Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving image editing system for editing moving images digitally stored in a disk or a memory.

[0002]

2. Description of the Related Art Hitherto, to edit a video image, one video tape has been reproduced and another video tape has been recorded. Since you had to manipulate the tape, it took time to find the beginning of the video you wanted to select. In addition, adding an acoustic or visual special effect required a very complicated procedure.

[0003]

In recent years, video compression techniques have advanced, and CD-ROMs storing moving image data and D-ROMs have been developed.
VD has been developed, and a technique has been developed in which digital data of a moving image camera is recorded not on a tape but on a disk or a memory. Further, a technique for directly recording an image of a television or the like on a storage medium such as a hard disk or a PD with a personal computer has been developed.

However, AVI and MPEG are used as compression methods.
1, MPEG2, DV, and other compression methods are mixed, so that video recorded in each method can be edited if digital video data of the same compression method is used, but different technologies have been developed. A technique for editing digital video data recorded in a compression format has not been developed yet.

[0005] Also, in the editing operation on digital video data of the same compression system, a still image for title screen display is used in the same manner as the compression system of the video to be edited in order to display a title screen and a special effect of the video. To convert to the compression format or insert special effects,
The editing operation is very complicated, and the processing time is enormous. For example, after the digital video data is once decompressed into non-compressed video data, it is necessary to add a special effect and compress again. In the case of handling video data having different compression methods, a process of once converting a plurality of target video data into the same compression method is required, which further complicates the processing.

Further, in the conventional technique, an editing operation is performed on the video data itself as a result of editing, and the video data is changed. Therefore, a huge work area for an editing operation is required on a storage medium such as a hard disk. Furthermore, even when creating a work in which only a part of the edit content is changed, a huge amount of space is required for storage since new digital video data is created for each work.

Accordingly, the present invention proposes an invention relating to a new technique for editing one or a plurality of digital moving image data compressed by one or a plurality of methods.

At this time, in the example of the display unit 10 shown in FIG. 4, the new bookmark tag 414f and the pointer line 4 connecting the bookmark tag with the delimiter position are set.
16 is automatically added and displayed. New bookmark tag 4 above
For example, a bookmark name such as "1996 opening ceremony" may or may not be input to 14f. When the bookmark name is input as described above, the “1996 opening ceremony” is inserted in the “delimiter” column. By the above operation, the reproduction start point at the time of edit reproduction is set.

Next, the reproduction operation menu bar 402 is operated to display the video at the end position of the section to be reproduced, and the bookmark setting button 401 is pressed. As a result, in the second row of the edit table 201, for example, a value of (00: 03: 00: 00) is inserted in the column of “separation position”, and play is automatically performed in the column of “separation operation”. "1 is inserted in the group identifier," H8 Athletic Meet.mpg "is inserted in the column of" file name ",
“Mpeg1” is inserted in the column of “compression identifier”.

When the bookmark tag newly added by the above operation is double-clicked, the delimiter information determining unit 4
The contents of the reproduction operation data table 11, the special effect program data table 12, and the edit table 201 are displayed on a delimiter information screen 601 as shown in FIG.

Reference numerals 504a and 504b denote video file scroll buttons for scrolling the display up and down when the display of the video file does not fit in the edit assist menu 502. When adding new digital moving image data, pressing the reference button 507 displays a list of editable moving image data, and selects the corresponding digital moving image data file, “H9 Athletic Meet.mp2”. Then, the moving image file new registration area 506
The video bar is displayed on. Reference numeral 505 denotes a current position mark indicating the current reproduction position on the video bar. For example, now
The file “H9 Athletic Meet.mp2” is a video bar 503
Let it be indicated by b. Playback operation menu bar 402
Is operated to display the start point of the playback section to be used for “H9 Year Sports Day.mp2”, and press the 501a bookmark setting start point button. The bookmark setting start button 501a operates in exactly the same way as the 401 bookmark setting button.

