Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a moving image editing apparatus used for moving image program production such as video information library creation, television broadcast program production, video program production, etc., and particularly uses a program for executing moving image editing operation. The present invention relates to a moving image editing apparatus that is controlled by a computer and edits a moving image and adds information based on an instruction from an operator.
[0002]
[Prior art]
With the advent of the multimedia era and the multi-channel era, the demand for video programs has been diversifying for both creators and receivers. For this reason, from the viewpoint of reusing video information, Efficient management and how easy it is to search is an important issue, and program delivery methods that allow the receiver to quickly and selectively watch videos of their interest have been seriously studied. .
[0003]
By the way, generally, image information by moving images such as television image information is composed of a series of a plurality of scenes (scenes).
Therefore, when such a moving image is recorded, identification information indicating a start point or an end point may be inserted at a scene break in order to facilitate subsequent processing such as editing.
[0004]
For example, in a video such as a sports broadcast, it is customary to record the time when a specific event begins as the in point (start point) and the end time as the out point (end point) together with the video. However, the recording positions of these in and out points have conventionally been determined by an operation in which an operator actually monitors a video and operates a button at a predetermined time while checking the scene.
[0005]
For example, in some video editing apparatuses according to the prior art, when image data recorded on two video tapes is used to create a new program and record it on the video tape, the operator plays back from the original video tape. The desired frame of the selected image can be found using the jog function or shuttle function, and can be arbitrarily set by operating the mark in (MARK IN) or mark out (MARK OUT) button.
[0006]
On the other hand, when recording video data, an apparatus that allows a predetermined frame to be registered by operating a keyboard or mouse with a desired cut while an operator sees an image that appears in real time has also been known. At this time, an apparatus that automatically detects a change point of an image by an image recognition technique and registers the change point as a cut break point has been conventionally known.
[0007]
As a method for automatically detecting the change point of this image, for example, as disclosed in JP-A-2-184181, the illuminance, volume, color tone, etc. of the moving image are analyzed, and these changes are analyzed. A technique for detecting a marked portion as a change point of a cut image is used. Regardless of which device is used, registered points or cut break points are sequentially in and out points.
[0008]
[Problems to be solved by the invention]
The above prior art does not give consideration to the points that require skill in recording identification information, such as the in point and the out point, and there is a problem that it takes a lot of labor and time to record accurate identification information. there were.
[0009]
In other words, there is a slight delay in human reaction time, so even if the operator recognizes the above-mentioned scene break from the image that changes on the monitor and changes every moment, Is accompanied by a slight delay, and it is inevitable that there is a slight deviation (mainly a delay) at the time of recording the identification information.
[0010]
Especially when there are many events that occur in the same scene, such as sports broadcasts, and the subject is moving very rapidly in the image, it is already difficult to recognize the event itself, Setting the in and out points is extremely difficult.
[0011]
Therefore, in the prior art, it takes a lot of labor and time to record accurate identification information.
An object of the present invention is to provide a moving image editing apparatus capable of easily recording the above-described identification information easily.
[0012]
[Means for Solving the Problems]
The above purpose is based on a predetermined input operation between moving images. Editing points In the moving image editing apparatus configured to insert the image, a mode for creating an index for a desired image is created, the time when the input operation is performed, and the moving image by the input operation. Editing points Compensation time to compensate for the difference between the time when the input operation was performed and the time when the edit point is actually set is between the time when the character is inserted and the mode including at least automatic detection, editing, soccer, and baseball This is accomplished as it is added.
[0013]
At this time, means for setting the duration of the scene may be provided, and one of the identification information may be automatically set by an input operation, and index information is created for the identification information. You may be made to do.
[0014]

[0016]
The memory 302 stores various control software used by the CPU 301, and includes, for example, a frame number of a series of moving images, an M-icon (Moving Icon) to be displayed on the display screen, an M-icon file name, and the like. It serves to temporarily store various control information used in moving image editing and index creation.
[0017]
Here, the M-icon will be described. The “M-icon” is a display for displaying a moving image consisting of a plurality of frame images or an image between in and out points at high speed. Alternatively, it is a reduced image for display in which the size of the screen is reduced by a predetermined ratio for display when a button (described later) is input or when an image of a frame detected by image recognition is viewed.
