receives a search instruction from the user and the NFC tag 21 is presented to the NFC antenna 12, the terminal device 10 determines whether the NFC tag 21 includes a unique ID that is a unique identification number of the NFC tag 21. Read attribute information. The CPU 11 reads out the video having information corresponding to the attribute information of the NFC tag 21 from the video stored in the flash memory 13 or the video recorded in an external server (not shown), and displays the video on the display 15.

  FIG. 3 is a functional block diagram of the terminal device 10. The function of the terminal device 10 will be described. In the following, constituent elements necessary for explaining the present invention are shown.

  The terminal device 10 includes a control unit 100 and a storage unit 107. The control unit 100 executes control related to video acquisition of the terminal device 10 by the CPU 11. The storage unit 107 has its function realized by the flash memory 13 or the RAM (not shown), and stores video captured by the camera unit 14 and also stores video for synthesis for performing synthesis processing described later.

  The control unit 100 includes a tag detection unit 101, an imaging unit 102, a video recording processing unit 103, an information acquisition unit 104, a video acquisition unit 105, and a distribution request unit 106.

  The tag detection unit 101 detects the approach of the NFC tag 21 when the NFC tag 21 approaches within a certain distance from the NFC antenna 12. The certain distance is a distance at which the NFC antenna 12 can receive a response radio wave from the NFC tag 21. Hereinafter, detection of the NFC tag 21 of the tag detection unit 101 refers to detection of the approach of the NFC tag 21 by the tag detection unit 101.

  The imaging unit 102 uses the camera unit 14 to control video acquisition. The video recording processing unit 103 performs predetermined processing on the video captured by the imaging unit 102 and stores the video in the storage unit 107. The information acquisition unit 104 acquires attribute information from the NFC tag 21 via the NFC antenna 12.

  The video acquisition unit 105 acquires the video stored in the storage unit 107 based on the information acquired from the NFC tag 21 by the information acquisition unit 104. Further, the video acquisition unit 105 acquires a video from a predetermined server connected via a network based on the information acquired from the NFC tag 21 by the information acquisition unit 104. When the terminal device 10 acquires a video from a predetermined server, the distribution request unit 106 requests the server to distribute the video.

  In imaging, when the NFC card 20 is presented within a certain distance from the terminal device 10, the tag detection unit 101 detects the NFC tag 21 included in the NFC card 20. When the tag detection unit 101 detects the NFC tag 21, the imaging unit 102 performs imaging. Further, when the NFC tag 21 is detected by the tag detection unit 101, the information acquisition unit 104 analyzes information output from the NFC tag 21 and acquires attribute information of the NFC tag 21.

  The video recording processing unit 103 embeds the attribute information of the NFC tag 21 acquired by the information acquisition unit 104 in Exif information that is meta information of the video captured by the imaging unit 102 and stores the video in the storage unit 107. . Video meta-information can be said to be video-related information. The terminal device 10 can store the acquired video in a server connected to the outside and set in advance. In this case, the video recording processing unit 103 stores the video in which the attribute information is embedded in the Exif information in the set server.

  In the search on the terminal device 10, when the NFC card 20 is presented within a certain distance from the terminal device 10, the tag detection unit 101 detects the NFC tag 21, and the information acquisition unit 104 displays the attribute information of the NFC tag 21. read. The video acquisition unit 105 reads from the storage unit 107 video data in which the attribute information of the NFC tag 21 read by the information acquisition unit 104 is recorded in the Exif information.

  In the search on the server, the distribution request unit 106 creates a URL for specifying video data from an external server based on the attribute information of the NFC tag 21 acquired by the information acquisition unit 104. The distribution request unit 106 transmits an HTTP request specifying the created URL to the server. The server that has received the HTTP request generates a web page that is screen information for displaying a video having the attribute information of the NFC tag 21 in the Exif information, and transmits the web page to the terminal device 10. The terminal device 10 displays the received screen information on the display 15 using a Web browser or the like.

  With this configuration, the user can give an imaging start command to the terminal device 10 without touching the terminal device 10 by presenting the NFC tag 21 to the terminal device 10. The video imaged by the presentation of the NFC tag 21 is read from the terminal device 10 or the external server by holding the same NFC tag 21 over the terminal device 10 and displayed on the terminal device 10.

  (Procedure for imaging)

    FIG. 4 is a flowchart showing the imaging process.

  First, an imaging function is activated in the terminal device 10, and a screen output from the camera unit 14 is displayed on the display 15. The screen output from the camera unit 14 is, for example, a live view screen. When the NFC tag 21 is presented to the terminal device 10 and the tag detection unit 101 detects the NFC tag 21, the imaging process is started.

  First, the information acquisition unit 104 receives tag information from the NFC tag 21 (step S101). Specifically, the information acquisition unit 104 acquires tag information held by the NFC tag 21 from the NFC tag 21. The tag information is attribute information of the NFC tag 21.

  Here, the tag information that the information acquisition unit 104 acquires from the NFC tag 21 includes (i) a unique manufacturing number of the NFC tag 21, (ii) information indicating the technical method of the NFC tag 21, and (iii) an issuer of the NFC card 20 The event number or the like arbitrarily embedded in the NFC tag 21 by the service provider.

  (I) The manufacturing unique number of the NFC tag 21 is a unique number uniquely determined for the NFC tag 21 or a so-called one-time ID from which a different value is read each time the NFC tag 21 is read. Whether the unique number is held as attribute information or the one-time ID is generated every time it is read differs depending on the technical method of the NFC tag 21, but the information acquisition unit 104 acquires either of these. Hereinafter, the unique number or one-time ID read from the NFC tag 21 will be described as the unique ID.

  (Ii) Although the technical system of the NFC tag 21 has been described above, the NFC tag 21 is classified into NFC-A, NFC-B, NFC-F, NFC-V, and the like according to the communication technology. The information indicating the technical system of the NFC tag 21 is information indicating which technical system the NFC tag 21 complies with.

  (Iii) The event number is information for identifying an event. For example, in an event such as an exhibition, the event organizer can embed a number arbitrarily determined as event specifying information in the NFC tag 21 attached to the NFC card 20 distributed at the event. Since the NFC tag 21 has a memory area that can be freely used, a number determined as event specifying information is embedded in the memory area.

  In step S <b> 101, when the event specifying information is recorded on the NFC tag 21, the information acquisition unit 104 acquires the event specifying information from the NFC tag 21. Hereinafter, the event specifying information will be described as an event number.

  In step S101, (i) acquisition of the unique ID of the NFC tag 21 is indispensable, but (ii) information indicating the technical method of the NFC tag 21 and (iii) event number are the NFC tag 21 Acquired when it has information.

