DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file storage device, and more particularly, to display, correction, rewriting, and printing of an image file which is connected to devices such as a television, a printer, and a personal computer and stored therein. And a file storage device capable of performing various processes such as the above.

[0002]

2. Description of the Related Art In recent years, with the rapid spread of digital cameras, various demands have been made for processing digital images. As one of them, there is a demand that even a person who does not have a personal computer can print a digital image taken by a digital camera and perform various image processing.

For this reason, a file storage device that can reproduce an image in a stand-alone manner as long as it is connected to a monitor screen of a TV or the like has been proposed.

[0004] The file storage device is a floppy (registered trademark) disk (FD), a PC card, an MO, a HiF.
D (trade name; manufactured by Fuji Photo Film Co., Ltd.), an image read from a recording medium such as a magneto-optical disk or a smart media is displayed on a monitor screen such as a TV to perform image processing, or is displayed on a monitor screen such as a TV. The displayed image is output to a connected printer and printed out, and various processes can be performed without using a personal computer.

[0005] Of course, there is also a file storage device which is connected to a personal computer via an interface such as SCSI or USB to output a file stored in the file storage device to the personal computer or to store an image input from the personal computer. Proposed.

In recent years, there has been an increasing demand for compatibility of image files photographed by a digital camera, and one file structure is constructed by a plurality of types of files such as a main image file, a display file, a thumbnail file, and an audio file. DCF (Design rule for Camera
File system) is standardized, and a digital camera compatible with the DCF standard has been proposed.

[0007]

In a file storage device employing a file system in which one file configuration is constructed by a plurality of types of files, the file configuration is not configured such as an image file installed from a personal computer or the like. When storing a single image file, it is necessary to newly create a plurality of types of files in a predetermined combination for constructing a file configuration together with storing the image file.

For example, based on the input main image file, a plurality of types of files such as a display image file for displaying a television screen, a thumbnail image file for displaying a reduced image, and an image file for printing are provided. Need to be created.

Of course, it is possible to store only the main image file without creating a plurality of these files. For example, when displaying the main image file on a screen such as a television or a CRT, the main image file is converted into an image file for screen display. Must be created, which makes the work complicated and gives the user trouble.

[0010] In addition, the work of creating a plurality of types of files of a predetermined combination for constructing a file structure requires, for example, the number of types for constructing the file structure for one image file, and thus a huge amount of work is required. Storing a large amount of image files in the file storage device requires a huge amount of work, which places a burden on the user.

Further, when one or more files among a plurality of files constituting the file structure are deleted or rewritten, the file structure is destroyed, so that an image cannot be displayed, sound cannot be output, or in the worst case, In this case, the file structure may be destroyed, and all files related to the file structure may not be used.

In particular, when a plurality of types of files for constructing a file configuration are separately stored in directories created for each type of file, it is difficult to recognize the relationship between the plurality of types of files. There is a great possibility that the file structure is destroyed due to accidental deletion of the file to be created, which is a problem.

Further, even if the file structure is destroyed and the file becomes unusable, the other files remain stored in the file storage device and are not deleted unless the user selects and deletes them. . Therefore, unnecessary data that cannot be grasped by the user accumulates in the file device, and there is a problem that memory capacity is unnecessarily consumed.

In view of the above, the present invention provides a file storage system employing a file system that stores a plurality of types of files of a predetermined combination that constitute one file configuration in directories created for each type of file. In the device, delete, rewrite,
An object of the present invention is to provide a file storage device in which management of a file configuration such as creation and maintenance is easy.

[0015]

According to a first aspect of the present invention, there is provided a file storage device which stores a plurality of files of a predetermined combination for constructing one file configuration, for each file type. And a file configuration maintenance unit for deleting all files belonging to the same file configuration as the predetermined file when deleting a predetermined file from the plurality of types of files. ing.

In the file storage device according to the present invention, the file structure maintaining means deletes all files belonging to the same file structure as the file when deleting a predetermined file from a plurality of types of files constituting one file structure. Therefore, it is possible to delete files related to the file to be deleted at once.

Therefore, destruction of the file configuration due to inadvertent deletion can be prevented. Further, since the entire file structure to which the file belongs can be deleted simply by deleting one file, the erasing operation is easy.

Further, since the file configuration maintenance means performs the deletion process for each file configuration, there is no fear that another file belonging to the file configuration of the file to be deleted is not deleted. Therefore, it is possible to prevent unnecessary data that is not grasped by the user from accumulating in the storage means due to forgetting to delete unnecessary files, and to effectively use the memory capacity.

