Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video list which divides a video into scenes, expresses one scene by one icon, and displays the icons in a list so that an overview of the video can be quickly grasped. METHOD AND RECORDING MEDIUM CONTAINING A VIDEO LIST PROCESSING PROGRAM FOR IMPLEMENTING VIDEO LIST PROCESSING METHOD The present invention relates to a recording medium storing a video list processing program.

[0002]

2. Description of the Related Art Prior art 1 Switching of a scene from a video (called "shot switching").
Software products that detect and list
irage VideoLogger3.1 is developed and sold.
One of the objectives of such software products is to make information addition to video more efficient.

[0003] Referring to the schematic diagram of FIG.
An outline of the operation will be described.

An image 100 given as an input is composed of three scenes (shots) A, B, C, etc. In this example, a shot A is composed of four frames A1, A2, A3, A
4, and shot B has three frames B1, B2,
B3, and the shot C is composed of three frames C1, C
2, C3. These shots A, B,
The boundaries 101, 102, and 103 of C are called shot switching.

In the prior art 1, first, the shot switching position is detected. Various methods have been developed as a method for detecting a shot switching position using image processing. For example, the method can be detected by using a method disclosed in Japanese Patent No. 2869398, “Cut Point Detection Method and Apparatus”.

Subsequently, the first image of each shot is set as a representative image 201 (A1, B1, C1,.
A list is displayed in the representative image display window 200 by extracting it from 0 and reducing it.

As described above, in the prior art 1, the representative image is extracted from the shot and displayed in a list, so that the user can grasp the outline of the content without playing and viewing the video.

According to the prior art 1, an information adding interface can be constructed by using the representative image list created as described above. For example, when the user sets the representative image 2
When one of 01 is selected with a pointing device such as a mouse, a program is made so that a comment input window 203 is displayed.

Using the comment input window 203, additional information such as, for example, a character, a place, a date and time, an event, and the like is text-inputted for each shot. The input text is registered in the database and used later for searching. For example, when the word "Diet" is given, a scene (shot) relating to "Diet" is retrieved and displayed.

The first problem of the prior art 1 is that the shot change detection algorithm cannot detect shot change 100% correctly. For example, assume that a shot change indicating a boundary between shot A and shot B has not been detected. In this case, the representative image of the shot B is omitted from the representative image list, and an important shot may be missed. After all, in order to eliminate oversight, it is necessary to perform a complicated operation of reproducing and confirming the video one by one.

A second problem is that the details of a scene may not be known only by looking at a representative image which is a still image. For example, consider a task of giving a soccer video as an input, finding a shot scene, and adding information.
Since it is difficult to determine whether or not a still image is a shoot scene,
You need to check the video. There has been a problem that a moving image cannot be confirmed only with a representative image list composed of still images.

Prior Art 2 Japanese Patent Application Laid-Open No. Hei 10-51734 discloses a "moving image editing apparatus and moving image editing method" as a method for improving the efficiency of checking the presence or absence of missed shot switching. In the prior art 2, instead of displaying one representative image for one shot, an image extracted at a certain interval from the shot is also displayed, thereby making it easier to find missing detections. ing.

FIG. 11 is a schematic diagram of the interface of the prior art 2.

In the prior art 2, the representative images A1 and C1 immediately after the shot change are displayed in the image display window 300.
Are displayed together with the mark 301 indicating shot switching, and the images A3, B1, and B3 therebetween are also displayed together.

FIG. 11 shows a case where B1 is not detected as a shot change. However, this display method allows the user to easily detect missing detection by observing the image sequence. Furthermore, this prior art 2
In order to make it possible to check the relevant portion in detail as a moving image, a separate window 302 is displayed so that the image can be checked as a moving image when the preview button 303 is operated with a mouse or the like.

The problem of the prior art 2 is that it is necessary to display a large number of representative images for one shot.
Eventually, when the number of shots that can fit on one screen is reduced and a check operation is performed on a long-time video, extra operations such as a window scroll operation increase and work efficiency may decrease. Further, as another problem, when the separate window 302 is displayed for confirming a shot as a moving image, the viewpoint frequently moves, and the burden on the user may increase.

