Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a data file copying apparatus for copying a data file between recording media, for example, a primary recording medium for recording an image data file photographed by a digital camera or captured by a scanner, and such an image data file. The present invention relates to an apparatus for copying a data file to and from a secondary recording medium capable of recording a large amount of files.
[0002]
[Prior art]
2. Description of the Related Art In a conventional digital camera (hereinafter sometimes abbreviated as a digital camera), a memory built in a camera body or a memory card that is detachable from the camera body is used as a recording medium.
[0003]
When a removable memory card is used as a recording medium, it is possible to change the memory card one after another, take a picture, and carry the image data file. Similarly, in an image reading device such as a scanner, a read image data file can be stored in a memory card and carried.
[0004]
By the way, when storing or editing an image data file taken by a digital camera or read by a scanner, the image data file is stored on a large-capacity recording medium (for example, CD-R, DVD-R, hard disk drive, etc.). It is common to copy and work.
[0005]
However, image data is transferred between a primary recording medium such as an SD card (Secure Digital Memory Card) and a secondary recording medium such as a CD-R, DVD-R, or hard disk drive capable of recording a large amount of image data. In a conventional data file copying apparatus capable of copying a file, when an attempt is made to copy an image data file from a primary recording medium to a secondary recording medium, the same image data is already copied to the secondary recording medium. In spite of the existence of the file, there is a possibility that the same image data file is redundantly stored in the secondary recording medium.
[0006]
Further, when a process such as image editing is performed on an image data file after photographing, the original image data file recorded on the secondary recording medium may be overwritten and deleted.
[0007]
Conventionally, various techniques have been proposed to avoid such inconveniences. For example, there is disclosed a technology in which a counter that counts up for each photographing is provided in a photographing device and a file name is generated based on the counter value so that file names are not duplicated as long as the same photographing device is used. (For example, see Patent Document 1).
[0008]
Also, unique identification information is assigned to each primary recording medium, and when copying a data file to the secondary recording medium, a directory is created on the secondary recording medium based on the identification information of the primary recording medium, and the directory is created. A technique has been disclosed in which a data file is copied into a directory to ensure the uniqueness of the data file on the secondary recording medium (for example, see Patent Document 2).
[0009]
Also, when recording an image data file with a digital camera, a unique ID different for each image data file is recorded as a file attribute, and when copying the image data file from the primary recording medium to the secondary recording medium, the unique ID is recorded. Are compared to detect the identity of image data files (for example, see Patent Document 3).
[0010]

JP 2001-144921 A
[Patent Document 3]
JP-A-11-234615
[0011]
[Problems to be solved by the invention]
However, in the technology described in Patent Document 1, since the identity of data files is managed within the range of image data files generated by the same image capturing device, image data files generated by a plurality of image capturing devices will be managed. Then, the uniqueness of the data file cannot be ensured only by the file name.
[0012]
More specifically, as shown in FIG. 10, in the digital camera A, a file name “XXX00001.JPG” is given to an image data file having a counter value of “1”, and the counter value is “2”. When a file name is given according to the counter value, such as giving a file name “XXX00002.JPG” to a certain image data file, the counter value is similarly “1” in the digital camera B as well. The file name “XXX00001.JPG” is given to the image data file.
[0013]
Therefore, the file name corresponding to the counter value “1” in the digital camera A and the file name corresponding to the counter value “1” in the digital camera B are both “XXX00001.JPG”. could not.
[0014]
Further, in the technique described in Patent Document 2, since the uniqueness of the image data file is managed in the management directory for storing the image data file, the management directory name must be considered in order to manage the image data file. Must.
[0015]
More specifically, as shown in FIG. 11, a plurality of management directories such as directory A, directory B, directory C,... Are provided in the secondary recording medium, and file management is performed for each management directory. , Data files “XXX00001.JPG”, “XXX00002.JPG”,... Are created in the directory A, and “XXX00001.JPG”, “XXX00002.JPG”,. May be created.
[0016]
In this case, image data files having the same file name “XXX00001.JPG”, “XXX00002.JPG”,... Exist in both the directory A and the directory B, and the image data files are managed. In doing so, it is necessary to perform management including the management directory name.
[0017]
Further, in the technique described in Patent Document 3, when recording an image data file (at the time of shooting), a unique ID that differs for each image data file is recorded as a file attribute. It is assumed that the above-mentioned correspondence is made, and cannot be applied to an image data file recorded by a photographing apparatus that cannot record a unique ID.