Further, depending on the type of device connected to the file storage device, unnecessary or unusable types of files may be included in the file configuration. From this,
According to the present invention, when a file of a predetermined type is selected as a predetermined file from among a plurality of types of files of a predetermined combination forming one file configuration, and a file of a predetermined type is selected and deleted, In addition to deleting all files belonging to the file structure of the file, when a file other than a predetermined type of file is selected and deleted, only the selected file is deleted and other files are left. it can.

Thus, the deletion process can be selected according to the type of the file. If there is an unnecessary file among the files other than the predetermined type of file, the unnecessary file is deleted while the unnecessary file is deleted. When files of a predetermined type are deleted, all the files belonging to the file configuration are deleted, so that the storage capacity can be effectively used by selectively deleting.

Further, in the invention according to claim 2, the file configuration maintenance means, when rewriting the predetermined file,
After the predetermined file and all files belonging to the same file configuration as the predetermined file are deleted, a new file and a file belonging to the same file configuration as the new file may be stored in the storage unit.

According to the present invention, the file configuration maintenance means includes:
Since the rewriting process is performed for each file configuration, there is no fear of forgetting to delete or failing to rewrite other files belonging to the same file configuration as the predetermined file to be rewritten.

Accordingly, when the predetermined file is rewritten, both the predetermined file and other types of files belonging to the same file configuration as the predetermined file are deleted from the storage means, so that the files which the user does not recognize are stored in the storage means. It can be prevented from being left, and the memory capacity can be used effectively.

Also, by one rewrite instruction signal,
Since all files belonging to the file configuration to be rewritten can be rewritten, the rewriting operation by the user can be simplified, and a file storage device with improved operability can be obtained.

Further, according to the third aspect of the invention, in the file storage device according to the first or second aspect,
The file configuration maintenance unit is configured to reject the instruction when either one of the delete instruction and the rewrite instruction is issued, and to execute the rejection mode when one of the delete instruction and the rewrite instruction is issued. A receiving mode for receiving the instruction; and a selecting means for selecting one of the rejecting mode and the receiving mode.

In the reject mode, when either a delete instruction or a rewrite instruction is issued to a file belonging to the file configuration, the change is rejected to change the file stored as the file configuration. I try not to do it easily. The selecting means selects one of the accepting mode and the rejecting mode, and determines whether the change processing is enabled or disabled for the file configuration.

When the selecting means selects the reject mode,
Since the deletion or rewriting of the file is refused and the change processing of the file configuration becomes impossible, the destruction of the file configuration due to the deletion or rewriting of the file can be prevented.

Further, when the selection means selects the reception mode, it is easy to manage the file configuration such as deletion and rewriting of the file configuration as described above, and it is possible to effectively use the memory capacity.

According to a fourth aspect of the present invention, there is provided a file storage device for storing a plurality of types of files of a predetermined combination belonging to one file configuration in directories created for each type of files. When,
A file configuration maintenance unit that rejects the instruction when either the deletion instruction or the rewriting instruction is issued to the file.

That is, according to the present invention, when either one of the delete instruction and the rewrite instruction is issued to the file for constructing the file configuration by the file configuration maintenance means, the instruction is rejected. Can not be easily changed, and it is possible to prevent the file configuration from being destroyed and the file configuration from being destroyed due to the deletion or rewriting of the file.

[0031] The invention of claim 5 is the invention of claims 1 to 4.
5. The file storage device according to claim 1, wherein, when a single file is input, the file configuration maintenance unit creates the plurality of types of files based on the single file, and Is stored.

According to a sixth aspect of the present invention, there is provided a storage means for storing a plurality of types of files in a predetermined combination for constructing one file configuration in directories created for each type of file, respectively, And a file configuration maintenance unit that creates the plurality of types of files based on the single file and stores the files as one file configuration in the storage unit.

In the file storage device according to the fifth and sixth aspects of the present invention, when a single file having no file configuration is input, the file configuration maintenance means can execute a plurality of types of files from the input file. Create 1
Since the file structure is stored as one file structure, when storing a single file whose file structure is not constructed, it is not necessary for the user to create another type of file for constructing the file structure to cause the file structure to be constructed.

For this reason, simply storing a single file having no file structure is stored, and other types of files that constitute a file structure for the single file are also stored, so that the file structure can be easily managed. Also,
Immediately after a single file having no file configuration is stored in the file storage device, it can be used by another device connected to the file storage device, and operability is improved.

In particular, when the single file is an image file, the file configuration maintenance means may generate a display image file and a reduced display image file based on the image file. It can be configured to create two or more types of files, including:

When storing an image file, the file storage device may be connected to image display means such as a TV, a CRT, or a liquid crystal display in order to display an image represented by the image file. Therefore, if the single file is an image file, the file is saved by creating a file in advance so as to include at least one of the display image file and the reduced display image file among the files constituting the file structure. Immediately after the image file is stored in the device, the image file can be displayed on the image display means connected to the file storage device, thereby improving operability.

