The display device 3 is, for example, a CRT display device, and the display device 3 is, for example, a background image of a music piece. And a singing part such as a lyrics telop or other information can be displayed on the display screen. The remote controller 4 as an operation means includes a plurality of key switches and the like, generates an operation signal according to the operation of the user, modulates an infrared signal corresponding to the operation signal, and modulates the image control unit 2. Radiation.

The video control unit 2 includes a CPU 21, an interface control unit 22, a memory 23, an internal video signal generation circuit unit 24, an input video signal processing circuit unit 25, a picture-in-picture control circuit unit 26, and a video signal switching circuit. And a remote control light receiving unit 28. Then, the CPU 21 controls these interface control units 2.
2. A bus line is connected to the memory 23, the internal video signal generation circuit 24, the input video signal processing circuit 25, the picture-in-picture control circuit 26, the video signal switching circuit 27, and the remote control light-receiving unit 28. These components are electrically connected to each other, and the entire image control unit 2 can be controlled by appropriately controlling these components. The interface control unit 22 includes a CPU 21
And is connected between the karaoke apparatus main body 1 and functions as an interface between the CPU 21 and the karaoke apparatus main body 1. The memory 23 connected to the CPU 21 is, for example, a RAM or the like, and stores various data and is also used as a working memory of the CPU 21. The internal video signal generation circuit 24 controlled by the CPU 21 is, for example, a hard disk (HDD).
A video signal for displaying various information (second video) such as the latest ranking of hit songs in various genres and karaoke reserved songs is output to the picture-in-picture control circuit unit 26. . Also, C
Input video signal processing circuit 2 controlled by PU 21
5 processes a video signal from the karaoke apparatus main body 1 and converts the signal into a picture-in-picture control circuit 2
6, the video signal switching circuit 27 can be directly output without passing through the picture-in-picture control circuit 26.

Only one horizontal line of the video signal from the input video signal processing circuit unit 25 to be a sub-screen is valid for every two lines, and it is stored in the memory 23, and is converted into an internal video which becomes the main screen at double speed. It is read out in synchronization with the video signal from the signal generation circuit section 24, and is superimposed on a sub-screen display portion for the main screen. In this case, since the child screen is displayed by compressing the original screen, the resolution is lower than the original video, and the singing part such as the lyrics telop is displayed on the display screen as small and crushed. It is difficult for singers to sing.

The remote control light receiving section 28 for receiving the remote signal emitted from the remote controller 4 has a C
The CPU 21 is connected to the PU 21, and the CPU 21 stores a signal corresponding to an operation content for the remote controller 4 in the memory 2.
3 or the interface control unit 22 and the CPU 21 stores the information content corresponding to the signal as a flag in the memory 23 or the interface control unit 2.
2 can be output to the karaoke apparatus main body 1. When the user wants to prohibit the switching of the display state of the display screen at the time of displaying the singing portion of the lyrics telop during the performance of the display device 3, the user performs a predetermined operation on the remote controller 4. Specifically, the user performs a predetermined operation on the remote controller 4, and the operation signal is transmitted to the CPU via the remote control light receiving unit 28.
The CPU 21 causes the memory 23 to store a flag for prohibiting screen switching when a singing portion such as a lyrics telop is displayed during a performance.

In this embodiment, the user can arbitrarily select one of the karaoke mode and the screen switching mode via the remote controller 4 in the initial setting mode. ing. This karaoke priority mode is a non-divided screen by the user while the singing section such as the lyrics telop is displayed on the display screen, except for the interlude and the after-play after the start of the singing section display such as the lyrics telop after the karaoke prelude. This is a mode in which a request for switching from the (first display state) to the split screen (second display state) is ignored. On the other hand, the screen switching mode is a mode in which the user follows a screen switching request of the display screen regardless of whether or not a karaoke performance is being performed. of course,
In the karaoke priority mode according to another embodiment, the display screen of the display device 3 is divided into two screens at the start of the karaoke performance (the second screen).
Display state), the screen is forcibly switched to the non-split screen (first display state), and the singing unit such as the lyrics telop is displayed on the display screen except for the interlude and subsequent performance. The mode may be such that a request for switching from a non-split screen (first display state) to a split screen (second display state) by a user is ignored.

