Alternatively, an image recording / reproducing device has been developed. Since these storage media have a large capacity, they can store video for several hours, but in order to use the storage media more effectively, images are stored in the storage media after being compressed. There is also.

The image information stored in these storage media is reproduced by a single image reproducing device, connected to a personal computer and reproduced on a personal computer, or connected to a network and reproduced on a workstation. I am. When reproducing the image information stored in the storage medium, the user retrieves the image information based on the character information such as the title name of the image information and reproduces the desired image.

[0004]

As described above, since the image information to be reproduced is conventionally searched based on the character information such as the title name, the image information can be searched for.
When trying to search for a specific screen (scene) in the selected image information, it is necessary to play the image information from the beginning by fast-forwarding, for example, to find the desired specific screen, which takes time and trouble. there were. Further, if the user accidentally misses the desired screen during the reproduction for the search, there is a problem that the image information must be reproduced again from the beginning and the search work must be redone.

An object of the present invention is to eliminate the above-mentioned problems of the prior art, to easily grasp the contents of the image without replaying the image from the beginning to the end, and interactively search and reproduce the image. Another object of the present invention is to provide a moving image search device capable of finding a desired video.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the drawings. Here, a moving image search from moving image encoded data compressed by MPEG1 (ISO / IEC 11172), which is an international standard method of moving image encoding, will be described. However, the present invention is a moving image compressed by the MPEG1 compression method. The search is not limited to images.

One embodiment of the present invention comprises a hard disk for storing video data, a reproduction board for reproducing compressed moving images, a PC (personal computer) having software built therein, a monitor and the like. In addition, an interactive operation is realized by using a pointing device such as a mouse.

FIG. 1 is a block diagram showing the function of this embodiment. The data storage unit 1 in the figure corresponds to the hard disk, and the data storage unit 1 stores genre selection screen information, video title selection screen information, various video files A, B, ..., Index files in advance. . The reproduction unit 2 decodes and reproduces the video file a, which is the compressed moving image read from the data storage unit 1, and corresponds to the reproduction board. The reproducing unit 2 sends the decoded video data b to the display data buffer 7.

The control unit 3 is composed of a CPU and the like, and corresponds to a PC containing the software. The screen display unit 4 displays the genre selection screen information, the video title selection screen information stored in the data storage unit 1, or the video file decoded by the reproduction unit. Also, various control buttons and the like are displayed. The operation input unit 5 corresponds to a pointing device such as a keyboard and a mouse.

When an image search instruction is given by an operation procedure from the operation input section 5 by the operator, the search processing section 6 designates a video file designated from various video files stored in the data storage section 1. c is retrieved, and a video scene is searched by a plurality of types of methods (a time search, a scene search, a similar image search described later, etc.). Search processing unit 6
When the index search described later is selected, the index file d in the data storage unit 1 is retrieved and the video file is searched using the index file d. The search processing unit 6 sends the screen information e of the search result to the reproducing unit 2, and also sends the information f associated with the search screen such as the screen time code to the display data buffer 7. The display data buffer 7 temporarily stores the data to be displayed on the screen display unit 4.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. 2 and the screen display of FIG.
First, as shown in step S1 in FIG. 2, it is assumed that video data is compression-encoded and stored in the data storage unit 1 classified by genre according to the content thereof. In step S2, when the operator starts up the application software of this system, the control section 3 reads the genre selection screen information from the data storage section 1 and transfers it to the display data buffer 7. As a result, the genre selection screen as shown in FIG. 3 is displayed on the screen display unit 4. The genre name is displayed by searching the directory name. In step S3, it is determined whether or not the genre of the video to be searched for and reproduced is selected from the genre selection screen. When the genre is selected, the process proceeds to step S4. This selection can be made by using a pointing device.

In step S4, the video title selection screen information is read from the data storage unit 1 and the video title selection screen as shown in FIG. 4 (a) or (b) is displayed. The genre selection screen information and the video title selection screen information have a file structure as shown in any of (a) to (c) of FIG. (a) and (b) show the file structure when displaying a title name by searching a directory, and (c) shows the file structure when displaying a title name using an identifier.

As shown in FIG. 4, the contents displayed on the video title selection screen include the title name of the video data, the representative screen, and the total time. As with the genre name, the title name is displayed by searching a directory in which data files and the like are stored or by using an identifier. Further, "Cancel" in the screen is a control button selected when instructing to return to the previous screen (here, the genre selection screen), and "Previous",
"Next" is a control button used when switching between screens when many representative screens are displayed, that is, when returning to the previous screen or advancing to the next screen. The control button is common to the reproduction screen, search screen, and search result display screen, which will be described later.

