Description

  The present invention relates to a recording device, a recording method, an editing device, an editing method, a playback device, a playback method, a program, and a recording medium, and more specifically to a multimedia content recording / editing / playback technology.

Conventionally, when editing video data recorded on a recording medium, an operation panel of the editing apparatus is used to repeat the operation of reproducing and checking the video data, and editing points (editing start point and editing point) An end point was searched for, and a cut video was extracted by a method of copying the video represented by the editing point to a recording device for recording.
By using such an editing device, even a person who is unfamiliar with cut video editing work can easily perform video data editing work, although this work is particularly important, Since it was very difficult and troublesome, there was a problem in terms of ease of use.

As a method of inputting such editing points to the editing device, there is a method of dividing the video based on a point where the video signal has a large change and automatically inputting it as a new editing point, so that the video to be cut can be easily recorded. I was able to.
When this change point is used, if the change point occurs frequently, there is a problem that the cut image becomes too small and the editing work becomes difficult after all.

Further, in the technique of Patent Document 1, a mark for identifying a good scene at the time of recording by the interviewer himself pressing a predetermined button while shooting a video material using a camera-integrated VTR at the interview site. Is recorded on videotape.
When editing this videotape, search for the mark while playing the videotape, cue up to the frame with this mark, and the editing operator looks at the video before and after the cueed up frame and edits the videotape. Determine the starting point and editing end point. By performing this operation on each mark, it is possible to perform rough editing by a very simple method compared to a conventional editing apparatus.

In the technique of Patent Document 2, the time code of the mark of Patent Document 1 is recorded in a memory chip of a file label attached to a video cassette. At the time of editing, a list of mark time codes stored in the memory chip is transferred to the editing apparatus.
The editing device acquires a still image corresponding to the time code of this list and displays it together with the list, and the editing operator determines the editing start point and editing end point while displaying the video corresponding to this still image. ing. As a result, it becomes easy to specify a good scene using the mark, and the editing operation can be performed efficiently.

  On the other hand, when the viewer tries to find the scene he / she wants to watch in the video, it takes time to find the scene he / she wants to watch because the viewer has repeatedly performed fast-forward and fast-rewind operations during video playback. There was a problem. For example, when playing a video image of a baseball game, if the viewer wants to see only the scene of the home run, it is necessary to search for the scene that the viewer wants to see by fast-forwarding or the like. Such an operation is troublesome for the viewer and wastes time. Furthermore, when searching for a scene to be viewed by fast-forward / rewind operation, an important scene is missed.

On the other hand, in the technique of Patent Document 3, a time bar corresponding to the time axis of the video image is displayed on the screen. An icon indicating the start position of the event scene, which is a characteristic scene in the video, is displayed on the time bar. When the viewer operates the remote controller and selects a desired icon, video playback is started from the start position of the event scene corresponding to the selected icon. Thereby, it is possible to jump and reproduce the scene that the viewer wants to see easily and accurately.

In addition, each time the marker recording button is pressed, marker data M1, M2,. As described above, there is a case where no marker recording operation is performed in one shooting, or a plurality of marker recording operations are performed.

  Next, the marker recording operation in the second case will be described with reference to the flowchart of FIG.

First, the recording device 10 is set to the moving image shooting mode (step S11).
When the recording device 10 is set to the moving image photographing mode, the photographing unit 11 starts photographing the subject, and the photographed video is recorded on the recording medium 15 by the video data recording unit 13 (step S12). If the photographer does not perform the marker recording operation and the recording of the video is continued and the capacity of the recording medium 15 is full, only the video recording after the most recent predetermined time (which can be changed as appropriate) is left, and the oldest one is in order. Delete and record new videos sequentially.

  If the photographer performs a marker recording operation at the time when the photographer thinks that it is an important scene during shooting, the marker recording means 14 records the time stamp when the marker recording operation is performed on the recording medium 15 as meta information data. (Step S13). Here, after the start of video recording, when the first marker recording button is pressed, video data before a predetermined time (which can be changed as appropriate) is deleted, and video after that is left.

