Detailed Description of the Invention

Shown in FIG. 1 is a video camera 4, an image processing board 6, a CD-ROM or laser disk driver 8, and a VTR 12 as the image processing support apparatus 10 and its peripheral apparatus of the present invention. And a computer 2 are connected.

The video camera 4 is an input medium for inputting image information of a person (viewer) to be converted and its output is connected to the image processing board 6 and is controlled by the computer 2.

The image processing board 6 changes the image information input through the video camera in three dimensions. The image processing board 6 records and indexes the data necessary for changing the character of the image information displayed on the screen, and then inputs the person based on this. The image information of the image is enlarged, reduced or changed in direction to be modulated. The data required for the change is recorded in a separate memory. The image processing board 6 is connected to receive a signal of the video camera 4 and is controlled by a computer.

The CD-ROM or laser disk driver 8 is used as an auxiliary memory and can record and read video and audio data.

The VTR 12 is a recording medium for recording the synthesized signal, and the computer 2 is used for controlling the image conversion speed and peripheral devices, and has an operating system (OS) for image conversion control. That is, a general personal computer is used as a control computer and a CD-ROM or a laser disk is used as a high capacity memory device.

Using the video camera 4 or the like, the 3D wire frame face information of the person to be converted is stored on the hard disk, and on each screen, a laser disk or a CD-ROM containing a re-edited movie based on this information. Save the substitution data. The replacement data is calculated by processing (enlarging, reducing, reorienting, etc.) three-dimensional frame face information recorded by the video camera 4 or the like based on the information of the screen to be converted and the index information.

The substitution data calculated as described above is synthesized using the image processing support apparatus 10 of the present invention. That is, the image processing support apparatus displays the portion of the face (mostly processed in the background color) that is to be included in each screen while the movie is being displayed by the CD-ROM driver 8 including the re-edited movie. Replace using (10). This will not change the part that is not a face, the effect of changing only the intended part (face of the character). The synthesized movie is separated from the image processing support apparatus 10 and recorded using the VTR 12 to obtain a movie in which the face of the character is changed.

Shown in FIG. 2 is a schematic block diagram of an image processing support apparatus 10 for synthesizing image information as described above, and a high capacity memory element 26 for storing data, image index and conversion data for each screen to be replaced. Driver control circuit 28 for driving CD-ROM or laser disk driver 8, D / A converter 34 for converting digitized information into analog signal, synchronizing signal for matching horizontal scan and vertical scan A circuit 36, a composite video separation circuit 38 for separating the composite video signal output from the D / A converter and the synchronization signal generating circuit into an image signal and an audio signal, and an I / O terminal of the computer 2 A communication bus controller 24, a video memory RAM 32, a bus controller 30 for controlling signals of a driver control circuit, and a microprocessor 22 for system control.

Information input to the high-capacity memory element 26 is inputted through a medium such as the video camera of FIG. Location data of each screen of the recorded movie. The transformed information here is a three-dimensional solid modeled information in which white joy is expressed so as to be inserted into a corresponding region of the movie screen.

The driver control circuit 28 operates by key input of the computer 2 and drives the driver 8 to play a CD-ROM or a laser disk containing an edited movie.

This reproduction signal is input to the video memory RAM 32 via the data bus of the bus controller 30 and stored in the graphics mode. The screen in graphic mode displays the intensity and color of each point as a bitmap, so to change the contents of any point on the screen, the location (address) value of the storage location is changed.

The microprocessor 22 reads the image index information and the conversion information memory stored in the memory element 26 in response to a control signal input through the keyboard of the computer 2. Thereafter, the image conversion image is recorded in the corresponding position of the video RAM 32 to synthesize a movie.

The image signal synthesized as described above is 8-bit memory data. This memory data is converted into an analog signal through the D / A converter 34. The converted signal is again divided into an audio signal and a video signal through a composite video signal separation circuit 38, and the separated signal is recorded on a video tape using the VTR 12.

