DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration when a music reproducing apparatus of the present invention is realized on a karaoke apparatus.

Before describing each block, a brief description will be given of the musical tone information in the present embodiment. In the present embodiment, MIDI (Musical Instrume
nt Digital Interface) information. MIDI
Is interface information for digitally communicating performance information of each musical instrument, which is an international standard (MIDI is a registered trademark).

Next, each block will be described. A performance information storage unit 12 and an image information storage unit 14 are connected to a control device 10 which is a central control unit of the present apparatus.

The musical tone information storage means 12 stores musical tone data 12a stored as MIDI information and lyrics display instruction data 12b relating to control of lyrics display. The image information storage means 14 stores the lyrics data 14
a and the background video data 14b are stored. These performance information storage means 12 and image information storage means 14
For example, it is constituted by a hard disk.

The control device 10 has a program memory 16 in which an operation program of the control device 10 is stored,
A monitor 28 for displaying lyrics and background images is connected. Further, a MIDI interface board 18 to which the musical sound data 12a is transmitted is connected to the control device 10, and the MIDI interface board 18 further includes:
The MIDI multi tone generator unit 20 is connected.

The MIDI multi tone generator unit 20 comprises:
For example, it is composed of a synthesizer, etc.
Based on the data sent from the interface board 18, electronic music signals of various instrument sounds are synthesized and supplied to the speaker 24 via the amplifier 22.

A microphone 26 for inputting a singer's song is connected to the amplifier 22. This microphone 26
The input singing voice is mixed with the electronic music signal by the amplifier 22 and output to the speaker 24.

As a first process, the control device 10 reads out MIDI data constituting the musical sound data 12a and sends it to the MIDI interface board 18. MI
The DI interface board 18 identifies and processes sound information and various control information in the MIDI data received from the control device 10, and sends the processed information to the MIDI multi tone generator unit 20.

Further, as a second process, the control device 10 displays the lyrics data 14a and the background video data 14b stored in the image information storage means 14 on the monitor 28.

FIG. 2A is a diagram showing the structure of the lyrics data 14a for one song in the image information storage means 14. As shown in FIG. The lyrics data 14a includes a lyrics color data table 30 and lyrics data 32 for one screen. Normally, in the case of a karaoke apparatus, a method of displaying lyrics one by one in parts is often used, but the one screen is used to indicate one of these parts. The lyrics color data table 30 is an area in which colors used for displaying lyrics are registered. Lyric data 32 for one screen
Is composed of a block number 32a and block data 32b. Here, the block represents a group of lyrics displayed on the monitor 28. That is, block data 3
Since 2b is the number stored in the block number 32a,
There is a possibility that a plurality of block data 32b exist in the lyrics data 32 for one screen.

FIG. 2B shows the structure of the block data 32b. The block data 32b includes a block data size 34, a display position 36, color data 38, the number of characters 40, a character code 42, and ruby data 44.

Since the block data 32b is variable length data, a block data size 34 representing the size of the data is required. The display position 36 indicates the display start position of the lyrics as a relative position with the origin at the upper left of the screen.

The color data 38 includes a character color 38a, a contour color 3
8b, a character color replacement color 38c, and a contour color replacement color 38d. The character color 38a, the outline color 38b, the character color change color 38c, and the outline color change color 38d are a character display color, an outline display color, a character color change color, and an outline color change color, respectively. Which color in the lyrics color data table 30 is used is stored as a number.

In the lyrics color data table 30, numbers corresponding to a plurality of colors are registered. For example, 20
If the color is registered, the display color of the character described above,
As the display color of the outline, the color of the character after the color change, and the color of the outline after the color change, any color can be freely selected from these 20 colors. The display color can be different for each block, and another color can be registered in the lyrics color data table 30 for each song. Therefore, for example, in the duet song, the display color of the lyrics is changed for each part sung by men and women, the display color of the lyrics is changed according to the tune, and the display color of the lyrics is selected so as not to be confused with the background image. Lyric display is possible.

The number of characters 40 represents the number of character codes 42. For one character code 42, data of the character body and data of the outline exist in correspondence.

The ruby data 44 is provided when ruby is required. The ruby data 44 includes a ruby block number 44a and ruby block data 44b. Since there may be a plurality of ruby in one block, the number is stored in the ruby block number 44a. A group of ruby is called a ruby block. Ruby block data 44b
Is composed of a ruby display position 441, a ruby character number 442, and a ruby character code 443. Ruby display position 441
Represents the display start position of ruby as a relative position with the display position 36 as the origin. The number of ruby characters 442 is the ruby character code 4
43 represents the number. For the ruby character code 443, the data of the ruby character main body and the data of the outline exist in correspondence.

