Description

  The present invention relates to a computer-aided moving image editing method, a moving image editing apparatus, and a recording medium for recording a procedure related to the moving image editing method, which are used when moving images are produced such as television broadcast program production and video program production.

  In facilities used for television broadcast program production and video program production, the use of computers is rapidly increasing in functionality. Especially in recent years, video tape recorders are stored in large-capacity random access storage devices such as hard disks that are inexpensive and easy to handle and save, instead of video editing methods that repeat fast forward and rewind, relying on a tape counter. There is a moving image editing apparatus that edits stored image information with the assistance of a computer.

  Japanese Patent Application Publication No. JP-A-4-207877 discloses a moving image management apparatus for editing moving images in scenes or cut units. In this device, the hierarchical structure of cuts and scenes is displayed on the screen in the form of a tree structure.

However, if a large number of cuts are edited using a tree structure (hierarchical structure), the entire editing state cannot be displayed due to the limitation on the resolution of the monitor screen. In that case, the user has to confirm by scrolling the display content, and there is a disadvantage that the operation becomes complicated and the content is difficult to grasp.
JP-A-4-207877

  As described above, the present invention stores, manages, and displays a moving image in a tree structure (hierarchical structure) of many scenes and cuts in order to easily find a necessary scene and cut. When the user confirms the entire editing state, the disadvantage that the user has to confirm the scroll bar of the window displaying the tree structure with the mouse is eliminated or reduced.

  In the moving image editing method of the present invention, in a moving image editing apparatus that edits a moving image composed of a plurality of frame images on an editing screen, a cut image and a representative image of a scene image constituting the frame image are arranged in a hierarchical structure, An identifier indicating whether or not to display a cut image and a scene image is added to the management information, and a hierarchical structure is displayed according to the identifier.

  Further, the moving image editing apparatus of the present invention is a moving image editing apparatus that edits a moving image composed of a plurality of frame images on an editing screen, and has a hierarchical structure for cut images constituting a frame image and representative images of scene images. A hierarchical structure managing means for managing hierarchical information of the hierarchical structure, a means for adding an identifier indicating whether or not to display a cut image and a scene image to the hierarchical structure managing means, and a means for displaying the hierarchical structure according to the identifier Having.

  According to the present invention, a method for editing an image with computer assistance while viewing moving image information displayed on a screen includes a step of selecting a plurality of reduced still images representing a video scene or a video cut constituting the moving image information; A step of determining a hierarchical structure between still images, a step of specifying a still image related to a predetermined hierarchical structure portion of the hierarchical structure, and a hierarchical portion including the specified still image so as to represent the hierarchical structure Displayed on the screen in a simple arrangement.

  According to the present invention, a recording medium for storing a program code read and executed by a computer has a hierarchical structure between the still images according to selection of a still image representing a video scene or a video cut constituting moving image information. A first code section representing a procedure of determining the procedure, and a still image related to a predetermined hierarchical structure portion of the hierarchical structure is designated, and the hierarchical portion including the designated still image is And a second code section representing a procedure of a procedure to be displayed on the screen in an array representing the above.

  A moving image editing apparatus that edits an image with computer assistance while viewing moving image information displayed on a screen according to the present invention, a recording apparatus that records moving image information, for example, when recording a moving image on a recording apparatus By comparing adjacent frame images, and when information changes between adjacent frame images exceeding a predetermined amount, the adjacent frame images are recognized as frame images belonging to different cuts. A change point detection unit for detecting a change point of the image, a reduced still image obtained by thinning out the data amount of the frame image constituting each cut, and information for the reduced still image to be an image representing each cut In other words, a recording device that records a reduced display file, and a plurality of arbitrary cuts are grouped as a scene to generate information for identifying a scene, and a plurality of predetermined scenes are animated In this way, information for identifying a moving image is collectively generated, and according to selection of a reduced still image that represents a video scene or a video cut constituting moving image information, a video scene represented by a reduced still image and a video cut A control unit that determines a hierarchical structure, a designation unit that designates a reduced still image related to a predetermined hierarchical structure portion of the hierarchical structure, and an array in which the hierarchical portion including the designated reduced still image represents the hierarchical structure Including the display to represent.

