[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Before describing the moving picture editing apparatus and the editing operation according to the present invention, the data structure of recorded moving picture information to be edited will be described with reference to the drawings. Since it is better, it will be described below.

FIG. 11 schematically shows a sequence of frame images constituting a recorded video source as a time-series array. Image data of a video source recorded on a magnetic tape is generally arranged in such a format. Physically, a magnetic disk or an optical disk is not necessarily recorded in such a time-series arrangement, but has a different data arrangement. In a disk-shaped recording medium, any recorded video data can be accessed at almost the same time, which is advantageous.

A "cut" is defined as a set of frame images shot from the start to the end of one shooting operation with a TV camera. The “scene” is composed of a set of a plurality of cuts obtained by photographing a certain photographing target. Multiple scenes can be further organized under a particular shooting theme. The video source can be organized as a hierarchical structure of information, such as a plurality of cuts, a scene that summarizes some cuts, and a moving image having a shooting theme (or title) that summarizes some scenes. Each cut or scene is assigned a specific number. Note that the number of layers in the hierarchical structure can be increased by hierarchically expanding the concept of a scene using subsets such as chapters.

FIG. 12 shows an example of a tree-like hierarchical structure of a recorded video source. The shooting theme is “Tropical Island”. The recorded video sources included Cut 1, which shot fish in the sea around the island, Cut 2, which shot coastal scenery, Cut 3, which shot reptiles living in the forest, Cut 4, which shot flowers, and birds Cut 5, a shot 6 of a scene of a market, a cut 7 of a port, and the like. The cut 1 is composed of, for example, the first frame to the 90th frame, and the cut 2 is composed of the 91st frame to the first frame.
It is composed of 50 frames. The images of the cut 1 and the cut 2 are put together as a scene 1 in which the photographing target is a sea image. The cuts 3, 4, and 5 are put together as a scene 2 in which the shooting target is a video of a forest. The cuts 6 and 7 are put together as a scene 3 in which the shooting target is a town scenery.

In an editing apparatus according to an embodiment of the present invention, which will be described in detail later, a part or all of the hierarchical structure can be displayed on an editing screen. You can arbitrarily specify which part of the hierarchical structure to display. On the screen having the hierarchical structure, a representative frame image in the frame images constituting each of the cuts and a frame image of a representative cut in the cuts constituting the scene are displayed as reduced still images. Not only the reduced still image but also character information indicating the attribute of the reduced still image can be displayed on the screen for displaying the hierarchical structure.

In the embodiment of the present invention, editing can be easily performed by changing the original hierarchical structure on the screen by a simple operation of the operator. For example, the cut 1, the cut 3, and the cut 5 can be changed or edited into a hierarchical structure that is a lower hierarchy of a new scene 1 in which an animal that lives on an island is to be photographed. When the video whose hierarchical structure has been changed in this way is reproduced, the video edited in the order of cut 1, cut 3, and cut 5 can be seen. In the editing operation using the screen for displaying the hierarchical structure, it is possible to easily replace or delete cuts or add another cut. Furthermore, the order of the scenes can be easily changed. For example, scene 3, scene 1, scene 2
You can edit the order as shown. In that case, the order of the cuts in the lower hierarchy of the scene is also changed.

FIG. 1 shows a monitor screen 200 of a moving picture editing apparatus according to an embodiment of the present invention. In the screen, a window 201 is an editing window (editing area). In the editing area 201, cuts 210 to 214 and scenes 220 to 2 constituting a moving image of a video source to be edited are set.
21 representative images are displayed in reduced size. These reduced images are displayed in a tree-like hierarchical structure.

The editing window 201 further has an operation key area 240. The operation key area 240 has editing function key icons 241, 242, 243,... For designating various editing operations. Editing can be performed by moving the cursor to the edit function key area 240 by operating the mouse and designating a desired key icon. For example, when the key 241 for displaying the cut list is designated, the window 203 is displayed on the screen. In the cut list window 203, reduced still images 210 to 214... Representing each cut are displayed in chronological order.
When the key 242 for moving image reproduction is designated and a predetermined cut representative image 210 or scene representative image 220 is designated, the video of the cut is reproduced on the moving image window 202. The key 243 is a key for a bind function described later. There is also a key for replacing a cut screen or a scene screen having a hierarchical structure. Although many other editing function keys are provided, their description is omitted.

