Description

  The present invention relates to an image file editing apparatus that edits an image file (which may include audio data) on a recording medium, and more particularly to an image file editing apparatus that easily edits an image file on a removable recording medium. About.

2. Description of the Related Art Conventionally, an image file editing apparatus that performs editing operations such as connection processing and composition processing on an image file composed of a moving image or a still image is known.
By performing such editing work, for example, it is possible to create a single video work by appropriately connecting image files captured in a plurality of scenes at the time of imaging.
In recent years, with the development of digital signal processing, programs for realizing the above-described image file editing apparatus using a computer have been developed.

FIG. 7 is a diagram showing a display screen of a computer in this type of program.
In FIG. 7, a thumbnail display section 52 for displaying a list of thumbnail images (thumbnail) is displayed at the lower left of the display screen 51. On the upper side of the display screen 51, an editing area 53 for appropriately arranging thumbnail images by drag and drop operation is displayed. In addition, a file menu 54 for performing file operations is displayed in a line at the top of the display screen 51.

Hereinafter, an operator's interactive operation on this screen will be described.
First, the operator operates the file menu 54 to select an image file on the recording medium.
The computer partially reads the head image from the selected image file, reduces the pixel density of the head image, and generates a thumbnail image. The thumbnail images generated in this way are displayed as a list on the thumbnail display unit 52.

In FIG. 7, thumbnail images of the image file A and the image file B are displayed as a list.
In this state, the operator drags and drops the thumbnail image on the thumbnail display unit 52 to the editing area 53.
Then, the computer arranges the thumbnail images in a line according to the drop positions of the thumbnail images.

Here, when the playback button (triangle mark) at the upper right of the editing area 53 is clicked, the computer sequentially reads out the corresponding image files in the order of the thumbnail images arranged in the editing area 53. The computer sequentially reproduces the image file read in this way on a child window (not shown) that is temporarily created on the display screen 51.
When “compile movie” is selected in the file menu 54 or the like, the computer sequentially connects the corresponding image files in the order of the thumbnail images arranged in the editing area 53 to generate one image file. .

In general, since an image file has a large file capacity, a series of image files cannot be stored in one recording medium, and are often recorded separately on a plurality of recording media.
For example, when shooting a long event such as a wedding ceremony with a digital video camera or the like, shooting is not completed with one recording medium, and image files are created by dividing into a plurality of recording media.

When editing an image file recorded separately on a plurality of recording media in this way, the operator appropriately replaces the recording medium according to the progress of image editing while accurately grasping the contents of each recording medium. Must be done.
An object of the present invention is to provide an image file editing apparatus capable of accurately collating recording media.

The image file editing apparatus according to the present invention includes medium drive means, editing means, storage means, display means, and information processing means. The medium drive means can write and read a plurality of moving image files with respect to a removable recording medium. The editing means edits the moving image file on the recording medium loaded in the medium drive means. The storage means includes at least one of the file name, file capacity, and number of files of the moving image file recorded on the recording medium, and stores ID information for identifying the recording medium. The display means displays the moving image file of the recording medium on the display unit. The information processing means stores the ID information recorded on the recording medium in the storage means using the medium drive means during the period from when the recording medium is loaded into the medium drive means until it is ejected. Based on the stored ID information, identification information of moving image files written on a recording medium not loaded in the medium drive means is displayed in a list on the display unit.

Preferably, the identification information may be a creation date and time of the moving image file.
Preferably, the identification information may be a file name of a moving image file .

Preferably, the identification information may be a thumbnail that is the first frame of the moving image file.

Preferably, the information processing means includes at least a part of the ID information of the recording medium loaded during the period from when the recording medium is loaded into the medium drive means until it is ejected, and the ID stored in the storage means. You may collate with some information.

Preferably, the information processing means determines whether or not ID information is recorded on the recording medium in response to loading of the recording medium into the medium driving means, and the ID information is not recorded on the recording medium. If it is determined, ID information may be recorded on the recording medium.