  The imaging function in the terminal device 10 has a self-timer function.

  Next, the imaging unit 102 determines whether or not the self-timer function is set to ON (step S102). If the self-timer setting is set to ON (when ON in step S102), the imaging unit 102 advances the process to step S103.

  The imaging unit 102 waits for a predetermined time set by the user after the tag detection unit 101 detects the NFC tag 21 (step S103).

  If the imaging unit 102 determines that the self-timer setting is not performed in the imaging function (in the case of OFF in step S102), or if the self-timer is set and waits for a predetermined time, the process proceeds to step S104. Proceed.

  The imaging unit 102 captures the video output from the camera unit 14 as a still image (step S104). For convenience, the information acquisition unit 104 performs capture in the step after acquiring tag information, but the order of processing is not limited to this. Since the acquisition of tag information by the information acquisition unit 104 and the capture by the imaging unit 102 are performed independently, as a result, the acquisition of tag information and the capture of video by the information acquisition unit 104 may be performed earlier.

  Next, the video recording processing unit 103 determines whether or not a video composition setting has been made in advance in the imaging function (step S105). The video recording processing unit 103 determines that the video composition setting has been made when the video composition setting flag is set to ON. When the video composition setting has been made in advance (when ON in step S105), a video composition process is performed (step S106). The video composition process will be described in detail later. If the video composition setting has not been performed in advance in the imaging function (when OFF in step S105), or the video composition processing has ended, the video recording processing unit 103 advances the processing to step S107.

  The video recording processing unit 103 adds the hash value of the tag information (unique ID) to the Exif information of the video to be processed (Step S107). Specifically, the information acquisition unit 104 calculates a hash value for the acquired unique ID of the NFC tag 21 using an arbitrarily set hash function. The video recording processing unit 103 embeds the hash value of the unique ID calculated by the information acquisition unit 104 in the Exif information of the video captured by the imaging unit 102 or the video that has undergone the video synthesis processing in step S106.

  Next, the video recording processing unit 103 determines whether there is an event number in the tag information (step S108). If the attribute information acquired by the information acquisition unit 104 from the NFC tag 21 is (iii) an event number (Yes in step S108), the video recording processing unit 103 advances the process to step S109.

  The video recording processing unit 103 adds an event number to the video Exif information (step S109). Specifically, the video recording processing unit 103 embeds an event number in addition to the Exif information in which the hash value of the unique ID is embedded. If there is no event number in the attribute information acquired by the information acquisition unit 104 from the NFC tag 21 (No in step S108), the video recording processing unit 103 proceeds to step S110.

  The video recording processing unit 103 stores the video in the storage unit 107 (step S110). Specifically, the video recording processing unit 103 stores the video data in which the attribute information of the NFC tag 21 is recorded in the Exif information in the storage unit 107, and ends the processing.

  Note that the video recording processing unit 103 may embed information specifying the technical method of the NFC tag 21 in the Exif information of the video. Information acquired from the NFC tag 21 such as the hash value of the unique ID, the event number, and information specifying the technical method of the NFC tag 21 and embedded in the video Exif information can be said to be related information.

  Note that the video recording processing unit 103 may store the video data in which the attribute information acquired from the NFC tag 21 is recorded in the Exif information in an arbitrary directory set by the user in the storage unit 107.

  Further, the video recording processing unit 103 may create a directory in the storage unit 107 for each attribute information of the NFC tag 21, and classify and store the video data. For example, the video recording processing unit 103 creates a directory for each of NFC-A, NFC-B, NFC-F, and NFC-V, which are the technical methods of the NFC tag 21, and changes the technical method of the NFC tag 21 acquired at the time of imaging. The video may be stored in a corresponding directory according to the specified information.

  Further, the video recording processing unit 103 may divide a directory for each event number of the NFC card 20, or may provide a directory for each unique ID.

  With this configuration, since the terminal device 10 starts imaging when the NFC card 20 is presented, camera shake caused by touching the terminal device 10 during imaging can be reduced. In addition, since information embedded in the presented NFC card 20 can be acquired and embedded in the captured video, it is possible to use information related to the video after imaging, such as video search and grasping information at the time of imaging. it can.

  Next, the video composition process in step S106 will be described. In the storage unit 107 of the terminal device 10, composite video for performing synthesis on video captured by the imaging unit 102 is stored in a plurality of databases. Hereinafter, combining with the video for synthesis stored in four types of databases, that is, the unique ID linked video database 50, the remainder value linked video database 60, the unique ID linked position variable video database 70, and the event number linked video database 80. Processing will be described.

  With respect to the unique ID linked video database 50, the remainder value linked video database 60, and the unique ID linked position variable video database 70, the user selects in advance which database is to be combined. For the event number linked video database 80, the user sets in advance whether or not to perform the synthesis process. If the event number-linked video database 80 is set to perform the combining process, the terminal device 10 performs the combining process when the tag information acquired from the NFC tag 21 has an event number. When there is an event number in the tag information, the terminal device 10 performs a compositing process with the compositing video in the event number-linked video database 80 in preference to other databases.

  FIG. 5 is a diagram showing an outline of the unique ID-linked video database 50. There are two types of video for synthesis: video for which the synthesis position is determined in advance with respect to the original video to be synthesized, and video for changing the synthesis position according to the original video. The video whose composition position is determined in advance includes, for example, a so-called frame video in which a frame is added to the original video. The video for changing the synthesis position includes, for example, a video showing the ears of animals synthesized on the head of the subject.

  In the unique ID-linked video database 50, video for synthesis such as frame video in which a synthesis position is determined in advance is stored. In the unique ID linked video database 50, a value corresponding to the hash value of the unique ID acquired from the NFC tag 21 is stored in the unique ID hash value item 51, and a composition video is stored in the video data item 52. . The unique ID linked video database 50 associates the hash value of the unique ID with the composition video.

  Note that the value stored in the unique ID hash value item 51 is not necessarily a single value. A plurality of unique ID hash values may be associated with one composition video.

  FIG. 6 is a flowchart showing a video composition process using the composite video in the unique ID-linked video database 50. When the synthesizing process by the unique ID linked video database 50 is selected in advance by the user, the process is performed according to this flowchart.

  First, the video recording processing unit 103 searches the video corresponding to the unique ID in the unique ID-linked video database 50 (step S111). Specifically, based on the hash value of the unique ID of the NFC tag 21 calculated by the information acquisition unit 104, the video recording processing unit 103 has a composite video associated with the hash value of the same unique ID. Whether or not the unique ID linked video database 50 is searched. When there is a composition video associated with the hash value having the same unique ID as the calculated hash value, the video recording processing unit 103 sets the composition video to be synthesized with the captured video.

