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). The electronic camera 101 that has received this session start request prepares a session and responds with “session start permission (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.

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

  FIG. 5A shows a predetermined time (for example, “one month” etc.) after the above-described archive attribute is set (ON) and acquired by photographing or the like, for example, recorded on the recording medium unit 103; The electronic camera 101 can automatically set it according to the size of image data that can still be recorded in 103, or can be arbitrarily set by the user). FIG. 5 is a diagram showing an example of a warning display displayed on the display unit 107 of the electronic camera 101 when at least one or more image data (untransmitted information) exists in the recording medium unit 103 detected by the detection means having is there. In such a case, for example, as shown in the figure, it is recommended that there is untransmitted information such as “Recommend backup because there is an image that has not been read”, or that untransmitted information is transmitted to the PC 201. A warning is displayed to warn the user to that effect.

  Further, the count means of the CPU 104 counts the number and / or size (data amount) of image data for which a predetermined time has elapsed since the above-mentioned archive attribute is set and acquired by photographing or the like. For example, as shown in FIG. 5B, for example, there is a warning display stating “There are XX unread images and backup is recommended”, or “not read out images not shown”. A warning message stating that “○ kB (MB) exists and recommends backup” may be displayed.

  In addition, for example, when the archive attribute is set and the total number of image data that has passed a predetermined time since being acquired by shooting or the like is equal to or greater than a predetermined number of image data (data amount), Of course, a warning display as shown in FIG. 5A or FIG.

  By the way, the timing for performing the warning display as described above is, for example, immediately after it is determined for the first time that there is image data that has passed for a predetermined time since being acquired by shooting or the like, for a predetermined time after being acquired by shooting or the like After determining that there is image data that has passed, and immediately after turning on the power, after determining that there is image data that has passed a predetermined time after being acquired by shooting or the like and at the start of shooting, Image data that has been determined that there is image data that has been acquired for a predetermined time or more after being acquired by shooting or the like and that has been acquired for a predetermined time or more at the start of image reproduction or acquired by shooting or the like For example, it is after it is determined that it exists and immediately before the power is turned off. Note that these timings are merely examples, and it may be configured so that the user can set any timing and display warnings as appropriate.

  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. Based on the setting / clearing of the archive attribute described above in the data, information indicating that the image data has not been transferred / transferred to the PC 201 is superimposed on the image data and displayed on the display unit 107. 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.

  Here, the superimposed display is performed when a predetermined time or more has elapsed since the image data was acquired by photographing. For example, when the predetermined time is zero, immediately after the image data is acquired by photographing or the like. In addition, information indicating whether or not the image data has been transferred to the PC 201 (whether or not backup has been performed) can be superimposed and displayed immediately after acquisition, as shown in FIGS. it can.

  The CPU 104 determines whether the image data has not been transferred / transferred based on the archive attribute, and whether or not a predetermined time has elapsed since the image data was acquired by shooting or the like.

  That is, in the first embodiment, the detection unit of the CPU 104 determines whether image data has not been transferred / transferred based on the archive attribute, and a predetermined time or more has elapsed since the image data was acquired by shooting or the like. The image data that has not been transferred and has passed for a predetermined time or more is detected as untransmitted information. Then, based on the detection result, the CPU 104 displays a warning display as shown in FIGS. 5A and 5B and a superimposed display as shown in FIGS. 6A to 6C. To do. Whether or not a predetermined time or more has elapsed since the image data was acquired is determined from the date and time when each image data was acquired by photographing and the current date and time from the date and time when the image data image was acquired to the current date and time. Determination is made by calculating the elapsed time by the calculation means of the CPU 104.

  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 image creation data, that is, the list file of the object handle corresponding to the non-captured image data, that is, the list information in which the untransmitted information is listed, is stored in the nosave. 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.
