Since image data is not provided to the user of the communication terminal apparatus 10 that is not located in the vicinity, the image data can be provided only to the user who is imaged.

  Therefore, in this embodiment, privacy can be protected without browsing image data by an unspecified logarithmic user, and unnecessary data can be prevented from being distributed.

  For example, in the event holding venue IA as shown in FIG. 2, when the user A captures an imaging target using the camera function of the own communication terminal device 10 as an imaging communication terminal device, the short distance wireless standard is used. An in-area terminal ID is acquired as an in-area communication terminal device from the communication terminal devices 10 of the users B and C existing in the range in which the transmitted inquiry signal can be received (hereinafter referred to as “peripheral terminal detection area”) DA. It will be.

  That is, if the communication terminal devices 10 of the user B and the user C are intra-area communication terminal devices, it is highly likely that the user B and the user C are captured in the image captured by the user A, and the captured and generated images are generated. It is necessary for users B and C to share the captured image.

  On the other hand, since the communication terminal device 10 of the user D exists outside the peripheral terminal detection area DA, it is assumed that the possibility that the user D is imaged on the imaging target captured by the user A is low. Therefore, it is not necessary for the user D to share the captured and generated image.

  Therefore, in the present embodiment, the image sharing server device 30 allows the user B and the user C to share the captured image to be captured with the user B and the user C together with the image data. The terminal ID is registered, and the user B and the user C can acquire the image by specifying their own terminal ID and event ID.

  In particular, in the example illustrated in FIG. 2, it is highly likely that the user C present in the direction opposite to the imaging direction of the imaging communication terminal device is not captured based on the operation instruction of the user A. Even when, for example, the user B is a celebrity, or when the user B is a main character such as a wedding, the user C can share image data even when the user C is not the subject of imaging. I often want to.

  Therefore, in the present embodiment, even in such a case, in order to execute image sharing for the user C, it is possible to view or acquire image data as long as it exists in the peripheral terminal detection area DA. The terminal ID is registered so that

  The current position detection unit 120 generates position information indicating the current position while detecting the current position of the communication terminal device 10 at every predetermined timing.

  For example, the current position detection unit 120 detects a satellite signal (GPS signal) transmitted from the GPS satellite while recognizing the position of the GPS (Global Positioning System) satellite 40 shown in FIG. 1 at a predetermined timing. Then, the current position detection unit 120 calculates (that is, detects) coordinate values (for example, latitude and longitude) of the current position of the own device based on the detected GPS signal, and performs data processing using the coordinate values as current position information. Part 180.

  When the communication terminal device 10 has a telephone function, the current position detection unit 120 uses the three-point survey method used in the long-distance wireless system, that is, the radio wave used for the telephone at the telephone base station. You may detect the present position of an own machine based on the received direction and field intensity.

  In addition, when the event venue is indoor, the current position detection unit 120 operates in conjunction with the short-range wireless communication unit 130, for example, radio wave strength and other signals with an access point (not shown) that transmits and receives signals for wireless LAN, and the like.

In accordance with various communication standards such as n various wireless LANs, communication with other communication terminal apparatuses 10 or other communication devices is performed.

  In particular, the short-range wireless communication unit 130 broadcasts a detection inquiry signal (for example, a beacon signal) to the other communication terminal devices 10 by using a predetermined communication format for short-range wireless communication. While receiving the response signal accompanying the signal, the terminal ID of the communication terminal device 10 that has transmitted the response signal is provided to the data processing unit 180 as the in-area terminal ID.

  For example, the short-range wireless communication unit 130 transmits a beacon signal including the terminal ID of its own device, such as an inquiry command permitted to be used by the BLUETOOTH (registered trademark) protocol, to the other communication terminal device 10, A response signal to which the terminal ID of the communication terminal device 10 is added (that is, a response signal to the beacon signal) is received from another communication terminal device 10 in a beacon signal reception standby state. Then, the short-range wireless communication unit 130 identifies the terminal ID of the other device from the received response signal and provides the data processing unit 180 with the terminal ID.

  The display unit 140 is configured by, for example, a panel of a liquid crystal element or an EL (Electro Luminescence) element, and displays a predetermined image based on display data generated by the display control unit 150.

  The display control unit 150 generates display data necessary for display on the display unit 140, and outputs the generated display data to the display unit 140.

  The timer 160 is used to specify the current date and time, and provides the data processor 180 with the date and time when the image was taken.

  The data processing unit 180 realizes each process to be executed based on a program such as an imaging application stored in the application storage unit 101 or an application that executes an event participation registration process. For example, the data processing unit 180 executes an imaging application, and executes an imaging process and an updater process while interlocking with each unit of the communication terminal device 10.

  Specifically, when the user recognizes a predetermined input operation on the operation unit 170, the data processing unit 180 outputs a command command to the imaging / image data generation unit 190 based on the imaging application, and the imaging / image data generation unit In 190, an imaging process is executed in which a mode or the like is determined in accordance with the command, and image data matching the mode or the like is generated.

  Then, the data processing unit 180 executes upload processing for registering the generated image data in the image data storage unit 102 in the imaging / image data generation unit 190. In addition, when the data processing unit 180 receives an inquiry signal from another communication terminal device 10 while the imaging application is activated, the data processing unit 180 transmits a response signal to the inquiry signal to the communication terminal device 10 that has transmitted the inquiry signal. Perform response processing.

[1.3] Configuration of Image Sharing Server Device Next, the configuration of the image sharing server device 30 according to the present embodiment will be described with reference to FIGS. FIG. 5 is a configuration diagram showing the configuration of the image sharing server device 30 of the present embodiment, and FIG. 6 shows an example of data recorded in the event DB 331 in the image sharing server device 30 of the present embodiment. FIG. FIG. 7 is a diagram illustrating an example of data recorded in the content DB 320 in the image sharing server device 30 according to the present embodiment.

