(First embodiment)
FIG. 1 is a block diagram illustrating the configuration of the storage device 5 and the wireless communication device 15 according to this embodiment.

  First, the storage device 5 will be described.

  The storage device 5 operates by power supplied from the electrically connected host device 10. The storage device 5 has a function of writing and reading data.

  The storage device 5 can also be operated by electric power generated (induced) by electromagnetic induction of the first wireless antenna 20. For example, the storage device 5 can perform communication in accordance with a near field communication standard (NFC) at a frequency such as 13.56 MHz, and can write and read data to and from the wireless communication device 15. That is, the storage device 5 can operate without receiving power from the host device 10.

  The storage device 5 transmits and receives data and commands to and from the host device 10 according to, for example, an SD interface, but other interfaces may be used. The storage device 5 transmits / receives data and commands to / from the wireless communication device 15 along the NFC interface, for example, but other wireless communication interfaces may be used.

  The storage device 5 includes a first wireless antenna 20, a nonvolatile semiconductor memory 25, a first NFC controller 30, a memory controller 35, and a connection terminal 65.

  The nonvolatile semiconductor memory 25 is, for example, a NAND flash memory, but a NOR flash memory, an MRAM (Magnetoresitive Random Access Memory), a PRAM (Phase change Random Access Memory), a ReRAM (Resistive Random). Other nonvolatile semiconductor memories such as Access Memory (resistance change type memory) and FeRAM (Ferroelectric Random Access Memory: ferroelectric memory) may be used. For example, the nonvolatile semiconductor memory 25 may be changed to another nonvolatile memory or the like.

  The nonvolatile semiconductor memory 25 operates when power is supplied from the host device 10 to the storage device 5.

  The memory controller 35 controls the nonvolatile semiconductor memory 25. The memory controller 35 communicates commands and data via the first NFC controller 30. Note that the memory controller 35 may directly communicate with the host device 10 via the connection terminal 65 without going through the first NFC controller 30.

  The memory controller 35 operates when the storage device 5 is supplied with power from the host device 10. On the other hand, when the storage device 5 is supplied with power only from the first wireless antenna 20, the memory controller 35 may not operate.

  When the memory controller 35 receives the first write command CMD, the address ADD, and the data DAT, the memory controller 35 writes the data into the nonvolatile semiconductor memory 25. In addition, when the memory controller 35 receives the first read command CMD and the address ADD, the memory controller 35 reads and outputs data from the nonvolatile semiconductor memory 25.

  Note that the memory controller 35 may write data to the first storage unit 40 when writing to the nonvolatile semiconductor memory 25. The memory controller 35 may write data to the first storage unit 40 when reading data from the nonvolatile semiconductor memory 25.

  The first radio antenna 20 is, for example, a PCB pattern antenna. The frequency band in which the first wireless antenna can operate is set to a predetermined frequency band corresponding to NFC.

Further, the first NFC controller 30 communicates with the host device 10 through the connection terminal 65 for the command CMD, the address ADD, and the data DAT. Further, communication with the memory controller 35 and commands CMD, addresses ADD, and data is performed as necessary.

  The first NFC controller 30 reads data from the first storage unit 40 when receiving the second read command CMD and the address ADD from the wireless communication device 15 via the first wireless antenna 20. Then, the first NFC controller 30 outputs the read data to the wireless communication device 15 via the first wireless antenna 20.

  When the first NFC controller 30 receives the third read command CMD from the wireless communication device 15 via the first wireless antenna 20, the first NFC controller 30 reads data in a predetermined area in the first storage unit 40. Then, the first NFC controller 30 outputs the read data to the wireless communication device 15 via the first wireless antenna 20. That is, when the first NFC controller 30 receives the third read command CMD, the first NFC controller 30 outputs data in a predetermined area from the first storage unit 40 without receiving the address ADD. Note that all data may be output. Note that the second read command CMD and the third read command CMD may be a common command.

  When the first NFC controller 30 receives the second write command CMD, the address ADD, and the data from the wireless communication device 15 via the first wireless antenna 20, the first NFC controller 30 writes the data in the first storage unit 40.

  When the first NFC controller 30 receives the first read command CMD ′ and the address ADD ′ from the wireless communication device 15 or the host device 10, the first NFC controller 30 outputs the first read command CMD and the address ADD to the memory controller 35. The memory controller 35 reads data from the nonvolatile semiconductor memory 25 and outputs it to the first NFC controller 30. Then, the first NFC controller 30 outputs the read data to the wireless communication device 15 or the host device 10. The first read command CMD ′ and the first read command CMD may be any commands that can be recognized by the memory controller 35. Any command can be used as long as the memory controller 35 can recognize the address ADD and the address ADD ′.

  When the first NFC controller 30 receives the first write command CMD ′, the address ADD ′, and data from the wireless communication device 15 or the host device 10, the first NFC controller 30 outputs the first write command CMD, the address ADD, and data to the memory controller 35. To do. The memory controller 35 writes data as data to the nonvolatile semiconductor memory 25. The first write commands CMD ′ and CMD may be any commands as long as they can be recognized by the memory controller 35, similarly to the first read commands CMD and CMD ′.

  Note that the first NFC controller 30 may write data directly into the nonvolatile semiconductor memory 25. The first NFC controller 30 may receive data directly from the nonvolatile semiconductor memory 25.

  Note that when the first NFC controller 30 and the memory controller 35 communicate the command CMD ′, the address ADD ′, and data, the first NFC controller 30 or the memory controller 35 is a part of the data or the data Data converted from the above may be written as data in the first storage unit 40.

  When the first NFC controller 30 receives a related data generation command from the host device 10 or the wireless communication device 15, the first NFC controller 30 reads the data written in the nonvolatile semiconductor memory 25, generates the related data, and generates the first memory. You may write in the part 40.

  The first storage unit 40 is, for example, a nonvolatile memory. The first storage unit 40 stores data according to control by the first NFC controller 30 or the memory controller 35. The data storage in the first storage unit 40 may be temporary. As the first storage unit 40, for example, an EEPROM (Electrically Erasable Programmable Read-Only Memory) is used, but various types of memories can be used in the same manner as the nonvolatile semiconductor memory 25.

  In order to enable operation with the power supplied from the first wireless antenna 20, the nonvolatile memory used for the first storage unit 40 has lower power consumption per unit capacity than the nonvolatile semiconductor memory 25. Is preferable.

Data related to the wireless communication device 15 is recognition ID data of the wireless communication device 15 or the like.

  The voltage detector 45 is electrically connected to the first wireless antenna 20. The voltage detector 45 detects the voltage supplied from the first wireless antenna 20 to the first NFC controller 30. The voltage detector 45 then issues a NFC communication reset command until a predetermined voltage at which the first NFC controller 30 can operate is reached. The first NFC controller 30 does not perform NFC communication while receiving this reset command. This reset command can prevent abnormal start-up / operation of communication by NFC. The voltage detector 45 may output an operable command to the first NFC controller when the voltage reaches a predetermined voltage. The first NFC controller 30 performs NFC communication only when an operable command is received.

When the control unit 85 determines that they do not match (NO in step A4), the first NFC controller 30 performs step A6.

  In addition, when step A4 is OK, for example, when the related data of the storage device 5 is previously stored in the wireless communication device 15 in this application example, or the storage device is stored in the wireless communication device 15 in the application example described later. For example, when 5 related data is stored.

  In step A <b> 5, the control unit 85 of the wireless communication device 15 reads thumbnail data related to the recognition ID from the second storage unit 90. The control unit 85 collates and determines the shooting time data received from the storage device 5 and the shooting time data included in the saved thumbnail data (such as thumbnail image data and shooting time data). When the control unit 85 determines that they match (step A5 OK), the control unit 85 performs step A8. When the control unit 85 determines that they do not match (NO in step A5), the control unit 85 performs step A6.

  If there are a plurality of shooting time data, the determination in step A5 may be OK even if all of them do not match. For example, if a predetermined number of shooting time data matches, the determination in step A5 may be OK. This predetermined number may be set in advance or may be set by the user.

  In step A6, the control unit 85 of the wireless communication device 15 transmits the second read command CMD or the third read command CMD to the storage device 5 by NFC so as to transmit the thumbnail data of the storage device 5.

  In step A7, the first NFC controller 30 of the storage device 5 receives the read command CMD. The first NFC controller 30 reads thumbnail data from the first storage unit 40. The first NFC controller 30 transmits the thumbnail data to the wireless communication device 15 via NFC via the first wireless antenna 20.

  In step A <b> 8, the control unit 85 of the wireless communication device 15 reads the image data of the thumbnail data from the second storage unit 90. Note that the control unit 85 may read the image data of the thumbnail data in step A4 or step A5.

  In step A <b> 9, the control unit 85 of the wireless communication device 15 receives thumbnail data from the storage device 5. The control unit 85 stores the received thumbnail data in the second storage unit 90.

  In step A10, the control unit 85 of the wireless communication device 15 displays the thumbnail data received from the storage device 5, the image data read from the second storage unit 90, or the image data of a composite image using the image data. Output to 95. The display unit 95 displays the input image data.

