[Prior art]

 In recent years, so-called karaoke boxes, in which a karaoke device is installed in each room, have become popular. In a general karaoke box, video and audio signals were not transmitted between the rooms, and only people in the same room could make a duet.

Therefore, a camera and a monitor are arranged in each room so that a person in another room can make a duet, and the video signals picked up by the cameras in both rooms are combined to synthesize each room. The karaoke box system that is displayed on the monitor has come into use. In this case, the audio signals from the microphones in each room are mixed and the speakers in both rooms are sounded.

[Problems to be solved by the device]

 In the above-mentioned conventional karaoke box system, the screen of the monitor is divided into four, and the images taken by the cameras in both rooms are displayed on the upper right and upper left split screens, respectively. Also, images and the like by the karaoke device are displayed on the lower right and lower left screens. The screen divided into four is a horizontally long screen having the same shape as a normal TV screen.

When people in different rooms make a duet using this system, the composite image is projected as a shape in which two horizontally long screens are arranged side by side, and becomes extremely horizontally long as a whole. And only a part of the composite image is used. The background of the room is shown in other areas, and it does not contribute much to the duet composite image.

[0006] Furthermore, in the conventional system described above, in order to synchronize the video signals picked up by different cameras which are not synchronized with each other in the horizontal and vertical directions, a four-partitioned partition has a fairly wide white band, and one of The split-screen image was projected a few seconds later than the other. In such a state, there is a drawback that the atmosphere in which two people are duet cannot be created.

The present invention has been made to solve the above problems, and its purpose is to divide a monitor screen into two in the horizontal direction by vertical dividing lines, and to divide people into different screens into different rooms. An object of the present invention is to provide a duet image compositing display device capable of composing a natural duet landscape by projecting it.

In addition to the above-mentioned conditions, another object of the present invention is to narrow the width of the divided parts and to display the images of both divided screens with no time delay so that the two people actually see the singing person. It is to provide a duet image compositing display device that gives the feeling of having a duet side by side.

[0009]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an overall configuration diagram in which a duet image compositing display device according to an embodiment of the present invention is applied to a karaoke box. There are ten karaoke boxes to which this embodiment is applied, and a karaoke device 1 using a video disc or a compact disc is arranged in each room.

The karaoke devices 1 are independent of each other, and the user can enjoy karaoke without using the duet image composition display device. In addition to the karaoke apparatus 1, there is a video signal processing system 10 and an audio signal processing system 8 of the present invention, which are controlled by a personal computer 7 arranged in the control room.

The personal computer 7 operates according to a signal from the operation keyboard and a signal from the touch panel of the display 6 with a touch panel arranged in each room, and controls the video signal processing system 10 and the audio signal processing system 8. At the same time, data and the like are displayed on the display 6 with a touch panel.

The audio signal processing system 8 mixes signals from arbitrary microphones 5 arranged in each room or independently drives the speaker 4 in the room specified by the personal computer 7, which is well known. Since it can be configured by means, its details will not be described.

The video signal processing system 10 synthesizes a video signal from an arbitrary camera 3 arranged in each room, or causes the monitor 2 in the room designated by the personal computer 7 to independently display the video signal. .

Next, the video signal processing system 10 will be described in detail with reference to FIGS. FIG. 2 shows the overall configuration of the video processing system. The camera 3 outputs the RGB signals of the three primary colors synchronized with the horizontal and vertical synchronizing signals input from the outside, and the composite video signal. The ten composite video signals output in this manner are input to the video signal switcher 13. Further, the 10 RGB signals are input to the camera selection circuit 11.
