Description

  The present invention relates to data sharing technology.

  There is known a technology for enabling a plurality of persons who want to view an image to share the data of the image by storing the data of the image taken by a portable terminal such as a smartphone or a digital camera on the cloud. For example, in a document, data of an image is uploaded to an image management server by one of a plurality of user communication terminals. Then, by enabling each of the plurality of user communication terminals to download the image data uploaded to the image management server, the plurality of users can share the image data.

  However, data of an image uploaded to the image management server may include data of an image that is not related to a person who actually views the image. In this case, the user who wants to view the actual image is forced to select the data related to the user from the uploaded image data.

  It is also common practice to send image data as an email attachment to the terminal of the person requesting to view the image, instead of storing the data on the cloud. However, in this case, a photographer who has performed photography or the like is forced to perform an operation for transmitting an e-mail attached with image data. Further, since there is a limit to the size of the attached file of the e-mail, the photographer will perform the transmission operation many times, and the photographer will perform the operation of selecting the data of the image to be transmitted.

For example, the cloud server 1 and mobile terminals A and B, which are smartphones, are connected to the network 10, which is the Internet, for example. The cloud server 1 may be a physical server or a virtual server. Although the number of portable terminals is two in FIG. 1, the number is not limited.

  FIG. 2 shows a functional block diagram of the cloud server 1. The cloud server 1 includes a communication unit 101, a management unit 103, a classification unit 105, an image data storage unit 107, and a terminal data storage unit 109.

  The communication unit 101 executes a process of receiving data from another device (for example, portable terminals A and B) and a process of transmitting data to the other device. The management unit 103 executes processing based on the data received from the portable terminals A and B and the data stored in the terminal data storage unit 109, and the data of the image stored in the image data storage unit 107 according to the processing result. Are transmitted to the portable terminals A and B. The classification unit 105 executes processing of grouping images based on the data stored in the terminal data storage unit 109.

  FIG. 3 shows an example of the hardware configuration of the portable terminals A and B. The portable terminals A and B include an application processor 301, a memory 303, a camera 305, a display unit 307, an operation input unit 309, an external storage device 311, a baseband processor 313, a wireless communication unit 315, and a position. It has a data acquisition unit 317 and antennas 319 and 321.

  The application processor 301 is connected to the memory 303, the camera 305, the display unit 307, the operation input unit 309, the external storage device 311, and the baseband processor 313. The application processor 301 is a processing device (for example, a CPU (Central Processing Unit)) that executes an application program. The memory 303 is, for example, a random access memory (RAM). The camera 305 performs imaging processing to generate data of an image. The display unit 307 is, for example, a display, and displays data to be displayed. The operation input unit 309 is, for example, a button or a touch panel, and receives an operation by the user. The external storage device 311 is, for example, an SD (Secure Digital) memory card, and can be removed by the user.

  The baseband processor 313 is connected to the application processor 301, the wireless communication unit 315 connected to the antenna 319, and the position data acquisition unit 317 connected to the antenna 321. The baseband processor 313 is, for example, a CPU, and controls the wireless communication unit 315 and the position data acquisition unit 317. The wireless communication unit 315 performs wireless communication. The position data acquisition unit 317 acquires position data by, for example, GPS (Global Positioning System). However, in order to simplify the description, the detailed description of the processing of the baseband processor 313 is omitted below.

  The application processor 301 implements a function as shown in FIG. 4 by executing a program for executing the process in this embodiment. FIG. 4 shows a functional block diagram of the portable terminals A and B. The portable terminals A and B include a management unit 351, a setting data storage unit 353, a terminal data storage unit 355, and an image data storage unit 357. The setting data storage unit 353 and the terminal data storage unit 355 are provided in the memory 303 or the external storage device 311. The image data storage unit 357 is provided in the external storage device 311.

  The management unit 351 controls transmission of image data based on data stored in the setting data storage unit 353 and data stored in the terminal data storage unit 355, and controls transmission of date and time data and position data. Execute processing etc.

  Next, an outline of the present embodiment will be described using FIGS. 5 to 8. Here, the user who operates the portable terminal A (here, the user a) and the user who operates the portable terminal B (here, the user b) goes to the sightseeing spot together, and the user a operates the portable terminal It is assumed that photographing is performed by the camera 305 of A. Then, as shown in FIG. 5, in the data of the image generated at the portable terminal A, the portable terminal A generates date data indicating the date and time of generation of the image and position data indicating the position at which the image is generated. Image File Format) is added as information, and transmitted to the cloud server 1 that manages data of the image of the user a. The cloud server 1 stores the data of the image received from the portable terminal A in the storage area for the user a.