[0017]

Embodiments of the present invention will be described below. FIG. 2 is a block diagram of a configuration example of the moving image editing apparatus. That is, a CPU 101 for processing various controls, and a monitor 108 for displaying moving images, scenes used for editing, hierarchical structure (tree structure) information indicating cut and edit states, and the like.
And a memory 102 for storing various control programs of the CPU 101, a frame buffer 107 for storing an image to be displayed on a monitor 108, and detecting a change point of a cut by inputting a series of moving images including a plurality of cuts. And a cut change point detection unit 103 that performs the operation.

A series of moving images and a cut change point detecting unit 10
The moving image related information having the frame number describing the change point detected in Step 3 and the image file name for reduced display and the entire moving image or scene including the plurality of frame images can be processed at high speed without performing expansion processing described later. A reduced display image reduced to fit the size displayed as a representative image for display and viewing, a hierarchy number indicating the number of levels in each of a plurality of scenes or cuts, and a reduced display image A monitor 108 that displays a file name, a cut number serially assigned from the first cut, and a hierarchical structure for each cut including a plurality of frames.
And a magnetic storage device 106 for storing hierarchical structure management information including an identifier indicating whether or not to display the information.

Further, a video interface 104 for inputting a video signal from the VTR 105 and converting the video signal into a format for handling moving images by this apparatus, a mouse or keyboard 109 as input means, and an image input from the VTR 105 via the interface 104 An image compression unit 112 is provided to generate compressed image data by compressing information and to expand the compressed image data to reproduce image information.

The CPU 101, the memory 102, the cut change point detection unit 103, the video interface 104, the magnetic storage device 106, the frame buffer 107, and the image compression unit 112 are connected to a bus 110.
Controlled by access from Magnetic storage device 106
Alternatively, another storage medium may be used, or a remote file via a network (for example, a network using a LAN or an RS-232C interface) may be used.

With the above-described apparatus, moving image information can be stored and managed in a hierarchical structure, necessary scenes and cuts can be easily searched, and editing in units of scenes and cuts can be facilitated. In addition, the division of the cut unit can be automatically performed, and the burden on the user can be eliminated.

Next, the operation in such a configuration will be described. First, an instruction to register the moving image information read from the video tape set in the VTR 105 and compressed by the image compression unit 112 in the magnetic storage device 106 is issued by the instruction of the mouse or the keyboard 109. Then, along with the registration operation, the moving image information is supplied from the VTR 105 to the cut change point detection unit 103 via the video interface 104 and the bus 110. The cut change point detection unit 103, for example, encodes the input moving image information, and then detects a change point of the cut in the moving image information.

When the cut change point is determined and the break of the cut is determined, the moving image related information file corresponding to each cut divided according to the cut change point as shown in FIG. Is created and stored. The cut number slot 301 of the moving image related information file holds the cut number of the cut, and the cut length slot 302 holds a value corresponding to the number of frames included in the cut. The file name slot 303 holds a substantially unique cut name corresponding to the cut, and the frame number slot 304 holds, for example, the frame number of the first frame image of the cut. At this time, in order to view the entire moving image or a scene including a plurality of frames at a high speed, the reduced display image is magnetically stored as a high-speed display image as a high-speed display image and an image reduced to a size displayed as a representative image. Stored in device 106.

In general, in order to extract a predetermined frame image from encoded and compressed moving image information, it is necessary to decode and decompress the frame image, and the processing time of the CPU 101 is required. However, if the moving image information, which is image information reduced in advance for high-speed display and not encoded as in this embodiment, is stored, the image can be read out without the processing time required for decoding. Can be.

The operator instructs the reading of the moving image registered in the magnetic recording device 106 by using the mouse or the keyboard 109. Then, the CPU 101 reads out only the first frame of each cut as a change point of the cut of the corresponding moving image, and displays the cut list window 203 of the screen 200 displayed on the monitor 108 as shown in FIG. In response to this display, the operator determines whether the change point of the cut is correct. The operator further instructs cut breaks or changes cut breaks using the mouse or keyboard 109.

