JP2001045373A - Karaoke video compositing device for allowing singer to perform on screen - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a system for allowing a singer singing by karaoke to perform on a screen in a real time by image picking-up, compositing, and displaying the singer between 'background video display' and 'lyrics caption display' in the screen in a karaoke device accompanied by video display. SOLUTION: In a karaoke device for independently processing video for displaying a lyrics caption 4 from a background video 3 among karaoke devices accompanied by video display, a video compositing device connected with an image pickup system (CCD camera or like) is inserted between the reproducing device of the background video 3 and a device for compositing the lyrics caption display so that a singer singing by karaoke can be image picked-up, composited, and displayed at the front side of the background video on the video screen and at the rear side of the lyrics caption (a pat other than the lyrics caption display on the screen), and the singer can perform on the screen.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a video compositing process in a karaoke apparatus with video display.

[0002]

2. Description of the Related Art At present, a video display system such as a communication karaoke which is the mainstream of a karaoke apparatus, as shown in FIGS. Then, a lyrics subtitle display created from data received by the communication device or the like is synthesized.

[0003]

According to the present invention, a singer singing in karaoke is imaged and displayed in real time between the "background image display" and the "lyric subtitle display" on the screen of the conventional device. And propose a system that can appear on the screen.

[0004]

SUMMARY OF THE INVENTION Among karaoke apparatuses with video display, video processing for displaying lyrics subtitles (internal processing for synthesizing lyrics subtitle display with background video) is performed independently of background video. Assume a system that can do it. As shown in FIG. 3, an image pickup system (such as a CCD camera) is connected between a background video reproduction device (or a circuit for reproduction) and a device for synthesizing lyrics subtitle display (or a circuit for synthesis). Inserted image synthesizing device (or circuit for synthesizing). (However, if the display portion of the image synthesis can be specified and synthesized so as not to disturb the lyrics subtitle display on the screen by a control signal or the like, the video synthesizing device is not necessarily connected to the background video playback device and the lyrics subtitle display device. It is not necessary to connect the “intermediate”, and in this case, a method of connecting the synthesizing device to another connection point is also included in claim 1.) Further, “the image synthesizing device connected to the imaging system” Figure 5
In the configuration as shown in (1), synthesis of replacing a specific color portion such as blue in the video input to the video input B with the video input to the video input A (chroma key synthesis)
Or brightness above a certain level (or brightness below a certain level)
A device for performing synthesis (luminance key synthesis) for replacing the portion with the video of video input A is used. For example, in the case of chroma key synthesis using blue, a blue background (screen sheet or wall, etc.) is imaged behind the singer using a white or black background behind the singer in the case of luminance key synthesis. It is necessary. Thus, it is possible to arrange the apparatus as shown in FIG. 6 and make a singer singing in front of a background for synthesis (a screen sheet or a wall of a fixed color, for example) be synthesized and appear on a video in real time. (However, the position of the device is not limited to the position configuration shown in FIG. 6, but may be any position configuration that can image the singer.) The above is the content of claim 1.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIGS. 3, 5, and 6, each device is constructed and connected for use.

[0006]

According to the system described above, in the video screen of the karaoke apparatus, the front side of the background video and the rear side of the lyrics subtitle (portion other than the lyrics subtitle display in the screen).
In addition, the singer singing in karaoke can be imaged and synthesized and displayed on the screen in real time.
(FIG. 4) Further, by connecting to a video printing machine (such as a video printer), the synthesized singing video can be immediately printed as a photograph.

Claims (1)

[Claims] 1. A karaoke apparatus capable of processing a video image for displaying lyrics subtitles independently of a background video among karaoke apparatuses with video display, and a background video playback apparatus (or a playback circuit). ) And a device for synthesizing the lyrics caption display (or a circuit for synthesizing), by inserting a video synthesizing device (or a circuit for synthesizing) connected to an imaging system (such as a CCD camera), In the video screen, the singer who is singing in karaoke can be imaged and displayed on the screen in front of the background image and behind the lyrics subtitle (the part other than the lyrics subtitle display in the screen). system
