More specifically, at least one content file 60 is associated with the album 51, and preferably the content file 60 is associated with at least one album 51 of the plurality of albums 51. Accordingly, one content file 60 may be associated with a plurality of albums 51, or there may be a content file 60 that is not associated with any album 51. In the example shown in FIG. 6, there are a plurality of albums 51 named “XX child”, “New Year”, “travel”, and the like, and a plurality of content files 60 are associated with each album 51. In the present embodiment, as a method of associating the content file 60 and the album 51 in the storage unit 71, a method of inputting specific tag data to the tag table 62 is exemplified. However, the content file 60 and the album 51 are associated. The method is arbitrary, and as an example, a folder corresponding to the album 51 may be created in the storage unit 71 and the content file 60 may be stored in this folder.

  Alternatively, when the tag data in the tag table 62 includes a tag indicating imaging time data when the content file 60 associated with the tag data is captured, the display control unit 75 stores the content file 60. A display screen generation signal to be displayed on the display screen 4a of the display device 4 may be generated in the order of the imaging time data (any of early order and late order).

  The display control unit 75 then displays a display screen generation signal for displaying the content data 60 a to be displayed on the display screen 4 a of the display device 4 based on the display target list 63 generated by the display target list creation unit 77. Is generated.

  Further, the display target list creating unit 77 receives an input signal for an instruction to change the content file 60 (content data 60a) to be displayed from one input device while the display screen 4 is displayed on the display device 4. If accepted, the display target list 63 is updated.

  As an example, when the content file 60 is displayed on each of the display screens 2 a and 4 a of the browsing device 2 and the display device 4, the user operates the input instruction device 5 to change the content file 60 to be displayed. When the input instruction device 5 outputs an input signal for instructing the input and the input unit 72 receives the input signal, the display target list creating unit 77 displays the display screen 4 a of at least the display device 4 among the browsing device 2 and the display device 4. The display screen generation signal for display on the screen is updated. Therefore, the display control unit 75 generates a display screen generation signal for displaying the content file 60 to be displayed on the display screen 4 a of the display device 4 based on the updated display target list 63.

  There may be various input signals from the input device for which the display target list creating unit 77 determines to update the display target list 63. As an example, when the display target list 63 created by the display target list creating unit 77 is a list of content files 60 classified into a specific group, in other words, associated with a specific album 51, the display target list The input signal from the input device for which the list creating unit 77 determines to update the display target list 63 is an input signal for newly specifying the content file 60 associated with the specific album 51 as a display target, or the album 51. Separation other than the unit, for example, an input signal that designates a content file 60 having tag data not associated with the album 51 as a display target, and further specifies all content files 60 stored in the storage unit 71 as a display target. Input signal. Alternatively, it is an input signal for instructing the user to operate the input device to delete the content file 60 currently displayed on the display screen 4 a of the display device 4 from the storage unit 71.

  Here, as in the present embodiment, the browsing device 2 has a function as a display device, so that the display device (the browsing device 2 and the display device 4) as the entire image management system S is the input device (the browsing device 2, the input device). At least as many as the instruction devices 5), each input device is associated with one of the display devices, and the input signal from the input device displays the content data 60a on the display screen of the associated display device In the case of including an input signal to be displayed, the display target list creating unit 77 preferably creates the display target list 63 corresponding to each display device, that is, the browsing device 2 and the display device 4. Then, the display control unit 75 displays the content file 60 to be displayed as the browsing device 2 based on the display target list 63 created by the display target list creating unit 77 corresponding to the browsing device 2 and the display device 4. Display screen generation signals to be displayed on the display screens 2a and 4a with the device 4 may be generated.

