Description

  The present invention relates to a data processing device, content management software, and a data processing system.

  In recent years, semiconductor memories such as SD memory cards, memory sticks, and compact flash (registered trademark) have become widespread as nonvolatile storage devices capable of reading and writing digital data. Data processing apparatuses that process data using these semiconductor memories are diverse, including electrical appliances such as personal computers, video equipment, mobile phones, and digital cameras. A nonvolatile storage device that is detachable and excellent in portability, such as a semiconductor memory, is particularly useful as a bridge medium that handles data exchange between data processing devices. Removable non-volatile storage devices as bridge media are often smaller than fixed storage devices such as hard disk drives, so recorded video / audio / still image content is managed as video / audio / still images. In some cases, backup is performed to a larger-capacity fixed storage device in the video / audio image management device which is a data processing device. When performing the backup, the video / audio image management apparatus needs to determine how far the previous backup has been performed and where the content has been newly recorded.

  On the other hand, the detachable nonvolatile storage device is often attached to a plurality of data processing devices. Therefore, data stored in the nonvolatile storage device by a certain data processing device may be updated by another data processing device. For this reason, the data processing apparatus needs to know the difference from the previous mounting when the nonvolatile storage device once removed is mounted again. In a data processing device, in order to determine where the data in the removable nonvolatile storage device has been updated by another data processing device or the like, the data recorded in the removable nonvolatile storage device is used. There has been a problem that it is necessary to actually read and confirm the contents, and that processing time is required as the size of the read data increases. Therefore, as a criterion for identity, in order to narrow down the comparison target, the update date and time recorded on the file system and the EXIF header information of the file are recorded as values that are updated each time content is written to the nonvolatile storage device. For example, the same date / time and file name are used. Alternatively, as described in Patent Document 1, the checksum and CRC of the entire file are calculated and stored in the nonvolatile storage device in the data processing device, and the same is obtained by comparing the checksum or CRC when performing comparison again. A method for determining sex has been proposed.

  However, in this method, when the capture process is performed again after rotating the image in the fixed storage device in the data processing apparatus, the content is recognized as a different content even though it is the same image, and is captured twice.

  In the present invention, in view of the above problems, there is provided a procedure for determining whether or not to capture again based on the processed contents even after the video / audio / image information is processed in the data processing apparatus. Thus, when content stored in a detachable and readable / writable nonvolatile storage device is imported to a fixed storage device in the data processing device, the content is imported again after performing editing operations such as processing or deletion of the content. Provided is a data processing device, a data processing system, and a data processing program that do not simply and repeatedly capture the same content even if it is performed.

A data processing device according to the present invention is a data processing device in which a first nonvolatile memory device and a second nonvolatile memory device are connected, and content is copied from the first nonvolatile memory device to the second nonvolatile memory device. A capturing means for capturing content from the first nonvolatile storage device and recording the content in the second nonvolatile storage device; and editing the content in the second nonvolatile storage device to obtain a second nonvolatile Content editing means for writing back to the storage device and the same information for determining whether the content stored in the second nonvolatile storage device is the same content at the next capture when the content is captured through the capture means When the sex judgment criterion information and the content editing means edit the content, the edition that keeps a history of how the content was edited And a criterion information storage area storing the history information,
The capturing means is configured to transfer content to be captured from the first nonvolatile storage device from the first nonvolatile storage device to the second nonvolatile storage device based on the identity determination criterion information and the editing history information. It is characterized by determining whether to copy the content.

  If the data processing device, content management software, and data processing system according to the present invention are used, processing such as rotating an image on a fixed storage device in the data processing device or deletion is performed, and then the capture processing is performed again. However, since the same image is not repeatedly captured many times, the user's content management can be simplified.

(Embodiment)
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, the nonvolatile memory system according to the present invention will be described. FIG. 1 is a diagram showing a data processing system.

  In FIG. 1, 200 is a digital video recorder which is a data processing device, 100 is a removable first nonvolatile storage device (here, a memory card), and 230 is a second nonvolatile memory built in the data processing device. A storage device (here, a hard disk drive), 400 is an input device (here, a remote controller), 500 is a display device (here, a television), and these are the main components of the nonvolatile storage device system.

  The data processing device 200 can mount the detachable first nonvolatile storage device 100 in the slot 201. The data processing device 200 captures input data from the input device 400 that performs input from the user into the data processing device 200 through the input receiving unit 202. The user can confirm the content of the content displayed on the display device 500, display the progress of processing, and confirm the inquiry content from the data processing device 200 to the user.

  FIG. 2 is a diagram illustrating a functional configuration example of the data processing device 200 which is a digital video recorder. The data processing device 200 includes a slot 201, an input receiving unit 202, a capturing unit 210, an editing unit 220, and a second nonvolatile storage device 230.

