Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image synthesizing apparatus for exchanging information between a plurality of terminals and synthesizing images with rich expressiveness.

[0002]

2. Description of the Related Art Conventionally, for example, a person image is extracted from an image of a landscape in one's own space, and the image and the person image sent from the other party are displayed commonly with the other party stored in advance. By superimposing and displaying an image of a virtual space, the presence of the other person in front of him is satisfied, and there is a thing aiming at a realistic image communication (Japanese Patent Publication No. 4-24914).

Personal Computer Communication System: Fujitsu Ha
bitat ", FUJITSUSci. Tech.J., 26, 3, pp.197-206 (Oct
ober 1990).), Nakamura: "Support for distributed collaborative work by virtual reality for networks", IPSJ Audiovisual Complex Information Processing Research Group (1993)).

[0003] In the prior art, for providing an image communication service to which image synthesis is applied on the premise of a communication environment in which the performances and communication capacities of respective terminals are almost equal, such as a conference system for use in an office. The system has been considered.
Therefore, no consideration is given to an image communication system that applies image combining under the communication environment such as CATV in which the performances of the respective terminals are greatly different and the communication capacities of the terminals are greatly different.

In the prior art, since a system having a narrow communication band such as Ethernet or N-ISDN is targeted,
Image synthesis with rich expressiveness using moving image information has not been realized. Also, the communication capacity from the center side terminal to the home side terminal is large, and the communication capacity in the opposite direction is small,
In the conventional two-way CATV, the existing package software such as movies and games has been used in many cases to be transmitted from the center side terminal to the home side terminal according to the user's request (the image utilizing the communication characteristics of the two-way CATV is used. Communication method of synthesis is not considered). Note that the communication mode considered in the present invention is not limited to the wired bidirectional CATV, but the transmission of video and audio from the center side terminal (broadcasting station) to the home side terminal is performed by radio waves (for example, VHF band, UHF band). ), The control data may be exchanged between the center side terminal and the home side terminal by an analog telephone line or N-ISDN.

Further, according to the conventional technique, a foreground image component (for example, a person character) previously represented by image information for creating a foreground on a home-side terminal and a background image (similarly a landscape represented by image information). Such a "mountain or the sun") is provided in a CD-ROM or the like (the system designer determines in advance the distinction between the foreground and the background). If a user issues a command request to operate the foreground information or background information from a home terminal, a low-speed communication line such as an analog telephone line will be used to send another command via the center terminal. The foreground information and background information displayed on the user's home terminal are changed in response to a command request (only command exchange). Therefore, it is not possible to realize a moving and realistic image communication system utilizing the communication characteristics of CATV, which effectively utilizes moving image information as realized by the present invention.

Further, in the conventional technique, the image synthesizing method requires the user to explicitly operate the input device such as a keyboard or a mouse, so that the user can use the terminal device depending on the usage status of the terminal. Image composition was not enough.

[0007]

According to the conventional method, in order to realize an image communication service utilizing image synthesis, an image part (for example, a human character) represented in advance by the image information for creating a foreground on a home-side terminal is realized. ) And a background image (also represented by image information).
When a user issues a command request to operate the foreground information or background information from a home-side terminal, a low-speed communication line such as an analog telephone line is used, and another use is made via the center-side terminal. The foreground information and the background information displayed on the home terminal of the user are changed in response to a command request.
Therefore, the communication capacity from the center side terminal to the home side terminal is large and the communication capacity in the opposite direction is small.
There is a problem that the image communication service utilizing the image synthesis with rich expressiveness that effectively utilizes the communication characteristics of is not realized.

It is an object of the present invention to realize an image synthesizing apparatus capable of exchanging information between a plurality of terminals and synthesizing images with rich expressiveness.

FIGS. 3A and 3B are views for explaining a method of performing image synthesis in a concentrated manner and a method of performing image synthesis in a distributed manner. In the example of the figure, the image parts of "Sun" and "Mountain" are background images, and "Person" and "
The image component of “bird” is a foreground image. (A) is a method of intensively synthesizing images, and each image component is synthesized by the terminal support device. The synthesized image information is video information as the terminal device. (B) is a method of synthesizing images in a distributed manner, and the background image component is transmitted as video information from the terminal support device to the terminal device. At, it is combined with the foreground image component fetched from the terminal device or combined with the foreground image component transmitted from another terminal device or the terminal support device.

FIG. 4 is a diagram for explaining a method of transmitting the foreground component and the background component. As shown in the figure, in the centralized image synthesizing method of (a), the foreground component is a terminal device (terminal).
From the terminal support device (center terminal) or managed by the terminal support device. As described above, the foreground component and the background component are created as video information by the terminal support device and transmitted to each terminal device. In the distributed image synthesizing method of (b), information in which the background image is transmitted as video information from the terminal support device to the terminal device, the foreground parts owned by the terminal device itself, and the information transmitted from other terminal devices are transmitted. The image is synthesized with the received foreground component or the foreground component transmitted from the terminal support device to each terminal device.
In the distributed image composition of (c), the background image information is distributed from the terminal support device to each terminal device as video information. The information on the foreground image component is transmitted in a loop between the terminal devices without passing through the terminal support device. The major difference between the distributed type and the centralized type is, as described above, the difference in the load on the terminal support device for image composition.