[0018]
The image recognizing unit 303 functions to automatically detect a specific frame from a series of moving image information through image recognition processing, which will be described in detail later.
The video signal source 304 is a source of moving image signals that require editing processing and / or index creation processing by the moving image editing apparatus 300. is there.
[0019]
The video interface 305 converts an image signal of a moving image input from the video signal source 304 into image information of a predetermined format suitable for processing in the moving image editing apparatus 300, and includes a memory 302, an image recognition unit 303, In addition to functioning to output to the magnetic storage device 306, the image information of the moving image output from the information storage device 306 after being subjected to moving image editing processing and index creation processing is in the same format as that supplied from the video signal source 304. The image signal is converted into an image signal and output from the image signal output 311.
[0020]
The magnetic storage device 306 is composed of, for example, a hard disk storage device capable of random access, and stores image information of a moving image that is converted into a required format and supplied by the video interface 305 and temporarily stored in the memory 302. It functions to store various editing information and control information for editing processing and index creation processing, such as an M-icon.
[0021]
The magnetic storage device 306 is not limited to the magnetic recording system, and may be implemented using an arbitrary storage system as long as random access is possible and a necessary storage capacity and necessary storage read performance are provided. be able to.
[0022]
The frame buffer memory 307 functions to store image information to be displayed on the monitor 308.
The monitor 308 is a display device for display, and functions to display a processing status by the CPU 301, an input status at the time of input operation, and an image detected by image recognition and an editing status.
[0023]
The input device 309 includes, for example, a mouse and a keyboard, and functions as a man-machine interface for the CPU 301 such as inputting a command to the CPU 301.
The bus 310 is for digital information transmission between the devices in the moving image editing apparatus 300.
[0024]
Therefore, according to the embodiment shown in FIG. 3, by storing necessary software in the memory 302, image information of a moving image to be edited is stored and managed in the memory 302 and the magnetic storage device 306. On the screen of the monitor 308, the moving image stored in the memory 302 and the magnetic storage device 306 or the reduced moving image is displayed as an M-icon, and the moving image can be edited.
[0025]
Next, terms used in the following description will be defined.
<Offset>
Compensation time is the time to compensate for the difference between the time when the input operation was performed and the time when the edit point was actually set.
<Duration>
The duration of the scene, which is the time set between the in point and the out point.
[0026]
<In type>
Of the edit points, this is a button that sets the in point that will be the edit start point. The frame when this button is pressed is set as the in point.
Here, when offset is specified, the time takes the offset value into consideration.
[0027]
<Out type>
Among the edit points, this is a button that sets the out point that will be the end point of editing. The frame when this button is pressed is set as the out point.
Again, when offset is specified, the time takes this offset value into account.
[0028]
<In_out type>
A button that sets the time when the button is pressed as the in point, and automatically calculates and sets the time at the out point after the preset time (duration) has elapsed for this in point.
Similarly, when offset is specified, the time takes this offset value into account.
[0029]
<Out_in type>
A button that sets the time when the button is pressed as the out point, and automatically calculates and sets the time at the in point after the preset time has elapsed for the out point.
Again, when offset is specified, the time takes this offset value into consideration.
[0030]
<Out_out type>
A button that replaces the image, time, and name of the previous out point with the image, time, and name when this button was pressed.
<Mark type>
A button that retains the input information without adding the in or out attribute.
[0031]
<Name 1>
A button that sets the name of each button.
<Name 2>
A button for setting a name on the side calculated and set by the CPU 301 by an in_out type or out_in type button.
Therefore, the in_out type is set to the out point, and the out_in type is the in point.
[0032]
Next, the operation of this embodiment will be described with reference to the flowchart of FIG.
First, when the moving image editing apparatus 300 is activated (process 400), the image of the mode selection panel 200 shown in FIG.
At this time, in this embodiment, only the automatic detection button 201 and the edit button 202 are initially formed in the mode selection panel 200. However, depending on the embodiment, the automatic detection button 201 may be omitted. Good.
