[0007]

In order to achieve the above object, the invention according to claim 1 provides a plurality of files, information indicating a correspondence relationship between a real folder hierarchy and a virtual folder hierarchy of the files, and a unique identification. A file display device for displaying a file on a non-rewritable recording medium in which a script file having information has been written, comprising storage means for storing the script file, reading means for reading information on the recording medium, and A discriminating means for discriminating whether or not a script file having the same identification information as the identification information of the script file recorded in the recording medium when the recording medium is attached to the reading means; If it is determined that the script is not stored, the script recorded on the recording medium is recorded. Displaying a virtual folder hierarchy based on a file, and displaying the virtual folder hierarchy based on a script file having the same identification information stored in the storage means when the determination means determines that the virtual folder hierarchy is stored. Means, folder operation means for enabling file operations within the displayed virtual folder hierarchy, and when file operation is performed by the folder operation means, the script file having the virtual folder hierarchy after file operation is stored in the memory. And a control means for storing the means in the means.

That is, in a non-rewritable recording medium such as a CD-R, a file such as an image file is provided, along with information indicating the corresponding relationship between the actual folder hierarchy and the virtual folder hierarchy of the file and unique identification information. Script file and has been written.

When the recording medium is mounted on the reading means, it is determined whether or not a script file having the same identification information as the identification information of the script file in the recording medium is stored in the storage means. Then, when it is determined that the virtual folder hierarchy is not stored, the virtual folder hierarchy is displayed based on the script file recorded in the recording medium, and when it is determined that the virtual folder hierarchy is stored, the virtual folder hierarchy is stored in the storage means. Display a virtual folder hierarchy based on script files that have the same identification information.

File operations such as new folder creation, folder deletion, file movement, and file deletion can be performed within the displayed virtual folder hierarchy, and a script file having the result of the file operation is stored in the storage means. It As a result, when the recording medium on which the file operation has been performed is attached next time, the virtual folder hierarchy can be displayed based on the script file stored in the storage means, and the optimized recording medium browsing can be performed.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of a file display device according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a hardware configuration example of a file display device according to the present invention.

As shown in FIG. 1, this file display device is composed of, for example, a personal computer, and mainly stores a central processing unit (CPU) 10 for controlling the operation of each component and a control program for the device. Reading from the main memory 12, which is a work area when the program is executed, the operating system (OS) of the personal computer, the program for displaying files, various application software, the hard disk device 14 in which user images and the like are stored, and the CD-ROM CD-R / that can read and write to and CD-R
An RW device 16, a display memory 18 for temporarily storing display data, a monitor device 20 such as a CRT monitor or a liquid crystal monitor for displaying images and characters based on image data, character data, etc. from the display memory 18, and a keyboard. 22 and
The mouse 24 as a position input device, a mouse controller 26 that detects the state of the mouse 24 and outputs signals such as the position of the mouse pointer on the monitor device 20 and the state of the mouse 24 to the CPU 10, and the above-described components are connected. And a bus 28 that operates.

Since the personal computer having the above-mentioned configuration is well known except for the file display program stored in the hard disk device 14, detailed description of each component will be omitted.

Next, the recording medium (CD-
The recording structure of R) will be described.

When the user designates a folder in which image files are stored in the lower layer on the hard disk device 14 and instructs the backup to the CD-R, a predetermined album creating program causes all the layers below the folder to be specified. Is arranged into CD writing data suitable for recording on the CD-R, and then written on the CD-R by the CD-R / RW device 16.

FIG. 2 is a diagram showing how the recording structure is converted from the tree structure of the hard disk device 14 into the tree structure of CD writing data.

For example, when the "TestData" folder is selected from the tree structure of the hard disk drive 14 shown in FIG. 2A, folders and image files below this folder are recorded as shown in FIG. 2B. Converted to structure.

That is, DCF image root directory DC
DCF folders (100_FUJI, 101_FUJI) in the same layer are created directly under IM (Digital Camera IMages), and the image files corresponding to each DCF folder are copied.

The DCF folder and the image file thus created are automatically generated with a folder name and a file name based on a predetermined naming rule.

In this embodiment, the DCF (Design rul
e for Camera File system: Unified recording format of digital cameras) Folder names and file names are automatically generated based on the regulations, and the folder names and file names are renamed in a format that is easy to manage.

Further, the CD-R includes the DCF on the CD-R.
Information indicating the correspondence between the specified real folder hierarchy and the folder hierarchy (virtual folder hierarchy) before conversion of the recording structure, and C
The D-R unique ID (Identification) is written as a script file. FIG. 3 shows a description example of the script file. The unique ID shown in FIG. 3 indicates the date and time of writing to the CD-R, and indicates that the date and time of writing was 2001/12/26 19:37:40.