  According to the present invention, when scenes and cuts constituting a moving image (moving image) are displayed according to a hierarchical structure, scenes and cuts below a predetermined hierarchy are displayed without scrolling all the representative images of the entire hierarchical structure. With regard to, by displaying only scenes or cuts that belong to the selected scene or lower of the hierarchy, it is possible to quickly grasp the edited video content.

  Before the description of the moving image editing apparatus and the editing operation according to the present invention, it is better to explain the data structure of the recorded moving image information to be edited with reference to the drawings. .

  FIG. 11 is a schematic representation of a frame image sequence constituting a recorded video source as a time-series arrangement. Image source image data recorded on the magnetic tape is generally arranged in this format. In a magnetic disk or an optical disk, physically, it is not always recorded in such a time-series arrangement, and another data arrangement is obtained. A disc-shaped recording medium is advantageous because any recorded video data can be accessed in almost the same time.

  “Cut” is defined as a set of frame images shot from the start to the end of one shooting operation with the TV camera. A “scene” is composed of a set of a plurality of cuts obtained by shooting a certain shooting target. Multiple scenes can be further grouped under a specific shooting theme. Video sources can be organized as a hierarchical structure of information, such as a plurality of cuts, a scene that combines several cuts, and a moving image that has a shooting theme (or title) that combines several scenes. Each cut or scene is assigned a specific number. Note that the number of layers in the hierarchical structure can be increased by expanding the concept of the scene hierarchically using a subset such as a chapter.

  FIG. 12 shows an example of a tree-like hierarchical structure of recorded video sources. The shooting theme is “Tropical Island”. Recorded video sources include cut 1 taken from underwater fish around the island, cut 2 taken from coastal scenery, cut 3 taken from reptiles living in the forest, cut 4 taken from flowers, and birds taken The cut 5 which photographed the scenery of the market, the cut 6 which photographed the scenery of the market, the cut 7 which photographed the harbor, etc. are included. 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 150th frame. The images of cut 1 and cut 2 are collected as scene 1 in which the subject is a sea image. Cuts 3, 4, and 5 are summarized as scene 2 in which the subject of shooting is a forest image. Cuts 6 and 7 are summarized as scene 3 whose shooting target is a town landscape.

  In the editing apparatus according to the embodiment of the present invention described in detail later, a part or all of this hierarchical structure can be displayed on the editing screen. You can specify which part of the hierarchical structure to display. On the screen having a hierarchical structure, a representative frame image in a frame image constituting each of these cuts and a frame image of a representative cut in a cut constituting a scene are respectively displayed as reduced still images. Not only the reduced still image but also the 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, it is possible to change, that is, edit, a hierarchical structure in which cut 1, cut 3, and cut 5 are lower layers of a new scene 1 in which animals living on an island are photographed. If the video with the hierarchical structure changed is reproduced in this way, the video edited in the order of cut 1, cut 3, and cut 5 can be seen. In an editing operation using a screen for displaying a hierarchical structure, it is possible to easily replace and delete cuts or add another cut. Furthermore, the order of scenes can be easily changed. For example, editing can be performed in the order of scene 3, scene 1, and scene 2. 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 image 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, representative images of the cuts 210 to 214 and the scenes 220 to 221 constituting the moving image of the video source to be edited are displayed in a 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 operating the mouse to move the cursor to the editing function key area 240 and designating a desired key icon. For example, when the cut list display key 241 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 a moving image reproduction key 242 is designated and a predetermined cut representative image 210 or scene representative image 220 is designated, the cut video is reproduced on the moving image window 202. A key 243 is a key for a bind function described later. There is also a key to replace the hierarchical cut screen and scene screen. Many other editing function keys are provided, but their description is omitted.

  Examples 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 that processes various controls, a monitor 108 that displays information such as moving images, scenes used for editing, cuts, and a hierarchical structure (tree structure) representing editing states, and a memory that stores various control programs of the CPU 101 102, a frame buffer 107 that stores an image to be displayed on the monitor 108, and a cut change point detection unit 103 that detects a cut change point by inputting a series of moving images including a plurality of cuts.