  As illustrated in FIG. 5, the image sharing server device 30 according to the present embodiment includes a communication control unit 310, a ROM / RAM 320, a recording device 330, and a server management control unit 340 that integrally controls each unit of the image sharing server device 30. And having.

  The above units are connected to each other by a bus B, and data transfer is performed between the components.

  For example, the communication control unit 310 constitutes the data receiving means of the present invention, and the recording device 330 constitutes the database of the present invention. For example, the server management control unit 340 constitutes an extraction unit, a recording control unit, and a distribution unit of the present invention.

  The communication control unit 310 is a predetermined network interface, establishes a communication line with the communication terminal device 10, and exchanges various data for sharing content data.

  Various programs necessary for driving the image sharing server device 30 are recorded in the ROM / RAM 320. The ROM / RAM 320 is used as a work area when various processes are executed.

  The recording device 330 is configured by an HDD, and an event DB 331 and a content DB 332 are constructed in the recording area.

The event DB 331 is a DB in which event information for managing each event held in the real world and a participating user of each event is stored as data. For example, in the event DB 331, as shown in FIG.
(1) Event holding location information indicating the location of the event venue (2) Event ID assigned to each event and uniquely identifying each event
(3) Event summary information indicating the summary of the event such as the name or type of the event (4) Event date and time information indicating the date and time of the event,
(5) The terminal ID of the communication terminal device 10 possessed by the user who has registered in advance to participate in the event by the event participation registration process is recorded in association with it.

  Specifically, in the case of the example shown in FIG. 6, as the event ID “event1”, the event “live concert” is the event holding position “north latitude (N): 35: 02: 11 / east longitude (E): The terminal IDs “MS1 to MS4” that are held at the event venue specified at “140: 01: 20” and have already been registered for registration are stored in association with each other. In other words, the “live concert” specified by “event1” indicates that the user having the communication terminal device 10 specified by the terminal ID “MS1 to 4” is registered for participation.

  Similarly, as the event IDs “event2” to “event6”, various events are stored in association with the terminal IDs “MS5 to 8” at the event holding venue specified at each holding position. .

  In the event DB 331, as each event is added and the number of participating users in each event is increased or decreased, the number of fields for each event or the number of stored fields of terminal IDs is also increased or decreased.

  In addition, as shown in FIG. 6, when events registered simultaneously in different halls or different floors in the same building are held at different dates and times at the same place, It can be identified by the holding position information. For example, in FIG. 6, in the present embodiment, the event location specified by the location information of the location information “north latitude (N): 35: 02: 11 / east longitude (E): 140: 01: 20” is used. The three events, “Live Concert”, “Fashion Show”, and “Admission Ceremony” will be held at different times.

  The content DB 332 is a DB for managing the image data to be imaged captured by the communication terminal device 10 at the event venue and the communication terminal device 10 to which the image data is to be distributed.

For example, in the content DB 332, as shown in FIG.
(1) Event ID,
(2) Image data of an imaging target captured at an event corresponding to the event ID,
(3) the imaging terminal ID of the communication terminal apparatus 10 that captured the image data;
(4) In-area terminal ID of the communication terminal device 10 registered at the time of capturing the image data
Are recorded in association with each other.

  These image data are uploaded from the communication terminal device 10. Moreover, browsing and acquisition of image data associated with the recorded imaging terminal ID and in-area terminal ID are permitted.

  In FIG. 7, in “event: 1” to “event: 3”, “data1” to “data6” are stored in association with each other, and viewed or associated with each of “data1” to “data6”. Each terminal ID “MS” that can be acquired is stored in association with each other.

  The server management control unit 340 is mainly configured by a central processing unit (CPU), and by executing a program, operation management of the communication control unit, information management of event information, and event registration in each communication terminal device 10 Management, image data upload and distribution management, and management and control of the recording device 330.

  Specifically, the server management control unit 340 works in conjunction with the recording device 330 to perform registration processing and management of each user's event based on an instruction from the communication terminal device 10 by a user operation, and the recording device 330. The data distribution processing is performed to control the distribution of the image data when the user desires.

  In particular, the server management control unit 340 performs an event based on an instruction transmitted from the communication terminal apparatus 10 during the event participation registration process or during the image data provision process for distributing (providing) image data to the communication terminal apparatus 10. List data, user list data or image list data is generated, and event registration or data distribution is executed based on each list data.

  The event list data includes event information, event ID, date and time information, and if there is a user who has registered for participation in each event, the event list data includes the terminal ID of the communication terminal device 10 of the user, and a predetermined event This is data for displaying and selecting a list of events to be held at the venue at the communication terminal device 10.

  Further, the user list data is data including the terminal ID registered for each event information and the user name information registered at the time of event participation registration.

  Furthermore, the image list data is data for causing the communication terminal device 10 to display and select a list of image data associated with the terminal ID of the communication terminal device 10 to be provided.

[1.4] Operations of Communication Terminal Device and Image Common Server Device Next, specific processing of the communication terminal device and the image sharing server device executed in the communication system of the present embodiment with reference to FIGS. explain.

[1.4.1] Event Participation Registration Process before Event]
First, the operations of the communication terminal device and the image sharing server device will be described with reference to FIG. 8 regarding event participation registration processing before the event of the present embodiment. FIG. 8 is a flowchart showing event participation registration processing in the communication terminal device and the image common server device of the present embodiment.

  The event participation registration process is a process that is essential (prerequisite) for recording necessary data in the event DB 331 and receiving the provision of an image sharing service, and can perform an imaging process and an upload process after the start of the event. Is to do. For this reason, the image sharing service itself is not provided to users who have not registered for participation.

  Before the event participation registration process is executed, event summary information and an event are held using the communication device (not shown) such as a computer or an input device that can communicate with the image sharing server device 30 via the network 20. It is assumed that location information and event date information are registered in advance by the event organizer together with the event ID in each field in the event DB 331.

