A configuration may be used in which one is selected and used. Thereby, it is possible to define the movement of the character corresponding to the pronunciation in accordance with the image of the song.
[0013]
2: Operation Next, the operation of the karaoke apparatus according to the present embodiment will be described. First, when a user who is a singer operates the operation panel SW to select a desired karaoke performance song, the CPU 10 sends the song data of the performance song via the modem 13 and the telephone network N to the host station. 20 to request. Upon receiving such a request, the host station 20 searches for the corresponding song data and transfers it to the karaoke apparatus as the terminal station. When detecting this reception, the CPU 10 loads the music data onto the RAM 12.
[0014]
At this time, the CPU 10 sets time data t _i ′ indicating time that is preceded by half of the period indicated by the period data w _i before the time indicated by the time data t _i of the lyrics control data in the song data. Each time data is obtained. Thereafter, when a performance start instruction is executed via the panel switch SW or the like, the CPU 10 executes the following processing.
[0015]
First, the CPU 10 executes processing related to performance data. That is, the CPU 10 performs an interrupt process 24 times for each quarter note of the performance music, and decrements the duration data of the performance data by “1” each time the interrupt process is performed once. Here, the duration data becoming “0” indicates that the progress of the performance has reached the timing for performing the processing corresponding to the next event data, and therefore the CPU 10 corresponds to the event data. The process to do is performed.
[0016]
For example, if the event data is a note-on event, the data is transferred to the sound source circuit 15. As a result, the tone generator circuit 15 generates a tone defined by the note-on event data.
Then, after executing the process corresponding to the event data, the CPU 10 reads the value of the duration data arranged next to the event data to prepare for the next event.
On the other hand, the fact that the duration data is not “0” indicates that the progress of the music has not yet reached the timing at which the processing corresponding to the next event data is to be performed. Therefore, the CPU 10 performs some processing regarding the performance. Absent.
The CPU 10 executes such processing for each track.
[0017]
As described above, since the performance based on the performance data proceeds by the activation of the interrupt process, the time from the performance start point can be obtained by counting the number of times the interrupt process is activated.
[0018]
Next, secondly, the CPU 10 executes processing related to the lyrics display data. That is, the CPU 10 refers to the data indicating the timing among the various data included in the lyrics data, and when the progress of the performance reaches the timing, the CPU 10 transfers the data relating to the lyrics display to be performed at the timing to the video circuit 18. . On the other hand, the DSP of the video circuit 18 rewrites the V-RAM in accordance with the contents specified in the transferred data.
Thereby, the lyrics including the progress of performance are displayed on the monitor 19.
[0019]
Thirdly, the CPU 10 executes processing related to the lyrics control data. That, CPU 10 refers to the time data _{t i} and duration data _{w i} and the time data _{t i} was determined by the lyric control data _{'(t i' = t i} -w i / 2), the progression of playing the timing Once reached, the lyrics text according to the time data t _i, to rise from the other characters, controls the video circuit 18. If the character is separated from another character by a distance corresponding to the volume data h _i at the time indicated by the time t _i , the video is then returned to the other character in the downward direction. The circuit 18 is controlled. Furthermore, the CPU 10 controls the video circuit 18 so that the moving speed of the character when rising or falling follows a normal distribution curve (see FIG. 4) obtained from the period data w _i and the volume data h _i .
On the other hand, the DSP of the video circuit 18 rewrites the V-RAM according to the control content of the CPU 10.
[0020]
Thus, the time the character to be sounded in indicated by the time data t _i, only from the previous time half the time indicated by the time data w _i than that time, gradually began to rise to other characters, time at a time indicated by the data t _i, a distance corresponding to the volume data h _i, then returns to the other characters, after only half of the time indicated by the time data w _i than the time indicated by the time data t _i Is displayed on the same line as other characters.
That is, if the lyrics control data is as shown in FIG. 3, the lyrics displayed on the monitor 19 are as shown in FIGS. 5A to 5E at times t _{1 to} t ₅ , respectively.
[0021]
According to the karaoke apparatus of such an embodiment, the displayed lyrics not only indicate the progress of the performance, but also the volume to be pronounced and the period to be pronounced. There is an advantage that it is not difficult and contributes to the excitement of the atmosphere.
[0022]
3: Modification In the present embodiment, the character to be pronounced is displayed separately from the other characters to indicate the timing of the pronunciation of the character. At this time, the character is displayed as a polygon. A three-dimensional feeling may be given. At this time, it is possible not only to rise and fall, but also to give the phonetic character a feeling of floating by giving a slight vibration to the pronunciation character.
Further, in the present embodiment, the sound volume of characters is indicated by the distance away from other characters, but the present application is not limited to this. For example, the distance from other characters may be fixed, and the size of the character may be displayed in proportion to the sound volume.
[0023]
【The invention's effect】
As explained above, according to the present invention, the displayed lyrics not only indicate the progress of the performance but also the volume to be pronounced, so that it is not difficult for a singer to sing even an unknown song, In addition, it is possible to contribute to the excitement of the atmosphere .