Next, the operation of the karaoke apparatus thus configured will be described. First, when the user operates the remote controller 4 and inputs an instruction to switch the display state before starting the display of the singing part such as the prelude of the performance music, that is, the lyrics telop, the remote controller 4
And, via the remote control light receiving unit 28, the operation signal is CP
The signal is input to U21, and the CPU 21 switches the state of the video signal switching circuit unit 27. That is, the CPU 21 allows the video signal switching circuit unit 27 to input the video signal from the input video signal processing circuit unit 25 without passing through the picture-in-picture control circuit unit 26 and output the video signal to the display device 3 as it is. In this state, the video signal from the picture-in-picture control circuit 26 is input to the video signal switching circuit 27 and is output to the display device 3 as it is. On the contrary, the CPU 21 switches the video signal from the input video signal processing circuit 25 to the video signal switching from the state where the video signal from the picture-in-picture control circuit 26 is being output to the display device 3. The state is switched to a state of outputting to the display device 3 via the circuit section 27.

Then, the user operates the remote controller 4
When the tune number of the requested tune is input to the karaoke apparatus main body 1 through the remote control light receiving unit 28, the CPU 21 and the interface control unit 22, the karaoke apparatus main body 1 outputs the requested tune number. Is the input video signal processing circuit 2
5 and the display device 3 via the video signal switching circuit 27.
At the same time, the performance of the requested music is started, and the process proceeds to the prelude. As the music progresses, singing part data such as display lyrics telop data, which is stored in advance in synchronization with the music data, is input to the input video signal processing circuit 25, and the display screen of the display device 3 displays A singing part such as a background image of the song and a lyrics telop is displayed. Note that C
The PU 21 monitors a signal from the karaoke apparatus main body 1 input to the interface control unit 22, and can detect a singing start signal input together with the singing unit data.

Thereafter, when the display of the singing part such as the lyrics telop is finished, the CPU 21 can detect the singing end signal of the singing part inputted together with the singing part data by the interface control part 22. As a result, if the singing end signal of the singing portion is input to the interface control unit 22, the CPU 21 operates the video signal switching circuit unit 27 to switch the display state in the same manner as before the start of the lyrics telop display. be able to. When the singing end signal of the singing portion is input to the interface control unit 22, the interlude is performed in the middle of the music piece, and the interlude is the last part of the music piece. However, as another embodiment, in the case where a signal for detecting the singing part in the music data is not provided, the start of the lyrics telop after the prelude is detected, and then the singing of the lyrics telop or the like is performed. If the non-display of a part continues for a certain regular interval, for example, one bar, it may be regarded as an interlude or a follow-up, and the setting of the switching of the display state may be changed as described above.

When the user operates the remote controller 4 to input an instruction to switch the display state at the time of displaying the singing section such as the lyrics telop during the performance, the operation is performed as described above. The signal is sent from the remote controller 4 to the CPU
In this case, the CPU 21 checks whether or not an operation content flag for prohibiting screen switching when a singing part such as a lyric telop being played is displayed is stored in the memory 23. If a flag indicating that screen switching during display of a singing portion such as a lyrics telop is prohibited is stored in the memory 23 during the performance and the karaoke priority mode is set, the CPU 21 outputs the video signal. The switching signal circuit 27 is not controlled, and the switching instruction by the user is ignored. On the other hand, if the memory 23 does not store a flag for prohibiting screen switching when displaying a singing section such as a lyrics telop during a performance, that is, if the screen is in the screen switching mode, the lyrics telop or the like is displayed. The display state is switched in the same manner as before the start of the display of the singing unit.

Therefore, even if the next song is already reserved and the performance of the next song is started immediately after the performance of the current performance song is completed, the prelude until the singing part such as a lyrics telop is displayed is started. The user can freely switch the display state of the display screen of the display device 3 by operating the remote controller 4. Thereby, as shown in FIG.
The display device 3 can display a display state in which the child screen composed of the first video screen is fitted to the main screen that displays information such as the latest hit song ranking and karaoke reservation songs.

Next, the procedure of the above-described screen switching process will be described with reference to the flowchart shown in FIG. This screen switching process is executed by the CPU 21 at predetermined times. First, it is determined whether or not a switching instruction has been issued from the remote controller 4 (S1). Specifically, the CPU 21 monitors the signal from the remote control light-receiving unit 28 so that the user performs an operation for switching the display state of the display screen of the display device 3 on the remote controller 4, and the signal is Check whether it has been entered.