FIG. 3 is a diagram showing a state in which lyrics are displayed on the monitor 28. In this FIG.
a, 50b, 50c and a ruby block 52 are shown. Then, one ruby block 5 is provided in the block 50c.
There are two. Each block 50a, 50b,
The solid line indicating the outer periphery of 50c is drawn for explanation of the figure and is not actually displayed on the screen.

FIG. 4 is a diagram showing the structure of the musical tone data 12a and the lyrics display instruction data 12b in the performance information storage means 12. FIG. 4A shows MIDI data 60, FIG. 4B shows synchronization data 62 related to lyrics display, and FIG. 4C shows end data 64 indicating the end of the MIDI data 60 of a song. The MIDI data 60 and the end data 64 correspond to the musical sound data 12a,
Corresponds to the lyrics display instruction data 12b.

At the beginning of the MIDI data 60, the synchronization data 62, and the end data 64, data types 60a, 62a, and 6 for indicating the type of each data are provided.
4a is recorded.

The MIDI data 60 has a data type 60
Subsequent to a, timing data 60b for controlling the timing for reading each data is recorded, and thereafter, various sound data 60c are recorded.

As shown in FIG. 4B, the synchronous data 62
Has a lyrics display flag 62b. The lyrics display flag 62b has the following four types: 1. Display flag for displaying one screen of lyrics 2. an erase flag for erasing one screen of lyrics; 3. A color change start flag indicating the start of color change for each block of lyrics. There is a color changing speed flag that changes the speed of changing the color of the lyrics. The speed data 62c is recorded after the color change start flag and the color change speed flag. Synchronization data 62 is MID
It is stored as appropriate between the I data 60, and displays, deletes,
You are instructing to change colors.

The end data 64 is stored at the end of the MIDI data 60 for one music piece and indicates the end of the music piece. By reading this data, the music reproduction operation ends.

Here, the synchronization data 62 will be described in detail. Regarding the embedding of the synchronization data 62 into the MIDI data 60, various measures have been taken to make the display, deletion and color change of the lyrics as smooth and easy to sing as possible.

First, the display flag and the color change start flag are embedded in the MIDI data 60 so that the time interval from the start of the lyrics display to the start of the color change is from 0.7 seconds to 2.5 seconds. I have. Similarly, the time interval from the end of the color change to the erasure of the lyrics is 0.1 seconds to 0.7 seconds, and the start of the color change of a certain character is 0.1 seconds from the time the character is actually sung. The embedding position of each flag is adjusted so as to be earlier.

Next, the speed data 62c specifies the number of dots to be changed in color per unit time. Speed data 6 where color change occurs slowly
2c has a low value, and the speed data 62c has a high value at a place where the color change occurs quickly. Speed data 62
c can be set up to two data for one character display. Further, a threshold value of the change amount of the adjacent speed data 62c is provided in order to make the unnaturalness of the rapid change of the color change speed unnoticeable.

By setting the synchronization data 62 as described above, the display, deletion, and color change of the lyrics are performed in a manner that is well matched to the timing of the utterance of the lyrics and is performed smoothly. is there.

As described with reference to FIG. 1, the control device 10 performs a plurality of processes such as music reproduction, lyrics display, and background image display in parallel. Of these, the music reproduction process is called a performance task, and the lyrics display process is called a display task, and the following description will proceed.

FIG. 5 shows the relationship between the performance task and the display task. The following four values are exchanged between the performance task and the display task: a block counter 70, a dot counter 72, a display instruction area 74, and an erasure instruction area 76. The exchange of data between the performance task and the display task will be described with reference to the flowcharts shown in FIGS.

The operation of the performance task will now be described with reference to the flowchart shown in FIG.

First, the MIDI interface board 1
When an interrupt is applied to the control device 10 from step 8, the performance task reads the musical sound data 12a from the performance information storage means 12 (S1). That is, one piece of the musical tone data 12a composed of each data as shown in FIG. 4 is read.

As a result of referring to the data type, if the read musical tone data 12a is the data type 60a indicating that it is the MIDI data 60 (S2; Y), the performance task sends the MIDI interface board 18 the timing data 60b and the timing data 60b. Each data of the sound data 60c is transmitted. The transmitted data is further sent to the MIDI multi-sound source unit 20 to reproduce a musical sound. Then, after a lapse of time specified by the timing data 60b, the control device 10 is interrupted, and the next tone data 12a is read.