Further, the difference between (b) and (c) is that, in the case of (c), the foreground parts are not transmitted to the terminal support device, so the load on the terminal support device is reduced. On the other hand, in the case of (c), it takes time and effort for the terminal device to newly add or delete the image during the image combining process. Therefore, in order to maintain the consistency of the foreground parts among the terminals and to join or delete the terminal device halfway, as appropriate, for example, at fixed time intervals, when the terminal device is added, or when the terminal device is deleted, The terminal support device compares and adjusts the states of the foreground parts managed by the device, thereby reducing labor. However, instead of the terminal support device performing the adjustment and comparison of the states of the foreground parts managed by each terminal device, it can also be realized by a method of performing the inter-terminal operation between the terminal devices (determining the terminal device that plays the role of the terminal support device. You can leave it). (C)
Especially for one-way CATV and existing LAN and ISD
This is effective when different types of networks such as N are used together.

FIG. 5 is a diagram for explaining the configuration of the screen compositing unit. The image composition section described with reference to FIGS.
An object-specific information management unit 51 that manages object-specific information for creating an image, an object-object position information management unit 52 that manages position information between objects, and information on mutual interference between objects. The object mutual interference information management unit 53 and the image synthesis control unit 54 that controls these units are configured. Specific management information will be described below.

6 to 10 are views for explaining the information managed by the object specific information management unit which manages the unique information of the object for which an image is to be created. In the example of FIG. 6, as the information to be managed, the information of the foreground part is managed (the same as the information stored and managed by the foreground screen creation information management unit), the character name (the name of the foreground part), the character ID, and the character. Information on the size, center coordinates (coordinates of the character's center of gravity), and how the character behaves (production rules) is managed. FIG. 7 is a visual representation of the information managed in FIG. In the example of FIG. 8, the information of the background image is managed (the same as the information stored and managed by the background screen creation information management unit), the background image name and the background image I.
D, each piece of information of the effect code indicating the content of the effect as the background image is managed. In the example of FIG. 8, the image information expressing the effect effect at the time of collision or encounter between characters is managed as the information of the background image, but in the example shown in FIG. It is managed as part information. Therefore, in the example shown in FIG. 10, the robot and the stone are managed as the information of the foreground parts. As shown in the figure, whether the effect at the time of collision is the foreground information or the background information may be appropriately managed at the time of designing the application according to the purpose of the system designer. Note that, together with the information registered by the user as the foreground image component, similarly, the user may register the sound effect as information for effect in order to enhance the effect of effect.

11 to 14 are views for explaining the inter-object position information managing unit for managing the position information between the objects. Specific management information managed by the inter-object position information management unit will be described. In the example of the figure, the character ID of the foreground part currently used and the coordinate position where the character currently exists are managed. Although not shown in the figure, management of the coordinate position of the background image can be realized in the same manner. It should be noted that the foreground image and the background image may be constructed as three-dimensional information, and in that case, depth information may be taken into consideration (even if two-dimensional information is used, the overlapping state between characters is taken into consideration. As with dimension CG, it is sufficient to consider depth. Even if two characters overlap, it is possible to create a situation where they do not collide.)

FIG. 12 shows a concrete example in which the collision determination between the background image and the foreground image is performed. The illustrated example is an example of determining whether a bird collides with a tree. Birds are managed as foreground parts, trees are managed as background parts, and part-specific information such as size and center coordinates of parts is managed by the object-specific information management unit described above. In addition, the current state of each image component is managed by the inter-object position information management unit described with reference to FIG. In the example of the figure, the approach distance between the objects is measured based on the center coordinates of the respective parts. When the approach distance becomes smaller than a certain value, it is determined as a collision, and based on the rule of the effect effect on the screen at the time of the collision of the object-to-object mutual interference information management unit which manages the information of the mutual interference between the objects described in FIG. , Realize a series of on-screen effect.

The foreground component and the background component may be moving images as shown in the figure. When the entire background image is used as the video information, the video captured from the camera (the camera may be freely controllable by the user as shown in FIG. 13) or a part of the video information is clipped. An image (cut out) (for example, the image shown in FIG. 14) or a VT
If the images recorded in R etc. are related to a specific area (eg, "mountain", "sun", "tree") of each video scene, "tree" will be taken. Area) that has a background image to be subjected to a collision determination is recorded and managed in association with each video scene, so that collision determination processing with a foreground component is performed even if the background is a video. Can be realized.

FIG. 15 is a diagram for explaining an inter-object mutual interference information management unit for managing information on mutual interference between objects. In the example of the figure, (a) the effect of the foreground image or the background image on the screen is managed. (A)
Based on the above information, a series of time-dependent production rules for the foreground image or the background image on the screen are defined in consideration of the time axis. For example, in the case of pat # 1, when it encounters (when the approach distance between objects is below a certain level), it is an “explosion”, and when it collides (when it becomes smaller than the limit value of the approach distance determined by the application in advance). ) Is directed to "fall down".

