Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention is used for creating video information. The present invention relates to a technique for combining and displaying a plurality of individually shot images. INDUSTRIAL APPLICABILITY The present invention is used for producing a television broadcast program, practicing acting, producing a TV drama, auditioning an actor, karaoke, and the like.

[0002]

2. Description of the Related Art When a drama by a plurality of performers is shot by a television camera in a studio,
A stage set consisting of props and props is prepared, and each performer performs his or her own performance based on the script in front of the stage set. Each performer performs the performance by detecting the timing at which he or she performs, based on the movements or dialogues of the other performers, and one drama is established by cooperation between the performers.

[0003] A television drama is produced by editing a plurality of scenes, and in the case where an actor's failure or the like has occurred, only the scene can be retaken. In addition, it is possible to shoot each scene while ignoring the context of the story, edit the scene after the shooting is completed, and adjust the context of the story.

Conventionally, various synthesizing apparatuses for synthesizing a plurality of video signals are known. A still image or a slowly moving image can be prepared as a background image, and can be combined with an acting image to create one scene. The present applicant has disclosed a device for rationally distinguishing a background image from a performance image in Japanese Patent Application No. 8-278326 (not disclosed at the time of filing the present application).

[0005]

For example, a TV drama is formed by the cooperation of a large number of performers, and a large number of performers adjust their schedules, meet together, practice, and shoot. . At present, at least those who appear in the scene cannot shoot unless all of them gather at the shooting location.

[0006] Therefore, the scheduling of the performers is restricted, and there is less room for practice time or recording time, and the director who supervises the drama must complete the drama by compromising in the less time. It is not always possible to complete the work according to the director's wishes. In addition, each performer has a different ability, and although it originally requires different practice time, uniform or limited practice for adjusting the schedule with other performers Only time is given.

[0007] Regarding the stage set as the background, the period during which this set is installed is the minimum period necessary from the viewpoint of studio use efficiency, and even during the practice period, the background set is the same as the actual set. Despite the benefits of practicing, it is impossible for a performer to repeat enough practice in front of the same set as the production.

[0008] In the process of shooting a drama, if there is an error in one actor in a scene with a large number of performers, all the other performers who have no mistake in re-shooting the scene will have to perform the scene. If it is necessary to perform the action again from the beginning, and if other actors make mistakes in this re-shooting scene, the shooting will not end even if it passes forever.

On the other hand, in the field of music performance, accompaniment and solo,
2. Description of the Related Art Accompaniment and solo singing are separately recorded, and a technique of recording one tune by synthesizing them separately later is widely used. Utilizing this technology, ensemble or chorus by a single player has become possible.

The present invention has been made in such a background and provides an apparatus capable of combining television images of a plurality of individually photographed subjects as if they were photographed simultaneously. With the goal. The present invention
It is an object of the present invention to provide a device in which each performer of a drama can participate in the drama according to an original schedule without meeting with other performers. An object of the present invention is to provide a device that can create a new drama by synthesizing a plurality of individually shot and patterned performances. SUMMARY OF THE INVENTION An object of the present invention is to provide a studio device that can freely change a background image of a drama. SUMMARY OF THE INVENTION It is an object of the present invention to provide a device capable of freely replacing a picture of a singing person with a band accompaniment.

[0011]

SUMMARY OF THE INVENTION The present invention relates to a video signal synthesizing apparatus.
Is an input terminal of a video signal of 1 or more), and digital recording means capable of recording video signals of N channels (N is an integer of 2 or more) to be combined in parallel by assigning a corresponding number to each frame. Reproducing means for reproducing video signals of two or more channels recorded in the recording means on one monitor device as a composite video; and recording the video signal of the input terminal in the digital recording means in synchronization with the reproducing means. And an operating means for editing and reproducing the corresponding numbers in chronological order according to the operation.

The video signal of at least one channel of the video signal recorded in the recording means is a background video signal,
It is preferable that at least one channel of the video signal arriving at the input terminal is a performance video.

Thus, for example, a large number of performers can be individually photographed, the size and position of each video image can be appropriately set, and these can be combined to further correct the context to create one drama. Can be completed.

[0014] The television camera may be provided for each of a plurality of subjects, and may have means for taking pictures in synchronization with each other.

That is, for example, when a plurality of performers meet and perform a drama, these performers are individually photographed by a plurality of television cameras, and the respective images are individually recorded in the memory. May be recorded.

At this time, a special blue screen called a blue back is arranged in the background, and only the video of each performer is extracted from the video signal and recorded.
The size and position of the video of each performer can be freely set and displayed. Further, when the images of a plurality of performers overlap, the image of the subject in charge of the television camera may be extracted and processed.

Preferably, the display means includes means for displaying a common background for each of the video signals simultaneously displayed on the screen.

That is, for example, images of individual performers can be synthesized, and a background image separately shot can be synthesized with the background. Therefore, the stage set is individually photographed within a short time and synthesized with the performer's video, so that the performer can freely confirm the relationship between the background and his or her performance on the screen.

Preferably, the reproducing means includes means for reproducing the video signal at the input terminal as a composite video in conjunction with the video signal recorded in the recording means. This allows
It is possible to combine a plurality of video signals that have already been recorded with a real-time video signal that is currently being captured. For example, by using for the audition of the actor, by combining the acting of the actor receiving the audition into the acting of a plurality of performers photographed in advance,
The judge can check the atmosphere of the scene for each of the actors undergoing the audition.

(Summary of the Embodiment) According to the first embodiment of the present invention, for example, the performances of drama performers are individually photographed and their video signals are synthesized, so that a plurality of performers can simultaneously perform the performances. You can create an image as if you were going. Therefore, the degree of freedom of the performer's schedule can be increased. In addition, when there is a failure in the performance, only the performer corresponding to the failure performs the performance again, so that a drama without failure can be completed. Alternatively, regarding a difference in practice time caused by a difference in personal abilities of the performers, a performer who wishes to practice for a longer period than other performers displays an image of the other performer on the display unit 6. By synthesizing the video of one's practice while displaying it, it is possible to experience the feeling that the performers are all practicing alone, even though they are alone. Furthermore, since the background image can be arbitrarily combined, only the background can be changed without changing the image of the performer's performance.

According to the present invention the second embodiment [0046] When the cast all were rehearsing aligned, each performer by each performer is photographed by each individual television camera 1 ₁ to 1 _n Video can be created.

Alternatively, a new drama can be completed without recruiting performers by patternizing a plurality of performances for all scenes and shooting them in advance, and the director appropriately combines the images. It can also be done.

As another application example of the first and second embodiments of the present invention, for example, images of a band performing a performance and a singer are individually shot, and the image of the singer is replaced with another singer. You can audition a new singer without actually preparing a band. This application example can also be applied to, for example, combining a singing person's image with a professional band's image in a karaoke box and enjoying it.

[0049]

As described above, according to the present invention,
It is possible to combine images of a plurality of subjects that are individually shot as if they were shot simultaneously. This allows
For example, each performer of the drama can participate in the drama on its own schedule without meeting with other performers. Alternatively, a new drama can be created by combining a plurality of individually shot and patterned acts. In addition, the background image of the drama can be freely changed. In addition, the images of the singing person can be freely replaced by the accompaniment of the band.
