DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A karaoke apparatus according to an embodiment of the present invention will be described with reference to the drawings. This karaoke apparatus is a sound source karaoke apparatus that reads out music data and supplies it to a sound source to form a musical sound of a karaoke performance. This song data contains guide melody data, which is read out in parallel with the karaoke performance, and the singing voice signal input from the microphone is compared with this guide melody data to score the singing accuracy. Has functions. Further, the karaoke apparatus has a game function for executing a scoring game in which the scoring function is turned into a game. The scoring game is executed by scoring game script data that is ICM script data. The ICM script data is script data for executing functions other than karaoke performance on the karaoke apparatus.

Music data for performing karaoke performance is also IC
The M script data is also identified by the song number. The music data is identified by a 6-digit music number consisting of a 4-digit singer number and a 2-digit singer-specific music number. ICM script data is similarly identified by a six-digit number. The scoring game script data contains 8000-01 and 8000-
A song number of 02 is assigned. Therefore, the karaoke user can select a scoring game by the same operation as selecting a karaoke tune with a remote control device or the like, and instruct the start / end.

In addition to a music number corresponding to the music data on a one-to-one basis, a random music selection number which is a music number corresponding to a plurality of music data is provided. The random song selection numbers include a genre designated song number and a singer designated song number. Genre designation song number is 8000-11,8000
-12,8000-13,8000-14, and 8000-11,8000-12,8000-1
3,8000-14 song numbers are best 50,
It supports pops, enka, and all genres. When the song number is registered and reserved, the karaoke apparatus randomly selects one song of the corresponding genre with reference to the index file and plays the song. Since the selection of the music is performed immediately before the performance, the user can have a game characteristic that he or she does not know which music is played until immediately before the performance.

The singer-specified song number is the singer number +00
Song number. That is, a song number corresponding to song data on a one-to-one basis is assigned a song number by singer from 01 to 99 next to the singer number, and a song number by singer of 00 is all songs of the singer number (singer). Is assigned as the song number corresponding to. When a song number of singer number +00 is designated, the karaoke apparatus randomly selects and plays one song from the songs of the singer of this singer number. Some singers have registered over 100 karaoke songs as song data, and these singers are assigned two singer numbers. Such a singer number duplicatively assigned to the same singer is registered in a double number table, and when a song number of singer number +00 is designated, there is a duplicate singer number for the same singer from the double number table. Or search. If there is a duplicate singer number, one song is selected from the songs of both singer numbers. Since the selection of one tune by the singer number +00 tune number is also performed immediately before the performance in the same manner as the genre-specified tune number, the user can have a game characteristic that he or she does not know which tune will be played until immediately before the performance. it can.

When the user inputs the music number from the remote control device, the karaoke apparatus registers the music number in a reservation list, and plays the music in order from the previously registered music. However,
8000-0 which is the number of the scoring game script data
If 1 or 8000-02 is input, it is automatically treated as a priority interrupt reservation, and this number is registered at the top of the reservation list. When the music being played at that time ends, this is executed prior to another reserved music.

When the ICM script data of either 8000-01 or 8000-02 is executed, the screen shown in FIG. 16 is first displayed. The user can select one of the three games of the karaoke audition game, the red and white singing battle game, and the color lympics game on this screen. After reading the script track and image data corresponding to the game selected by the user, the karaoke apparatus returns to the karaoke performance operation similar to the normal karaoke performance mode. The above three types of scoring games progress by scoring the karaoke singing of the user by the karaoke performance. The song number 8000-01 is script data for executing a normal scoring game. 8000-02 executes the exact same game as the 8000-01 scoring game, but executes the game in the "entertainment mode" in which the score is displayed higher than usual.

The karaoke audition game is a game in which the audition of a singer is imitated. After the karaoke singing is completed, three judges judge the score based on the result of the singing. The scoring of the karaoke song is performed for three elements, pitch, volume, and rhythm, and the three judges display the scores of the pitch, volume, and rhythm out of 100 points (see FIG. 17B).
In addition, the total score, which is the average of these three scores, is also displayed. If the score is 95 or more, a blessing screen of "Million Seller" is displayed. Further, in this game, the skill of the singing and the advice words are displayed in real time during the karaoke performance. As shown in FIG. 17A, the face of the chairman of the judging committee and the advice wording as his / her words are displayed at the upper right of the screen. The judge's facial expression changes to a smile or a frown according to the real-time score (phrase point described later) at that time, and the score at that time is displayed, and where to correct the above three elements is determined. It is displayed as advice text.

