Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a data processing technique, and more specifically, to a data processing technique capable of easily organizing files recorded on a plurality of recording media.
[0002]
[Prior art]
2. Description of the Related Art In recent years, with the development and spread of computer technology, digitization of information has been rapidly progressing. In particular, text data has been mainly used in the past, but various data such as still images and moving images have been digitized and handled with the improvement of the processing capability of the apparatus.
[0003]
These digital data usually have a low cost per storage capacity and are often recorded on magnetic or optical recording media capable of large-capacity storage. However, due to the lower cost and higher capacity of semiconductor memory. In particular, in a device such as a digital camera or a personal digital assistant (PDA) that requires miniaturization and durability, a detachable semiconductor memory such as a memory card is often used as a recording medium.
[0004]
Also, in computer equipment such as personal computers, removable recording media such as memory cards and card-type disk drive devices have been widely used as means for data exchange and data transfer.
[0005]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 2001-111928
[Problems to be solved by the invention]
Although such a removable recording medium is very convenient, there is a problem that as the number of recording media increases, the organization thereof becomes complicated.
[0007]
For example, in the case of a digital camera, the recording medium is equivalent to the film in a silver halide camera, and when the capacity is full, a new image must be taken unless the taken image is deleted and free space is secured. Can not. In recent years, the number of imaging elements is very large, the capacity per still image is large, and many apparatuses have a moving image shooting function. Therefore, the capacity of a memory card tends to be insufficient. Therefore, generally, a plurality of recording media are used while being exchanged.
[0008]
Further, since the same recording medium can be used in a digital camera or a computer device, there can be very many types of files in the recording medium.
[0009]
As a technique for facilitating the organization of files stored in a removable recording medium, for example, Japanese Patent Application Laid-Open No. H11-163873 discloses a technique of sorting an image file stored in a memory card in date order and outputting an index print. An image data processing device capable of assisting in organizing image files inside is disclosed.
[0010]
However, the technique described in Patent Literature 1 is directed to files stored in the same recording medium. Therefore, when files to be organized are recorded on a plurality of recording media, it is necessary for the user to check the files recorded on each recording medium, and to combine the files to be organized on one recording medium, which is troublesome and time consuming. Such a problem arises.
[0011]
SUMMARY OF THE INVENTION The present invention has been made in view of such problems of the related art, and has as its object to provide a data processing device capable of easily organizing files stored in a plurality of recording media.
[0012]
[Means for Solving the Problems]
That is, the gist of the present invention is that, for each of a plurality of recording media, information acquisition means for acquiring a maximum recording capacity and information about recorded files, and recording on a plurality of recording media based on information about files. Rearranging means for determining the recording order of files being recorded, determining means for determining a file to be recorded on each recording medium based on the recording order and the maximum recording capacity of each recording medium, Recording means for recording a file based on the determination by the determining means.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail based on preferred embodiments with reference to the accompanying drawings.
■ (First embodiment)
FIG. 1 is a block diagram illustrating a configuration example of a data processing device according to the first embodiment of the present invention.
[0014]
In FIG. 1, reference numeral 1 denotes a storage device (storage) for holding data such as an image file, which is a large-capacity storage device such as a hard disk drive. 2 is a sort processing unit that determines the order in which files are sorted, 3 is a data detection and reproduction unit that reads data from a recording medium set in the slot 4, and 4 is a unit that can set a plurality of recording media 8 to 12. A slot 5 is an operation key serving as an interface with a user. A CPU 6 controls each unit of the data processing device by executing a program stored in the storage 1 or a ROM (not shown). A slot 7 is set in the slot 4. A data recording unit 13 for recording data on the recording media 8 to 12 is a display unit including a display device such as an LCD. The above-mentioned items 1 to 7 and 13 constitute a data processing device. Reference numerals 8, 9, 10, 11, and 12 are randomly accessible recording media such as memory cards and magnetic / optical disks.
[0015]
The operation keys 5 can be configured not only with simple keys and buttons, but also with one or more commonly used input devices such as a pointing device such as a mouse and a touch panel.
[0016]
The recording media 8 to 12 may be physically different recording media, or may be logically partitioned volumes such as partitions in a hard disk drive.
