The microprocessor 14 adds the corresponding image file name or scenario file name to the scenario file data each time the thumbnail image 46 or the menu 47 is continuously dropped in the palette area 48 (S8 in FIG. 9).
[0043]
When the palette area 48 is double-clicked on the edit screen B (S9 in FIG. 9), the display driver unit 17 changes the display screen to the edit screen E (S11 in FIG. 9).
Further, when the video edit button 45a is clicked on the edit screen B (S12 in FIG. 9), the display driver unit 17 changes the display screen to the video edit screen (S13 in FIG. 9).
[0044]
The microprocessor 14 repeatedly executes these series of operations until the OK button 45 is pressed.
On the other hand, when the OK button 45 is clicked on the edit screen B (S14 in FIG. 9), the display driver unit 17 returns the display screen to the edit screen A (S15 in FIG. 9).
As described above, on the editing screen B, a “scenario file that defines the playback order” is mainly newly created.
[0045]
(Edit screen C)
FIG. 18 is a diagram showing the edit screen C.
In the editing screen C, a thumbnail image 51 of “scenario file selected from menu in editing screen B” is displayed on the upper left of the screen. Below the thumbnail image 51, a motion REC button 52 and an OK button 53 are displayed.
[0046]
In addition, a special effect check box 54 is displayed in a column at the upper right of the screen, and a repeat count edit box 55 is displayed below the special effect check box 54.
Hereinafter, the operation of the embodiment on the edit screen C will be described based on the flowchart shown in FIG.
[0047]
First, the display driver unit 17 displays the editing screen C on the display screen (S16 in FIG. 10).
The microprocessor 14 reads from the magneto-optical recording medium 13 the “scenario file that defines the playback mode” selected on the editing screen B (S17 in FIG. 10).
[0048]
When the “addition” column is selected in the editing screen B (FIG. 17), the microprocessor 14 newly creates a “scenario file that defines the playback mode”.
Here, the data structure of the “scenario file that defines the playback mode” is shown in FIG. In this data structure, the next data is stored in order from the beginning of the data indicated by the pointer pa.
[0049]
1) Scenario file name
2) Relevant source image file name
3) Playback start point
4) When playback ends
5) Playback speed (pause, reverse playback, fast forward, etc. are stored in time series)
6) Number of playback repetitions
7) Special effects (fade in, wipe in, etc.)
8) Audio playback mode (stores volume etc. in time series)
The microprocessor 14 updates the corresponding data in the scenario file each time the special effect check box 54 and the repetition count edit box 55 are changed (S18 in FIG. 10).
[0050]
On the other hand, when the motion REC button 52 is clicked on the edit screen C (S19 in FIG. 10), the display driver unit 17 displays the edit screen D on the display screen (S20 in FIG. 10).
The microprocessor 14 repeatedly executes these series of operations until the OK button 53 is pressed.
[0051]
On the other hand, when the OK button 53 is clicked on the edit screen C (S21 in FIG. 10), the display driver unit 17 returns the display screen to the edit screen B (S22 in FIG. 10).
As described above, in the editing screen C, data update of “scenario file that defines the playback mode” is mainly performed.
(Edit screen D)
FIG. 19 is a diagram showing an editing screen D.
[0052]
In the editing screen D, a playback screen 60 is displayed on the left side of the screen, and a reverse fast forward button 62, a reverse playback button 61, a stop button 63, a pause button 64, a playback button are displayed on the lower side of the playback screen 60 in order from the left side. 65 and fast-forward button 66 are displayed.
An OK button 67 is arranged at the upper right of the screen, and a start setting button 68, an end setting button 69, and a confirmation button 70 are displayed at the middle of the right side of the screen.
[0053]
Furthermore, a time display box 71 for displaying the playback time and a volume adjustment bar 72 for adjusting the playback volume are displayed at the lower right of the screen.
Hereinafter, the operation of the embodiment in the editing screen D will be described based on the flowchart shown in FIG.
First, the display driver unit 17 displays the editing screen D on the display screen (S25 in FIG. 11).
[0054]
In the editing screen D, the microprocessor 14 captures a manual reproduction operation for the reproduction button 65 and the like.
Here, the microprocessor 14 reads from the magneto-optical recording medium 13 the image file that is the source of the “scenario file selected in the editing screen B”.
[0055]
The image file read out in this manner is decompressed by the image compression / decompression unit 15 and sequentially stored in the image memory 16.