The CPU 101 assigns a cut number to each of the cuts divided by the change point of the moving image stored in the magnetic recording device 106. Further, when it is instructed that the change point of the cut is not correct, the CPU 101 registers the moving image information of the magnetic storage device 106 again.

When the operator instructs moving image editing or the like with the mouse or keyboard 109, the corresponding hierarchical structure management information is read from the magnetic recording device 106 or the memory 102, edited on the screen, and editing is completed. The hierarchical structure is re-registered in the magnetic storage device 106.

The process of editing a moving image using the hierarchical structure will be described below with reference to FIGS. 6, 7, and 8. FIGS. 6, 7 and 8 show only the screen of the window 201 of FIG.

For example, reduced still moving images 801 and 802 respectively corresponding to moving image information (cut 1, cut 2, cut 3,..., Cut n,..., Cut j,...) Stored in the magnetic recording device 106. , 803, 804, 805, etc. are displayed side by side in the material area 203 in the stored order as shown in FIG. Before the start of editing, the reduced still image is not displayed in the editing area 201.

When the editing is started, for example, the operator selects the reduced still image 804 of the cut n and the reduced still image 805 of the cut j displayed in the material area 203 with the mouse or the keyboard 109, and these are selected. When the "combine" key 810 is selected and clicked in the case of, as shown in FIG. 6, the reduced still images corresponding to the cut n and the cut j are displayed in the editing area 201 where the reduced image was not displayed before the start of the editing. Images 804 ', 80
5 'is newly displayed. Furthermore, cut n and cut j
Are displayed together with the reduced still image 806 corresponding to the scene (scene k) constituted by the above, and the connections indicating the related state of the three reduced still images 804 ′, 805 ′, 806 are displayed. A figure representing a tree structure can be quickly displayed with simple operability.

At this time, as shown in FIG. 5, a hierarchical structure management information file including an image management information file, a scene management information file, and a cut image information file corresponding to the newly displayed tree structure display is displayed. Generated. In this case, among the slots in the scene management information file, the layer number slot 321 holds the number of the layer where the scene k is located, for example, “1”, and the scene number slot 322 stores the scene number corresponding to the scene k, for example, “K” is held and parent video number 1 slot 32
3 stores a moving image number corresponding to the moving image located at a higher hierarchical level of the scene k, and a child cut number 1 slot 324 stores the scene k
For example, a cut number “n” corresponding to a cut n, which is one of the child cuts located at a lower hierarchical level of “n”, is held. Similarly, the child cut number 2 slot 325 holds a child cut located at a lower hierarchical level of the scene k, for example, a cut number “j” corresponding to the cut j.

In this case, since the number of cuts located in the lower hierarchy of the scene k is 2, the cut number 3 serving as a child is empty because no data is held in the slot 326. further,
The icon display coordinate slot 327 includes the editing area 20
1, the coordinate information for determining the display position of the reduced still image 806 corresponding to the scene k is held, and the display identifier slot 328 displays the reduced still image 806 in the editing area 201. For example, information for identifying whether or not “display” is held.

Further, as the cut image information files in the hierarchical structure management information file, cut image information files corresponding to cut n and cut j are generated. Among them, among the slots of the cut image information file corresponding to the cut n, the layer number slot 331 holds the number of the layer in which the cut n is located, for example, “2”, and the cut number slot 301 ′ corresponds to the cut n. The cut number to be cut, for example, “n” is held, and a value corresponding to the number of frames of the cut n is held in the cut length slot 302 ′. Further, a substantially unique file name corresponding to the content of the cut n is held in the reduced display file name slot 303 ', and the frame number of the cut n, for example, the first frame image is held in the frame number slot 304'. You. Further, the icon display coordinate slot 33
2 holds coordinate information for determining the display position of the reduced still image 804 ′ corresponding to the cut n corresponding to the editing area 201. The display identifier slot 333 stores the reduced still image 804 ′ in the editing area 201. Information for identifying whether or not to display is held, for example, information of "display".

Although predetermined information is held in some of the slots of the cut image information file corresponding to the cut j different from the above, the description is omitted here.

