In the present embodiment, as shown in FIG. 5, the first content file 60 is stored in the storage unit 45 (the HDD 261 constituting the storage unit 45) in association with the album 33, which is a plurality of groups. More specifically, at least one first content file 60 is associated with the album 33, and preferably, the first content file 60 is associated with at least one album 33 of the plurality of albums 33. Therefore, one first content file 60 may be associated with a plurality of albums 33, or there may be a first content file 60 that is not associated with any album 33. In the example shown in FIG. 5, there are a plurality of albums 33 named “XX child”, “New Year”, “travel”, etc., and a plurality of first content files 60 are associated with each album 33. ing. In the present embodiment, as a method of associating the first content file 60 and the album 33 in the storage unit 45, a method of inputting specific tag data to the tag table 63 is illustrated, but the first content file 60 The method of associating the album 33 with the album 33 is arbitrary, and as an example, a folder corresponding to the album 33 may be created in the storage unit 45 and the content file 60 may be stored in this folder.

  The first management information file 62 stores data relating to management information including predetermined display conditions when a display screen for displaying the first content file 60 is generated by the display control unit 49 described later. Although details will be described later, as an example, when the display control unit 49 performs a slide show display, information for specifying the first content file 60 that is the target of the slide show display, the information of the first content file 60 that is the target. A display time including a display interval, a display mode, and the like are examples of data relating to the above display conditions. Here, as information for specifying the first content file 60 to be subjected to the slide show display, the file name of the first content file 60, the first tag data 60b or the first tag data 63 in the tag table 63 is used. Data that can uniquely specify the content file 60 and information for specifying the album 33 described above are included.

  The second management information file 66 also stores data related to management information including predetermined display conditions when a display screen for displaying the second content file 64 is generated by the display control unit 49 described later. However, in the present embodiment, the data relating to the display conditions included in the second management information file 66 does not include information for specifying the album 33 described above.

  The control unit 40 includes a capture unit 47, an input unit 48, and a display control unit 49. The capturing unit 47 includes a medium detection unit 50 and a management information detection unit 51.

  The capturing unit 47 captures a content file 60 including content data 60 a generated by an external device such as the imaging device 3 and stores the content file 60 in the storage unit 41. More specifically, the medium detection unit 50 of the capturing unit 47 detects that the imaging device 3 or the memory card 7 is connected to the input I / F unit 42 of the information processing device 1. Next, the management information detection unit 51 of the capture unit 47 determines whether or not the second management information file 66 is stored in the imaging device 3 or the memory card 7 connected to the input I / F unit 42. If the management information detection unit 51 determines that the second management information file 66 is stored in the memory card 7 or the like, the capture unit 47 is connected to the imaging device 3 or the memory connected to the input I / F unit 42. If the content file 60 stored in the card 7 is taken into the temporary storage unit 46 as the second content file 64 and it is determined that the second management information file 66 is not stored, the take-in unit 47 takes the image pickup device 3. Alternatively, the content file 60 stored in the memory card 7 is taken into the storage unit 45 as the first content file 60.

  In addition, when the management information detection unit 51 determines that the second management information file 66 is stored in the memory card 7 or the like, the capture unit 47 determines that the second management information stored in the memory card 7 or the like is stored. The file 66 is also preferably stored in the temporary storage unit 46.

  Although the method of storing the content file 60 in the storage unit 45 or the temporary storage unit 46 as the first content file 60 or the second content file 64 is arbitrary, as an example, the imaging device 3 captures images as described above. When the obtained content file 60 is stored in the memory card 7, the memory card 7 is inserted into the card slot of the card interface 232, and the memory card 7 is connected to the input I / F unit 42, the medium detection unit 50. The content file 60 stored in the memory card 7 as a result of being recognized and detected is taken into the storage unit 45 or the like as the first content file 60 or the second content file 64.

  Further, the USB cable 6 connected to the imaging device 3 that captured the content file 60 is inserted into the USB connector of the USB interface 233, and the medium detection unit 50 recognizes the imaging device 3 as a USB device in conformity with the USB standard. The content file 60 stored in the imaging device 3 by (negotiation) may be taken into the storage unit 45 or the like as the first content file 60 or the second content file 64.

  Here, the capture unit 47 determines whether or not the first content file 60 to be captured is already stored in the storage unit 45. If it is determined that the first content file 60 is not stored in the storage unit 45, the first content file 60 is determined. The content file 60 may be stored in the storage unit 45.