On the other hand, the display driver unit 17 reproduces an image from the image memory 16 in accordance with a reproduction operation message given from the microprocessor 14.
For example, when the fast-forward button 66 is pressed, the display driver unit 17 reads images from the image memory 16 every several frames and sequentially displays them on the playback screen 60.
[0056]
When the pause button 64 is pressed, the display driver unit 17 repeatedly reads out an image for one frame from the image memory 16 and displays it on the playback screen 60.
When the start setting button 68 is clicked during such a playback period, the microprocessor 14 writes the frame number of the image currently displayed on the playback screen 60 in the data area at the playback start time in the scenario file. .
[0057]
From this point, the microprocessor 14 writes the change in the reproduction speed into the reproduction speed data area in the scenario file.
Further, when the volume adjustment bar 72 is operated, the microprocessor 14 writes the change in the reproduction volume in the data area of the audio reproduction form in the scenario file.
[0058]
Here, when the end setting button 69 is clicked, the microprocessor 14 writes the frame number of the image currently displayed on the playback screen 60 in the data area at the end of playback of the scenario file (S26 in FIG. 11).
The microprocessor 14 repeatedly executes these series of operations until the OK button 67 is pressed.
[0059]
On the other hand, when the OK button 67 is clicked on the edit screen D (S27 in FIG. 11), the display driver unit 17 returns the display screen to the edit screen C (S28 in FIG. 11).
Through the above-described operation, on the editing screen C, the manual reproduction operation is automatically recorded in the scenario file.
(Edit screen E)
FIG. 20 is a diagram showing an editing screen E.
[0060]
On the edit screen E, an OK button 76 is displayed at the upper right of the screen, and thumbnail images 75 are displayed in several rows in the middle of the screen.
In the lower left of the screen, a scroll button 77 for scrolling the column display of thumbnail images 75 and a confirmation operation button 78 for confirmation are displayed.
Hereinafter, the operation of the embodiment on the editing screen E will be described based on the flowchart shown in FIG.
[0061]
First, the display driver unit 17 displays the editing screen E on the display screen (S30 in FIG. 12).
Next, the microprocessor 14 captures a scenario file created using the palette area 48 of the editing screen B or the like. The display driver unit 17 displays the thumbnail images 75 in a row according to the playback order defined in the scenario file (S31 in FIG. 12).
[0062]
Here, when one thumbnail image 75 is dragged, the display driver unit 17 displaces the thumbnail image 75 following the movement of the drag operation.
Further, when this thumbnail image 75 is dropped between two thumbnail images, the thumbnail image 75 is inserted between them and the entire display position is rearranged (S32 in FIG. 12).
[0063]
The microprocessor 14 rearranges data indicating the reproduction order in the scenario file which is equal to the arrangement order of the thumbnail images 75 (S33 in FIG. 12).
The microprocessor 14 repeats these series of operations until the OK button 76 is pressed.
On the other hand, when the OK button 76 is clicked on the edit screen E (S34 in FIG. 12), the display driver unit 17 returns the display screen to the edit screen B (S35 in FIG. 12).
[0064]
Through the editing operation described above, on the editing screen E, the data indicating the playback order in the scenario file can be easily changed.
When the reproduction operation button 78 for confirmation shown in FIG. 19 is operated during the editing operation described above, the microprocessor 14 generates a child window for the reproduction screen, Image files are played in order according to the current playback order.
[0065]
(Playback operation)
FIG. 21 is a diagram showing a display screen during reproduction.
A reproduction screen 80 is displayed large on the screen, and a reproduction operation button 82 is displayed below the reproduction screen 80.
Hereinafter, the reproduction operation of the embodiment will be described based on the flowchart shown in FIG.
[0066]
First, the display driver unit 17 displays the screen frame of the playback screen 80 (S41 in FIG. 13).
Next, the microprocessor 14 determines whether the file whose thumbnail is selected on the initial screen is an image file or a scenario file (S42 in FIG. 13).
[0067]
Here, when the image file is selected as a thumbnail, the microprocessor 14 reads the image file from the magneto-optical recording medium 13 via the disk drive unit 12 (S43 in FIG. 13).
The image compression / decompression unit 15 decompresses the data of the image file and sequentially stores it in the image memory 16. The display driver unit 17 sequentially displays the image information in the image memory 16 on the reproduction screen 80 (S44 in FIG. 13).