That is, the delimiter position determining unit 3 obtains the reproduction position when the bookmark setting start button 501 a is pressed from the moving image data reproducing unit 2, and manages the edit table setting unit 6 in the seventh row of the edit table 201. of,
The value of the break position, for example, (0
0: 10: 45: 15), “Play” is written in the “Separation action” field, 1 is written in the “Group identifier” field, and the H9 Sports Day.
mp2 is written, and mpeg2 is written in the column of “compression identifier”.

Next, the reproduction operation menu bar 402 is operated to display the end point of the reproduction section desired to be used for "H9 year sports day.mp2", and the bookmark setting end point button 501b is pressed. The delimiter position determination unit 3 obtains the reproduction position when the bookmark setting start button 501 a is pressed from the moving image data reproduction unit 2, and manages the “delimiter position” in the eighth line of the edit table 201 managed by the edit table setting unit 6. "Field, the value of the delimiter position, for example, (00: 15: 00: 1
0), “Skip” is written in the “Separation operation” field, 1 is written in the “Group identifier” field,
In the “File Name” column, enter the H9 Sports Day. mp2 is written, and mpeg2 is written in the column of “compression identifier”. When the bookmark setting start point button 501a is pressed, the “separation operation”
"Play" is written in the column "No.", but "skip" is written in the column "separation operation" when the bookmark setting end point button 501b is pressed. By the above operation, H9 year sports day. This means that the start point and end point of the first playback section among the playback sections used in the file of mp2 have been set.

When the editing auxiliary menu 502 is completed, the display returns to the display as shown in FIG. Here, a bookmark tag 414 corresponding to the start point of the newly added playback section
When double-clicking on d, a separator information screen 601 is displayed. Here, "1997 opening ceremony" is entered as the bookmark name, and in the illustration setting of the special effect 604, an illustration selection and a display time of 2 seconds are entered. . As a result, the delimiter information determination unit 4 writes the 1997 opening ceremony in the “delimiter phrase” column on the seventh line of the edit table 201, writes “illustration” in the “special effect” column, and writes the “auxiliary information 2” In the column, write the contents of the illustration and data indicating the display for 2 seconds.

Similarly, the ninth and tenth lines of the edit table 201 correspond to the H9 Sports Day. This is an example in which a playback section that captures a relay is additionally registered from the file of mp2, and a telop character is displayed during playback. In contrast, the eleventh to fifteenth lines are further set by a digital video camera. An example is shown in which the captured digital moving image data file of the DV format “H10th year sports day. DV” is additionally registered and an editing operation is added. further,
The 14th line shows an example in which a new illustration display is added for 3 seconds at the position of a break position (00: 12: 15: 00) between the 13th line and the 15th line, which is a playback section. I have.
Thus, it is also easy to add a special effect to an arbitrary reproduction position later.

Next, the reproduction of the edited work will be described. The edit table storage unit 7 is operated by the operation unit 5.
One edit work is specified by specifying a group identifier from among the above, and the edit work is read out to the edit reproduction unit 8. Now, it is assumed that the edit work whose group identifier is 1 shown in FIG. 2 has been read. The edit playback unit 8 performs edit playback according to the flowchart shown in FIG.