  This marker recording operation is executed by pressing a marker recording button assigned to a button associated with the digital camera, such as a shutter button or a function button, in the input unit 12 of the recording apparatus 10. As in the first case, the marker recording operation can also be performed from a remote location using one or more remote controllers.

The photographer presses the marker recording button as many times as necessary to record the marker data, and the shooting and marker recording is performed until the shooting end button is pressed or the moving image shooting mode is ended or the capacity of the recording medium 15 is full. An operation is performed (NO in steps S12, S13, and S14).
When shooting is completed (YES in step S14), video recording by the video data recording unit 13 is ended.

  FIG. 6 schematically shows the contents of the recording medium 15 storing the video imaged by the second method. The recording medium 15 records the video recorded during the video shooting mode, and stores marker data M1, M2,... Mm each time the marker recording button is pressed.

  Next, editing for specifying the range of important scenes based on the marker data recorded by any of the above-described methods will be described.

(B) Editing Recorded Data First, moving image / still image / sound / sound digital data and marker data to be edited must be taken into the editing device 20.
The data to be edited is the data recorded on the recording medium 15 of the recording apparatus 10 or the data already stored in the editing apparatus 20.
As described above, the recording device 10 and the editing device 20 are connected to the recording device 10 by wire, infrared, or wireless connection and transferred to the editing device 20. In the recording device 10 such as a network camera, the captured video or the collected sound / sound and marker data has already been directly transferred to the editing device 20.

Next, an operation after data to be edited and marker data have been transferred to the editing apparatus 20 according to the present embodiment will be described.
FIG. 7 is a block diagram showing a functional configuration of the editing apparatus 20 according to the present embodiment. In FIG. 7, the editing apparatus 20 includes a content file group 71, a data list creation unit 72, a data list storage unit 73, and an editing operation unit. 74, a range adjusting means 75, and a data reproducing means 76 are included.

When the editing device 20 is activated, the data list creation means 72 is operated.
The content file group 71 has one piece of digital data (moving image, still image, sound, sound, etc.) and marker data (markers marked as important scenes in moving images, sound / sound), respectively. Each file is stored as a file.

The data list creation means 72 reads each file of the content file group 71, determines the type of the file, and in the case of a moving image or sound / sound, reads the marker data written as meta information data to read the data list Is written in the data list storage means 73.
The data list storage means 73 records the following data for one digital data (see FIG. 8).

File location: The name of the file that holds the content data or the location where the file is located.
Type: The type of data in this file (for example, distinction between moving images, still images, sound / sound)
Key frame information: When the type of data is video or sound / sound, the time stamp of the frame (referred to as key frame) at the time when the marker is added as an important scene. If the data type is still image, the date this data was created.
Start point: Distance from key frame (expressed in hours: minutes: seconds: frames).
End point: distance from key frame (expressed in hours: minutes: seconds: frames).

When the data list is created, the editing operation means 74 is activated, and a data list as shown in FIG. 9 is first displayed. The data list screen 80 shown in FIG. 9 includes a data list display area 81, a range adjustment area 82, and a reproduction display area 83.
As shown in FIG. 10, the data list display area 81 represents a thumbnail of the image itself when the data is a still image, and a key frame with a marker that indicates an important scene when the data is a moving image. A list of thumbnails of images, or thumbnails assigned as appropriate when the data is sound / sound, is displayed. Below each thumbnail, a data type 84, a file name 85, and a creation date 86 (or a time stamp of a key frame) are displayed. When the data type is a moving image or sound / sound, an icon 87 (or a character string) for performing range adjustment is displayed.
In the example of FIG. 10, a data list including three still image data, five moving image data, and one sound / audio data is displayed.

If the data is a moving image or sound / sound, clicking the icon 87 activates the range adjusting means 75 and displays an instruction screen as shown in FIG.
In FIG. 11, the left end 94 of the semicircle indicates the recording start position of one data, and the right end 98 indicates the recording end position. In this semicircle, the time stamp position of the key frame is indicated by a black triangle 96, and the start point and end point of an important scene including the key frame are indicated by a start point 95 and an end point 97, respectively.