  The determination by the capturing unit 47 whether or not the first content file 60 to be captured has already been stored in the storage unit 45, in other words, the determination of duplicate storage in the storage unit 45 is appropriately performed by a known method. It can be implemented.

  As an example, there is a duplicate storage determination using a hash value. First, when the capturing unit 47 stores the first content file 60 in the storage unit 45, or after storing the first content file 60 in the storage unit 45, the first content file 60 of the first content file 60 is stored. A hash value of the content data 60 a is calculated, and this hash value is stored as tag data in the tag table 63. Next, a hash value of the first content data 60a of the first content file 60 to be captured is calculated, and whether or not tag data having a hash value matching the hash value exists in the tag table 63 is determined. judge. In addition to this, the feature value extracted as a result of performing predetermined image processing on the content data 60a to be captured and the first content data 60a stored in the storage unit 45 are similarly determined in advance. Duplicate storage determination may be performed depending on whether or not feature values extracted as a result of image processing match. The feature value calculation method may be appropriately selected from well-known methods, and examples include a SIFT (Scale-invariant Feature Transform) feature value and a SURF (Speeded Up Robust Features) feature value calculation method.

  Further, when the medium detection unit 50 detects that the imaging device 3 or the memory card 7 has been removed from the information processing device 1, in other words, the connection has been released, the capture unit 47 is stored in the temporary storage unit 46. It is preferable to delete the second content file 64. In addition, it is preferable that the capturing unit 47 deletes the second thumbnail file 65 and the second management information file 66 together with the second content file 64.

  The input unit 48 accepts various setting inputs including display conditions of the content file 60 by the display control unit 49 described later.

  The display control unit 49 displays a desired display screen on the display surface 4 a of the display device 4 via the output I / F unit 43 based on requests from the control unit 40 and various functional units constituting the control unit 40. A display screen generation signal is generated.

  As an example, the display control unit 49 generates a display screen generation signal for displaying the content file 60 stored in the storage unit 45 and the temporary storage unit 46 on the display surface 4 a of the display device 4. At this time, the display control unit 49 sets the second content file 64 to the second management information file 66 based on the display conditions stored in the first management information file 62 for the first content file 60. A display screen generation signal is generated based on the stored display conditions.

  At this time, the display control unit 49 may generate a display screen generation signal for displaying a plurality of content files 60 on one display screen. As such a display screen displayed on the display device 4 by the display screen generation signal generated by the display control unit 49, a display screen called a so-called thumbnail display is preferably exemplified. In this thumbnail display, one or a plurality of content files 60 are displayed in a predetermined size on the display screen.

  Alternatively, the display control unit 49 may generate a display screen generation signal for displaying a display screen called a so-called slide show display. The mode of the slide show display by the display control unit 49 is arbitrary, and an example is a mode in which the content file 60 is displayed at predetermined time intervals while being sequentially switched at predetermined time intervals or at predetermined time intervals.

  Further, when the content files 60 are sequentially switched, a display effect at the time of display switching such as moving the content file 60 to be displayed next from one end of the display surface 4a of the display device 4 toward the center may be added. .

  Furthermore, when the number of pixels of the content data 60a is different for each content data 60a, each content file 60 is more or less accurately displayed on the entire display surface 4a in accordance with the number of pixels on the display surface 4a. The content file 60 may be enlarged / reduced so that the area where the content file 60 is not displayed is as small as possible.

  In addition, when the size relationship between the vertical pixels and the horizontal pixels of the content data 60a, in other words, whether the vertically long content data 60a or the horizontally long content data 60a is mixed, the vertical direction on the display surface 4a The content area of the content file 60 that cannot be displayed at once by making the display area in the (horizontal direction on the display surface 4a) or horizontal direction (height direction on the display surface 4a) constant and set in the vertical or horizontal direction. The content file 60 may be scrolled (sequentially moved).

  Naturally, an example in which the display control unit 49 displays the content file 60 is not limited to the slide show display described above, and a plurality of content files 60 (including a plurality of thumbnail files 61) are simultaneously displayed on one display screen. Also good. As such a display mode, a display similar to an album for pasting a silver salt photograph called a so-called photo book may be displayed. At this time, the display area of each content file 60 on one display screen may be different.