  At a later date, the user b who desires to browse the image photographed at the sightseeing spot by the user a operates the portable terminal B. Here, the operation performed by the user b is only an operation (for example, selection by tap) for specifying the cloud server 1 that manages data of the image of the user a, and does not include complicated operations such as password input. In response to this, as shown in FIG. 6, the portable terminal B transmits a browsing request for requesting browsing of the image of the user a to the cloud server 1 managing data of the image of the user a. In addition, it is assumed that information (for example, an address or a URL (Uniform Resource Locator) or the like) for accessing the cloud server 1 managing data of the image of the user a is registered in the portable terminal B in advance. Further, it is assumed that date and time data indicating a date and time and position data indicating a position on the date and time are periodically acquired by the portable terminal B.

  Then, as shown in FIG. 7, the cloud server 1 having received the browsing request acquires, from the portable terminal B, position data indicating the past position of the portable terminal B and date / time data indicating time at the position. In this acquisition, the user b does not perform any operation (ie, acquisition is performed automatically). Then, the cloud server 1 compares the position data and date data acquired from the portable terminal B with the position data and date data added to the data of the image of the user a, whereby the user a and the user b are together. Identify the data of the image that is presumed to have been taken. Here, image data 701 and image data 702 are specified.

  Then, as shown in FIG. 8, the cloud server 1 transmits the data 701 and 702 of the specified image to the portable terminal B. Thereby, the user b can confirm the image displayed on the display unit 307 of the portable terminal B. Therefore, the user b can browse the data of the image photographed when the user a and the user b are together among the data of the user a without performing a complicated input operation such as selection of the image .

  Next, processing performed by the portable terminals A and B and processing performed by the cloud server 1 will be described with reference to FIGS. 9 to 18.

First, processing in which the portable terminal B acquires date and time data and position data will be described using FIGS. 9 and 10. First, when the user presses the start button, the mobile terminal B is started (FIG. 9: step S1).

The management unit 351 of the portable terminal B outputs a position data acquisition instruction to the position data acquisition unit 317. In response to this, the position data acquisition unit 317 acquires position data from the base station or acquires position data by GPS (step S3). Position data that can be acquired from the base station is position data registered in the base station. The position data acquisition unit 317 can use two different methods. For example, when there is the portable terminal B in the indoor or underground where acquisition of position data by GPS is difficult, the position data may be acquired from the base station.

  The management unit 351 acquires date and time data from, for example, a system clock of the OS (Operating System) (step S5).

  The management unit 351 may execute the process of step S3 and the process of step S5 when a predetermined time has elapsed from the previous execution time. This makes it possible to periodically acquire position data and date and time data.

  The management unit 351 adds the position data acquired in step S3 and the date and time data acquired in step S5 to the terminal data storage unit 355 (step S7).

FIG. 10 shows an example of data stored in the terminal data storage unit 355. In the example of FIG. 10, date and time data and position data indicating the position of the portable terminal B at the date and time represented by the date and time data are accumulated. However, since the memory capacity of the portable terminal B is limited, date and time data and position data added before a certain time may be deleted.

Returning to the description of FIG. 9, when the portable terminal B moves out of the range of the current base station, the position data acquisition unit 317 changes the base station to which the position data is registered (step S9). Then, the process returns to the process of step S3. In addition, when it is in the range of the present base station, the process of step S9 is abbreviate | omitted.

If the above processing is executed, date and time data and position data of the portable terminal B can be accumulated and used for later processing.

  Next, a process of the portable terminal A receiving an input of settings for automatic transmission will be described using FIG.

  First, the operation input unit 309 of the portable terminal A receives an input of settings for automatic transmission from the user (FIG. 11: step S11). The setting for the automatic transmission is a setting as to whether or not the image data is automatically transmitted to the cloud server 1 when the portable terminal A generates the image data.

  The management unit 351 stores setting data, which is data of the setting for which the input has been received in step S11, in the setting data storage unit 353 (step S13). Then the process ends.