[0033]
Therefore, the operator creates a mode for creating an index for a desired video. In other words, a man-machine interface screen (hereinafter referred to as a mode screen) in which the type and arrangement of buttons specialized for describing the video of the genre is created.
[0034]
Specifically, in the mode selection process 401, the add button 206 created on the mode selection panel 200 in FIG. 2 is pressed, and the process 700 is shifted to the process 700 shown in FIG.
Here, pressing the button means designating a button figure on the screen displayed on the monitor 308 with a cursor and clicking the mouse.
[0035]
At this time, the buttons 205 and 209 to which no mode has been assigned are displayed in gray, and they are ignored even if they are pressed, except when the add button 206 is pressed.
[0036]
When the processing shifts to the processing 700 in FIG. 7, a button for assigning a mode to be added is designated with the mouse.
For example, if the button 205 is pressed, the process proceeds to process 701, and an image of the panel 500 for setting the type and name of the button is displayed as shown in FIG. 5 (process 702).
Therefore, the mode name is entered in the mode name setting field 512 shown in FIG. 5, and the name of the new mode that is being created is set (step 703).
[0037]
Next, the number of buttons used in this mode is set (process 704).
As a setting method at this time, there are a method in which a numerical value is directly input from the keyboard in the designation area 501 on the panel 500, and a method in which the setting button 502 is pressed.
[0038]
Here, the maximum number of buttons that can be used and the display position are set in advance in consideration of the size of the screen. In this embodiment, a maximum of 10 buttons can be set. The description will be made assuming that the settings are made as shown.
[0039]
When the number of buttons is designated in this way, a setting GUI (Graphical User Interface) area 503 in which the number of buttons is displayed is displayed.
Next, the button type is set (step 706). At this time, the duration box 507 and the name 2 box 508 are grayed out and cannot be input. Here, the box and the button have the same meaning.
[0040]
If the button 504 is pressed here, a menu 600 screen shown in FIG. 6 is displayed.
Therefore, the operator next selects a desired type from the menu 600 (process 707). Then, the screen of this menu 600 disappears, and the screen of the original panel 500 is displayed again, and items that need to be set are displayed according to the currently selected type.
[0041]
Here, since the types of various buttons, items that need to be set, and contents are as described above, the setting method will be described.
First, the panel 500 of FIG. 5 shows a button 504 when the type in button in the menu 600 of FIG. 6 is selected.
[0042]
In the case of this type, next, name 1 is set as shown in FIG. 7 (process 708). The method is to click the name 1 box 505 with the mouse and then enter the name from the keyboard.
Next, an offset value is input (process 709). At this time, similarly, the user clicks the offset box 506 with the mouse and inputs a numerical value from the keyboard.
[0043]
The above is the case where in, out, out_out, mark type buttons are set in the process 707 of FIG. 7, but when the in_out type or out_in type button is selected, the following items are also set. It is necessary to perform processing.
[0044]
That is, first, the name 1 setting process 710 and the offsert value input process 711 are executed in the same manner as described above, but after this, the duration type is set (process 712).
[0045]
In this operation, similarly to the offset setting process, the user clicks the box 507 with the mouse and inputs a numerical value from the keyboard.
Thereafter, name 2 is set (process 713). This is the same as the setting process for the name 1, and the input box 508 is clicked with the mouse and the name is input from the keyboard.
[0046]
When the process 709 or 713 is completed, the process returns to the process 705, and the operator repeats the above operation until the setting of all buttons is completed.
When setting a button that is not displayed on the screen, if the slider 510 is operated, the setting box can be displayed, and the setting process can be executed.
[0047]
In this way, when all the buttons have been set, if the OK button 509 is pressed, this setting is validated and the panel 500 is closed.
At this time, for example, if there is a setting error such as an input error, an incorrect numerical value input, or the in and out points are reversed in time, a warning message is displayed and a correction is prompted.
On the other hand, when the CANCEL button 511 is pressed, the set contents are discarded.
[0048]
Next, the types and contents of buttons and items that need to be set for each type will be described.
In the moving image editing apparatus 300 according to the embodiment of the present invention, as described above, the operator creates the index according to the type of the input video, so that the type and number of buttons are set within a preset range. Set arbitrarily, create an "index creation mode", and use this to proceed.
