Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lyrics display method and a lyrics display device used in a karaoke apparatus and the like, and a recording medium recording a lyrics display program.

[0002]

2. Description of the Related Art In a lyrics display device used in a karaoke device or the like, lyrics are displayed on a display according to the lyrics data recorded in a recording medium.
The lyrics data is stored in units of a predetermined phrase, and when the lyrics data is displayed, the lyrics data displayed at the delimiter position of the predetermined phrase is displayed with a line break. The number of characters displayed in one line at this time is the number of characters that can be displayed in one line on the display of the karaoke device used.

Then, when it is attempted to display the lyrics data created for a karaoke device having a large screen such as a CRT on a karaoke device having a small display such as an LCD display, the lyrics data for one phrase is displayed. Sometimes it couldn't be displayed on one line of the device, and the lyrics data sometimes went off the screen. To solve this, let the lyrics data include line feed data and sub-line feed data,
The number of characters that can be displayed on one line of the display device is compared with the number of characters up to the line feed code in the lyrics data. If the number of characters up to the line feed code is within the number of characters that can be displayed on one line of the display device, the line feed Display of lyrics data up to chord 1
If the number of characters up to the line feed code exceeds the number of characters that can be displayed on one line of the display device, the line feed is performed at the position of the sub-line feed code, and the lyrics data in two lines as a whole is displayed on the display device. It has been proposed by the present applicant (Japanese Patent Application No. 7-302025) to display the above-mentioned information.

[0004]

However, by comparing the number of characters that can be displayed in one line of the above-mentioned display device with the number of characters up to the line feed code in the lyrics data, whether or not to make a line feed at the sub-line feed code position is determined. In the method of determining, even if the font of the lyrics data is a proportional font in which the vertical and horizontal display dots are different depending on the character and can be displayed in one line, the sub line feed code is used. There is a problem that unnecessary line breaks may occur. That is, even if the number of characters up to the line feed code exceeds the number of characters that can be displayed on one line, it may be possible to display on one line if many characters with a small number of display dots are included in the characters. Since it is determined by the number of characters whether or not it can be displayed on one line, even if it can be displayed on one line, the line is always broken at the sub-line feed code position.

Since the sub-line feed code is frequently used as described above, the lyrics data for one page intended to be displayed on one screen is spread over a plurality of screens, that is, a plurality of pages. There is a problem that the possibility of being displayed increases and it becomes difficult to grasp the connection of the lyrics of karaoke.
Therefore, the present invention, when reading the lyrics data including the line feed code and the sub-line feed code and displaying the lyrics data,

The types of the external storage device 5 include a hard disk drive (HDD), a floppy (registered trademark) disk drive (FDD), and a CD-RO.
There are M drive, MO drive, etc.

A MIDI interface 6 receives a MIDI event and outputs a MIDI event generated in the musical tone generator, or LA.
It is a communication interface connected to a communication network such as N (Local Area Network), the Internet, or a telephone line. Reference numeral 7 is a keyboard for playing music that outputs MIDI data, and is connected to the bus 15 via the detection circuit 8, but it is not always necessary. Reference numeral 9 is a key switch for a so-called personal computer including keys such as letters, kana, numbers, symbols, a line feed key, a page break key, etc., or a panel switch for setting tone generation, and 10 is a switch operated. It is a detection circuit for detecting.

Further, reference numeral 11 denotes a display device (monitor) for displaying lyrics data and the like together with a background image, which is a video RA.
M (VRAM) 11-1 and lyrics display buffer (Buf
f) 11-2 and. Reference numeral 12 is a tone generator circuit that generates a tone signal based on the MIDI performance data stored in the RAM 3, 13 is an effect circuit that adds an effect such as reverb or vibrato to the tone signal passed from the tone generator circuit 1,
Reference numeral 4 denotes a sound system that amplifies the musical tone signal output from the effect circuit 13 to which the effect is added and emits the sound. The above configuration is equivalent to that of a computer such as a personal computer and a workstation, and the lyrics display method according to the present invention can be executed on them.