  FIG. 3 shows, as an example, a case where image data of a composite image in which image data of thumbnail data is arranged is displayed around an image in the storage device 5. The image data of the thumbnail data is trimmed, for example, in a circular shape and has a circular frame. Needless to say, the shape of the image data and the shape of the frame are not limited to a circle, but may be a square or an arbitrary shape.

  FIG. 5 is a diagram schematically illustrating an example of a method for saving thumbnail data in the first storage unit 40 in the storage device 5. The wireless communication device 15 may have a means for displaying the data table on the display unit 95.

  In this storage method, one thumbnail data is stored for one recognition ID. That is, one image data and one shooting time data are stored for one recognition ID. Although this example includes a recognition ID for ease of understanding, a data ID is not always necessary. For example, a recognition ID is not necessary when managing data by a storage address or the like.

  FIG. 6 is a diagram schematically illustrating an example of a method for saving thumbnail data in the second storage unit 90 and the recognition ID in the storage device 5 in the wireless communication device 15. In this storage method, one thumbnail data is stored for the recognition ID and one data ID.

  FIG. 7 is another example of a method for saving thumbnail data in the second storage unit 90 in the wireless communication device 15. This saving method is an example in which the data ID is omitted unlike the saving method of FIG. A plurality of thumbnail data are stored for one recognition ID.

  FIG. 8 is a diagram schematically illustrating an example of a method for updating thumbnail data stored in the storage device 5 (first storage unit 40). The left table shows a list of thumbnail data before update, and the right table shows a list of thumbnail data after update.

  The first NFC controller 30 of the storage device 5 may overwrite the thumbnail data of the data ID with the oldest shooting time when storing new data. That is, in the left table, the oldest thumbnail data is the thumbnail data with the data ID 10. Therefore, the first storage unit 40 overwrites and saves the data of the data ID 10 when storing new thumbnail data.

  FIG. 9 is a diagram schematically illustrating an example of a thumbnail data update method for the wireless communication device 15 (second storage unit 90). The left table shows a list of thumbnail data before update, and the right table shows a list of thumbnail data after update.

  When storing new data, the control unit 85 of the wireless communication device 15 may overwrite the thumbnail data of the data ID with the oldest shooting time in the second storage unit 90. That is, in the left table, the oldest thumbnail data is the thumbnail data with the data ID 10. Therefore, the second storage unit 90 overwrites and saves the data with the data ID 10 when storing new thumbnail data. The updating method shown in FIG. 9 can be used for storing thumbnail data in step A8 in FIG.

(Effect of the first application example)
Thus, according to the present embodiment, the wireless communication device 15 can display the contents of the storage device 5 by holding the storage device 5 over the wireless communication device 15. That is, the user can grasp the contents of the storage device 5 without physically bringing the storage device 5 into contact with the wireless communication device 15 with a cable or the like. That is, the convenience of the user is remarkably improved by omitting the trouble of preparing a new cable and the like and the trouble of physically connecting the storage device 5.

(Modification of the first application example)
The thumbnail data may include an image data ID instead of the shooting time data. The image data ID is an ID uniquely assigned to the image data, for example, a number that can be distinguished from other image data.

(Second application example)
FIG. 10 is a diagram illustrating a second application example of the present embodiment.

  In the second application example, the user selects one or a plurality of image data from the image data of the storage device 5 displayed on the wireless communication device 15. As shown in FIG. 10, a check mark is displayed on the selected thumbnail data. The wireless communication device 15 notifies the storage device 5 that certain thumbnail data has been selected. Upon receiving the notification, the storage device 5 stores flag data corresponding to the selected thumbnail data, for example, in the first storage unit 40.

  FIG. 11 is a flowchart for explaining the second application example.

  In step B1, the user activates App of the wireless communication device 15. App makes the wireless communication device 15 communicable with the storage device 5. The App controls the operation of the wireless communication device 15 in steps B1 to B9.

  In steps B2 and B3, the control unit 85 displays the thumbnail data of the storage device 5 on the display unit 95 of the wireless communication device 15, for example, by the same method as in the first application example.

  In step B <b> 4, the user selects part or all of the thumbnail images displayed on the display unit 95. For example, the user presses the touch panel as the input unit 100 with a finger or a touch pen in accordance with a thumbnail image to be selected. The touch panel that is the input unit 100 outputs information on the pressed position to the control unit 85.

  In step B5, the control unit 85 specifies selected thumbnail data corresponding to the selected thumbnail image from the position information input from the touch panel. The control unit 85 outputs image data in which the image data of the selected thumbnail data is emphasized to the display unit 95. The display unit 95 displays the image data received from the control unit 85. In FIG. 10, the display unit 95 displays an image in which a check mark is added to the image data corresponding to the selected thumbnail data.

  In step B <b> 6, the control unit 85 writes flag data corresponding to the selected thumbnail data in the second storage unit 90.

  In step B7, the control unit 85 outputs the write command CMD, the address ADD, and data including at least flag data to the storage device 5 by NFC.

  In step B8, the first NFC controller 30 of the storage device 5 receives the write command CMD, the address ADD, and data including at least flag data. The first NFC controller 30 writes at least the input flag data in the first storage unit 40.

  In step B9, the user can preferentially perform, for example, the following processing on the image data in the storage device 5 based on the flag data.

  As an example, when the user brings the storage device 5 to a photographer and prints the image data, when displaying a list of image data for selecting an image to be printed, the image data for which flag data is set is Are displayed in a state where they have been selected for printing. As another example, when the user connects the storage device 5 to a terminal capable of displaying image data such as a PC or a tablet, the image data for which flag data is set is displayed at the beginning of the image list. Alternatively, image data for which flag data is set is displayed as a slide show.

  FIG. 12 is a diagram schematically illustrating an example of a method for saving thumbnail data in the second storage unit 90 and the recognition ID in the storage device 5 in the wireless communication device 15 when flag data is included. The flag data includes, for example, a print flag and a priority flag. A print flag and a priority flag can be stored separately for one image data.

  FIG. 13 is a diagram schematically illustrating an example of a method for saving thumbnail data in the first storage unit 40 in the storage device 5 when flag data is included.

(Effect of the second application example)
According to this application example, the user can set a flag in the thumbnail data of the storage device 5 via the wireless communication device 15. By setting the flag, it is possible to change the priority order of printing or display in the storage device 5. That is, user convenience is improved.

(Modification of the second application example)
FIG. 14 is a diagram illustrating a modification of the second application example.

  In the modification of FIG. 14A, the selected image data is displayed in an enlarged manner. By displaying the enlarged image from the other images, the user can confirm the selection and easily confirm the image data.

  In the modification of FIG. 14B, the outline of the selected image data is highlighted. Alternatively, the color of the outline may change. Thereby, the user can confirm his / her selection very easily.

  As described above, the modified example of the second application example can take arbitrary highlighting. For example, the selected image data may be displayed in a square different from the surroundings. Since the selected image data is displayed in a shape different from the surroundings, it is easy for the user to visually recognize.

(Third application example)
FIG. 15 is a flowchart illustrating a third application example of the present embodiment.

  In the third application example, the user can change the thumbnail data displayed for the storage device 5 via the wireless communication device 15.

  In step C1, the user activates App of the wireless communication device 15. App makes the wireless communication device 15 communicable with the storage device 5. The App controls the operation of the wireless communication device 15 in steps C1 to C9.

  In step C <b> 2, the display unit 95 of the wireless communication device 15 displays a setting data change screen for the display order of the storage device 5. The user selects an arbitrary display order setting from the display order setting data change screen. Specifically, for example, the user presses the touch panel that is the input unit 100 in accordance with the setting of the display order to be selected with a finger or a touch pen. The touch panel that is the input unit 100 outputs information on the pressed position to the control unit 85.

  FIG. 16 is an example of a display order setting data change screen in step C2. As an example, the user selects one of (1) new date order, (2) old date order, and (3) user settings.

  In step C <b> 3, the controller 85 specifies display order setting data corresponding to the selection from the position information input from the touch panel.

  In step C4, the control unit 85 outputs the data including the write command CMD, the address ADD, and at least display order setting data to the storage device 5 by NFC. Note that the write command CMD at this time may use another write command CMD different from the normal write command CMD.

  In Step C5, the first NFC controller 30 receives data including a write command CMD, an address ADD, and at least display order setting data. The first NFC controller 30 writes display order setting data in the first storage unit 40.

  In step C <b> 6, the storage device 5 stands by until power is supplied from the host device 10.

  In step C <b> 7, after supplying power from the host device 10, the memory controller 35 reads display order setting data from the first storage unit 40.

  In step C <b> 8, the memory controller 35 collates and determines the reading display order setting data and the old reading display order setting data stored in the nonvolatile semiconductor memory 25 or the first storage unit 40.

  If the old setting data matches the new setting data, the thumbnail data stored in the first storage unit 40 is not updated (step C8 OK). On the other hand, if the old setting data and the new setting data do not match, the process flow proceeds to step C9 (step C8 NG).