  Here, a specific aspect of the display screen generation signal generated by the display control unit 49 will be described. If the display device 4 that generates the display screen based on the display screen generation signal displays the so-called video signal as it is, the display control unit 49 generates the video signal as the display screen generation signal. . Further, if the display device 4 can generate a display screen by using unique display application software based on the content data 60a and the thumbnail data, the display control unit 49 displays the content data 60a to be displayed on the display device 4. Is also an example of a display screen generation signal generated by the display control unit 49.

  In addition, in the latter case, in response to a request (request) from the display device 4, the display control unit 49 generates a list of content files 60 that match the request, and the display device 4 Based on the list, the content file 60 necessary for performing the slide show display on the display device 4 is selected and requested to the information processing device 1, and the display control unit 49 responds to the request from the display device 4 with the content data. Output of 60a and the like is also an aspect of the display screen generation signal.

  The display control unit 49 preferably generates a display screen generation signal regardless of the operation input received by the input unit 48, and the display screen generation signal regardless of the information received by the communication unit 44. Is preferably generated. In particular, the display control unit 49 of the present embodiment accepts the input unit 48 when the management information detection unit 51 of the capture unit 47 determines that the second management information file 66 is stored in the memory card 7 or the like. Regardless of the operation input, it is preferable to generate the display screen generation signal, and it is preferable to generate the display screen generation signal regardless of the information received by the communication unit 44. As a result, the operation of the information processing apparatus 1 can be locked by connecting the memory card 7 or the like in which the second management information file 66 is stored.

  However, in the present embodiment, in the lock operation described above, in addition to the display screen generation signal generation operation by the display control unit 49, the capture of the second content file 64 and the second management information file 66 by the capture unit 47 is performed. It is preferable to perform a pull-in operation.

  The input I / F unit 42 receives various input signals input to the information processing device 1 from external input devices including the imaging device 3 and the input instruction device 5, and inputs the received input signals to the control unit 40. Accordingly, the data is stored in the storage unit 41 via the control unit 40. The output I / F unit 43 outputs various data in the control unit 40 and the storage unit 41 including a display screen generation signal to an external output device including the display device 4. The communication unit 44 performs communication between each function realizing unit in the information processing apparatus 1 including the control unit 40 and an external device existing on the LAN 11 and the WAN 13.

  In addition, the content file 60 may be stored in the memory card 7 constituting the information processing system S of the present embodiment, and the second management information file 66 may be stored. 3 illustrates an example in which the memory card 7 is connected to the information processing apparatus 1, but the imaging apparatus 3 or the like may be connected as described above. Furthermore, the input instruction device 5 constituting the information processing system S of the present embodiment includes an operation unit 5a that accepts an input operation by a user.

  In the above configuration, the control unit 40 and the capture unit 47, the input unit 48, and the display control unit 49 that constitute the control unit 40 are mainly configured by the CPU 20, and the storage unit 41 is mainly configured by the ROM 21, RAM 22, and HDD unit 26. The input I / F unit 42 is mainly configured by the input / output device 23, the output I / F unit 43 is mainly configured by the HDMI interface 24, and the communication unit 44 is mainly configured by the network interface 25 and the wireless LAN interface 27. Consists of. The operation of each functional unit shown in FIG. 3 will be described in detail later.

(Contents of tag table)
FIG. 6 is a diagram illustrating an example of the contents of the tag table 63 stored in the HDD 261 of the information processing apparatus 1 according to the present embodiment. The tag table 63 of this embodiment includes an album tag table 91 (see FIG. 6A), a content tag table 92 (see FIG. 6B), and an association tag table 93 (see FIG. 6C).

  The album tag table 91 includes an album ID area 91a and an album name area 91b. The album ID area 91a stores an ID number for identifying each album 33, and the album name area 91b stores the name assigned to the album 33 specified by the ID number as text data. .

  The content tag table 92 includes a content ID area 92a, a content file name area 92b, a hash value area 92c, and an imaging time area 92d. An ID number for identifying each first content file 60 stored in the HDD 261 is stored in the content ID area 92a, and the first content specified by the ID number is stored in the content file name area 92b. The file name of the file 60 is stored as text data, the hash value area 92c stores the hash value of the first content file 60, and the imaging time area 92d stores the imaging time data of the first content file 60. Stored. Of these areas 92a to 92d, the data stored in the imaging time area 92d is generated from the information described in the header portion 70 of the first content file 60 described above. Accordingly, what area is provided in the content tag table 92 can be arbitrarily set based on information described in the header portion 90 of the first content file 60.