  Furthermore, it is assumed that the event participation registration process is executed at or near the event venue in the communication terminal device 10.

  First, in the communication terminal device 10, when the data processing unit 180 detects an operation input by a user via the operation unit 170 (step S101), the data processing unit 180 outputs a command command to the current position detection unit 120, and the current position detection unit In 120, position information corresponding to the current position of the communication terminal device 10 (that is, at or near the event venue) is detected (step S102).

  Next, the data processing unit 180 reads the browser, transmits an event participation registration request to which the position information is added, to the image sharing server device 30, and event list data in which events held near the current position are listed. Is waited for (step S103).

  On the other hand, in the image sharing server device 30, when receiving the event participation registration request from the communication terminal device 10 (step S200), the server management control unit 340 executes the following routine.

  First, the server management control unit 340 extracts the current position information added to the event participation registration request (step S201), and searches the event DB 331 using the extracted position information as a search key (step S202).

  Specifically, in the process of step S202, the server management control unit 340 identifies event holding position information that matches the extracted current position information from the event DB 331, and records the event holding position information in association with the holding position information in the event DB 331. The event ID that is being used is specified.

  Next, the server management control unit 340 uses the event information associated with the identified event ID, the date and time information of the event, and, if the terminal ID has already been stored, the event list using the terminal ID. Data is generated and distributed to the communication terminal device 10 (step S203).

  At this time, in the communication terminal device 10, when the data processing unit 180 receives the event list data distributed from the image sharing server device 30 via the network communication unit 110 (step S109), the data processing unit 180 controls the display control unit 150. Event list data is displayed on the display unit 140 (step S110). Specifically, the display control unit 150 performs a list of events held at or near the current position of the user (that is, the event venue where the user is located) by this process (for example, event information and the date and time of the event). Information) is displayed on the display unit 140 in a selectable manner.

  Next, when the data processing unit 180 detects a registration participation event in which the user participates based on a user operation via the operation unit 170 (step S111), the ID of the participation registration event selected by the user included in the event list data Is extracted to identify a participation registration event, and input of event participation registration information regarding the user in the event is accepted (step S112). At this time, the data processing unit 180 is linked with the operation unit 170 and the display control unit 150, and participates in event participation registration information such as a user name, a password and age for accessing the image sharing server device 30, an address, and other personal information. Accepts input.

  Next, when the input of the event participation registration information is completed, the data processing unit 180 transmits the event participation registration information to which the event ID selected for participation registration and the terminal ID of the own device are added to the image sharing server device 30, It waits for reception of user list data in which the users already associated with the event ID are stored (step S112).

  On the other hand, in the image sharing server device 30, when receiving the event participation registration information (step S211), the server management control unit 340 extracts various information such as an event ID and a terminal ID included in the event participation registration information. The event DB 331 is updated based on the extracted data such as the event ID (step S212).

  Specifically, the server management control unit 340 specifies the terminal ID storage field of the event DB 331 based on the event ID added to the participation registration request, and the terminal ID and personal information as necessary in the specified field. Record.

  Next, the server management control unit 340 generates user list data including a terminal ID recorded in association with the event ID and a user name corresponding to the terminal ID, and distributes the data to the communication terminal device 10 ( Step S213), this operation is finished.

  In the communication terminal device 10, when the data processing unit 180 receives the user list data (step S 115), the data processing unit 180 controls the display control unit 150 to display the user list data on the display unit 140 while storing the event information. This is stored in the unit 104 (step S116), and this operation is terminated.

  As described above, in the present embodiment, the event DB 331 as illustrated in FIG. 6 is constructed in the image sharing server device 30 so that user registration is completed.

  This operation is performed in the communication terminal device 10 near the event venue where the participation registration is desired. However, even if the event terminal is far from the event venue, the event is performed based on the user operation. One event may be selected from the event list data by specifying the holding position.

  In this case, the event participation registration process may be performed by another communication device such as a fixed personal computer by inputting the terminal ID individually instead of the communication terminal device 10.

[1.4.2] Operations of Imaging Processing and Upload Processing Next, operations of the communication terminal device 10 and the image sharing server device 30 in the imaging processing and upload processing will be described with reference to FIG. FIG. 9 is a flowchart illustrating the imaging process and the upload process in the communication terminal apparatus 10 and the image sharing server apparatus 30 according to the present embodiment.

  This operation is an operation that is executed in the event venue in each communication terminal device 10 that is in the check-in state after the event starts.

  Further, it is assumed that the image sharing server device 30 has already stored a plurality of pieces of event information in the event DB 331 and is in a state of waiting for uploading of image data from each communication terminal device 10.

  Then, the communication terminal device (imaging communication terminal device) 10 that executes the imaging process and the upload process has already started the imaging application and is in a check-in state with respect to a predetermined event. It is assumed that a plurality of other communication terminal devices (intra-area communication terminal devices) 10 have already started the imaging application and are in a check-in state with respect to the same event at the event venue.

  In this operation, in the actual event venue, there are a plurality of communication terminal devices 10 serving as in-area communication terminal devices in the peripheral terminal detection area, but the processing in each communication terminal device 10 is the same. Description will be made using only one communication terminal device 10.

  First, in the communication terminal device (imaging communication terminal device) 10, when the data processing unit 180 detects an operation instruction for performing imaging by the user via the operation unit 170 in the event holding venue after the start of the event, (step) S10), an instruction command for generating image data is output to the imaging / image data generation unit 190, and the imaging / image data generation unit 190 controls the optical system based on the instruction command to image the imaging target. Then, the image data to be imaged is generated (step S11).

  Next, the data processing unit 180 outputs a recording command command for the generated image data to the imaging / image data generation unit 190, and the imaging / image data generation unit 190 transmits the command to the image data storage unit 102 based on the command. The image data writing process is executed (step S12).