[0018]
More specifically, as shown in FIG. 12, in an image data file photographed by a digital camera capable of recording a unique ID called unique number A, an image data file “XXX00001.JPG” has a unique number A- 1 is assigned, and a unique number A-2 is assigned to the file “XXX00002.JPG”. On the other hand, in the case of an image data file photographed by a digital camera that cannot record a unique ID, the unique ID is not given. Therefore, the image file names are “XXX00001.JPG” and “XXX00002.JPG”, It is not possible to manage the image data file based on it.
[0019]
The present invention has been proposed in view of the above circumstances, and when copying a data file from a primary recording medium to a secondary recording medium, prevents the same data file from being duplicated, It is another object of the present invention to provide a data file copying apparatus between recording media that can reliably protect an original data file even when a data file is processed.
[0020]
[Means for Solving the Problems]
The data file copying device between recording media according to the present invention has the following features in order to achieve the above object.
[0021]
That is, a data file copying device between recording media according to the present invention, a code attaching means for attaching a unique code different for each recording medium of the transfer source to the data file,
When copying the data file recorded on the recording medium of the transfer source to the recording medium of the transfer destination, the data file recorded on the recording medium of the transfer source and the data file recorded on the recording medium of the transfer destination are copied. Discriminating means for discriminating whether or not the data files recorded on both recording media are the same by comparing a time stamp, a data size, and the unique code. .
[0022]
In the data file copying device between recording media having such a configuration, a code unique to each transfer source recording medium is assigned to the data file by the code assigning means. When copying a data file from a recording medium of a transfer source (for example, a memory card of a digital camera) to a recording medium of a transfer destination (for example, a CD-R, a DVD, a hard disk drive, or the like), the discriminating means uses The unique code is compared with the file time stamp and data size to determine the identity of the data files recorded on both recording media. Therefore, the identity of the data files can be reliably and easily determined.
[0023]
Further, the code assigning means can be configured to assign the unique code to the data file when the data file is recorded on the recording medium of the transfer source.
[0024]
In a data file copying apparatus between recording media having such a configuration, for example, an image data file is photographed with a digital camera capable of giving a unique code, and is used when recording an image data file on a memory card. Is given. For this reason, if the transfer source device has a function of assigning a unique code to the data file, the identity of the data file can be reliably and easily determined.
[0025]
Further, the code adding means may be configured to add the unique code to a data file read from the transfer source recording medium when copying the data file to the transfer destination recording medium. It is possible.
[0026]
In a data file copying device between recording media having such a configuration, for example, even if the digital camera does not have a function of adding a unique code to the image data file, the image data file recorded on the memory card Is copied to a hard disk drive or the like, a unique code is added to the image data file. For this reason, even if the transfer source device does not have a function of assigning a unique code to the data file, the identity of the data file can be reliably and easily determined.
[0027]
Further, when the determining means determines that the data file recorded on the recording medium of the transfer source and the data file recorded on the recording medium of the transfer destination are the same, the copying of the same data file is performed. If the data file recorded on the recording medium of the transfer source is not determined to be the same as the data file recorded on the recording medium of the transfer destination, the non-identical data file is copied. It is possible to configure.
[0028]
In a data file copying apparatus between recording media having such a configuration, for example, when copying an image data file recorded on a memory card by photographing with a digital camera to a hard disk drive or the like, the same image data file Is not duplicated. Therefore, the data file can be easily managed, and the recording area of the recording medium at the transfer destination can be effectively used.
[0029]
When the determining means determines that the data file recorded on the recording medium of the transfer source and the data file recorded on the recording medium of the transfer destination are the same, the same data file is copied. Equipped with confirmation means for confirming whether or not to
It can be configured to determine whether to copy the same data file based on a result of the confirmation by the confirmation means.
[0030]
In a data file copying apparatus between recording media having such a configuration, for example, when copying an image data file recorded on a memory card by photographing with a digital camera to a hard disk drive or the like, the same data is recorded on both recording media. If there is an image data file having the file name of, the checking means checks whether or not to copy the image data file, and overwrites the image data file, cancels the copy, or changes the file name. You can choose to change and copy. Therefore, the same data file is not duplicated, the data file can be easily managed, and the inconvenience of precious data file being overwritten and copied against the user's intention is solved. can do.
[0031]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a data file copying apparatus between recording media according to the present invention will be described with reference to the drawings.
