DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for editing media data such as video and sound, and more particularly to an editing method which allows a user to easily and accurately specify a specific position in data. And equipment.

[0002]

2. Description of the Related Art When editing media data, an image is displayed on a display, while an audio is displayed while a sound is actually heard from a speaker or a sound waveform is displayed on a display. In addition, a method of expressing and editing data in a form in which a user intuitively recognizes and easily operates is widely used. In this case, the user performs an editing operation by designating temporal and spatial coordinates on the presented data. That is, when displaying and editing an image on a display, the user designates a pixel position on the display where the image is displayed, thereby designating a portion of the target image to be processed.
In addition, when editing dynamic data such as moving images and audio, the time position can be determined by performing an instruction operation when a specific scene or sound appears from the data being sequentially presented in chronological order. By specifying, the target data is specified.

However, when performing a position specifying operation while confirming the presented data, the position desired by the user is always specified accurately due to a user error, an operation error, or a shift between recognition and operation. You may not be able to. That is, when a point on the display is designated with a mouse, a point different from the target may be designated due to camera shake or the like. In addition, if the specified operation is performed at the timing when the specific data is presented, the specified operation may be performed before the timing to really operate due to mistake, or it may be necessary to confirm the specified data and perform the operation. Due to a slight time lag, it may happen that the target scene or sound is specified behind. Further, an error may occur in the process of presenting the media data, leading to user error. For example, in the case of an image, only rough display is possible due to the resolution of the display, so even if you intend to perform appropriate operations during editing work, if you output it to a higher resolution display or printer, May appear.

[0004] To solve these problems, two types of methods have been used. One is to devise the input by the user, and there are a method of correcting the position input by the user, a method of directly inputting coordinates by numerical values instead of directly instructing the screen with a mouse, and the like. The other is to devise a method of presenting data, which provides a means for enlarging and displaying a part of a screen and changing a reproduction speed of time-series data.

[0005]

The prior art described above has the following problems. Conversely, in the method of correcting the input, since it is not possible to specify other than the specific coordinates, when editing complicated data, it is necessary to make fine adjustments such as changing the correction method according to the situation Become.

In order to specify a coordinate value by a numerical value, a user confirms what coordinate value the target position has and inputs the numerical value using a keyboard or the like. It's not enough to focus on data only. It is necessary to be aware of the coordinate system, and if the range of values increases, the number of input errors increases, and the load of user recognition increases.

[0007] In the case where a means for changing the data presentation method is provided, the user can present the data in a manner that is most easily operated by the user and work. However, during a series of operations, depending on the data to be edited, the type of operation, and the purpose, it is sufficient to roughly specify somewhere within a certain range, and it is not necessary to correct some errors In some cases, it may be necessary to operate within a very narrow range. For example, a situation may occur in which the magnification of the display is changed for the operation of designating only one point.
In such a case, the user may change the display magnification for the one operation and return to the original magnification after the operation is completed, or the user may repeat the operation until the display succeeds without changing the display magnification. You have to start over.

In these methods, depending on the situation, the number of times of operation of the user is unnecessarily increased, so that the advantage of the intuitive operation is lost, and it is not suitable for continuously specifying the position.

In addition, these methods cannot solve the problem of error when presenting data while changing it over time. If the data presented is changing, the user will not know until the part to be specified has passed. Not only in such a case, but a situation often occurs in which an appropriate operation cannot be performed unless the position of the part to be specified is known in the data.

There must be some reason for the background where the user has specified a position different from the target, for example, the mouse has moved at the moment of pressing the button. If the user intends to specify the initial target position, the user performs an operation to eliminate the cause of the erroneous operation, for example, changes the display magnification to widen the allowable range of the operation, and then performs the operation again. Or, you have to repeat the same operation many times until you get a satisfactory result.

[0011] Such a problem also occurs in a case where various parameters for expressing media data, such as a spatial position, a display magnification, a display density, and the like, are designated in addition to a display position of the media data (in other words, a time axis). .

An object of the present invention is to provide a media data editing method and apparatus which enable a user to efficiently and accurately specify parameters of a specific area in media data.

[0013]

SUMMARY OF THE INVENTION According to the present invention, in the case of redoing the operation of a part once specified by a parameter specifying operation, the user in the media data really wants to specify from the parameter specified by the previous operation. Change the conversion ratio of at least one of the parameters that represent media data with respect to the media data that includes the part that is likely to be included, that is, the part specified by the previous operation and its surrounding parts Then, it is re-presented to the user to facilitate re-operation.