[0068]
The display driver unit 17 returns the display screen to the initial screen after completing the reproduction of the image file (S45 in FIG. 13).
On the other hand, when the scenario file is selected as a thumbnail in step S42, the microprocessor 14 determines whether the playback order or the playback mode is defined based on the data structure of the scenario file (S46 in FIG. 13).
[0069]
Here, in the case of a scenario file in which a reproduction format is defined, the microprocessor 14 reads out the scenario file and the related image file from the magneto-optical recording medium 13 via the disk drive unit 12 (S47 in FIG. 13).
Next, the microprocessor 14 acquires data at the playback start time and playback end time from the scenario file data structure, and transfers these data to the image compression / decompression unit 15.
[0070]
The image compression / decompression unit 15 decompresses the data of the image file from before and after the frame at the start of reproduction and sequentially stores it in the image memory 16.
The display driver unit 17 transmits the frame number of the image in the image memory 16 to the microprocessor 14.
In accordance with this frame number, the microprocessor 14 transmits corresponding data such as the playback speed, the playback mode of voice, and special effects in the scenario file to the display driver unit 17.
[0071]
The display driver unit 17 changes the frame display time interval, the reproduction mode of the audio data included in the image file, the special effect, and the like in synchronization with the corresponding data (S48 in FIG. 13).
The image compression / decompression unit 15 decompresses the frame at the end of playback and ends the decompression process of the image file. The display driver unit 17 returns the display screen to the initial screen after the reproduction of the image in the image memory 16 is completed (S49 in FIG. 13).
[0072]
On the other hand, when it is determined in step S46 that the scenario file defines the playback order, the microprocessor 14 reads the scenario file from the magneto-optical recording medium 13 via the disk drive unit 12.
Here, the microprocessor 14 hierarchically follows the reproduction order, and expands the data in the reproduction order on the memory inside the microprocessor 14 (S50 in FIG. 13).
[0073]
That is, in the case as shown in FIG.
(Image file B → Scenario file C → Image file D)
Data is recorded. Therefore, the microprocessor 14 reads the scenario file C defining the playback order in a hierarchical manner.
In this scenario file C,
(Image file E → Image file F → Scenario file G)
Data is recorded. Here, since the scenario file G defines the reproduction mode, the reproduction order does not follow any further.
[0074]
As a result, the playback order expanded on the memory is
(Image file B → Image file E → Image file F → Scenario file G → Image file D)
It becomes.
Here, the microprocessor 14 searches for a connection location between the scenario files defining the reproduction forms, and determines whether or not there is a contradiction in a special effect or the like of the connection location based on a predetermined comparison table or the like. (S51 in FIG. 13).
[0075]
For example, if fade-out and wipe-in are defined mutually, it is determined that a contradiction occurs.
When such a contradiction occurs, the microprocessor 14 deletes the corresponding data in the subsequent scenario file in order to give priority to the special effect of the preceding scenario file (S52 in FIG. 13).
[0076]
The microprocessor 14 overwrites the corrected scenario file on the magneto-optical recording medium 13 (S53 in FIG. 13).
In the state where the contradiction is resolved in this way, the microprocessor 14, the image compression / decompression unit 15 and the display driver unit 17 sequentially reproduce the image file or the scenario file in accordance with the reproduction order expanded on the memory (S54 in FIG. 13). ).
[0077]
The display driver unit 17 returns the display screen to the initial screen after the reproduction of the image in the image memory 16 is completed (S55 in FIG. 13).
(Video editing screen)
FIG. 22 is a diagram showing a video editing screen.
A main screen 84 is displayed large on the screen, and an OK button 85, a file menu 86, and a special effect menu 87 are displayed on the right side of the main screen 84. By clicking on this special effect menu 87, a selection menu such as trimming adjustment, addition of a specific screen frame, and color tone adjustment is displayed.
[0078]
Below the special effect menu 87, a file list 88 for displaying a list of scenario files is displayed.
Further, a sub-screen 89 for confirming the screen effect by the special effect menu 87 is displayed at the lower right of the main screen 84. In the lower left of the main screen 84, a record button 90 and a playback button 91 are displayed.
[0079]
The playback button 91 performs the same function as the playback operation button 82 in the above-described playback screen (FIG. 21).
Hereinafter, the operation related to the recording button 90 will be described based on the flowchart shown in FIG.
First, the microprocessor 14 acquires the file name of the scenario file via the disk drive unit 12, and displays the list in the file list 88 (S61 in FIG. 14).