[0017]
FIG. 2 is a diagram schematically illustrating data processing in the data processing device according to the present embodiment.
FIG. 2A shows a state in which recording media 8 to 12 each having a maximum recording capacity of 500 MB are set in the slot 4 of the data processing device. In this state, FILE0001. MPG, FILE0002. MPG, FILE0003. An MPG file is recorded. Similarly,
The recording medium 9 includes FILE0004. MPG, FILE0005. MPG, FILE0006. JPG,
The recording medium 10 includes FILE0007. MPG,
The recording medium 11 includes FILE0008. JPG, FILE0009. JPG,
The recording medium 12 has FILE0010. JPG, FILE0011. MPG, FILE0012. JPG,
Are recorded respectively.
[0018]
FIG. 2A also shows a recording date as an example of a time attribute of each file recorded on the recording media 8 to 12.
As will be described later, the data processing device according to the present embodiment sorts the files stored in the recording medium set in the slot 4 by date, and records the files again based on the sorted result.
[0019]
FIG. 2 (2) shows a state in which this processing has been completed.
The recording medium 8 includes FILE0007. MPG, FILE0008. JPG, FILE0010. JPG,
The recording medium 9 has FILE0001. MPG, FILE0009. JPG, FILE0002. MPG, FILE0003. MPG,
The recording medium 10 includes FILE0011. MPG, FILE0012. JPG, FILE0006. JPG,
The recording medium 11 includes FILE0004. MPG, FILE0005. MPG,
No file on the recording medium 12,
It becomes.
[0020]
Further, the data processing apparatus can display an image representing the state of the file rearrangement words on the display screen 13 as shown in (2) of FIG. Can be easily grasped.
[0021]
Next, the file reordering process of the data processing device according to the present embodiment will be described with reference to the flowchart shown in FIG.
In the following description, it is assumed that N (N is a natural number of 1 or more) recording media are set in slot 4 of the data processing device.
[0022]
First, 1 is substituted for a variable n as a counter (S301). Next, the data detection / reproduction block 3 acquires the maximum recording capacity (S302) and the file names, recording dates, and file sizes of all recorded files for the n-th recording medium set in the slot 4. (S303).
[0023]
One is added to n (S304), and it is determined whether n> N is satisfied (S305). If NO, the process returns to S302, and the processes of S302 to S303 are repeated for all the recording media. On the other hand, if YES in S305, it means that the file names, recording dates, and file sizes of all the files recorded on the N recording media have been obtained.
[0024]
The sort processing unit 2 determines the arrangement order of all files based on the acquired recording date (S306). Then, based on the arrangement order determined in S306 and the maximum recording capacity of each of the N recording media acquired in S302, a file to be recorded on each recording medium is determined, and a rearrangement list is determined (S307).
[0025]
It is determined whether sorting by the sorting list determined in S307 is possible (S308). If NO, the process ends without executing the rearrangement. In S308, for example, when the files are recorded in the order of the rearrangement list, N files are recorded in the order determined according to the relationship between the file size of the file to be subsequently recorded and the maximum recording capacity of each recording medium. It is determined, for example, that data cannot be written on the recording medium.
[0026]
If YES in S308, the data recording unit 7 records the file according to the rearrangement list, and ends the processing (S309).
[0027]
The method of the rearrangement process in S307 is arbitrary, but can be realized by, for example, the following method. First, all files stored in the recording media 8 to 12 are read out by the data detection / reproduction unit 3 and are once written in the storage 1. Then, the data is newly written to each of the recording media 8 to 12 by the data recording unit 7 in the order of the rearrangement list determined by the sorting processing unit 2. At this time, it goes without saying that the file originally recorded is erased and then written.
[0028]
Instead of reading all the files to the storage 1, only the disks that need to be moved as a result of sorting may be read to the storage.
[0029]
In S307 to S308 in FIG. 3, whether or not rearrangement is possible is determined based on the maximum recording capacity of each recording medium and the order determined in S306. When the maximum recording capacities are different, it may be performed for a plurality of types.