[0014]

By changing the method of converting the parameters representing the media data, the media data of the part that the user really wants to specify is re-presented at a ratio more suitable for the specified operation than in the previous operation. For example, the reproduction speed of the media data is reduced to の み only in the vicinity (specific part) of the point designated last time. In this way, it is possible to reduce the number of times of trial and error of the user until reaching the purpose.

[0015]

FIG. 2 is an explanatory diagram showing an example of a moving image editing screen displayed on the display 101. In FIG. 2, reference numeral 200 denotes a display screen of the moving image editing program 800. Reference numeral 201 denotes a menu bar for pulling out a pull-down menu, and 202 denotes a control panel in which command buttons are collected. The user performs a moving image editing operation by performing an interactive operation while selecting menus and buttons on these. FIG. 2 shows a process of cutting out a part of a moving image. Various moving image cutting command buttons are displayed on the control panel 202. That is, 20

Is a “re-operation” button, 206 is a “cancel” button, 207
Are "register" buttons, which are used to designate a start position and an end position of a portion to be cut out from the moving image data, as described later. Reference numeral 208 denotes a start position of a portion to be cut out, and 209 denotes an area for displaying an end position, and displays a frame number in each laser disk. In addition, the moving image data reproduced from the laser disk 102 is displayed at 210, and the number of the counter 211 indicates the frame number of the currently displayed image. 2
An area 12 displays an operation guide message for the user. A mouse cursor 213 is used for input to a menu or a command button.

FIG. 3 shows an example of editing result data stored in the hard disk 104 or the floppy disk 105, that is, moving image editing data. In FIG.
Reference numeral 30 denotes a moving image editing data table for storing data of an editing result, 31 denotes an area for storing a starting position of reproducing a moving image, and 32 denotes an area for storing an ending position, each of which stores a frame number in a laser disk. I do.
The beginning and end frame numbers of a part of the moving image cut out by the cutting operation shown in FIG. 2 are stored in the moving image editing data table 30. In the program for displaying a moving image using the table 30, the frame numbers of the start position 31 and the end position 32 are sequentially read from the top of the table, and the laser disk 102 is reproduced.

FIG. 6 shows an example of data used for displaying a moving image being edited. Reference numeral 60 denotes a moving image reproduction table for editing operation used for displaying a moving image when performing a moving image clipping operation. Reference numeral 61 denotes an area for storing a frame serving as a starting point of reproduction of a moving image, and reference numeral 62 denotes an area for storing a reproduction speed at the time of reproducing a moving image from the starting frame 61. In the process of reproducing a moving image using the moving image reproduction table for editing work 60, data is sequentially read from the top of the table 60, and the moving image of the laser disk is reproduced and displayed at a reproduction speed corresponding to the starting frame from the starting frame to the next starting frame. If there is no next starting frame, the reproduction is continued at the same speed until the processing ends or an explicit stop instruction is given.

In the present embodiment, the moving picture display method at the time of re-operation is changed by rewriting the moving picture reproduction table 60 for editing work. FIG. 6A shows the table 60 at the start of the clipping process, and FIG. 6B shows the table 60 rewritten using the data of FIGS. 4 and 5 at the time when re-operation is instructed.

FIG. 7 is a diagram for explaining an example of reproducing a moving image using the moving image reproduction table for editing work 60 of FIG. In FIG. 7, reference numeral 71 denotes moving image data to be reproduced;
Reference numerals 3 denote 0 at the start of moving image reproduction and display when the first operation and the second operation (re-operation) are performed, respectively.
This is the time axis. The portion connected by the broken line represents the time at which the video of the corresponding frame number is reproduced and displayed.
Reference numeral 74 denotes a position designated by the user in the first operation.

In this embodiment, when re-operation is performed, a moving image is reproduced at a display speed different from that when the operation is performed first. According to the example of FIG. 7, the changing method is to play back the frame designated by the previous operation, ie, before and after the 1065 frame, more slowly (15 frames / sec) than the previous time, and otherwise to the default speed (30 frames / sec). Play back in sec). This is because the input of the user's mouse cannot keep up with the display of the moving image and the input is delayed because the target frame cannot be specified, or the operation is performed momentarily early because the input delay is too alert. This is because it is conceivable. If an erroneous position is specified for these reasons, it is highly likely that the position that the user really wanted to specify is located near the erroneously specified position (1065 frame). Therefore, by playing back the portion where the target to be designated by the user seems to exist, that is, from 1005 frame to 1125 frame in FIG. 7 more slowly than when the previous operation was performed, one by one. The display time of the frame becomes longer, and the user can perform the designation operation after checking the video.