[0032]
FIG. 1 is a schematic diagram showing a configuration of a transfer source recording medium (hereinafter, referred to as a primary recording medium) used in a data file copying apparatus between recording media according to an embodiment of the present invention.
[0033]
The primary recording medium used for the data file copying device between recording media according to the embodiment of the present invention is, for example, a memory card capable of recording an image data file or the like.
[0034]
As shown in FIG. 1, the memory card 101 has a non-rewritable area 101A and a rewritable area 101B. In the non-rewritable area 101A, a unique ID (for example, “123ABC”) and attribute information such as recording capacity and transfer speed are recorded, and in the rewritable area 101B, management information and this management information are managed. Image data files are recorded.
[0035]
The contents of the image data file will be described later in detail. In the example shown in FIG. 1, the data recorded in the rewritable area 101B is an image data file, but another data file such as a music data file can be recorded.
[0036]
The memory card 101 can be mounted on a device such as a digital camera to record an image data file or the like.
[0037]
Next, an apparatus for recording a data file on a primary recording medium in a data file copying apparatus between recording media according to an embodiment of the present invention will be described. In the following description, a digital camera will be described as an example of a device for recording a data file on a primary recording medium. However, a device for recording a data file on a primary recording medium is not limited to this. And other devices such as a scanner.
[0038]
FIG. 2 is a block diagram illustrating a schematic configuration of the digital camera.
[0039]
As shown in FIG. 2, the digital camera 201 includes a control unit 202, a photographing unit 203, an input unit 204, a card slot 205, and a photographing switch 206.
[0040]
The control unit 202 performs processing when the shooting switch 206 is operated, and also operates a mode dial (not shown) for selecting a shooting mode, a playback mode, etc., a multi-function cross key, a power switch, a shooting switch, etc. It receives from the input unit and performs processing corresponding to each input.
[0041]
When the photographing mode is selected and the photographing switch 206 is operated, the control unit 202 detects this, performs focus control and exposure control based on the photometry value and the distance measurement value, and stores the image photographed by the photographing unit 203 in the data. Is converted into an image data file, and the image data file is recorded on the memory card 101 inserted in the card slot 205. That is, image data obtained at the time of shooting is recorded in the rewritable area 101B of the memory card 101 as an image data file.
[0042]
Next, the configuration of the image data file in the memory card 101 will be described. FIG. 3 is a schematic diagram showing a configuration of an image data file in a memory card.
[0043]
As shown in FIG. 3, in the digital camera 201, for example, 100 image data files can be recorded on the memory card 101. Each image data file stores identification information and image data compressed according to the JPEG standard. This identification information includes at least the unique ID of the memory card, the shooting time (time stamp), and the data size. FIG. 3 shows an example of an image data file that can be recorded on the memory card 101, and does not limit the number of recordable files or the file format.
[0044]
Next, an image recording operation in the digital camera 201 will be described with reference to FIG. FIG. 4 is a flowchart illustrating a procedure of an image recording operation in the digital camera.
[0045]
In order to record an image in the digital camera 201, first, it is determined whether or not the memory card 101 is inserted in the card slot 205 of the digital camera 201 (S401). Indicates that the digital camera 201 is in a photographable state (standby state) (S402).
[0046]
When the photographing switch 206 is operated (ON) (S403), the control unit 202 reads out the unique ID from the memory card 101, creates identification information along with a time stamp and data size (S404), and acquires an image of the photographed frame. The data is recorded on the memory card 101 together with the data (S405).
[0047]
Here, the image data file name is assigned the latest number of, for example, “XXXX00001.JPG to XXXX99999.JPG”. If the file name is unique in the memory card 101 at the time of file creation, The method for creating a file name is not particularly limited.
[0048]
In the present embodiment, a time stamp and a data size are provided as identification information along with a unique ID for each recording medium (memory card 101), and the uniqueness of the data file is ensured based on the identification information. Therefore, unlike the conventional technique shown in FIG. 10, there is no inconvenience that the file names of image data files photographed by a plurality of digital cameras are duplicated and uniqueness cannot be secured.
[0049]
Here, when the digital camera does not support reading and writing of the unique ID, the identification information is created without reading the unique ID. The details of the identification information creation processing will be described with reference to FIG. FIG. 5 is a flowchart showing details of the identification information creation processing (S404 shown in FIG. 4).