  Since the image data can be automatically transmitted if the above processing is performed, the user of the portable terminal A does not have to be conscious of the transmission of the image data. As a result, it is possible to reduce the stress felt by the user due to the operation for uploading the image.

  Next, processing to be performed when the portable terminal A generates image data will be described using FIGS. 12 and 13.

  When the user of the portable terminal A arrives at the imaging spot, the user operates the portable terminal A to activate the camera 305 (FIG. 12: step S31).

  When the camera 305 is activated, the management unit 351 outputs a position data acquisition instruction to the position data acquisition unit 317. In response to this, the position data acquisition unit 317 acquires position data from the base station or acquires position data by GPS (step S33). Further, the management unit 351 acquires date and time data from, for example, a system clock of an OS (Operating System) (step S35).

  The camera 305 executes an imaging process according to the input (for example, a tap of a portion corresponding to the shutter button) received by the operation input unit 309, and generates image data (step S37). The generated image data is output to the management unit 351.

  The management unit 351 adds date and time data and position data to the data of the image generated in step S37 as EXIF information, and stores the data in the image data storage unit 357 (step S39).

  The management unit 351 executes transmission processing (step S41). The process then ends. The transmission process will be described with reference to FIG.

  First, the management unit 351 determines whether the setting for automatic transmission stored in the setting data storage unit 353 indicates "automatic transmission" (FIG. 13: step S51).

  When the setting indicates “automatic transmission” (step S51: Yes route), the management unit 351 outputs the data of the image stored in the image data storage unit 357 in step S39 to the wireless communication unit 315. In response to this, the wireless communication unit 315 transmits the image data (the date and time data and the position data are added to the image data) to the cloud server 1 that manages the image of the user of the portable terminal A. (Step S53). And it returns to the process of the caller.

  On the other hand, when the setting does not indicate “automatic transmission” (step S51: No route), the management unit 351 causes the display unit 307 to display data prompting input of an instruction regarding transmission availability (step S55). The user inputs an instruction on transmission availability via the operation input unit 309 in accordance with the data displayed on the display unit 307.

  The management unit 351 outputs the data of the image stored in the image data storage unit 357 in step S39 to the wireless communication unit 315 when the instruction from the user indicates “send”. In response to this, the wireless communication unit 315 transmits the image data (the date and time data and the position data are added to the image data) to the cloud server 1 that manages the image of the user of the portable terminal A. (Step S57). And it returns to the process of the caller.

  The processes of steps S55 and S57 may be performed after the camera 305 is stopped. In this way, data of a plurality of images generated by the camera 305 can be collectively transmitted to the cloud server 1. In that case, the user may select an image in step S55.

  If the processing as described above is executed, date data and position data can be added to the data of the image generated in the portable terminal A, and can be stored in the cloud server 1.

  Next, processing to be performed when the cloud server 1 receives image data will be described using FIGS. 14 and 15.

  First, the communication unit 101 of the cloud server 1 receives, from the portable terminal A, data of an image to which date data and position data are added (FIG. 14: step S61), and outputs the data to the management unit 103.

  The management unit 103 stores the date and time data and position data added to the data of the image received in step S61 in the terminal data storage unit 109 in association with the image data number (step S63). The data of the image is stored in the image data storage unit 107 in association with the image data number.

  FIG. 15 illustrates an example of data stored in the terminal data storage unit 109. In the example of FIG. 15, an image data number, date and time data, position data, and a group number are stored. However, the group number is not assigned to the data stored in the immediately preceding step S63, and is assigned by the process of step S65.

  Returning to the explanation of FIG. 14, the management unit 103 instructs the classification unit 105 to execute grouping. In response to this, the classification unit 105 performs grouping of images according to a predetermined rule (step S65). The group number stored in the terminal data storage unit 109 is updated based on the processing result of step S65. Then the process ends.

  The predetermined rule is, for example, a plurality of continuously generated images, and (1) the difference between the date and time of the earliest generated image and the date and time of the latest generated image is within 30 minutes And (2) a rule in which a plurality of images satisfying both the condition that the generation positions of the plurality of images fall within a circle with a radius of 100 meters are grouped into the same group. However, it is not necessarily limited to the rules shown here.

  By collectively transmitting the images belonging to the group generated as described above, it becomes possible to transmit a plurality of images presumed to be highly relevant to the portable terminal without omission.

  Next, processing executed when the portable terminal B transmits a browse request to the cloud server 1 will be described using FIGS. 16 to 18.

