Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material video database system, and more particularly, to the production of video works for a limited audience, such as news programs such as business news and package software of the news programs. The present invention relates to a material video database system for accumulating a plurality of video materials, which is suitable for use in, to configure a database, and for searching video materials that meet a purpose from the video materials.

[0002]

2. Description of the Related Art Conventionally, the production of images such as news programs has been
It was carried out for the purpose of distribution to an unspecified large number of viewers in mass media such as the broadcasting industry.

[0003] In the broadcasting industry, the above-mentioned video programs are usually distributed using ground stations or broadcasting satellites.

However, today, the demand for video distribution to a limited number of objects has increased, and there has been a demand for distributing business video such as business news programs using communication satellites.

This business image has the following features.

That is, this business video is delivered not to the mass media intended for an unspecified large number of viewers but to only a specific contractor using a communication satellite. Therefore, it is necessary to reduce the production cost.

Further, it is characterized by the instant collection and distribution of images by the communication satellite, and it is necessary to immediately collect the related material images and edit the transmission file. Therefore, it is important to reduce the manufacturing time.

[0008] Furthermore, the viewers are limited businessmen, and it is required to provide more specialized information for problem solving. Therefore, it is necessary to collect so-called horizontal information, which serves as a reference related to new information, and provide information with a wide range.

In order to produce a video program such as the above-mentioned business video, a large amount and various types of video data such as still image data, moving image data, and audio data are required.

A still image is a still image, and its recording medium includes a photo original. In addition, a moving image is a moving image produced by sequentially displaying successive frames (frames), and its recording medium includes a video tape and a movie film. In addition, the sound mainly has a background sound of a moving image, and the recording medium thereof has a video tape or an audio tape similar to the moving image.

Conventionally, in the production of video programs, still image data, moving image data, and audio data are recorded and collected each time they are produced. Moreover, even if data is stored, each data is stored independently of each other and retrieved separately.

For example, moving image data may be stored in a video tape library, and the moving image data may be searched by a title index.

The audio data is usually recorded together with the moving image data on the same medium (video tape, etc.) as the moving image data. Also, the voice data may be stored in a voice database dedicated to the voice data, if necessary. However, the audio data was not stored in association with the image data.

[0014]

Since one frame (frame) of the moving image data can be used as a still image, one frame of the moving image is also searched when searching for a still image. Searching for tops may also be desired.

However, conventionally, moving image data and still image data are separately stored, and when searching for each data together, it is necessary to perform the search for each still image and each moving image. I had to do similar searches multiple times. Therefore, there is a problem that the search is complicated and takes time.

Further, the voice data is stored in the same medium as the moving image data as described above, or is only stored in the voice database, and the voice (natural voice) is stored in the recording medium together with the moving image data. For example, voice data for narration, which is input from data or another input device, cannot be stored together with image data. Therefore, it is necessary to separately search the audio data and the moving image data, which is complicated.

Therefore, conventionally, there has been a problem that still image data, moving image data, and audio data as video materials cannot be easily and quickly retrieved.

Therefore, when producing a video program intended for a specific audience as described above, it is an obstacle to fulfilling the demands for reducing the number of producers, shortening the production time, and providing a wide range of information. Was there.

The present invention has been made to solve the above-mentioned conventional problems. Still image data and moving image data can be stored in a mixed manner, and audio data and other data can be associated with the image data. It is an object of the present invention to provide a material video database system capable of accumulating and storing still image data, moving image data and audio data easily and quickly.

[0020]

SUMMARY OF THE INVENTION The present invention is a database system for accumulating a plurality of video materials and retrieving a video material suitable for a purpose from the video materials, and a still image as the video material. Data, video data, and
The object is achieved by providing means for integrally accumulating voice data to form a database.

[0021]

In the present invention, a plurality of video materials are accumulated,
When retrieving a video material suitable for the purpose from among the materials, still image data, moving image data, and audio data as the video material are integrated to form a database.

According to the present invention, the video material used as the material for program production is mixed with still image data and moving image data,
Since these images can be integrated and stored in the database, it is possible to search in a short time by utilizing the management material of the video material. Therefore, it is possible to reduce the production cost, shorten the production time, and provide the video reference material for the production of the video program.

The distinction display 18A can distinguish, for example, a representative image of moving image data by a green frame and a representative image of still image data by a red frame.

Further, the selector 18F may be a keyboard common to or different from the numerical character input device 16D. Alternatively, a mouse can be used.