  In step C9, the memory controller 35 writes thumbnail data in the first storage unit 40 based on the new setting data. Note that the memory controller 35 may write the data stored in the nonvolatile semiconductor memory 25 or may write the calculation result of the data stored in the nonvolatile semiconductor memory 25.

(Effect of third application example)
According to this application example, the content of the thumbnail data in the storage device 5 can be changed to any content of the user through the wireless communication device 15. The user interface can be improved along with the change of the thumbnail data to be displayed. Furthermore, since the wireless communication device 15 includes an output unit, for example, a display, the user can change the display order setting data with good operability.

(Modification of third application example)
In the above description, in step C9, the example in which the memory controller 35 directly writes in the first storage unit 40 has been described. However, the present invention is not limited to this. That is, the memory controller 35 may write to the first storage unit 40 via the first NFC controller 30.

  In steps C6 to C8 described above, the memory controller 35 compares the old setting data with the new setting data. As a modification, the first NFC controller 30 can perform comparison. In this modification, the first NFC controller 30 can make a comparison without the supply of power from the host device 10. In this modification as well, the rewriting of the thumbnail data in the first storage unit 40 in step C9 is performed after power is supplied to the storage device 5.

(Fourth application example)
FIG. 17 is a diagram illustrating a fourth application example of the present embodiment.

  As illustrated in FIG. 17, when the storage device 5 enters the field of view of the photographing unit 110 of the wireless communication device 15, the wireless communication device 15 displays image data included in the thumbnail data of the storage device 5.

  In step D2, the photographing unit 110 photographs the storage device 5 and the code 120 provided in the storage device 5 by the user. The photographing unit 110 outputs photographing data (first image data) to the control unit 85.

  In step D3, the control unit 85 of the wireless communication device 15 detects the code 120 from the shooting data.

  In step D <b> 4, the control unit 85 of the wireless communication device 15 obtains information included in the code 120 by decoding (extracting) the code 120. The information included in the code 120 is, for example, a recognition ID of the storage device 5.

  In step D <b> 5, the control unit 85 of the wireless communication device 15 reads the stored recognition ID from the second storage unit 90. Thereafter, the control unit 85 collates and determines the recognition ID already stored and the recognition ID acquired by decoding.

  When the control unit 85 determines that they match (step D5 OK), the control unit 85 performs step D6. When the control unit 85 determines that they do not match (NO in step D5), the control unit 85 performs step D7.

  In addition, when step D5 is OK, for example, when the related data of the storage device 5 is previously stored in the wireless communication device 15 in this application example, or the storage device is stored in the wireless communication device 15 in the application example described later. For example, when 5 related data is stored.

  In step D <b> 6, the control unit 85 of the wireless communication device 15 reads image data included in the thumbnail data related to the matching recognition ID from the second storage unit 90. The control unit 85 generates composite image data obtained by combining the image data acquired from the image capturing unit 110 and the read image data. The control unit 85 outputs the composite image data to the display unit 95.

  In step D <b> 7, the control unit 85 of the wireless communication device 15 outputs the shooting data acquired from the shooting unit 110 to the display unit 95.

  In step D8, the display unit 95 of the wireless communication device 15 displays the input image data or composite image data.

(Effect of the fourth application example)
According to this application example, the user can check the image data in the storage device 5 even from a long distance.

(First modification of the fourth application example)
In step D7 in the above description, the control unit 85 of the wireless communication device 15 outputs the shooting data of the shooting unit 110 to the display unit 95 as it is. As a modification, for example, the control unit 85 generates composite image data obtained by combining image data indicating that the information regarding the storage device 5 is not stored in the wireless communication device 15 and the shooting data acquired by the shooting unit 110. May be. The control unit 85 outputs the composite image data to the display unit 95.

  In this case, the user can explicitly recognize that the information regarding the storage device 5 is not stored in the wireless communication device 15. That is, user convenience is improved.

(Second modification of the fourth application example)
FIG. 19 is a diagram illustrating a second modification of the fourth application example of the present embodiment.

  As shown in FIG. 19, when a plurality of storage devices 5 enter the field of view of the photographing unit 110 of the wireless communication device 15, the wireless communication device 15 displays the image data included in the thumbnail data of the storage device 5.

  The user can confirm the contents of the plurality of storage devices 5 at a time, which improves convenience.

  Although FIG. 19 shows the case where there are two storage devices 5, the number is not limited to two, and an arbitrary number of storage devices 5 may be displayed. Furthermore, when the number of storage devices 5 is too large and the display becomes complicated, the wireless communication device 15 does not display thumbnail data of all the storage devices 5 but displays thumbnail data of some of the storage devices 5. It may be displayed.

(Third modification of the fourth application example)
FIG. 20 is a diagram illustrating a third modification of the fourth application example of the present embodiment.

  As shown in FIG. 20, when displaying the thumbnail data of the storage device 5, the remaining capacity may be displayed simultaneously. The user can check the remaining capacity of the plurality of storage devices 5, and convenience is improved. Specifically, for example, when the user wants to carry a storage device 5 that can newly record more photographs during travel, according to this application example, the user can easily select a storage device 5 with a large free space. Can do.

(Fifth application example)
FIG. 21 is a flowchart showing a fifth application example of this embodiment.

  In this application example, the wireless communication device 15 stores the image data in the storage device 5 in advance via the host device 10 and the server 13. The wireless communication device 15 can display the thumbnail image data of the storage device 5 at high speed using NFC or a camera. Hereinafter, it demonstrates along a flowchart.

  In step E <b> 1, the user connects the storage device 5 to the host device 10. The storage device 5 is connected to the host device 10 via the connection terminal 65. The storage device 5 is connected to the host device 10 according to the USB standard, for example.

  In step E2, the host device 10 is connected to the server via, for example, a network. The host device 10 includes user information (for example, user ID, user ID and password, ID of the wireless communication device 15, ID of the wireless communication device and password), storage device recognition ID, thumbnail data (thumbnail image data, shooting time data). Etc.) to the server 13. Note that data may be transmitted to the server 13 via the wireless communication device 15 instead of the host device 10.

  In step E3, the server 13 stores the recognition ID and thumbnail data of the storage device based on the received user information.

  In step E4, the user activates App of the wireless communication device 15. The App controls the operation of the wireless communication device 15 in steps E1 to E11.

  In step E5, the control unit 85 connects to the server 13 via the wireless communication unit 105 by wireless communication or the like. The wireless communication device 15 transmits user information to the server 13. The wireless communication device 15 may be connected to the server 13 via another communication terminal or a network, or may be connected to the server 13 via a so-called Internet.

  In step E6, the server 13 authenticates the received user information. Based on the user information, the server 13 transmits the recognition ID and thumbnail data of the storage device previously saved based on the user information to the wireless communication device 15.

  In step E <b> 7, the wireless communication unit 105 of the wireless communication device 15 receives the recognition ID and thumbnail data of the storage device 5 from the server 13. The wireless communication unit 105 outputs the received information to the control unit 85. The control unit 85 outputs the input information to the second storage unit 90. The 2nd memory | storage part 90 memorize | stores these input information.

  In step E8, the control unit 85 of the wireless communication device 15 transmits a read command or the like by NFC to the storage device 5 so as to transmit the recognition ID and shooting time data of the storage device 5.

  In step E <b> 9, the first NFC controller 30 reads the recognition ID of the storage device 5 from the first storage unit 40. The first NFC controller 30 transmits to the wireless communication device 15 by NFC.

  In step E <b> 10, the control unit 85 of the wireless communication device 15 reads the recognition ID stored from the second storage unit 90. The control unit 85 collates and determines the received recognition ID of the storage device 5 and the stored recognition ID. When the control unit 85 determines that they match (step E10 OK), the control unit 85 performs step E12. When the control unit 85 determines that they do not match (NO in step E10), the control unit 85 and the like perform step E11.

  In step E11, the wireless communication device 15 acquires the thumbnail data of the storage device 5 by the same processing as in steps A2 to A9 of the first application example.

  In step E <b> 12, the control unit 85 of the wireless communication device 15 outputs thumbnail image data included in the thumbnail data or a composite image using the thumbnail image data to the display unit 95. The display unit 95 displays the input image data.

(Effect of the fifth application example)
According to this application example, the wireless communication device 15 can acquire the image data of the storage device 5 from the server 13 in advance without acquiring the image data from the storage device 5. Thereby, the wireless communication apparatus 15 can display image data at high speed.

(First modification of the fifth application example)
Steps E7 and E8 need not be performed close in time. That is, in step E7, the wireless communication device 15 acquires an image in advance. Thereafter, step E8 may be executed after a certain time, for example, by changing the day.

(Second modification of the fifth application example)
In this application example, not the thumbnail data (thumbnail image data, shooting time data, etc.) but image data and shooting time data stored in the storage device 5 are transmitted and received between the wireless communication device 15, the host device 10, and the server 13. It doesn't matter.

  In this application example, communication from the storage device 5 to the host device 10 (step E1), communication from the host device 10 to the server 13 (step E2), and communication between the server 13 and the wireless communication device 15 (steps E5 to E7). These communications can be performed at a higher speed than NFC.