  In the image file editing apparatus of the present invention, identification information of a moving image file written in a recording medium not loaded in the medium drive means can be displayed in a list on the display unit based on the ID information. Therefore, the operator can execute image editing between a plurality of recording media simply and easily. In one embodiment of the present invention, when a recording medium is newly loaded, the image files on the recording medium are automatically displayed as a list. Therefore, it is not necessary to consciously display a list of image files every time the recording medium is replaced.

  In another embodiment of the present invention, since information originally existing on the recording medium is used as ID information, it is not necessary to write extra ID information on the recording medium. As the ID information, for example, information originally existing on the recording medium can be used singly or in combination. In such a case, if the same ID information does not exist as a result of collation with the ID information acquired in the past, it is found that the current recording medium is a newly mounted recording medium. On the other hand, the image file editing apparatus may automatically record ID information for each recording medium. In such a case, if the unique ID information is not found from the recording medium, it is determined that the current recording medium is a newly mounted recording medium. Furthermore, since unnecessary ID information is not written to the recording medium, it is possible to reliably check the read-only recording medium.

  In another embodiment of the present invention, the unique ID information is written on the list-displayed recording media, so that there is little possibility that the ID information is changed separately, and the recording media can be accurately verified.

Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
Figure 1 is a functional block diagram of a first embodiment type status.
FIG. 2 is a diagram illustrating an appearance of the present embodiment.
1 and 2, a camera unit 11a, which is an accessory, is rotatably attached to the side surface of the main body 11 of the image file editing apparatus, and a shooting lens 12 that forms a subject image is mounted on the camera unit 11a. Installed.

The optical axis of the photographic lens 12 is bent in the camera unit 11a, and the light receiving surface of the image sensor 13 composed of a CCD image sensor is disposed on the extension of the optical axis.
The photoelectric output of the image sensor 13 is connected via an A / D converter 14 to a video signal processor 15 that performs white balance adjustment and gamma correction.
The image output of the video signal processing unit 15 is connected to the system bus 18 of the microprocessor 17 via the high efficiency encoding unit 16.

The system bus 18 is connected to a memory 19, a disk drive unit 20, a liquid crystal display unit 22, a touch panel 22a, and the like.
The touch panel 22a is attached to the display screen of the liquid crystal display unit 22 and senses the contact position of a finger or a pen.
The disk drive unit 20 includes a head unit for reading and writing information with respect to the magneto-optical recording medium 23 inserted from the outside, a drive mechanism for driving the head unit, and the like.

The liquid crystal display unit 22 includes a video memory that can be rewritten via the system bus 18, a liquid crystal drive circuit that reads data from the video memory at any time and displays the data on a screen, and a liquid crystal display screen.
FIG. 3 is a diagram showing a display example of the liquid crystal display unit 22.
In FIG. 3, on the display screen of the liquid crystal display unit 22, two child windows including a first area 30a and a second area 30b are displayed. In these areas 30a and 30b, thumbnail images 31 are displayed in a list.

Further, on the lower side of the display screen of the liquid crystal display unit 22, a playback operation button 33 for operating playback of an image file, a connection button 34 for connecting image files, and a mode switching of the inter-media editing mode. An inter-medium edit button 35 for performing the above is displayed in a row .

4 and 5 are flowcharts for explaining the operation of this embodiment.
Hereinafter, the operation of this embodiment will be described with reference to these drawings.
First, when the main body 11 is turned on, a screen as shown in FIG. 3 is displayed on the liquid crystal display unit 22. The thumbnail image 31 is not displayed on the display screen in the initial state.
Normally, when an operation button on the screen is pressed with a finger or a pen in this state, the microprocessor 17 senses the pressed position via the touch panel 22a. In the microprocessor 17, a message corresponding to the pressed position is generated at any time.

First, the microprocessor 17 determines whether or not it is an inter-medium editing mode (step S1). In a default state, a known operation mode (in-medium editing mode) for performing image editing only on an image file on one magneto-optical recording medium 23 is set. Therefore, usually, the microprocessor 17 shifts the operation to the in-medium editing mode (step S2).
On the other hand, when the message “intermediate edit button 35 has been pressed” occurs, the microprocessor 17 shifts to an operation mode (intermediate edit mode) in which image editing is performed across a plurality of magneto-optical recording media 23. The following operation is executed.