[0017]

In summary, prior art 1 can display many shots on one screen and is suitable for grasping the outline of an image, but has a problem that the image cannot be confirmed as a moving image. Therefore, it is difficult to correct missed shot switching detection.

In the prior art 1, a still image is used as a representative image, but it is also possible to display all images as moving images.

When this method is used, it is possible to perform a check operation with a moving image, and it is possible to fit a large number of shots on one screen. Requires a large amount of calculation power, a problem that the screen becomes too noisy and makes it difficult to concentrate, and a problem that the eyes become tired.

[0020] On the other hand, the prior art 2 enables a confirmation operation with a moving image. However, there are problems in that the number of shots that can be displayed on one screen is reduced, and the viewpoint is moved frequently, and the efficiency of the confirmation operation is reduced. there were.

The present invention has been made in order to solve these problems, and has been made in order to make it possible to quickly understand the details of a video including a motion by efficiently confirming a scene by using a moving image. It is an object of the present invention to provide a simple video listing method and a new recording medium storing a video listing processing program for realizing the video listing method.

[0022]

In order to achieve this object, according to the present invention, a procedure for dividing a video into a plurality of scenes, a representative image is extracted one by one from each of the divided scenes, and displayed as an icon as a list And a procedure for detecting an icon of interest to the user selected by the user, and, when the icon of interest is detected, displaying a video belonging to the scene indicated by the icon of interest on the icon of interest as a moving image. It is characterized by the following.

In the present invention configured as described above, a procedure for detecting an icon of interest by the user is provided, and only the icon of interest detected by the procedure is processed so as to display a moving image. While displaying many scenes, it is possible to check the image with the video icon, and the viewpoint movement becomes complicated, the problem of the efficiency of the check work decreases due to the increase in scrolling operation, display processing, etc. To solve the problem of requiring a lot of computational power, the problem that the screen becomes too noisy and makes it difficult to concentrate, and the problem of tired eyes. This allows efficient work.

Further, according to the present invention, the procedure for dividing the video into a plurality of scenes includes a procedure for detecting a shot change, which is a scene change, and dividing the video into shots.

According to this configuration, there is an effect that information can be added to each unit of a shot, which is often used in video production.

At this time, the moving image display procedure is characterized in that the moving image is displayed repeatedly from the first frame of the current shot to the first frame of the next shot corresponding to the icon of interest.

According to this configuration, the image is displayed not to the end of the current shot but to the beginning of the next shot, so that it is possible to visually confirm the missed shot switching detection.

Further, the present invention is characterized in that the procedure for detecting the icon of interest is a procedure for detecting that the pointing cursor on the computer screen overlaps the icon.

According to this configuration, a window system that can use a mouse (for example, X-Window, Window)
s (registered trademark)).

Further, in the present invention, the procedure for displaying a moving image is as follows:
It is characterized in that the moving image reproduction is skipped and displayed so as to make one cycle within a preset time.

According to this configuration, even a long scene can be reproduced as a moving image within a certain period of time, so that the moving image checking operation can be performed more efficiently.

According to this configuration, an interface for inputting additional information such as a comment for an icon by a user is provided, so that the information adding operation can be performed efficiently.

[0034]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail according to embodiments.

FIG. 1 shows a video processing apparatus 1 equipped with the present invention.
1 illustrates an example of an embodiment.

As shown in this figure, a video processing apparatus 1 equipped with the present invention is connected to a video file 2 storing a video to be processed, and means for interacting with a user in order to realize the present invention. Terminal 3 and video processing program 10
, A moving picture icon display routine 11, a video work file 12, and a time code storage area 13.

Here, reference numeral 4 denotes a display provided in the terminal 3, 5 denotes a keyboard provided in the terminal 3, and 6 denotes a mouse provided in the terminal 3.

The video processing program 10 is installed via a floppy disk, a line, or the like, operates on a memory, and executes main processing of video processing for realizing the present invention. Movie icon display routine 11
Is installed via a floppy disk or a line, operates on a memory, and stores
And executes a moving image icon display process characteristic of the present invention.

The video work file 12 is prepared as a video work file processed by the video processing program 10. The time code storage area 13 stores a time code obtained when a video is virtually divided.

Here, the video processing program 10 and the moving picture icon display routine 11 can be stored in an appropriate recording medium such as a computer-readable portable medium memory, a semiconductor memory, or a hard disk.