In step S1, the edit table 20
The row parameter i indicating the row number of 1 is reset to 1. In step S2, the i-th edit table 201
Read one line of data in the line. In step S3, it is determined that the reproduction has ended. If the i-th line read in step S2 is a blank line, the reproduction is determined to be ended, "YES" is determined, the reproduction is stopped in step S12, and the edit reproduction is ended. If "NO" is determined in the step S3, the process proceeds to the reproducing operation. In step S4, it is first determined whether or not a special effect has been designated. If a special effect has been designated, a program for executing the designated special effect is transmitted to the auxiliary information 2.
Start with parameter data in. Immediately after the start of the special effect program, or immediately after the end of the special effect program, the process shifts to step S5 to read the delimiter operation on the i-th line of the edit table 201. In step S6, it is determined whether or not the separating operation is “skip”. If “YES”, the reproducing operation is skipped,
Move to step S11. If the determination is “NO”, in step S7, the (i-th)
1) The “compressed identifier” field in the row is compared with the “compressed identifier” field in the i-th row, and if they are the same, that is, if “YES” is determined, the process proceeds to step 9. If it is different, that is, if “NO”, the contents of the “compression identifier” column and the “file name” column of the i-th line are read in step S8. The playback mode switching unit 9 sets the playback driver corresponding to the compression identifier to a state in which the playback of the moving image data specified by the file name can be started.
01 connects the virtual screen to the video display unit 410 for display. In step S9, the value of the “separation position” on the i-th line is read as the start point of the playback section, and the value of the “separation position” on the (i + 1) -th line is read as the end point of the playback section. On the other hand, reproduction from the start point to the end point is started. At the time when the reproduction is completed, it is determined in step S10 whether or not the reproduction has been performed a predetermined number of times specified in the "auxiliary information 1" of the i-th row. And return to "Y
If "ES" is determined, in step S11, the row number i is set to i = i + 1, and the process returns to step S2.

Here, the reproduction operation of the fifth and sixth lines of the edit table 201 will be described.

In step S2, one line of the fifth line is read. Since row data actually exists, the end determination of step S3 is "NO", and the process proceeds to step S4. Since the special effect is specified, the program A in the “special effect” column is started using the content of the parameter X in the “auxiliary information 2” column as a parameter. When the execution of the program is completed, the “separation operation” is read in step S5. In step S6,
It is determined whether or not the delimiter operation is skipped, and since it is "slow", it is determined as "NO". In step S7, it is determined whether or not the compression identifier is the same as the fourth line. Since both are the same MPEG1, it is determined as "YES". Proceed to step S9. In step S9, the break position (00: 45: 00: 0) of the fifth line is set as the start point of the playback section, and the break position (00: 50: 05: 0) of the sixth line is set as the end point of the play section.
0), and causes the moving image data reproducing unit 2 to start reproduction from the start point to the end point. When the reproduction is completed, it is determined in step S10 whether or not the reproduction has been performed a specified number of times. Since there is no repetition designation in the column of "auxiliary information 1" on the fifth line, it is determined that the reproduction has been performed the specified number of times, and "YES" is determined.
And returns to step S2. In step S2, the sixth line of the edit table is read, and in step S3
To determine the end, and to determine in step S4 whether there is a special effect.
If both are “NO”, the process proceeds to step S5 to read the separating operation. In step S6, whether or not it is "skip"
Judge "YES", proceed to S11, add 1 to i,
It returns to step S2.

Next, the reproduction operation of the seventh and eighth lines of the edit table 201 will be described.

In step S2, one line of the seventh line is read. Since row data actually exists, the end determination of step S3 is "NO", and the process proceeds to step S4. Since the illustration is designated by the special effect, the second illustration in the illustration list is displayed for 2 seconds based on the parameter data in the column of "auxiliary information 2". After the illustration is displayed, the separating operation is read in step S5. Since it is "play", the determination in step S6 is "NO", and the compression identifiers are compared in step S7. Since the compression identifier on the sixth line is MPEG1, and on the seventh line is MPEG2, the compression identifier is different, so that "NO" is determined, and the process moves to step S8. In step S8, an initialization process is performed on the MPEG2 playback driver 802b in the read / playback mode switching unit 9 to read the compression identifier "MPEG2" so that the moving image file name "H10th year sports day. DV" can be played back. It should be noted that the reproduction initialization processing of each moving image data, such as the above-described reproduction initialization processing, is performed on all the moving image files in advance before the reproduction processing on the first row of the edit table 201 starts, or is made to correspond to the reproduction order. Thus, the initialization process may be performed in parallel during the reproduction of other data before the reproduction starts. After that, the virtual screen 803 b is displayed by the display switching unit 801 on the video display unit 410.
Switch to correspond to. Next, in step S9, the break position (00: 10: 45: 15) of the seventh line of the edit table 201 is set as the start point of the playback section, and the break position of the eighth line (00: 15: 00: 10) is set. , The normal reproduction corresponding to the break operation “play” on the seventh line is executed. After the reproduction is completed, in step S10,
Since repetitive reproduction is not specified in the auxiliary information 1 on the seventh line, "YES" is determined, and i is determined in step S11.
And returns to step S2. In step S2,
The eighth line of the edit table 201 is read. Since the row data exists, the processing is not completed, and the step S3 is "N
"O" is determined, and no special effect is specified in step S4, so that the process is skipped. In step S5, the separating operation is read. Since the separating operation is "skip", step S6 is performed.
Is determined as "YES", the process jumps to step S11, adds 1 to i, and returns to step S2.