The red and white singing battle game is a game in which the singers of the red and white singer alternately sing and sum up the scores to compete for the size of the total score. When the game starts, the music already reserved and the music to be reserved are alternately sorted into the red group and the white group, and the singing scores of the music are accumulated in the red group score counter and the white group score counter, respectively. These red group score counter and white group score counter are set in the RAM of the karaoke apparatus. The karaoke apparatus displays a list of song names reserved after this song as a “reservation queue” immediately before starting to play the song. In this red-and-white song battle game, the song name of the song By displaying a red microphone at the beginning and a white microphone at the beginning of the song name sung by the white group, it is possible to immediately recognize which song is the red group and which is the white group. Also, on the title screen at the start of the karaoke performance, as shown in FIG. 18 (A), illustrations and words such as "Let's go white!" I try not to make a mistake when singing. In addition, during the karaoke performance, an animation in which the face of the singer's captain moves in accordance with the rhythm of the song is displayed at the upper right of the screen to support the singer. As described above, in the red-and-white singing battle game, the display is devised so that it is easy to understand which of the red and white singing turn is to be sung.

In the red and white song battle game,
When the White Singers sing three by three, an interim announcement of the total score is made at that point. This interim announcement is repeated every time six people sing. The game is again 8000-0 by the user
1 or 8000-02 is reserved, scoring game script data is called, and the game ends when the game end is selected. When the end of the game is selected, the karaoke apparatus displays a selection screen as to whether the game is to be ended immediately or there is a bird (the last person to sing). By terminating the game and adding the score of the last two singers, which are birds, to three times the score of the previous singers, a so-called "one-shot reversal" is made possible.

The Karalympics game is a sport-like game in which the singer changes the tempo or key (key) of the karaoke performance at random and competes for singing following it. The tempo changes smoothly over several seconds, and the keys change from the current key to the new key at once, so that the karaoke performance does not become too natural. The amount of key change is an arbitrary magnitude in semitone units. The keys are moved up and down based on the original keys. That is, when changing from the original key to another key, the key is always returned to the original key and then changed to the next key. When the key and the tempo are changed at the same timing, the tempo change is started when the key changes.

In the Karalympics game, during a karaoke performance, an animation in which a competitor is running is displayed on the upper right of the screen as shown in FIGS. 19 (A) and 19 (B). This animation is controlled so that the running speed changes according to the change in tempo, and jumps and squats according to the up and down of the key. By changing the running speed to the start timing of the tempo change, and making the jump or squatting one second before the up and down change of the key,
The tempo and key changes are announced in advance to make it easier for the singer to follow.

The panel switch 15 includes a numeric keypad, a key change switch, and a tempo change switch similar to those of the remote controller 8 for inputting a music number.

The tone generator 18 forms a tone signal based on tone track data of the music data. The tone track has a plurality of tracks, and the tone generator 18 simultaneously forms tone signals of a plurality of parts based on the data. The audio data processing unit 19 forms an audio signal having a specified length and a specified pitch based on audio data included in the music data. The sound data is a signal waveform that is difficult to form electronically, such as a human voice such as a back chorus, and is stored as it is as a PCM signal. The tone signal formed by the sound source device 18 and the sound signal reproduced by the sound data processing unit 19 are input to the control amplifier 2. The control amplifier 2 has two microphones 7a, 7
b is connected, and the singing voice signal of the karaoke singer is input. The control amplifier 2 applies a predetermined effect such as an echo to each of these audio signals, amplifies them, and outputs them to the speaker 5.

