Abstract

PURPOSE: To guide correctly for a singer by successively executing coloring processing with a coloring means according to a division dividing a display picture of a character. CONSTITUTION: The character showing the lyrics is subdivided to plural divisions J1 to J24 in the arrangement direction of the character, and the coloring processing is performed by the coloring means 17B successively according to the divisions J1 to J24 , and a waiting time is provided whenever the coloring of each division is performed. Then, the waiting time is shortened when occurrence frequency of guide timing is more (the number of characters showing the lyrics are more), and the waiting time is prolonged when the occurrence frequency is less (the number of characters showing the lyrics are less), and the processing speed of the coloring means 17B is changed. Thus, since the coloring is performed at high speed when the number of characters is more, and the coloring is performed at low speed when the number of characters is less, the position of the lyrics is displayed smoothly.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke lyrics guide device used in a karaoke device.

[0002]

2. Description of the Related Art Conventionally, a display device has been prepared for a karaoke device, and the lyrics are displayed on the display device, and the characters and symbols representing the lyrics are colored to indicate the singing position. The function to guide is added. The karaoke device is roughly classified into a system in which a live performance is stored in a storage medium such as a laser disk, and a system in which musical score data obtained by digitally encoding a musical score is given to a sound source device and a musical tone signal is generated by the sound source device to play karaoke. There is.

[0003]

Although any type of karaoke apparatus is equipped with a singing guide function, there is a deficiency in coloring for guiding the lyrics position. That is, in general, one character is colored at each singing timing to guide the singing position, or the character is gradually colored from the end in accordance with the progression of the tune to guide the singing position. When the characters are colored one by one according to the progression of the song, there is a drawback that the progress of the song is not smooth and does not act as a good guide for the singer.

A method of subdividing a character in order from the end and coloring the color is also in practical use, but in this case also, there is a disadvantage that the speed of coloring is not synchronized with the progression of the music. That is, in a karaoke device using a laser disc or the like, the lyrics are manually colored and recorded in a storage medium. For this reason, the timing of coloring may slightly change depending on the maturity of the operator who colors the lyrics, and there is a drawback that it does not act as a good guide. Further, in the method using the laser disk, the performance time has to be the same as that of the live performance, and the work of coloring the characters must be performed, which is disadvantageous in that it takes time.

Further, in the case of a format in which musical score data is given to the sound source device to play karaoke, when a method of coloring one character in order from the end is adopted, since the coloring is performed at a constant speed by the guide timing, the lyrics while the song is in progress There is an inconvenience that the coloring position and the lyrics position do not match in the part with many characters and the part with few characters. SUMMARY OF THE INVENTION An object of the present invention is to provide a lyrics guide device for karaoke in which the coloring speed changes smoothly in accordance with the change of music and the singer can be correctly guided.

[0006]

According to the present invention, in a karaoke apparatus of a system in which sound source operation data is given to a sound source device and a tone signal for karaoke is generated by the sound source device, characters representing lyrics displayed on a display device are vertically displayed. Alternatively, a dividing unit that divides the image into a predetermined number in the horizontal direction, a coloring unit that performs coloring for each division divided by the dividing unit, and a number of times that the guide timing occurs each time the guide timing occurs The guide counter performs control to reduce the stored content each time the means executes the coloring of the first divided section of the character, and the waiting time is reduced in the state where the content of the guide counter stores the occurrence of the guide timing. Is changed to the next color division and the guide counter is memorized to indicate that no guide timing has occurred. Are those configured by adding a weight counter by changing the waiting time in the increasing direction to perform the coloring of the next divided segment.

According to the configuration of the present invention, the characters representing the lyrics are subdivided one by one in the vertical or horizontal direction, and the subdivided subdivisions are colored for each subdivision. By controlling the repetition speed of coloring to increase or decrease depending on the occurrence of singing timing, the state in which characters are colored changes continuously, and the singing position is expressed in accordance with the progression of the song. be able to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the structure of a karaoke apparatus to which a song guide apparatus according to the present invention is added. In the figure, 1 indicates a memory. The memory 1 is composed of, for example, a semiconductor memory, and music data A, DAT and lyrics data B, D are stored in the semiconductor memory 1.
AT is written. The song data A, DAT and the lyrics data B, DAT may be written and prepared in the memory 1 in large numbers, or may be called and written from an external storage device such as a floppy disk or a hard disk as needed.

In any case, the song data A and DAT and the lyrics data B and DAT of the song to be sung are read from the memory 1, and the song data A and DAT are loaded into the first controller 2. The first controller 2 generates sound source operation data for each tempo clock according to the time management information in the music data read from the memory 1, and stores the generated sound source operation data in the buffer memory 3. At the same time, the data amount of the generated sound source operation data is stored in the buffer memory 4.

The second controller 5 controls the buffer memory 4 according to the tempo clock given from the tempo clock generator 6.
The data amount stored in is read out, and this data amount is transferred to the sound source control device 8 via the third controller 7. The sound source control device 8 reads the sound source operation data for the transferred data amount from the buffer memory 3, controls the sound source device 9 by this sound source operation data, and reproduces a musical sound. That is, the sound source device 9 includes, for example, sound source circuits of 8 to 16 channels. Each sound source circuit is set to generate sounds of various musical instruments. The sound source operation data stored in the buffer memory 3 is provided with data for designating a musical instrument. The tone generator circuit is selected by this instrument designation data, and the sound of each instrument is generated by the tone generator operation data. The generated musical tone signal is input to the loudspeaker 11, and is emitted as a sound by the loudspeaker 11.

The lyrics control device 12 has the same amount of lyrics data B and DA as the sound source operation data stored in the buffer memory 3.
T is read and the display memory 1 is displayed via the display controller 13.
Stored in 4. The lyrics data stored in the display memory 14 is given to the display device 15, and the lyrics corresponding to the portion of the musical sound generated by the tone generator 9 is displayed on the screen. The character pointer 16 operates to specify a character to be colored.