Next, the thirteenth of the edit table 201
The reproduction operation on the 14th, 15th, and 15th lines will be described.

In step S2, the edit table 20
The data for one line in the 13th line of the first line is read. Since there is line data, it is not the end and step S3 is determined to be "NO", and no special effect has been specified, so step S4 is skipped, and the delimiter operation is read in step S5. S6 is determined as "NO", and the compression identifier is "DV", which is the same as the twelfth line of the edit table 201 in step S7, so that step S7 is determined as "YES". Step S9
Then, the first point of the edit table 201 is set at the start point of the playback section.
A break position (00: 10: 00: 00) of the third line is set, and a break position (00: 12: 1) of the fourteenth line is set as the end point.
5:00) and normal playback is performed from the start point to the end point.
Since the auxiliary information 1 in the thirteenth row does not have a repeat reproduction designation, "YES" is determined in the step S10, and
At 11, 1 is added to i, and the process returns to step S2. In step S2, the 14th line of the edit table 201 is read for one line. Since row data exists, step S3 is determined as "NO", and the special effect is read in step S4.
Since “illustration” is designated as the special effect, the data of the auxiliary information 2 is read, and the third illustration in the illustration list is displayed for three seconds. When the display of the illustration is completed, the separation operation is read in step S5. Since the delimiting operation is “play”, “NO” is determined in the step S6,
In step S7, since the compression identifiers of the 13th and 14th lines of the edit table 201 are both "DV", step S7 is determined to be "YES". In step S9,
At the start point of the playback section, a break position (00: 12: 15: 00) on the 14th line of the edit table 201 is set,
At the end point, the break position on the 14th line (00:15:00:
00), and normal playback is performed up to the start point or the end point. After the reproduction is completed, the auxiliary information 1 on the 14th line does not have the reproduction specification repeatedly. Therefore, the determination in step S10 is "YES", 1 is added to i in step S11, and the process returns to step S2.
In step S2, the 15th line of the edit table 201 is read for one line. Since the row data exists, it is not the end, and step S3 is determined as "NO", and step S4
Since the special effect is not specified, the program skips the special effect and reads the delimiter operation in step S5. Since the delimiter operation is "skip", "YES" is determined in step S6, the process jumps to step S11, i is incremented by 1, and step S2 is performed. Return to Finally, in step S2, the 16th line of the edit table 201 is read. Since there is no line data, the end of the edit table is determined to be "YES" in step S3, the reproduction is stopped in step S12, and the edit reproduction process ends.

FIG. 3 shows a new edit table 301. Line 101 of edit table 301, 10
The second row is the edit table rearranging unit 14
Thus, the seventh and eighth lines of the edit table 201 are copied, and each "group identifier" is changed to "2". The 103rd and 104th lines of the edit table 301 are respectively edited by the edit table rearranging unit 14 by the edit table 201.
Are copied from the first line and the second line, and each "group identifier" is changed to "2". Further, the 105th and 106th lines of the edit table 301 are copied from the 11th and 12th lines of the edit table 201 by the edit table reordering unit 14, respectively, and each "group identifier" is set to "2". ]. Now, when the edit reproduction unit 8 instructs the edit reproduction unit 8 to perform the edit reproduction for the item whose “group identifier” is indicated by “2”, the edit reproduction unit 8 reads the edit table 301 and reads the edit table 301 from the 101st line to the 106th line. Interpret the line data and execute edit playback. As a result, what is reproduced and displayed on the video display unit 410 selects an arbitrary one of each reproduction section and reproduction operation / special effect defined in the edit table 201,
In addition, the reproduction order is changed and displayed. As described above, for example, the edit data once defined in the edit table 201 is selected and rearranged by the edit table rearranging unit 14 to select and reorder the edit data, and the reproduction order is switched. The operation can be easily performed.