Next, a moving image clipping process to which the present invention is applied will be described with reference to flowcharts shown in FIGS. 8 to 10 and various tables shown in FIGS. FIG. 8 is a flowchart showing an embodiment of the moving image cutout processing in the moving image editing apparatus to which the present invention is applied, FIG. 9 is a flowchart showing details of the cutout range designation processing 804 in FIG. 8, and FIG. It is a flow chart which shows details of display table change processing 808.

In the present embodiment, the moving image 2 is displayed in the moving image display area 210 in the moving image editing program screen 200 (FIG. 2).
10 is displayed, and the frame number of the video is cut out when the user clicks the setting button 203 with the mouse at the time when the first video and the last video appear in the portion to be cut out, respectively. It shall be specified as the start and end of the range.

The user advances the current position of the moving image to near the start point of the range to be cut out in advance, and instructs the moving image cut-out processing 804 by a pull-down menu.
In the video clipping process, first, the user operation data table 50 (FIG. 5) and the video playback data table 60 (FIG. 6)
Is initialized (step 801). In the user operation data table 50, the start position 51, the end position 52, and the number of user operations 53 of the range to be cut out are each set to 0. The moving image reproduction data table 60 stores the current position of the moving image at the starting point 61 for displaying a moving image, the default speed 41 as the reproducing speed 62, and deletes other data (FIG. 6A).

Next, the operation guide message display area 21
2 displays an operation guide for the user (step 80).
2) Perform a moving image cutout range designation process (FIG. 9) (step 804). In the cut-out range designating process, the laser disk reproducing device 1
03 to start displaying moving images (step 90).
0). The user waits for an input while reproducing and displaying the moving image of the laser disk 102 in the moving image display area 210 (step 902).

In the cutout range designation processing, the setting button 2
It is assumed that no user input other than the cutout range setting instruction by clicking the mouse on 03 is accepted. When the first setting instruction is input (step 904), the frame number of the video currently displayed in the moving image display area 210 at that time,
That is, the numerical value displayed on the counter 211 is stored in the cutout range start position 51 of the user operation data table 50 (step 906). Again, the user waits for an input (step 908), and when a setting instruction is input (step 910), the frame number of the video displayed at the time when the second setting instruction is input is set to the cutout range end position 52. (Step 912). Then, the reproduction and display of the moving image is stopped (step 914), the number of operations 53 of the user operation data table 50 is increased by one (step 916), and the process is terminated.

When the starting point and the ending point of the moving image of the portion to be cut out are designated by the cut-out range designating process, the user waits for an input again (step 806). At this time, operations that can be performed by the user include registration of the cutout range specified earlier in the moving image editing data table 30, display of a moving image for confirming the specified range, redesignation of the cutout range (re-operation), and moving image cutout This is the termination of the processing itself.

If the input by the user is the selection of the re-operation button 205 (step 808), the moving image reproduction data table 60 is changed (step 810). In the process of changing the moving image reproduction data table (FIG. 10), the display change method data table 40 for re-operation and the user operation data table 50 are checked (step 1000), and the default speed 41 of moving image reproduction and the speed change rate 42 , And the number 53 of the designated operations performed by the user, the playback speed of the moving image when the speed is changed and displayed slowly is calculated (step 1002). The playback speed after the change is obtained by multiplying the default playback speed by the power of the change rate raised to the number of operations. If the result is not an integer, round up. Next, from the clipping range start position 51 and the reproduction speed change range 43, a portion where the reproduction speed is changed before and after the clipping range start position designated by the previous operation is obtained (step 1004). That is, in this case, the change range 4
Since the number 3 is 60 frames, the reproduction of the video in the range of the front 60 frames and the rear 60 frames is performed more slowly than the video of the frame number 1065 stored at the start position 51. Similarly, the cutout range end position 52,
From the change range 43 of the reproduction speed, a portion where the reproduction speed is changed before and after the end position of the cutout range designated last time is obtained (step 1006).

The contents of the moving image reproduction data table 60 are changed from the changed moving image reproduction speed obtained by the above processing and the range of changing the moving image reproduction speed (step 1008).
That is, the starting point 61 of the moving image display from the top of the table
In the moving image data, the number of the first frame of a continuous range in which reproduction display is performed at a constant speed is stored, and the corresponding reproduction speed 62 stores the reproduction speed of the moving image in that range. However, the starting point 61 of the moving image display of the first item is shown in FIG.
Similarly, the current position of the moving image at the time when the moving image cutout process is started is stored. FIG. 6B shows the moving image reproduction data table 60 after the change. In this example, before and after the range where slow playback is displayed around the start position and end position of the cutout range, there is an image that is displayed at the default speed without changing the speed, but at the position specified by the user in the previous operation. Depending on the speed, the speed change range around the start position and the speed change range around the end position may overlap each other, even up to the first video.
The data in the re-operation data table 40 can be freely set by the user, and the speed at the time of the re-operation and the change range of the speed can be changed.