  The second non-volatile storage device 230 is the second content storage area 231 that stores the content, and meta information related to the content, and whether or not the content has already been acquired when the content is acquired from the first non-volatile storage device 100 It consists of a criterion information table 240 used to determine

  The capturing unit 210 stores contents such as video / audio / still images stored in the first content storage area 110 of the first nonvolatile storage device 100 connected to the slot 201 in the second nonvolatile storage device 230. This is means for copying the content to the second content storage area 231, that is, for taking in the content. When the content is stored in the second content storage area, identity determination criterion information 260 (details will be described later) that is information for determining the identity of the content is stored in the determination criterion table 240. In this embodiment, the content is taken by an imaging device such as a digital camera, and is a still image stored as digital information in a first nonvolatile storage device. In addition, the capturing unit 210 displays a question sentence such as whether to perform capturing through the display device 500 to a user who is using the data processing apparatus as necessary when performing capture. Display the progress information during import when importing content. When an inquiry as to whether or not to capture is displayed on the display device 500, the inquiry result input by the user through the input device 400 is received via the input receiving unit 202, and the capturing operation is changed. The identity determination criterion information stored in the determination criterion table 240 indicates whether to perform “capture”, “not to capture”, or “determine whether to perform capture after inquiring the user”. Judgment is made based on 260 and editing history information 250.

  The editing unit 220 is a unit that edits the content stored in the second content storage area 231 and writes it back to the second content storage area as necessary. The content processing unit 221 performs rotation, reduction, enlargement, and the like. And content deleting means 222 for deleting the content from the second content storage area 231.

  The content processing unit 221 is a unit that performs rotation, reduction, enlargement, and the like of content from the second content storage area, and writes back the processing result to the second content storage area. As a result of processing, loss of information does not occur, processing that can be completely returned to the original state again is reversible processing, and processing results in loss of information and processing that cannot be restored Use irreversible processing. For example, when rotating the content, if only the value of the orientation information is changed by simply changing the value of the orientation information of EXIF, the content is the same as the content before the processing, and this is a reversible processing. If the JPEG compression of the main unit is released, the video main body is rotated, and the JPEG compression is performed again, so that the pre-processing content cannot be generated based on the processed content, the irreversible processing is there. The content processing means 221 stores in the reversible / irreversible processing information 251 whether reversible processing or irreversible processing has been performed after content processing.

  The content deletion unit 222 is a unit that deletes content from the second content storage area. After the content is deleted, the content deleting unit 222 stores that it has been deleted in the deleted information 252.

  Here, the determination criterion table 240 will be described with reference to FIG. The determination criterion table 240 is a list of contents stored in the second content storage area 231. In this embodiment, the determination criterion table 240 includes a list of storage file names, identity determination criterion information 260, and editing history information 250. .

  The identity determination reference information 260 is used to determine whether or not the content stored in the first content storage area 110 has been copied to the second content storage area 231 in the past. In this embodiment, the determination is made using whether or not the content shooting date and time and the content file size are the same. The shooting date and time and the file size are the shooting date and time and the shooting size of the content at the time of storage in the second content storage area 231, and are not changed even if the file is processed or deleted after storage. When the same date / time and file size of the content to be copied from the first content storage area 110 to the second content storage area 231 are in the identity determination criterion information 260 of the determination criterion table 240, Judge that it has been captured.

  The editing history information 250 records the history when editing operations such as processing and deletion of the content stored in the second content storage area are performed. In the present embodiment, the edit history information 250 includes the reversible / irreversible processing information 251 indicating whether the processing is reversible or irreversible when the content is processed, and the content is deleted from the second content storage area 231. It consists of deleted information 252 indicating the history. The reversible / irreversible processing information 251 manages three states of “not processed”, “reversible processed”, and “irreversible processed”, and the deleted information 252 is “existing” ”And“ Deleted ”are managed, and when the capturing unit 210 captures the content,“ not processed ”and“ exist ”are set, and the editing unit 220 performs processing and deletion. The state is changed.

  FIG. 4 is a diagram showing an operation sequence in which the capturing unit 210 captures data from the first content storage area 110 to the second content storage area 231.

  (S401) A list of contents stored in the first content storage area 110 is acquired from the first content storage area 110.

  (S402) The contents are sequentially extracted one by one from the list of contents acquired in S401.

  (S403) If there is no more content to be extracted from the list in S402, the process ends. If there is, the process proceeds to S404.

  (S404) The identity determination criterion information for determining identity is extracted from the extracted content. Here, the file size and shooting date / time of the content are extracted.

  (S405) The identity determination criterion information 260 is extracted from the determination criterion table 240, and it is searched whether or not there is the same value as the identity determination criterion information acquired in S404, that is, the same shooting date and time and the same file size. When there is no same value, the content has not been stored in the second content storage area 231 in the past, and the process proceeds to S410, and the second content storage area 231 is taken in from the first content storage area 110. . If there is the same value, the content has been stored in the second content storage area 231 in the past, and the process proceeds to S406.

  (S406) The editing history information 250 corresponding to the content for which the same value is found in S405 is extracted from the criterion table 240. Information to be extracted will be described later with reference to FIG.

  (S407) Based on the determination criterion information extracted in S406, it is determined whether or not to take in or whether to inquire the user. The determination sequence will be described later with reference to FIG.

  (S408) If it is determined that the determination result of S407 is not taken, the process returns to S402 and proceeds to the next content. If the user is inquired, the process proceeds to S409.