  Furthermore, the display control unit 75 is configured to display each display device, that is, the browsing device 2 and the display device 4 based on the display target list 63 created by the display target list creation unit 77 corresponding to the browsing device 2 and the display device 4. A display screen generation signal for displaying the content file 60 that can be displayed simultaneously on each of the display screens 2a and 4a may be generated. Furthermore, it is preferable that the display control unit 75 generates a display screen generation signal for simultaneously displaying the plurality of content files 60 on the respective display screens 2 a and 4 a of the browsing device 2 and the display device 4. As such display screens 2a and 4a displayed on the browsing device 2 and the display device 4 by the display screen generation signal generated by the display control unit 75, a display screen called a so-called thumbnail display is preferably exemplified. In the thumbnail display, a single or a plurality of content files 60 belonging to a specific album 51 are simultaneously displayed in a predetermined size on the display screens 2a and 4a.

  Alternatively, the display control unit 75 may generate a display screen generation signal for displaying the display screens 2a and 4a called so-called slide show display. The mode of the slide show display by the display control unit 75 is arbitrary, and an example is a mode in which the content file 60 is displayed at predetermined time intervals while being sequentially switched. Naturally, an example in which the display control unit 75 displays the content file 60 is not limited to the above-described slide show display, and a display similar to an album for pasting a silver halide photograph called a so-called photo book may be displayed. .

  Here, when the image management system S includes a plurality of display devices (the browsing device 2 and the display device 4) as in the present embodiment, the display control unit 75 receives a display screen generation signal from the display control unit 75. The display screen generation signal for displaying the content file 60 that can be displayed on one display screen is displayed on some display devices among the display devices other than the display device to which the message is sent. It may be generated based on the list 63 and transmitted. In the case of the present embodiment, the display control unit 75 preferably displays a display screen generation signal for displaying the content file 60 that can be displayed on one display screen 4a on the display device 4 among the plurality of display devices. Is generated and transmitted based on the display target list 63 created by the display target list creating unit 77 corresponding to the display device 4.

  When the image management system S includes a plurality of display devices (browsing device 2 and display device 4) as in the present embodiment, the content data transmission unit 78 is created by the display target list creation unit 77. Based on the display target list 63, the content file 60 is sent to some of the plurality of display devices. In the case of the present embodiment, preferably, the content data transmission unit 78 provides the content file 60 to the browsing device 2 based on the display target list 63 created by the display target list creation unit 77 corresponding to the browsing device 2. Is sent out.

  The display control unit 75 displays the content file 60 that can be displayed simultaneously on one display screen on each display device other than the display device to which the content file 60 is sent from the content data transmission unit 78. A display screen generation signal may be generated and transmitted based on the display target list 63. In the case of the present embodiment, the display control unit 75 preferably displays one display on a display device other than the browsing device 2 that is a display device to which the content file 60 is transmitted from the content data transmission unit 78, that is, on the display device 4. A display screen generation signal for displaying the content file 60 that can be displayed simultaneously on the screen 4 a is generated and transmitted based on the display target list 63 created by the display target list creation unit 77 corresponding to the display device 4. .

  The difference between the display control unit 75 and the content data transmission unit 78 will be supplemented. The display control unit 75 outputs a display screen generation signal for displaying the content file 60 stored in the storage unit 71 on the display screens 2 a and 4 a of the browsing device 2 and the display device 4. On the other hand, the content data transmission unit 78 is based on the display target list 63 created by the display target list creation unit 77, and is a part of a plurality of display devices, that is, the browsing device 2 and the display device 4, preferably browsing. The content file 60 is sent to the device 2. That is, the display control unit 75 outputs a display screen generation signal for the display device 2 and the display device 4 to display the content file 60 on the display screens 2a and 4a, while the content data transmission unit 78 2 sends out the content file 60 itself.

  The related information update unit 76 updates the related information stored in the storage unit 71 based on the input signal received by the input unit 72. As an example, in a state where the content file 60 is displayed on each of the display screens 2a and 4a of the browsing device 2 and the display device 4, the user operates the browsing device 2 to instruct updating of tag data in the tag table 62. The browsing device 2 outputs the input signal to be received, the input unit 72 of the image management device 1 receives the input signal, and the related information update unit 76 is instructed to update the tag in the tag table 62 based on the input signal. Update the data.