If the read tone data 12a is not the MIDI data 60 (S2; N), it is determined whether or not it is the synchronous data 62 (S3). As a result of referring to the data type, if the read musical sound data 12a is the data type 62a indicating that it is the synchronous data 62 (S3; Y), the content of the lyrics display flag 62b is determined. When the lyrics display flag 62b is a display flag (S
7; Y), the display instruction area 74 is set. Similarly, when the flag is the erase flag (S8; Y), the erase instruction area 7
6 is set. When the lyrics display flag 62b is a color change start flag (S9; Y), the performance task increases the value of the block counter 70 by 1 (S13), resets the dot counter 72 (S14), and reads the speed data 62c (S13). S15) The addition value of the dot counter 72 for each unit time is calculated (S16), and the dot counter 72 is added for every fixed time (S17). In this way, the dot counter 72 stores the number of dots that should be changed by the current time. When the lyrics display flag 62b is a color change speed flag (S10;
Y), the processes from S15 to S17 are performed.

In S3, if the read musical sound information is not the synchronous data 62 (S3; N), it is determined whether the read musical sound information is the end data 64 (S4). As a result of referring to the data type, if the read musical sound data 12a is the data type 64a indicating the end data 64 (S4; Y), the performance task performs a reproduction stop operation for ending the performance (S5).

Hereinafter, the operation of the display task will be described with reference to the flowchart shown in FIG.

First, when the control device 10 starts the processing of the display task, the display task checks the display instruction area 74. When the display instruction area 74 is set (S21; Y), the display task displays one screen of lyrics (S22), and resets the display instruction area 74 (S2).
3). In the display instruction area 74, the setting by the performance task and the reset by the display task are repeated. Subsequently, the display task sets the color change block position, which is a value indicating the position where the color change is currently being performed, to 1 (S24).

Next, the display task is executed by the block counter 70.
Is read (S25). If the value of the block counter 70 is smaller than 1 (S26; smaller than 1), it means that it is not time to change the color of the block.
The display task waits until the block counter 70 becomes 1.

If the value of the block counter 70 is 1 (S26; 1), the display task reads the value of the dot counter 72 to change the color of the block (S27), and changes the color of the block to the position of the value. Execute (S28).
That is, the display colors of the character and the outline are respectively changed to the character color change color 3
8c, the color is changed to the outline color replacement color 38d. Dot counter 7
When the value of 2 becomes equal to the number of dots of the block (the number corresponding to the number of characters 40), that is, when the color change has been performed until the end of the block (S29; Y), the display task subtracts 1 from the block counter 70. (S30), 1 is added to the color change block position (S31), and the block for which color change is performed is moved to the next. If the color change has not been performed until the end of the block (S29; N), the display task reads the value of the dot counter 72 again and repeats the operation of changing the color. In this way, the color of the lyrics changes one after another up to the value of the dot counter 72, and a smooth color change is realized.

When the value of the block counter 70 is larger than 1 (S26; larger than 1), the following state is obtained. In the block counter 70, the addition of 1 by the performance task (see S13) and the subtraction of 1 by the display task (see S30) are alternately repeated, so that the determination in S26 is normally made. It becomes 1. However, since the control device 10 performs a plurality of processes in parallel as described above, the processing status of the display task may be delayed from the display instruction by the performance task. However, this is a time that humans are not aware of. If the performance task has already instructed the start of changing the color of the next block, but the display task has not completed the change of the color of the current block, the addition of the block counter 70 occurs twice. And its value exceeds one.

In such a case, the display task eliminates the display delay by performing the following processing.
First, the block which is currently changing the color is changed to the end (S34), 1 is subtracted from the block counter 70 (S35), and 1 is added to the color changing block position to change the color of the next block (S34). S36). After performing the above processing, the determination in S26 is performed again, and the color change is continued. The value of the dot counter 72 is reset each time the color change of the block is started by the performance task, and is added (see S14 to S17). pointing.

By comparing the color change block position with the number of blocks 32a of the lyrics data 32 for one screen, it is determined that the color change of all the blocks of the lyrics in one screen has been completed (S32; Y). ), The display task shifts to the process of deleting lyrics. Wait until the erasure instruction area 76 is set (S33; N), and when it is set (S34; Y),
The lyrics are deleted (S37), and the deletion instruction area 76 is reset (S38). In the erasure instruction area 76, the setting by the performance task and the reset by the display task are repeated.

Next, the display task determines whether or not the next lyrics data exists, and if there is the next lyrics (S39; Y), ST
Returning to ART, the same processing is repeated. If there is no next lyrics (S39; N), the display of the lyrics ends.

In the present embodiment, a plurality of processes are performed by one control device 10. However, it is also possible to allocate a separate control device for each process and synchronize the control devices. .