[0080]
Next, the microprocessor 14 acquires manual selection of the file list 88 via the touch panel 18a (S62 in FIG. 14).
Such an operation is repeated until the recording button 90 is pressed. Note that if the special effect menu 87, the playback button 91, or the like is operated during this period, the microprocessor 14 executes the corresponding operation.
[0081]
Here, when the record button 90 is pressed (S63 in FIG. 14), the microprocessor 14 determines based on the data structure whether the selected scenario file defines the playback order or the playback mode (S64 in FIG. 14). .
Here, in the case of a scenario file in which a reproduction form is defined, the microprocessor 14 reads out the scenario file and the related image file from the magneto-optical recording medium 13 via the disk drive unit 12 (S65 in FIG. 14).
[0082]
Next, the microprocessor 14 acquires data at the playback start time and playback end time from the scenario file data structure, and transfers these data to the image compression / decompression unit 15.
The image compression / decompression unit 15 decompresses the data of the image file from before and after the frame at the start of reproduction and sequentially stores it in the image memory 16.
[0083]
The display driver unit 17 transmits the frame number of the image in the image memory 16 to the microprocessor 14.
In accordance with this frame number, the microprocessor 14 transmits corresponding data such as the playback speed, the playback mode of voice, and special effects in the scenario file to the display driver unit 17.
[0084]
The display driver unit 17 changes the frame display time interval, the playback mode of audio data included in the image file, special effects, and the like in synchronization with the corresponding data.
The image data processed based on the scenario file as described above is reproduced and displayed on the main screen 84 and is sequentially stored in the image memory 16 (S66 in FIG. 14).
Each time processed image data is stored in the image memory 16 for a predetermined time, the image compression / decompression unit 15 temporarily interrupts the decompression operation and compresses the image data.
[0085]
The disk drive unit 12 creates a new image file on the magneto-optical recording medium 13, and sequentially stores the compressed image data in the image file (S67 in FIG. 14).
The image compression / decompression unit 15 ends the decompression process of the image file when the decompression operation at the end of the reproduction is completed. The display driver unit 17 waits for the storage of the image data to be completed, and returns the display screen to the initial screen (S68 in FIG. 14).
[0086]
On the other hand, if it is determined in step S 64 that the scenario file defines the playback order, the microprocessor 14 reads the scenario file from the magneto-optical recording medium 13 via the disk drive unit 12.
Here, the microprocessor 14 hierarchically follows the reproduction order as shown in FIG. 24, and expands the data in the reproduction order on the memory inside the microprocessor 14 (S69 in FIG. 14).
[0087]
Here, the microprocessor 14 searches for a connection location between the scenario files defining the reproduction forms, and determines whether or not there is a contradiction in a special effect or the like of the connection location based on a predetermined comparison table or the like. (S70 in FIG. 14).
If a contradiction occurs, the microprocessor 14 deletes the corresponding data in the subsequent scenario file in order to give priority to the special effect of the preceding scenario file (S71 in FIG. 14).
[0088]
The microprocessor 14 overwrites the corrected scenario file on the magneto-optical recording medium 13 (S72 in FIG. 14).
In the state where the contradiction is resolved in this way, the microprocessor 14 reads out the image file through the disk drive unit 12 in the order of reproduction.
Thus, the image data in the image file read in order based on the scenario file are sequentially connected on the image memory 16 and reproduced and displayed on the main screen 84 (S73 in FIG. 14).
[0089]
The image data connected in this way is sequentially compressed through the image compression / decompression unit 15 and then sequentially output to the disk drive unit 12.
The disk drive unit 12 creates a new image file on the magneto-optical recording medium 13, and sequentially stores the connected image data in the image file (S74 in FIG. 14).
The display driver unit 17 returns the display screen to the initial screen after the storage of the linked image data is completed (S75 in FIG. 14).
[0090]
(Effects of this embodiment)
As described above, in this embodiment, the scenario file is hierarchically traced to reconstruct the playback order, so that the file structure can be simplified for each scenario file.
In addition, the edited scenario file can be incorporated into the scenario file as it is. Therefore, it is not necessary to create an intermediate image file during editing. As a result, the capacity of the recording medium can be used efficiently without waste.
[0091]
Furthermore, since a scenario file is created by automatically recording a manual reproduction operation, the scenario file can be created easily.