  Therefore, it is possible to transmit / receive original image data having a larger data capacity and a larger number of pixels than thumbnail image data, that is, high-quality original image data. A clear image can be displayed on the display unit 95 by transmitting and receiving the original image.

(Third modification of the fifth application example)
FIG. 22 is a flowchart of a third modification of the fifth application example. Steps F1 to F7 are the same as in FIG.

That is, when the storage device 5 is imaged by the imaging unit 110 of the wireless communication device 15, image data included in the thumbnail data of the storage device 5 is displayed on the display unit 95.

  Specifically, in step F8, the processes of steps D1 to D8 in FIG. 18 are performed. The display unit 95 displays an image including information on thumbnail image data included in the thumbnail data of the storage device 5.

  Note that, in this modified example as well, the original image of the storage device 5 may be transmitted / received instead of the thumbnail data as in the second modified example.

FIG. 23 is a flowchart illustrating a sixth application example.

  In this application example, the wireless communication device 15 displays image data included in the thumbnail data stored in the storage device 5 in advance. The user inputs flag data. The wireless communication device 15 connects to the server 13 and transmits the flag data. For example, the server 13 issues a print instruction to the print shop based on the received flag data. That is, the user can print the image stored in the storage device 5 by the terminal device of the wireless communication device 15.

  In step G1, the server 13 stores the thumbnail data of the storage device 5 by the method of the fifth application example (steps E1 to E3 in FIG. 21).

  In step G2, the wireless communication device 15 performs the method (NFC) of the first application example (steps A6, A7, A9 in FIG. 4) or the method (steps E4 to E7 in FIG. 21) ( Via the server 13, the thumbnail data of the storage device 5 is stored.

  In step G3, the wireless communication device 15 acquires flag data by the method of the second application example (steps B3 to B6 in FIG. 11).

  In step G <b> 4, the control unit 85 of the wireless communication device 15 connects to the server 13 via the wireless communication unit 105. Further, the control unit 85 transmits flag data to the server 13.

  In step G5, the server 13 receives the flag data and performs, for example, the following processing.

  For example, the server 13 transmits the received flag data and image data to, for example, a photographer. The photographer then makes a print reservation for the photo based on the flag data. Alternatively, the image data transmitted from the wireless communication device 15 is printed.

  For example, the server 13 allows the image data to be viewed from another user based on the received flag data. Or send it to a specific user by e-mail.

(Effect of the sixth application example)
The user can make a print reservation for a photo or print a photo by operating the wireless communication device 15. That is, user convenience is significantly improved.

(Seventh application example)
FIG. 24 is a flowchart showing a seventh application example.

  In this application example, the wireless communication device 15 acquires the thumbnail data of the storage device 5 from the server 13. By acquiring the thumbnail data from the server 13, it is possible to display the thumbnail image data of the storage device 5 at high speed.

  Hereinafter, it demonstrates along a flowchart.

  In step H1, the server 13 stores the thumbnail data of the storage device 5 by the method of the fifth application example (steps E1 to E3 in FIG. 21). In this application example, the thumbnail data of the storage device 5 is stored based on the recognition ID of the storage device 5. In this application example, user information is not necessarily required.

  In step H2, the user activates App of the wireless communication device 15. The App controls the operation of the wireless communication device 15 in steps H2 to H9.

  In step H3, the control unit 85 of the wireless communication device 15 transmits the second read command CMD or the third read command CMD to the storage device 5 by NFC so as to transmit the recognition ID and shooting time data of the storage device 5. To do. Note that the control unit 85 may transmit the address ADD together when necessary.

  In step H4, the first NFC controller 30 of the storage device 5 receives the read command CMD. The first NFC controller 30 reads the recognition ID and shooting time data from the first storage unit 40. The first NFC controller 30 transmits the data read by NFC to the wireless communication device 15. The shooting time data may be one or a plurality of data for each image.

  In step H5, the control unit 85 of the wireless communication device 15 receives the recognition ID and shooting time data. The control unit 85 reads the recognition ID and shooting time data stored from the second storage unit 90. The control unit 85 collates and determines the received recognition ID and shooting time data of the storage device 5 with the stored recognition ID and shooting time data. When the control unit 85 determines that they match (step H5 OK), the control unit 85 and the like perform step H9. When the control unit 85 determines that they do not match (NO in step H5), the control unit 85 performs step H6. Note that the processing in step H5 may be the same as the processing in steps A4 and A5 of the first application example.

  In step H <b> 6, the control unit 85 connects to the server 13 through wireless communication or the like via the wireless communication unit 105. The wireless communication device 15 transmits the recognition ID information and the like of the storage device 5 to the server 13. In addition, instead of the recognition ID of the storage device 5, user information, the recognition ID of the wireless communication device 15, or the like may be used.

  In step H <b> 7, the server 13 receives the recognition ID information of the storage device 5. The server 13 transmits the thumbnail data of the storage device 5 stored based on the recognition ID of the storage device 5 to the wireless communication device 15.

  In step H <b> 8, the wireless communication unit 105 of the wireless communication device 15 receives the thumbnail data of the storage device 5 from the server 13. The wireless communication unit 105 outputs the received information to the control unit 85. The control unit 85 outputs the input information to the second storage unit 90. The 2nd memory | storage part 90 memorize | stores these input information.

  In step H9, the thumbnail image data included in the thumbnail data or the image data of the composite image using the thumbnail image data is output to the display unit 95. The display unit 95 displays the input image data. The display unit 95 displays the input image data.

(Effect of the seventh application example)
As in the fifth application example, the user can check the data in the storage device 5 at high speed by using the wireless communication device 15. Further, unlike the fifth application example, this application example can download only the necessary thumbnail data of the storage device 5, so there is no need to store extra data in the wireless communication device 15. That is, it is possible to effectively use the convenience of the user and the data storage capacity of the wireless communication device 15.

(First modification of the seventh application example)
In this application example, as in the fifth application example, not the thumbnail data (thumbnail image data, shooting time data, etc.) but the image data and shooting time data stored in the storage device 5 are transferred to the wireless communication device 15, Transmission / reception may be performed between the host apparatus 10 and the server 13.

  In this application example, communication from the storage device 5 to the host device 10 (step H1), communication from the host device 10 to the server 13 (step H1), and communication between the server 13 and the wireless communication device 15 (steps H6 to H8). These communications can be performed at a higher speed than NFC.

  Therefore, it is possible to transmit / receive original image data having a larger data capacity and a larger number of pixels than thumbnail image data, that is, high-quality original image data. A clear image can be displayed on the display unit 95 by transmitting and receiving the original image.

(Second modification of the fifth application example)
FIG. 25 is a flowchart of a second modification of the seventh application example. Steps J1 and J2 may be the same processing as steps H1 and H2 in FIG.

  In step J3, the photographing unit 110 photographs the storage device 5 and the code 120 provided in the storage device 5 by the user. The photographing unit 110 outputs photographing data (first image data) to the control unit 85.

  In step J4, the control unit 85 of the wireless communication device 15 detects the code 120 from the shooting data.

  In Step J <b> 5, the control unit 85 of the wireless communication device 15 acquires information included in the code 120 by decoding (extracting) the code 120. The information included in the code 120 is, for example, a recognition ID of the storage device 5.

  In step J <b> 6, the control unit 85 of the wireless communication device 15 reads the stored recognition ID from the second storage unit 90. Thereafter, the control unit 85 collates and determines the stored recognition ID and the recognition ID acquired by decoding.

  When the control unit 85 determines that they match (step J6 OK), the control unit 85 performs step J10. When the control unit 85 determines that they do not match (NO in step J6), the control unit 85 performs step J7.

  In step J <b> 7, the control unit 85 connects to the server 13 by wireless communication or the like via the wireless communication unit 105. The wireless communication device 15 transmits the recognition ID information and the like of the storage device 5 to the server 13. In addition, instead of the recognition ID of the storage device 5, user information, the recognition ID of the wireless communication device 15, or the like may be used.

  In step J8, the server 13 receives the received recognition ID information of the storage device 5. The server 13 transmits the thumbnail data of the storage device stored based on the recognition ID of the storage device 5 to the wireless communication device 15.

  In step J <b> 9, the wireless communication unit 105 of the wireless communication device 15 receives the thumbnail data of the storage device 5 from the server 13. The wireless communication unit 105 outputs the received information to the control unit 85. The control unit 85 outputs the input information to the second storage unit 90. The 2nd memory | storage part 90 memorize | stores these input information.

  In step J <b> 10, when step J <b> 6 is YES, the control unit 85 of the wireless communication device 15 reads thumbnail image data included in the thumbnail data regarding the matching recognition ID from the second storage unit 90. The control unit 85 generates composite image data obtained by combining the image acquired from the imaging unit 110 and the read image data. The control unit 85 outputs the composite image data to the display unit 95, and the display unit 95 displays the composite image data.

  When step J6 is NO, the control unit 85 of the wireless communication device 15 combines the composite image data obtained by combining the thumbnail image data included in the thumbnail data acquired from the server 13 and the shooting data acquired from the shooting unit 110. Generate. The control unit 85 outputs the composite image data to the display unit 95, and the display unit 95 displays the composite image data.