The audio signal processing device 3 inputs guide melody data from the CPU 10 during a karaoke performance and inputs a singing audio signal input from the microphone 7 from the control amplifier 2. The guide melody data is read from the music data in parallel with the karaoke performance. The guide melody data is MIDI data, but the CPU
10 converts the MIDI event data into frequency data and volume data, and inputs the data to the audio signal processing device 3. The audio signal processing device 3 calculates singing frequency data and singing volume data from the singing voice signal, compares the singing frequency data and the singing volume data with the frequency data and volume data of the guide melody, and calculates difference data that is the difference therebetween. The calculation of the difference data is executed every 150 ms. The calculated difference data is input to the CPU 10. The CPU 10 integrates the difference data input from the audio signal processing device 3, and scores a karaoke singing based on the integrated value. This scoring operation will be described later in detail.

The audio signal processing device 3 is originally a device that detects the frequency of a singing voice signal and converts the frequency to generate a singing voice signal of the harmonic melody part. That is, when a karaoke song is being played in the hamori mode, the data of the harmony melody part is input from the CPU 10 and the frequency of the singing voice signal input from the microphone 7 is converted in accordance with the data to thereby provide the harmony melody part. To generate a singing voice signal. The singing voice signal of the harmonic melody part thus formed is input to the control amplifier 2, amplified with the singing voice signal of the main melody, and output from the speaker 5.

The character display section 20 generates character patterns such as song titles and lyrics based on the input character data. The LD changer 4 as an external device reproduces a moving image as a background image based on the image selection data input from the CPU 10. The video selection data is determined based on genre data or the like written in the header of the music data. The display control unit 21 superimposes a character pattern such as lyrics input from the character display unit 20 on the background image input from the LD changer 4 in superimposition and displays the superimposed character pattern on the monitor 6. In the game mode, various characters and animations other than the background image and the lyrics are input to the display control unit 21 and displayed on the monitor 6.

The billing device 9 is a device for receiving coins such as 100 yen coins, and stores the number of coins inserted as credits. The karaoke apparatus main unit processes the pay service according to the credit balance of the charging apparatus 9. In this embodiment, the karaoke audition scoring function is charged.

FIG. 2 is a diagram showing a configuration of music data used in the karaoke apparatus. The music data includes a header, a musical sound track, a guide melody track, a lyrics track, a voice track, an effect track, and a voice data section. The header is a part in which data relating to the attribute of the music data is written, and data such as a music title, a genre, an announcement date, and a music performance time are written therein. Each track from the musical sound track to the effect track is described in a MIDI format including a plurality of event data and duration data indicating a time interval between the event data. The data from the lyrics track to the effect control track are not musical sound data, but these tracks are also described in MIDI format in order to unify the implementation and facilitate the work process.

The tone track is composed of a plurality of parts for driving the tone generator 18 to form a plurality of tone signals. In the guide melody track, data of the main melody of the karaoke song, that is, the melody to be sung by the singer is written. The lyrics track is a track that stores sequence data for displaying lyrics on the monitor 6. The event data of the lyrics track is composed of the character code of the lyrics and data indicating the display position thereof. The audio control track is a track for specifying the utterance timing of the audio data group stored in the audio data section. PCM data such as human voice is stored in the audio data section, and the event data of the audio control track specifies which audio data is reproduced at the event timing. In the effect control track, effect control data for controlling the control amplifier 2 is written. The control amplifier 2 applies a reverberation or other reverberation effect to the tone signal based on the effect control data.

In addition, I for executing a function such as a scoring game
The CM script data has substantially the same configuration as the music data, and includes a header in which data such as a script name and a release date of the ICM script data is written, a script data body, and a plurality of data used when executing the script. Image data and text data group. In the case of the scoring game script data, a script data track is set for each of the karaoke audition game, the red and white singing battle game, and the Karalympics game, and the image data for displaying the screens and animations shown in FIGS. Data and the like are written, and as text data, advice texts and the like displayed in the karaoke audition game are written.

Here, the audio signal processing device 3, the CPU
The ten scoring functions will be described. When the user inputs a song number of 8000-01 from the remote control device 8, ICM script data of the scoring game starts, and the operation of the karaoke device is set to the scoring game mode. Thereafter, the operation returns to the normal operation of playing the selected karaoke tune, and the scoring game operation is executed during this performance.