  First, the wireless communication unit 315 of the mobile terminal B transmits a browsing request for requesting browsing of the image generated by the mobile terminal A to the cloud server 1 managing data of the image generated by the mobile terminal A (see FIG. 16: Step S71). As described above, the user of the portable terminal B is notified in advance by e-mail etc. of information for accessing the cloud server 1 that manages the data of the image generated by the portable terminal A, and the information is portable terminal It shall be registered in B. Therefore, the operation of the user of the portable terminal B is only an operation to specify the cloud server 1 that manages the data of the image generated by the portable terminal A (for example, input of user account information and password). Does not include cumbersome operations. Note that the browsing request may include the identifier of the portable terminal A in order to cope with the case where the cloud server 1 manages image data of a plurality of portable terminals.

  The communication unit 101 of the cloud server 1 that manages data of an image generated by the portable terminal A receives a browsing request from the portable terminal B (step S73). The communication unit 101 outputs the browsing request to the management unit 103.

  The management unit 103 reads out the earliest date and time data among the date and time data of each group related to the portable terminal A (step S75). For example, in the example shown in FIG. 15, the date and time data corresponding to the image data number "DSC_0001", the date and time data corresponding to the image data number "DSC_0002", the date and time data corresponding to the image data number "DSC_0003", and the image data number The date data corresponding to “DSC — 0004”, the date data corresponding to the image data number “DSC — 0006”, and the date data corresponding to the image data number “DSC — 0007” are read out.

  The management unit 103 outputs the read date and time data to the communication unit 101. In response to this, the communication unit 101 transmits the date and time data received from the management unit 103 to the portable terminal B (step S77). FIG. 17 shows an example of data transmitted in step S77. In the example of FIG. 17, the group number and the earliest date and time data in the group of the group number are transmitted. However, the group number may not be included.

  The wireless communication unit 315 of the portable terminal B receives the date and time data from the cloud server 1 that manages the data of the image generated by the portable terminal A (step S79), and outputs the data to the management unit 351.

  The management unit 351 reads, from the terminal data storage unit 355, date and time data closest to the received date and time data and position data corresponding to the date and time data for each group (step S81). The management unit 351 outputs the read date and time data and position data to the wireless communication unit 315.

  The wireless communication unit 315 transmits the date and time data and position data received from the management unit 351 to the cloud server 1 that manages the data of the image generated by the portable terminal A (step S83). FIG. 18 shows an example of data transmitted in step S83. In the example of FIG. 18, the group number, the date and time data closest to the received first date and time data, and the position data corresponding to the date and time data are included.

  The communication unit 101 of the cloud server 1 that manages data of an image generated by the portable terminal A receives date and time data and position data for each group from the portable terminal B (step S85). The communication unit 101 outputs the received date and time data and position data to the management unit 103.

  The management unit 103 determines, for each group, whether or not there is position data indicating a position within a predetermined distance (for example, 500 meters) from the position indicated by the received position data in the terminal data storage unit 109 (step S87) .

  The management unit 103 reads data of an image belonging to a group determined to have position data indicating that the distance from the position indicated by the received position data is within a predetermined distance in the terminal data storage unit 109. (Step S89). The management unit 103 generates data of a preview screen including data of the read image and outputs the data to the communication unit 101.

  The communication unit 101 transmits the data of the preview screen received from the management unit 103 to the portable terminal B (step S91).

  The wireless communication unit 315 of the portable terminal B receives the data of the preview screen from the cloud server 1 and outputs the data to the management unit 351. The management unit 351 causes the display unit 307 to display the data of the preview screen received from the wireless communication unit 315 (step S93).

  As described above, the user of the portable terminal B can view the image of the user of the portable terminal A simply by performing a simple operation. On the other hand, the user of the portable terminal A can release the image only to the appropriate user without specifying the image to be released.

Second Embodiment
Since the memory capacity of the portable terminals A and B is limited, date and time data and position data can not be continuously stored in the terminal data storage unit 355. Therefore, it is conceivable to delete the oldest data in order, but if date and time data and position data are deleted, there is a possibility that the image stored in the cloud server 1 can not be browsed.

  Therefore, in the second embodiment, a method for preventing the inability to view an image while suppressing the memory usage of the portable terminals A and B and the cloud server 1 will be described.