When the CPU 21 inputs a signal for switching the display screen (S1: YES), it is determined whether or not the karaoke mode is the priority mode (S2). Specifically, CPU 2
1 checks whether or not a flag indicating that the karaoke priority mode has been selected is stored in the memory 23. If the mode is not the karaoke priority mode (S2: NO), the CPU 21 directly proceeds to S4 without proceeding to S3 in order to comply with the screen switching request by the user. In the karaoke priority mode (S2: Y
ES), it is determined whether a singing unit such as a lyrics telop is being displayed on the display screen (S3). Specifically, CPU 2
1 monitors a signal from the karaoke apparatus main body 1 input to the interface control unit 22 and ends the singing unit display after a singing start signal for starting singing unit display such as lyrics telop is input. It is checked whether the singing end signal to the effect is not input. This can be easily realized, for example, by storing a flag in the memory 23.

If the display screen is not displaying a singing part such as a lyrics telop (S3: NO), the CPU 21 determines whether or not the display screen is a split screen (second display state) (S4). Specifically, the CPU 21 checks whether the video signal switching circuit 27 outputs a video signal from the picture-in-picture control circuit 26 to the display device 3. If the display screen is the split screen (second display state) (S4: YES), the CPU 21 sets the non-split screen (first display state) to comply with the screen switching request by the user.
(S5), and terminates this routine. Specifically, the CPU 21 controls the video signal switching circuit unit 27 to switch the display screen of the display device 3 from the divided screen (second display state) to the non-divided screen (first display state). If the display screen is not the split screen (the second display state) (S4: NO), the display screen is switched to the split screen (the second display state) in order to comply with the screen switching request by the user (S6), and this routine is performed. To end. Specifically, CP
U21 controls the video signal switching circuit unit 27 to switch the display screen from the non-divided screen (first display state) to the divided screen (second display state). In S3, if a singing section such as a lyrics telop is displayed (S3: YES),
This routine ends. In other words, even if the user issues a switching instruction, the karaoke mode is set, and the display state of the display screen of the display device 3 is changed to the non-divided screen (first display state) when the singing section such as the lyrics telop is displayed. ) Is not switched to the split screen (second display state). Then, by ignoring the user's request for switching from the non-split screen (first display state) to the split screen (second display state), the singing unit such as the lyrics telop on the display screen is maintained in an easily viewable state. .

In S1, if there is no instruction to switch the display screen from the remote controller 4 (S1: NO), the CPU 21 checks in the same manner as in S3 whether it is a singing part such as the lyrics telop (S7). . If it is a singing unit such as a lyrics telop (S7: YES) and the display screen is a divided screen (second display state) (S8: YES), the display is switched to a non-divided screen (first display state) ( S9), this routine ends. That is, the CPU 21 controls the video signal switching circuit unit 27 to change the display screen of the display device 3 from the divided screen (second display state) to the non-divided screen (first display screen).
Display state). Specifically, after the performance music starts, a singing section such as a lyrics telop is displayed on the display device 3, and when the display screen is a split screen (second display state), the non-split screen (first display screen) is automatically displayed. (Display state) to make it easier to see the singing part such as the lyrics telop on the display screen.

In S8, the display screen is divided screen (second
If not (S8: NO), there is no need to switch the display state, so this routine is terminated. S
In 7, it is not a singing part such as a lyrics telop (S
7: NO), this routine ends. In the above-described embodiment, the split screen that can be switched during non-singing during performance and the split screen during non-singing are not distinguished, but split screens in different forms may be displayed. Further, as shown in FIG. 3C, the display of the first image in the divided screen at the time of the non-singing part during the performance is 倍 times in the vertical direction and 1 times in the horizontal direction, that is, the area is The display state may be set to 1/2 times. Specifically, in a mode in which the display screen is displayed in the vertical direction １ ／ and the horizontal direction ２, the picture-in-picture control circuit unit 26 sets the data of the first video to be the same as that of the second video. It can be realized by reading at the speed. It should be noted that the first video serving as a sub-screen is added to the above-mentioned 1 /
The display state may be four times the area.