The total time can be calculated by the following formula. Total time = video data capacity / bit rate [sec] (1) Bit rate = (system bitstream multiplex rate) × 400 [bit / sec] (2) where system bitstream multiplex rate is ISO
/ MPEG1 specified in IEC 11172-3
It is a bit rate unit of the system bit stream of.

Further, the first screen of the video data can be used as the representative screen, and as a method of creating it, a representative screen file is created in advance using a format such as GIF, JPEG, or MPEG1.
There is a method of randomly accessing the original video data compressed by to display only the screen. As the latter random access method for displaying the randomly accessed screen as a representative screen, there are a method using a time code and a method using a frame flag.

Each access position can be obtained by the following calculation formula. When using time code: (total capacity x access time / total time) -α bytes (3) When using frame flag: (total capacity x access frame / total frame) -α bytes (4) α is an arbitrary integer, and by using a positive value,
The access position can be a little closer to you. As a result, it is possible to perform reproduction from a little nearer side, monitor the reproduction time code, pause at the corresponding time code, and display the corresponding screen.

When a video title is selected on the video data title selection screen of FIG. 4 (Yes at step S5), it is possible to select whether to reproduce or search the selected video data (step S6). Click the play button to select playback or the search button to select search. Also, as a modification of this, before the genre selection screen is displayed, reproduction is performed in advance.
It is also possible to select a search.

When reproducing the selected video data,
The play button is clicked. Then, in step S7, the video file of the video title selected from the data storage unit 1 is sent to the reproduction unit 2. The image data that has been compressed and accumulated in the reproducing unit 2 is decoded and stored in the display data buffer 7. Then, in step S8, a reproduction screen as shown in FIG. 5 is displayed. On this reproduction screen, the image data of the selected video title is continuously displayed from the beginning to the end.
If you want to stop this playback on the way, click the CANCEL button. In addition to normal reproduction, special reproduction such as slow reproduction, skip reproduction, frame advance can be performed, and the size of the reproduction screen can be changed. PLAY, CUE, SLOW, SS, REW, FF, P in the figure
AUSE and STOP are normal playback, fast-forward playback,
It means low-speed playback, frame advance, rewind, fast forward, pause, stop, and in the case of frame advance, it advances one frame each time it is clicked with a pointing device such as a mouse.

In step S9, it is determined whether or not to continue the reproduction. That is, it is determined whether or not to reproduce the image of another video title. If this determination is positive, the process returns to step S2 and the genre selection screen of FIG. 3 is displayed. On the other hand, when the reproduction is not continued, the process ends.

Next, when searching the contents of the video data selected on the title selection screen of FIG. 4, the search button is clicked. Then, the process proceeds from step S6 to step S10, and the search screen of FIG. 6 is displayed. That is, the search processing unit 6 (see FIG. 1) operates and
The search screen of is displayed. On the search screen, time search,
Scene search, similar image search, etc. are displayed. When any one of these is selected, the selected type of search is executed by the search processing unit 6, and the search result is displayed as shown in FIG. 7 (step S11). After that, when the search screen or the time code in the screen is designated by the pointing device and the reproduction is selected (Yes in step S12), the reproduction from the corresponding screen can be performed (step S8). In this case, with respect to reproduction from the designated place, random access reproduction can be performed using the above formula (3) or formula (4).

Next, each search method displayed on the screen of FIG. 6 will be described in detail. The time search searches the video data at every specified time interval and displays the screen and time code. The time can be specified by selecting the time search on the search screen of FIG. 6 and at the same time starting and ending times (XX: XX to XX: XX) and the search interval (XX
Sec. ) Is specified. It is also possible to specify the time interval in advance, and to match the start and end times with the start and end times of the video, respectively. According to this time search, the video data from the start time to the end time is extracted at the specified search interval and displayed on the screen display unit 4 as a search screen.

In the scene search, the scene change point (cut point) of the video is automatically detected, and the representative screen and time code of each scene are displayed. As the representative screen, the top screen of each scene can be used. The cut points can be detected by, for example, Ushihara et al. "Cut point image detection device and method for moving images", IPSJ 51st Second National Convention 6S-9.
(1995), Japanese Patent Application No. 7-263681, Japanese Patent Application No. 5-
The technology disclosed in No. 216895 or Japanese Patent Application No. 6-46561 can be used.