The database utilization unit 20 is provided with a video printer 20A for taking a hard copy of the image sent from the database management unit 10 side and a dot printer 20B for printing out image-related information. .. Although not shown, the database use unit 20 is provided with a voice synthesizer that generates voice-over voice by voice synthesis.

The terminal device 12 is provided with a second storage stage 24 for recording each processing program data and recording data when inputting or outputting image and audio data to and from the database management unit 10. Has been.

Since the database system has the above-mentioned functions, the image data and the like stored in the database and the recording medium have the following structure.

In the case of moving image data of a relatively long time, the moving image data is recorded in a recording medium and stored in a storage, and a reduced image of a representative image displayed on the search screen is stored in the first storage. It is recorded in the stage 10A in the form of digital data in order to improve the efficiency and speed of the search.

That is, the moving image is reproduced from the recording medium by the video device 14, and an image showing the content of the moving image or an arbitrary image is extracted by the frame buffer 14D as a representative image. Image data (constitutes a search screen) is created by reducing the extracted images so that they can be arranged in a grid pattern (for example, vertical 10 × horizontal 10), and the database management device 1 is stored as a file in the first storage 10A.
Record 0. On the recording medium on which the original moving image data is recorded, a label with a reference number is attached to the recording medium case and stored. The details of this search screen, creation, and search will be described later.

In the case of moving image data of a relatively short time,
It is reproduced by the video device 14A, and a necessary portion is recorded as an analog signal on the video disc 10B together with the sound. This enables high-speed search.

Still image data can be input corresponding to both the video signal (analog signal) input from the video device 16E and the still image signal digital signal input from the scanner 16B. Further, a reduced image of the representative image displayed on the search screen is recorded in the first storage stage 10A in the form of digital data so that the search can be made efficient and speedy. The analog still image data is recorded on the video disk 10B and is also stored in the frame buffer 16F, and is reduced in size so that it can be arranged in a grid pattern (for example, about 10 vertical by 10 horizontal) on the screen (search screen). The first storage stage 10A
It is stored in the database management device 10 as a file. Further, the digital still image data input from the scanner 16B or the like is subjected to pixel density conversion by the pixel density converter 16C to be NTSC digital image data, and the data is recorded in the first storage stage 10A and is analogized. Similar to the still image data, image data reduced so as to be arranged in a grid is created and stored in the database management device 10 as a file in the first storage 10A.
Further, digital still image data input from the scanner 16B or the like can be input to the first frame buffer 14D to be converted into analog data and recorded on the video disk 10B. As described above, if the still image data is recorded on the video disk 10 in the form of analog data, the data amount can be reduced as compared with the digital data, the reproduction time is short, and the handling is easy.

Regarding the narration voice data among the voice data, a narration original describing the contents of a moving image or a still image is input from the word processor, for example, a character (character code) via the numerical character input device 16D or the data exchanger 16A. Data) enter. Also, the character code data is converted into phonetic code data and stored. With this phonetic code data, the voice synthesizer can reproduce the narration voice. In this case, the character code data is stored for use in displaying a telop and the like.

Regarding the natural voice data, the natural voice data is stored in the video disk 10B together with the moving image data. Further, when recording is necessary when the data is not input to the video disc 10B, it can be converted into an ADPCM file and can be converted into a file in the first storage stage 10A.

In addition, regarding still image data and moving image data, video-related information, that is, management information such as a photographer and a shooting date, and related information for clarifying the original / background of the video, each item is a maximum of 200 characters. Enter the degree and make it available when searching. In the case of moving image data, a time code or the like is automatically recorded so that it can be called up quickly.

Further, a keyword is added to the image data so as to be used for the convenience of text / search. For the keyword, select a free keyword consisting of any word that directly expresses the video, or a controlled keyword that is selected from pre-selected and classified according to its own classification, or enter word proset And add it to the image data.

As described above, in the database system of the embodiment, still image data, moving image data, natural voice data and narration voice data are integrated and stored as a database.

FIG. 4 shows an apparatus configuration as seen from the function of searching the database system by creating a search screen from moving image data. The image input function shown in FIG.
The moving image input unit 14 and the database management device 10 correspond, and the image search function corresponds to the database management device 10 and the database search unit 18.

That is, the image input function is performed by each frame reproducing unit 3.
0, a reduced screen creation unit 32, and a reduced screen storage unit 34.