The above recording method is a method of synthesizing an already created three-dimensional solid model with a movie, but another method is to record the three-dimensional solid modeled data based on index information directly on a CD-ROM or a laser disk containing the edited movie. It is also possible in the image processing support apparatus of the present invention.

In this case, however, reprocessing of the resaved data is necessary in order to return the original character or the edited film whose face is erased. Therefore, in the detailed description of the nickname, the former method of synthesizing the three-dimensional solid model and the movie with the face of the main character or the character edited using the image processing support apparatus will be described.

Each screen data is data in which a specific region of the main character or the character is erased from the edited movie. The data of the specific region is the position data of the region displayed on the screen of one frame of the movie. In the present invention, the screen of one frame has 70 * 70 pixels.

On the basis of the positional data on the frame as the conversion information and the image color data, the image conversion image memory is data converted and produced appropriately for each frame. This converted image memory is mainly a face shape that expresses emotions such as emotions of a specific person in a movie to be edited. The converted image memory is converted using the image processing board 6 based on the image index data and the position data inputted or inputted using a video camera or an image scanner or the like. The memories are stored in the high capacity memory element 26.

When the data is ready, the screen compositing operation starts. Under the control of the computer 2, the CD-ROM or the laser disc driver 8 is driven to reproduce the movie. This reproduction signal is input to the image conversion support apparatus 10 using the input / output terminal of the computer 2. At the same time, the replacement data recorded in the memory element 26 of the image conversion support apparatus 10 is output by the control signal of the computer.

The driver signal and the signal reproduced by the memory device are input to the video RAM 32 under the control of the bus controller 30 and synthesized one frame at a time. The synthesized signal is again modulated into an analog signal through the D / A converter 34, and the vertical synchronization and the horizontal synchronization are adjusted in the synchronization signal generation circuit 36.

The modulated analog signal is separated into audio and image signals by the composite video signal separation circuit 38 and then recorded by an image recording medium such as a VTR.

The above description is shown in the system control flowchart of the present description shown in FIG. The three-dimensional wire frame information is mainly information on the face state of the main character or the character, and is conversion information and index data for each corresponding screen. In other words, the expressions of facial expressions, white joy, and the like on one screen, and data of positions replaced throughout the movie for various situations such as planes and three-dimensional models. This converted data can be stored in the hard disk of the control computer.

When compositing begins, the computer reads the conversion information and index data of each screen and records various positions and states such as the size of the screen to be replaced, the viewing angle, the white joy, the shape of the mouth, and the eyes.

Based on the recorded data, the computer creates a screen-specific solid model to be inserted into the corresponding screen portion and stores it in the memory element 26 of the image conversion processing circuit. In this way, when the production of the per-screen solid model to be replaced is completed, the solid model data is recorded on the laser disk or CD-ROM. Here, the image processing support apparatus is used to adjust the vertical and horizontal synchronous signals and control them to be converted into composite video signals. The converted signal is separated and stored in a recording medium such as a video to complete the editing of the movie. The corresponding information of the original CD-ROM or laserdisc is removed and reproduced in an empty state for the following operation.

As another method, the index information for each screen is read and the bus controller 30 is controlled to synthesize film and solid model data using the index information, and to perform D / A conversion on the synthesized signal. That is, the CD-ROM or the laser disk driver 8 is driven to reproduce the movie, and the bus controller 30 synthesizes the reproduction signal and the solid model data stored in the memory element 26 in the video RAM 32. The synthesized signal is divided into sound and video signals in the composite video signal separation circuit 38 after horizontal and vertical synchronization is controlled in the synchronization signal generating circuit 36 and then recorded in the VTR. In this way, the process is simplified because there is no face part of the main character in the original CD-ROM or laserdisc. However, a separate image conversion support device is needed.

As described above, it is possible to easily produce a movie using any person as a main character by using the method and the image processing support apparatus of the present invention.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention and therefore should be limited within the scope of the appended claims.