  In this modification, it is possible to display the image data stored in the storage device 5 from a distance away from the storage device 5 regardless of NFC.

  Note that in this modified example as well, the original image in the storage device 5 may be transmitted / received instead of the thumbnail data as in the first modified example.

(Eighth application example)
26 and 27 are diagrams illustrating an eighth application example. In FIG. 27, the description of the pattern of the code 120 is omitted. The arbitrary code 120 described with reference to FIG. 2 can be used.

  As shown in FIG. 26, a list of information stored in the storage device 5 is displayed on the display unit 95 of the wireless communication device 15. The user selects an arbitrary storage device 5 from the list. Information about the selected storage device 5 is highlighted.

  Specifically, referring to FIG. 26, the display unit 95 of the wireless communication device 15 includes two storage devices (comments related to the storage device 5 include “travel photos” and “landscape photos”, respectively). The storage device 5 for “travel photos” is selected and highlighted by the user.

  As illustrated in FIG. 27, the photographing unit 110 photographs an arbitrary storage device 5. Then, an image in which the storage device 5 of “travel photograph” selected in FIG. 26 is highlighted is displayed on the display unit 95. Specifically, in FIG. 27, five storage devices 5 are placed. The storage device 5 in the center is the storage device 5 for “travel photos”, and the outline of the storage device 5 is highlighted on the display unit 95.

  That is, according to this application example, the user can search for the selected storage device 5 by selecting the arbitrary storage device 5 with the wireless communication device 15 and shooting the arbitrary storage device 5 with the imaging unit 110. .

  FIG. 28 is a flowchart for explaining the eighth application example.

  Hereinafter, it demonstrates along a flowchart.

  In step K1, for example, the second storage unit 90 of the wireless communication device 15 stores the recognition ID and thumbnail image of the storage device 5 by any method of the application example described above. Regardless of the application example described above, the second storage unit 90 stores the recognition ID of the storage device 5 by direct or indirect connection via the other connection terminal 65 or the first wireless antenna 20. Also good.

  In step K2, the user activates App of the wireless communication device 15. The App controls the operation of the wireless communication device 15 in steps K2 to K12.

  In step K <b> 3, the control unit 85 reads the recognition ID, thumbnail data, and the like of the storage device 5 that are already stored from the second storage unit 90. The control unit 85 generates composite image data of the list of the storage device 5 illustrated in FIG. 26 from the read data such as the recognition ID and outputs the combined image data to the display unit 95. The display unit 95 displays the composite image data.

  In step K4, for example, the user presses the touch panel as the input unit 100 with a finger or a touch pen in accordance with the storage device 5 to be selected. The touch panel which is the input unit 100 outputs information on the pressed position to the control unit 85.

  In Step K5, the control unit 85 specifies the selected storage device 5 from the position information input from the touch panel. The control unit 85 stores the recognition ID corresponding to the selected storage device 5 in the cache memory in the control unit 85 or the second storage unit 90.

  In step K <b> 6, the photographing unit 110 photographs an arbitrary storage device 5. In FIG. 27, the photographing unit 110 photographs five storage devices 5. Then, the imaging unit 110 outputs the imaging data (first image data) to the control unit 85.

  In step K7, the control unit 85 of the wireless communication device 15 detects the code 120 from the captured data. In the example of FIG. 27, the control unit 85 detects five codes 120.

  In step K8, the control unit 85 of the wireless communication device 15 decodes (extracts) the code 120 to obtain the recognition ID of the storage device 5 included in the code 120.

  In step K9, the control unit 85 of the wireless communication device 15 reads the saved recognition ID from the second storage unit 90 or the cache memory. After that, the control unit 85 collates and determines the saved recognition ID and the decoded and read recognition ID.

  If the control unit 85 determines that they match (step K9 OK), the control unit 85 performs step K10. When the control unit 85 determines that they do not match (NO in step K9), the control unit 85 performs step K11.

  In step K10, the control unit 85 of the wireless communication device 15 specifies the storage device 5 'corresponding to the matching recognition ID. The control unit 85 generates composite image data in which a portion corresponding to the storage device 5 ′ is highlighted based on the photographing data, and outputs it to the display unit 95. In addition, although the example which emphasized the outline of the memory | storage device 5 is shown in FIG. 27, the highlighting method is arbitrary. For example, the color of the storage device 5 can be changed, it can be emphasized with an arrow icon, or can be highlighted by any method. Note that the storage device 5 that does not correspond is displayed as it is without being particularly highlighted.

  In step K11, the control unit 85 outputs the captured data as it is to the display unit 95.

  In step K12, the display unit 95 displays the shooting data or the composite image data input from the control unit 85.

(Effect of the eighth application example)
According to this application example, the storage device 5 stored in the wireless communication device 15 in the past can be highlighted through the imaging unit 110 and the display unit 95 of the wireless communication device 15. That is, the user can search for the selected storage device 5 without confirming the contents of the storage device 5. That is, user convenience is significantly improved.

(Modification of the eighth application example)
In step K <b> 11 of the above description, the control unit 85 of the wireless communication device 15 outputs the shooting data of the shooting unit 110 to the display unit 95 as it is. As a modification, for example, the control unit 85 generates composite image data obtained by combining image data indicating that the information regarding the storage device 5 is not stored in the wireless communication device 15 and the shooting data acquired by the shooting unit 110. May be. The control unit 85 outputs the composite image data to the display unit 95.

  In this case, the user can recognize that the storage device 5 that has been explicitly selected has not been shot by the shooting unit 110 of the wireless communication device 15. That is, user convenience is improved.

  One application example of the control method of the wireless communication device 15 according to the present embodiment is summarized as follows, for example.

  The control method of the wireless communication device stores the first information displayed on the outer surface of the storage device in the storage unit, and includes the first information in the imaging unit when the imaging unit captures the first information. Generating first image data, causing the control unit to extract the first information from the first image data, collating with the first information stored in a storage unit, and storing the first image data out of the first image data; Second image data in which a region corresponding to the apparatus is highlighted is generated, and the display unit displays the second image data.

  Further, the control method of the wireless communication device may cause the second information in the second storage device to be captured at the same time when the first information is captured, and the portion corresponding to the second storage device when the second image data is generated. Generates the second image data which is the first image data.

(Ninth application example)
29 to 32 are diagrams illustrating a ninth application example.

  As shown in FIG. 29, a field for inputting a search keyword is displayed on the display unit 95 of the wireless communication device 15. The user inputs arbitrary search keywords such as a file name and update time.

  Specifically, referring to FIG. 29, the display unit 95 of the wireless communication device 15 displays a file name input field in the upper part and an update time input field in the lower part. The user inputs “Presentation” in the file name input field, and inputs 2015.1.1 to 2015.1.15 in the update time field. Thereafter, the user presses a search start button.

  Subsequently, as illustrated in FIG. 30, the user photographs an arbitrary storage device 5 using the photographing unit 110 of the wireless communication device 15. Then, an image in which the storage device 5 storing the file matched with the search condition designated in FIG. 29 is highlighted is displayed on the display unit 95.

  Specifically, in FIG. 30, five storage devices 5 are placed. Among them, the central storage device 5 and the upper right storage device 5 are storage devices 5 that store files corresponding to the search conditions. In the display unit 95, the outline of the corresponding storage device 5 is highlighted.

  That is, according to this application example, the user designates an arbitrary search keyword with the wireless communication device 15 and shoots the arbitrary storage device 5 with the imaging unit 110, thereby storing a file corresponding to the selected search keyword. Storage device 5 can be searched.

  FIG. 31 is a flowchart for explaining the ninth application example.

  Hereinafter, it demonstrates along a flowchart. In addition, about the part similar to the 8th application example, description is abbreviate | omitted suitably.

  In Step L1, for example, the second storage unit 90 of the wireless communication device 15 stores the recognition ID and the thumbnail image of the storage device 5 by any method of the application example described above. Regardless of the application example described above, the second storage unit 90 stores the recognition ID of the storage device 5 by direct or indirect connection via the other connection terminal 65 or the first wireless antenna 20. Also good.

  FIG. 32 is a table schematically showing an example of a method in which the second storage unit 90 stores information in the storage device 5.

  In step L1 of FIG. 32, the title corresponding to the recognition ID, the entire capacity of the storage device 5 and the free space are stored in correspondence with the recognition ID of the storage device 5. One or more file names are stored for each recognition ID. Corresponding to each file name, property data such as file creation date, file update date, and file size are stored.

  In step L2, the user activates App of the wireless communication device 15. The App controls the operation of the wireless communication device 15 in steps L2 to L11.

  In step L3, the control unit 85 causes the display unit 95 to display a screen including a column for inputting a user search keyword. The user inputs data on the touch panel as the input unit 100 with a finger or a touch pen in accordance with the storage device 5 to be searched. The input unit 100 outputs the input search keyword information to the control unit 85.

  In step L4, the control unit 85 reads information of the storage device 5 shown in FIG. 32 from the second storage unit 90. The control unit 85 compares the read information of the storage device 5 with the search keyword information, and specifies the storage device 5 that stores the file that matches the search condition.