  (S409) An inquiry screen to the user as shown in FIG. 7 is output to the display device 500, and an input from the user from the input device 400 is awaited. If the user replies that it takes in, the process proceeds to S410. If it is answered that it is not imported, the process returns to S402 and proceeds to the next content.

(S410) The target content to be captured is copied from the first content storage area 110 to the second content storage area 231. Proceed to S 411 after copying (S 411) The identity determination criterion information of the content stored in the second content storage area 231, that is, the shooting date and time and the file size are added to the list of the determination criterion table 240. In addition, the initial value of the editing history information is added. After the addition, the process returns to S402.

  According to the above operation sequence, even if the content in the data processing apparatus is edited and then the capture process is performed again, the same content is not repeatedly captured again and again, thereby simplifying user content management. .

  FIG. 5 shows the details of the sequence for extracting the editing history information in S406.

  (S501) The content having the same identity criterion information, that is, the deleted information 251 regarding the content having the same shooting date and the same file size is extracted from the criterion table 240, and the process proceeds to S502.

(S502) The reversible / irreversible processing information of the content in S501 is extracted.
FIG. 6 shows the details of the determination sequence in S407.

(S601) When the deleted information retrieved in S501 indicates “deleted”, the content to be imported from the first content storage area 110 is content that has been deleted from the second content storage area 231 in the past. Yes, it is determined that the user should be inquired about whether or not to import, and the process proceeds to S605. When “existing” is indicated, the process proceeds to S602. (S602) When the reversible / irreversible processing information taken out at S502 indicates “not processed”, the processing has not been performed in the past. Since the same content as the content to be captured from the content storage area 110 is in the second content storage area, it is determined that the capture is not performed, and the process proceeds to S604. Otherwise, the process proceeds to S603.

  (S603) When the reversible / irreversible processing information in S602 indicates "reversible processing", the content that can be returned to the content to be imported from the first content storage area 110 is the second content storage area In step S604, it is determined that there is no need to capture the information. If “irreversible processing” is indicated, it is determined that the user should be inquired about whether or not to perform capture, and the process proceeds to S605.

  (S604) A determination result not to be taken in is returned, and the process ends.

  (S605) Returns a determination result indicating that the user is inquired about whether or not to import, and ends.

  With the above operation sequence, even if the content in the data processing device is rotated, scaled up, down, etc. or deleted, the same content is repeated over and over again. Since the capturing is not performed, user content management can be simplified.

  As described above, when the data processing device 200 according to the present invention loads content from the removable first nonvolatile storage device 100 to the nonvolatile storage device 230 in the data processing device, the editing history information of the determination criterion table 240 is displayed. A value of 250 is used. As a result, even if the content is imported again after editing operations such as processing and deletion of the content in the first nonvolatile storage device 230, the same content is not simply duplicated.

  Although the present invention has been described based on the above embodiment, it is needless to say that the present invention is not limited to the above embodiment. Various modifications can be made without departing from the spirit of the present invention. The following cases are also included in the present invention.

  (1) Although the present embodiment has been described with a still image, any data may be used as long as it is digitized data. It may be editing of moving image data or music data.

  (2) In the present embodiment, the first nonvolatile storage device 100 is detachable from the data processing device 200, and the second nonvolatile storage device 230 is a fixed storage device in the data processing device. The first nonvolatile storage device or the second nonvolatile storage device may be a NAS (Network Attached Storage) on the network, or may be connected to the outside of the data processing device 200 by a cable such as a USB (Universal Serial Bus). It may be a connected device. The connection form with the data processing device 200 is not limited.

  (3) In this embodiment, the determination criterion table 240 is described in a table format in FIG. 3, but it may be a list structure. Any format is acceptable.

  (4) In this embodiment, the user is inquired as necessary every time one content is extracted from the list in S409. However, the inquiries may be made collectively at the beginning or the end.

  (5) Although the present embodiment has been described using the file size and shooting date / time as information representing the identity of content, a hash value of part or all of a file may be used as a method of representing identity. . If a hash value is used, identity can be determined more reliably. Alternatively, the creation date and update date recorded in the directory entry of the file system such as FAT may be used. By using the creation date / time and update date / time recorded in the directory entry of the file system, the identity determination information can be acquired at a higher speed than in the embodiment.

  (6) In the present embodiment, the deleted information 252 has two states of “deleted” and “exists”, but “deleted” “exists” “deleted in a recoverable state”. Two or more states may be held such as three states.

  (7) In this embodiment, the editing means is composed of the content processing means and the content deletion means. However, other editing means such as content dividing means and content copying means may be included. The moving image content is divided at the position designated by the user into two contents, or the same content is duplicated to make two or more contents, which are recorded in the editing history information 250, and based on the information It may be determined whether or not the capture is performed again.

  The data processing device, the data processing system, and the data processing program according to the present invention avoid duplication that is not intended by the user along with editing operations such as processing and deletion when copying content between two data processing devices, A simple content management method has been proposed, which is useful in still image management devices, moving image management devices, digital video recorders, and mobile phones that exchange data between two nonvolatile storage devices.