  Next, the video recording processing unit 103 determines whether or not a compositing video has been identified (step S112). If the composition video can be identified (Yes in step S112), the video recording processing unit 103 advances the process to step S113.

  The video recording processing unit 103 synthesizes the synthesis video and the captured video (step S113). Specifically, the video recording processing unit 103 synthesizes the searched synthesis video and the video acquired by the imaging unit 102, and ends the process as a subsequent processing target video.

  On the other hand, when there is no composite video corresponding to the hash value of the unique ID of the NFC tag 21 calculated by the information acquisition unit 104 (NO in step S112), the video recording processing unit 113 is acquired by the imaging unit 102. The obtained video is set as a video to be processed later, and the video compositing process is terminated.

  This configuration is more useful when the service provider that is the issuer of the NFC card 20 wants to provide a specific composite video to the distribution partner of the NFC card 20. The service provider can provide video for composition according to the user of the NFC card 20. For example, the advertising effect can be enhanced by distributing a frame image showing the beverage as a privilege to the user of the beverage which is his product.

  FIG. 7 is a diagram showing an outline of the remainder value linked video database 60. The residue value-linked video database 60 stores a video for synthesis whose synthesis position is determined in advance with respect to the video of the synthesis source. In the remainder value linked video database 60, the serial number is stored in the index item 61 and the video for synthesis is stored in the video data item 62, whereby the video for synthesis and the serial number are linked.

  FIG. 8 is a flowchart showing video composition processing using the composite video in the residue value-linked video database 60. When the synthesis process by the remainder value linked video database 60 is selected in advance, the process is performed according to this flowchart.

  The video recording processing unit 103 acquires the total number of compositing videos included in the remainder value linked video database 60 (step S121).

  Next, the video recording processing unit 103 divides the hash value of the unique ID by the total number of videos and calculates the remainder (step S122). Specifically, the video recording processing unit 103 divides the hash value of the unique ID acquired from the NFC tag 21 calculated by the information acquisition unit 104 by the total number of compositing videos acquired in step S121, and the remainder is calculated. calculate.

  Next, the video recording processing unit 103 identifies the video corresponding to the value of the calculation result from the video in the remainder value linked video database 60 (step S123). Specifically, the video recording processing unit 103 identifies the composite video with the serial number of the index item 61 corresponding to the calculated remainder from the composite video stored in the remainder value linked video database 60.

  Next, the video recording processing unit 103 synthesizes the identified synthesis video and the video acquired by the imaging unit 102 (step S124). The video recording processing unit 103 sets the synthesized video as a subsequent video to be processed, and ends the process.

  According to this configuration, the service provider that provides the composition video does not need to determine an index such as a unique ID in advance for the composition video. In addition, since each provided video for synthesis is used for synthesis almost at the same frequency, the video for synthesis can be used efficiently.

  FIG. 9 is a diagram showing an outline of the unique ID linking position variable video database 70. The unique ID linking position variable video database 70 stores a video for synthesis that varies the synthesis position in accordance with the video of the synthesis source. The unique ID hash value item 71 of the unique ID link position variable video database 70 stores a value corresponding to the hash value of the unique ID acquired from the NFC tag 21, and the video data item 72 contains the video data for synthesis. By storing, the hash value of the unique ID is associated with the composition video.

  FIG. 10 is a flowchart showing a video composition process using the composite video in the unique ID association position variable video database 70. When the composition process by the unique ID association position variable video database 70 is selected in advance, the process is performed according to this flowchart.

  The video recording processing unit 103 searches the video corresponding to the unique ID in the unique ID linked position variable video database 70 (step S131). Specifically, the video recording processing unit 103 stores the composite video corresponding to the hash value of the unique ID acquired from the NFC tag 21 calculated by the information acquisition unit 104 in the unique ID linked position variable video database 70. Search from videos stored in.

  The video recording processing unit 103 performs pattern recognition processing on the captured video, and specifies a synthesis position (step S132). Specifically, the video recording processing unit 103 specifies the position in the original video where the video for synthesis searched in step S131 is to be synthesized. For example, in the case of synthesizing an image in which glasses appear at the position of the face of a specific subject, the video recording processing unit 103 performs pattern recognition processing on the video acquired by the imaging unit 102 to identify the specified subject. Recognize the position of the face and try to identify the composite position.

  The video recording processing unit 103 determines whether or not the composite position has been specified (step S133). If the combination position is specified (YES in step S133), the process proceeds to step S134.

  The video recording processing unit 103 synthesizes the searched synthesis video at the specified position of the captured video (step S134). Specifically, the video recording processing unit 103 synthesizes the synthesis video searched in step S131 at the synthesis position specified by pattern recognition among the videos acquired by the imaging unit 102. The video recording processing unit 103 sets the synthesized video as a video for subsequent processing, and ends the process.

  In the above description, the position of the subject's face in the captured video is recognized as a combined position by pattern recognition, but the combined position is not limited to this. For example, a low contrast portion of the captured video is specified as a composite portion, and a ghost composition video is inserted into the composite portion, and a specific hue of the captured video is used as a composite position. It may be specified. With this configuration, the composition video specified by the NFC tag 21 can be synthesized at a specific position.

  FIG. 11 is a diagram showing an overview of the event number linked video database 80. The event number-linked video database 80 stores a composite video in which a composite position is determined in advance for the composite source video. A value corresponding to the event number acquired from the NFC tag 21 is stored in the event number item 81 in the event number associated video database 80, and the video data for synthesis is stored in the video data item 82, whereby the event number is stored. And video data for synthesis are associated with each other.

  FIG. 12 is a flowchart showing video composition processing using the composite video in the event number-linked video database 80. When the synthesis processing by the event number linked video database 80 is set to ON in advance and the event number is included in the tag information of the NFC tag 21 acquired by the information acquisition unit 104, the processing is performed according to this flowchart.

  The video recording processing unit 103 searches the event number-linked video database 80 for a video corresponding to the event number (step S141). Specifically, the video recording processing unit 103 searches the event number-linked video database 80 for a composite video associated with the event number among the tag information of the NFC card 20 acquired by the information acquisition unit 104. To do.

  Then, the video recording processing unit 103 synthesizes the searched synthesis video and the video acquired by the imaging unit 102 (step S142). The video recording processing unit 103 sets the synthesized video as a video for subsequent processing, and ends the process.

