Hereinafter, processing relating to this image data transfer will be described with reference to the sequence diagram shown in FIG.

  First, when the electronic camera 101 and the PC 201 are USB-connected via the communication line 301 (step S401), the image data transfer process starts.

  When the image data transfer process is started in this way, the PC 201 issues a request for acquiring device information of the electronic camera 101 (information indicating the product name, manufacturer name, and corresponding operation, etc. of the electronic camera 101). It transmits to the electronic camera 101 (step S402A). The electronic camera 101 that has received this device information acquisition request transmits device information to the PC 201 (step S402B).

  Subsequently, in order to start a PTP session, the PC 201 transmits a session start request to the electronic camera 101 (step S403A). Receiving this session start request, the electronic camera 101 prepares for the session and responds with “session start OK” (step S403B).

  Further, the PC 201 transmits an object handle list acquisition request to the electronic camera 101 in order to search for image data recorded in the recording medium unit 103 of the electronic camera 101 (step S404A). Upon receiving this object handle list acquisition request, the electronic camera 101 transmits the object handle list in the electronic camera 101 to the PC 201 (step S404B).

  The object handle is an identifier that is assigned a unique value in the PTP responder device for each object (file or folder such as image data) in the PTP responder device. In PTP, this object is used to manipulate objects such as image data and folders.

  The PC 201 that has received the object handle list transmits an acquisition request for object information associated with the object handle in the acquired object handle list to the electronic camera 101 (step S405A). Upon receiving this object information acquisition request, the electronic camera 101 transmits object information associated with the designated object handle to the PC 201 (step S405B).

  The object information (property of predetermined information) is, for example, when an object is image data, the file name, file size, image size (Height, Width), file format (JPEG, TIFF, etc.) of the image data, These are archive attributes, which will be described later, and information indicating the shooting (acquisition) date and time of the image data. Similarly, for example, if the object is a folder, the object information is information indicating the folder name of the folder, for example.

  The PC 201 that has acquired such object information determines an object (for example, image data) to be acquired based on the object information, specifies an object handle corresponding to the object, and acquires the object to the electronic camera 101. A request is transmitted (step S406A). Receiving this object acquisition request, the electronic camera 101 transmits an object (for example, image data) corresponding to the designated object handle to the PC 201 (step S406B).

  Hereinafter, an example of image data attribute setting in the first embodiment will be described.

  Here, an archive attribute which is one of the attributes of file / directory management of MS-DOS will be described as an example. This archive attribute is set (in other words, turned on) when the file is newly created, changed, or added. When the archive attribute is cleared (in other words, off), it indicates that the file has been backed up.

  In other words, the attribute assigning means included in the CPU 104 has a case where predetermined image data recorded on the recording medium unit 103 of the electronic camera 101 is transferred to the PC 201 by the image data transfer process described above (steps S406A and When the above step S406B is normally completed), the image data related to the image data transfer process is cleared (turned off), that is, a process of giving an attribute indicating transmission is performed. This makes it possible to determine that the image data has already been transferred to the PC 201.

  Incidentally, the electronic camera 101 according to the first embodiment has the following failure prediction function, which is an example of failure prediction means that the CPU 104 has. Hereinafter, an example of this failure prediction function will be described.

  In the first embodiment, for example, when the recording medium unit 103 is a hard disk, a Self-Monitoring, Analysis, and Reporting Technology (hereinafter referred to as S.M.A.R.T.) function is used. .

  Here, S.M. M.M. A. R. T.A. The function is a function for the purpose of hard disk failure prediction or the like. Specifically, the hard disk performs a self-diagnosis and the hard disk host acquires the diagnosis result.

  The items of the diagnosis result include Value (current value), Threshold (threshold value), Worst (worst value), and Data (raw value). Here, when the value of Value or Worst is worse than the value of Threshold, a failure is predicted.

  Furthermore, the items of the diagnosis result include the number of read / write errors, the total number of unrecoverable sectors, the power-on time, and the like. The electronic camera 101 performs failure prediction of the recording medium unit 103 based on the diagnosis result. When it is predicted that the recording medium unit 103 will fail, the CPU 104 displays a warning on the display unit 107 (described in detail with reference to FIGS. 5A to 5E).

  As the timing of this warning display, for example, immediately after the first failure prediction, after it has already been predicted that there is a failure, immediately after the power is turned on, after having already been predicted to have failed, and at the start of shooting, it is predicted that the failure has already occurred. For example, immediately after the image is reproduced and at the start of image reproduction, it is predicted that a failure has already occurred and immediately before the power is turned off.

  Hereinafter, an example of the warning display displayed on the display unit 107 in the first embodiment will be described with reference to FIG.

  Hereinafter, a display example in the case where such a warning display is actually performed on the display unit 107 will be described with reference to FIG.

  FIG. 5A shows that image data in which a failure is predicted by the above-described failure prediction function and the archive attribute is set does not exist in the recording medium unit 103 (in other words, image data that has not been transferred to the PC 201 ( It is a figure which shows the example of a warning display when (untransmitted information) does not exist. In such a case, as shown in the figure, for example, a warning display for notifying the user that there is a possibility that an operation such as “There is a possibility that image recording / playback cannot be performed normally” may not be performed normally is performed. .

  FIG. 5B shows that at least one image data in which the failure is predicted by the failure prediction function and the archive attribute is set exists in the recording medium unit 103 (in other words, untransferred to the PC 201). FIG. 6 is a diagram illustrating an example of a warning display when there is image data (untransmitted information). In such a case, for example, as shown in the figure, unsent information such as “There is a possibility that the image cannot be recorded / reproduced normally” and “There is an image that has not been read and backup is recommended” are included. A warning is displayed to warn the user that it exists and recommends that unsent information be transmitted to the PC 201.