When singing along with the karaoke performance, the singing voice signal is input from the microphone 7, and the singing voice signal is input to the voice signal processing device 3 via the control amplifier 2. The audio signal processing device 3 analyzes the frequency and volume of the input singing voice signal, and generates singing frequency data and singing volume data. Then, these data are
Difference data is calculated by comparing the frequency data and the volume data of the guide melody input from U10. This comparison is performed every 150 ms. The calculated frequency difference data and volume difference data are returned to the CPU 10.

The CPU 10 integrates the difference data input every 150 ms. Also, rhythm difference data is calculated based on the difference between the rising timings of the singing volume data and the volume data of the guide melody, and this data is also integrated. Then, this integrated value is totaled for each phrase of the karaoke song, and a pitch point, a volume point, and a rhythm point are calculated. This point is calculated by subtracting the deduction point value based on the integrated value of the difference data from the full score. The points calculated for each phrase as described above are accumulated and stored. And at the end of the karaoke song,
The total music points are calculated by totalizing the accumulated points. The all music points are separately calculated for three elements of frequency (pitch), volume and rhythm.

The pitch, volume, rhythm phrase point, and all music points calculated by the above operation are used in the scoring game. Phrase points are used in scoring games.
In the scoring game, the expression of the animation of the chair of the judging committee is changed based on the phrase points, and the advice wording on the points to be corrected is displayed as a speech balloon of this face (a field for writing lines in manga). When the phrase points are high, the judge is smiling, and when the points are low, the judge is frowning. In addition, since the user sings with a low voice, especially when the volume point is low, an advice word such as "louder voice" is displayed. After the karaoke song ends, the scores displayed by the three judges are the display scores calculated based on all the song points of the pitch, volume, and rhythm, respectively. FIG. 17 (B)
In the example, the scores displayed by the three judges are (pitch, volume, rhythm) as (100, 0, 0), (0,
100, 0) and (0, 0, 100). That is, they are scores for the pitch, volume, and rhythm, respectively. In addition to this, for example, three judges are set in genres such as enka, pop, and orthodox schools, and scores calculated by weighting singing abilities suitable for singing songs of the genres, respectively. May be displayed. For example, for enka (60, 30, 10), for pop (20, 40,
40), weighting such as (40, 30, 30) in the case of the orthodox school can be considered.

FIGS. 3 to 15 and FIGS. 21 to 23 are flowcharts showing the operation of the karaoke apparatus. FIG. 3 is a flowchart showing the reservation registration processing operation. This operation is performed when a reservation of a music number is input from the remote controller 8 or the like. When a song number is input from the remote controller 8 or the like (s1), the song number is the number of scoring game script data for setting / releasing the scoring game mode, that is, 8000-01 or 8000-02.
It is determined whether it is a specific number such as (s2). If it is a specific number, this song number is registered at the head of a reservation list that stores the song numbers entered by reservation in the input order (s4). If it is any other normal music number, this music number is registered at the end of the reservation list (s3). Specific numbers include, in addition to the song numbers in the scoring game script data, ICM script data for reproducing the instruction manual of the karaoke apparatus.

FIGS. 4 to 7 are flowcharts showing the data read processing operation. In this operation, the music number is read from the reservation list, the music data or the ICM script data for the karaoke performance specified by the music number is read, and the data is sequentially executed. First, during karaoke performance (including execution of ICM script data)
Is determined (s10). If a karaoke performance is being performed, the process waits until the karaoke performance ends. When the karaoke performance ends, there is a reserved song,
Determine whether the song number is registered in the reservation list (s
11). If there is no reserved song, proceed to the CM screening operation (s
11). If there is a reserved song, the song number written at the top of the reserved list is read (s12), and the type of the song number is determined (s13). If the music number is a normal music number designating one music data, the process proceeds directly from s13 to s15. When the music number is a random music selection number of the genre-specified music number or the singer-specified music number, one music is randomly selected in accordance with the music number (s1).
4) Go to s15.

Here, the random music selection operation will be described with reference to FIG. FIG. 21A is a diagram illustrating the configuration of an index file. FIG. 7B is a diagram for explaining the configuration of the music number table. Both the index file and the song number table are stored in the hard disk storage device 17.