  Next, the data processing unit 180 outputs a command command for transmitting a beacon signal to the short-range wireless communication unit 130, and the short-range wireless communication unit 130 uses the input of the command as a trigger to check in an event. The beacon signal to which the ID is added (that is, the detection inquiry signal of the other communication terminal device 10) is simultaneously transmitted in the peripheral terminal detection area (step S13).

  At this time, in the communication terminal device (in-area communication terminal device) 10, when the data processing unit 180 receives a beacon signal via the short-range wireless communication unit 130 (step S21), the event ID is extracted from the beacon signal. Then, it is determined whether the event ID stored in the event information storage unit 104 is a checked-in event ID (step S22). In this process, if the extracted event ID is an event ID stored in the event information storage unit 104 and a checked-in event ID, the data processing unit 180 proceeds to the process of step S23. Otherwise, this operation is terminated.

  Next, the data processing unit 180 adds the terminal ID of the own device recorded in the storage unit 100 and the event ID in the check-in state to the received beacon signal via the short-range wireless communication unit 130. A signal (that is, a response signal to the beacon) is returned (step S23), and this operation is terminated.

  On the other hand, in the communication terminal device (imaging communication terminal device) 10, when the short-range wireless communication unit 130 receives a response signal to the beacon transmitted as described above (step S14), the data processing unit 180 receives the response signal. The terminal ID in the area is extracted and acquired (step S15), and the image data management table T1 is updated (step S16).

  Specifically, the data processing unit 180 assigns an image data ID to the generated image data, and assigns the image data ID and event ID, the recording address of the image data, and the terminal ID acquired in step S15. Correspondingly, the image data management table T1 is stored.

  As a result, data as shown in FIG. 4 is recorded in each field in the image data management table T1. To explain more simply, the communication terminal device 10 in which the terminal ID is registered at this time is registered in the image data as a sharing target of the captured image data.

  Next, the data processing unit 180 controls the network communication unit 110 to execute an image data upload process (step S17). At this time, the data processing unit 180 transmits the image data and the image data management table T1 as the data D1 from the communication terminal device 10 as the imaging communication terminal device to the image sharing server device 30 by upload processing.

  On the other hand, in the image sharing server device 30, when the server management control unit 340 receives image data or the like via the communication control unit 310 (step S31), the communication terminal device 10 as an imaging communication terminal device is received from the received data D1. Terminal ID and event ID and image data and image data management table T1 are extracted (step S32).

  Next, the server management control unit 340 includes the terminal ID, event ID, image data, and terminal ID in the image data management table T1 of the communication terminal device (imaging communication terminal device) 10 (that is, as an in-area communication terminal device). Terminal ID) is recorded in the corresponding field of the content DB 332 (step S33). As a result, data is recorded in the content DB 332 with the configuration illustrated in FIG.

  Next, the server management control unit 340 generates user list data including a terminal ID stored in association with the event ID and a user name corresponding to the terminal ID, and distributes the data to the communication terminal device 10 ( Step S34), this operation is finished.

  In the communication terminal device (imaging communication terminal device) 10, when the data processing unit 180 receives the user list data (step S18), the data processing unit 180 controls the display control unit 150 to display the subordinate user list data. Is displayed in the event information storage unit 104 (step S19), and this operation is terminated.

  In this way, the image data is stored in the content DB 332, and the process is the same when the image is taken by another communication terminal apparatus 10, and such a series of processes is repeated many times. By being repeated, a large number of image data is accumulated in the content DB 332.

  In FIG. 9, the data processing unit 180 in the imaging communication terminal apparatus performs uploading when the update of the image data management table T1 is completed, but the timing of the uploading process is arbitrary. For example, the image data may be uploaded based on the user's instruction when the user has sufficient time, such as after the end of the event. In this case, when the user performs a predetermined input operation on the operation unit 170 of the communication terminal device 10, the process of step S20 is executed.

[1.4.3] Operation of Image Data Providing Process Next, operations of the communication terminal apparatus 10 and the image sharing server apparatus 30 in the image data providing process will be described with reference to FIGS. FIG. 10 is a flowchart showing image data provision processing in the communication terminal device 10 and the image sharing server device 30 according to the present embodiment, and FIG. 11 is a diagram showing an example of a thumbnail image displayed on the display unit 140. is there.

  In this operation, it is assumed that the above-described imaging process and upload process have already been executed, and the image sharing server apparatus 30 has accumulated a large number of image data for each event. Further, the communication terminal apparatus 10 reads out the browser recorded in the application storage unit 101 and starts up on the OS, and the image sharing server apparatus 30 performs each event (specifically, for each event ID). The image data is provided based on the managed unique URL.

  First, in the communication terminal device 10, when the data processing unit 180 identifies an event via the operation unit 170 and detects an operation instruction in the browsing acquisition of image data by the user (step S400), the image sharing server device according to the input operation. An image data browsing acquisition request is transmitted to 30 (step S401), and reception of image list data is awaited. At this time, the data processing unit 180 transmits the image data acquisition request with its own terminal ID added thereto.

  When the image processing server device 30 acquires a list of image data based on the URL assigned for each event as the user operation, the data processing unit 180 inputs the URL or bookmarks the browser. If a URL is registered in advance for a corresponding event due to a function or the like, an input to simply access the image sharing server device 30 is detected.

  In the image sharing server device 30, when receiving the image data browsing acquisition request (step S300), the server management control unit 340 extracts the terminal ID added to the image data browsing acquisition request (step S301).

  Next, the server management control unit 340 searches the event DB 331 using the extracted terminal ID as a search key, and performs a user authentication process in the communication terminal device 10 specified by the terminal ID (step S302). At this time, the server management control unit 340 may execute the authentication process using other data such as a password.