[0049]
In this embodiment, in order to specify the in point and the out point, as shown in FIG. 8, four types (forms) of in_out, out_in, out_out, and mark are added, so that a total of six types of processing 800 are performed. ... 805 can be set as buttons.
Hereinafter, each type of processing will be described.
[0050]
800 is an in type. As described above, this is a process of setting the frame at the time of the button input (time when this value is specified) as the in point. Is the following processing.
[0051]
That is, if the operator depresses an in-type button, the CPU 301 displays an image of the time at a predetermined position on the monitor 308 with an M-icon, and also displays the time and button name. The time, button name, and attribute indicating that the frame is the in point are added and recorded in the memory 302.
[0052]
Reference numeral 801 denotes an out type, which is also a process for setting an out point as described above. When the operator presses a button of the out type, the time and the time are displayed on the monitor 308 as in the case of the in point. The image at this time and the button name are displayed, and the time, the name, and the attribute of the out point are recorded in the memory 302.
[0053]
802 is an in_out type, and as described above, the time when the button of the in_out type is pressed (when offset is set, this offset is taken into account) is set as the in point. This is a process for automatically calculating and setting the time of the out point after a preset time (this is the duration) has elapsed.
[0054]
When the operator presses an in_out type button, the image corresponding to the time corresponding to the in point, the time and the button name are displayed on the monitor 308, and the attribute of the time, the name, and the in point is recorded in the memory 302. Is done.
Further, after the duration time with respect to the in point at this time, the image of the time and the name and time preset on the screen of FIG. 5 are displayed on the monitor 802, and the time and name are also displayed on the memory 302. And out point attributes are recorded.
[0055]
803 is an out_in type, and as described above, the time when the button of the out_in type is pressed (when offset is taken into account) is the out point, and the time before the out point is set by the preset time (duration). Is the process of calculating in to the in point.
[0056]
When the operator depresses an out_in type button, the time of depressing on the monitor 308 and the time of the in point based on the preset offset and duration are calculated, and the video at the time is displayed as an M-icon in the magnetic storage device. The information is read from 306 and displayed on the monitor 308. In addition, a preset name and time are displayed on the screen of FIG.
[0057]
In addition, the memory 302 records the time, name, and in point attributes, and the video corresponding to the button press time (considering offset), the button name, and the time are displayed on the monitor 308 as the out point. In the memory 302, the time, button name, and out point attribute are recorded.
[0058]
Reference numeral 804 denotes an out_out type, which is a process for replacing the previous out point with the image, time, and name when the out_out type button is pressed (considering offset).
When the operator presses an out_out type button, the “image, name, and time of the most recent out point set before that” displayed on the monitor 308 is changed to “image, button name, The time is changed to “time”, and the time, name, and out_out attribute are recorded in the memory 302.
[0059]
Reference numeral 805 denotes a mark type, which is a process for holding only button input information without adding an in or out attribute.
When the operator depresses a mark type button, the image, time, and button name of the time (considering offset) are displayed on the monitor 308, and the time, name, and mark attribute are recorded in the memory 302.
In any case, information recorded in the memory 302 is appropriately stored in the magnetic storage device 306.
[0060]
Next, setting items will be described.
In FIG. 8, reference numerals 807 to 810 denote setting items.
An item 807 is used for setting the name 1 and determines the button names of the buttons 801 to 805.
The name set here is displayed on the screen when the button is pressed, and a file or the like is described when the index is created. This item also needs to be set for all buttons.
[0061]
An item 808 is for specifying an offset, which is for correcting a difference between the time when the operator presses the button and the time actually specified, and is specifically as follows.
That is, this offset function mainly corrects the delay until the operator confirms the input video and presses the button, and is a feature of this embodiment. Therefore, hereinafter, the offset function will be described in further detail. Explained.
[0062]
When the video signal 304 is input via the video interface 305, it is recorded in the magnetic storage device 306. At this time, the CPU 301 constantly monitors the operation state of the input device 309.
When the button is pressed by the operator, the CPU 301 determines the type of the pressed button and the pressed time, and executes the processing set for the button.