In addition, since a scenario file can be created based on an advanced editing operation, complicated editing items that cannot be specified by a manual reproduction operation can be included in the scenario file.
[0092]
Furthermore, since the contradiction of the scenario file is automatically corrected according to a predetermined priority order, there is no possibility that the image file editing work along the scenario file will be hindered.
In this embodiment, since the scenario files defining the playback mode and playback order are separated, the data structure of the scenario file is simplified, and the information processing load required to interpret the data structure can be reduced. Is possible.
[0093]
Further, in the present embodiment, the scenario file can be read and the image file can be reproduced, so that the editing operation can be performed while quickly confirming the editing result.
In the present embodiment, a camera unit 11a that captures a subject image and generates an image file is provided. With such a configuration, it is possible to create a scenario file immediately after the image file captured by the camera unit 11a. Therefore, it is possible to eliminate the inconvenience of performing editing work while remembering the shooting contents after a lapse of time.
[0094]
In the above-described embodiment, the scenario file that defines the playback mode and the playback order is separated, but both data structures may be included in one scenario file.
In the embodiment described above, the image file and the scenario file are separated from each other. However, the scenario file may be recorded in a part of the image file.
[0095]
Further, in the above-described embodiment, the magneto-optical recording medium 13 is employed as the recording medium 1. However, the present invention is not limited to the material and shape of the recording medium 1, and a recording medium capable of recording image information. 1 may be sufficient. For example, an optical recording medium, a magnetic recording medium, or a semiconductor recording medium may be used.
[0096]
In the above-described embodiment, the case where the image file and the scenario file are recorded on one recording medium is described. However, the present invention is not limited to this description. The scenario file and the image file may be recorded separately on a plurality of recording media.
Furthermore, in the above-described embodiment, the case where the edited image file is recorded on the recording medium containing the original image file is described, but the present invention is not limited to this description. The recording medium on which the edited image file is recorded may be different from the recording medium on which the original image file is recorded.
[0097]
In the above-described embodiment, when the scenario file has a contradiction, the preceding image reproduction is automatically prioritized. However, the present invention is not limited to this. For example, the subsequent image reproduction may be automatically prioritized, or the prioritized side may be set in advance for each type of contradiction. Further, when a contradiction occurs, a priority instruction from the outside may be received via the touch panel 18a.
[0098]
Furthermore, in the above-described embodiment, inconsistencies in the scenario file are automatically corrected during playback or video editing, but the present invention is not limited to this. For example, during the editing operation as shown in FIG. 24, the contradiction of the scenario file may be automatically corrected, or the operator may be warned of the contradiction. With such a configuration, it becomes possible to quickly find inconsistencies during editing of the scenario file and correct the inconsistencies quickly and easily.
[0099]
Further, in the above-described embodiments, some examples of the reproduction mode (including special effects) have been described, but the present invention is not limited to this. Generally, the reproduction form here may be any form that appears on the screen or sound during reproduction.
Furthermore, it is assumed that an image file (image file that does not exist at that time) to be taken from now on by the camera unit 11a or the like, and file management means for handling such an assumed image file in the same manner as an existing image file. It may be added to the described invention.
[0100]
By adding such a file management means, it is possible to previously incorporate an image file to be shot in the reproduction order data in the scenario file.
Therefore, a scenario file can be created in advance according to a shooting plan such as a storyboard. In addition, by preparing a scenario file in advance, it is possible to complete an edited video work at the same time as a series of shooting is completed.
[0101]
【The invention's effect】
  As explained above, claim 1Or any one of claims 3In the invention described in the above, the image file is automatically edited in accordance with the playback order or playback mode in the scenario file.
  Usually, such a scenario file is composed mainly of data in the order of reproduction or reproduction form, and therefore requires a smaller amount of information than an image file containing image information itself. Therefore, the recording capacity of the recording medium can be used efficiently.
[0102]
  In particular, editing operations by the operator need only be performed by creating a new scenario file or updating data. As a result, it is less necessary to create and save intermediate image files one by one during editing. Therefore, the editing operation can be speeded up and the recording capacity of the recording medium can be used efficiently without waste.The
[0105]
  Claim 4In the invention described in the above, inconsistencies in the scenario file are automatically corrected according to a predetermined priority order and correction instruction. Therefore, even if there is a contradiction in the scenario file, image editing can be performed to the extent that there is no problem.
  Claim 5In the invention described in (1), it is possible to roughly check the image file after completion of editing at the stage of the scenario file.
