Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a data file management device that performs file management using a directory structure when a data file obtained by an imaging device, a measurement device, or the like is recorded on a recording medium.
[0002]
[Prior art]
In a conventional digital still camera (hereinafter referred to as DSC), a number included in a file name is incremented every time it is shot, so that the shot data file is saved or copied or moved to a PC. In addition, duplicate file names are prevented.
[0003]
Japanese Patent Application Laid-Open No. 11-110531 discloses a method for determining a file name based on a shooting date when collecting images that are generated independently by a plurality of independent image generators in one place and managing them collectively. There is a proposal in which the file name of each image is not duplicated.
[0004]
On the other hand, with the widespread use of DCS, there has been a growing demand to play back captured images on other DSCs. Therefore, DCF (Design rule) under the Japan Electronics Industry Promotion Association is intended to enable direct exchange of data files between DSCs. for Camera File system) was established. Recently, DCS-compliant DCS is increasing.
[0005]
[Problems to be solved by the invention]
However, in the above-described conventional DSC, each DSC determines a file name according to its own law as described in Japanese Patent Application Laid-Open No. 11-110531. There is a high possibility that it cannot be read by DSC.
[0006]
Therefore, although DCF has been established, only a file name of a character string that is meaningless to the user can be attached to a data file shot with a DCF-compliant camera.
[0007]
Therefore, when a general user copies this data file to a personal computer, it is often renamed to a significant file name. However, the data file is viewed for some reason (for example, returning to the DSC where it was shot, etc. When a request to return to the DSC again occurs in the DCS, etc.), the renamed data file cannot be read by the DSC.
[0008]
In addition, there is a possibility that a data file shot by one DSC has a format that cannot be read by another DSC.
[0009]
The present invention has been made in view of the above problems, and automatically renames a data file having a file name that cannot be read by the DSC to a file name that can be read by the DSC. Thus, a data file management apparatus that enables reading of a data file is provided.
[0010]

[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a first embodiment of the present invention will be described in detail with reference to FIGS. Here, FIG. 1 is a block diagram showing a schematic configuration in the data file management apparatus of the present embodiment, and FIGS. 2 to 4 are explanatory diagrams showing the directory structure of each recording medium in the data file management apparatus of the present embodiment.
[0018]
In FIG. 1, the rename unit 2 on the data file management device 1 copies or moves a data file on a large-capacity recording medium 5 such as a PC to another recording medium 6 such as a cable-connected memory or smart media. Rename (update) the file name.
[0019]
At this time, the character string generation unit 3 determines the character string part of the file name, and the number string generation unit 4 determines the number string part of the file name.
[0020]
Here, an example applied to a DSC that can reproduce only a data file having a file name represented by “(AAA) + (file number 5 digits)” will be described.
[0021]
As shown in FIG. 2, captured data files “AAA00001”, “AAA00002”, etc. are stored on another recording medium 6. These data files are assumed to have the extension “.JPG”, but are not shown for simplicity.
[0022]
Here, consider a case where the user moves the data file “AAA00003” on the recording medium 6 to the large-capacity recording medium 5 such as a PC for the reason of increasing the free capacity of the other recording medium 6.
[0023]
As shown in FIG. 3, the data file “AAA00003” is transferred to the large-capacity recording medium 5, but the user cannot guess the contents of the data file with this file name. It is stored in the large capacity recording medium 5 above.
[0024]
Then, consider a case where a reason such as viewing the data file back to the DSC or playing it on another DSC occurs. Here, it is assumed that the data file on the other recording medium 6 is as shown in FIG. 4 as a result of shooting and deletion after moving “AAA00003”.
[0025]
First, the numeric string generation unit 4 searches for a data file on another recording medium 6 and obtains the minimum value “00002” of the unused file numbers. On the other hand, the character string generation unit 3 searches the data file on the other recording medium 6 to obtain the character string “AAA” being used.
[0026]
Therefore, “flower” is renamed “AAA00002” and moved to another recording medium 6. Here, when the user wants to leave “flower” on the large-capacity recording medium 5, a copy of “flower” may be made, renamed to “AAA00002”, and moved.
[0027]
In addition, the number string generation unit 4 can be renamed “AAA00005” by using the number next to the maximum number of used numbers, not the minimum number of unused numbers.
[0028]
Next, as a second embodiment of the present invention, an example applied to a DCF-compliant DSC will be described with reference to FIGS. Here, FIG. 5 is a block diagram showing a schematic configuration in the data file management apparatus of the present embodiment, and FIGS. 6 to 10 are explanatory diagrams showing the directory structure of each recording medium in the data file management apparatus of the present embodiment.
[0029]
In FIG. 5, except for the renumbering unit 7, the same function as that shown in FIG. 1 is performed, and the renumbering unit 7 makes the file number continuous with the data file on the other recording medium 6. To be updated.
[0030]
Here, the DCF-compliant DSC is a DSC capable of reproducing only a data file having a file name as shown in FIG. That is, the DCF data file has a file name represented by “(4 free characters) + (file number 4 digits)”.
[0031]
Also, as shown in FIG. 7, the DCF data file must be placed under the directory “DCIM”. In addition, arbitrary half-width uppercase alphanumeric characters can be used for the free characters, and numbers “0001” to “9999” can be used for the file numbers.
[0032]
Here, as in the case of the description of the first embodiment, a case is considered in which a captured data file is moved to the large-capacity recording medium 5 and then returned to the DSC for reproduction.