[0030]
That is, whether or not recording may be performed in an arbitrary order may be determined as well as when recording is performed in the order of the recording media 8, 9, 10, 11, and 12 (or vice versa). In other words, the determination may be made including the case where the physical positional relationship between the recording media 8 to 12 set in the slot 4 and the order of the recording media to which the files are written according to the rearrangement list do not match. .
[0031]
The user may set which of the recording media 8, 9, 10, 11, and 12 (or vice versa) to be recorded, and which of the recording media can be rearranged, to be prioritized, and switch according to the setting. .
[0032]
Furthermore, in the present embodiment, in S308, if the result of determining whether or not sorting by the sorting list determined in S307 is possible is NO, the process ends without executing sorting, but the user is allowed to edit the sorting order. Sorting may be performed. Further, the data processing apparatus according to the present invention may provide the user with another sort order in which the sort can be performed, and allow the user to select the sort order.
[0033]
According to the present embodiment, files recorded on a plurality of recording media and file data can be rearranged in chronological order and recorded again without causing the user to perform complicated editing work. It will be easier.
[0034]
■ (Second embodiment)
In the first embodiment, the sorting is performed based on the date of the file. However, the present embodiment is characterized in that the sorting is performed according to the type of the file.
[0035]
FIG. 4 is a diagram schematically illustrating a result of performing a file rearrangement process of the data processing apparatus according to the present embodiment on the file in the state of (1) in FIG.
In the present embodiment, the file type is distinguished by the extension of the file name (moving image “.MPG” and still image “.JPG”). However, any other attribute (type attribute) indicating the file type is used. The type of the file may be determined accordingly.
[0036]
The configuration of the data processing apparatus according to the present embodiment may be the same as that of the first embodiment, and the reordering process is the same as the reordering process performed in S306 in the procedure described with reference to FIG. Hereinafter, only the rearrangement process performed in S306 in the present embodiment will be described. In the case where classification is performed using an attribute other than the file name extension, it is needless to say that the attribute is acquired in S303.
[0037]
First, the files recorded on the recording media 8 to 12 are classified according to their types, and data processing for dividing the recording media to be recorded is performed. In FIG. 4, first, the files of FILE0001 to FILE0012 are divided into moving image and still image files. MPG, FILE0002. MPG, FILE0003. MPG, FILE0004. MPG, FILE0005. MPG, FILE0007. MPG, FILE0011. MPG.
The still image file is FILE0006. JPG, FILE0008. JPG, FILE0009. JPG, FILE0010. JPG, FILE0012. JPG.
[0038]
Next, a recording medium for recording a still image file having a small file size is determined. As described above, since all of the recording media 8 to 12 have a maximum recording capacity of 500 MB, a still image file can be collectively recorded on any one recording medium. Here, when all the still image files are recorded on the recording medium 12, and the moving image files are rearranged in the rearrangement list divided by the maximum recording capacity of the remaining recording mediums 8, 9, 10, and 11, FIG. As shown in
The recording medium 8 has FILE0001. MPG, FILE0002. MPG, FILE0003. MPG,
The recording medium 9 includes FILE0004. MPG, FILE0005. MPG,
The recording medium 10 includes FILE0007. MPG,
The recording medium 11 includes FILE0011. MPG,
The recording medium 12 includes FILE0006. JPG, FILE0008. JPG, FILE0009. JPG, FILE0010. JPG, FILE0012. JPG
The sorting list for performing the recording is determined.
[0039]
Also, after sorting by file type, sorting is performed based on date information as in the first embodiment, or sorting is further performed by other additional information such as GPS information and file names. A replacement list may be determined.
Alternatively, a rearrangement list may be determined such that the number of recording media having no recording file increases (a large recording area can be obtained).
[0040]
According to the present embodiment, as in the first embodiment, files recorded on a plurality of recording media can be rearranged for each file type and recorded again without causing the user to perform complicated editing work. Because of this, files can be easily organized. Also, rearrangement can be performed under other conditions such as a combination with the first embodiment.
[0041]
■ (Third embodiment)
In the first and second embodiments, files recorded on a plurality of recording media have unique file names. However, it is possible that files having the same name exist on different recording media. In some cases, a situation may occur in which files to be written to the same recording medium include a plurality of files having the same name. The present embodiment takes such a case into consideration.