  A series of moving images, moving image related information having a frame number describing a change point detected by the cut change point detection unit 103 and an image file name for reduced display, and an entire moving image or scene composed of the plurality of frame images. In order to display and display at a high speed without performing the expansion processing described later, and to reduce the size of the reduced display image to fit the size displayed as the representative image, and the number of stages in each of the multiple scenes or cuts Whether or not to display on the monitor 108 displaying the hierarchical structure, the cut number assigned serially from the first cut for each cut consisting of a plurality of frames A magnetic storage device 106 that stores hierarchical structure management information including identifiers is provided.

  Furthermore, a video interface 104 for inputting a video signal from the VTR 105 and converting it into a format for handling a moving image by this apparatus, a mouse or keyboard 109 as an input means, and image information input from the VTR 105 via the interface 104 are compressed. An image compression unit 112 that generates compressed image data and decompresses 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 the bus 110 and are controlled by access from the CPU 101. Instead of the magnetic storage device 106, another storage medium may be used, or a remote file via a network (for example, a network using a LAN or RS-232C interface) may be used.

  With the above device, moving image information can be stored and managed in a hierarchical structure, necessary scenes and cuts can be easily found, and editing in units of scenes and cuts can be facilitated. Further, 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 by the instruction of the mouse or the keyboard 109 and compressed by the image compression unit 112 in the magnetic storage device 106 is given. Then, along with the registration operation, 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 encodes the input moving image information, for example, and then detects a cut change point in the moving image information.

  When the cut change point is determined, and the cut delimiter is determined, the magnetic recording device 106 stores the data of the moving image related information file corresponding to each cut delimited according to the cut change point as shown in FIG. Created and stored. The cut number slot 301 of this 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, and is used for reduced display. 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 scene composed of a plurality of frames at a high speed, the reduced display image is magnetically stored as an image reduced in accordance with the size displayed as a high-speed display image and a representative image as a high-speed display image. It is stored in the 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 it, and the processing time of the CPU 101 for that purpose is required. However, if image information that has already been reduced for high-speed display as in the present embodiment and is not encoded is stored, the image can be read out without the processing time required for decoding. Can do.

  The operator instructs the reading of the moving image registered in the magnetic recording device 106 with 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 corresponding moving image cut, and displays a cut list window 203 on the screen 200 displayed on the monitor 108 as shown in FIG. In response to this display, the operator determines whether or not the cutting change point is correct. Further, the operator instructs the cut delimiter or changes the cut delimiter using the mouse or the keyboard 109.

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

  When the operator instructs to edit a moving image with the mouse or the 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 the edited hierarchical structure is displayed. Re-register in the magnetic storage device 106.

A process of editing a moving image using a hierarchical structure will be described below with reference to FIGS. 6, 7 and 8 show only the screen of the window 201 of FIG.
For example, the reduced still image corresponding to each of the moving image information (cut 1, cut 2, cut 3,..., Cut n,..., Cut j,...) Stored in the magnetic recording device 106. 801, 802, 803, 804, 805, etc. are displayed side by side in the material area 203 as shown in FIG. Note that before the start of editing, a reduced still image is not displayed in the editing area 201.

  When editing is started, for example, the operator selects a reduced still image 804 of cut n and a reduced still image 805 of cut j displayed in the material area 203 with the mouse or the keyboard 109, and these are in a selected state. When the “join” key 810 is selected and clicked, the reduced still image 804 ′ corresponding to each of the cut n and the cut j is displayed in the editing area 201 where the reduced image was not displayed until the editing started, as shown in FIG. , 805 ′ are newly displayed. Further, a reduced still image 806 corresponding to the scene (scene k) composed of the cut n and the cut j is displayed, and the related states of the three reduced still images 804 ′, 805 ′, and 806 are represented. Connections are displayed and graphics representing these tree structures can be quickly displayed with simple operability.

  At this time, a hierarchical structure management information file composed of an image management information file, a scene management information file, and a cut image information file as shown in FIG. 5 corresponding to the newly displayed tree structure display is generated. . In this case, among the slots of the scene management information file, the hierarchy number slot 321 holds the number of the hierarchy where the scene k is located, for example, “1”, and the scene number slot 322 holds the scene number corresponding to the scene k, for example, If “k” is held and the parent movie number 1 slot 323 has a parent movie registered in the upper hierarchy of the scene k, the movie number corresponding to the movie is held and becomes a child. The cut number 1 slot 324 holds a cut number “n” corresponding to, for example, the cut n, which is one of the child cuts located in the lower hierarchy of the scene k. Similarly, a child cut number 2 slot 325 holds a cut number “j” corresponding to a child cut located in the lower hierarchy of the scene k, for example, the cut j.