  Next, when the authentication is successful through the authentication process, the server management control unit 340 reads the stored event ID associated with the URL (step S303).

  Next, the server management control unit 340 is recorded in the content DB 332 in association with the same event ID as the read event ID, and the imaging terminal ID and in-area terminal ID that match the extracted terminal ID Is read out, and the image data read out in the RAM 320 is expanded to generate thumbnail image data for displaying a list of the image data (step S304).

  Next, the server management control unit 340 distributes the generated thumbnail image data to the communication terminal device 10 that is the transmission source of the image data browsing acquisition request via the communication control unit 310 and acquires the image data from the communication terminal device 10. Waiting for reception of the request (step S305).

  On the other hand, in the communication terminal device 10, when the data processing unit 180 receives thumbnail image data via the network communication unit 110 (step S410), the data processing unit 180 controls the display control unit 150 to store the received thumbnail image data. The display command is output to the display control unit 150 and the thumbnail image data temporarily recorded on the RAM is displayed on the display unit 140 (step S411). For example, as shown in FIGS. 11A and 11B, the display unit 140 displays thumbnails of image data captured at an event that the user has registered for participation.

  Next, when the data processing unit 180 detects an operation (hereinafter referred to as “selection operation”) to acquire one or a plurality of image data by the user via the operation unit 170 (step S412), the data selection unit 180 selects the user. The image data ID associated with the thumbnail is extracted from the thumbnail image data, and an image data acquisition request to which the extracted image data ID and the terminal ID of the own device are added is transmitted (step S413).

  At this time, in the image sharing server device 30, when the server management control unit 340 receives the image data acquisition request via the communication control unit 310 (step S310), the image management server 340 searches for the image data ID added to the image data acquisition request. The content DB 332 is searched as a key, and one image data is specified (step S311).

  Next, the server management control unit 340 distributes the image data corresponding to the specified image data ID to the communication terminal device 10 (step S312), and ends this operation.

  On the other hand, in the communication terminal device 10, when the data processing unit 180 receives the image data distributed from the image sharing server device 30 via the network communication unit 110 (step S421), the data processing unit 180 controls the display control unit 150 to The image data is recorded on the storage unit 100 while being displayed on the display unit 140 (step S422), and this operation is terminated.

  Instead of the communication terminal device 10, the image data providing process may be executed by another communication device (not shown) such as a fixed personal computer by individually inputting the terminal ID.

  Further, in the communication terminal device 10 of this operation, an event for which browsing or acquisition of image data is desired is specified based on a user operation on the operation unit 170. When performing, the said event may be specified based on the positional information on the communication terminal device 10, and the event of a check-in state.

  In addition, in the generation of thumbnail image data stored in the image sharing server device 30, each image data may be searched by using only the imaging terminal ID or the in-area terminal ID. That is, in step S304, the server management control unit 340 determines that only the image data in which the imaging terminal ID that matches the extracted own device ID is recorded, or the in-area terminal ID that matches the extracted own device terminal ID exists. Only recorded image data may be read to generate thumbnail image data.

  As described above, the communication terminal device 10 and the image sharing server device 30 according to the present embodiment do not establish a communication line with other communication terminal devices 10 existing in the vicinity of the own device based on the simultaneously transmitted inquiry signal. That is, the existence of the communication terminal device 10 can be recognized without constructing a physical transmission path, and if the terminal ID is not stored (registered) in the content DB 332, the image data is stored in another communication terminal. Since it is not provided to the apparatus 10, it is possible to provide content data only to event attendees or users who are present in the vicinity of the user who captured the image data, and to restrict the provision of the content data.

  Therefore, the communication terminal device 10 and the image sharing server device 30 can protect the privacy without providing content data by an unspecified logarithm user, and can send the content data of the event to users who have not participated in the event. Since it is possible to prevent distribution of unnecessary data such as provision, it is possible to reduce the complexity of user operations when sharing content data, and to appropriately share generated content data.

  Each communication terminal device 10 returns a response signal to the inquiry signal based on whether or not it is in the check-in state, but each communication terminal device 10 receives the user list data that has been checked in. Therefore, when the inquiry signal is received, the response signal may be returned when the inquiry signal from the terminal ID extracted from the received inquiry signal is received.

  In the present embodiment, as content data, image data of a still image is stored in the image sharing server device 30, but it may be a moving image or sound data.

[2] Second Embodiment Next, a second embodiment of the communication system 1 according to the present invention will be described with reference to FIGS.

[2.1] Overview of Communication System First, a second embodiment of the communication system according to the present invention will be described with reference to FIG. FIG. 12 is a diagram for explaining the principle of the communication system in the present embodiment, and is a conceptual diagram showing the relationship between the event holding venue and the user and peripheral terminal detection area.

  In the communication terminal device as the imaging communication terminal device of the first embodiment, the present embodiment receives an inquiry signal instead of detecting the communication terminal device that has received the inquiry signal during the imaging process as an in-area communication terminal device. A feature is that a communication terminal device having a predetermined condition is extracted from the communication terminal devices and stored (registered) in the image sharing server device as an in-area communication terminal device.

  In the present embodiment, except for the above-described features, the configurations of the communication terminal device and the image sharing server device of the present embodiment are the same, and the same components are denoted by the same reference numerals and the description thereof is omitted. To do.

  Specifically, in the present embodiment, each communication terminal device 10 activates an imaging application and executes an imaging process to execute a detailed position at an event venue (hereinafter referred to as an “event venue location”). .), And the camera function of the communication terminal apparatus 10 identifies the imaging direction when imaging the imaging target, and indicates the event holding venue position information corresponding to the event holding venue location and the information indicating the imaging direction (hereinafter referred to as the imaging direction). , “Imaging direction information”) is transmitted to the image sharing server device 30.

  Each communication terminal device 10 is configured to transmit a response signal when receiving an inquiry signal and to transmit location information in the event hosting area of the own device to the image sharing server device 30.