Therefore, the video signal switching circuit unit 27 of this embodiment includes a first display state in which only the first image is displayed on the display screen of the display device 3 and a second display state different from the first image. Display device 3 by dividing a video and a first video into screens
And a second display state to be simultaneously displayed on the display screen according to a user operation. Further, the CPU 21 constitutes determination means for determining whether a singing part such as a lyric telop is being displayed during the performance of the performance music or whether it is a prelude, an interlude, or a subsequent performance in which the singer of the performance music does not sing. . If the CPU 21 determines that the singing section is being displayed during the performance, the CPU 21 switches the video signal switching circuit section 27 (display state switching means) from the first display state to the second display state. It constitutes a switching prohibition means for prohibiting. The remote controller 4 and the remote control light receiving unit 28 which receives infrared light from the remote controller 4 and outputs an operation signal corresponding to the infrared light to the CPU 21 determine whether or not to operate the CPU 21 (switching inhibition means). The operation means for selecting is configured. Further, the memory 23 constitutes storage means for storing the operation contents of the remote controller 4 and the remote control light receiving unit 28 (operation means).

As described above, according to the karaoke apparatus (musical sound generating apparatus provided with the singing display section control device) of the present embodiment, the singing section is displayed while the CPU 21 (determination means) is performing. When the video signal switching circuit 27 (display state switching means) determines that the first
Is switched from the display state to the second display state by the CPU 2.
Since 1 (switching prohibition means) prohibits, it is possible to eliminate the difficulty of the singer singing due to the switching of the display state of the singing unit such as the lyrics telop. That is, since the display of the background image of the musical piece being sung and the singing part such as the lyrics telop does not become small, the singing part such as the lyrics telop is easy to see, and the display of the background image of the musical piece and the singing part such as the lyrics telop is frequently performed. The singer can concentrate on singing because it does not grow or shrink. In addition, it is possible to switch from the first display state to the second display state when the singing part such as a lyric telop is not displayed, such as a prelude, an interlude, and a follower that the singer does not sing,
The user can see the information on the display screen in the second display state.

Further, as in the karaoke apparatus of the above embodiment, a remote controller 4 (operation means) for selecting whether or not to operate the CPU 21 (switching inhibition means).
And a memory 23 (storage means) for storing the contents of the operation by the remote controller 4, and the CPU 21 (switching inhibition means) stores the CPU 23 in the memory 23 (storage means).
When the operation content for operating the switch 21 (switching prohibition unit) is stored, the switching from the first display state to the second display state by the video signal switching circuit unit 27 (display state switching unit) is prohibited. And that is memory 23 (storage means)
Is not stored in the first display state, it is desirable to adopt a mode of switching from the first display state to the second display state, but the present invention is not necessarily limited to this mode. Further, as a karaoke apparatus (musical sound generating apparatus provided with a singing display section control device) according to another embodiment, a plurality of display apparatuses 3 are connected to a video signal switching circuit section 27 and a video signal switching circuit section 27 is connected. Is configured such that the display contents of the plurality of display devices 3 can be individually controlled, and the control device can simultaneously switch the display states of the display screens of the plurality of display devices 3 by one operation. One of them may be configured as the singer's display device 3 so that the display state is not switched during the singing.

Further, the present invention is not necessarily limited to the above-described embodiment, and other embodiments may be employed. For example, the singing display control device may be applied to a singing display control device other than the karaoke device. Further, the musical sound generating device may be a device other than the karaoke device as long as it generates music. Further, the second display state is such that if a second image different from the first image and the first image can be simultaneously displayed on the display screen by screen division, a child displaying the first image is displayed. Arbitrarily setting the size of the screen does not matter at all. Further, the singing unit may include a song other than the lyrics telop. Then, by appropriately devising the display form of the divided screen, the divided screen during the performance may be made easier to see than the divided screen during the non-performance. Further, at the time of non-playing, it is also possible to increase the number of selections of the user by adding, for example, a half-screen child screen to the type of the split screen. In addition, the content of the video on the display screen during non-singing during performance and the content of the second video serving as the parent screen of the split screen during non-performance may be changed. For example, the display screen for non-singing during performance displays information such as the karaoke song reservation status after the next, and the display screen for non-singing can display information such as the latest hit song ranking. It is.