[0063]
In FIG. 9, first, the time when the operator presses the button is set to 900.
Now, assuming that a plus time is set as offset, the CPU 301 displays an image at time 901 when the plus time has elapsed on the monitor 308, and stores the time in the memory 302.
[0064]
Next, assuming that a negative time is set as offset, the CPU 301 causes the monitor 308 to display an image at a time 902 before the negative time, and stores the time in the memory 302.
On the other hand, if zero is specified as offset, an image at time 900 when the button is pressed is displayed, and the time is stored.
[0065]
Here, the offset setting can be specified in units of seconds, for example, and the setting is performed for all types of buttons. Therefore, when data at the time of button input is required, offset zero is set. Just enter it.
[0066]
An item 809 is for specifying a duration. This is a function specific to the in_out type button 802 or the out_in type button 803, and specifies the duration between the in point and the out point, that is, the duration. .
At this time, if offset is specified for the in point or out point, the time of the corresponding out point or in point is calculated in consideration of this value.
[0067]
The duration function will be described below with reference to FIG.
First, (1) in FIG. 10 is an in_out type, and the offset by the button is zero.
At this time, the time when the operator presses the button is the in point 1001, the time when the specified duration 1002 has elapsed is calculated as the out point 1003, and the image, time, and name are displayed on the monitor 308 as described above, and the memory It is stored on 302 together with the attribute of in point or out point.
[0068]
Next, (2) in FIG. 10 is the case of the out_in type, and the designated offset is also zero.
At this time, as in the case of FIG. 10 (1), the time when the operator pressed the button becomes the out point 1004, and the time when the specified duration 1005 returns to the past is calculated as the out point 1006. Is displayed on the monitor 308 and stored in the memory 302 together with the attribute of in point or out point.
[0069]
Next, the case where offset is set for the in_out type and out_in type buttons will be described using the in_out type as an example.
First, FIG. 10 (3) shows a case where offset is plus (positive), and when the operator presses the button, the CPU 301 calculates the time when the offset time 1008 has elapsed from the pressed time 1007 and sets it as the in point 1009. Further, the time when the duration 1010 has elapsed is calculated and set as an out point 1011. After that, the CPU 301 displays the image, time, and name on the monitor 308 for each time, and stores them in the memory 302 together with the attribute of in point or out point.
[0070]
Next, FIG. 10 (4) shows a case where offset is negative, and when the operator presses the button, the CPU 301 displays an image that is the time 1012 before the time 1012 at which this button was pressed, by the magnetic storage device 306. The image, the time, and the name are displayed on the monitor 308 as the out point image, and the time after the lapse of 1015 hours from the time is displayed, and the attribute of the in point or out point is displayed in the memory 302. Store.
[0071]
At this time, for the absolute value | offset |
｜ offset ｜> duration
Since the out point also becomes the past time, the CPU 301 reads the image from the magnetic storage device 306 and displays it.
[0072]
Finally, name 2 of item 810 will be described. This is also a function specific to in_out type button 802 or out_in type button 803, and is calculated based on a preset duration as described above. The name is set to the in point or the out point, and this name is displayed at the corresponding position on the monitor 308 and stored in the memory 302.
[0073]
As described above, when all the buttons are set and the OK button 509 is pressed, a new mode is added to the mode selection panel.
At this time, the name displayed on the button is the name described in the button 505 of name 1 on the screen of the panel 500 in FIG.
[0074]
Next, a method for deleting a mode will be described.
As described above, when the moving image editing apparatus 300 is activated (process 400), the image of the mode selection panel 200 shown in FIG. 2 is displayed on the display surface of the monitor 308, and the mode selection process 401 is performed.
Here, when unnecessary modes are to be reduced, the delete button 207 is pressed (process 403), and the process proceeds to the process of FIG.
[0075]
Then, the button of the mode to be deleted next is designated with the mouse (process 714).
Then, the setting of the mode is canceled (process 715), and the button (for example, soccer button 203) 207 is displayed in gray (process 716).
As a result, the mode can be deleted.
In this deletion operation, the automatic detection button 201 and the edit button 202 are displayed in gray so that they cannot be deleted.
[0076]
Next, the procedure and method for creating an index for the input video and the screen display at this time will be described.