  As a first method, the terminal data storage unit 109 in the cloud server 1 manages data as shown in FIG. In the example of FIG. 19, an image data number, date and time data, position data, a group number, and an ID (IDentifier) of a portable terminal that should receive data of an image are managed. For example, when a browsing request is received from the portable terminal B, for the group numbers 1 and 4, “position data indicating a position where the distance from the position indicated by the received position data is within a predetermined distance is stored in step S87 It is assumed that it is determined that there is a "part 109". In this case, ID-B, which is the ID of the portable terminal B, is stored in the column of the ID of the portable terminal corresponding to the group numbers 1 and 4. Then, when the browsing request is received again from the portable terminal B, even if the date and time data and position data of the portable terminal B are lost, the image having the image data numbers “DSC_0001”, “DSC_0004” and “DSC_0005” Is transmitted to the portable terminal B. This can prevent the portable terminal B from being unable to view the image.

  As a second method, the terminal data storage unit 355 of the portable terminal B manages data as shown in FIG. In the example of FIG. 20, date and time data, position data, and an ID of a cloud server are stored. Here, the ID of the cloud server 1 that is the transmission source of the data of the preview screen is stored in association with the date and time data and position data used when acquiring the data of the preview screen. The data is not deleted for the row in which the ID of the cloud server 1 is stored. This can prevent the portable terminal B from being unable to view the image.

Third Embodiment
In the first embodiment, acquisition of date and time data and position data is performed while the portable terminals A and B are activated. However, there are also users who do not want to always obtain these data during activation of the mobile terminal. In addition, when it is in the situation where it should save the battery and storage area, it is not desirable to keep acquiring these data.

  Therefore, in the third embodiment, acquisition of data is restricted by executing the process as shown in FIG.

  First, the process in which the portable terminal A acquires date and time data and position data will be described. First, when the user presses the start button, the mobile terminal A is started (FIG. 21: step S101).

  The management unit 351 of the portable terminal A determines whether an input of a data acquisition instruction has been received from the user via the operation input unit 309 (step S103). If the input of the data acquisition instruction has not been received (step S103: No route), the process returns to step S103.

  On the other hand, when the input of the data acquisition instruction has been received (step S103: Yes route), the management unit 351 outputs the position data acquisition instruction to the position data acquisition unit 317. In response to this, the position data acquisition unit 317 acquires position data from the base station or acquires position data by GPS (step S107).

  The management unit 351 acquires date and time data from, for example, a system clock of the OS (Operating System) (step S109).

  The management unit 351 may execute the process of step S107 and the process of step S109 when a predetermined time has elapsed from the previous execution time. This makes it possible to periodically acquire position data and date and time data.

  The management unit 351 adds the position data acquired in step S107 and the date and time data acquired in step S109 to the terminal data storage unit 355 (step S111).

  When the portable terminal A moves out of the range of the current base station, the position data acquisition unit 317 changes the base station to which the position data is registered (step S113). Then, the process returns to the process of step S107. In addition, when it is in the range of the present base station, the process of step S113 is abbreviate | omitted.

  The management unit 351 determines whether an input of a data acquisition stop instruction has been received from the user via the operation input unit 309 (step S115). If the input of the data acquisition stop instruction has not been received (step S115: No route), the processing returns to step S107 in order to continue the acquisition.

  On the other hand, when the input of the data acquisition stop instruction is received (step S115: Yes route), the process returns to the process of step S103.

  By executing the above-described processing, it is possible to reflect the user's intention in acquisition of date and time data and position data.

Fourth Embodiment
In the fourth embodiment, a method of more flexibly performing grouping will be described.

  For example, the cloud server 1 receives, from the portable terminal A, data indicating grouping performed by the user. Then, the cloud server 1 stores data as shown in FIG. 22 in the terminal data storage unit 109. In the example of FIG. 22, an image data number, date and time data, position data, a group number, and a group number representing a group designated by the user are stored. Then, the cloud server 1 transmits image data according to the grouping performed by the user.

  In this way, when the user wants to correct the grouping performed by the cloud server 1, grouping can be performed in which the intention of the user is reflected.

  In addition, the cloud server 1 receives data indicating grouping from the portable terminal A, and performs grouping on the grouping performed by the user by further grouping in the same manner as in the first embodiment. Groups may be created. Then, data as shown in FIG. 23 may be stored in the terminal data storage unit 109.
