ABSTRACT:
TECHNICAL FIELD
The present invention relates to an edited-list creating apparatus, an editing apparatus and an editing method, and is appropriately applied to an edited-list creating apparatus, an editing apparatus and an editing method capable of creating a so-called edited list in which the edit content is defined for obtaining a desired edited image and sound, for example, by linking a plurality of pre-registered image and sound materials (hereinafter, referred to as clips) together in a desired state.
BACKGROUND ART
Formerly, there has been proposed such an editing apparatus capable of displaying a predetermined GUI (Graphical User Interface) screen, in which a user can create the edited list by using the GUI screen.
In practice, the GUI screen displays identify information such as ID number of each clip pre-registered or titles, and in this state, a desired clip can be selected through the manipulation of a mouse.
Moreover, as shown in
FIG. 16A
, the GUI screen displays first and second tracks
91
A and
91
C for image, a track
91
B for video special-effect, first and second tracks
91
D and
91
E for sound, along the time axis
90
.
On the GUI screen, after a desired clip being selected, a desired position of the track
91
A,
91
C,
91
D or
91
E for image or sound is specified through the manipulation of the mouse and thereby, as shown in
FIG. 16B
, frames
92
A to
92
D having a length corresponding to the material length of the selected clip are displayed with the specified position as the front end, on the track
91
A,
91
C,
91
D or
91
E.
Thus, in such editing apparatus, the aforementioned operation is successively repeated on the GUI screen, and frames
92
A to
92
D of the desired clips are displayed successively on the first or second track
91
A,
91
C for image, and the first or second track
91
D,
91
E for sound so that the frames are continuous with each other on the time axis
90
, and thereby an edited list can be created.
However, in such a conventional editing apparatus, if the frame
92
A to
92
D of the desired clip is displayed on the track
91
A,
91
C,
91
D or
91
E, it is hard to previously recognize the length of the frame
92
A to
92
D. Therefore, since it is difficult to beforehand grasp the relations between the frame
92
A to
92
D and other frames previously displayed on the track
91
A,
91
C,
91
D or
91
E, there was a problem of difficulty in creating an edited list efficiently.
Besides, as such editing apparatus as mentioned above, there have in recent years been those in which the image and the sound of individual clips are linked or unlinked and registered while being linked or unlinked. In the editing apparatus of such a configuration, if the image and the sound of the clips are registered while being linked, the frame
92
C or
92
D is automatically displayed on the track
91
D or
91
E for sound corresponding to displaying of the frame
92
A or
92
B on the track
91
A or
91
C for image, and if the image and the sound of the clips are registered while being unlinked, the frame
92
A to
92
D is displayed only on the specified track
91
A,
91
C,
91
D,
91
E for image or sound.
Further, in this editing apparatus, when the position of the frame
92
A to
92
D displayed on the track
91
A,
91
C,
91
D,
91
E for image or sound is moved along the time axis
90
, moving one frame
92
A to
92
D displayed on the track
91
A,
91
C,
91
D,
91
E for image or sound enables a frame
92
A to
92
D displayed on the track
91
A,
91
C,
91
D,
91
E for image or sound integrally corresponding to the relevant frame to be also moved along the time axis
90
, in the case where the image and the sound are linked.
However, in an editing apparatus of such a configuration, when the frame
92
A to
92
D displayed on the track
91
A,
91
C,
91
D,
91
E for image or sound is moved, it is difficult to determine whether the image and the sound of the clip corresponding to the relevant frame are linked or unlinked to be registered. Therefore, there is a problem of difficulty in creating an edited list efficiently.
Further, in the conventional editing apparatus described above, based on the edited list created described above, edited image and sound corresponding to the edited list are produced by controlling a plurality of video tape recorders respectively at predetermined timings to successively play back the corresponding clips and by successively joining these clips together while subjecting them to the special-effect processing if necessary.
Meanwhile, in performing an editing processing of joining two clips together through the special effect processing, such former editing apparatus obtains edited image and sound by allowing one to perform a playback or record processing again after once stopping both the video tape recorder for playback and a video tape recorder for record and accomplishing a cue and rewind operation.
Moreover, the editing apparatus of this type performs a similar operation whenever joining clips together and therefore it has a problem at the time of editing such as joining a plurality of clips together in succession in that so much time is required for the cue and rewind operation of a video tape recorder as not to perform a real time processing, thereby resulting in a significant decrease in the operating efficiency of editing processing.
Moreover, for example, when it is desired to obtain such a special effect as picture-in-picture, the former editing apparatus, in the case where in such a list the edit time of a first clip CL
10
and that of a second clip CL
11
overlap on the time axis
90
(
FIG. 16A
) and that of the second clip CL
11
is within that of the first clip as shown in
FIG. 17A
(herein after, referred to as inclusion), is so constructed as to switch the edit processing object from the first clip CL
10
to the second clip CL
11
and thereafter switch over to the original first clip CL
10
again at the stage of completion of edit processing of the second clip CL
11
.
Consequently, for example, even if an edited list with a plurality of second continuous clips CL
11
A
to CL
11
D
to be edit-processed within the edit period of time for the first clip CL
10
is made up as shown in
FIG. 17B
, since the edit processing object is switched from the first clip CL
10
to the second clip CL
11
A
and thereafter it is returned to the original first clip CL
10
at the stage of completion of edit processing of the relevant second clip CL
11
A
as designated with the arrow “a” in
FIG. 17C
, the editing apparatus of this type has a problem of being incapable of executing such an edit as to switch over from one video to another in the filial screen with the one-time edit at the time of a special effect such as picture-in-picture.
Thus, formerly, to obtain such a special effect, the corresponding edited list is so arranged as to be created after the image for the filial screens of picture-in-picture is previously edited and brought into one material, and there is a problem of difficulty in efficiently performing an edit operation.