A field 91 indicates a distance (minute: second: frame) from the key frame position 96 of the start point 95, and a field 92 indicates a distance (minute: second: frame) from the key frame position 96 of the end point 97. ). The initial values of these distances are displayed as a start point at −m seconds from the key frame and as an end point at + n seconds from the key frame (see FIG. 12). The initial values M and N can be changed as appropriate. For example, m = n = 5 is set.
Further, by rotating the dial 90, the start point 95 of an important scene can be adjusted. By rotating the dial 93, the end point 97 of the important scene can be adjusted.
This range can also be adjusted by inputting the distance directly into the fields 91 and 92.
When the range by dial adjustment or numerical value input to the field is adjusted, the start point 95 and the end point 97 are also changed in conjunction with each other, and the range before and after the key frame position can be understood intuitively.

  Further, in order to confirm whether or not the range set during the adjustment is correct, when the reproduction button 99 is pressed, the data reproduction means 76 is activated and the content of the reproduced data is displayed in the reproduction display area 83. When the data is a moving image, a moving image is displayed, or in the case of sound / sound, the sound / sound is reproduced and the reproduction status is displayed.

  When the range specified by the editor as described above exceeds the range of the entire data originally acquired, the start point or end point of the data is set as the start point or end point of the range. For example, if the key frame position is 10 seconds after the start of video shooting, even if the start point is set to −15 seconds with reference to this key frame, the start point is set to −10 seconds.

  Finally, the editing operation means 74 stores the start point and end point of the important scene set by this range adjustment as the start point and end point of the key frame.

  The display used for specifying the range is not a dial as described above, but a display such as a slider that allows easy range setting can be applied.

Furthermore, by copying and pasting the digital data displayed in the data list display area 81, the corresponding digital data can be pasted on word processing software, presentation creation software, or album creation software. At this time, the whole digital data and meta information data (stored in the data list storage means 73) are pasted.
For example, as shown in FIG. 13, when the range of the key frame Key1 is (−1 to +1) and the range of the key frame Key2 is (−2 to +1) for the video data 100, the slide of the PPT The video 102 pasted on 101 is the video data 100 and meta information data (time stamp of Key1, distance between start point and end point from Key1). The video 104 pasted on the PPT slide 103 is the video data 100 and meta information data (Key2 time stamp, distance between start point and end point from Key2).
Furthermore, after pasting on word processing software, presentation creation software, or album creation software, starting the pasted data, a range adjustment screen is displayed, and the range can be readjusted.

(C) Reproduction of Pasted Content Next, a reproduction apparatus that reproduces content attached to a document, an album, or the like will be described. In the following description, content attached to a document for presentation will be described as an example, but other documents and albums can be handled in the same manner.
FIG. 14 is a block diagram showing a configuration of a playback apparatus when a presentation is executed using a presentation document created as described above, for example, a plurality of slides.

If a slide with one or more images or sound / audio pasted is displayed during the presentation, and if the presenter does not perform any operation, the playback means is activated and the pasted video or sound is displayed.・ Sound is played continuously in sequence. At this time, if the video or sound / audio data includes a key frame, the video / sound / audio in the range specified by the meta information data of this key frame (time stamp of key frame, start point and end point). Extract and play audio.
When one slide is finished and the “next” operation is performed by clicking the mouse or keying on the keyboard, the next slide is activated, and the reproduction of the first video or sound / audio pasted is started. In this way, the presentation is executed by activating the slides one after another.

Also, if there are three video clips each containing a key frame in the video data as shown in FIG. 15, if the presenter performs the “next” operation while playing these three video clips, the next Jump to the start point of the video clip and continue playback.
For example, if the “next” operation is performed at the fifth frame during playback of the video clip 1 consisting of 6 frames, the 5th and 6th frames of the video clip 1 are skipped and the next video clip 2 starts from the first frame. Start playback.
Therefore, if the “next” operation is not performed when it is desired to show the video longer, and the “next” operation is frequently performed when the video is desired to be shown shorter, the length of the video can be adjusted during the presentation.