  In this case, since the number of cuts located in the lower hierarchy of the scene k is 2, no data is held in the child cut number 3 slot 326 and is empty. Further, the icon display coordinate slot 327 holds coordinate information for determining the display position of the reduced still image 806 corresponding to the scene k, which is a display position corresponding to the editing area 201, and the display identifier slot 328. Information for identifying whether to display the reduced still image 806 in the editing area 201, for example, “display” information is held.

  Further, cut image information files corresponding to cut n and cut j are generated as cut image information files in the hierarchical structure management information file. Among the slots of the cut image information file corresponding to the cut n, the layer number slot 331 holds the layer number where the cut n is located, for example, “2”, and the cut number slot 301 ′ corresponds to the cut n. A cut number, 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, the reduced display file name slot 303 ′ holds a substantially unique file name corresponding to the contents of the cut n, and the frame number slot 304 ′ holds the frame number of the first frame image of the cut n, for example. The Further, the icon display coordinate slot 332 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, and the display identifier slot 333 stores the reduced still image 804. Information for identifying whether or not to display 'in the editing area 201 is, for example, information of “display”.

It should be noted that predetermined information is also held in some of the slots of the cut image information file corresponding to the cut j different from the above, but the description thereof is omitted here.
Furthermore, a moving image composed of a plurality of scenes displayed in the editing area 201, for example, moving image 1 is created as an upper layer of each of the scenes, and a reduced still image corresponding to the moving image 1 corresponds to a reduced still image corresponding to each scene. Connected with the image and displayed. The state of the tree structure is shown in FIG. In response to this hierarchical structure display, a hierarchical structure management information file as shown in FIG. 5 is generated. Of the slots in the image management information file of this hierarchical structure management information file, the hierarchy number slot 311 holds the number of the hierarchy in which the moving image 1 is located, for example, “1”.

  At this time, the hierarchy number slot of the scene management information file corresponding to each of the scene 1, scene 2 and scene 3 in the lower hierarchy of the moving picture 1 is a hierarchy number indicating the lower hierarchy immediately below the moving picture 1. The value is changed and held, for example, “2” is held. The movie number 1 of the movie 1 is held in the movie number 1 slot which is a parent corresponding to each of the scene 1, the scene 2, and the scene 3, for example, “1” is held. At this time, the scene number 1 in the cut management information file corresponding to each of cut 1, cut 2, cut 3, cut 4 and cut 5 in the lower hierarchy of scene 1, scene 2 and scene 3 is also included in the above scene. Changed to a value that is a hierarchy number indicating that it is a lower hierarchy immediately below each of scenes 1, 2, and 3, for example, “3” is held.

  Further, among 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”. Furthermore, a child scene number 1 slot 313 holds a scene number “1” corresponding to scene 1, for example, which is one of the child scenes located in the lower hierarchy of the moving image 1. Similarly, a child scene number 2 slot 314 holds a child scene located in the lower hierarchy of the moving image 1, for example, the scene number “2” corresponding to the scene 2, and the child scene number 3 slot 315 stores the child scene number 2 slot 314. Holds a scene number “3” corresponding to a child scene located in the lower hierarchy of the moving image 1, for example, 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 to display in the editing area 201, for example, “display” information is held. As described above, a plurality of reduced still images corresponding to moving images, scenes, and cuts in each layer are displayed in the editing area 201 as shown in FIG. However, since the displayable size of the editing area 201 is limited, it is conceivable to display only the lower layer cut of the selected scene. In the present invention, the operation is performed 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 with the mouse or the keyboard 109. If the “Display” key 811 is selected and clicked when it is in the selected state, among the reduced still images displayed in the editing area 201, the cut is located in the lower hierarchy of the selected scene. The reduced still image corresponding to 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 where the reduced still image is selected is not displayed.

  The switching of the setting to display or not display the reduced still image is performed by changing the information held in the display identifier slot 333 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 done by rewriting the value from “display” to “not display”.