  Then, even when the related information update unit 76 updates the related information based on the input signal received by the input unit 72, the display target list creation unit 77 issues an instruction to change the content file to be displayed from one input device. The display target list 63 is updated only when an input signal is received. In other words, even when the related information update unit 76 updates the related information based on the input signal received by the input unit 72, the display target list creation unit 77 instructs the change of the content file to be displayed from one input device. The display target list 63 is not updated until the input signal is received.

  As an example, the related information update unit 76 is stored in the storage unit 71 based on the input signal from the browsing device 2 in a state where the display control unit 75 displays the content file 60 on the display screen 4 a of the display device 4. Even when the tag data being updated is updated, the display target list creating unit 77 of the content file 60 to be displayed is displayed only when an input signal for changing the content file 60 to be displayed is received from the input instruction device 5. The display target list 63 is updated when an input signal for a change instruction is received. In other words, even when the related information update unit 76 updates the tag data stored in the storage unit 71, the display target list creation unit 77 inputs an instruction to change the content file 60 to be displayed from the input instruction device 5. The display target list 63 is not updated until the signal is received. Thereby, the display target list creation unit 77 can appropriately update the display target list 63 only when the display target list 63 should be updated.

  Furthermore, even when the related information update unit 76 updates the related information while the display screen is displayed on the display device, the display control unit 75 only updates the display target list 63 by the display target list creation unit 77. Update the display screen generation signal. In other words, the display control unit 75 continues until the display target list creation unit 77 updates the display target list 63 even when the related information update unit 76 updates the related information while the display screen is displayed on the display device. Do not update the display screen generation signal.

  As an example, even when the related information update unit 76 updates the related information while the display screen 4 a is displayed on the display device 4, the display control unit 75 updates the display target list 63 with the display target list creation unit 77. The display screen generation signal is updated only when In other words, in the display control unit 75, even when the related information update unit 76 updates the related information while the display screen 4a is displayed on the display device 4, the display target list creation unit 77 updates the display target list 63. Do not update the display screen generation signal until

  The input unit 72 receives various input signals input to the image management device 1 from external input devices including the browsing device 2, the imaging device 3, and the input instruction device 5, and inputs the received input signals to the control unit 70. Accordingly, the data is stored in the storage unit 71 via the control unit 70. The output unit 73 outputs various data in the control unit 70 or the storage unit 71 including a display screen generation signal to an external output device including the browsing device 2 and the display device 4.

  Further, the browsing device 2 constituting the image management system S of the present embodiment includes a display unit 79 and an operation unit 80. The display unit 79 receives a display screen generation signal input to the browsing device 2 from an external device including the image management device 1, and displays the display screen 2a based on the received display screen generation signal. The operation unit 80 generates an input signal in response to an operation by the user, and outputs the input signal to an external device including the image management apparatus 1.

  In the above configuration, the image capturing unit 74, the display control unit 75, the related information update unit 76, the display target list creation unit 77, and the content data transmission unit 78 constituting the control unit 70 and the control unit 70 are mainly configured by the CPU 20. The storage unit 71 is mainly composed of the memory card 7, ROM 21, RAM 22, and HDD unit 26, the input unit 72 is mainly composed of the input / output device 23, the network interface 25, and the wireless LAN interface 27, and the output unit 73 is main. The HDMI interface 24, the network interface 25, and the wireless LAN interface 27 are included. The display unit 79 is mainly configured by the display device 43, and the operation unit 80 is mainly configured by the input / output device 47. The operation of each functional unit shown in FIG. 4 will be described in detail later.