First, the microprocessor 17 instructs the disk drive unit 20 to perform appropriate reading, and waits until significant read information is obtained (step S3). When significant read information is obtained in this state, the microprocessor 17 determines that the magneto-optical recording medium 23 has been inserted into the disk drive unit 20.
Next, the microprocessor 17 reads combination information such as the file name, file capacity, and number of files on the magneto-optical recording medium 23 through the disk drive unit 20 as ID information. The microprocessor 17 records these ID information in the memory 19 (step S4).

The microprocessor 17 partially reads the image file on the magneto-optical recording medium 23 via the disk drive unit 20 and acquires the head image of the image file. The microprocessor 17 performs pixel density conversion on the head image to generate a thumbnail image 31 (step S5).
The microprocessor 17 sequentially transfers the thumbnail images 31 generated in this way to the video memory of the liquid crystal display unit 22 and displays a list in the first area 30a (step S6).

In this state, the microprocessor 17 waits until significant read information is obtained again (medium reinsertion) after significant read information from the magneto-optical recording medium 23 is interrupted once (discharge of the medium). .
Based on such confirmation, the microprocessor 17 confirms that the magneto-optical recording medium 23 has been replaced (step S7).

Next, with respect to the replaced magneto-optical recording medium 23, the microprocessor 17 reads combination information such as a file name, a file capacity, and the number of files as ID information via the disk drive unit 20 and records it in the memory 19. (Step S8).
The microprocessor 17 collates these latest ID information with the previous ID information on the memory 19 (step S9).

As a result of the collation, when the number of matching items exceeds a predetermined number, the microprocessor 17 determines that the magneto-optical recording medium 23 has not been newly installed, and returns to step S7 to repeat the operation.
On the other hand, when the number of matching items is less than the predetermined number, the microprocessor 17 determines that the magneto-optical recording medium 23 is newly attached (step S10).

Here, the microprocessor 17 partially reads out the image file from the newly installed magneto-optical recording medium 23 and acquires the head image of the image file. The microprocessor 17 performs pixel density conversion on the head image to generate a thumbnail image 31 (step S11).
The microprocessor 17 sequentially transfers the thumbnail images 31 generated in this way to the video memory of the liquid crystal display unit 22 and displays a list in the second area 30b (step S12).

As described above, the thumbnail images 31 are displayed in a list in the two areas 30a and 30b in accordance with the new mounting of the recording medium. In this state, the microprocessor 17 waits for thumbnail selection by the operator (step S13).
Here, when a thumbnail is selected in the second area 30b (step S14), the microprocessor 17 determines the selected image file based on the pressed position of the thumbnail selection. The microprocessor 17 records the image file as it is in the memory 19 together with the selection order data (step S15). The above operation returns to step S13 and is repeated.

If a thumbnail is selected in the first area 30a during such a repetitive operation (step S14), the microprocessor 17 determines that the thumbnail selection for the previous medium has been performed, and the magneto-optical recording medium 23 is selected. A message prompting replacement is displayed on the liquid crystal display unit 22 (step S21).
In this state, the microprocessor 17 waits until the replacement of the magneto-optical recording medium 23 is completed (step S23).

When the replacement of the magneto-optical recording medium 23 is completed, the microprocessor 17 reads information such as a file name, a file capacity, and the number of files as ID information via the disk drive unit 20 (step S24).
The microprocessor 17 collates these latest ID information with the previous ID information on the memory 19 (step S25).

If the number of matching items is less than the predetermined number as a result of the collation, the microprocessor 17 determines that a different one from the previous magneto-optical recording medium 23 is loaded, and displays a warning message indicating that the recording medium is different ( Step S22) and return to step S23.
On the other hand, when the number of matching items exceeds a predetermined number, the microprocessor 17 determines that the previous magneto-optical recording medium 23 has been loaded (step S26).