  When the image sharing server device 30 records the image data received by the upload process in the content DB 332, the image sharing direction information, the event ID, the event venue location information, and the in-area terminal ID received together with the image data are the same. Corresponding to the same event ID at the time, the user is included in the imaging target based on the event holding venue location information transmitted from another communication terminal device (that is, the communication terminal device in the area) An extraction process for extracting the in-area communication terminal device is executed.

  The image sharing server device 30 is configured to record the user's communication terminal device 10 included in the imaging target among the in-area communication terminal devices in the content DB 332 so that the image can be shared.

  With this configuration, in the present embodiment, even if the communication terminal device 10 can transmit a response signal to the inquiry signal, that is, the communication terminal device in the area, the communication terminal device 10 If the event venue location does not belong to the imaging area of the imaging communication terminal device, it is not possible to browse and acquire image data formed by imaging the imaging target.

  That is, even if the in-area terminal ID detected by the response signal is provided to the image sharing server device 30 together with the image data, the in-area terminal ID is stored (registered) in the image sharing server device 30 if it does not exist in the imaging area. ) Not to be.

  Therefore, content data such as an image to be imaged captured at an event is provided only to users present in the vicinity of event attendees and users who register content data. It is possible to determine whether or not to provide, that is, to limit the provision.

  As a result, privacy can be protected without providing content data by an unspecified logarithmic user, and distribution of unnecessary data such as providing event content data to users who have not participated in the event accurately. Therefore, it is possible to reduce the complexity of the user operation when sharing the content data, and it is possible to appropriately share the generated content data.

  For example, in the event venue IA as shown in FIG. 12, when the user A captures an imaging target using the camera function of the communication terminal device 10 of the own device as the imaging communication terminal device, the simultaneous transmission is performed using the short-range wireless standard. The inquired signal is acquired from the communication terminal device 10 as the communication terminal device in the area of the user B and the user C existing in the peripheral terminal detection area DA.

  On the other hand, the communication terminal device 10 as the imaging communication terminal device detects the event holding venue position during the imaging process using the GPS function, and stores the event holding venue location information together with the image data to the image sharing server device 30. Send. Similarly, the communication terminal devices 10 of the user B and the user C detect the location within the event venue when receiving an inquiry signal as the intra-area communication terminal device using the GPS function, and the location information in the event venue Is transmitted to the image sharing server device 30.

  By executing the extraction process, the image sharing server device 30 excludes the communication terminal device 10 of the user C from the recording target as the communication terminal device in the area of the content DB 321, and only the communication terminal device 10 of the user B is included in the content DB 321. Store as an in-area communication terminal device.

  That is, in the image sharing server device 30, when the extraction process is executed, it is determined that the user C is outside the imaging area PA based on the position of the user C, the imaging position and the imaging direction by the user A. The communication terminal device 10 of the user C is excluded from the recording target as an in-area communication terminal device.

  In this case, since the user D is in the imaging area but is not identified as an in-area communication terminal device, the user D is not a recording target.

  Therefore, in the case of FIG. 12, when the imaging target is captured by the communication terminal device 10 of the user A, it is stored that only the user C can share the image of the imaging target.

  As described above, in the present embodiment, the image sharing server device 30 is configured so that only the user B who may be included in the image can share the captured image of the captured image. Only the terminal ID of the user B is registered together with the data, and the user B can acquire the image if the terminal ID and the event ID of the user B are specified.

[2.1] Overview of Communication Terminal Device Next, the configuration of the communication terminal device according to the present embodiment will be described with reference to FIGS. 13 and 14. FIG. 13 is a configuration diagram showing the configuration of the communication terminal apparatus 10 of the present embodiment, and FIG. 14 is a diagram showing an example of the data configuration of the image data management table T2 stored in the storage unit 100.

  In addition to the configuration of the first embodiment, the communication terminal device 10 includes a storage unit 400 and a posture detection unit 410 that detects the posture of the communication terminal device. The communication terminal apparatus 10 executes an event participation registration process and an image data acquisition process, and also executes an imaging process while detecting the imaging direction, and information on the imaging direction (hereinafter referred to as “imaging direction information”). It has a data processing unit 480 that executes upload processing for uploading image data to the image sharing server device 30 including optical system information (hereinafter referred to as “optical system information”).

  The above-described units are connected to each other by a bus B, and data transfer is performed between the components.

  The storage unit 400 is configured by a nonvolatile flash memory such as an HDD and a NAND type as in the first embodiment. The storage unit 100 also includes a RAM (Random Access Memory) and a ROM (Read Only Memory) as work areas in the data processing unit 180.

  The storage unit 400 includes at least an application storage unit 101, an image data storage unit 102, and an event information storage unit 104, as in the first embodiment. The storage unit 400 includes a management table storage unit 403 in which an image data management table T2 having a field configuration different from that of the first embodiment is recorded.

For example, in the image data management table T2, as shown in FIG.
(1) Image data ID,
(2) Recording address of the image data,
(3) Condition data indicating imaging conditions of the image data,
(4) imaging position information indicating the imaging location;
(5) Imaging date / time information indicating imaging date / time;
(6) imaging direction information,
(7) In-area terminal ID detected based on the beacon signal
Are stored in association with each other. The elevation angle is detected with the horizontal as “0” degrees.

  Specifically, in the case of the example illustrated in FIG. 12, a terminal corresponding to the communication terminal device 10 possessed by the user B and the user C as the in-area terminal ID when the image is processed by the communication terminal device 10 by the user A. The IDs (MS2 and MS3) are stored in association with each other. Further, FIG. 14 shows that in-area terminal IDs (MS2 to MS12) are stored as in-area terminal IDs for the image data IDs “# 1” to “# 5”, respectively. However, as described above, the communication terminal device 10 having the stored terminal ID is excluded from the intra-area communication terminal device by the extraction process of the image sharing server device 30.