  In the example of FIG. 29, the search keyword information is “file name: presentation, update time: 2015.1.1 to 2015.1.15”. In the example of FIG. 32, the search keyword information matches “Presentation 1.pptx” included in the recognition ID 01111 and “America presentation.pptx” included in the recognition ID 02222. That is, the control unit 85 specifies “ID01111” and “ID02222” as the recognition IDs of the storage device 5 that match the search keyword information.

  In the following steps L5 to L11, processing similar to steps K6 to K12 of the eighth application example is performed.

  The composite image data displayed on the display unit 95 in step L11 is image data in which the recognition IDs “ID01111” and “ID02222” of the storage device 5 are highlighted in the examples of FIGS. That is, as shown in FIG. 30, two corresponding storage devices 5 are highlighted.

  If a file matching the search keyword is not stored in any storage device 5, the control unit 85 outputs an error display to that effect to the display unit 95 at step L4, and performs processing. You may end. Alternatively, the control unit 85 may determine that the branch of step L8 is NG, and the control unit 85 may cause the display unit 95 to display the shooting data as it is.

(Effect of the ninth application example)
According to this application example, the file information stored in the storage device 5 stored in the wireless communication device 15 in the past can be searched via the wireless communication device 15. That is, the user can search for a desired file without checking the data stored in the storage device 5 one by one. That is, user convenience is significantly improved.

(First modification of the ninth application example)
The input of the search keyword from the user shown in FIG. 29 is not limited to the above example. For example, the search may be performed using file creation date, file extension, file size, file type (video, audio, image, text, binary, etc.), and arbitrary information.

  Further, as described above, the user may input a voice without inputting from the input unit 100.

(Second modification of the ninth application example)
FIG. 33 is a flowchart illustrating a second modification of the ninth application example. The second modification is different from the flowchart shown in FIG. 31 in the contents of the processing after step M4.

  That is, in the flowchart of FIG. 31, the control unit 85 searches for the storage device 5 that matches the search keyword first. Thereafter, the control unit 85 searches the storage device 5 that matches the image data captured by the image capturing unit 110.

  On the other hand, in the flowchart of FIG. 33, the control unit 85 first identifies the storage device 5 that matches the shooting data shot by the shooting unit 110. Thereafter, the control unit 85 determines whether the specified storage device 5 includes a file that matches the search keyword.

  Hereinafter, a specific description will be given along the flowchart of FIG. Note that description of overlapping parts is omitted as appropriate.

  Steps M4 to M6 are the same as steps K6 to K8 of the eighth application example.

  In step M7, the control unit 85 reads information of the storage device 5 corresponding to the identified recognition ID from the second storage unit 90 or the cache memory. The control unit 85 searches the search keyword information input in step M3 for the read information regarding the storage device 5.

  When the control unit 85 determines that they match (step M8 OK), the control unit 85 performs step M9. When the control unit 85 determines that they do not match (NO in step M8), the control unit 85 performs step M10.

  The processing of steps M9 to M11 is the same as steps K10 to K12 of the eighth application example.

  According to this modification, there are cases in which a search can be performed at a higher speed than the procedure of the flowchart of FIG. In the procedure of the flowchart of FIG. 31, a search based on the search keyword information is also performed on information of the storage device 5 that is not detected by the wireless communication device 15, for example, the storage device 5 that is not at hand. On the other hand, in the modified example of FIG. 33, the search is performed only for the storage device 5 detected by the wireless communication device 15, so that the search can be performed at a higher speed.

(Third modification of the ninth application example)
34 to 36 are diagrams showing a third modification of the ninth application example. As shown in FIG. 34, the user inputs arbitrary priority order information to the storage device 5.

  As shown in FIG. 35, the wireless communication device 15 displays images ranked in the storage device 5 based on the set priority information.

  Specifically, as shown in FIG. 34, the user inputs the order of available capacity as the priority order information. In FIG. 35, the order is displayed in the order of the available capacity.

  FIG. 36 is a flowchart showing a third modification.

  Except for steps N3, N4, and N9, the processing contents are almost the same as those in the flowchart of FIG. In addition, description of overlapping parts will be omitted as appropriate.

  In step N3, the control unit 85 causes the display unit 95 to display a screen including a check column for allowing the user to select a priority order. The user selects a priority order to be selected. The input unit 100 outputs the input priority information to the control unit 85.

  In Step N4, the control unit 85 reads out the information of the storage device 5 shown in FIG. 32 from the second storage unit 90. The control unit 85 compares the read information of the storage device 5 with the priority information, and determines the order of the storage devices 5 in the order of priority.

  In step N9, the control unit 85 generates composite image data corresponding to the priority information determined in step N4, for example, with numbers added as balloons. Note that the priority number may be a number that is absolutely ordered with respect to the storage device 5 stored in the second storage unit 90. Alternatively, the priority order numbers may be numbers that are ordered relative to the storage device 5 detected by the control unit 85 from the captured data.

  According to this modification, it is possible to easily find the storage device 5 that meets the purpose by photographing from the wireless communication device 15 via the photographing unit 110 without checking the information in the storage device 5 one by one. is there.

  As shown in FIG. 34, the priority order information includes, for example, an order suitable for a digital camera (order for digital camera). As the order for digital cameras, for example, the control unit 85 calculates the priority order based on the speed class and free space of the memory card.

  Specifically, information such as shooting image quality, shooting status, camera model number, and the like is input to the wireless communication device 15 in advance. The control unit 85 calculates the priority order according to the input information, for example, according to the speed class, free space, and temperature characteristics of the memory card (for example, the use temperature may be different between the memory card and the USB memory). .

  It is not always necessary for the user to input the above information manually. For example, information may be input by causing a digital camera to communicate with the wireless communication device 15 wirelessly. Alternatively, a digital camera may be photographed via the photographing unit 110, and the control unit 85 may recognize the model number of the digital camera.

(Fourth modification of the ninth application example)
FIG. 37 is a diagram illustrating a fourth modification example of the ninth application example.

  The user sets an arbitrary character for the storage device 5 in the wireless communication device 15. As shown in FIG. 37, the wireless communication device 15 displays a composite image in which the storage device 5 and an arbitrary character overlap each other on the display unit 95 when the storage device 5 is imaged by the imaging unit 110.

  Except for steps O3 and O8, the processing contents are almost the same as those in the flowchart of FIG. In addition, description of overlapping parts will be omitted as appropriate.

  In step O3, the input unit stores a character image corresponding to the recognition ID of the storage device 5 based on the user input. The thumbnail image is not limited to a character image, and may be a thumbnail image of an image stored in the storage device 5 or may be an image obtained by image conversion such as deforming the thumbnail image.

  In step O8, the character image is displayed as a balloon, for example, as shown in FIG. 37 on the storage device 5 associated with the character image in the shooting data.

  In this modification, the character image is not necessarily a still image but may be a moving image. As another modified example, music corresponding to the storage device 5 may be played instead of highlighting.

  According to this modification, it is possible to highlight using a specific character.

(Fifth modification of the ninth application example)
FIG. 39 is a diagram illustrating a fifth modification example of the ninth application example.

  For example, the user inputs a specific date to the wireless communication device 15. As illustrated in FIG. 39, when the wireless communication device 15 captures the storage device 5 with the photographing unit 110, the wireless communication device 15 displays a thumbnail image corresponding to the specific storage device 5 on the display unit 95. Highlight the image corresponding to a specific date. Also, as shown in FIG. 39, an arbitrary character image may be arranged beside the highlighted image.

  FIG. 40 is a table schematically illustrating an example of a method in which the second storage unit 90 of the present modification stores information in the storage device 5.

  As shown in FIG. 40, in correspondence with the recognition ID of the storage device 5, the title corresponding to the recognition ID, the total capacity and the free space of the storage device 5 are stored. One or more file names are stored for the recognition ID, and flag information is stored corresponding to each file name.

  In the example of FIG. 39, an example is shown in which a date “2014.11.1” is input from the user. The control unit 85 sets only the flag of the corresponding file name to 1 and saves it in the second storage unit 90.

  Specifically, in step L3 in FIG. 31, instead of allowing the user to input search keyword information, this can be realized by setting only a specific date. The character image is as described in the fourth modification.

  According to this modification, by highlighting the thumbnail image corresponding to a specific date, the user can easily access the thumbnail image corresponding to the specific date and the storage device 5 storing the image. Can do.

  For example, it is assumed that an image of the play facility is stored in the storage device 5 on the day when the user goes to the play facility. Furthermore, it is assumed that the character image corresponding to the play facility is stored in the storage device 5 in correspondence with the date when the play facility was visited. Here, the storage device 5 and the character image are provided from the amusement facility, for example.

  After a while, the user can enter the date to easily access the characters of the amusement facility and thumbnail images of the photos at that time, and soak up the euphoria. Furthermore, when the user remembers the enjoyable memories, the play facility can expect the user to return as a repeater.

(Second embodiment)
FIG. 41 is a block diagram illustrating the configuration of the storage device 5 according to the second embodiment and the correlation between the wireless communication device 15, the second storage device 1510, the second wireless communication device 1019, and the base station 1530 which are the periphery thereof. . Note that the operation method and the like of the storage device 5 will be described here in order to describe them in detail later.