FIGS. 2 and 3 show the video processing program 10.
FIG. 4 shows an embodiment of a process flow executed by the moving image icon display routine 11.

Next, according to this processing flow, the processing executed by the video processing apparatus 1 having the present invention configured as described above will be described in detail.

When the video processing program 10 is started, as shown in the processing flow of FIGS. 2 and 3, first, in step 1, the video to be processed is read from the video file 2 and the video work file 12 is read. To be stored.

Subsequently, in step 2, a shot changeover (also called a cut) is detected from the read video to be processed. Specifically, the method disclosed in Japanese Patent No. 2869398, "Method and Apparatus for Detecting Cut Point" can be used.

In the method disclosed in Japanese Patent No. 2869398, as shown in FIG. 5, a compressed image data compressed by the MPEG method or the like is encoded into an inter-screen forward prediction coded image sequence (P in the case of the MPEG method). Picture sequence) and an intra-picture coded image sequence (an I-picture sequence in the case of the MPEG system), and the amount of change in each image sequence is calculated. Since the processing is performed so as to detect a cut point, a shot change is detected from the read processing target video according to this method.

By this shot switching detection processing,
One video is divided into a plurality of shots. actually,
By storing the time code, which is time information of shot switching, in the time code storage area 13 instead of dividing the video data itself, the video is virtually divided into shots.

Subsequently, in step 3, one representative image (referred to as an icon) is extracted (reduced if necessary) for each shot, and the extracted representative images are displayed in a representative image list window 20 as shown in FIG. Display them in order. In the representative image list window 20 shown in this figure, serial numbers (1), (2),.
And the start time of the shot are displayed below the icon.

Here, the representative image list window 20 is
As shown in FIG. 6, a mouse cursor 21 is displayed, and a merging button 22, an add button 23, and a comment input button 24 are provided.

The display form of the representative image at this time is determined according to the method specified by the user, as described in Japanese Patent Application Laid-Open No. H11-224266, “Method of Creating and Using Electronic Video Document and Program Storage Medium”. The representative images are arranged in a form that can follow the time order, such as arranging them in the order of horizontal writing in European languages as shown in FIG. 7A, or arranging them in the vertical direction as shown in FIG. 7B. Will go.

In the example of the representative image list window 20 shown in FIG. 6, nine icons A1, B1, C1,... Are displayed in a list in the order of horizontal writing in European languages from left to right and from top to bottom. ing.

As the representative image to be displayed at this time, the leading image of the shot can be used, or an image after a fixed time from the shot switching can be used as the representative image. At this point, all icons are displayed as still images.

Subsequently, in step 4, when a user operation is awaited and a user operation is detected, in a succeeding step 5, it is determined whether or not the user operation is a request for terminating the process. When it is determined that the request is a user operation, the process is terminated.

On the other hand, when it is determined in step 5 that the operation is not a user operation of a processing end request, the flow advances to step 6 to check whether or not the mouse cursor 21 has been moved over the icon by the user operation. 21
If the icon exists on the icon, it is considered that the user is paying attention to the icon, the process proceeds to step 7, the moving image icon display routine 11 is called to start the moving image icon display process, and then the To wait for the next user operation.

In the example of the representative image list window 20 shown in FIG. 6, since the mouse cursor 21 is positioned on the icon A1, the icon A1 is detected as the icon of interest. As will be described later, the moving image icon display routine 11 performs processing so that only the attention icon is displayed as a moving image. In this case, only the icon A1 is displayed as a moving image. Note that mouse cursor 2
Since the location of 1 is managed by the operating system (OS) of the computer, it can be obtained by inquiring of the operating system.

On the other hand, when it is determined in step 6 that the mouse cursor 21 has not moved over the icon by the user operation, the process proceeds to step 8 and the mouse cursor 21 has moved out of the icon by the user operation. When it is determined whether or not the mouse cursor 21 has moved out of the icon, the process proceeds to step 9 where the moving image icon display routine 11 is stopped to terminate the moving image icon display process, The process returns to step 4 to wait for the next user operation.