[0033]
First, a captured data file is stored on another recording medium 6 with a file name such as “IMGN0001”, “IMGN0002”,... As shown in FIG. Here, “IMGN” and “IMGF” are free character strings automatically assigned by the DSC.
[0034]
Next, as shown in FIG. 8, the user moves the data file “IMGN0002” to the large-capacity recording medium 5 and renames it to a significant file name “flower”, for example, in order to easily guess the file contents.
[0035]
When returning this data file to the DSC, as shown in FIG. 9, first, the numeric string generation unit 4 searches for the data file on the other recording medium 6 and sets the minimum value “0002” of the unused file number. Ask.
[0036]
On the other hand, the character string generating unit 3 generates a character string portion using a preset character string. In this example, “COPY” is used so that it can be easily distinguished from the data file that originally exists on the other recording medium 6. Therefore, “flower” is renamed “COPY0002” and moved to another recording medium 6.
[0037]
Also, as shown in FIG. 10, the renumbering unit 7 updates the file number of the data file on the other recording medium 6 so that it continues from an arbitrary number, for example, “0001”, and is used thereafter. It is also possible to obtain the minimum value “0004” of the file number that does not exist. In this case, “flower” is renamed “COPY0004” and moved.
[0038]
Next, as a third embodiment of the present invention, an example applied to a plurality of DSCs that record data files in different formats will be described with reference to FIGS. Here, FIG. 11 is a block diagram showing a schematic configuration in the data file management apparatus of the present embodiment, and FIGS. 12 and 13 are explanatory diagrams showing the directory structure of each recording medium in the data file management apparatus of the present embodiment.
[0039]
In FIG. 11, except for the profile selection unit 8 and the format conversion unit 9, the same function as that shown in FIG. 1 is performed. The profile selection unit 8 allows the user to select the profile of the copy destination data file, The format converter 9 converts the data file into an appropriate format.
[0040]
Here, as in the case of the description of the first embodiment, a case is considered in which a captured data file is moved to the large-capacity recording medium 5 and then returned to the DSC for reproduction.
[0041]
As shown in FIG. 12, among the data files “AAAA0001”, “AAAA0002”... Existing on the other recording medium a10, “AAAA0002” is moved to the large-capacity recording medium 5, and the file name “flower” "".
[0042]
Here, consider a case where this data file is transferred to another DSC. In the example shown in FIG. 13, the data file is moved from the large-capacity recording medium 1 to another recording medium b11 in which data files such as “BBBB0001”, “BBBB0002”.
[0043]
It is assumed that the DSC having the other recording medium b11 cannot read the formats “AAAA0001”, “AAAA0002”,..., And can only read data files having file names that begin with “BBBB”.
[0044]
First, the user selects a destination DSC profile by the profile selection unit 8. Here, the profile is information of a data file that can be reproduced by DSC, and represents, for example, a data format, the number of pixels, a screen aspect ratio, a file name specification, and the like.
[0045]
The profile selection unit 8 notifies the format conversion unit 9 of a format that can be read by the destination DSC based on the selected profile, and the format conversion unit 9 converts the data format and the like based on the information.
[0046]
Furthermore, the profile selection unit 8 notifies the rename unit 2 of the file name rule, and the character string generation unit 3 generates the character string “BBBB” based on the information. Further, the number string generation unit 4 searches the other recording medium b11 to obtain the minimum value “0004” of the unused file numbers. Therefore, after “flower” is renamed to “BBBB0004”, it is possible to move to another recording medium b11.
[0047]
【The invention's effect】
According to the data file management apparatus of claim 1 of the present application, a data file having a file name that exists on the first recording medium and cannot be read by a reproducing apparatus having the second recording medium is automatically detected. In particular, a data file can be read by the playback device by renaming the file name to be readable by the playback device and then copying or moving the file name to the second recording medium.
[0048]
According to the data file management apparatus of claim 2 of the present application, the character string in the file name of the data file existing on the second recording medium is the character string portion in the file name of the data file to be copied or moved. When the free characters of the file name that can be read by the reproducing apparatus having the second recording medium are limited, the renaming can be automatically performed without receiving user input.
[0049]
According to the data file management device of the present invention, the preset character string is used as the character string portion in the file name of the data file to be copied or moved, so that the file name that can be read by the playback device If the rules are known, renaming can be done automatically without any user input.
[0050]
According to the data file management device of the present invention, the character string portion in the file name of the data file to be copied or moved is determined based on the information selected by the profile selection means. Even if the file name that can be read by is different, it can be read.
[0051]
According to the data file management device of the present invention, since the format conversion is performed simultaneously with the file name change based on the information selected by the profile selection means, the format can be read among a plurality of playback devices. Even when the file names are different, reading is possible.
[0052]
According to the data file management device of claim 6 of the present application, the minimum value of a number that is not used in the file name of the data file existing on the second recording medium is changed in the file name of the data file to be copied or moved. Since it is a numeric string part, it is possible to effectively use the numbers that can be used and prevent duplication of file names.
[0053]
According to the data file management device of claim 7 of the present application, after the number string portion in the file name of the data file existing on the second recording medium is updated so as to be continuous with an arbitrary number, the second recording Since the minimum value of the number that is not used in the file name of the data file that exists on the medium is obtained and used as the number string portion in the file name of the data file to be copied or moved, the number that can be used is used effectively and the file Numbers can be added in the data recording order.