  As a specific example, a description will be given of an operation in a case where cuts of scene 1 or less in FIG. 7 are displayed and scenes other than scene 1, for example, cuts of scene 2 and scene 3 or less are not displayed.

  The operator selects the reduced still image 602 corresponding to the scene 1 displayed in the editing area 201 of FIG. If it is selected and clicked on the “Display” key 811 when it is in the selected state, as shown in FIG. 8, the reduced still image displayed in the editing area 201 is the moving image 1, the scene displayed in FIG. 1. Reduced still images corresponding to scene 1, scene 2, and scene 3 remain displayed. Similarly, reduced still images corresponding to cut 1, cut 2, and cut 3 located in the lower hierarchy of scene 1 remain displayed. It becomes. The other reduced still images corresponding to cut 4, cut 5, and cut 6 displayed in FIG. 7 are not displayed in FIG.

  In this case, using the hierarchical structure management information file, scenes other than the selected scene, that is, scene management information files of 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 the scene 2, that is, the cut numbers of the cut 4 and the cut 5 are read out. . Then, based on the cut number held and read in each slot, the cut image information file of the cut in the lower hierarchy of the scene 2 is referred to, and the cut image information file corresponding to the cut 4 and the cut 5 are corresponded. The value of each display identifier slot of the cut image information file is 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 there are more layers than three layers, if the value of the display identifier slot of the lower hierarchy is set by the same operation, a desired level can be obtained. Of the plurality of reduced still images, it is possible to display only a reduced still image that is less than or equal to the selected reduced still image.

  Furthermore, the display position of the reduced still image to be displayed can be changed. The change procedure will be described below. The display position of the reduced still image is changed in 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 done by rewriting the holding information with the value of predetermined coordinate information.

  As a specific example, similar to the above, a reduced still image corresponding to a cut of scene 1 or less in FIG. 7 is displayed, and a reduced still image corresponding to a cut other than scene 1, for example, scene 2 or scene 3 or less, is displayed. An operation when no image is displayed will be described.

  The operator selects the reduced still image 601 corresponding to the scene 1 displayed in the editing area 201 of FIG. If it is selected and clicked on the “Display” key 811 when it is in the selected state, as shown in FIG. 8, the reduced still image displayed in the editing area 201 is the moving image 1, the scene displayed in FIG. 1, the reduced still images corresponding to the scene 2, the scene 3 remain displayed, and the display position is changed. For example, the display interval between the reduced still images corresponding to the scene 1, the scene 2, and the scene 3 is increased. Shortened. In addition, a cut still image corresponding to cut 1, cut 2, cut 3... Cut i located in the lower hierarchy of scene 1 is displayed, 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 in which the display position of the corresponding reduced still image is changed, and the cut image information file of the cut in which the display position of the corresponding reduced still image is changed 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 that makes the display position between the reduced still images corresponding to scene 1 and scene 2 shorter. Similarly, the same processing as described above is performed for the icon display coordinate slot values related to other scenes or cuts. FIG. 9 and FIG. 10 show processing flowcharts when only a partial hierarchical structure designated by the operator is displayed. In step 701, a reduced still image corresponding to the scene is selected. In step 702, the “display” key 811 in the icon 240 is clicked. In step 703, an image management information file ((A) in FIG. 5) corresponding to the moving image of the upper hierarchy of the scene corresponding to the selected reduced still image (selected scene) is accessed. In step 704, a “child scene number” corresponding to a scene other than the selected scene in the file is referred to. In step 705, it is determined whether or not the “child scene number” slot 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) of FIG. 5) of the scene corresponding to the data content of “child scene number” is accessed. In step 708, the first slot of “child cut number” in the scene management information file is selected. In step 709, the cut image information file ((C) of FIG. 5) of the cut corresponding to the data content of the slot of “child cut number” is accessed. In step 710, the data content of the slot of the display identifier is set to “not display”. In step 711, it is determined whether or not the second “child cut number” slot in the scene management information file (FIG. 5B) is empty. If not empty, the process returns to step 709. If it is empty, it is determined in step 712 whether or not the second “child scene number” slot in the image management information file (FIG. 5A) is empty. If it is empty, the process ends. If it is not empty, the process returns to step 707.

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