Each frame reproducing section 30 reproduces an image of each frame of the moving image data and creates and records a search screen composed of a reduced image, and is mainly used for the video equipment 14A.
And a frame buffer 14D. or,
The reduced image creating unit 32 is for creating a reduced image to be displayed on the search screen, and mainly includes the pixel density converter 16C. The reduced screen storage unit 34 is for storing the created reduced image, and mainly includes the first storage stage 10A.

The image search function is used for searching on the search screen and displaying the image in the screen like a moving image. Mainly, the storage unit 34 and the reduced image still image-like display unit 1 are provided.
8B, a moving image display section 18C, a bitmap display 18E, and a selection means 18F. The contents of the display section 18B and the like have been described above, and will be omitted.

In the search screen, the display screen of the bit map display 18E is divided into about 10 × 10 (or 8 × 10), and reduced images of representative images of moving image data and still image data are displayed on each divided screen. They are displayed in order.

That is, in the case of moving image data, a reduced image is created and accumulated in each frame or a frame (for example, 10 frames) at regular intervals, and it is continuously displayed (a moving image by the whole frame or the frame dropping). So that you can understand the video contents. At the time of this moving image display, the time code of the original image is displayed in real time. As mentioned above,
If the moving image is displayed by dropping the frame, the content of the moving image data can be grasped in a short time.

In the case of still image data, the image itself is the representative image, so a reduced image of the still image data is displayed on the search screen.

The procedure for creating a reduced image for displaying a moving image by the above-mentioned drop-off is shown in FIG. In FIG. 5, steps 101 to 103 are performed by the operation of the image input person.

First, the video device 14A reproduces a recording medium such as a video tape to search for the beginning and the end of the moving image, and records the time code thereof (step 10).
1).

Next, a frame interval for forming a reduced image for moving image display on the search screen is determined (step 102).

Next, the time code of the first and last parts of the moving image and the frame interval for producing the reduced image are set to the reduced image creating section 3
Set to 2 (step 103).

From this point onward, the procedure is automatically advanced.

That is, the recording medium is reproduced (still) at the position of the first time code (step 104).

Next, the image being reproduced as a still image is input to the frame buffer 14D and, for example, horizontal 768 × vertical 480.
The dots (24-bit full-color image) are converted into digital data, and then the pixel density converter 16C thins out to, for example, horizontal 128 × vertical 96 dots (limited color of 8 bits) to create a reduced image (step 105).

Then, the created reduced image is stored in the first storage stage 10A (step 106).

Next, it is judged whether or not the frame at the position where the frame interval for producing a reduced image is added to the frame at the position where the still image is currently reproduced exceeds the last frame of the moving image data (step). 107). If it exceeds, creation of the reduced image for displaying the search screen ends (step 10).
8).

On the other hand, if it does not exceed the limit, the recording medium is fast-forwarded by a frame interval for producing a reduced image, and a still image is reproduced at that position (step 109).

Then, the process returns to step 105 to restart the production of the reduced image.

By the way, the reduced image of the still image data is created by thinning out the still image data by the pixel density converter 16C. Created reduced image (this is the representative image)
Is stored in the first storage stage 10A.

Further, when displayed on the search screen, the reduced images (representative images) of the still image and the moving image can be arranged arbitrarily. In this case, the distinction display 18A identifies the moving image and the still image. For example, a moving image should be surrounded by a green frame, and a still image should be surrounded by a red frame.

Next, the search of the above database will be described. First, the search on the search screen will be described.

In this search, when the operator designates a classification item (culture, sports, incident, etc.), each moving image data included in the classification is selected. Next, a reduced image of each representative image of each image data is, for example, 10 × 1.
The search screens arranged in a grid pattern of about 0 are displayed on the screen of the bitmap display 18E.

FIG. 6 shows a display example of the search screen.

In this case, when the reduced images cannot be arranged on the screen, the screen can be scrolled up (scroll up) or scrolled down (scroll down), the frame display, the attribute display, and the search end instruction can be given. ing. The contents of this scroll-up will be described later in detail.

FIG. 7 shows an example of a state in which a representative image for moving image display is selected.

As described above, from the displayed reduced images (representative images), if it is desired to know the details of the reduced images (representative images), the representative image to be displayed as a moving image is displayed as shown in FIG. Select with the cursor.

When the cursor is selected, all the frames or the reduced images of the frames are successively displayed at the position of the selected image, as shown in FIG. 8, and a moving image is displayed. With this moving image display, it is possible to easily understand what kind of motion the moving image data shows. In addition,
If you select the image with the cursor during moving image display, the moving image display will stop.