  The association tag table 93 includes a content ID area 93a and an album ID area 93b. In the content ID area 93a, the ID number of the first content file 60 described in the content ID area 92a of the content tag table 92 is stored, and in the album ID area 93b, the first number specified by this ID number is stored. The ID number of the album 33 associated with the content file 60 is stored.

(Schematic operation of the first embodiment)
Next, a schematic operation of the information processing apparatus 1 according to the present embodiment will be described.

  First, when the imaging device 3 or the memory card 7 is connected to the input I / F unit 42 of the information processing device 1, the medium detecting unit 50 of the capturing unit 47 detects that the memory card 7 or the like is connected. Next, the management information detection unit 51 of the fetch unit 47 determines whether or not the second management information file 66 is stored in the memory card 7 or the like. When the management information detection unit 51 determines that the second management information file 66 is stored in the memory card 7 or the like, the capture unit 47 stores the content file 60 stored in the memory card 7 or the like in the second format. The content file 64 is stored in the temporary storage unit 46. On the other hand, when the management information detection unit 51 determines that the second management information file 66 is not stored in the memory card 7 or the like, the capture unit 47 loads the content file 60 stored in the memory card 7 or the like into the first file. The content file 60 is stored in the storage unit 45.

  For the content file 60 stored in the storage unit 45 or the temporary storage unit 46, the user of the information processing apparatus 1 can set the slide show display. The user uses the input instruction device 5 to set the slide show display.

  Specifically, the user can individually specify the content file 60 to be displayed as a slide show, and can specify the content file 60 for each album 33. Further, the user can set the display time or display interval of each content file 60. In addition, it is possible to set a display effect when the content files 60 are sequentially switched. Furthermore, the enlargement / reduction rate of the content file 60 can be set. In addition, when the content file 60 is displayed on the display surface 4 a of the display device 4, it is possible to set whether or not to scroll-display the area of the content file 60 that cannot be displayed at a time on the display surface 4 a.

  Furthermore, the user can make a setting to automatically display a slide show when the information processing apparatus 1 is activated next time. Such a slide show display is hereinafter referred to as a “home slide show”.

  Data relating to these slide show display settings is stored as management information in the first and second management information files 62 and 66 as display conditions. In particular, in the display conditions forming the management information stored in the second management information file 66, data related to the home slide show setting described above is stored. Therefore, when the second content file 64 (and the second management information file 66) is stored in the temporary storage unit 46, the capture unit 47 stores the content file 60 stored in the imaging device 3 or the like as the second content file 60. When the content file 64 is stored in the temporary storage unit 46, home slide show display based on the second management information file 66 is performed, and when the information processing apparatus 1 is activated, the second stored in the temporary storage unit 46 is displayed. Home slide show display based on the content file 64 is performed.

  As described above, the information processing apparatus 1 according to the present embodiment can lock the operation of the information processing apparatus 1 when the memory card 7 or the like storing the second management information file 66 is connected. If the connection between the card 7 and the like and the information processing apparatus 1 is released, the operation lock of the information processing apparatus 1 can be released.

  In order to store the second management information file 66 in the memory card 7 or the like, the user performs various settings relating to the slide show display described above, and the control unit 40 of the information processing apparatus 1 generates the second management information file 66. In addition, an operation of connecting the memory card 7 or the like that should store the second management information file 66 to the information processing apparatus 1 may be performed. In this way, the second management information file 66 can be stored in the memory card 7 or the like by the control unit 40.

  On the other hand, in order not to use the memory card 7 or the like for the lock operation of the information processing apparatus 1, in other words, to set the unlock operation, the second management information file 66 may be deleted from the memory card 7 or the like. As an example of an operation for deleting the second management information file 66, the user instructs the information processing apparatus 1 to input a setting for performing the second management information file 66 deletion operation, in other words, the unlock operation, in the information processing apparatus 1. After that, when the memory card 7 or the like storing the second management information file 66 is connected to the information processing apparatus 1, the control unit 40 may delete the second management information file 66.

  First, the information processing apparatus 1 is instructed to input a setting for performing the unlocking operation if the memory card 7 or the like storing the second management information file 66 is connected to the information processing apparatus 1. This is because the 47 medium detection unit 50 determines that the second management information file 66 is stored, and as a result, the display control unit 49 automatically performs the locking operation of the information processing apparatus 1.