(Operation of Image Management System of First Embodiment)
Next, the operation of the image management system S of the present embodiment will be described with reference to the flowcharts of FIGS. FIGS. 9 and 10 are flowcharts for explaining an operation of browsing the content file 60 stored in the image management apparatus 1 constituting the image management system S of the present embodiment by the browsing apparatus 2.

  The flowchart shown in FIG. 9 is started by an operation such as launching an application for browsing the content file 60 in the browsing device 2. First, in step S1, the display control unit 75 of the image management device 1 generates a display screen generation signal for displaying an initial screen on the display screen 2a of the browsing device 2, and outputs the display screen generation signal to the output unit. It transmits to the browsing apparatus 2 via 73. In step S2, the display unit 79 of the browsing device 2 receives the display screen generation signal, and displays an initial screen on the display screen 2a based on the display screen generation signal.

  In step S3, the operation unit 80 of the browsing device 2 waits for the user to input browsing conditions. When the browsing conditions are input by the user (YES in step S3), the input is performed by the user in step S4. The operation unit 80 transmits a browsing request for the content file 60 together with the browsing conditions to the image management apparatus 1. Here, the browsing condition is a condition of the content file 60 to be displayed on the display screen 2a of the browsing device 2, and is a condition for designating a specific album 51 as an example.

  On the other hand, in step S5, the display target list creation unit 77 of the image management apparatus 1 waits for the input unit 72 to receive a browsing request from the browsing device 2, and when the input unit 72 receives the browsing request together with the browsing conditions ( In step S5, YES), in step S6, the display target list creation unit 77 searches the content file 60 and the tag table 62 stored in the storage unit 71 based on the viewing conditions, and selects the content file 60 that matches the viewing conditions. Extract.

  In step S7, the display target list creation unit 77 creates the browsing list 104 of the content file 60 that matches the browsing conditions based on the extraction result in step S6.

  In step S8, the display target list creation unit 77 of the image management apparatus 1 transmits the browsing list 104 via the output unit 73. In step S9, the display unit 79 of the browsing apparatus 2 is transmitted from the image management apparatus 1. The browsing list 104 is received, and a transmission request for the thumbnail file 61 associated with the content file 60 displayed on the display screen 2a is transmitted to the image management apparatus 1 based on the manner in which the content file 60 is displayed on the display unit 79. . In step S <b> 10, the content data transmission unit 78 transmits the thumbnail file 61 requested for transmission via the output unit 73 based on the transmission request for the thumbnail file 61 transmitted from the browsing device 2. In step S11, the display unit 79 displays the thumbnail file 61 transmitted from the image management apparatus 1 on the display screen 2a.

  The specific content of the mode of displaying the content file 60 on the display unit 79 can be various modes such as the thumbnail display and the slide show display as already described, and thus detailed description thereof is omitted here. The display mode of the content file 60 on the display unit 79 can be set as appropriate by the user. The display unit 79 determines which (sometimes a plurality of) thumbnail files 61 of the content file 60 are necessary in the set display mode with reference to the browse list, and uses the information described in the browse list. Then, a transmission request for the content file 60 that needs to be displayed is transmitted.

  Next, the operations from step S12 to step S20 are the same as the operations from step S3 to step S11 described above, and detailed description thereof is omitted. However, in step S12, when a new browsing condition is not input by the user (NO in step S12), the program proceeds to step S21. Similarly, in step S14, the input unit 72 does not receive a browsing request together with the browsing condition. If (NO in step S14), the program is different only in that it moves to step S23.

  Next, in step S21, when the user operates the operation unit 80 of the browsing device 2, the content file 60 (thumbnail file 61) currently displayed on the display screen 2a is displayed for any one of the content files 60. It is determined whether or not an enlarged display request has been input, and if the enlarged display request has been input by the user (YES in step S21), the program proceeds to step S22, and no enlarged display request has been input at that time. If (NO in step S21), the program proceeds to step S26. In step S22, the display unit 79 has better image quality than the content file 60 to which an enlarged display request is input or the thumbnail file 61 currently displayed on the display screen 2a of the browsing device 2, in other words, has a higher resolution, or A transmission request for the thumbnail file 61 having a low compression rate is transmitted to the image management apparatus 1. For example, the display control unit 75 of the image management apparatus 1 determines whether to transmit the content file 60 or the thumbnail file 61 with good image quality.