The operation of the musical tone generating apparatus thus constructed according to the lyrics display method of the present invention will be described with reference to FIGS. 2 is a diagram showing details of the character dot number table stored in the ROM 2, and FIG. 3 is a first example and a second example of input character data which is lyrics data displayed on the display device 11. 5 is a diagram showing a display mode of a first example of input character data, and FIG.
FIG. 6 is a diagram showing a display example of a second example of input character data.

Explaining an example in which karaoke is performed in the musical sound generating device, the performance data, the lyrics data, and the background video signal read through the external storage device 5 and the interface 6 are once stored in the RAM 3 to become a sounding time. The performance data read from the RAM 3 is read out from the RAM 3
2 to generate musical tone waveform data. Also, the lyrics data corresponds to the performance data in the external storage device 5 or R.
It is read from AM3, subjected to lyrics display processing, and then sent to the display device 11 for display. At the same time, the background image signal is also sent to the display device 11, and the lyrics data is superimposed on the background image signal and displayed on the display device 11. This allows the user to enjoy the background image displayed on the display device 11 by using a microphone (not shown) and sing along with the lyrics that are wiped as the performance progresses.

In the lyrics display processing at this time, the display device 11
The lyrics data created with the intention of displaying in one line so that it can be easily sung according to the lyrics displayed in is processed so that it can be displayed in one line as much as possible. It has been processed to be displayed. Specifically, the number of display dots for one line of the lyrics data in the proportional font is calculated and compared with the number of display dots for one line on the display device 11, and the display dot for one line on the display device 11 is calculated. When the number is larger, it is displayed on one line without using the sub-line feed code included in the lyrics data. In addition, when the sub-line feed code is unavoidably used, the number of lines for one page may increase and exceed the number of lines displayed on one page.
An auxiliary line is provided as the number of lines that can be displayed on one page, and when the number of lines displayed on a predetermined page is exceeded, the line is displayed using the auxiliary line so that it is displayed over multiple pages. I try to prevent that.

Therefore, the ROM 2 stores the character dot number table of the proportional font shown in FIG. As shown in FIG. 2 (a), the character dot number table is used to display the vertical and horizontal display dots of other letters such as lowercase letters a to z, uppercase letters AZ, numbers 1 to 0, symbols, etc. It is a table consisting of. For example, the details of the dot number table for lowercase English letters are shown in Fig. 2 (b). In the case of the alphabet "a", when the display is enlarged, it is 10 dots horizontally and 10 dots vertically. Is 8 dots horizontally and 8 dots vertically, and when the display is small, it is 6 dots horizontally and 6 dots vertically. Also, in the case of the letter "b", when the display is enlarged, it is 15 dots horizontally and 10 dots vertically, and when the display is standard, it is 1 horizontal.
The dots are 2 dots and 8 dots vertically, and when the display is small, it is 9 dots horizontally and 6 dots vertically. In this way, the number of horizontal dots and the number of vertical dots displayed according to the size of the display and the characters are different.

Although the number of display dots of Japanese characters is changed according to the size of the display, the number of display dots is fixed and does not change even if the characters are different.
For example, the standard number of display dots in Japanese is, for example, horizontal 14 dots, vertical 16 dots, large display dot is horizontal 16 dots, vertical 16 dots, and small display dot is horizontal 1
There are 2 dots and 16 dots vertically.

Therefore, in FIG. The lyrics display method of the present invention will be described in detail by taking as an example the case where the input character data 1 in the proportional font shown in FIG. The input character data 1 shown in is the character data for one page, "|" inserted between the characters indicates the delimiter of the character (lyric) event, "#" is the page break code, and ""%" Is a sub-line feed code. That is, the input character data 1 is intended to be displayed in one line, and the displayed character (lyric) is “aiueo fghij”. When the lyrics are displayed by the conventional character display method described above, that is, the method of determining whether to use the sub-line feed code based on the number of characters in one line, the sub-line feed code is used as shown in FIG. Displayed in a row. As a condition in this case, only 9 characters can be displayed in one line on the display device 11, and one line of the display device 11 at this time has a dot number of 144 dots (9 characters × 16 dots). ) Is said.