  According to this configuration, the user who has obtained the NFC card 20 in which the event number is recorded at the event can synthesize the video shot using the card with the video for synthesis corresponding to the content of the event. . For example, it is possible to perform composition suitable for an event by composing a frame image displaying the title of the event or the date and time of the event as a composition video.

  As described above, the synthesizing process performed using four types of databases has been described, but it goes without saying that the database used for the synthesizing process is not limited to the above-described types. In addition, although it is assumed that the user selects in advance which of the four types of databases is used for the synthesis, the user may set on / off in advance for each database. Also, the synthesis priority for each database is not limited to the above-described embodiment.

  Furthermore, you may superimpose and synthesize | combine the image | video for a synthesis | combination stored in multiple types of database. For example, a logo image may be combined with a frame image, which is a composition image corresponding to the hash value of the unique ID, as a composition image corresponding to the event number. Further, the composition processing may be performed by superimposing the composition video to be synthesized on a part of the body of the subject on the frame video as the composition video corresponding to the event number.

  (First Modification of Imaging Process)

  Next, a first modification of the imaging process will be described. The first modified example is an example in which continuous shooting processing of still images is performed by presenting the NFC tag 21. The still image continuous shooting process is performed by a stop command type still image continuous shooting process or a number designation type still image continuous shooting process. The user selects and sets in advance a stop command type still image continuous shooting process or a number designation type still image continuous shooting process.

  FIG. 13 is a flowchart showing stop command type still image continuous shooting processing. The stop command type still image continuous shooting process will be described below. In the stop command type still image continuous shooting process, continuous shooting of a still image is started by holding the NFC card 20 over the terminal device 10, and continuous shooting is stopped when the NFC card 20 is held again. First, when the NFC tag 21 is presented to the terminal device 10 and the tag detection unit 101 detects the NFC tag 21, a stop command type still image continuous shooting process is started.

  First, the information acquisition unit 104 reads tag information from the NFC tag 21 (step S201). Specifically, the information acquisition unit 104 acquires tag information of the NFC tag 21 from the NFC tag 21.

  Then, the imaging unit 102 captures the video output from the camera unit 14 as a still image (step S202). Hereinafter, the processing performed from step S203 to step S208 is the same as the processing performed from step S105 to step S110, and thus the description thereof is omitted.

  The imaging unit 102 determines whether the tag detection unit 101 detects the NFC tag 21 again (step S209). When the tag detection unit 101 does not detect the NFC tag 21 again (NO in step S209), the process returns to step S202, and the imaging unit 102 captures an image. The captured video is stored in the storage unit 107 by adding the hash value and event number of the unique ID to the Exif information by the video recording processing unit 103 through the processing from step S203 to S208. This process is performed in a loop until the NFC tag 21 is presented again to the tag detection unit 101.

  If the tag detection unit 101 detects the NFC tag 21 again (YES in step S209), the process ends.

  Next, the number designation type still image continuous shooting process will be described. In the number designation type still image continuous shooting process, the user sets the number of still images to be continuously shot in advance. When the NFC card 20 is held over the terminal device 10, a set number of continuous shots are performed.

  FIG. 14 is a flowchart illustrating the number designation type still image continuous shooting process. When the tag detection unit 101 detects the NFC tag 21, the number designation type continuous shooting process is started.

  The information acquisition unit 104 reads tag information from the NFC tag 21 (step S221). Since the processing performed from step S222 to step S228 is the same as the processing performed from step S104 to step S110, description thereof is omitted.

  The image capturing unit 102 determines whether or not a predetermined number of images have been captured (step S229). When the predetermined number of images that have been set have not been captured (NO in step S229), the imaging unit 102 returns to step S222 and performs an imaging process. The processing from step S222 to step S229 is performed in a loop until a predetermined number of images are captured.

  If a predetermined number of images have been captured (YES in step S229), the process ends.

  As described above, the stop command type still image continuous shooting process and the number designation type still image continuous shooting process have been described as the still image continuous shooting process, but the control of the still image continuous shooting process is not limited to these two types. While the tag detection unit 101 detects the NFC tag 21, continuous shooting may be performed continuously, and the continuous shooting may be terminated when the NFC tag 21 is removed from the terminal device 10.

  In the first modification of the imaging process described above, the video composition process is performed every time a video is captured. However, the still image continuous shooting process is first performed, and the video composition process is performed collectively after the continuous shooting process is completed. It is good as well.

  (Second Modification of Imaging Process)

  Next, a second modification of the imaging process will be described. The second modified example is an example in which moving image capturing processing is performed by presenting the NFC tag 21. In this embodiment, the imaging process is performed by a stop command type moving image capturing process or an imaging time designation type moving image capturing process. The user selects and sets in advance whether the stop command type moving image capturing process or the imaging time designation type moving image capturing process is performed.

  The stop command type motion imaging process is an example in which imaging of a moving image starts when the NFC tag 21 is presented to the terminal device 10, and imaging of the moving image ends when the NFC tag 21 is presented again.

  FIG. 15 is a flowchart showing the stop command type moving image capturing process. When the tag detection unit 101 detects the NFC tag 21, the process is started.

  The information acquisition unit 104 reads tag information from the NFC tag 21 (step S231). Specifically, the information acquisition unit 104 acquires tag information of the NFC tag 21 from the NFC tag 21.

  The imaging unit 102 starts capturing a moving image (step S232). Specifically, the imaging unit 102 starts capturing the moving image output by the camera unit 14.

  The tag detection unit 101 detects the NFC tag 21 (step S233).

  The imaging unit 102 stops capturing the moving image (step S234). Specifically, the imaging unit 102 stops imaging for the moving image whose imaging has started in step S232.

  The video recording processing unit 103 adds the hash value of the tag information (unique ID) to the meta information of the captured moving image (Step S235). The processing performed from step S236 to step S238 is the same as the processing performed from step S108 to step S110 in the imaging processing of FIG.

  Next, an imaging time designation type moving image imaging process will be described. In the imaging time designation type moving image imaging process, the user sets a time for continuously capturing a moving image, and presents the NFC tag 21 to the terminal device 10, thereby continuing the imaging of the moving image over the set time.

  FIG. 16 is a flowchart showing an imaging time designation type moving image imaging process. When the tag detection unit 101 detects the NFC tag 21, an imaging time designation type moving image imaging process is disclosed.

  The information acquisition unit 104 reads tag information from the NFC tag 21 (step S241). Specifically, the information acquisition unit 104 acquires tag information of the NFC tag 21 from the NFC tag 21.

  The imaging unit 102 starts capturing a moving image (step S242). Specifically, the imaging unit 102 starts capturing the moving image output by the camera unit 14.