First, it is assumed here that the soccer mode and the baseball mode are created as described above.
Then, when the moving image editing apparatus 300 is activated and the image of the mode selection panel 200 is displayed on the monitor 308, the soccer button 203 and the baseball button 204 are displayed on the screen as illustrated.
[0077]
Therefore, the operator selects a desired mode. Here, the explanation will be made assuming that the soccer mode is selected.
When the operator presses the soccer mode button 203, the CPU 301 returns to the process of FIG. 4 and reads the setting information of the mode read on the memory 302 (process 404), and in accordance with this information, the operation window 100 shown in FIG. Is displayed on the monitor 308 (process 405).
[0078]
At this time, if an automatic detection program (described later) by image recognition is incorporated, the automatic detection mode is entered instead of the manual indexing mode, and the process proceeds to process 404 after the recognition process 411 is executed.
[0079]
In the operation window 100 displayed on the monitor 308 in this way, the video that is currently input is displayed in the area 101, and various buttons 109 created by the above-described method are displayed in the area 102.
Therefore, the operator performs setting work while watching the video displayed in the area 101.
[0080]
Here, when the start button 108 is pressed (process 406), the CPU 301 takes in the video signal from the video signal source 304, creates an M-icon from this video signal, and stores it in the magnetic storage device 306 together with the original video information. To start.
[0081]
When the end button 107 is not pressed and any of the button group 109 is pressed (processing 410, processing 407), or when an image is detected by recognition processing described later, the area 103 stores the image. The M-icon is displayed, the time is displayed in the area 104, and the name 1 specified in the box 505 or the name 2 specified in the box 508 is displayed as characters in the area 105. The
[0082]
Here, FIG. 1 is a display example of the operation window 100 when the operator depresses the shoot button 109 (when the process proceeds from the process 407 to the process 408), and a shoot is displayed in the area 105.
[0083]
Details of the processing 408 by the CPU 301 at this time will be described.
In this process 408, first, as shown in FIG. 11, the process branches depending on the type of button pressed by the operator (process 1101).
First, the case where the in, out, and mark types are selected and the processing proceeds to step 1102 will be described with reference to FIG.
[0084]
First, it is determined what value is set in offset (processing 1106).
If the offset value is positive, the time according to the offset, that is, the passage of time is monitored until the time is reached, and data (image, time) is acquired at the time (processing 1107). .
[0085]
On the other hand, when the offset value is negative, it means that the data at the time before the button is pressed, that is, the past data is requested, so that the image stored in the magnetic storage device 306 (M -An image at the time is read out from the icon (process 1109).
On the other hand, when the offset value is not set, that is, when 0 is input, the data at the time when the button is pressed is acquired, and the process proceeds to the next process (process 1108).
[0086]
Therefore, after this, processing 1110, processing 1111 and processing 1112 are executed, so that each image and time obtained as described above (time considering offset), and button names are displayed in the operation window. It is displayed in each of the 100 areas 103, 104, and 105.
Here, the display of the area 105 is a description of name 1 in the box 505 in FIG.
[0087]
Next, a case where the in_out type is selected and the processing proceeds to processing 1103 will be described with reference to FIG.
First, also in this process 1103, the first process 1201 is a process of checking the value of offset.
[0088]
Then, after any one of the processing 1202 and processing 1203 and processing 1204, processing from processing 1205 to processing 1207 is executed, whereby display in each area of the operation window 100 is obtained. 11 is the same as the processing from processing 1107 to processing 1112 in FIG.
[0089]
Accordingly, in the process of FIG. 12, next, the value of duration is referred to (process 1208). Here, duration is the setting of the duration between the in point and the out point, as described above, and therefore there is no negative value.
[0090]
First, when the duration value is positive, the passage of time is monitored until the time reaches the time, and data is acquired at the time (processing 1209).
On the other hand, when the value of offset is 0, the data at the time when the button is pressed, that is, the same time as the in point is acquired (process 1210).
[0091]
Thereafter, processing 1211, 1212, and 1213 are executed to obtain a display in each area of the operation window 100.
And the display of the area | region 105 at this time becomes description of the name 2 by the box 508 of FIG.