Referring back to FIG. 8, the moving image reproduction data table 6
When the change of 0 is completed, a new moving image reproduction data table 6
While the moving image is reproduced and displayed in accordance with 0, the operation of specifying the cutout range of the moving image is performed again (step 804), and the user waits for an input again (step 806). At this time, the number of operations 53 of the user operation data table 50 is increased by one by the moving image clipping range designation processing, so that when a re-operation is instructed next time, the reproduction is performed more slowly in the range where the speed change is performed than this time. The display will be performed.

If the user input is to select the confirmation button 204 (step 812), the frame number of the start position 51 of the user operation data table 50 is set so that the user can confirm the cut-out range set by the previous operation. The moving image is reproduced and displayed from to the frame number of the end position 52 (step 814). When the reproduction of the moving image is completed, the process waits for a user input (step 806).

If the user's input is the selection of the cancel button 207 (step 816), nothing is performed and the moving image clipping process is terminated. When the user input is the selection of the registration button 206 (step 81
8) The start position and the end position of the cutout range set by the user in the previous operation, that is, the cutout range start position 51 and the end position 52 of the user operation data table 50.
Is stored in the moving image editing data table 30 (step 820).

In this example, the display speed is reduced every time the user performs the operation again. However, as a cause of the erroneous operation, a simple mistake that can be recovered without changing the display speed, for example, the operation should be performed Since there may be a delay in operation due to attention being paid to other things at the moment, the speed may be changed every two to three times instead of every time.

Further, in this example, the portion for changing the display speed of the moving image is determined based on the position specified by the previous operation. There is a possibility that a position distant from the target position may be specified, and the display speed of the moving image may always be changed based on the position specified in the first operation.

In this example, the position of the position designated last time is
The video of the same range before and after is displayed at different speeds,
The range for changing the speed may be changed before and after the designated position. Because the reason for the user to specify a position ahead of the target position is not always the same as the reason for specifying the rear position, there is an appropriate range for changing the speed, that is, there is a real target position. The ranges that are likely to do so may be different.

Further, if the user operates too quickly because, for example, an image similar to the target is displayed, the true target position does not always exist within a certain range behind the designated position. In order to cope with such a case, a certain range may be displayed before the designated position, and slowly after the designated position until the user performs an operation of designating the position.

When there is an area where the user is unlikely to perform the designation operation, for example, when a very long moving image is cut out, not only the area where the target position exists is displayed slowly but also Other areas may be displayed at a higher speed than at the time of the first operation. By skipping the area that is not related to the specified operation, information that is not related to the current operation can be cut to avoid confusion for the user, and the waiting time for the user can be reduced, and the editing operation itself can be performed quickly. It can be carried out.

When editing media data, it is difficult to perform accurate processing with a single operation, depending on the complexity of the data itself and the content of the editing. The cause may be a simple user operation error, or may be due to the nature of the data as in the case of dynamic data such as a moving image, and cannot be dealt with in all cases. Therefore, in the process of editing work, re-operation always occurs. By applying the present invention, when re-operation is performed, data can be re-presented to the user so that the operation can be performed more easily, instead of operating under the same conditions as when the previous operation was performed. Editing can be performed efficiently with a small number of operations, without repeating it many times.

In the above example, when data is re-presented when re-operation is instructed, the presentation method is changed. However, the present invention is limited to only the case where re-operation is explicitly instructed. No need.

The procedure for editing the media by a human being, the details of the data to be created are all determined in advance,
It is rare to make things exactly as it is, and it is more or less necessary to decide details while editing and to see the balance of the whole if it is made partially.
For example, a rough sketch is created, and then each part is detailed to create completed data. If you're editing a video and want to create an index that allows you to search for each scene in the video, first specify roughly where you want to index all of them, and then How to specify, but the whole outlook is good and easy to work. At that time,
While playing and displaying the video at a high speed, roughly specify the position, then at the slow speed before and after the first specified portion, and at the other It is advisable to specify the position.

In the example described above, the case where the present invention is applied to the editing of a moving image has been described. However, the present invention can of course be applied to the editing of other media data. Also, other parameters representing the media data,
For example, the spatial position can be changed.