  On the other hand, in step S23, it is determined whether or not the input unit 72 of the image management apparatus 1 has received a transmission request for the content file 60 or the like transmitted from the browsing apparatus 2, and the transmission request for the content file 60 or the like has been received. If (YES in step S23), the program proceeds to step S24. If a transmission request for content file 60 has not been received at this time (NO in step S23), the program proceeds to step S28.

  In step S24, the content data transmission unit 78 of the image management apparatus 1 extracts the content file 60 and the like requested for transmission from the storage unit 71, and transmits the content file 60 and the like to the browsing device 2 via the output unit 73. To do. In step S25, the display unit 79 of the browsing device 2 receives the content file 60 and the like transmitted from the image management device 1, and displays the received content file 60 and the like on the display screen 2a in an enlarged manner.

  Next, in step S26, when the user operates the operation unit 80 of the browsing device 2, the content file 60 (thumbnail file 61) currently displayed on the display screen 2a is associated with one of the content files 60. It is determined whether or not an edit request for the tag data in the tag table 62 is input. If the edit request is input by the user (YES in step S26), the program proceeds to step S27 and the edit request is received. If it is not input at that time (NO in step S26), the program returns to step S12, and thereafter, the operations in steps S12 to S27 are repeated. In step S <b> 27, the operation unit 80 transmits the edited / updated tag data input by the user by operating the operation unit 80 to the image management apparatus 1.

  On the other hand, in step S28, it is determined whether the input unit 72 of the image management apparatus 1 has received the edited tag data transmitted from the browsing apparatus 2, and received the edited tag data (in step S28). If YES, the program proceeds to step S29, and if the edited tag data has not been received at that time (NO in step S28), the program returns to step S14, and thereafter, from step S14 to step S29. Repeat the operation. In step S29, the related information update unit 76 updates the tag table 62 in the storage unit 71 using the edited tag data transmitted from the browsing device 2.

  Next, FIGS. 11 to 13 are flowcharts for explaining an operation of browsing the content file 60 stored in the image management apparatus 1 constituting the image management system S of the present embodiment by the browsing apparatus 2.

  The flowchart shown in FIG. 11 is started by an operation such as starting the image management apparatus 1. First, in step S30, the display control unit 75 of the image management device 1 generates a display screen generation signal for displaying an initial screen on the display screen 4a of the display device 4, and outputs the display screen generation signal to the output unit. The data is transmitted to the display device 4 via 73. The display device 4 receives the display screen generation signal and displays an initial screen on the display screen 4a based on the display screen generation signal.

  In step S31, the operation unit 5a of the input instruction device 5 is operated by the user to wait for the viewing condition to be input. When the viewing condition is input by the user (YES in step S31), in step S32 The input instruction device 5 transmits a request for browsing the content file 60 to the image management device 1 together with the browsing conditions input by the user.

  On the other hand, in step S33, the display target list creation unit 77 of the image management apparatus 1 waits for the input unit 72 to receive the browsing request from the input instruction device 5, and when the input unit 72 receives the browsing request together with the browsing conditions. (YES in step S33), in step S34, the display control unit 75 searches the content file 60 and the tag table 62 stored in the storage unit 71 based on the viewing conditions, and extracts the content file 60 that matches the viewing conditions. To do.

  In step S35, the display target list creation unit 77 creates the intermediate list 105 of the content files 60 that match the viewing conditions based on the extraction result in step S6. In step S36, the intermediate list created in step S35. Based on the display mode in which the content file 60 is displayed on the list 105 and the display screen 4 a of the display device 4 at this time, the display target list creating unit 77 creates the display list 106.