Further, a moving image composed of a plurality of scenes displayed in the editing area 201, for example, a moving image 1, is created as an upper layer of each scene, and a reduced still image corresponding to the moving image 1 corresponds to each scene. And is connected to the reduced still image to be displayed. FIG. 7 shows the state of the tree structure. According to the hierarchical structure display, FIG.
A hierarchical structure management information file as shown in FIG. Among the slots in the image management information file of the hierarchical structure management information file, the layer number slot 311 holds the number of the layer where the moving image 1 is located, for example, “1”.

At this time, scene 1 in the lower hierarchy of moving image 1
In the layer number slot of the scene management information file corresponding to each of the scene 2 and the scene 3, the value is changed to a value which is a layer number indicating a lower layer immediately below the moving image 1 and held, for example, “2”. Is held. The moving image number of the moving image 1 is held in the moving image number 1 slot as a parent corresponding to each of the scene 1, the scene 2, and the scene 3, and for example, “1” is held. At this time, the layer number slot of the cut management information file corresponding to each of cut 1, cut 2, cut 3, cut 4, and cut 5 of the lower layer of each of scene 1, scene 2, and scene 3 further includes the above scene 1, is changed to a value that is a layer number indicating a lower layer immediately below each of the scenes 2 and 3, and is held, for example, “3” is held.

Further, of the slots in the image management information file, the moving image number slot 312 holds a moving image number corresponding to the moving image 1, for example, “1”. Further, the child scene number 1 slot 313 holds, for example, a scene number “1” corresponding to scene 1, which is one of the child scenes located in the lower hierarchy of the moving image 1. Similarly, the child scene number 2 slot 314 holds a child scene located at a lower layer of the moving image 1, for example, a scene number “2” corresponding to scene 2, and a child scene number 3 slot 315. Holds a child scene located at a lower hierarchical level of the moving image 1, for example, a scene number “3” corresponding to the scene 3. Further, the icon display coordinate slot 316 holds coordinate information for determining the display position of the reduced moving image 601 corresponding to the moving image 1 corresponding to the editing area 201, and the display identifier slot 317 stores the reduced still image 601. Information for identifying whether or not to display in the editing area 201, for example, information of “display” is held. As described above, a plurality of reduced still images corresponding to moving images, scenes, and cuts of each layer are displayed in the editing area 201 as shown in FIG. However, since the displayable size of the editing area 201 is restricted, it is conceivable to display only the cuts in the lower hierarchy of the selected scene. In the present invention, the cut is performed by operating as described below. Selection display switching is realized.

That is, the operator selects one of the reduced still images corresponding to each scene displayed in the editing area by using the mouse or the keyboard 109. When the “display” key 811 is selected and clicked while the selected still image is in the selected state, the cut still image displayed in the editing area 201 is cut in the lower hierarchy of the selected scene. Is displayed as it is, and the reduced still image corresponding to the cut located in the lower hierarchy of the scene other than the scene in which the reduced still image is selected is not displayed.

The setting of display or non-display of the reduced still image is switched by the display identifier slot 33 of each cut image information file corresponding to the cut not to be displayed in the hierarchical structure management information file described above.
This is performed by rewriting the information held in No. 3 from “display” to “not display”.

As a specific example, an operation in the case where the cuts below scene 1 in FIG. 7 are displayed and the scenes other than scene 1, for example, the cuts below scene 2 and scene 3 are not displayed will be described.

The operator converts a reduced still image 601 corresponding to scene 1 displayed in the editing area 201 of FIG.
Select with the mouse or keyboard 109. When the “display” key 811 is selected and clicked while it is in the selected state, the reduced still image displayed in the editing area 201 as shown in FIG. 1, the reduced still images corresponding to scenes 2 and 3 are still displayed, and similarly, the reduced still images corresponding to cuts 1, 2 and 3 located in the lower hierarchy of scene 1 are still displayed. Becomes Other reduced still images corresponding to cuts 4, 5, and 6 displayed in FIG. 7 are not displayed in FIG.

In this case, using the hierarchical structure management information file, scene management information files of scenes other than the selected scene, that is, scenes other than scene 1 are sequentially referred to. For example, the information held in the child cut number 1 slot 324 and the child cut number 2 slot 325 in the scene management information file of scene 2, that is, the cut numbers of cut 4 and cut 5 are respectively read. . Then, based on the cut numbers held and read in the respective slots, the cut image information file of the lower layer cut of scene 2 is referred to, and the cut 4
And the value of the display identifier slot of the cut image information file corresponding to the cut and the cut image information file corresponding to the cut 5 are set to “not display”. Similarly, the same processing as described above is performed for the scene management information file of scene 3.