(Operation of the first embodiment)
Next, the operation of the information processing system S of this embodiment will be described with reference to the flowcharts of FIGS. 7 to 9 are flowcharts for explaining the operation of taking the content file 60 into the information processing apparatus 1 of this embodiment.

  The flowchart shown in FIG. 7 starts when the connection of the memory card 7 or the like to the information processing apparatus 1 is detected. That is, in step S1, the medium detection unit 50 of the capturing unit 47 of the information processing apparatus 1 determines whether or not the memory card 7 or the like is connected to the input I / F unit 42. It is determined that the memory card 7 or the like is connected to the input I / F unit 42, and the program proceeds to step S2.

  In step S2, the management information detection unit 51 of the capture unit 47 determines whether or not the second management information file 66 is stored in the memory card 7 or the like connected to the information processing apparatus 1, and the determination is affirmative. If it is determined that the second management information file 66 is stored in the memory card 7 or the like, the program proceeds to step S11. If the determination is negative, the second management information file 66 is stored in the memory card 7 or the like. It is determined that the file 66 is not stored, and the program proceeds to step S3.

  In step S3, the display control unit 49 of the information processing device 1 generates a display screen generation signal for displaying the capture screen on the display surface 4a of the display device 4, and outputs the display screen generation signal to the output I. The data is transmitted to the display device 4 via the / F unit 43. In step S4, the capturing unit 47 selects one first content file 60 among the first content files 60 stored in the memory card 7 or the like.

  In step S5, the hash value of the content data 60a of the first content file 60 selected in step S4 is calculated. Next, in step S6, the capturing unit 47 stores the hash value of the content data 60a of the first content file 60 stored in the hash value area 92c of the tag table 63 and already stored in the storage unit 45, and The hash value of the content data 60a of the first content file 60 to be imported calculated in step S5 is compared, and it is determined whether or not they match.

  If the determination is affirmative, it is determined that the first content file 60 that is the same as the first content file 60 to be captured is stored in the storage unit 45, that is, has already been captured. The program proceeds to step S8. On the other hand, if the determination is negative, it is determined that the first content file 60 to be captured has not yet been captured, and the program proceeds to step S7.

  In step S <b> 7, the selected first content file 60 is stored in the storage unit 45. In step S9, it is determined whether or not the above-described capturing operation has been performed for all the first content files 60 stored in the memory card 7 or the like. If the determination is affirmed, the program ends and the determination is negative. Then, the program proceeds to step S10, and the capturing unit 47 selects the next content file 60, returns to step S4, and repeats the operations of steps S4 to S7 and step S9.

  On the other hand, in step S8, it is determined that the first content file 60 selected in step S4 is not to be captured, and the program proceeds to step S9.

  On the other hand, in step S <b> 11, the display control unit 49 of the information processing apparatus 1 starts a locking operation that locks the operation of the information processing apparatus 1. Next, in step S12, the display control unit 49 of the information processing device 1 generates a display screen generation signal for displaying the capture screen on the display surface 4a of the display device 4, and the display screen generation signal is displayed. The data is transmitted to the display device 4 via the output I / F unit 43. In step S <b> 13, the capture unit 47 captures the second content file 64 stored in the memory card 7 or the like into the temporary storage unit 46.

  Here, the second content file 64 is stored in a temporary storage unit 46 different from the storage unit 45 in which the first content file 60 is stored, and the connection between the memory card 7 and the information processing apparatus 1 is further established. Since it is deleted from the temporary storage unit 46 when it is released, unlike the first content file 60, without performing the duplicate capture removal operation (operations in steps S4 to S9) to the temporary storage unit 46, All the second content files 64 may be taken in. Of course, the duplicate content removal operation may be performed for the second content file 64 as well.

  In step S14, the display control unit 49 performs a slide show display operation using the second content file 64 captured in step S13. Details of the slide show display operation will be described later.

  Next, FIG. 10 is a flowchart for explaining an example of the operation when the external storage medium connection release is detected in the information processing apparatus of this embodiment.

  The flowchart shown in FIG. 10 is started by detecting disconnection between the information processing apparatus 1 and the memory card 7 or the like. That is, in step S20, the medium detection unit 50 of the capturing unit 47 of the information processing apparatus 1 determines whether or not the connection between the memory card 7 and the input I / F unit 42 is released, and the determination is affirmed. Then, it is determined that the connection between the memory card 7 and the input I / F unit 42 has been released, and the program proceeds to step S21.