FIG. 11 shows another example of the parameter change, in which the image is enlarged and displayed as compared with the previous time at the time of re-operation. 1101 denotes image data to be edited, 1102
Reference numerals 1103 and 1103 denote areas for displaying an image to be edited when the image is edited.

FIG. 12 shows an example of the display screen 200. In this example, it is possible to specify not only a frame to be cut out but also a portion on the image to be displayed on the screen. FIG. 13 shows data 60 finally generated by the moving image editing program.
As shown in (1), information 65 of those display areas is added to the frame number. In the example of FIG. 13, the specified area is displayed in an enlarged manner in the range of frames 216 to 336.

The designation of the display area may be performed separately after the designation and registration of the cutout range of the moving image, or the display area may be designated when the cutout range is designated and registered together. It may be. The latter case is shown in the flowchart of FIG. In this example, a button of “area designation” is provided on the moving image cutout screen of FIG. 2 (FIG. 14, step 822), and the screen of FIG. 12 is called, and a display area is designated by mouse operation (step 824).

FIG. 15 shows an example of the display area change (824).
Shown in By default, as shown in the data table 80 of FIG. 16, the entire image is displayed, the user is allowed to specify a display area (steps 1504 to 1506), and the result is recorded in the user operation record table 81 shown in FIG. (Step 1504). When re-operation is specified in step 1508, the contents of the image display table 82 (FIG. 18) used to display an image on the editing screen are updated (step 1510). That is, a range (display table B in FIG. 18) in which a certain margin (for example, one side 100) is added to the area (display table A in FIG. 18) designated by the previous operation is displayed in an enlarged manner.

When re-operation is performed as shown in FIG. 11, appropriate processing can be performed by automatically enlarging and displaying. For example, when the area around the position you are trying to specify happens to be complicated and a part different from the target is inevitably specified, or when you want to perform a little more delicate processing, repeat the same operation many times, However, there is no need to change the magnification of the data in the editing field of view.

FIG. 19 shows the previous image 1102 at the time of re-operation.
This is an example in which an image is displayed smaller than the image (image 1103). When editing a very large image, or when editing a small image by partially enlarging it for fine work, the entire image cannot be grasped during the work. The exact position may not be specified. For example, there is a case where a map or a design drawing is edited depending on the semantic contents of the drawing. When marking a road to a certain destination on the map, work cannot be performed unless the positional relationship between the destination and the current position is known.

In the examples shown in FIGS. 11 and 19, the upper, lower, left, and right sides are uniformly enlarged or reduced. Of course, they may be enlarged or reduced at different ratios, or may be obliquely extended depending on the type of data. May be deformed.

In the case where it is difficult to specify the image even after repeated operations, the same whole image 1103 as the original image 1101 may be displayed and operated again as shown in FIG. In this case, a method is conceivable in which a table 81A for counting and displaying the number of operations is provided in the table 81 of FIG.

FIG. 20 shows the previous image 1102 at the time of re-operation.
(Image 1)
103) This is an example. This example is effective in the following cases. That is, as a method of cutting out a moving image, in addition to a method of simply specifying a frame number by a user's eyes, a method of specifying a specific object in a moving image and extracting a frame in which the object exists is also considered. Can be For example, as shown in FIG. 21, when the user specifies the contour of an object in order to add processing to a region where a specific object exists in the image (step 834), the contrast is changed (step 834). 840), the place to be designated can be easily understood. As an example, as shown in FIG. 22, in order to specify an object in an image of a certain frame, the periphery (edge) of the object 250 is specified with a mouse.

However, in order to specify an object in an image and to cut out a frame using the object, it is necessary to process the image data once by loading the image data into the memory, instead of simply reproducing and displaying the LD.

The enhancement of the contrast (step 840) is realized as follows. If the image data is RGB 8
Assuming that each pixel has a bit configuration, R (x), G (x), B (x)
Are converted and shown in Equation 1.

[0054]

(Equation 1)

By default, a = 0 and b = 256 as shown in the table 84 of FIG.
Let a = i × ca and b = 256−i × cb. i is the number of operations performed so far, ca and cb are appropriate constants.

In this example, the image to be edited is displayed while changing the contrast of the entire image. However, it is also possible to change only a few pixels around the position designated by the previous operation.

In the above-described example, the method of presenting data in the temporal or spatial vicinity of the position designated by the first operation is changed. However, a data set including a target to be designated is included. Is important. For example, pixels having the same or similar color as the designated coordinates may be displayed in an emphasized manner.

[0058]

As described above, according to the present invention, when an operation for designating a parameter of a specific area in media data is redone, a method more suitable for a user operation than when the previous operation was performed. , The user can easily and quickly specify the target parameter.