In this way, when the mouse cursor 21 remains on the icon, the moving image icon display processing is continued, and when the mouse cursor 21 moves out of the icon, the moving image icon display processing ends. Then, processing is performed so that the icon that has been displayed as a moving image is switched to the still image display.

Next, the moving image icon display processing executed by the moving image icon display routine 11 will be described in detail according to the processing flow of FIG. 4, leaving the description of the processing flows of FIGS. 2 and 3 temporarily.

When the moving image icon display routine 11 is started upon detection of the target icon, as shown in the processing flow of FIG. 4, first, at step 20, the time code storage area 13 is accessed. Then, the start time α of the shot and the start time β of the next shot associated with the attention icon are acquired.

That is, since the time code, which is the time information of the shot switching, is recorded in the time code storage area 13 in accordance with the processing of the video processing program 10, by referring to the time code, the start of the shot associated with the icon of interest is started. The time α and the start time β of the next shot are obtained.

When these two start times α and β are obtained,
Subsequently, in step 21, an initial value “0” is set to a variable i.

Subsequently, in step 22, the time pointed by the variable i among the time points t at which the shot associated with the icon of interest is divided into N equal parts is represented by t = α × (N−i) / N + β × i / N ( i = 0,1,
2,..., N) to obtain (reduce as necessary) the image closest to the time t from the video stored in the video work file 12 Is displayed on the attention icon.

According to this equation, when “i = 0”, the time “t = α” is obtained, so that the leading image of the shot associated with the icon of interest is displayed on the icon of interest. In addition, when “i = N”, the time “t = β” is obtained, so that the leading image of the shot next to the shot associated with the target icon is displayed on the target icon.

Here, N is set regardless of the length of the shot. (N + 1) is the number of frames extracted from one shot, and the larger the N, the smoother the video playback becomes, but the longer the time required for one playback becomes, the longer the checking operation takes. Therefore, it is necessary to set an appropriate value (for example, N = 10) as N.

Subsequently, in step 23, after a predetermined period of time p (for example, 100 milliseconds) has elapsed since the display was started by the process of step 22, it is determined that the predetermined period of time p has elapsed. Then, the process proceeds to a step 24, wherein the value of the variable i is incremented by one.

Subsequently, in step 25, the value of the variable i is set to N
When it is determined whether or not it has become larger, and it is determined that it has not become larger, step 22
When it is determined that the value has increased, the process proceeds to step 26, where the value of the variable i is reset to 0, and then the process returns to step 22.

As described above, when the moving image icon display routine 11 is activated by detecting the icon of interest, the moving image icon display routine 11 has a short time interval p of several tens to several hundreds of milliseconds.
By updating the image displayed on the attention icon, processing is performed so as to display a moving image while thinning out the image of the shot indicated by the attention icon.

This moving image icon display processing is performed by p × (N +
1) (p = 100 ms, N = 10, p × N = 1.
(1 second). Since the moving image makes a round within a certain time regardless of the length of the shot, a long shot can be confirmed in a short time.

If the movement of the moving image is too fast and it is difficult to confirm the moving image, a monitor window 30 described later can be used as an auxiliary. In this case, the fast forward function of the monitor window 30 can be used. The confirmation work is performed while controlling the rewind function, the reproduction function, the stop function, and the like.

When the moving image icon display routine 11 follows the processing flow of FIG. 4, the moving image is displayed from the start frame of the shot associated with the icon of interest to the start frame β of the next shot. On the other hand, a modification can be made so that a moving image is displayed from the start frame α to the end frame (β-1) of the shot associated with the icon of interest.

In this case, for example, the moving image icon corresponding to the shot A is a moving image display in which the image sequence “A1, A3, A5” “A1, A3, A5”. Will do.

However, according to this method, A1, A
Since 3 and A5 are all frames included in the same shot, the picture patterns are similar and there is a problem that it is difficult to know where the moving image has made a round.

On the other hand, in the method of the processing flow of FIG. 4, "A1, A3, A5, B1" and "A1, A3, A5, B1"
Since the display is made up to the first frame B1 of the next shot as in the case of ............, it is easy to understand that the moving image has made one round. In other words, when the image of B1 is displayed, the moving image appears to flash for a moment, and it can be seen that the moving image has made one round at that time.

Further, according to the method of the processing flow of FIG.
It is easy to visually detect missed shot switching.