[0050]
In the identification information creation process, the creation procedure of the identification information differs depending on whether the unique ID can be read (S501). That is, if the digital camera 201 can read the unique ID, the digital camera 201 reads the unique ID into the memory card 101 (S502) and creates identification information including the unique ID (S503). On the other hand, if the digital camera 201 cannot read the unique ID, it creates identification information that does not include the unique ID (S504).
[0051]
Next, a description will be given of a management / reproducing apparatus which can handle the memory card 101 recording an image data file captured by the digital camera 201 as a primary recording medium and having a hard disk drive as a secondary recording medium. I do.
[0052]
The management / playback apparatus and a means for assigning a unique ID (for example, the control unit 202 in the digital camera 201) constitute a data file copying apparatus between recording media according to the embodiment of the present invention.
[0053]
FIG. 6 is a block diagram showing a schematic configuration of a reproduction / management device which is one component of the data file copying device between recording media according to the embodiment of the present invention. In the example shown in FIG. 6, a playback / management device that can handle two recording media is shown. However, the number of recording media that can be handled is not limited to two. May be configured so that three or more recording media can be handled as long as the recording medium can copy the same.
[0054]
As shown in FIG. 6, the playback / management device 601 includes a control unit 602, a main memory 603, an input unit 604, an output unit 605, a PC card slot 606, and a hard disk drive 607.
[0055]
The playback / management device 601 can handle the memory card 101 as a primary recording medium by attaching the memory card 101 to the PC card 609 and further attaching the PC card 609 to the PC card slot 606. The hard disk drive 607, which can record a large amount of image data files, is the secondary recording medium. The data file can be copied between the memory card 101 and the hard disk drive 607. Further, it is also possible to reproduce data files recorded on the memory card 101 and the hard disk drive 607.
[0056]
Note that the card slot for handling the primary recording medium is not limited to the PC card slot 606, and may be a card slot for another removable recording medium. Further, another removable recording medium or a fixed recording medium may be connected without using a card slot.
[0057]
As the primary recording medium or the secondary recording medium, a disk-shaped removable recording medium such as a CD-RW, a DVD-RAM, a DVD-RW, a DVD + RW, a flash memory, a compact flash (registered trademark), a smart media, and a memory stick , A removable recording medium such as an SD card may be used.
[0058]
The hard disk drive 607 has a recording capacity capable of storing a large number of image data files, and the main memory 603 stores software and the like necessary for starting and operating the playback / management device 601.
[0059]
The control unit 602 performs necessary processing on the input unit 604 based on an input operation from a remote controller or the like.
[0060]
Further, the output unit 605 displays an image data file or the like stored in the hard disk drive 607 or the memory card 101 on the monitor 608 by processing in the control unit 602.
[0061]
Next, an operation when the image data file is copied from the memory card 101 storing the created image data file to the hard disk drive 607 of the playback / management device 601 will be described. FIG. 7 is a flowchart showing an operation procedure when copying an image data file from a memory card to a hard disk drive.
[0062]
To copy an image data file from the memory card 101 to the hard disk drive 607, first, as shown in FIG. 7, the control unit 602 inserts the PC card 609 with the memory card 101 into the PC card slot 606. It is determined whether or not it is (S701).
[0063]
Here, when the PC card 609 is inserted into the PC card slot 606, the information recorded in the memory card 101 is read automatically or by the user performing a remote control operation. On the monitor to select whether to copy the image data file stored in the monitor. Then, the user performs a remote control operation according to the guidance displayed on the monitor to determine whether or not to copy (S702).
[0064]
Here, if the copy is not performed, the process is terminated. On the other hand, when copying is performed, the control unit 602 reads an image data file from the rewritable area 101B of the memory card 101 (S703). Then, when the image data file is read, it is checked whether or not the unique ID is included in the identification information of the image data file (S705).
[0065]
Here, when the unique ID is not included, the unique ID of the memory card 101 is read, and an image data file in which the unique ID is added to the identification information is created (S707). By performing such processing, data reproduction / reproduction can be performed even on an image data file photographed by a digital camera that cannot assign a unique ID to the image data file as in the related art shown in FIG. Since the management apparatus 601 can store the image data file to which the unique ID is added as the identification information, the inconvenience of inadvertently overwriting the same image data file can be solved.
[0066]
On the other hand, if the unique ID is included in the image data file, the hard disk drive 607 of the copy destination is searched, and one recorded image data file is read (S706), and the image data file as the copy source is read. (S708). Here, if the identification information of the copy source and copy destination image data files is the same, it is determined that they are the same image data file, and the copy process is skipped (S710).