Various programs such as a control program necessary for controlling the file device are stored. The rewrite selection program will be described later. The RAM 30 stores various data and control signals required for each of the programs input via the bus 40.

The main memory 20 is controlled based on a DCF file input from an external device such as the personal computer 50 or the printer 54 via the I / F 24 or an image file input from an external device such as the personal computer 50 or the printer 54. The DCF file (details will be described later) created by the unit 18 is stored.

The memory card drive 22 includes the controller 1
And writes data such as DCF files, image data, and compressed image data stored in the memory card 32 based on a read signal from the control unit 18 to write the data to the main memory. It is stored in the memory 20. Here,
Smart media, floppy disk (FD), M
A large-capacity recording medium such as O and HiFD, and various recording media such as a magneto-optical disk are collectively referred to as a memory card 32. Therefore, the memory card drive 22 is provided corresponding to the type of recording medium that the file device 10 can read and write.

Here, a control routine performed by the CPU 26 based on the rewrite selection program read from the ROM 28 will be described with reference to the flowchart of FIG.

In the present embodiment, as an example, a main image file (DSCFxxxx.JP) as shown in FIG.
G; where x is an arbitrary positive integer, xxxx is an object name, and a display file (DSPxxxx.JP
G), thumbnail file (THUMxxxx.JP)
G), a DCF file (xxxx is composed of a group of objects having the same numerical value, wherein one file configuration is constructed by a plurality of different types of DCF objects such as an audio file (MUSCxxx.WAV) and a text file (TXTxxx.TXT). ) Is applied to the file device 10. Note that FIG. 4 illustrates a case where the DCF object is constructed from three types of a main image file, a display file, and a thumbnail file for the sake of simplicity.

When a file is selected in step 100 of FIG. 3, it is determined in step 102 whether a delete instruction signal has been input for the selected file. If a delete instruction signal has been input, step 104 is performed. Then, if no delete instruction signal is input, the flow shifts to step 112.

At step 104, the mode selection button 1
In step 4, it is determined whether the rewrite / delete prohibition mode is selected. When the rewrite / delete prohibition mode is selected, the rewrite / delete is prohibited, so that the delete instruction signal is rejected, and this routine ends. At this time, it may be configured to warn that the selected file has the read-only attribute and cannot be deleted.

If the rewrite / delete prohibition mode is not selected in step 104, the rewrite / delete permitted mode is selected, and the mode can be deleted.

In step 106, it is determined whether or not the designated file is a main image file (DSCFxxxx.JPG; x is an arbitrary number). If it is a main image file, the process proceeds to step 108, where the main image file (DSCFxx
xx. JPG) and the display file (DS) belonging to the same file structure as the main image file.
Pxxxx. JPG; xxxx is the same numerical value as the main image file), thumbnail file (THUMxxxx.JP)
G; xxxx is the same numerical value as the main image file), and all files such as the audio file (MUSCxxxx.WAV) and the text file (TXTxxx.TXT) are deleted, and the routine ends. For example, in FIG. When a deletion instruction signal is input to JPG, DSP0002. JPG, THUM00
02. All files in which JPG and other 0002 are described in the name will be deleted.

If it is determined in step 106 that the specified file is not the main image file, only the specified file is deleted and the routine ends. For example,
In FIG. 4, THUM0003. When a delete instruction signal is input to the JPG, THUM0003. JPG is deleted and DSCF0003. JPG, DSP00
03. All files that have JPG and other 0003 in their names will be left. Note that the display file and the thumbnail file can be created again from the main image file, and are generated from the main image file when necessary.

On the other hand, if it is determined in step 102 that a deletion instruction signal has not been input to the selected file, the process proceeds to step 112, where a rewrite instruction signal is input to the selected file. If the file has not been input, it means that the file has been selected for another processing, and this routine ends.

If a rewrite instruction signal is input in step 102, the process proceeds to step 114, and it is determined whether the mode selection button 14 has selected the rewrite / delete prohibition mode. When the rewrite / delete prohibition mode is selected, rewrite is prohibited, and the rewrite instruction signal is rejected, and this routine ends. At this time,
It may be configured to warn that the selected file has the read-only attribute and cannot be rewritten.

If the rewrite / delete prohibition mode is not selected in step 114, rewrite is possible since the rewrite / delete permitted mode has been selected, and the process proceeds to step 116.

In step 116, it is determined whether the selected file is an image file, that is, one of a main image file, a display file, and a thumbnail file. If the selected file is not an image file, it is a file that is not related to an image such as an audio file, so the process proceeds to step 122, where only the selected file is deleted. End the routine.

If the selected file is an image file, that is, if it is one of the main image file, the display file, and the thumbnail file, the process goes to step 118 to delete the selected file. At the same time, after deleting all files belonging to the object of the selected file, in the next step 120, a main image file to be newly written, and all types of files constructing a file structure such as a display file and a thumbnail file Is written, and this routine ends.

