Description

  The present invention relates to an information processing method for transferring data recorded on a recording medium to another removable recording medium.

  Imaging devices such as digital cameras include a type that records captured still images or moving images on a removable storage medium, a type that records them on a built-in large-capacity recording medium, or a type that combines these types.

  In addition, in a recording / reproducing apparatus in which a plurality of recording media can be mounted, data can be transferred or copied between the plurality of recording media. For example, when copying data, it is possible to transfer or copy a selected file every time one file is selected, or to transfer or copy a plurality of preselected files or all files at once.

  It is also known to sequentially reproduce a plurality of image data in accordance with control information called a DPOF file recorded on a recording medium (see Patent Document 1).

Also, using such DPOF, it is possible to perform a slide show of a plurality of images and automatic transfer to an external device.

  In recent years, the capacity of hard disks (HDDs) has been increased, and the capacity is much larger than the capacity of memory cards that are generally used. However, when the amount of data to be transferred or copied increases, the remaining capacity of the copy destination memory card is easily exceeded.

  In such a case, for example, a plurality of detachable recording media must be prepared, and data corresponding to the recordable data amount must be selected in accordance with the remaining capacity of the recording medium. This complicates the operation and is very inconvenient.

  In addition, even when information that specifies data to be transferred or reproduced in advance, such as DPOF, is intended to be used after data transfer, the transfer destination storage medium is divided into a plurality of parts. There was no way to use information. In particular, when a playback order or the like is determined in advance, such as a slide show, the playback order set in advance cannot be used after data transfer.

  The present invention is to solve these problems.

In particular, by selecting a plurality of data to be transferred or copied in advance, the complexity of the selection operation is reduced, and the data can be easily transferred or copied.
It is another object of the present invention to make it possible to utilize a predetermined order even after data transfer.

  An information processing apparatus for solving such a problem is attached to a mounting unit from among a mounting unit that detachably mounts a storage medium, a memory that records a plurality of data, and data recorded in the memory. Selecting means for selecting a plurality of data to be transferred to the storage medium; and recording control means for recording in the memory first control information describing specific information for specifying the plurality of data selected by the selecting means; When the remaining capacity of the mounted storage medium is insufficient to record all of the data specified by the control information, the data of the capacity that can be recorded in the storage medium mounted in the mounting unit is stored from the memory. And transferring means for creating second control information in which information specifying the transferred data is described and transferring it to the storage medium.

  According to the present invention, even if there is a large amount of data to be transferred and the remaining capacity of the storage medium of the transfer destination is exceeded, the complexity of the selection operation is reduced by selecting a plurality of data to be transferred in advance. At the same time, the selected data can be easily transferred and copied. In particular, the operability is improved when a plurality of data to be transferred is dividedly recorded on a plurality of storage media.

  Furthermore, control information for specifying data to be transferred can be utilized even after data transfer.

  In particular, when the playback order is determined in advance, the playback order can be used even after data transfer.

Example 1
FIG. 1 shows a system diagram for realizing the present invention. Here, a digital camera (hereinafter referred to as a camera) will be described as an example. However, the present invention is not only applicable to cameras, but can be applied to an information processing apparatus that handles various types of data and can transfer and copy data on other recording media.

  The camera (100) includes a system controller (101) that controls the system and blocks that process each function. The system controller 101 can perform recording control for recording image data and system files, which will be described later, on the recording medium 105, reading control for reading data from the recording medium 105, and the like.

  When recording an image using a digital camera, first, external light that has passed through the imaging unit (102) (comprising an optical system, a motor for controlling the optical system, and an imaging device) is on the surface of the imaging device. An optical image is formed on this and converted into an electric signal by the image sensor. The optical system of the imaging unit includes a lens and a shutter. In addition, a CCD, a CMOS, or the like can be applied as the imaging element. The electrical signal from the image sensor is converted into digital data by the image / sound processor (103). The image / audio processing unit may be a processing circuit configured by hardware, or a CPU that operates according to an application for image / audio processing. In this case, the application for image / audio processing is stored in the built-in memory 107. The digital data is recorded on a removable storage medium (105) (hereinafter referred to as a storage medium) attached to the camera body via the storage medium interface (104). The mounting state of the storage medium is detected by the storage medium detection unit (106). The digital data can be recorded in the memory (107) in the camera body according to the camera settings.