For example, when the shot B is not detected, the moving image icon corresponding to the shot A is, for example, an image sequence "A1, A5, B2, B6, C1""A1, A5, B2, B6, C1"
............ will be displayed. In this case, when the images of B2 and C1 are displayed, it appears as if flashing twice. By making it appear as if flashing twice, it is possible to perceive that there is a miss in detection of shot switching.

Next, returning to the processing flow of FIGS. 2 and 3, the processing executed by the video processing program 10 will be described.

In step 8 of the processing flow shown in FIG.
When it is determined that the operation is not a moving operation, the step 1
The process proceeds to 0 (the processing flow in FIG. 3), and it is determined whether or not the user operation is a request for merging the representative images (icons).

That is, as shown in FIG. 6, a merge button 22 is provided in the representative image list window 20, and the user can detect that the shot switching is excessive (one shot is more than two shots). When it is determined that the representative images displayed in the representative image list window 20 are to be merged, a plurality of representative images displayed in the representative image list window 20 are selected at the same time, and a merge button is pressed. Since a request for merging the representative images is issued by pressing the button 22, it is determined whether or not the user operation is this merging request (a request to merge a plurality of shots into one).

When it is determined that the user operation is a request for merging representative images (icons) by this judgment processing, the process proceeds to step 11, where shots indicated by a plurality of representative images selected as merging targets are merged. After the representative images are merged, the process returns to step 4 to wait for the next user operation.

Thus, the video processing program 10
After a plurality of representative images to be displayed in the representative image list window 20 are selected by clicking with the mouse 6 (the display colors may be changed so as to be understood),
When it is detected that the merge button 22 has been pressed, it is determined that a merge request for those representative images has been issued, and the representative image earlier in time is left, and the remaining representative images are deleted. Since the representative images are merged and the time codes indicated by the representative images stored in the time code storage area 13 are integrated into one (integrating so that the start time and the end time of the shot remain). is there.

Here, an error correction menu is prepared, and when this error correction menu is selected, the merge button 22
Is displayed, the merging process is performed by displaying the merging button 22 when it is detected that the error correction menu has been selected.

On the other hand, when it is determined in step 10 that the user operation is not a request for merging the representative images (icons), the process proceeds to step 12 to determine whether the user operation is a request for adding the representative image.

That is, when displaying the representative image list window 20 shown in FIG. 6, the video processing program 10 displays the monitor window 30 as shown in FIG. When it is not detected and the user wants to add a representative image to the representative image list window 20, a request to add a representative image is issued using the monitor window 30. It is determined whether or not.

When it is determined that the user operation is a request to add a representative image (icon) by this determination processing, the process proceeds to step 13, where the representative image is interacted with the user using the monitor window 30 so that the representative image is displayed. After adding (adding a shot), the process returns to step 4 to wait for the next user operation.

In the monitor window 30, an image display area 31 for displaying a moving image or a still image, a stop button 32 for stopping the movement of the image, a play button 33 for playing back the image, and a fast forward button 34 for fast forwarding the image are provided. ,
A rewind button 35 for rewinding the image, a scroll bar 36 for changing the current image position in the entire video, and a scroll bar 37 for changing the current image position in the set shot section And an IN button 38 used to set the start time of the shot to be added, and an OUT button 3 used to set the end time of the shot to be added.
9 is prepared.

When the user finds the start position of the shot to be added while scrolling the image displayed in the image display area 31 using, for example, the scroll bar 36, the user presses the IN button 38. When the start time of the shot is temporarily set and the end position of the shot to be added is found, the end time of the shot is temporarily set by pressing the OUT button 39. And
To add a shot that separates the provisionally set time, an add button 23 of the representative image list window 20 is pressed.

In response to the request for adding a representative image (a request for adding a shot), the video processing program 10 registers a provisionally set start time and end time in the time code storage area 13 to create a new shot. The representative image is added by registering and displaying the representative image of the registered shot in the representative image list window 20 additionally.

Thus, the video processing program 10
Displays the monitor window 30 and displays the IN button 3
8, the video time pointed to by the coordinate position of the scroll bar 36 when the button 8 is pressed is set as the temporary start time of the shot, and the video time pointed to by the coordinate position of the scroll bar 36 when the OUT button 39 is pressed is set to the temporary end time of the shot. When it is detected that the add button 23 is pressed, the provisionally set start time / end time is registered in the time code storage area 13 so as to register the shot clipped by the user. It is.