FIG. 16, FIG. 17, and FIG. 18 are diagrams for explaining the concrete exchange of information including the passage of time between terminals. The methods of FIGS. 16 to 18 correspond to the methods of (a) to (c) shown in FIG. 4 above.

In the centralized management type system for performing intensive image composition shown in FIG. 16, for example, a foreground image transmitted from the terminal device A (terminal A) (for example, its own person image, face image, portrait, 3 3D CG, video, etc.) received by the terminal support device, background image (still image, 3D CG, video, etc.)
And the composition result is transmitted to each terminal as video information. In particular, the user's willingness to use is increased by using his / her face image as information for image synthesis. In addition, a command for operating the foreground component (for example, a command such as "move (right)" for operating the foreground component by making an agreement in advance between the terminal device and the terminal assistance device) is transmitted from the terminal B to the terminal assistance device. The foreground component is operated according to the command for operating the foreground component, and the foreground component image and the background image that have been manipulated are combined by the terminal support device and transmitted to each terminal device. The background image and the foreground image, the collision determination between the foreground images, and the like are intensively performed by each terminal support device by the above-described method.

In the distributed image synthesizing method shown in FIG. 17, for example, the foreground image is transmitted from the terminal A to the terminal support device and is transmitted to each terminal. Further, the foreground component is transmitted from the terminal support device to each terminal device. Each terminal device performs image composition together with the background video information transmitted from the terminal support device. Further, when an operation request for operating the foreground component is generated from the terminal B, it is transmitted to each terminal device via the terminal support device. The background image and the foreground image, the collision determination between the foreground images, and the like are performed by the terminal devices in a distributed manner by the above-described method.

In the distributed image synthesizing method of FIG. 18, for example, when the foreground component is transmitted from the terminal B, the route (each terminal sends information to which terminal and which terminal sends information by the system) in advance. It stores and manages whether information comes in. Token ring-like communication form like FDDI)
The foreground parts are sequentially transmitted without going through the terminal support device. Further, regarding the operation on the foreground parts, the operation commands are sequentially transmitted without going through the terminal support device. The background image and the foreground image, the collision determination between the foreground images, and the like are performed by the terminal devices in a distributed manner by the above-described method.

19 and 20 are diagrams for explaining specific examples of information exchanged between the terminal support device and the terminal device.
As shown in FIG. 19, the information exchanged between the terminals includes, for example, a destination, a source, a character ID (foreground component or background component), a command ID (component operation I).
D), consisting of command arguments. As specific commands, as shown in FIG. 20, information such as command names, command IDs, command arguments, and execution contents of commands is managed.

FIG. 21 is a diagram for explaining the video feature amount extraction unit. In the configuration of FIG.
The terminal support control unit 20 of the terminal support apparatus 102 intensively performs this. Further, in the configuration of FIG. 2, the terminal controller 26 of the terminal device 201 disperses and extracts the feature amount of the video.
An image feature amount extraction unit that extracts an image feature amount, a hue feature amount extraction unit 1901 that checks the hue information of the image, a luminance feature amount extraction unit 1902 that checks the luminance information of the image, and a saturation information of the image. A saturation feature amount extraction unit 1903 and a video feature amount extraction control unit 1904 that controls and manages each unit that extracts the feature amount of the image. Changes in the features of the image,
By quantifying the relationship with the effect described in FIG. 15, the user can use the input device such as the keyboard or the mouse to operate the terminal of the user without explicitly operating the user. It is possible to perform appropriate image composition. For example, in online karaoke using image synthesis, education, etc., it is possible to perform the foreground component and the background component in accordance with the user's movement (for example, the screen is distorted, the screen flashes, etc.).

FIG. 22 is a diagram for explaining the voice feature quantity extraction unit. The extraction of the voice feature amount is performed in the configuration of FIG.
The terminal support control unit 20 of the terminal support apparatus 102 intensively performs this. Further, in the configuration of FIG. 2, the terminal control unit 26 of the terminal device 201 dispersively extracts the voice feature amount.
A voice feature amount extraction unit that extracts a voice feature amount includes a sound volume detection unit 2001 that checks a sound volume, a voice pitch extraction unit 2002 that checks a sound pitch, and a utterance command that checks a user's utterance command. The extraction unit 2003 and an audio feature amount extraction control unit 2004 that controls and manages each of these units. When detecting the pitch of a sound, for example, a voice signal picked up by a microphone is passed through a low-pass filter to remove the overtone portion, and then the A / D is set at a sampling frequency of 20 kHz.
The basic period is calculated as 12-bit digital data after conversion. The basic period may be obtained by measuring the time between peaks having an amplitude equal to or greater than a preset threshold value. As described with reference to FIG. 21, the change in the voice feature amount and the change in FIG.
By quantifying the relationship with the effect described in, the user can use the input device such as the keyboard and mouse without the user's explicit operation, depending on the usage status of the user's terminal. It becomes possible to perform image composition. In addition to the voice feature amount shown above, it is also possible to use the voice feature amount such as the rhythm and tone of the sound. Similarly to the above, in online karaoke using image synthesis, education, etc., it is possible to produce the foreground parts and the background parts according to the user's movement.