  When the data recorded in the storage medium 105 is reproduced, the data read from the storage medium 105 via the storage medium interface 104 is converted into data suitable for display by the image / audio processing unit and then displayed on the display unit (108). ) Is displayed. The data recorded in the memory (107) in the camera body can also be displayed on the display unit (108) after being converted into data suitable for display by the image / audio processing unit (103).

  The user can operate the camera through the user operation unit (110). The audio output unit (109) can output a warning sound for notifying the user of the internal state of the camera and sound during video reproduction. At the same time, warnings and camera operating states can be displayed on the display unit.

  FIG. 11 is an example of a list file to be described later. The list file describes information for specifying data to be transferred or copied, and functions as control information for the apparatus to perform transfer processing according to the list file.

Here, a DPOF file generated for automatic transmission is used. In the case of this DPOF file, the images to be automatically transmitted are described by specific information for specifying data, such as 1102 and 1104, respectively. here,
. . / DCIM / 100ABCDE / ABCCD0001. JPG
. . / DCIM / 100ABCDE / ABCD0003. JPG
The two lines indicated by are data to be transmitted. This means that there is a directory called “DCIM”, and there is a further directory called “100ABCDE” within which a file name “ABCD0001.JPG” or “ABCD0003.JPG” is designated as a transfer target. Is shown.

  It is also possible to designate moving image data, text data, or the like instead of the file name “ABCD0001.JPG” or “ABCD0003.JPG”.

  Reference numerals 1101 and 1103 denote IDs assigned to each JOB. In this apparatus, the data transfer order is determined using the number information assigned to this ID.

  The more data selected to be transferred or transmitted, the longer this list file is written, and the larger the number assigned to the ID. For example, when a total of 100 data including moving images and still images are to be transferred, IDs 1 to 100 are allocated.

  It is also possible to define the playback order of the slide show display and the print order when printing using the ID number information. In addition, in order to be able to utilize this preset ID order even after data transfer, a new list file is generated and the transferred data is recorded together when data is transferred or copied. I will do it.

  That is, when the data transfer can be performed from ID = 001 to 010, the list file having the ID = 001 to 010 is recorded on the transfer destination recording medium.

  In the present apparatus, the ID starts from 001. However, 000 or other predetermined numbers determined by the apparatus may be used as the first number.

  FIG. 2 is a sequence in the case of registering selected data as a transfer target in a list file.

  With the camera displaying data (for example, still image or moving image data) recorded in the memory 107 in the playback mode on the display unit 103, the operation unit 110 is used to select desired data.

  Here, for example, when a moving image file is selected and a selection operation as a transfer target is performed by the user, it is confirmed whether a list file exists in the memory 107 (S202).

  If the list file does not exist, a new list file is created in the memory 107 (S203). If the list file exists, the file is opened (S204).

  The moving image file in the display selection state is registered by additionally writing to the list file (S205).

  In the present embodiment, the transfer process does not mean only the process of erasing the transfer source data and moving the data, but may be a data copying process.

  FIG. 3 is a sequence of transferring data (moving image file or still image file) registered in the list file in the memory 107 to the removable recording medium 105 from the memory 107 in the camera body.

  This sequence can be executed when the camera is set to the transfer mode and the list file for specifying the transfer target data is already in the memory 107. When the display state as shown in FIG. It is executed by a user operation.

  First, the storage medium detection unit (106) confirms whether a detachable recording medium is inserted into the storage medium IF as the storage medium mounting unit (S301).

  If a recording medium is loaded, the remaining capacity (free capacity) of the storage medium is confirmed (S302), and it is confirmed that a list file exists in the camera body built-in recording medium (S303).

