DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for retrieving video information from a remote place using a personal computer terminal and the Internet. In particular, it is possible to easily find a video that meets a request from an enormous amount of captured video. The present invention relates to a video editing support system.

[0002]

2. Description of the Related Art In general, a video photographer, such as a video, creates and uses a cut schedule in order to find a cut necessary for video editing. Video editors use the information in the cut schedule to search for the required video from the recorded video based on the tape number and time code written there, but it is difficult to determine the content using the cut schedule alone. It takes a long time to repeat the work of rewinding the taken tape and checking the video contents many times.

[0003] Even if the cut schedule is registered in a computer and converted into data, it is unavoidable to repeat the work of rewinding the taken tape and checking the video contents, and it requires a lot of time. Does not change. That is, the video editor cannot determine the edited video without looking at the motion or image of the video. In order to do this, you must go to the location where the video is stored.

[0004]

The images are increasing year by year with the help of the recorded program boom of television. There are many scenes on one side that cannot be taken again due to destruction of nature. Even if it is desired to re-edit a previously shot video when editing a program or creating a notification video, the conventional method takes too much time. Valuable images are often buried because they take too much time to reuse. In addition, there is a demand for a method in which the user has to go to a storage location in order to search for an image, and can save the trouble.
On the other hand, even if the photographer or video manager organizes the shot video using cut schedules, etc., the video content cannot be expressed only with textual information, so the video cut content can be easily viewed, It is effective to use a system that can easily update the system.

[0005] There is also a video rental business that lends many videos already taken. If you go there, you can select the image of the image you want and dub the editing image, and borrow it, but here also there is a waiting time until you retrieve the image from the recorded tape. Since it is not always possible to meet the image exactly as expected in one shot, rewinding the tape and watching the image takes a lot of time.
Also, since the person searching for the video has to go there, it takes a long time to move. The lending side also prosperes the labor price and waiting time to the lending price, so the fee increases.

[0006] With the spread of personal computers, video images can be easily edited not only by professionals but also by ordinary people. On the Internet, the popularity of still images to video images is increasing. Video images can be easily searched not only in professionals but also in the general consumer market, and if the desired images can be distributed, the market will be activated.

Accordingly, the present invention provides a video editing support system that can support video editing, thereby enabling video users, video photographers, and video rental companies to reduce a lot of wasted time and activate video reuse. The purpose is to provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A video editing support system according to the present invention will be described below with reference to the drawings.

The video editing support system according to the present embodiment is installed in a video editor, a photographer, or a video lender, and as shown in FIG. 1, a cut video storage unit 1-2 and a shooting information storage unit 1-3. , Display section 1-4, operation section 1-6
And a dubbing output unit 1-5, an external communication unit 1-7, a Web server 1-8 as required, and a bus 1-9 connecting these units.

Here, each part will be described in order. The cut image storage unit 1-2 is composed of a storage device such as a hard disk, and stores images in shot cut units in a compressed file format, and each file is assigned a unique number. Since the cut image is a preview image for confirming the motion and the content of the image, it is important to emphasize the ease of handling over the image quality. Therefore, it is not necessary to set the image size to a full screen, and a small size that does not impose a burden on transmission is preferable. The screen size and the compression format can be determined from the relationship between the transmission speed and the image quality, and a size and a file format that are easy to handle can be selected, and can have audio information.

The photographing information storage section stores various kinds of information relating to photographing information, and is also used as a search keyword. A number corresponding to the unique number of each file stored in the cut image storage unit is stored as one of the shooting information. A unique number is also set for the original data video, and stored together with the time code of the cut video stored in the cut video storage unit 1-2 as the same database. Other specific examples of the photographing information items include a photographing place, a photographer name, a subject name, a photographing time, weather, camera work, and the like.

The display section 1-4 comprises a CRT monitor or a liquid crystal monitor, and displays search results and images. The operation unit 1-6 includes a keyboard, a mouse, and the like, and is operated to input search conditions. The dubbing output unit records digital video such as a digital video deck on a recording medium such as a magnetic tape.

The external communication unit 1-6 comprises a modem or a network interface, and is connected to an external device via a public line, an optical fiber, a LAN, or the like.
For example, communication is performed on the Internet. Web
The server 1-18 is connected to the internal network and can be used for Internet access. By storing the data of the cut image storage unit 1-2 and the photographing information storage unit 1-3 in the Web server 1-8, It is possible to provide a system capable of searching and displaying cut images from a remote place using a network such as the Internet.

The control unit is a CPU of the computer, and mainly controls the operation of the present system. The operation control performed by the control unit 1-1 includes, for example, information extraction control from the photographing information storage unit 1-3 and cut image storage unit 1-2, and display control on the display unit.

Here, the operation control performed by the control unit 1-1 will be described with reference to the flowchart of FIG. The control unit 1-1 of the present system first displays a search item on a menu screen (2-2) and requests designation of a search condition (2-3). This specification can be performed by operating the operation unit 1-6. In this case, a pull-down format or a key input format may be used.

When a search item is designated, the control unit 1-1 retrieves and retrieves the data from the data stored in the photography information storage unit using the retrieval item as a retrieval condition, and obtains the unique information of the cut image file of the photography information data. A cut video file corresponding to the number is retrieved and retrieved from the cut video storage unit, and the characters of the shooting information and the thumbnail (small image) of the cut video are displayed on the display unit 1-4 (2-4).

At this time, the control unit 1-1 requests the next designation for the search result. Specify display of cut image (2-
5) Then, the control unit 1-1 decompresses the compressed file of the cut image and displays it on the display unit. If the video is satisfactory as the requested video by viewing the preview video, the editing video is dubbed (2-12) from the original data video by specifying the number and time code of the original data video of the video. I can do things. At this time, if the system is performing remote operation from the Internet using a Web server, it is possible to request dubbing or order an editing video in a video lending business. In this case, the dubbed video will generally be delivered to the editor by physical distribution. Although there is a time lag until it arrives, the editor can obtain other necessary images from the preview video and can proceed to other tasks.

In response to the request from the control unit 1-1 in the search result display (2-4), when the input of photographing information is designated (2-6), the control unit 1-1 displays a photographing information input screen (2). −
8). On this screen, you can change or add shooting information,
New video data can also be input. When the input content is determined, when the input determination instruction (2-10) is issued, the control unit 1-1 updates the imaging information (2-13). When remote control is performed using a Web server, a user can rewrite or add shooting information data from anywhere on the network. At this time, the data change operation can be managed with a password or the like.

[0021]

As described above, according to the video editing support system of the present invention, it is possible to quickly extract a video having a content that meets the user's request from a huge amount of video. You can see the essential images and movements of the subject. Especially professional editing requires accurate timecode. Being able to easily link to the dubbing operation for editing from the time code and the unique number of the original data video greatly increases the efficiency, and the editing operator can save time in the original editing work.

In professional editing work, dubbing images must be of high quality, so there is a strong demand for dubbing from original images. I do not like to move much because the management of the original video is very careful. By locating the Web server of the video editing support system of the present invention on the management side of the original video, the user can search for the video by remote control, and there is almost no trouble for the administrator to determine the video. The registration of the shooting information can be done in the same way as the cut table creation that the video manager has done so far, and if the cut video file can be registered, the detailed registration of the shooting information will be done by the photographer Is convenient because it may work remotely.

The video editing support system of the present invention is also effective in a video lending business (video library). Both lenders and borrowers can save a lot of time and effort. Therefore, the price can be set at a low price, and above all, the market can be developed for the general public.