By the way, in the display method of the present invention, the number of dots of the font of the character data of one line is calculated. In the case of input character data 1, the number of dots required to display "fghij" may be smaller than the number of dots displayed in Japanese (for example, 16 dots) as in the table shown in FIG. The total number of displayed dots of the input character data 1 is within the number of dots of one line on the display device 11.
Therefore, according to the display method of the present invention, "aiueo fghij" can be displayed in one line as shown in FIG. In addition, "aiueo fghi" shown in FIG.
The two lines shown above "j" are auxiliary lines provided in the present invention, in which case nothing is displayed in the auxiliary line.

Next, referring to FIG. The case where the input character data 2 in which the large and small characters shown in FIG. B. of FIG. Input character data 2 shown in is character data for one page, "/" inserted between the characters indicates a line feed code, "|" indicates a character (lyric) event delimiter, and "#" indicates Is a page break code,
"%" Is a sub-line feed code. In other words, the input character data 1 is intended to be displayed in two lines, and the displayed characters (lyrics) are "aiueyayuyoue", which consists of large and small characters in the first line. The second line is "Kakikushi Koshishi Sesso", which is composed only of large characters.

When the lyrics are displayed under the same conditions as in the case of the input character data 1 in the conventional character display method described above,
As shown in FIG. 5A, the sub-line feed code is used, and the entire line is displayed in the display form of 4 lines. In the display device 11, the display line of the conventional character display method is 2
Since there are up to two lines, each line will be displayed over two pages. Then, in the lyrics display method of the present invention, when the number of display dots of the character data in the first line of "Aiu-e-a-u-yo-e" is calculated, the characters "u" and "-ayu-e-o" are Since it is small, the number of dots required for the display is small, so that the total display dot number of the input character data 2 is within the dot number of one line in the display device 11. Therefore, according to the display method of the present invention, as shown in FIG.
As shown in, it becomes possible to display "Aiu-e-a-u-you-oo" on one line.

[0028] In addition, the second line "Kakikushi Koshishi Sesso"
When the number of dots required to display is calculated to be 160 dots, which exceeds 144 dots, the sub-line feed code "%" inserted after "ko" is used, and "kakikuke" and "sashisuseso" are used. Will be displayed in two lines. At this time, since the input character data for one page is displayed in three lines that exceed the predetermined display line number of the display device 11, which is two, the auxiliary line is used. One line of "Aiu-e-a-u-you-oo" will be displayed on the auxiliary line. In the example shown in FIGS. 4 and 5, the auxiliary line is provided above the line where the lyrics data is originally displayed, but the present invention is not limited to this, and the originally displayed line is at the top and the auxiliary line is provided. You may make it provide in the lower part.

In the display method of the present invention, as described above, the lyrics data created with the intention of displaying in one line can be displayed in one line as much as possible.
The display device 11 without the lyrics data of one page being spread over a plurality of pages
Will be able to display. The display device 1
1, the lyrics data read from the external storage device 5 or the RAM 3 is subjected to the above-mentioned lyrics display processing by the CPU 1 executing the lyrics display program stored in the ROM 2, and the lyrics display buffer 11- Written to 2. Then, it is superposed on the digital background video signal and written in the VRAM 11-1.
After being read from the AM 11-1 at a predetermined line cycle and converted into an analog signal, it is displayed on the screen.

Next, the lyrics display method of the present invention will be described with reference to the flowcharts of the lyrics display processing shown in FIGS. However, in this flowchart, the number of lines that can be displayed on one screen is set to 4 lines including two auxiliary lines, and the number of dots that can be displayed on one line of the display device 11 is 16 dots vertically and 144 dots horizontally.
It has dots. In addition, the input lyrics data includes a line feed code, a page feed code, and a sub-line feed code, and display time data is given for each character, and the page break is made within two lines. There are three types of sizes: large, standard, and small. Here, when the lyrics display process is activated, one line of lyrics data up to a line feed code is read from the internal storage device such as the floppy disk (FD) or the RAM 3 set in the external storage device 5 in step S10. . Next, 1 read in step S11
The number of dots for the line is calculated. At this time, for Japanese, the number of display dots when the display is standard is 14 (horizontal) ×
16 (vertical) dots, the number of display dots when the display is large is calculated as 16 × 16 dots, and the number of display dots when the display is small is calculated as 12 × 16 dots, and alphabets and numbers are assumed to be proportional fonts. Therefore, the calculation is performed by referring to the character dot number table stored in the ROM 2 shown in FIG.