  The imaging unit 102 continues imaging for a predetermined time (for example, 30 seconds) set in advance by the user (step S243).

  When the set imaging time has elapsed, the imaging unit 102 ends the imaging process (step S244). Specifically, the imaging unit 102 ends the moving image imaging process started in step S242. The processing performed from step S245 to step S248 is the same as the processing performed from step S107 to step S110, and thus the description thereof is omitted.

  According to the second modification of the imaging process, it is possible to start capturing a moving image by presenting the NFC tag 21 to the terminal device 10, so that it is possible to prevent the image from being disturbed due to camera shake during moving image capturing. Also, attribute information read from the NFC tag 21 can be added to the captured moving image and recorded.

  Note that a moving image can be combined with a predetermined video or can be partially combined by pattern recognition. Also, the moving image capturing process is not limited to the stop command type moving image capturing process and the imaging time designation type moving image capturing process. For example, moving image capturing may be performed while the NFC card 20 is held over the terminal device 10, and moving image capturing may be terminated when the NFC card 20 is removed from the terminal device 10.

  (Search procedure)

  Next, a procedure for a user to perform a search in the terminal device 10 will be described. A procedure for searching for a video recorded in the storage unit 107 of the terminal device 10 will be described as a local search procedure, and a procedure for searching for a video stored in a server connected to a network will be described as a server search procedure.

  (Local search procedure)

  FIG. 17 is a diagram for explaining a series of flows in the local search procedure. In the terminal device 10, a video in which a hash value of a unique ID is included in the meta information is recorded in advance.

  In the terminal device 10, a search application is activated based on a user instruction (step S301).

  When the user holds the NFC tag 21 over the terminal device 10, the tag detection unit 101 detects the held NFC tag 21 (step S302).

  The terminal device 10 executes a search process for searching for a video imaged using the NFC tag 21 (step S303).

  The terminal device 10 displays the searched video (step S304). Specifically, the videos listed as a result of the search process are displayed on the display 15 under the control of the video acquisition unit 105.

  Note that the video searched in the local search procedure is not limited to the video shot by the presentation of the NFC card 20. For example, it may be a video acquired from the Internet or external media.

  Next, the search process executed in step S303 will be further described.

  FIG. 18 is a flowchart showing search processing in the local search procedure. The NFC tag 21 to be used only needs to have a unique ID.

  Hereinafter, in the imaging process, for convenience, it is assumed that an image captured using the NFC tag 21 whose hash value of the unique ID is “aabbccdd” is stored in the storage unit 107. In the video, the hash value “aabbccdd” of the unique ID is recorded in the Exif information by the imaging process described above. When the tag detection unit 101 detects the NFC tag 21, the control unit 100 of the terminal device 10 starts a search process.

  The information acquisition unit 104 reads the tag information of the NFC tag 21 (step S311).

  Next, the information acquisition unit 104 calculates a hash value from the tag information (unique ID) (step S312). Specifically, the information acquisition unit 104 calculates a hash value using a predetermined hash function for the unique ID of the NFC tag 21 included in the tag information. Here, when the same NFC tag 21 as that at the time of imaging is presented, the information acquisition unit 104 calculates “aabbccdd” as a hash value.

  Next, the video acquisition unit 105 acquires Exif information of all videos of the terminal device 10 (step S313). Specifically, the video acquisition unit 105 acquires the Exif information of the video stored in the directory that stores the video acquired by the imaging unit 102 in the storage unit 107.

  Next, the video acquisition unit 105 compares the hash value of the unique ID in the Exif information with the calculated hash value (step S314). Specifically, the video acquisition unit 105 includes the hash value of the unique ID included in the Exif information of the video acquired in step S313 and the hash value of the unique ID of the NFC tag 21 acquired by the information acquisition unit 104 in step S311 “ aabbccdd ".

  Next, the video acquisition unit 105 adds a video having Exif information having a matching unique ID to the list (step S315). Specifically, the video acquisition unit 105 identifies a video having a unique ID hash value as a result of comparison, and adds it to the acquisition list. That is, the video acquisition unit 105 identifies a video having a unique ID hash value of “aabbccdd” in the Exif information among the videos stored in the storage unit 107 and adds the video to the acquisition list.

  If the comparison has not been completed for all the videos in the directory (NO in step S316), the process returns to step S314, and the video acquisition unit 105 executes the processes from step S314 to step S316. When the comparison is completed for all the videos in the directory (YES in step S316), the video acquisition unit 105 ends the process.

  For the video added to the list, the video acquisition unit 105 acquires information for specifying the storage position on the file system and displays it using a viewer.

  With this configuration, a video captured using the NFC tag 21 can be easily identified by performing a search process using the same NFC tag 21.

In the processing in this flowchart, the video is searched based on the unique ID included in the tag information acquired from the NFC tag 21, but the information that is the basis of the search is not limited to the unique ID. The user can set in advance which information is to be searched based on the information included in the tag information, and the video acquisition unit 105 can perform the search based on the set information.
(First modification in local search procedure)

  Next, a first modification of the local search procedure will be described. In the first modified example of the local search procedure, the video imaged by the imaging process in the terminal device 10 is recorded in a different directory for each unique ID hash value in the storage unit 107. In the following, it is assumed that the video imaged by the imaging process in the terminal device 10 is stored in a directory whose directory name is the hash value of the unique ID.

  FIG. 19 is a flowchart showing the search process of the first modified example in the local search procedure. When the tag detection unit 101 detects the NFC tag 21, the search process is started.

  The information acquisition unit 104 reads the tag information of the NFC tag 21 (step S321).

  The information acquisition unit 104 calculates a hash value from the tag information (unique ID) (step S322). Specifically, the information acquisition unit 104 calculates a hash value for the unique ID acquired from the NFC tag 21 using a predetermined hash function.

  The video acquisition unit 105 adds the video in the directory corresponding to the hash value to the list (step S323). Specifically, the video acquisition unit 105 specifies a directory having the same name as the hash value calculated by the information acquisition unit 104, adds the video in the directory to the acquisition list, and ends the process. For the video added to the list, the video acquisition unit 105 acquires information for specifying the storage position on the file system and displays it using a viewer.

  In this configuration, for a video imaged using the NFC tag 21, the video image is stored in a directory based on identification information unique to the NFC tag 21, and the directory is specified using the NFC tag 21 when searching. Thus, it is possible to easily identify the video.