In this state, the microprocessor 17 accepts the thumbnail selection in the first area 30a and records the file name of the selected image file and the data in the selection order in the memory 19 (step S27).
The operation in step S27 is repeated each time a thumbnail is selected in the first area 30a (step S28).

  If a message “the connection button 34 has been pressed” occurs during such thumbnail selection (step S29), the microprocessor 17 first connects the image files on the memory 19 sequentially in accordance with the selection order data. To do. Subsequently, the microprocessor 17 sequentially calls and connects the image files on the magneto-optical recording medium 23 according to the data and file names in the order of selection. The microprocessor 17 records the image file thus connected to the magneto-optical recording medium 23 via the disk drive unit 20 (step S30).

  With this operation, in the present embodiment, image files on the newly installed magneto-optical recording medium 23 are automatically displayed as a list. Therefore, it is not necessary to consciously display a list of image files when a recording medium is newly inserted. In addition, when the recording medium is exchanged many times, there is no confusion such as duplicating and displaying one image file on the recording medium. Furthermore, since the information originally present on the recording medium is also used as the ID information, it is not necessary to write any extra ID information on the recording medium, and the read-only recording medium can be reliably verified.

Next, another embodiment will be described.
(Second Embodiment)
Figure 6 is a flowchart illustrating the operation of the second embodiment shaped state.
Note that the structural features of the second embodiment are the same as those of the first embodiment (FIGS. 1 and 2) except that the internal functions of the microprocessor 17 are partially different.

Below, with reference to FIG. 6, the operation of the second embodiment.
The microprocessor 17 performs normal processing such as thumbnail selection and editing processing. Between these normal processes, the microprocessor 17 generates a timer interrupt at regular intervals and executes the next interrupt process.

First, the microprocessor 17 reads the volume label of the magneto-optical recording medium 23 via the disk drive unit 20 (step S41).
The microprocessor 17 determines whether or not this volume label matches predetermined ID information (step S42). This ID information is composed of a combination of appropriate characters, numbers, symbols and the like.

If the ID information matches the predetermined ID information, the microprocessor 17 determines that the list is already displayed on the magneto-optical recording medium 23 and ends the interrupt processing.
On the other hand, if it does not match the predetermined ID information, the microprocessor 17 determines that the magneto-optical recording medium 23 is newly installed. The microprocessor 17 partially reads out the image file from the magneto-optical recording medium 23, and generates a thumbnail image 31 from the head image of the image file (step S43).

The microprocessor 17 transfers the thumbnail images 31 generated in this way to the video memory of the liquid crystal display unit 22 and displays them as a list. As a result, old and new thumbnail displays coexist on the display screen (step S44).
Next, the microprocessor 17 writes predetermined ID information on the volume label of the magneto-optical recording medium 23 (step S45).

By writing ID information in this way, it is possible to reliably avoid duplication of thumbnail display when the magneto-optical recording medium 23 is inserted next time.
After such an operation, the microprocessor 17 ends the interrupt process.
In the above-described embodiment, the magneto-optical recording medium 23 is used as the recording medium. However, the present invention is not limited to the material and shape structure of the recording medium, and any recording medium capable of recording an image file. That's fine. For example, an optical recording medium, a magnetic recording medium, a memory card, or the like may be used.

  In the above-described embodiment, connection of image files has been described as an editing operation. However, the present invention is not limited to this, and any editing operation may be performed on an image file. For example, copying, moving, and image composition of image files between a plurality of recording media may be used. The image file connection processing may include special connection processing such as overlap, fade-in, fade-out, wipe-in, and wipe-out.

Furthermore, in the embodiment described above, the thumbnail image 31 is adopted as the identification information. However, the present invention is not limited to this, and the identification information may be any information that allows the operator to identify the image file. Can be adopted as. For example, character information such as a file name and a file creation date / time may be used.
In the second embodiment, ID information is written on the volume label of the recording medium. However, the present invention is not limited to the ID information writing position. It may be a predetermined location on the recording medium, and may be a management area or a data area on the recording medium.