Also, since the number of representative images is large, if all of the images are not displayed, selecting the icon "scroll up" with the cursor moves the entire displayed image upward by one column, By this movement, another image which has not been displayed until now is displayed in a horizontal row below the screen. Further, when the icon "scroll down" is selected with the cursor, the entire displayed image is moved downward by one column, and the image that has disappeared from the screen is displayed again by scrolling up. The directions of scrolling up and scrolling down are as shown in FIG.

Further, when the cursor "icon" is selected with the cursor and then the representative image to be displayed with the cursor is selected with the cursor, each reduced image frame accumulated for moving image display of the selected representative image is displayed. The reduced images of all the frames that have been read and accumulated are displayed in order from the left side of the screen. The display direction is as shown in FIG. By this frame display, it is possible to know in more detail how the subject in the moving image data is moving. In addition to displaying all the frames, the reduced image can be displayed by thinning out a certain amount.

When the portion "display attribute" is selected with the cursor and then the representative image whose attribute is to be displayed is selected with the cursor, the storage location of the original moving image corresponding to the representative image, the shooting date, the photographer, etc. Attribute information is displayed on the screen.

In this database system, in addition to the search by the reduced image on the search screen as described above,
You can do the following searches:

That is, it is a search for each classified field. In this search, the images are classified according to the data field and are extracted for each field. The classification has a hierarchical structure, and each item can be further subdivided into about 10 items.

Further, it is possible to search by management information. This search is performed using video management information such as the photographer and the shooting date. A range can be specified for the search on the display screen.

It is also possible to search by free keywords.

In this search, a display image is selected using a keyword extracted from a sentence such as a scenario and added to a video.

It is also possible to search by control keywords.

In this search, a candidate image is selected by using a keyword that has been selected in advance and is added to the video.

It is possible to search by a keyword network.

This keyword network defines the relationships between the keywords while weighting them so that image data closely related to the specified keywords can be extracted at the same time during the search. In addition, the videos can be arranged in the order of relevance to the designated keyword.

Also, a combination of searches can be performed.

That is, the management information, the free keyword, the controlled keyword, and each field-specific search can be used in combination with each other in addition to inputting the AND / OR operator.

Also, metacharacters can be used.

A part of a word can be designated as a metacharacter, and by using the metacharacter as a search key, it is possible to perform a wide range search by a partial position of a keyword. For example, the meta character designation is ski ○○○ (○
For example, ski wear and ski boots are applicable if XX is a free character.

It should be noted that it is possible to output a hard copy of an image which is a candidate for retrieval by the video printer 20A and output related information by the dot printer 20B.

As described above, the still image data, the moving image data, the audio data, etc. obtained by the search are the database input / search / use terminals in response to the output request of the moving image data stored in the video disc 10B. It can be sent to the video equipment 14A of the device 12. In this case, the voice can also be transmitted. When the original moving image data on the search screen is recorded on the recording medium in the storage, the recording medium for the moving image can be pulled out from the storage with the tape management number output to the dot printer.
Also, when setting the tape in the video device 14A,
Cue can be done.

Further, it is possible to call a still image and take a hard copy output. At this time, the database management unit 1
The still image sent from the 0 side is the video printer 20A.
The color hard copy can be output with. Related narration is done by a speech synthesizer and natural speech is AD
It is reproduced into an audio signal by the PCM decoder and output.

In the above-described embodiment, since moving image data can be searched in addition to searching for still image data, it is possible to collectively perform the searches that have been duplicated for each data in the past, and to perform a quick search. Is.

Further, although there is a possibility that the contents other than the frame (frame) other than the representative image may be overlooked in the search using only the representative image, in the present embodiment, since the whole frame or the frame is displayed like a moving image. There is no such oversight, and moreover,
It is possible to properly understand the movement of a moving image.

In addition, the contents of the moving image can be grasped in a relatively short time by the search by the drop-down display. Therefore, conventionally, it took a long time to reproduce all images, but the time can be greatly shortened.

In the above embodiment, the database system having a detailed configuration as shown in FIG. 3 is exemplified.
The database system of the present invention is not limited to the configuration of FIG. 3 as long as it is the database system corresponding to the concept of FIG. 1 or 2. If the database system corresponds to FIG. The present invention is also applied to the database system having the above configuration.