  The posture detection unit 410 is formed of a magnetic sensor that detects weak geomagnetism and an acceleration sensor that detects the direction of gravity. Under the control of the data processing unit 380, when the imaging application is activated, the terminal direction, that is, , Detecting the direction AG (that is, east, west, south, and north) to which the communication terminal device 10 is directed and the elevation angle EA (the angle formed by the horizontal plane and the direction in which the communication terminal device 10 is directed) with respect to the direction AG. The direction AG and the elevation angle EA are stored in the management table storage unit 403 as imaging direction information.

  The data processing unit 480 acquires the imaging direction information provided from the posture detection unit 410 when executing the imaging process, and also stores the imaging direction information stored in the management table storage unit 403 when executing the upload process. And the optical system information of the angle of view and imaging distance (imaging range: distance that can be recognized as an imaging target) in the optical system are transmitted to the image sharing server device 30. The optical system information is stored in advance in an area (not shown) of the storage unit 400.

  On the other hand, when the data processing unit 480 receives the inquiry signal and transmits a response signal based on the inquiry signal to the communication terminal device 10 that has transmitted the inquiry signal, the current position detection unit 120 uses the current position detection unit 120 in the event hosting site. The current position information of the detected event location, that is, the information in the event venue is sent to the image sharing server device 30 as an event ID, a terminal ID of the imaging communication terminal device, and an in-area terminal ID. It is transmitted together with the terminal ID of the machine.

[2.2] Image Sharing Server Device Next, the configuration of the image sharing server device 30 according to the present embodiment will be described with reference to FIG. FIG. 15 is a configuration diagram showing the configuration of the image sharing server device 30 of the present embodiment.

  As shown in FIG. 15, the image sharing server device 30 according to the present embodiment includes a communication control unit 310 and a RAM 320 as in the first embodiment. In addition to the configuration of the first embodiment, the image sharing server device 30 includes a recording device 530 in which a content DB 532 including imaging position information and imaging direction information is stored, and an intra-area communication terminal included in the imaging target A server management control unit 540 that executes an extraction process for extracting only the device is included.

  As in the first embodiment, the recording device 530 is configured by an HDD, and an event DB 331 in which event information is stored in the recording area is constructed. The recording device 530 has a content DB 532 in which information different from that in the first embodiment is recorded.

For example, in the content DB 532, as in the first embodiment,
(1) Event ID
(2) image data corresponding to the event ID,
(3) In-area terminal ID extracted
Are recorded in association with each other.

  In addition to the first embodiment, the server management control unit 540 includes an event ID from the in-area communication terminal device, a terminal ID of the imaging communication terminal device, and a terminal ID of the own device as the in-area terminal ID when executing the upload process. The user receives the location information in the event venue, and the user from the in-area communication terminal device that has received the inquiry signal based on the location information in the event venue and the in-area terminal ID received together with the uploaded image data. An extraction process for extracting the communication terminal device 10 included in the imaging target is executed.

  Specifically, as the extraction process, the server management control unit 540 determines the event holding venue based on the imaging position information, the imaging direction information, and the optical system information transmitted together with the image data and transmitted from the imaging communication terminal device. The imaging area is identified, and it is determined whether or not the event holding venue position information transmitted from the intra-area communication terminal device belongs to the imaging area.

  In particular, when the server management control unit 540 receives image data, the server management control unit 540 performs an extraction process using the location information in the event hosting venue transmitted from the same terminal ID as the terminal ID transmitted together with the image data. At this time, the server management control unit 540 confirms the identity of the event ID and the imaging terminal ID, and specifies whether or not the location information is within the event holding venue that is the target of the extraction process.

[2.3] Operation of Communication System Next, specific processing of the communication terminal apparatus and the image sharing server apparatus executed in the communication system of the present embodiment will be described with reference to FIG. In the present embodiment, the event participation registration process and the image data provision process are the same as those in the first embodiment, and a description thereof will be omitted.

[2.3.1] Operation of Imaging Process and Upload Process Next, operations of the communication terminal apparatus 10 and the image sharing server apparatus 30 in the imaging process and the upload process will be described with reference to FIG. FIG. 16 is a flowchart illustrating the imaging process and upload process of the communication terminal device 10 and the image sharing server device 30 in the present embodiment.

  This operation is an operation executed by the communication terminal device 10 for which the event participation registration process has already been executed, and is an operation executed in the event holding venue in each communication terminal device 10 that is in the check-in state after the event starts. is there.

  Further, it is assumed that the image sharing server device 30 has already recorded a plurality of event information in the event DB 331 and is in a state of waiting for uploading of image data from each communication terminal device 10.

  Then, the communication terminal device (imaging communication terminal device) 10 that executes the imaging process and the upload process has already started the imaging application and is in a check-in state with respect to a predetermined event. It is assumed that a plurality of other communication terminal devices (intra-area communication terminal devices) 10 have already started the imaging application and are in a check-in state with respect to the same event at the event venue.

  In this operation, there are a plurality of communication terminal devices 10 in the peripheral terminal detection area in the actual event venue, but since the processing in each communication terminal device 10 is the same, only one communication terminal device 10 is present. Will be described.

  First, in the communication terminal device 10 as the imaging communication terminal device, the data processing unit 480 detects an operation instruction for performing imaging by the user via the operation unit 170 in the event holding venue after the start of the event (step S50). ), An instruction command for generating image data is output to the imaging / image data generation unit 190, and the imaging / image data generation unit 190 controls the optical system based on the instruction command to capture an imaging target. The image data to be imaged is generated (step S51).

  Next, the data processing unit 480 outputs a recording command command for the generated image data to the imaging / image data generation unit 190, and the imaging / image data generation unit 190 transmits the command to the image data storage unit 102 based on the command. The image data writing process is executed (step S52).