  Next, the list file in the memory 107 in the camera body is opened and the total capacity of the transfer target data registered in the list file is confirmed (S304).

  It is confirmed whether or not the remaining capacity of the removable recording medium 105 is larger than the total capacity of the data to be transferred (S305).

  When the free capacity of the removable recording medium is smaller than the total capacity of the transfer target data, all the transfer target data is transferred to the storage medium 105 (S306).

  When the free capacity of the removable recording medium is larger than the total capacity of the transfer target data, the transfer target data is transferred in the order of the IDs 1101 and 1103 until the remaining capacity of the mounted storage medium 105 runs out. (S307).

  While data is being transferred to the storage medium 105 in S306 and S307, the display is as shown in FIG.

  A list file for specifying the data transferred at this time is also generated and recorded on the recording medium.

  For example, when data of ID = 001 to 010 can be transferred among the data to be transferred by the list file, a list file having this ID = 001 to 010 is newly created and the transfer destination is recorded. Record on media. As a result, even in the recording medium, the order created at the transfer source can be used for processing related to the order such as a slide show.

  If the transfer is completed until there is no remaining capacity, it is confirmed in S308 whether all the transfer target data described in the list file has been transferred.

  If untransferred data exists among the data specified in the list file, the process proceeds to the process of FIG. 4 in step S309.

  If all the data specified in the list file has been transferred to the storage medium 105, the process is terminated.

  FIG. 4 shows a process when the detachable recording medium has insufficient free space in S309 of FIG.

  This is a sequence in which data transfer is performed until there is no remaining capacity (empty capacity) of the removable recording medium, and then data transfer is continued to another removable recording medium.

  First, in S400, as shown in FIG. 10, a guidance message for prompting replacement of the recording medium is displayed on the display unit.

  Thereafter, it is confirmed whether a new detachable recording medium has been inserted into the storage medium IF 104 as a storage medium mounting unit (S401).

  When a new storage medium is loaded, the free space of the recording medium is confirmed (S402), and transfer processing is performed for untransferred data among the data specified in the list file (S403).

  Also at this time, similarly to S307, a list file for specifying data that can be transferred among the data to be transferred by the list file is created and recorded on the recording medium. For example, if the original list file ID = 011 to 030 can be transferred in S403, a list file for specifying these 20 data is created. However, the first number of the UD is reset, and a list file having ID = 001 to 020 is newly created and recorded on the transfer destination recording medium. As a result, the recording medium can use the order created at the transfer source, and can prevent a list starting from a halfway number from being suddenly created.

  In S404, it is confirmed whether all the transfer target data described in the list file has been transferred. If not completed, the process returns to S400.

  FIG. 5 is a display example of the display unit 108 displaying a list of a plurality of moving image thumbnails (moving image thumbnails 1 to 5) and still image thumbnails 1 for each chapter. A thumbnail displayed in a thick frame (501) is currently selected. In the example, the moving image thumbnail 1 is selected. Here, the moving image thumbnail is obtained by reducing the top image of the chapter. However, the video thumbnail is not limited to the top image, and may be created from any of the scenes included in the chapter, or may be an animation or an icon representing the chapter. The still image thumbnail is generated by reducing the still image. However, the still image thumbnail is not limited to this and may be an animation or an icon indicating the still image. However, it is convenient for both the moving image thumbnail and the still image thumbnail that can recognize the contents of the original image.

  In addition to the thick frame as described above, as long as the display form can recognize the selected image, the background color may be changed, or the selected image may be displayed larger.

  FIG. 6 is a display example in which the moving image thumbnail 2 displayed in a thick frame is selected and registered in the list file or finally confirmed by the user.

  In this display state, when the user operates, for example, a determination button on the operation unit, a process of registering a moving image file corresponding to the moving image thumbnail 2 in the list file as a transfer target (FIG. 2) is performed.

  FIG. 7 shows a display example when registration of the selected data in the list file is completed.

  In the above embodiment, a DPOF file is used as a list file. However, a moving image playlist file can also be applied as a list file.