Then, in step S12, it is determined whether or not the sub-line feed code is included. If the sub-line feed code is included in the input lyrics data, the process proceeds to step S14 and the measurement is performed in step S11. It is determined whether or not the number of dots is within 144. At this time, if the number of dots exceeds 144 dots, the process branches to step S16 to use the sub-line feed code, and the process proceeds to step S17. If the number of dots is less than 144 dots, the process proceeds to step S1.
Proceed to 7. As a result, if the total number of dots of the lyrics data for one line is within 144 dots, the lyrics data for one line will be displayed on one line as shown in FIG. 4 (b) or FIG. 5 (b). When the total number of dots of the lyrics data for one line exceeds 144 dots, the display mode is such that a line feed is made at the position of the sub-line feed code.

When it is determined in step S12 that the sub-line feed code is not included, the process proceeds to step S13, and it is determined whether or not the number of dots measured in step S11 is within 144 dots. At this time, when the number of dots exceeds 144, the process branches to step S15 and 144
Automatic line feed processing is performed at the head of the character that does not fit in the dots, and the process proceeds to step S17. If the number of dots is less than 144 dots, the process proceeds directly to step S17. The beginning of the character on which the automatic line feed process is performed may be replaced with the beginning of a phrase or an English word.

In step S17, a process using the line feed code is performed, and in step S18, the lyrics data processed by the above processes is written in the lyrics display buffer 11-2. The processing from step S11 to step S17 is the line feed determination work processing using the number of dots. Then, in step S19, it is further determined whether the lyrics display buffer 11-2 can be written. Here, if the lyrics display buffer 11-2 has room and it is determined to be YES, the process returns to step S10, the lyrics data of the next line is read, and the read lyrics data is added to the steps S11 to S11. The above-described processing of S18 is performed. Thus, the processing of steps S10 to S19 is performed by the lyrics display buffer 11-2.
Is repeatedly executed until there is no room in the storage area.

When the storage area of the lyrics display buffer 11-2 is full and it is determined to be NO in step S19, it is determined in step S21 shown in FIG. 7 whether or not the lyrics display timing has been reached. . The lyrics display timing is based on display time data given for each character, and becomes the next lyrics display timing when the display time of the previous page ends, for example. This step S
21 is cyclically executed until the lyrics display timing is reached. When the lyrics display timing is reached, step S22 follows and the lyrics data for one page up to the page feed code is read from the lyrics display buffer 11-2. Next, in step S23, it is determined whether the number of lines to be displayed is five or more and whether the display extends over a plurality of pages. If it is not determined that the display extends over a plurality of pages, the process branches to step S25 and is read. Further, the display time is obtained from the sum of the time data of each lyrics data. If it is determined in step S23 that the display spans a plurality of pages, the process proceeds to step S24, and the display time is obtained by the sum of the lyrics data of the first page for the first four lines. And a new page is provided,
The display time of the new page is obtained from the total sum of the lyrics data of the 5th and subsequent lines.

Subsequently, the lyrics data is transferred to the VRAM 11-1 in step S26, and 1 is transferred in step S27.
Pages of lyrics will be displayed on the screen. At this time,
When a new page is provided, the lyrics data of the new page will be displayed after the display time of the first page is finished. Then, when the display time of the displayed page ends, the lyrics data transferred to the VRAM 11-1 in step S28 is deleted from the lyrics display buffer 11-2. Then, in step S29, it is determined whether or not the lyrics data remains in the floppy disk (FD) set in the external storage device 5 or the internal storage device such as the RAM 3 or the like. Then, the process returns to step S10. Then, the processes of steps S10 to S29 described above are repeatedly executed. If all the lyrics data are read out from the FD, the RAM 3, etc., the determination is NO and the process branches to step S30, where the lyrics data not displayed in the lyrics display buffer 11-2 is found. It is determined whether or not it remains.