[0067]
On the other hand, when it is determined that the identification information of the copy source image data and the copy destination image data file are not the same and are different image data files, all image data files recorded on the hard disk drive 607 are processed in the same manner as described above. Is performed.
[0068]
When there is no more image data file to be searched in the hard disk drive 607, the image data file to be copied is copied to the hard disk drive 607 (S711).
[0069]
When one image data file is copied in this way, it is determined whether or not an image data file to be copied remains on the memory card 101 (S712), and the image data file to be copied remains. If there is, the next image data file is read (S703), and the same processing as described above is repeated until there is no more image data file to be copied to the memory card 101.
[0070]
In the process shown in FIG. 7, in step 710 (S710), if the same image data file as the copy source exists in the hard disk drive 607, the copy process is skipped. However, the copy process is not skipped. Then, the image data file may be saved by overwriting the image data file or changing the file name.
[0071]
The processing in this case will be described with reference to the flowchart shown in FIG. FIG. 8 is a flowchart showing an operation procedure when an image data file is copied from a memory card to a hard disk drive.
[0072]
The processing shown in FIG. 8 is different from the processing shown in FIG. 7 in the processing when an image data file having the same identification information exists in the copy source and the copy destination, and the other processing is the same. .
[0073]
That is, in the processing shown in FIG. 8, the processing of steps 801 (S801) to 807 (S807) is the same as the processing of steps 701 (S701) to 807 (S807) shown in FIG.
[0074]
In the processing shown in FIG. 8, the image data file read from the memory card 101 is compared with the identification information of the image data file read from the hard disk drive 607 (S808), and the identification information of the copy source and copy destination image data files is determined. If they are the same, use a monitor or the like to indicate to the user that the same image data file exists, and overwrite the image data file, change the file name and save, or perform a copy process. Is selected (S810).
[0075]
Then, when the image data file is overwritten or the file name is changed and saved, the image data file to be copied is copied to the hard disk drive 607 with the same file name or a different file name. (S811). On the other hand, if the image data is not overwritten or the file name is not changed, the copy processing is skipped.
[0076]
Thereafter, the processing of step 809 (S809), step S811 (S811), and step 812 (S812) is performed in the same manner as in step 709 (S709), step S711 (S711), and step 712 (S712) shown in FIG. .
[0077]
Further, in the processing shown in FIG. 7, in step 702 (S702), the user is caused to determine whether or not to execute the copy. However, the copy may be automatically executed without the intervention of the user. Good.
[0078]
The processing in this case will be described with reference to the flowchart shown in FIG. FIG. 9 is a flowchart showing an operation procedure when copying an image data file from a memory card to a hard disk drive.
[0079]
The processing shown in FIG. 9 is different from the processing shown in FIG. 7 in that the processing for allowing the user to determine whether or not to execute copying is omitted, and the other processing is the same.
[0080]
That is, in the process shown in FIG. 9, when the PC card 609 is inserted into the PC card slot 606, the control unit 602 allows the image to be transferred from the rewritable area 101B of the memory card 101 without any user's judgment. The data file is read (S902).
[0081]
Thereafter, similarly to steps 704 (S704) to S712 (S712) shown in FIG. 7, the processes of steps 903 (S903) to S911 (S911) are performed.
[0082]
Further, in the processing shown in FIGS. 7 to 9, all the image data files recorded on the hard disk drive 607 are searched. Or only image data files having a specific extension may be searched.
[0083]
As described above, in the present embodiment, duplication and overwriting at the time of copying are controlled with reference to the identification information given to each image data file. Therefore, unlike the related art shown in FIG. 11, when the file names of the image data files recorded in the directory A and the directory B are duplicated, there is no inconvenience that uniqueness can be maintained only in directory units. Therefore, the uniqueness of the image data file can always be maintained.
[0084]
【The invention's effect】
As described above, according to the apparatus for copying a data file between recording media according to the present invention, when a data file is copied from a source recording medium to a destination recording medium, the data file is already recorded on the destination recording medium. Since the same data file is not redundantly recorded, the copying time is shortened, the recording area of the recording medium at the transfer destination can be effectively used, and furthermore, it is necessary to reverse the user's intention. The inconvenience of overwriting a new data file can be solved.
[0085]
Further, since the same data file can be easily detected, the user does not need to perform a data preview or the like to search for a desired data file as in the related art, thereby saving the trouble of copying the data file. be able to.