  (Second modification in local search procedure)

  Next, a second modification of the local search procedure will be described. In the second modification of the local search procedure, the video acquired by the imaging process in the terminal device 10 is recorded in a different directory for each technical method of the NFC tag 21 in the storage unit 107. For example, an image captured using the NFC-A format NFC tag 21 is stored in the “A” directory, and an image captured using the NFC-B format NFC tag 21 is stored in the “B” directory. Yes.

  FIG. 20 is a flowchart showing the search process of the second modified example in the local search procedure. When the tag detection unit 101 detects the approach of the NFC tag 21, the search process is started.

  The information acquisition unit 104 reads information specifying the technical method from the NFC tag 21 (step S331). Specifically, the information acquisition unit 104 acquires information for specifying which technology method the NFC tag 21 detected by the tag detection unit 101 is based on. Here, it is assumed that information specifying the NFC-A technical method has been acquired.

  The video acquisition unit 105 adds the video in the directory corresponding to the read technical method to the list (step S332). Specifically, the video acquisition unit 105 adds the video in the directory corresponding to the information specifying the technical method acquired by the information acquisition unit 104 to the acquisition list, and ends the process. Here, since the information acquisition unit 104 has acquired information assumed to be based on NFC-A, the video acquisition unit 105 adds the video in the “A” directory to the acquisition list.

  If the NFC tag 21 is a one-time ID that does not have a uniquely determined unique number, the search process according to the first modification in the local search procedure can hardly identify the video. However, according to the second modification example in the local search procedure, the NFC tag 21 conforms to any one of the technical methods, and therefore, by presenting the same NFC card 20 as that at the time of imaging, the NFC card 20 performs imaging. A video including the recorded video can be acquired.

  The processing for acquiring video stored in a different directory for each hash value of the unique ID of the NFC tag 21 has been described as the first modification example in the local search procedure, and video stored in a different directory for each technical method. Has been described as a second modification of the local search procedure. In addition, it is good also as storing in a different directory for every event number.

  Also, a main directory is created based on any one of the hash value of the unique ID, information identifying the technical method, tag information such as event number, etc., and a subdirectory is created in the main directory based on other information For example, any of the methods described above may be combined. For example, the main directory may be divided for each technical method of the NFC tag 21, and a subdirectory may be provided for each unique ID hash value to store the video separately.

  In this case, the video acquisition unit 105 outputs the video in the directory corresponding to the tag information acquired from the NFC tag 21 without referring to the meta information of each video.

  Even if the video acquired via the network is stored in the storage unit 107, the video can be output by the above-described search process if the predetermined meta information is stored in the video.

  By storing the video in a different directory for each attribute information of the NFC tag 21, it is possible to specify the directory in which the video is stored from the NFC card 20 at the time of search, and to reduce the burden on the search processing.

  (Server search procedure)

  Next, a server search procedure will be described.

  FIG. 21 is a diagram for explaining an overview of the distribution system 50 having a configuration that is a premise of the server search procedure.

  The distribution system 50 includes the terminal device 10 and the server 30. The terminal device 10 is connected to the server 30 via the network 40. The server 30 can be connected to a plurality of terminal devices 10. In each terminal device 10, the video acquired by the above-described imaging process is stored in the server 30 via the network 40.

  When the NFC card 20 used in the imaging process is held over the terminal device 10, an image including meta information corresponding to the attribute information of the NFC tag 21 is searched in the server 30. The video specified by the search is displayed by the web browser on the terminal device 10 that has requested the search.

  FIG. 22 is a hardware configuration diagram of the server 30. The server 30 is an information processing apparatus, and includes a CPU 31, an input unit 32, a network I / F 33, a memory 34, and an HDD (Hard Disc Drive) 35, and the components are connected by a bus.

  The CPU 31 is a central processing unit and controls the entire server 30. The input unit 32 is an input device such as a keyboard and a mouse, and accepts input of operation instructions from the user. The network I / F 33 is an interface for connecting the server 30 to a predetermined data transmission path, whereby the server 30 can perform data communication with the terminal device 10.

  The memory 34 is a storage device, such as a RAM and a ROM (Read Only Memory). The HDD 35 is a storage device. The RAM of the memory 34 functions as a work area for the CPU 31, that is, a storage area from which programs and data are temporarily read. The HDD 35 is used as a storage location for programs and various data. Thereby, the server 30 reads the program stored in the ROM or the HDD 35 onto the RAM. In the server 30, processing is performed by the CPU 31 that operates according to the read program. The memory 34 may be an SSD (Solid State Drive).

  FIG. 23 is a functional block diagram of the server 30. In the following description, components necessary for the description of the present embodiment are shown for convenience.

  The server 30 includes a control unit 301 and a storage unit 310. The control unit 301 controls search processing in the server 30. The storage unit 310 records predetermined information such as authentication information about each terminal in addition to the captured video received from each terminal device 10.

  The control unit 301 includes a request reception unit 302, a video identification unit 303, an output information generation unit 304, and an authentication determination unit 305. The request receiving unit 302 receives a video distribution request from the terminal device 10. Note that the hash value of the tag information that is the attribute information of the NFC tag 21 is specified in the received distribution request.

  The video specifying unit 303 refers to the storage unit 310 and uses the tag information included in the distribution request to specify the video requested by the terminal device 10 from the videos stored in the storage unit 310. The output information generation unit 304 generates output information for displaying or delivering the identified video on the terminal device 10. The authentication determination unit 305 determines whether the terminal device 10 that has transmitted the distribution request is the terminal device 10 that has been authenticated.

  The storage unit 310 includes a collected video storage area 311. The collected video storage area 311 stores captured video received from each terminal device 10.

  In the search process of the terminal device 10, when the user performs a setting for searching the video in the server 30 and presents the NFC card 20, the URL specifying the attribute information of the NFC tag 21 included in the NFC card 20 is the terminal device 10. Is generated. The request reception unit 302 receives an HTTP request based on the generated URL. The video specifying unit 303 refers to the parameter in the HTTP request, specifies tag information that is attribute information of the NFC tag 21, and refers to the collected video storage area 311.

  When the video specifying unit 303 specifies a video having the same meta information as the tag information received by the request receiving unit 302 from the collected video storage area 311, the output information generating unit 304 uses the specified video to output information for output. Is generated.

  With this configuration, a plurality of terminal devices 10 can share the captured video. The terminal device 10 does not need to store the video in its own device.

  In addition, when the user holds the NFC card 20 over the terminal device 10, the user can easily view and acquire the video stored in the server 30 from the terminal device 10. The server 30 can easily perform the search process by receiving the attribute information of the NFC tag 21 from the terminal device 10.

  FIG. 24 is a sequence diagram for explaining an example of a server search procedure. In the terminal device 10, the video acquired by the imaging process has already been transmitted to the server 30 and stored in the storage unit 310 of the server 30.