If the lyrics data not displayed in the lyrics display buffer 11-2 remains, the process returns to step S21 and steps S21 to S2.
The process 8 is executed and the lyrics data is displayed on the screen. This processing is performed by the lyrics display buffer 11-
When the lyrics data to be displayed in the lyrics display buffer 11-2 is exhausted, the determination is NO in step S30 and the lyrics display process is ended. At this time, the performance based on the performance data is almost finished.

In the above-mentioned flowchart, the line feed judgment work process based on the number of dots is performed in the lyrics display buffer 11.
Although it is executed before writing to the -2, it is also possible to execute the line feed determination work process based on the number of dots after writing the lyrics data to the lyrics display buffer 11-2. Also, the lyrics data is FD in the form of being included in the performance data.
It may be stored in the computer or may be fetched from the interface 6. Furthermore, in the character dot number table, the character size is divided into standard, large, and small as shown in FIG. 2, but the method of dividing the size is not limited to this, and may be finely divided by the number of dots. Further, the size may be one. Furthermore, in the character dot number table, lowercase letters, uppercase letters, numbers, etc. are classified, but this classification may be performed on a word-by-word basis or may be grouped together without classification.

Furthermore, in the above description, the alphabetical characters of the proportional font and the like are used, but the line break determination processing using the alphabetical characters and the like of the monospaced font may be executed. Furthermore, the lyrics display processing is performed by reading the lyrics data for each line feed code, but the lyrics data until multiple line feed codes at one time or multiple page break codes are read is displayed. It may be read. Furthermore, although the lyrics data is written to the lyrics display buffer 11-2 until the capacity of the storage medium is filled, the lyrics data is written when the lyrics data of a predetermined number of lines or pages is written. May be terminated. At this time, the lyrics display buffer 11-2 may be used as a variable-capacity storage medium by writing only the specific page number or the specific line number. Furthermore, in the embodiment, the explanation is given regarding the horizontal lyrics display, but when the lyrics display is vertical writing, the same control as described above can be performed by determining the number of vertical dots. It should be noted that the present invention can also be used for display of simple lyrics without time data and character display of advertisements and the like.

The musical tone generating apparatus shown in FIG. 1 for carrying out the lyrics display method of the present invention described above is provided with the lyrics display apparatus of the present invention. You may make it implement | achieve as a form of a program. At this time, the lyrics display program can be stored in a storage medium such as a magnetic disk, an optical disk, or a semiconductor memory, and supplied to the computer.
Alternatively, the lyrics display program may be supplied from the interface 6 using a communication means such as a network. Further, the present invention can be naturally applied to a device dedicated to karaoke, and can also be applied to an electronic piano. Furthermore, the present invention may be applied to a system in which a tone generator device, an automatic performance device, and the like are separately prepared or are connected to each other through a network.

A hard disk drive (HDD) is provided as one of the external storage devices 5, and an HD
A lyrics display program for executing the above-mentioned lyrics display method of the present invention on a computer is stored in D,
The lyrics display processing described above may be executed by loading this program into the RAM 3. By doing so, it becomes possible to easily add programs and upgrade versions. Further, instead of the HDD, a CD-ROM or a magneto-optical disk (MO) device having the same function may be provided as one of the external storage devices 5.

[0041]

As described above, the present invention compares the number of dots that can be displayed in one line of the display device with the number of dots required to display the characters up to the line feed code in the lyrics data. Whether or not to break a line at the sub-line feed code position is determined. Therefore, the lyrics data font is
Even if it is a proportional font in which the number of display dots differs depending on the character, it is possible to display as much as possible on one line of the display section without using a sub-line feed code Become. Also, if the displayed lyrics data is displayed with line breaks at the sub-line feed code position, if the number of lines displayed due to line breaks exceeds the specified number of lines, the auxiliary line in the display section is used. Since the lyrics data of one page intended to be displayed on one screen is displayed over a plurality of pages as much as possible, it is easy to grasp the connection of the lyrics of karaoke. The effect can be achieved.