  In step S37, the display control unit 75 displays a display screen generation signal for displaying the thumbnail file 61 corresponding to the content file 60 described in the display list 106 created in step S36 on the display screen 4a of the display device 4. Is transmitted to the display device 4 via the output unit 73. The display device 4 displays the thumbnail file 61 on the display screen 4a based on the display screen generation signal transmitted from the image management device 1. As for the specific contents of the mode of displaying the content file 60 on the display device 4, various modes such as the thumbnail display and the slide show display as described above are possible, and thus detailed description thereof is omitted here. The display mode of the content file 60 on the display device 4 can be appropriately set by the user.

  In step S38, it is determined whether or not the user has operated the operation unit 5a of the input instruction device 5. If the user has operated the operation unit 5a of the input instruction device 5 (YES in step S38), the program is executed in step S39. The input instruction device 5 transmits operation information based on the user's operation to the image management device 1. On the other hand, if the user has not operated the operation unit 5a of the input instruction device 5 at that time (NO in step S38), the program proceeds to step S43.

  In step S40, it is determined whether or not the input unit 72 of the image management apparatus 1 has received the operation information from the input instruction device 5. If the input unit 72 has received the operation information (YES in step S40), the program is The process proceeds to step S41. On the other hand, if input unit 72 has not received the operation information at that time (NO in step S40), the program proceeds to step S45.

  In the operation input of the input instruction device 5 in step S38 and the operation information reception in step S39, the operation input input by the user using the operation unit 5a and the operation information based on the input are the re-input of the viewing conditions described later, the content This is an operation input excluding the enlarged display of the file 60 and the tag data editing input. Preferably, the operation input and the operation information are an operation input for displaying a content file 60 different from the content file 60 currently displayed on the display screen 4a among the content files 60 based on the viewing conditions.

  In step S41, the display target list creation unit 77 updates the display list 106 based on the intermediate list 105 created in step S35, the operation input received by the input unit 72 in step S40, and the operation information based thereon. In step S42, the display control unit 75 displays a display screen generation signal for displaying on the display screen 4a of the display device 4 the thumbnail file 61 corresponding to the content file 60 described in the display list 106 updated in step S41. Is transmitted to the display device 4 via the output unit 73.

  Since the operation from step S43 to step S57 is the same as the operation from step S12 in FIG. 8 to step S29 in FIG. 9, the description thereof is omitted here. However, a display screen generation signal for displaying the thumbnail file 61 and the content file 60 is transmitted from the display control unit 75 of the image management device 1 to the display device 4.

  Further, every time the input unit 72 receives browsing conditions from the input instruction device 5, the display target list creation unit 77 discards the intermediate list 105 and the display list 106 that have been stored in the storage unit 71 so far and is input. An intermediate list 105 and a display list 106 are newly created based on the browse conditions. In other words, the display target list creation unit 77 does not update the intermediate list 105 and the display list 106 until a new browsing condition is received from the input instruction device 5. Accordingly, if the content file 60 related to the specific album 51 is displayed on the display screen 4 a of the display device 4, the content file 60 belonging to the specific album 51 is based on the input from the browsing device 2. Even if the number is increased or decreased, until the display target list creation unit 77 newly creates the intermediate list 105 and the display list 106 based on the viewing conditions received from the input instruction device 5, the album 51 based on the input from the viewing device 2 is displayed. The update result is not reflected on the display screen 4 a of the display device 4.

  In step S58, using the edited tag data transmitted from the input instruction device 5, the display control unit 75 displays the thumbnail file 61 corresponding to the content file 60 described in the display list 106 on the display screen of the display device 4. A display screen generation signal for display on 4 a is transmitted to the display device 4 via the output unit 73. The display device 4 displays the thumbnail file 61 on the display screen 4a based on the display screen generation signal transmitted from the image management device 1.