  Hereinafter, a case where the viewing authority related to the event number is given to a specific user will be described. The server 30 issues a user ID and a password to the terminal device 10 in advance. The server 30 stores the issued user ID and password as a user account.

  When viewing authority is given to the event manager for a specific event, the event number is associated with the user account and registered in advance in the server 30. There are one or more event numbers corresponding to the user account. A user related to the terminal device 10 specified by the user account corresponding to the event number can view a video associated with the registered event number among the videos stored in the server 30. That is, even if the video is associated with a different unique ID, the video can be viewed as long as the video is associated with the registered event number.

  First, a user inputs a user ID and a password to the terminal device 10 (step S41).

  As the authentication request process, the terminal device 10 transmits the user ID and password input by the user to the server 30 (step S42).

  The authentication determination unit 305 of the server 30 performs authentication processing and issues an authentication token to the terminal device 10 (step S43). Specifically, the authentication determination unit 305 determines whether there is a user account corresponding to the user ID and password received from the terminal device 10, and has a predetermined authority if there is a user account. The authentication token is transmitted to the terminal device 10 that has transmitted the authentication request. The terminal device 10 stores the received authentication token in the storage unit 107.

  The authentication token is information that proves that the user in the terminal device 10 holding the authentication token is authenticated. In other words, the authentication token is authentication information indicating that the terminal device 10 has been authenticated. The authentication token includes information for specifying the user ID stored as the user account.

  Next, the tag detection unit 101 in the terminal device 10 detects the approach of the NFC tag 21 (step S44).

  When the terminal device 10 reads the NFC tag 21, the terminal device 10 creates a URL for requesting distribution to the server 30, and sends an HTTP request including the hash value of the unique ID of the NFC tag 21, the event number, and the authentication token to the server 30. Transmit (step S45).

  When the server 30 recognizes the authentication token, the server 30 performs a search process using the hash value and event number in the received distribution request (step S46). The search process will be described in detail later.

  In the search process, when the video requested to be distributed by the terminal device 10 is specified, the output information generation unit 304 performs a screen generation process. Specifically, a web page screen that displays the specified video is generated.

  The generated web page screen is transmitted to the terminal device 10 (step S47). In the terminal device 10, the web page displayed by the web browser from the server 30 is displayed.

  The above description is a processing procedure in the case of granting video viewing authority for a specific user. This configuration is more useful when, for example, a large number of NFC cards 20 with the same event number and different unique IDs are issued at an event venue. If the event organizer is a video stored in the server 30 and having the same event number in the Exif information, the event organizer can view the video even if the video has a different unique ID in the Exif information.

  With this configuration, the video in the server 30 can be searched using the NFC tag 21. The server 30 can use the information acquired from the NFC tag 21 when searching for a video, thereby reducing the search burden.

  Next, an authentication request process performed in the terminal device 10 will be described.

  FIG. 25 is a flowchart showing the authentication request process.

  On the authentication screen, an input of a user ID and a password is accepted (step S411). Specifically, the distribution request unit 106 of the terminal device 10 displays an authentication screen and accepts input of a user ID and a password.

  Next, the distribution request unit 106 transmits the received user ID and password to the server 30 (step S412). The server 30 stores a user ID and a password as a user account. In the server 30, when the user ID and password transmitted by the distribution request unit 106 are stored as a user account, it is assumed that the terminal device 10 that has transmitted the user ID has been authenticated, and the terminal device 10 An authentication token is received from 30.

  The distribution request unit 106 determines whether the terminal device 10 has received the authentication token (step S413). When the distribution request unit 106 determines that the terminal device 10 has received the authentication token, the distribution request unit 106 treats the authentication as successful, and when the distribution request unit 106 determines that the terminal device 10 has not received the authentication token, treats the authentication as failed. . If the terminal device 10 has received the authentication token (YES in step S413), the process proceeds to step S414.

  The distribution request unit 106 stores the received authentication token in the storage unit 107 (step S414). Specifically, the distribution request unit 106 stores the authentication token received from the server 30 in the storage unit 107, and the process ends.

  In step S413, when the distribution request unit 106 determines that the authentication token has not been received (NO in step S413), the process proceeds to step S415.

  The distribution request unit 106 displays an authentication failure message on the display 15 and the process ends.

  The authentication token issued by the authentication determination unit 305 of the server 30 is information indicating that the terminal device 10 is an authenticated terminal.

  Next, the distribution request will be further described.

  FIG. 26 is a flowchart showing the distribution request process.

  The information acquisition unit 104 calculates a hash value from the tag information (unique ID) (step S421). Specifically, the information acquisition unit 104 calculates a hash value from the unique ID acquired from the NFC tag 21.

  Next, the distribution request unit 106 generates a URL based on the tag information of the NFC tag 21 (step S422). As parameters of the URL to be generated, (i) a hash value calculated from the unique ID, (ii) information specifying the technical method of the NFC tag 21, (iii) an event number recorded in the NFC tag 21, and (iv) an authentication token The URL is generated so as to include the above four parameters. Note that (iv) the authentication token is the authentication token stored in the storage unit 107 in step S414. The HTTP request parameter included in the URL can be said to be key information.

  Next, the distribution request unit 106 transmits an HTTP request based on the generated URL to the server 30 as a distribution request, and ends the process.

  With this configuration, the terminal device 10 designates the attribute information of the NFC tag 21 and makes a distribution request to the server 30. Note that not all of the above-mentioned four parameters constituting the URL need to be included in the URL. At least one of (i) a hash value calculated from the unique ID, (ii) information identifying the technical method of the NFC tag 21 and (iii) an event number recorded in the NFC tag 21 is used as a parameter in the URL. It only has to be included. (Iv) The authentication token may not be included in the URL, but when the terminal device 10 holds the authentication token, the distribution request unit 106 generates the URL so that the authentication token is included in the parameter. It is desirable.

  Next, the search process in step S46 will be further described.

  FIG. 27 is a flowchart (first half) showing search processing.

  The request reception unit 302 acquires parameters from the HTTP request (step S431). Specifically, the request receiving unit 302 refers to the HTTP request received from the terminal device 10 and acquires the parameters (the above (i) to (iv)) constituting the URL.

  Next, the video identification unit 303 acquires video metadata in the collected video storage area 311 (step S432). Specifically, the video specifying unit 303 acquires Exif information, which is meta information, for the video in the collected video storage area 311.