  In step S21, if the display control unit 49 is performing a slide show display operation, the slide show display operation is stopped. In step S <b> 22, the capturing unit 47 deletes the second content file 64, the second thumbnail file 65, and the second management information file 66 stored in the temporary storage unit 46. In step S23, the display control unit 49 releases the locking operation.

  Next, FIG. 11 is a flowchart for explaining an example of a slide show display operation of the information processing apparatus according to the present embodiment.

  The flowchart shown in FIG. 11 may be started by an explicit instruction input from the user, and when the information processing apparatus 1 is activated, the data related to the home slide show setting described above is the first or second management information file. If it is described in 62 and 66, the process starts on the condition that data relating to the home slide show setting is described. Further, as described in step S14 described above, when the memory card 7 or the like storing the second management information file 66 is connected to the input I / F unit 42, the second content file 64 or the like is acquired. It starts after the loading operation.

  First, in step S30, the display control unit 49 identifies management information files 62 and 66 that include data relating to the display conditions of the slide show display operation, and the data relating to the display conditions described in the management information files 62 and 66 is obtained. Reading from the storage unit 45 or the temporary storage unit 46. In the following description, the display control unit 49 will be described on the assumption that only one of the first content file 60 and the second content file 64 is the target of the slide show display operation. Needless to say, both the second content file 64 and the second content file 64 may be the targets of the slide show display operation.

  In step S31, the display control unit 49 sets the conditions for the slide show display operation based on the data related to the display conditions read in step S30. Next, in step S32, the display control unit 49 specifies the content file 60 that is the target of the slide show display operation based on the data related to the display condition read in step S30.

  In step S33, one content file 60 is selected from the content files 60 that are identified in step S32 and are the target of the slide show display operation. In step S34, the display is performed based on the slide show display operation conditions set in step S31. The control unit 49 generates a display screen generation signal for generating a display screen on the display surface 4 a of the display device 4, and outputs the display screen generation signal to the display device 4 via the output I / F unit 43. The display device 4 generates and displays a display screen on the display surface 4a based on the display screen generation signal. Since the details of the display mode of the slide show display operation by the display control unit 49 in step S34 are as described above, the description thereof is omitted here.

  In step S35, the display control unit 49 waits for the elapse of the predetermined time and the predetermined time interval based on the slide show display operation condition set in step S31. If the determination is affirmed, the predetermined time and the predetermined time interval have elapsed. Judgment is made, and the program proceeds to step S36.

  In step S36, the display control unit 49 determines whether or not the screen display operation in step S34 has been performed on all the content files 60 that are specified in the slide show display operation specified in step S32. If the determination is affirmed, the program is executed. When the determination is negative and the determination is negative, the program proceeds to step S37, the display control unit 49 selects the next content file 60, returns to step S34, and repeats the operations from step S34 to step S37.

  Next, FIG. 12 is a flowchart for explaining an example of the lock setting operation of the information processing apparatus of this embodiment. The flowchart shown in FIG. 12 is started by an explicit operation start instruction from the user.

  First, in step S40, the user inputs an instruction to start a lock setting operation using the memory card 7 or the like using the input instruction device 5 or the like. In step S41, similarly, the user uses the input instruction device 5 or the like to input and set display conditions for performing a slide show display operation. The setting input in step S41 includes a setting input for the display condition itself and a designation input for the first content file 60 to be the second content file 64.

  In step S42, the control unit 40 generates a second management information file 66 in which data related to the display conditions set and input in step S41 is stored.

  In step S43, it waits for the medium detection unit 50 of the capturing unit 47 to detect the connection to the information processing apparatus 1 such as the memory card 7, and in step S44, the control unit 40 is connected to the information processing apparatus 1. The second management information file 66 generated in step S42 is written to the memory card 7 or the like, and the first content file 60 specified and input in step S41 stored in the storage unit 45 is stored in the memory card 7 or the like. Write to.

  Next, FIG. 13 is a flowchart for explaining an example of the unlock setting operation of the information processing apparatus of this embodiment. The flowchart shown in FIG. 13 is started by an explicit operation start instruction from the user.

  First, in step S50, the user inputs an instruction to start unlocking setting using the memory card 7 or the like using the input instruction device 5 or the like. In step S51, it waits for the medium detection unit 50 of the capture unit 47 to detect the connection to the information processing apparatus 1 such as the memory card 7, and in step S52, the control unit 40 is connected to the information processing apparatus 1. The second management information file 66 stored in the memory card 7 or the like is deleted.