For example, in FIG.
3. When a rewrite instruction signal is input to the JPG, DSCF0003. JPG, DSP0003. JP
G and THUM0003. After deleting the JPG, the directory is changed to 101_FUJI and a new DSCF00 is created.
03. JPG, DSP0003. JPG and THUM0
003. Write JPG. DSP0003. J
Similarly, when a rewrite instruction signal is input to DSCF0003. JPG, DSP0003. JP
G and THUM0003. After deleting the JPG, the directory is changed to 101_FUJI and a new DSCF00 is created.
03. JPG, DSP0003. JPG and THUM0
003. Write JPG.

As described above, since the file is rewritten in units of objects by the rewrite selection program, it is possible to prevent the file structure of the object from being broken due to careless file rewriting by the user. Therefore, for example, it is possible to avoid various problems caused by the destruction of the file structure, such as the file structure being destroyed and the file being unusable.

Since other than the main image file can be re-created later when necessary, it is possible to avoid the problem that unnecessary files are stored and the memory capacity is wasted. it can.

Further, when a file is deleted, unnecessary data that cannot be grasped by the user can be prevented from accumulating in the file device since the file is deleted in units of objects, and the memory capacity is wasted from this point. Problem can also be avoided.

In addition, at the time of new recording and rewriting of image data, a file configuration is created by the rewriting selection program and recorded as an object, so that there is no need for the user to create an object, and the object can be deleted, rewritten, created, and deleted. Object management such as maintenance is easy.

In the file device according to the present embodiment described above, the configuration in which the mode select button 14 can be used to switch between the two modes of the rewritable / deletable mode and the rewritable / deleted prohibition mode has been described.
It is also possible to prohibit file rewriting / deletion for all files stored in 0 and maintain the file configuration.

In this case, an object configuration maintenance program is stored in the ROM 28 instead of the rewrite selection program, and the control unit 18 reads the object configuration maintenance program from the ROM 28 and performs control based on the object configuration maintenance program.

This control routine will be described with reference to the flowchart of FIG. First, when a file is selected in step 200, it is determined in step 202 whether a deletion instruction signal has been input for the selected file. If the deletion instruction signal is input, step 20
4 and reject the deletion instruction signal, and
Move to In step 206, a sound or text warns that the selected file has the read-only attribute and cannot be deleted, and ends this routine.

On the other hand, if it is determined in step 202 that a deletion instruction signal has not been input to the selected file, the process proceeds to step 208, where a rewrite instruction signal is input to the selected file. If the file has not been input, it means that the file has been selected for another processing, and this routine ends.

If a rewrite instruction signal is input in step 208, the process proceeds to step 210, rejects the rewrite instruction signal, and proceeds to step 212. In step 212, a warning is given by sound or text that the selected file has the read-only attribute and cannot be rewritten or deleted, and the routine ends.

As described above, since the deletion of the file is prohibited by the object configuration maintenance program, it is possible to prevent the file configuration of the object from being broken due to the careless deletion of the file by the user. Therefore, for example, it is possible to avoid various problems caused by the destruction of the file structure, such as the file structure being destroyed and the file being unusable.

Here, a control routine performed by the CPU 26 based on the storage control program read from the ROM 28 will be described with reference to the flowchart of FIG.

First, in step 300, it is determined whether a file storage instruction signal has been input. If it is determined in step 300 that the file storage instruction signal has been input, the process proceeds to step 302 to determine whether the input file is a DCF file. If it is determined in step 302 that the file is a DCF file, the process proceeds to step 304, where the file is stored in the main memory 20, and the routine ends.

On the other hand, if it is determined in step 302 that the input file is not a DCF file, the flow advances to step 306 to determine whether the input file is an image file.
If it is determined that the image file is not an image file, the process proceeds to step 304, where it is stored in the main memory 20, and this routine ends.

If it is determined in step 306 that the image file is an image file, the process proceeds to step 308, where a display image file and a thumbnail file are created based on the input image file. Main memory 20 with the image files
And the routine ends.

In this embodiment, if the input file is a DCF file, the file is stored as it is. If the input file is an image file, a display image file and a thumbnail file are created and stored as a DCF file. Since the storage method is changed according to the type of the input file, such as storing the image file as it is, it can be displayed on the TV screen immediately after the image file is stored, the thumbnail can be displayed on the personal computer, the memory card 32 and can be reproduced by a digital camera.

In this embodiment, a case where a personal computer and a television are connected as display devices has been described. However, the present invention is not limited to this configuration. For example, a liquid crystal display of a digital camera can be directly connected to a digital camera. The screen can be used as a display device.