In the above description, the tree hierarchical structure is described as a three-layer structure. However, even when the number of layers is larger than three, if the value of the display identifier slot of the lower hierarchy is set by the same operation, the desired structure is obtained. Of multiple levels of reduced still images,
It is possible to display only reduced still images that are equal to or smaller than the selected reduced still image.

Further, the displayed position of the displayed reduced still image can be changed. The procedure for the change will be described below. The display position of the reduced still image is changed by changing the icon display coordinate slot of each scene management information file or cut image information file corresponding to the scene or cut whose display position is to be changed in the hierarchical structure management information file described above. This is performed by rewriting the held information to a predetermined coordinate information value.

As a specific example, FIG.
The operation when the reduced still images corresponding to the cuts of scene 1 and below are displayed and the reduced still images corresponding to the cuts of scenes 2 and 3 and below are not displayed will be described.

The operator converts the reduced still image 601 corresponding to scene 1 displayed in the editing area 201 of FIG.
Select with the mouse or keyboard 109. When the “display” key 811 is selected and clicked while it is in the selected state, the reduced still image displayed in the editing area 201 as shown in FIG. 1, the reduced still images corresponding to the scenes 2 and 3 are still displayed, and the display position is changed. For example, the display interval between the reduced still images corresponding to the scenes 1, 2 and 3 is increased. Shortened. Also,
Cut 1, cut 2, cut 3... Located at the lower hierarchy of scene 1 are displayed as reduced still images corresponding to cut i, and the display position is changed as necessary.

In this case, using the hierarchical structure management information file, the scene management information file of the scene where the display position of the corresponding reduced still image is changed, and the cut of the cut where the display position of the corresponding reduced still image is changed The image information file is referenced. Then, for example, the value of the icon display coordinate slot in the scene management information file of scene 2 is set to a value at which the display position between the reduced still images corresponding to scene 1 and scene 2 becomes shorter. Similarly, the same processing as described above is performed for the value of the icon display coordinate slot related to another scene or cut. FIGS. 9 and 10 show processing flowcharts when displaying only a part of the hierarchical structure specified by the operator.
Shown in In step 701, a reduced still image corresponding to a scene is selected. In step 702, a “display” key 811 in the icon 240 is clicked. Step 703
Then, an image management information file ((A) in FIG. 5) corresponding to a moving image of a higher layer of a scene (selected scene) corresponding to the selected reduced still image is accessed. Step 7
At 04, a "child scene number" corresponding to a scene other than the selected scene in the file is referred to. Step 705
It is determined whether or not the slot of the “child scene number” in the image management information file is empty. If the slot is empty, the process ends at step 706. If the slot is not empty, in step 707, the scene management information file ((B) in FIG. 5) of the scene corresponding to the data content of the "child scene number" is accessed. At step 708, the first slot of the child cut number in the scene management information file is selected. In step 709, a cut image information file ((C) in FIG. 5) of the cut corresponding to the data content of the slot of “child cut number” is accessed. At step 710, the data content of the slot of the display identifier is set to "not display". In step 711, it is determined whether the second slot of the “cut number to be a child” in the scene management information file ((B) of FIG. 5) is empty.
If not empty, return to step 709. If it is empty, it is determined in step 712 whether the second slot of the “child scene number” in the image management information file ((A) of FIG. 5) is empty. If it is empty, the process ends, and if it is not empty, the process returns to step 707.

In the above description, instead of displaying the reduced still images corresponding to the respective moving images, scenes, and cuts,
It is also possible to arbitrarily switch the display of the reduced moving image corresponding to each moving image, scene, and cut.

[0049]

As described above, according to the present invention,
When scenes and cuts constituting a moving image (moving image) are displayed according to the hierarchical structure, scenes and cuts below a predetermined layer are selected without scrolling all representative images of the entire hierarchical structure. By displaying only scenes or cuts belonging to scenes of the hierarchy or lower, it is possible to quickly grasp the edited video content.