[0042]
In the following, the case where the rearrangement processing in the present embodiment is performed on the recording date of the file as in the first embodiment will be described as an example. However, the classification according to the type described in the second embodiment, It is needless to say that the present invention can be applied to a sorting process based on a combination.
[0043]
FIG. 5A shows a state of a file recorded on each of the recording media 8 to 12 before the rearrangement process.
The data processing device according to the present embodiment also has the configuration shown in FIG. It is also assumed that each of the recording media 8 to 12 set in the slot 4 has a maximum recording capacity of 500 MB.
[0044]
In the state of FIG.
The recording medium 8 has FILE0001. MPG, FILE0002. MPG, FILE0003. MPG,
The recording medium 9 includes FILE0004. MPG, FILE0005. MPG, FILE0006. JPG,
The recording medium 10 has FILE0001. MPG,
The recording medium 11 includes FILE0008. JPG, FILE0006. JPG,
The recording medium 12 has FILE0010. JPG, FILE0011. MPG, FILE0006. JPG,
Is recorded on the recording medium 8 and the recording medium 10 with the file name FILE0001. Files with different contents of the JPG are recorded. The recording medium 9, the recording medium 11, and the recording medium 12 have the file name FILE0006. Files with different contents of the JPG are recorded.
[0045]
Next, a rearrangement process according to the present embodiment will be described. Also in this embodiment, the basic processing flow is the same as the flowchart in FIG. 3 described in the first embodiment, and only the contents of the arrangement order determination processing and the recording destination medium determination processing in S306 and S307 are different. Therefore, in the following description, only the processing unique to the present embodiment will be described.
[0046]
First, as described in the first embodiment, the arrangement order is determined in chronological order based on the recording date of each file, and then each file is recorded at the maximum recording capacity of each recording medium. The recording medium is determined, and the sorting list is determined. The relationship between this list and the storage medium of the write destination is shown in (2) of FIG.
[0047]
Here, looking at the file names of the files recorded on each storage medium, the file names FILE0001. The two files of JPG are recorded on different recording media, so there is no problem. However, the file names FILE0006. It can be seen that two of the three files of the JPG are included in the files to be recorded on the recording medium 10.
[0048]
In such a case, the sort processing unit 2 in the present embodiment changes the file names of (m-1) files among m files (m ≧ 2) of the same name to be recorded on the same recording medium. I do. How to select a file whose file name is to be changed can be arbitrarily determined. In the present embodiment, for example, FILE0006. Change the JPG file name. That is, in FIG. 5, FILE0006. JPG, RFIL0006. JPG.
[0049]
FIG. 5C shows a rearrangement list after such a file name change process is performed. In this way, after the file names are not duplicated in the same recording medium, writing is performed according to the processing results of S308 and S309.
[0050]
When the file name is changed, the data processing device can notify the user of the change in the file name by displaying a message on the display unit 13 or the like.
[0051]
In the present embodiment, when it is desired to record a plurality of files having the same file name on one recording medium, the data processing apparatus changes the file name without making the user aware, but warns the user that the same file name exists. Alternatively, the user may select a file name to be renamed.
[0052]
In the present embodiment, when it is desired to record a plurality of files having the same file name on one recording medium, data processing for recording on a recording medium without the same file name without changing the file name may be performed. For example, in the case of FIG. 5B, FILE0006. What is necessary is just to record from JPG to the recording medium 11.
[0053]
In the present embodiment, the file name is changed only when it is desired to record a plurality of files having the same file name on one recording medium. However, regardless of whether the recording destination recording medium is the same, the file name is changed so that the file name is not duplicated. You may change your name.
[0054]
According to the third embodiment of the present invention, when the data processing of the present invention is executed and it is desired to record a plurality of files having the same file name on one recording medium, the recording on the recording medium can be performed by changing the file name. Will be possible. Also, by notifying the user of the change in the file name, the user can confirm that the file name has been changed.
Note that the third embodiment can be implemented in combination with the first and second embodiments.
