JP2989206B2 - Synchronization change creation device for lyrics in karaoke - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a karaoke apparatus, which is a simple apparatus that converts data for sequentially changing the color of lyrics displayed on a display in synchronization with the progress of music. Related to technologies that can be easily created.

[Conventional technology]

Generally, in a karaoke apparatus, lyrics are displayed on a display at the same time as karaoke music is reproduced via a speaker. For the convenience of the singer, a means of sequentially changing the color of the lyrics in synchronization with the progress of the music is adopted.

By the way, the applicant uses a conventional PCM as a karaoke device.
Rather than recording, data is created with complete binary code as computer information, this is processed and music is played back, and a method of displaying lyrics is invented, and many related applications have been filed. (For example, Japanese Patent Application No. 64-308503)
No., Japanese Patent Application No. 1-3086, Japanese Patent Application No. 1-5793, Japanese Patent Application No. 1-86
No. 11298).

Even in this case, it is necessary to change the color of the lyrics in synchronization with the progress of the music, but as a configuration, if the color change timing is input as a logical value, data can be obtained from the main melody without using a complicated dedicated device. Can be created. However, this method has a problem in that it takes too much production time to change the lyrics color because all of the information about the change timing and the progress of the lyrics display must be input from an input device such as a keyboard. In addition, if the progress of the music and the deviation occur when actually displayed on the display, it is difficult to determine the correction portion of the data, and there is a defect that much more time is required for the search. .

An object of the present invention is to solve the above-described problem, and an object of the present invention is to provide a technique capable of easily creating data relating to lyrics color change by using a simple device.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a music playback device (2), a lyrics display device (7), a touch panel (9), a timing data generator (11), and a timing storage device (12). In the apparatus for synchronizing and changing lyric colors in karaoke composed of a guide rail (10), a music reproduction dedicated device (2) reads out music information composed of performance information and time information stored in a storage means (1), The performance information is output to a sound source (3), and a synchronizing signal created based on time information is output to a timing data generator (11).
Reads the lyrics information stored in the display (8)
And changes the color of the displayed lyric information based on the change timing data.
Is provided on the surface of the display (8), and outputs the coordinate value of the pressed point. The timing data generator (11) converts the synchronization signal from the dedicated music playback device (2) and the coordinate value from the touch panel (9). It inputs and outputs the count number of the synchronization signal for each predetermined coordinate value as change timing data to the lyrics display dedicated device (7) and the timing storage storage device (12). The guide rail (10) is connected to the display (8) surface. Is provided corresponding to the lyrics display position.

[Action]

The karaoke information is composed of binary codes. The karaoke information is composed of performance information relating to the strength and timbre of the sound, music information comprising time information relating to the performance time, and lyric information which is character information. The music reproducing means processes music information, transfers data to performance equipment such as a sound source, and outputs a synchronization signal to a timing data generator. This synchronization signal is generated from time information for time management of music reproduction, and is a pulse-like waveform output at a constant frequency.

The lyrics display means performs a function of, for example, performing character processing on the lyrics information and displaying lyrics corresponding to music reproduction on a display surface. A touch panel is provided on the upper surface of this display, but by tracing the lyrics with a finger or a writing instrument in accordance with the music playback from this touch panel, the press is detected and the coordinates are numerically converted to the timing data generator. Performs the function of outputting. The guide rail is provided at a position corresponding to the lyrics line, but has an effect of facilitating the tracking of the lyrics.

The timing data generator calculates the speed of the coordinate movement based on the two inputs of the synchronization signal and the coordinate value. That is,
In the present invention, the color of the lyrics string displayed on the display is changed in accordance with the music reproduction to obtain data capable of indicating to the singer who is currently singing.
For this reason, when tracing (tracking) the lyrics from the touch panel, the timing data generator calculates the distance from one lyric character to the next lyric character from the coordinate values of both characters, and calculates the number of synchronization signals existing between them. Is counted, and the distance is divided by the number of the synchronization signals to obtain the speed of the coordinate movement, thereby performing a function of time management of the transition of the lyrics color corresponding to the music reproduction. Therefore, the color of the lyrics displayed on the display can be changed based on the coordinate values and the number of synchronization signals.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, the data relating to the reproduction and lyrics display of karaoke music used in the present invention is composed of time information for the progress of the performance as the music information for reproduction, performance information defining the strength and tone of the sound, etc. It is composed of character information and page break information defining a character unit that can be displayed on one screen.