  The video specifying unit 303 determines whether or not there is an event number in the HTTP request (step S433). If there is no event number in the HTTP request (NO in step S433), the video specifying unit 303 advances the process to step S434. Specifically, if the event number is not included in the parameters acquired in step S431, the process proceeds to step S434.

  The video specifying unit 303 specifies the hash value of the unique ID from the HTTP request (step S434). Specifically, the video specifying unit 303 specifies the hash value of the unique ID of the NFC tag 21 among the parameters acquired in step S431.

  The video specifying unit 303 specifies a video in which the hash value that matches the hash value of the specified unique ID is recorded in the Exif information among the videos in the collected video storage area 311 (step S435).

  The output information generation unit 304 adds the identified video to the list, and ends the process (step S436).

  If there is an event number in the HTTP request in step S433 (YES in step S433), the process proceeds to step S437.

  FIG. 28 is a flowchart (second half) showing search processing.

  The video specifying unit 303 specifies the video corresponding to the event number (step S437). Specifically, the video specifying unit 303 specifies the video having the event number in the HTTP request in the Exif information from the video in the collected video storage area 311.

  Next, the authentication determination unit 305 acquires an authentication token from the HTTP request (step S438). Specifically, the authentication determination unit 305 identifies an authentication token that is one of the parameters in the HTTP request. The authentication token includes information for specifying the user ID of the user in the terminal device 10 that has transmitted the HTTP request.

  The authentication determination unit 305 acquires an event number corresponding to the authentication token (step S439). Specifically, the user account stored in the storage unit 310 is specified from the user ID specified from the information included in the authentication token, and the event number registered in association with the user account is acquired.

  The authentication determination unit 305 determines whether or not the event number acquired in step S439 matches the event number in the HTTP request (step S440). Specifically, the event number acquired in step S439 is compared with the event number included in the parameter of the HTTP request received from the terminal device 10, and if they match (in the case of YES in step S440), step S444 is performed. Proceed with the process.

  The video specifying unit 303 adds all the specified videos to the list (step S444). Specifically, when the event number corresponding to the authentication token matches the event number included in the HTTP request, the user of the terminal device 10 that has transmitted the HTTP request is registered in advance as an event manager. The video specifying unit 303 adds the video specified in step S437 to the list.

  In step S440, if the acquired event number does not match the event number registered in association with the user account (NO in step S440), the process proceeds to step S441.

  The video specifying unit 303 specifies the hash value of the unique ID of the NFC tag 21 from the HTTP request (step S441).

  Next, the video specifying unit 303 further specifies the video of the tag information corresponding to the hash value from the specified video (step S442). Specifically, the video specifying unit 303 specifies a video in which the hash value of the unique ID is further recorded in the Exif information from the videos specified in step S437.

  The video specifying unit 303 adds the video specified in step S442 to the list (step S443), and the process ends.

  With this configuration, an authorized user can be authorized to view and acquire a video, and can view a video with a predetermined event number even if a hash value with a different unique ID is assigned. become. For users who are not authorized, only the video associated with the unique identification information of the NFC tag 21 can be viewed from the video with the event number.

  Needless to say, the video distribution request can be configured not to require authentication processing. When a plurality of NFC cards 20 with event numbers assigned to the NFC tag 21 are issued, the user who has the NFC card 20 may be able to freely browse the video with the event numbers assigned.

  (Modification)

  Next, a search process in the modification will be described. In the modified example, in the collected video storage area 311, videos are classified into directories and stored based on Exif information included in videos captured by the imaging process. In this embodiment, a directory divided for each event number is set as a main directory, and a subdirectory is provided for each hash value of the unique ID of the NFC tag 21 in the main directory. Hereinafter, differences from the above-described embodiment will be described.

  FIG. 29 is a flowchart (first half) showing search processing in the modification.

  The request reception unit 302 acquires a parameter constituting the URL from the HTTP request (step S451).

  The video specifying unit 303 determines whether there is an event number in the HTTP request (step S452). If there is no parameter for specifying the event number among the parameters acquired by the request reception unit 302 (NO in step S452), the process proceeds to step S453.

  The video specifying unit 303 specifies a directory for storing a video without an event number (step S453). The directory for storing video without an event number is a directory for storing video without an event number in the meta information of the video.

  The video specifying unit 303 specifies the hash value of the unique ID from the HTTP request (Step S454).

  Next, the video specifying unit 303 specifies the video in the directory corresponding to the hash value (step S455). Specifically, the video specifying unit 303 specifies a video having the hash value of the unique ID specified in step S454 in the Exif information that is meta information from the directory that stores the video without the event number.

  The video specifying unit 303 adds the specified video to the list (step S456) and ends the process.

  In step S452, if the HTTP request received by the request receiving unit 302 includes a parameter for specifying an event number (YES in step S452), the process proceeds to step S457.

  FIG. 30 is a flowchart (second half) showing search processing in the modification.

  The video specifying unit 303 specifies the directory corresponding to the event number received by the request receiving unit 302 from the directories in the collected video storage area 311 (step S457).

  Next, the video specifying unit 303 acquires an authentication token from the HTTP request (step S458).

  Next, the authentication determination unit 305 acquires an event number corresponding to the authentication token (step S459). Specifically, the user account stored in the storage unit 310 is specified from the user ID specified from the information included in the authentication token, and the event number registered in association with the user account is acquired.

  Next, the authentication determination unit 305 determines whether or not the event number acquired in step S459 matches the event number in the HTTP request (step S460). Specifically, the event number acquired in step S459 is compared with the event number included in the parameter of the HTTP request received from the terminal device 10, and if they match (in the case of YES in step S460), step S464 is performed. Proceed with the process.

  The video specifying unit 303 adds the video in the specified directory to the list (step S464), and ends the process.

  In step S460, if the event number does not match the event number registered in association with the user account (NO in step S460), the video specifying unit 303 advances the process to step S461.

  The video specifying unit 303 specifies the hash value of the unique ID from the HTTP request (step S461). Specifically, the video specifying unit 303 specifies the hash value of the unique ID of the NFC tag 21 in the HTTP request received by the request receiving unit 302.

  Next, the video specifying unit 303 specifies the video in the subdirectory corresponding to the hash value from the specified directory (step S462).

  The video specifying unit 303 adds the video in the subdirectory specified in step S462 to the list (step S463), and ends the process.

  In the above embodiment, the main directory is generated based on the event number, and the subdirectory is generated based on the hash value of the unique ID, but the directory is generated based on the attribute information of the NFC tag 21. If it is done, it is not limited to this.

  In this configuration, since the video is classified and stored in the directory according to the attribute information of the NFC tag 21, the load on the server 30 in the search process can be reduced.