  The storage device 5 transmits / receives data and commands to / from the wireless communication device 15 according to, for example, the SD interface, but other interfaces may be used. The storage device 5 transmits and receives data and commands to and from the second wireless communication device 1019 along the NFC interface, for example, but other wireless communication interfaces may be used.

  The storage device 5 includes a first controller 1033, a first wireless antenna 20, a nonvolatile semiconductor memory 25, a first NFC controller 30, a memory controller 35, and a connection terminal 65. The first controller 1033, the memory controller 35, and the first NFC controller 30 are not necessarily provided separately, and any combination may be provided integrally.

  The storage device 5 operates with power supplied from the wireless communication device 15 that is electrically connected thereto. The storage device 5 has a function of writing and reading data.

  Further, at least a part of the storage device 5 can be operated by electric power generated (induced) by electromagnetic induction of the first wireless antenna 20. For example, the storage device 5 performs communication in accordance with a near field communication standard (NFC) at a frequency such as 13.56 MHz, and transmits to the second storage device 1510, the second wireless communication device 1019, and the base station 1530. On the other hand, data can be written and read. That is, the storage device 5 can operate without receiving power from the wireless communication device 15. Note that NFC communication can be performed with lower power than general wireless LAN communication.

  Specifically, the first controller 1033, the memory controller 35, and the nonvolatile semiconductor memory 25 operate when the storage device 5 is supplied with power from the wireless communication device 15. When the storage device 5 is only supplied with power via the first wireless antenna 20, the first controller 1033, the memory controller 35, and the nonvolatile semiconductor memory 25 do not necessarily have to operate.

  On the other hand, the first NFC controller 30 is operable even when the storage device 5 is only supplied with power via the first wireless antenna 20. That is, when the first wireless antenna 20 receives a radio wave with a predetermined frequency corresponding to NFC, the first NFC controller 30 becomes operable. That is, the storage device 5 can perform communication by NFC.

  The first controller 1033 receives a command CMD, an address ADD, and data DAT from the wireless communication device 15, the memory controller 35, and the first NFC controller 30.

  The first controller 1033 outputs a command CMD, an address ADD, data DAT, and the like to the memory controller 35, the first NFC controller 30, and the wireless communication device 15 based on the received command CMD.

  The memory controller 35 controls the nonvolatile semiconductor memory 25. The memory controller 35 writes data to the nonvolatile semiconductor memory 25 based on, for example, the command CMD input from the first controller 1033. The memory controller 35 reads data from the nonvolatile semiconductor memory 25 based on, for example, the command CMD input from the first controller 1033 and outputs the data to the first controller 1033. Further, the memory controller 35 may communicate with the first NFC controller 30 and the wireless communication device 15 without passing through the first controller 1033.

  The nonvolatile semiconductor memory 25 is, for example, a NAND flash memory, but is a NOR flash memory, an MRAM (Magnetoresitive Random Access Memory), a PRAM (Phase change Random Access Memory), a ReRAM (Resistive Random). Other nonvolatile semiconductor memories such as Access Memory (resistance change type memory) and FeRAM (Ferroelectric Random Access Memory: ferroelectric memory) may be used. For example, the nonvolatile semiconductor memory 25 may be changed to another nonvolatile memory or the like.

  The nonvolatile semiconductor memory 25 operates when power is supplied from the wireless communication device 15 to the storage device 5.

  The first radio antenna 20 is, for example, a PCB pattern antenna. The frequency band in which the first wireless antenna can operate is set to a predetermined frequency band corresponding to NFC.

  The first wireless antenna 20 can generate electric power by electromagnetic induction based on radio waves from the second wireless communication device 1019, for example. The first wireless antenna 20 supplies the generated power to the first NFC controller 30.

  The first wireless antenna 20 receives a command CMD, an address ADD, and data DAT from the second storage device 1510, the second wireless communication device 1019, and the base station 1530. The first wireless antenna 20 outputs the received command CMD and the like to the first NFC controller 30.

  The first wireless antenna 20 outputs the command CMD or the like input from the first NFC controller 30 to the second storage device 1510, the second wireless communication device 1019, and the base station 1530.

  The first NFC controller 30 includes a first storage unit 40 and a voltage detector 45. The first NFC controller 30 and the first storage unit 40 may be separated from each other.

  The first controller 1033 receives a command CMD, an address ADD, and data DAT from the wireless communication device 15, the memory controller 35, and the first NFC controller 30.

  The first controller 1033 outputs a command CMD, an address ADD, data DAT, and the like to the memory controller 35, the first NFC controller 30, and the wireless communication device 15 based on the received command CMD.

  The first NFC controller 30 communicates with the second wireless communication device 1019 and the like via the first wireless antenna 20.

  The first NFC controller 30 receives a command CMD, an address ADD, data DAT, and the like from the first controller 1033 and the first wireless antenna 20. The first NFC controller 30 outputs data DAT and the like to the first controller 1033 and the first wireless antenna 20, for example, based on the received command CMD.

  The first NFC controller 30 reads the data DAT from the first storage unit 40 based on the received command CMD, address ADD, and the like, and outputs the data DAT to the first controller 1033 and the first wireless antenna 20.

  Further, the first NFC controller 30 writes the data DAT to the first storage unit 40 based on the received command CMD, address ADD, data DAT, and the like.

  Note that the command CMD, address ADD, data DAT, and the like communicated between the wireless communication device 15, the first controller 1033, the memory controller 35, the first NFC controller 30, the first wireless antenna 20, and the like are not necessarily in the same format. do not have to. If the command CMD, the address ADD, and the data DAT are recognizable by both the communicating parties, it is not necessary to formally match the command CMD, the address ADD, the data DAT, and the like used when communicating in other portions.

  When the first NFC controller 30 receives the related data generation command CMD and the data DAT via the first controller 1033 or the first wireless antenna 20, the first NFC controller 30 may generate the related data DAT ′ and write it in the first storage unit 40. .

  Note that the first NFC controller 30 does not necessarily have a writing function to the second wireless communication apparatus 1019 side. That is, it is not necessary to have a function of writing to an NFC tag or the like outside the storage device 5. When the second wireless communication device 1019 writes data to the first storage unit 40 via the first wireless antenna 20, the second wireless communication device 1019 may directly write to the first storage unit 40. That is, the first NFC controller 30 does not necessarily have to write data to the first storage unit 40.

  The first storage unit 40 is, for example, a nonvolatile memory. The first storage unit 40 stores data according to control by the first NFC controller 30 or the memory controller 35. The data storage in the first storage unit 40 may be temporary. As the first storage unit 40, for example, an EEPROM (Electrically Erasable Programmable Read-Only Memory) is used, but various types of memories can be used in the same manner as the nonvolatile semiconductor memory 25.

  In order to enable operation with the power supplied from the first wireless antenna 20, the nonvolatile memory used for the first storage unit 40 has lower power consumption per unit capacity than the nonvolatile semiconductor memory 25. Is preferable. Specifically, a NOR type memory may be used.

  The data stored in the first storage unit 40 includes, for example, related data of the storage device 5 (data stored in the nonvolatile semiconductor memory 25 (for example, various data such as image data, text data, presentation data, and spreadsheet data). ), Data related to the nonvolatile semiconductor memory 25 and the storage device 5, data related to data stored in the nonvolatile semiconductor memory 25, data related to the nonvolatile semiconductor memory 25 and the storage device 5) And data related to the wireless communication device 15 and information on the command CMD received from the first controller 1033, the second wireless communication device 1019, and the like.

  The voltage detector 45 is electrically connected to the first wireless antenna 20. The voltage detector 45 detects the voltage supplied from the first wireless antenna 20 to the first NFC controller 30. The voltage detector 45 then issues a NFC communication reset command until a predetermined voltage at which the first NFC controller 30 can operate is reached. The first NFC controller 30 does not perform NFC communication while receiving this reset command. This reset command can prevent abnormal start-up / operation of communication by NFC. The voltage detector 45 may output an operable command to the first NFC controller 30 when the voltage reaches a predetermined voltage. The first NFC controller 30 performs NFC communication only when an operable command is received.

  The connection terminal 65 is a standardized connection terminal, for example, and can be connected to the wireless communication device 15.

(Operation method of storage device)
Hereinafter, an operation example of the storage device 5 according to the present embodiment will be described with reference to FIGS. 43 to 63. For convenience of explanation, a device that communicates with the storage device 5 via the connection terminal 65 is a first host 1800, and a device that communicates via the first wireless antenna 20 is a second host 1850. Any one of the second storage device 1510, the second wireless communication device 1019, and the base station 1530 in FIG. In addition, as for matters common to the respective operation examples, the description of the contents described in the previous operation examples is omitted without particular notice in the later operation examples.

(First operation example)
FIG. 43 is a diagram schematically showing a data flow in the first operation example. FIG. 44 is a diagram illustrating a first operation example as a flowchart.

  In the first operation example, data stored in the nonvolatile semiconductor memory 25 from the first host 1800 is stored in the first storage unit 40, and the second host 1850 reads data from the first storage unit 40.