[0092]
Next, a case where the out_in type button is pressed and the process proceeds to processing 1104 will be described with reference to FIG.
First, the CPU 301 refers to the duration value (process 1301).
If the duration value is positive, the requested time is calculated by referring to the offset value. If the time is earlier than the current time, the M-icon of the time is selected from the magnetic storage device 306. The image is read, and if it is in the future, the image is acquired after waiting for the time (process 1302).
[0093]
On the other hand, if the duration setting is zero, the data at the time when the button is pressed is acquired (process 1303).
Next, the CPU 301 displays the data obtained in this way on the monitor 308 (processing 1304, 1305, 1306).
Note that the display of the area 105 at this time is a description of name 2 in the box 508 of FIG.
These data are in-point information. That is, it is displayed and recorded on the monitor 308 and index information in the order of the in point and the out point.
[0094]
Next, the CPU 301 refers to the value of offset this time.
First, when the offset value is positive, monitoring is performed until the time, and data at the time is acquired (processing 1307).
If the offset value is negative, the M-icon image at the time is read from the magnetic storage device 306 (process 1309).
On the other hand, when the value of offset is zero, data at the time when the button is pressed is acquired (processing 1308).
[0095]
Thereafter, the CPU 301 executes processes 1310, 1311, and 1312 for displaying the obtained data on the operation window 100.
Here, when offset = 0 and duration = 0, both the in point and the out point have the same time.
[0096]
Finally, a case where the out_out type button is pressed and the processing proceeds to processing 1105 will be described with reference to FIG.
In this case, first, the offset value is referred to (process 1401).
Next, as in the other modes, if the offset value is positive, monitoring is performed up to the time and data at the time is acquired (process 1402).
If the offset value is negative, an M-icon image at the time is acquired from the magnetic storage device 306 (process 1404).
On the other hand, when the offset value is zero, data at the time when the button is pressed is acquired (process 1403).
[0097]
Next, the CPU 301 checks whether or not there is an input point having an out point attribute before the time when the button is pressed (processing 1405).
If the out point exists, the image of the M-icon displayed on the operation window 100 on the monitor 308 is replaced with the currently acquired image (process 1406), and the time and name are also replaced with the current information. Replace (processing 1407, processing 1408).
[0098]
On the other hand, if there is no out point in the past, the attribute of the out_out point acquired this time is changed to out (1409).
Thereafter, each data is displayed on the operation window 100 on the monitor 308 (processes 1410, 1411, 1412).
[0099]
Next, returning to the description of FIG. 4, after the above-described monitor display processing 408, the CPU 301 outputs index information this time (processing 409).
An example of the contents of the index information at this time is shown in FIG.
In FIG. 15, each input frame is divided by No = n (n: 1, 2, 3,...). For example, when No = 1 of 1500, a frame type 1501 and a name 1502 are included therein. Time 1503, frame No. 1504, and the like are described. Note that the numerical values and the like described here are for explanation and have no relation to actual data.
[0100]
The output destination at this time may be the magnetic storage device 306 or another device connected via a network.
Similarly, index information is also described for the frames detected by the image recognition (process 411).
The above operations are repeated until the end button 107 is pressed (processing 410), thereby sequentially executing index creation work.
[0101]
Next, the automatic detection mode by selecting the automatic detection button 201 shown in the mode selection panel 200 of FIG. 2 will be described.
In this automatic detection mode, a feature of a video input in advance is detected, and when the frame of an image having the feature is input to the moving image editing apparatus 300, the frame or the feature appears. This is a mode in which a program based on a predetermined processing algorithm created so as to indicate a plurality of frames is executed, and information on in and out points is automatically added.
[0102]
If the automatic detection button 201 is pressed in the mode selection panel 200 of FIG. 2, the mode selection in the process 401 is configured to be the automatic detection mode in FIG.
Then, at this time, the process proceeds to processing 411. As a result, in addition to the processing in the manual index mode, automatic index creation processing is performed by the above-described processing algorithm.
[0103]
Here, the feature of the video input in advance is, for example, an image at the time of scoring in a sports program, an image at the time of switching scenes, etc. Therefore, as a means for detecting the feature of this video, for example, an image There is a means for detecting an image change point by a recognition process.