  In such a case, the number and / or size (data amount) of the image data for which the archive attribute is set is further counted by the counting means of the CPU 104, for example, as shown in FIG. As shown in Fig. 4, there is a warning message stating that “There are XX unread images and recommends backup”, and “Unread images are XX kB (MB), not shown. May be displayed.

  By the way, when the user gives a shooting instruction after the warning display as described above is displayed on the display unit 107, for example, as shown in FIG. ”Is displayed indicating that the operation for creating the image data as the predetermined information cannot be performed, and control for prohibiting photographing, that is, prohibiting storage of the image data in the recording medium unit 103 by the storage prohibiting means included in the CPU 104 is prohibited. The storage prohibition warning means of the CPU 104 may warn the user that storage of image data is prohibited.

  Furthermore, when a warning instruction as described above is displayed on the display unit 107 and there is a write instruction (image data editing, image data deletion, etc.) to the recording medium unit 103, for example, FIG. As shown in the above, the display unit 107 displays that the image data recorded in the recording medium 103 such as “cannot edit and delete images” cannot be changed or deleted, and the recording medium unit Control for prohibiting writing to 103, that is, change prohibiting means possessed by the CPU 104 and deletion prohibiting means possessed by the CPU 104 prohibit the change or deletion of the image data stored in the recording medium unit 103, and the CPU 104 has Changing / deleting image data is prohibited by the change prohibition warning means and the deletion prohibition warning means of the CPU 104. It may be carried out to warn the user.

  Further, the software processing prohibiting means possessed by the CPU 104 prohibits execution of software that performs processing for recording image data on the recording medium unit 103 and processing for changing or deleting recorded image data, and prohibits processing performed by the CPU 104. A warning unit may warn the user that execution of the software is prohibited.

  By the way, in the electronic camera 101 according to the first embodiment, when the image data recorded in the recording medium unit 103 is displayed on the display unit 107, that is, when operated by the user, the image related to the display is displayed. When the archive attribute described above is set in the data, information indicating that the image data has not been transferred / transferred is displayed superimposed on the image data. Hereinafter, a description will be given with reference to FIGS.

(When the above archive attribute of image data related to display is cleared)
As shown in FIG. 6A, the message “already transferred” (“COPIED” in the example shown in the figure) is superimposed on the image data and displayed on the display unit 107.

  Alternatively, as shown in FIG. 6B, only the image data is displayed on the display unit 107, and the superimposed display as described above is not performed.

(When the above archive attribute of image data related to display is set)
As shown in FIG. 6C, “not transferred” (“NOT COPIED” in the example shown in FIG. 6) is superimposed on the image data and displayed on the display unit 107.

  By the way, in the first embodiment, the CPU 104 serves as detection means, determines whether image data has not been transferred / transferred based on the archive attribute, and detects untransferred image data as untransmitted information. If the recording medium unit 103 is predicted to fail due to the above-described failure prediction, the CPU 104 displays a warning display and a diagram as shown in FIGS. 5A to 5E based on the detection result. 6 (a) to 6 (c) are superimposed on the display unit 107.

  Hereinafter, an example of image data information recorded in the recording medium unit 103 of the electronic camera 101 will be described with reference to FIG.

  In the example shown in FIG. 7, eight pieces of image data are recorded on the recording medium unit 103, and a file name, an object handle, and an archive attribute are set for each piece of image data as image data information.

  Here, when the electronic camera 101 and the PC 201 are connected after the above-described untransmitted information is detected, the CPU 104 in the electronic camera 101 according to the first embodiment sets (turns on) the archive attribute. The list information creation means of the CPU 104 stores the list information of the object handle corresponding to the stored image data, that is, the unhandled image data, that is, the list information of the untransmitted information. 1st (see FIG. 8) and recorded in the electronic camera 101 (for example, the recording medium unit 103).

  This list file nosave. For example, as illustrated in FIG. 8, lst is a list file including object handles 801 to 806 of image data in which the archive attribute is set.

  The list file nosave. lst may be recorded in the recording medium unit 103 of the electronic camera 101 or may be recorded in the RAM 108 of the electronic camera 101.

  Hereinafter, an image data capturing process (image data transfer process) from the electronic camera 101 to the PC 201 will be described with reference to a sequence shown in FIG. Note that the sequence shown in FIG. 9 is an example of a more specific example of step S405A, step S405B, step S406A, and step S406B in the sequence shown in FIG.

  Similar to the sequence shown in FIG. 4, the transmission / reception control of the image data related to the image data transfer and the control of the electronic camera 101 are performed by the CPU 204 in the PC 201.

  First, when a warning display based on the above-described failure prediction is displayed on the display unit 107, a user who has visually recognized the warning display makes a USB connection between the electronic camera 101 and the PC 201 via the communication line 301 (step S901). ). As a result, the image data transfer process starts.

  When the image data transfer process is started in this manner, the PC 201 issues a request for acquiring device information of the electronic camera 101 (information indicating the product name, manufacturer name, and corresponding operation of the electronic camera 101). It transmits to the electronic camera 101 (step S902A). The electronic camera 101 that has received this device information acquisition request transmits device information to the PC 201 (step S902B).

  Subsequently, in order to start a PTP session, the PC 201 transmits a session start request to the electronic camera 101 (step S903A). The electronic camera 101 that has received this session start request prepares for a session and responds with “session start OK” (step S903B).

  Further, the PC 201 transmits an object handle list acquisition request to the electronic camera 101 in order to search the image data recorded in the recording medium unit 103 of the electronic camera 101 (step S904A). Upon receiving this object handle list acquisition request, the electronic camera 101 transmits the object handle list in the electronic camera 101 to the PC 201 (step S904B).