FIG. 9 illustrates the operation of the embodiment of the moving picture data reproducing section 2 according to the tenth and eleventh aspects. An operation for reproduction is performed by, for example, a rewind button 407 or a fast forward button 408. Reference numeral 901 denotes a normal fast-forward playback state. Since the fast-forward speed is constant, the playback time is proportional to the length of the playback section. 902 and 9
03 indicates the operation of the moving image data reproducing unit 2 according to the present invention.
902a is a variable speed reproduction section, and 902b is a constant speed reproduction section. In the variable speed playback section 902a, the playback speed is increased, for example, by a quadratic function or an exponential function. That is, for example, when the fast-forward button 408 is clicked once, the displayed image becomes 1
When the frame advances and the fast-forward button 408 is kept depressed, slow playback is initially performed, and the playback speed is gradually increased by a quadratic function or an exponential function to perform fast-forward playback. Thereafter, in the constant-speed playback section 902b, fast-forward playback at a constant playback speed is performed.
As an actual embodiment, only the variable speed reproduction section 902a or only the constant speed reproduction section 902b may be provided. When the rewind button 407 is pressed, the reproduction speed is set to a negative value, and the same operation is performed in the reverse direction. In the embodiment having only the constant-speed playback section 902b, when the playback is completed within a certain time, for example, assuming that the playback section length is NL1 and the designated playback time is Nx, if the playback speed is NL1 / Nx double speed, the playback of the designated playback section is performed. Regeneration can be completed in Nx hours.
Assuming that the designated playback time is Nx, 902 indicates an operation when the playback section length is NL1, and 903 indicates an operation when the playback section length is NL.
2 shows the operation in the case of 2. Further, in another embodiment, for example, the reproduction may be controlled so that the total reproduction time of the variable-speed reproduction section 902a and the constant-speed reproduction section 902b is exactly the specified reproduction time Nx. Section 902
At a, when the playback speed reaches NL1 / Nx, the playback speed of the constant speed playback section 902b may be set to NL1 / Nx double speed to perform the constant speed playback. In this case, the actual reproduction time slightly fluctuates with respect to Nx. Furthermore, when the playback section is 1
If a set of a plurality of sections spanning a plurality of moving image data recorded by one or a plurality of compression methods, and the length of each of the playback sections is NL1, NL2,. , (NL1 + NL2 +... + NL
i) / Nx.

Next, an embodiment using software playback for fast-forward / rewind playback will be described. Fast forward and rewind are realized by thinning out video frames.
Now, in the case of performing fast forward playback at Lx double speed, assuming that there is a capability of displaying frame-thinning display Ld times per second, a normal video is displayed at a rate of 30 frames per second, so thinning-out by one display is performed. The number Ls of frames is Ls = 3
It is represented by 0Lx / Ld. That is, if d is displayed for one second by thinning out each Ls frame, playback is performed at Lx double speed.

In the above-described embodiment of the moving image data reproducing section 2, the reproduction in the variable-speed reproduction section 902a is initially performed at a slow speed, and the reproduction speed is gradually increased by a quadratic function or an exponential function. For example, for example, the position information of a scene change of a video is held beforehand at the time of recording or processing after recording, and in a section where a scene change frequently occurs, the fast-forward speed is reduced, and the scene change is performed. In a small section, the fast-forward speed may be controlled such that the fast-forward speed is faster.