As this means, for example, as disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2-184181, the illuminance, volume, color tone, etc. of the moving image are analyzed, and a portion where these changes are significant is changed in the cut image. A technique for detecting points may be used, and therefore a detailed description is omitted.
[0104]
Finally, the editing method will be described.
When the edit button 201 is pressed on the mode selection panel 200 of FIG. 2, an editing panel 1600 shown in FIG. 16 is displayed.
Although details are omitted, the editing panel 1600 indicates a state in which data is read by specifying an editing target with the open button 1603.
[0105]
The editing procedure using the editing panel 1600 is to click the image display area 103 using the mouse 309, select an arbitrary image 103, and then press the delete button 1605 and the add button 1606. , This can be deleted and added arbitrarily.
[0106]
The editing panel 1600 is configured such that when an image is selected, the attribute of the image is displayed in an area 1601, and here, it is indicated as an in point. To change this attribute, simply click on another attribute with the mouse.
[0107]
Next, the comment written in the area 105 can be written and rewritten by designating the area directly with the mouse and inputting a new character from the keyboard.
Furthermore, by arbitrarily selecting an image displayed in the area 103 and pressing a preview button 1607, a preview panel 1700 is displayed in a window as shown in FIG.
[0108]
In the preview panel 1700, a full-size image stored in the magnetic storage device 306, for example, an image composed of 307200 (= 640 × 480) pixels in the case of an NTSC signal, is displayed in the area 1701. Various buttons are displayed below the area 1701.
[0109]
In view of this, it is configured so that it can be played back at any time before and after by pressing a button below these areas 1701. Therefore, the operator can view the image displayed in this area 1701 while viewing the image. The input point can be arbitrarily changed by pressing the SET button 1702 at a desired frame.
[0110]
In the operation window 100 in FIG. 1 and the editing panel 1600 in FIG. 16, only six areas 103 are displayed. To display the preceding and following areas, the slider shown in 106 is used. Just operate.
[0111]

[0112]
As a result, the screen of the operation window 100 shown in FIG. 1 is displayed on the monitor 308 (see processing 405), the currently input video is displayed in the area 101, and the area 102 described with reference to FIG. Various button groups 109 created by the processing are displayed.
[0113]
When the start button 108 is pressed (processing 1804), recording of video data to the magnetic storage device 306 is started. In processing 1805, it is determined whether or not processing is completed, and then the processing proceeds to processing 1806, where the operator edits points. Input operation, that is, an operation of depressing a predetermined button 102 at a predetermined time point while viewing an image displayed in the area 101, thereby selecting a type.
[0114]
Then, according to the selected type, each process, that is, a process according to any one of the flowcharts of FIGS. 11 to 14 is executed (process 1807).
For example, in the case where the in type in FIG. 11 is selected and the offset value is set to −3, the CPU 301 displays image data at a time that is 3 seconds after the button is pressed, as the magnetic storage device 306. The M-icon is displayed in the area 103, the time is displayed in the area 104, and the description of the button name 1 is displayed in the area 105.
[0115]
Then, the created index information is output (process 1808).
As described above, the output destination of the index information at this time is the magnetic storage device 306 or another device connected via a network, but other, for example, another computer reads via a network, You may make it utilize for the use (Video on demand: Video On demand) which controls VTR etc. and reproduces | regenerates an image | video.
[0116]
By repeating the above operation until the end button 107 is pressed (process 1805), index creation operations are sequentially executed, and finally a file name is assigned and stored (process 1809).
[0117]
Therefore, according to this embodiment, the operator can set an arbitrary offset for the setting of the in point and the out point, so that the operator can set the in point and the out point according to his / her skill and physical condition. Thus, by setting the offset value to a predetermined value, it is possible to compensate for the difference between the operation time and the time when the in point and the out point are actually set.
[0118]
As a result, according to this embodiment, even when a lot of events occur in the same scene (scene), such as a sports broadcast, and the subject's movement in the image is extremely intense, it is always appropriate. In-points and out-points can be set, and accurate identification information can be recorded easily and in a short time.