This technology is, for example, a reduced image creating means for producing a reduced image from input moving image screen data,
The brightness difference between the target screen n (where n is a positive integer) and the reduced images of the screens (n−1) and (n + 1) that are one frame or a plurality of frames away from the target screen temporally before and after is displayed. Comprehensively, the inter-frame luminance difference calculation means for obtaining the inter-frame luminance difference for each frame, and the color difference signal between frames from the histogram of the color difference signal between the reduced images of the screens (n-1), n, (n + 1) And a color difference histogram correlation calculating means for obtaining a histogram correlation value, and the screen (n-
1), a temporal change with respect to the inter-frame luminance difference of (n + 1), and a temporal change of the color difference histogram correlation value of the target screen n with respect to the color difference histogram correlation values of the screens (n-1) and (n + 1). Further, the cut point is detected by including a cut screen determination unit that determines the cut screen of the target screen n.

In the similar image search, after performing the scene search,
A scene for which a similar image search is performed is designated from the representative screen of the scenes displayed as the search result, and the similar image search is selected. That is, when the scene search is performed, the screen shown in FIG. 8 is displayed. Then, a scene on the screen for which a similar image search is desired is selected, and then a similar image search button is clicked. Then, a scene similar to the selected scene is searched, and the representative screen and time code of the scene are displayed as the search result. For example, it is displayed as shown in FIG. 7 or 8. For the similar image retrieval, for example, Nakajima et al.'similar image retrieval apparatus and method ', Preliminary draft of the Institute of Image Electronics Engineers of Japan (1994-06), or Japanese Patent Application No. 7-77098.
The technique described in the issue can be used.

This technique includes, for example, means for setting a reference image, means for selecting a search target image from an input image, and
A means for calculating the similarity for each search target image from the feature amounts of the reference image and each search target image, a means for determining whether the similarity is equal to or more than a predetermined value, and the similarity is not less than a predetermined value. A means for recording each search target image determined to be the same cluster, and a means for updating the feature amount of the reference image using the feature amount of the search target image determined to be the same cluster, The feature amount of the reference image is sequentially updated, and a similar image is searched from the subsequent search target image.

When the screen or time code displayed as the search result is selected, the video can be reproduced from that point. As a method of accessing the specified point, the method of using the time code or the method of using the frame flag as described above can be used.

Further, the following searches can be performed by combining these several kinds of searches.

(1) In FIG. 6, time search and scene search are successively selected. If the time is designated when selecting the time search, the search is performed at the designated time interval, for example, as shown in FIG.
A search screen such as is displayed. Next, when a specific search screen is specified on this screen, a scene search is performed on the video data subsequent to the search screen, and a representative screen of each scene is displayed. In this way, it is possible to perform a search, for example, by performing a time search on a minute-by-minute basis and browsing the contents roughly, then selecting one of the representative screens and performing a scene search from there.

(2) In FIG. 6, when the time search and the similar image search are continuously selected, the search is performed at the designated time interval, and the search screen as shown in FIG. 7, for example, is displayed.
Next, when a specific search screen is specified in this screen,
On the search screen, a scene search is performed on the video data after that, and a representative screen of each scene as shown in FIG. 8 is displayed. Therefore, when the user specifies a desired scene, a scene similar to the scene is searched,
Similar scenes are displayed on the screen.

(3) In FIG. 6, when the scene search and the similar image search are successively selected, the scene search is first performed, and the representative screen of each scene as shown in FIG. 8 is displayed. Next, when the user designates a desired scene among them and presses the similar search button, a scene similar to the desired scene is searched and displayed.

In the case of index search, the search processing unit 6 (see FIG. 1) accesses the index file stored in the data storage unit 1, searches the representative screen based on the index file, and A representative screen and a time code are displayed on the screen display unit 4. The display screen at this time is, for example, the screen of FIG.

There are three possible contents of the index file stored in the data storage unit 1 as shown in FIG. 10, for example. The first index file is an index file in which only time codes are recorded, as shown in FIG. This index file is composed of a time and a frame number corresponding to the time. The example shown is an index file with 30 second intervals. In this case, the search screen every 30 seconds is extracted from the video data of the selected video title, reproduced by the reproduction unit 2 and displayed on the screen display unit 4.

FIG. 10B shows a second index file, which is an index file in which only frame flags are recorded. The number of the frame to be taken out is recorded in advance in this index file. Eg 1
Frame, 100 frame, 200 frame, ..., 50
The frame number is recorded as 00 frame. When the index file is stored in the data storage unit 1, the search screen of the recorded frame is extracted from the video data of the selected video title, reproduced by the reproduction unit 2 and displayed on the screen display unit 4. Will be displayed.