  Next, the data processing unit 480 outputs a command command for transmitting a beacon signal to the short-range wireless communication unit 130, and the short-range wireless communication unit 130 uses the input of the command as a trigger to check in an event. A beacon signal to which an ID is added (that is, a detection inquiry signal of another communication terminal device 10) is transmitted all over the area (step S53).

  At this time, in the communication terminal device 10 as the intra-area communication terminal device, when the data processing unit 480 receives a beacon signal via the short-range wireless communication unit 130 (step S60), the event ID is extracted from the beacon signal. Then, it is determined whether the event ID stored in the event information storage unit 104 is a checked-in event ID (step S61).

  In this process, if the extracted event ID is an event ID stored in the event information storage unit 104 and a checked-in event ID, the data processing unit 480 proceeds to the process of step S62. Otherwise, this operation is terminated.

  Next, the data processing unit 480 adds a response to the received beacon signal via the short-range wireless communication unit 130 that has received the terminal ID of the own device recorded in the storage unit 100 and the event ID in the check-in state. A signal (that is, a response signal to the beacon) is returned (step S62).

  Next, the data processing unit 480 outputs a command command to the current position detection unit 120, and the current position detection unit 120 receives position information corresponding to the current position of the communication terminal device 10 (event holding venue position information). It is detected (step S63).

  Next, the data processing unit 480 transmits to the image sharing server device 30 together with the detected event location information in the event venue, the event ID, the terminal ID of the imaging communication terminal device, and the terminal ID of the own device as the in-area terminal ID. (Step S64), this operation is terminated.

  On the other hand, in the communication terminal device 10 as the imaging communication terminal device, when the short-range wireless communication unit 130 receives a response signal to the beacon transmitted as described above (step S54), the data processing unit 480 The intra-area terminal ID is extracted and acquired from (Step S55), and the image data management table T2 is updated (Step S56).

  Next, the data processing unit 480 controls the network communication unit 110 to execute an image data upload process (step S57). At this time, the data processing unit 480 transmits the image data, the image data management table T2, and the optical system information as data D2 to the image sharing server device 30 by upload processing.

  On the other hand, in the image sharing server device 30, when the server management control unit 540 receives image data or the like via the communication control unit 310 (step S71), the terminal ID and event as the imaging communication terminal device are received from the received data D2. ID, each information of image data management table T2, and optical system information are extracted (step S72).

  Next, the server management control unit 540 determines whether or not data such as location information in the event venue is received from the communication terminal device 10 of the in-area terminal ID included in the image data management table T2 at the same time (step) S73) If it is determined that data such as location information in the event venue has been received, the process proceeds to step S74. If it is determined that data has not been received, the process proceeds directly to step S76. .

  Next, when the server management control unit 540 receives data such as location information in the event venue from the communication terminal device 10 of the in-area terminal ID included in the image data management table T2, the image data is processed in the process of step S76. An imaging area is specified based on the imaging position and imaging direction extracted from the management table T2 (step S74).

  Next, the server management control unit 540 determines the imaging target among the in-area terminal IDs transmitted together with the image data based on the identified imaging area and the received location information within the event venue of each in-area communication terminal device. An extraction process for extracting the estimated terminal ID of the communication terminal device 10 of the user is executed (step S75).

  Next, the server management control unit 540 includes a terminal ID as an imaging communication terminal device, an event ID, image data, and a terminal ID in the image data management table T2 (if an extraction process is being performed, the corresponding terminal ID only) is stored in the corresponding field of the content DB 332 (step S76).

  Next, the server management control unit 540 generates user list data including a terminal ID recorded in association with the event ID and a user name corresponding to the terminal ID, and distributes the data to the communication terminal device 10 ( Step S77), this operation is finished.

  In the communication terminal device 10, when the data processing unit 480 receives the user list data (step S58), the data processing unit 480 controls the display control unit 150 to display the user list data on the display unit 140 while storing the event information. This is stored in the unit 104 (step S59), and this operation is terminated.

  In this way, the image data is stored in the content DB 332, and the process is the same when the image is taken by another communication terminal apparatus 10, and such a series of processes is repeated many times. By being repeated, a large number of image data is accumulated in the content DB 332.

  In FIG. 16, when the update of the image data management table T2 is completed, the data processing unit 480 serving as the imaging communication terminal device uploads, but the timing of the upload process is arbitrary. For example, the image data may be uploaded based on the user's instruction when the user has sufficient time, such as after the end of the event. In this case, when the user performs a predetermined input operation on the operation unit 170 of the communication terminal device 10, the process of step S57 is executed.

  As described above, the communication terminal device 10 and the image sharing server device 30 of the present embodiment can protect privacy without providing content data by an unspecified logarithmic user and do not participate in an event. Since it is possible to prevent unnecessary data distribution such as providing event content data to users, it is possible to reduce the complexity of user operations when sharing content data, and to appropriately generate generated content data Can be shared.

  In the present embodiment, the current location detection unit 120 that uses a GPS signal or a wireless LAN signal also detects the location in the event venue and acquires location information in the event venue. When the event venue is a large outdoor space, the detection method may be switched according to the situation, such as using a GPS signal and, if the event is a small indoor space, using a signal for a wireless LAN.

  Further, in the present embodiment, the server management control unit 540 is transmitted from the communication terminal device 10 as the in-area communication terminal device when image data or the like is uploaded from the communication terminal device 10 as the imaging communication terminal device. The communication terminal device 10 that is estimated to be imaged is extracted based on the image capturing terminal ID and the event venue location information, but each information transmitted from the image capturing communication terminal device and the in-area communication terminal device is extracted. Is stored in the recording device 530, and at the timing of processing, the communication terminal device 10 estimated as the imaging target is extracted for each image data, and is registered in the terminal ID in the image data management table T2.