While processing and reproducing the data configured as described above, the lyrics displayed on the display are tracked while synchronizing with the performance to create data relating to the lyrics color change. FIG. In the figure, reference numeral 1 denotes a storage device which stores music information including time information and performance information. Reference numeral 2 denotes a music reproduction device that reproduces music information extracted from data stored in the storage device and outputs a performance signal serving as a reference for creating lyrics synchronization data. The dedicated device 2 simultaneously outputs a synchronizing signal that can be distinguished separately from the performance signal during reproduction. The synchronization signal is output in accordance with the time information, and the time information has a timing of 1 / 24th of a quarter note. Further, the synchronization timing of the lyrics described later is calculated by counting the synchronization signal. A start signal and a stop signal are also output to notify the start and end of the reproduction. Reference numeral 3 denotes a sound source driven by a performance signal, 4 denotes an amplifier for amplifying an audio signal from the sound source, and 5 denotes a speaker. Reference numeral 6 denotes a lyrics storage device, in which lyrics corresponding to the contents of the storage device 1 are stored as data, and an original screen for synchronization is displayed on the display 8 by a lyrics display device 7. The target lyrics screen is once read into the memory of the dedicated lyrics display device 7 and is displayed.
If a lyrics tracking operation is performed from above, a monitor function of displaying the lyrics on the display 8 while changing the lyrics color accordingly is also performed. 2, the display 8 includes a touch panel 9 on the display surface, and guide rails 10a and 10b provided in a portion where the lyrics are displayed in correspondence with the lyrics row. The reason for using two guide rails is that lyrics display is scheduled for two lines. If only one line of lyrics is to be displayed, one guide rail is sufficient.

Next, reference numeral 11 denotes a timing data generator, which is a grid when the coordinates of the lyrics being pressed on the touch panel 9 provided on the display 8 surface are composed of 24 horizontal dots by 32 vertical dots, and a pressing position. Is always monitored as an intersection,
A lyrics color transition speed is calculated from the distance from one lyric character to the next lyric character and its time coefficient, and this transition speed data is used as lyrics color change timing data together with the lyrics color change instruction data as lyrics display dedicated device 7. Are arranged in the internal memory. Therefore, the dedicated lyrics display device 7 that has received the transition speed data and the lyrics color change command data changes the color of the lyrics displayed on the display 8 based on this information. The time coefficient is the count number of the synchronizing signal. If the lyric sequence is quickly traced, the number of synchronizing signals existing during this period is small, while if the tracing is slow, the number of synchronizing signals increases. This is the basis for creating color change timing data. The migration speed data on the memory generated in this way is stored in the timing storage storage device 12. Reference numeral 13 denotes the concept of scanning coordinates by operating the touch panel 9.

In order to create the lyrics color change timing data with such a configuration, first, an arbitrary music piece is designated from the storage device 1, data relating to performance is processed by the music reproduction device 2, and the sound source 3 generates the audio signal as an audio signal. Start playback. Then, the lyrics corresponding to the song are loaded from the lyrics storage device 6 into the lyrics display device 7 by the start signal and displayed on the display 8, so that the operator can listen to the music while listening to the music so as to correspond to the guide rail. The lyric sequence is tracked from the touch panel 9 surface along fingers 10a and 10b with a finger or a pencil. Then, the coordinates of the touch panel 9 are determined, and the timing data generator 11 sequentially counts the synchronization signals falling within the time interval within the tracking range to determine the color change time for each character. As a more detailed process, if the color change time for each character is determined, the time can be divided into 24 horizontal dots, and the color can be gradually changed for each character from the left. . For example, if the number of characters continuously displayed on one screen is 24, if a page break signal is automatically written for every 24 characters, the page change process can be performed simultaneously with the color change process.

FIG. 3 shows the internal configuration of the timing data generator 11. A CPU 14 performs arithmetic processing of change timing data from the coordinates and the count number of the synchronization signal.
Decoder for detecting scans, 16 is a serial interface for receiving performance information, 17 is an output port for triggers such as lyrics color change instruction data and a page break signal for lyrics screen, 18 is internal memory, and 19 is storage The control device 20 of the device 12 is a timer for periodically checking the decoder 15, and connects this output to the interrupt terminal of the CPU 14.
The data sequence obtained in this way is temporarily stored in the storage device 12, merged with the performance information, reconstructed as performance information including a new synchronizing signal of lyrics, and all the processes are completed.

〔The invention's effect〕

In the present invention, when creating the lyrics color change data, it is possible to take the timing of changing the lyrics color only by tracking the corresponding characters of the lyrics displayed on the display while playing and listening to the music, Synchronization processing, which was difficult in the past, can be performed very easily.

In addition, after the change timing is created, it can be merged with the original performance information to form new performance information, so that the lyric color change processing that accurately corresponds to music reproduction can be performed.

Furthermore, since the quarter note used in the actual performance is used instead of the absolute time as a reference for creating the timing, the correspondence between the performance time and the lyrics color change timing is relatively simple, and the data amount is suppressed. Such as
A device having many effects could be provided.