Next, FIG. 10C shows a third index file, which is composed of a representative screen data file and a time code file. The representative screen data is preferably uncompressed video data, but may be compressed. In the case of this index file, since the representative screen data is created in advance and stored in the data storage unit 1, the representative screen data is extracted together with the corresponding time code and displayed on the screen display unit 4 as a search screen. It

Next, a method of reproducing from the image for which the index search is performed will be described. In the case of an index file containing only time code, the playback from the search image predicts the corresponding position of the video data using the selected time code, total time, and capacity, as described above, and starts playback from that position. To do. In the case of a frame flag index file, the corresponding position of the video data is predicted using the selected frame flag, total frame, and capacity, and reproduction is performed from that position. In the case of the image file and the time code index file, the video data corresponding to the selected time code is randomly accessed for reproduction. As for the reproduction, the special reproduction and the reproduction screen size can be changed as in the first embodiment.

FIG. 11 shows the structure of files stored in the data storage unit 1. Files are stored in a directory structure. In the case of (a) in the figure, a video file is used to display the representative screen, and an index file is used to display the search screen. In this case, the representative screen uses an image at a fixed position such as the top screen of the video. In the case of FIG. 3B, the title file is used to display the representative screen, and the index file is used to display the search image. The title file may include the title screen itself as a file, the time code of the representative screen, or the frame flag of the representative screen. As described above, the index file may have the index screen itself, the index time code, or the index frame flag.

The above embodiment is an example in which the present invention is applied to a system in which image data stored in a hard disk is directly accessed from a personal computer, but the present invention is not limited to this and is shown in FIG. It can also be used for a system in which a server and a client are connected via a network. The system configuration will be described with reference to FIG.

On the c side, using the data transmitted from the server 11,
Playback of video data and display of search results are performed.
As a transmission control means, for example, in a LAN, NFS (Ne
By handling the server as one virtual device of the client by using the work file system, random access can be performed by the same method as the read / write of the data of the hard disk incorporated in the client. The server may be a WWW server on the Internet, and the client side may be provided with a WWW viewer for playing back and displaying the search results.

FIG. 13 is a flow chart showing the operation when the above system configuration is used. Step S1 ~
Since S6 is the same as or equivalent to that in FIG.
The step S21 and subsequent steps will be described. In this system configuration, the data storage unit 1 (see FIG. 1) is the server 11
Of the hard disk 11a. Therefore, when reproduction is selected in step S6, the process proceeds to step S21,
The video data of the selected video title is the server 11
From the client side to the client 12 side. Next, in step S22, the playback screen of FIG. 5 is displayed on the client 12 side, and the playback image of the video data is displayed on the playback screen. In step S23, it is determined whether or not to continue the reproduction. If the determination is affirmative, the process returns to step S2 and the genre selection screen is displayed again.

Next, when the search is selected in step S6, the process proceeds to step S24 and the search screen of FIG. 6 is displayed. Then, similarly to the above, selection of time search, scene search, similar image search, and index image search is performed on this screen. In step S25, the server 11 starts the search selected in step S24, and transmits the search result from the server 11 side to the client 12 side. In step S26, the client 12 side displays the received search result. In step S27, it is determined whether or not to reproduce the search screen. If the determination is affirmative, the process proceeds to step S28, and the server 11 reproduces the image. Then, the reproduced video data is transmitted to the client 12 side. Then, the process proceeds to step S22, and the reproduced image is displayed on the monitor on the client 12 side.

As described above, according to this embodiment, since the compressed image data is stored in the data storage unit 1 or the hard disk 11a of the server, the data amount is small, and the data storage unit 1 Alternatively, since desired search among time search, scene search, similar image search or index image search can be performed on the image data stored in the hard disk 11a of the server, the desired search can be performed in a short time from the video data. The scene of can be taken out. In addition, since the reproduction can be started from the extracted scene as needed, only the desired scene can be reproduced easily and in a short time.

In the above embodiment, as shown in FIG. 6, four types of search that can be selected are time search, scene search, similar image search and index image search.
Although types are provided, the present invention may be one type of them, or may be two types or three types of any combination.

[0047]

As is apparent from the above description, according to the present invention, the search device automatically searches and retrieves the search result without reproducing the video data from the beginning to the end unlike the conventional case. Since it is displayed, it can be searched in a short time without any trouble. Further, since the reproduction can be started based on the searched screen, the user can find a place he / she wants to see in a short time and reproduce from the found place, which is an effect that the operability is greatly improved. There is. Further, the above-described search and reproduction can be realized also in a system including a server having means for accumulating video data, a network connecting the server and the client, and a client connected to the network. It has the effect that it is possible and has great practical value. Further, according to the present invention, there is an effect that it is possible to perform a search by designating a time interval, a scene search, a search for similar scenes, a search combining these, or an index search.