  In step S8101, the first controller 1033 receives a write command CMD, an address ADD, and data DAT from the first host 1800 via the connection terminal 65.

  In step S8102, the first controller 1033 outputs a write command CMD, an address ADD, and data DAT to the memory controller 35. Note that, as described above, the write commands CMD in steps S8101 and S8102 do not have to formally match. The same applies to the address ADD and data DAT. The same applies to the following description unless otherwise specified.

  In step S8103, the memory controller 35 writes in the nonvolatile semiconductor memory 25 based on the received command CMD or the like.

  In step S8104, the first controller 1033 outputs a read command CMD and an address ADD to the memory controller 35.

  In step S8105, the memory controller 35 reads the data DAT from the nonvolatile semiconductor memory 25 based on the read command CMD and outputs it to the first controller.

  In step S 8106, the first controller 1033 outputs the received data DAT, write command CMD, and address ADD to the first NFC controller 30.

  In step S8107, the first NFC controller 30 writes the data DAT to the first storage unit 40 based on the received write command CMD or the like.

  In step S8108, the first NFC controller 30 receives a read command CMD and an address ADD from the second host 1850 via the first wireless antenna 20.

  In step S8109, the first NFC controller 30 reads the data DAT from the first storage unit 40 based on the received read command CMD or the like. The first NFC controller 30 outputs data DAT to the second host 1850 via the first wireless antenna 20.

  Note that the above-described procedure is not necessarily performed continuously, and the steps may be separated in time.

(Modification of the first operation example)
Hereinafter, a modification of the first operation example will be described.
The storage device 5 can operate only by supplying power from the second host 1850 via the first wireless antenna 20 in steps S8107 to S8109 of the above operation example.

  After step S8103, after input of a command or the like from the second host 1850, step S8104 and subsequent steps may be processed. In this case, only the data required by the second host 1850 can be moved from the nonvolatile semiconductor memory 25 to the first storage unit 40. In this case, step S8108 may be omitted.

(About data stored in the first storage unit)
In this operation example, the data DAT written in step S8106 and step S8107 (referred to here as DAT2 for convenience) does not necessarily need to match the data DAT written here in step S8103 (referred to as DAT1 here for convenience). That is, the data stored in the nonvolatile semiconductor memory 25 and the data stored in the first storage unit 40 do not need to match. This is the same in the following operation examples.

  For example, DAT2 may be a part of DAT1. DAT2 may be data obtained by processing DAT1 data. For example, when DAT1 is image data, DAT2 may be image data obtained by compressing DAT1, and when DAT2 is sound data, DAT2 may be a more compressed sound or the sound at the beginning. It may be data.

  Thus, the data stored in the nonvolatile semiconductor memory 25 and the data stored in the first storage unit 40 do not necessarily match. As a method for extracting data stored in the first storage unit 40, three methods will be described as specific examples.

  First, as a first method, the first host 1800 outputs a special command CMD, an address ADD, data DAT, and the like to the first controller 1033. In this method, which data is transferred to the first storage unit 40 is specified by the address ADD and the data DAT.

  The first controller 1033 reads the specified data from the nonvolatile semiconductor memory 25 using the memory controller 35. Furthermore, the first controller 1033 outputs the read data to the first NFC controller 30 and writes the data to the first storage unit 40 using the first NFC controller. This method can transfer data as the user intends.

  Next, as a second method, a setting file is stored in the nonvolatile semiconductor memory 25 in advance. In the case of this method, the first controller 1033 uses the memory controller 35 when the nonvolatile semiconductor memory 25 can be driven (for example, when the storage device 5 is supplied with power from the first host 1800). Read the configuration file. Then, the first controller 1033 transmits data to the first storage unit 40 based on the read setting file.

The setting file includes, for example, a file name (eg, initials start with a specific character), extension (eg, specific extension), date order (eg, 10 from the newest), flag information only, etc. One or more of these various conditions are set. Then, the first controller 1033 writes data that satisfies the condition into the first storage unit 40 using the first NFC controller 30. It should be noted that the first controller 1033 may write only the changed portion in the first storage unit 40, or may rewrite the whole every time.
Note that the method of reading data from the nonvolatile semiconductor memory 25 and storing the data in the first storage unit 40 is the same as the first method, and thus the description thereof is omitted.

  Furthermore, as a third method, the setting file may be stored in the first storage unit 40. In this case, the setting file can be written even when power is supplied only from the second host 1850.

When receiving power supply from the first host 1800, the first controller 1033 reads the setting file from the first storage unit 40. At this time, the first controller 1033 may store the setting file in the nonvolatile semiconductor memory 25.
Since the subsequent flow is the same as in the second method, the description is omitted.

  As described above, various methods can be used as a method for extracting data stored in the first storage unit 40. Of course, the above three methods are not intended to limit the extraction method to these methods.

The first controller 1033 interprets the command CMD via the memory controller 35 and writes the data DATA to the nonvolatile semiconductor memory 25 (2-1). Thereafter, the first controller 1033 outputs the written data DATA through the memory controller 35 (2-2). The first controller 1033 writes the data DATA to the first storage unit 40 via the first NFC controller 30 (3-1). The second host 1850 transmits a read command CMD to the first NFC controller 30 (4-2), and the first NFC controller 30 reads data DATA from the first storage unit 40.

  As shown in FIG. 57, in the second operation example, after the second host 1850 outputs the write command CMD to the first storage unit 40 (4-1), data DATA is transmitted to the first controller 1033 ( 3-2). The first NFC controller 30 writes data DATA in the first storage unit 40. The first NFC controller 30 outputs the written data DATA to the first controller 1033. The first controller 1033 writes the data DATA to the nonvolatile semiconductor memory 25 via the memory controller 35 (2-1). Subsequently, the first host 1800 transmits a read command CMD to the first controller 1033 (1-2), and the first controller 1033 that has received the read command CMD transfers the data DATA to the nonvolatile semiconductor via the memory controller 35. Read from the memory 25 (2-2). The first controller 1033 transmits the read data DATA to the first host 1800.

  As shown in FIG. 58, in the third operation example, after the first host 1800 outputs the write command CMD to the first storage unit 40 (5-1), the data DATA is transmitted to the first controller 1033. The first controller 1033 that has received the data DATA writes the data DATA to the first storage unit 40 via the first NFC controller 30 (3-1). The second host 1850 transmits a read command CMD to the first NFC controller 30, and reads data DATA from the first storage unit 40 by the first NFC controller 30 (4-2).

  As shown in FIG. 59, in the fourth operation example, after the second host 1850 outputs the write command CMD (4-1), the data DATA is transmitted to the first controller 1033. Data DATA is written to the first storage unit 40 by the first NFC controller 30. The first host 1800 transmits a read command CMD to the first storage unit 40 (5-2), and the first controller 1033 reads the data DATA from the first storage unit 40 via the first NFC controller 30 ( 3-2). The read data DATA is transmitted to the first host 1800 by the first controller 1033.

  As shown in FIG. 60, in the fifth operation example, the first host 1800 outputs a write command CMD to the first controller 1033 (1-1). The command at this time is a through write command for passing through the writing to the first storage unit 40. The first controller 1033 that has received the data DATA writes the data DATA to the nonvolatile semiconductor memory 25 via the memory controller 35 (2-1). The second host 1850 transmits a read command CMD to the nonvolatile semiconductor memory 25 (6-2). The read command at this time is a through read command that passes through the reading from the first storage unit 40. The first controller 1033 reads data DATA from the nonvolatile semiconductor memory 25 by a through read command (2-2).

  As shown in FIG. 61, in the sixth operation example, the second host 1850 transmits a write command to the nonvolatile semiconductor memory 25 and transmits data DATA (6-1). The first controller 1033 writes the transmitted data DATA to the nonvolatile semiconductor memory 25 via the memory controller 35 (2-1). When the first host 1800 transmits a read command to the first controller 1033 (1-2), the first controller 1033 reads data DATA from the nonvolatile semiconductor memory 25 via the memory controller 35 (2-2). .

  As shown in FIG. 62, in the seventh operation example, the second host 1850 transmits a write command or a read command (7-1 or 7-2), and then transmits data DATA. The first controller 1033 transmits the transmitted data DATA to the first host 1800 based on either the write command or the read command (8-1 or 8-2). Note that the command of the first controller 1033 at this time may be either a write command or a read command, or may be a command arbitrarily set by the user.

  FIG. 63 is a table summarizing the above-described operation example of the storage device 5 and its advantages. Each arrow indicates the flow of data, and the hatched area indicates a state in which operation is possible in a state where power is supplied from the first host 1800 side. Note that the non-volatile semiconductor memory 25 and the first storage unit 40 can hold data only when data is not held from the first host side.

  As shown in the first row of FIG. 63, in the first operation example, data transfer from the first host 1800 to the second host 1850 is performed by writing to the nonvolatile semiconductor memory 25 and the first storage unit 40 and This is done via reading. In the first operation example, data transmission from the first storage unit 40 to the second host 1850 is performed by NFC communication. Therefore, even if no power is supplied from the first host 1800, the second host 1850 Data can be acquired from the first storage unit 40.