Here, when an error correction menu is prepared and the monitor window 30 is displayed when an addition request is selected from the error correction menu, an addition request is selected from the error correction menu. By displaying the monitor window 30 when
The additional processing described above will be performed.

On the other hand, if it is determined in step 12 that the user operation is not a request to add a representative image (icon), the process proceeds to step 14 to determine whether the user operation is a comment input request.

That is, as shown in FIG. 6, a comment input button 24 is provided in the representative image list window 20, and the user can comment on a shot indicated by the representative image displayed in the representative image list window 20. When it is desired to assign information, a representative image displayed in the representative image list window 20 is selected with the mouse 6, and then a comment input request is issued by pressing the comment input button 24. It is determined whether or not this is a comment input request.

When it is determined that the user operation is a comment input request by this determination processing, step 1
In step 5, the user inputs comment information by displaying the comment input window 40 as shown in FIG. 9 and interacting with the user, and stores the comment information in association with the shot pointed to by the representative image selected by the user ( Then, the process returns to step 4 to wait for the next user operation.

The comment input window 40 includes a representative image display area 41 for displaying a representative image, two text input areas 42 and 43, an OK button 44, and a cancel button 45.

When the user selects a representative image and issues a comment input request, the video processing program 10
The text input from the keyboard 5 is displayed in the text input area 42 or the text input area 43, and when the user presses the OK button 44, the comment input processing ends, and the selected representative image (icon) is pointed out. The comment information is saved in association with the shot, and the comment input window 40 is closed. Then, when the user presses the cancel button 45, processing is performed so as to close the comment input window 40 without saving the input comment information.

By providing such an interface for the comment input window 40, there is an effect that information can be efficiently added in shot units.

If it is determined in step 14 that the user operation is not a comment input request, the flow advances to step 16 to execute a process specified by the user operation, and then returns to step 4 to return to the next user operation. Wait for.

Thus, the video processing program 10
Divides a video into multiple shots, extracts a representative image from each shot one by one, displays it as a list of icons, detects the icon that the user focuses on, and responds when the icon of interest is detected Performs processing such that video belonging to the shot indicated by the icon of interest is displayed as a moving image on the icon of interest.

In the embodiment described above, the video is divided into shots. However, the video may be divided into scenes.

When dividing an image into scenes, not only shot switching, but also camera start / end points, telop (caption) display start / end points, narration start / end points, The video is divided into scenes based on information such as audio switching such as a start point and an end point of music. Needless to say, the video may be divided into scenes by interacting with the user using the switching of shots as a clue.

Various procedures can be considered for detecting the icon of interest to the user. For example, it is possible to program so that the icon of interest can be switched by a keyboard operation, or to use a gaze detection device or the like.

In the processing flow shown in FIG. 4, the moving image updating procedure is repeatedly called, but in practice, a configuration is used in which the updating procedure is called at regular intervals using a hardware timer or the like. It is also possible.

[0101]

As described above, according to the present invention, when an image is divided into a plurality of scenes and processed, an icon of interest to the user is detected, and only the icon of interest is displayed as a moving image. It is characterized by the following.

According to this configuration, while a large number of scenes are displayed on one screen, it is possible to confirm the image by the moving image icon, and the movement of the viewpoint becomes complicated. It solves the problem of reduced efficiency, the problem of requiring a lot of computing power for display processing, the problem of the screen becoming too noisy and difficult to concentrate, and the problem of tired eyes.
This has the effect that efficient work can be performed.

Further, the present invention is characterized in that the procedure for dividing a video into a plurality of scenes includes a procedure for detecting a shot change as a scene change and dividing the video into shots.

According to this configuration, there is an effect that information can be added to each unit of a shot, which is often used in video production.

At this time, the moving image display procedure is characterized in that the moving image is displayed repeatedly from the first frame of the current shot to the first frame of the next shot corresponding to the icon of interest.

According to this configuration, since the display is displayed not to the end of the current shot but to the head of the next shot, it is possible to visually confirm the omission of switching shots efficiently.