The description so far is the same as that of the conventional karaoke apparatus. The feature of the present invention is that the lyrics control device 1
2, a dividing means 17A, a guide counter 18 and a weight counter 19 are provided, a buffer memory 21 is provided in association with the first controller 2, and a third controller 7 is provided in addition. It is characterized by a configuration provided with a delay memory 22.

The dividing means 17A performs an operation of dividing the character representing the lyrics in the arrangement direction of the character. For example, when the lyrics are written horizontally, the character display area is horizontally divided into, for example, 24 division sections J _{1 to} J _{24 as shown} in FIG. Coloring means 17B starts operating to sequentially colored split segment J ₁ through J ₂₄ if the contents of the guide counter 18 is "1" or more.

That is, the guide timing indicating the singing position is generated as one of the sound source operation data generated by the first controller 2. The number of occurrences of this guide timing is counted, and the count value is stored in the buffer memory 21. The second controller 5 controls the buffer memory 21 according to the tempo clock output from the tempo clock generator 6.
Is read out and the number of occurrences of guide timing is added to the guide counter 18. At this time, if the content of the guide counter 18 is equal to or larger than "1", the waiting state of the lyrics control device 12 is released, and the coloring means 17B starts the coloring process of the lyrics.

In the coloring process, coloring is performed from the _first division section J ₁ of the character designated by the character pointer 16.
It should be noted that if there is no character dot in the division, coloring is not performed. That is, only the dot portion of the character is colored from white to yellow, for example. When the coloring of the _first divided section J ₁ is executed, the content of the guide counter 18 is controlled in the decreasing direction. That is, -1 is added. Weight counter 19
Gives a waiting time of, for example, 15 ms each time coloring of divided sections is completed. Here, the weight counter 19 refers to the content of the guide counter 18, and if the content of the guide counter 18 is "0", the waiting time is +1 ms, and if the content of the guide counter 18 is "1" or more, the waiting time is-. 1
Set to ms.

The contents of the guide counter 18 are the first division
Category J₁Since it was -1 while the coloring of
It is “0”. Therefore, the second and subsequent divisions
J₂, J ₃, J_FourThe waiting time is likened to each time you color ...
For example, 16ms, 17ms, 18ms ... gradually increase by + 1ms
Be added. An upper limit is set for the waiting time. For example above
If the limit value is 30ms, it will be twice as long as the initial 15ms.
Therefore, the coloring speed is reduced to 1/2.
The coloring of one character is completed as it is, and the coloring of the next character is completed.
If the guide timing does not occur when starting, wait
The time is inherited as it is and the next character is colored.

A guide timing occurs in the state where characters are being colored, and the guide counter 18 is set to "1".
When is written, the weight counter 19 reduces the waiting time by -1 ms each time the divided sections are colored. Therefore, the coloring speed is increased and the coloring process is executed at a high speed. The lower limit value of the waiting time is set to, for example, 7 ms, and the waiting time is limited so as not to be less than 7 ms. As a result, the speed of the coloring process changes in the range of 7 ms / 1 division to 30 ms / 1 division centering on the 15 ms / 1 division.

FIG. 3 shows the relationship between the musical notation, the displayed lyrics, the tempo clock and the guide timing. FIG. 3A shows a musical score. Each musical notation symbol shown in this musical notation is digitally encoded, converted into a digital code corresponding to a note name, a note length, and a musical instrument, and stored in the memory 1. 3B shows the lyrics displayed on the display device 15, FIG. 3C shows the tempo clock, and FIG. 3D shows the guide timing. The second controller 5 controls the buffer memory 2 according to the tempo clock shown in FIG. 3C.
Read the contents of 1. When the guide timing is written in the buffer memory 21, the number of occurrences of the guide timing (normally 1) is additionally written in the guide counter 18. Guide counter 1 when the guide timing occurs continuously
The contents of 8 are sequentially added. Therefore, the guide counter 18
The coloring processing speed is kept high until the content of the item returns to "0", and the characters of the displayed lyrics are colored at high speed.

By the way, in the present invention, as shown in FIG. 2, the character display screen is divided into a plurality of divided sections J _{1 to} J ₂₄ , and the coloring means 17B is sequentially operated according to the divided divided sections J _{1 to} J _24. Since it is configured to execute the coloring process,
There is an inconvenience that the timing of starting the coloring of characters does not match the timing of sound generation. Therefore, in the embodiment shown in FIG. 1, a delay memory 22 is provided in association with the third controller 7, and the sound source operation data transmitted from the sound source control device 8 to the sound source device 9 is transmitted by the delay memory 22. The timing is delayed so that the characters start to be colored and the sound generation timing is matched.

[0020]

As described above, according to the present invention, the character representing the lyrics is divided into a plurality of divided sections J in the character arrangement direction.
_It is subdivided into _{1 to} J ₂₄ , and coloring processing is sequentially performed by the coloring means 17B in accordance with the divided sections J _{1 to} J ₂₄ , and
A waiting time is provided each time the divided sections are colored, and this waiting time is shortened when the guide timing occurs frequently (when the number of characters representing the lyrics is large), and when the guide frequency is low (the lyrics are When the number of characters is small), the waiting time is lengthened and the processing speed of the coloring means 17B is changed. When the number of characters is large, the coloring is performed at high speed, and when the number of characters is small, the coloring is performed at low speed. The position can be displayed smoothly.

Further, since the sound source operation data is delayed so that the character coloring start timing and the sound generation timing coincide with each other, the singing start timing coincides with the character coloring start timing, and a karaoke device which facilitates singing is constructed. be able to.