Next, the file operation and display control on the CD-R will be described.

As shown in the flow chart of FIG. 4, it is judged whether or not the CD-R in which the CD writing data including the script file is recorded is inserted into the CD-R / RW device 16 (step S10), When the CD-R is inserted, the unique ID of the CD-R is read (step S12).

Subsequently, the read unique I is stored in the internal memory of the file display device (for example, the storage area for storing the script file of the hard disk device 14).
It is determined whether or not a script file whose unique ID matches D is stored (step S14).

If a script file having a matching unique ID is stored in the internal memory, the unique I
If the script file with the matching D is read from the internal memory (step S16) and the script file with the matching unique ID is not stored in the internal memory (when the CD-R is first inserted), the script file is read from the CD-R. Is read (step S18).

Next, the virtual folder hierarchy is displayed based on the read script file, and the file operation and the main image of the image file are displayed (step S20).

FIG. 5 shows a virtual folder hierarchy displayed on the monitor device 20 based on the script file shown in FIG. 3, in which the “first day” folder is selected and “coast.JPG” and “remote island” are selected. It shows about the case where the image file of ".FPX" is displayed.

Here, as shown in FIG. 6, the image file of "coast.JPG" can be moved within the virtual folder hierarchy by dragging and dropping it into the "sea bathing" folder. Further, the file operation is not limited to the above-mentioned movement of the image file, and new folder creation, folder deletion, file deletion and the like are possible.

When the image file of "Island.FPX" is clicked on FIG. 5, the file path on the CD-R (101-0002) associated with this virtual file path is displayed.
The image file uniquely identified by (see FIG. 3) can be opened and the image can be displayed.

Returning to FIG. 4, in step S22, it is determined whether or not to end the file display, and if there is an instruction input to end the file display, then an instruction to return the virtual folder hierarchy to the initial state is given. It is determined whether or not there is an input (step S24).

If there is no instruction input for returning the virtual folder hierarchy to the initial state, it is judged in step S20 whether or not a file operation is performed (step S26). If a file operation is performed, The script file in the internal memory is updated to the script file having the virtual folder hierarchy after the file operation (step S28).

For example, when the file operation for moving the image file "shore.JPG" to the folder "sea bathing" is performed as described above (see FIG. 6), the script file shown in FIG. It can be rewritten to the script file shown. If a file operation is performed when the CD-R is inserted for the first time, a script file having a virtual folder hierarchy after the file operation is stored in the internal memory.

When an image file is opened and displayed on the monitor device 20, the history of the number of times the image is displayed is also recorded in the script file, and when the file operation for deleting the image file is performed, the file is deleted. Flags are recorded in the script file.

FIG. 8 shows a script file that is updated when the image of the "remote island.FPX" image file is displayed once and the "mountain peak.tif" image file is deleted. In the figure, numbers indicate the number of times of display, and "-1" indicates a file deletion flag.

Now, when the CD-R is inserted and the script file shown in FIG. 8 is read from the internal memory as the script file whose unique ID matches, the virtual folder hierarchy shown in FIG. 9 is displayed. Become so.

That is, according to the display count history described in the script file, the virtual folder hierarchy is rearranged and displayed in descending order of display count. In this example, the image count of the image file of "Island.FPX" is the highest (see Fig. 8), so the folder that contains the image file of "Island.FPX" in the lower hierarchy is higher than other folders. Is displayed in.

The image file of "mountain peak.tif" having the file deletion flag "-1" is not displayed even if the "mountain peak" folder is clicked.

Returning to FIG. 4, in step S26,
When no file operation is performed, the script file in the internal memory is not updated and ends. If no file operation is performed when the CD-R is inserted for the first time, the script file recorded on the CD-R is stored in the internal memory as it is.

On the other hand, in step S24, if there is an instruction input for returning the virtual folder hierarchy to the initial state, the script file recorded on the CD-R is overwritten and saved regardless of whether or not there is a file operation. The virtual folder hierarchy can be returned to the initial state (step S30).

[0044]

As described above, according to the present invention, C
Data such as image files recorded in a non-rewritable recording medium such as D-R can be displayed hierarchically,
In addition, file operations such as moving and deleting files and folders can be performed, and when the file of the recording medium is displayed next time, the recording medium can be browsed in the previously operated state (optimized state). Further, even with the same recording medium, different script files can be created for each file device according to the file operation result, and various display modes can be provided.