The index file is a file in which the types of all the music data stored in the hard disk storage device 17 are stored. A genre flag indicating the genre (whether it is an enka) of the music data, a BEST flag indicating whether the music data is within the top 50 of the number of requests, one month after being distributed, corresponding to the music number of each music data New score flag indicating whether the new score is within
That is, a scoring possible flag indicating whether or not a guide melody track is included, and a random exclusion flag indicating whether or not to be excluded from random music selection are set. If the genre flag is set, the song is an enka and the pops are resetting. The tune set by the BEST flag is the hit tune within the 50th rank. The song whose new score flag is set is a new song within one month from the release. A song set with the scoring flag is a song that includes a guide melody in the song data, can operate a scoring function, and can be used in a scoring game. This flag is provided because some song data distributed in the past does not include a guide melody. The songs set with the random exclusion flag are songs excluded from the random song selection based on the genre-designated song number. For example, a singer may not be able to sing at all when a special song such as a foreign language song is played in a random song, so a random exclusion flag is set for such a special song, and Exclude from However, in the case of the singer-specified song number, it is considered that the singer is conscious of the possibility that a special song such as a foreign language will be played because the singer is decided, so such a song is also random. Do not exclude from song selection.

The music number table of FIG. 21B is a table that stores the number of music numbers having each singer number. Since the song numbers are assigned in order from 01, by storing the final song number for each singer, it is possible to know how many songs are registered with that singer number. Also, some singers have registered more than 100 songs, and some singers are assigned two singer numbers to the same singer, so singer numbers linked for such singers are also stored. . That is, if more than 100 songs are registered and two singer numbers are assigned to the same singer, the other singer numbers assigned to the same singer are stored in each of these two singer numbers. In this way, even when a singer-specified song number of one singer number +00 is input, random song selection including songs included in other song numbers can be performed.

FIG. 9C is a flowchart showing a random music selection operation. When the random song selection number is read, it is first determined whether the random song selection number is a genre designated song number or a singer designated song number (s200). If it is a genre designated song number, the process proceeds to s201, and if it is a singer designated song number, the process proceeds to s205. In s201, the index file is searched, and the specified genre (pops, enka,
BEST 50, all songs), songs that are not excluded from random song selection are extracted as target songs. In s203, it is determined whether or not the grading game is currently being executed. If the grading game is being executed, the non-scorable music pieces whose gradeable flag is reset are excluded from the target (s203). Then, a random number is generated, and the random number is mapped according to the number of music pieces to obtain 1
A song is selected (s203). The music data of the selected music is read out in s19 and below. On the other hand, when the random music selection number is the singer-specified music number (s200),
The song number table is searched to read the number of songs of this singer number (s205), and it is determined whether or not this singer number has a link destination (s206). If there is a link destination, the column of the link destination singer number is searched to read out the number of songs, and is added to the read number of songs (s207). Then, a random number is generated, and the random number is mapped according to the number of music pieces to determine a music piece number of the selected music piece (s208). Thereafter, it is determined whether or not the current mode is the scoring game mode (s209). If the current mode is the scoring game mode, the index file is searched with the selected music number to determine whether or not the music of this music number can be graded (step S209). s210). If it is not in the grading game mode, or if the selected tune is a gradable tune, the operation returns to the operation of FIG. 4 with this tune number.
Returning to step 8, a random number is generated again, and the music is selected again.

In FIG. 4, if the music number read out at s13 is 8000-01 or 8000-02, the operation proceeds to s30 and below (FIGS. 6 and 7) for the game menu processing.

Here, the game menu processing operation will be described with reference to FIGS. In s30, first, the contents of the mode register mode are determined. mode is a register for storing the current operation mode. The mode register takes values from 0 to 4, where 0: normal karaoke performance mode, 1: karaoke audition game mode, 2: red and white singing battle game mode, 3: caralympics game mode, and 4: red and white singing battle game. Mode.

If the mode is 0 in s30, this indicates that the ICM script data has been selected to start the scoring game from the normal karaoke performance mode.
If the mode register is 1 to 4, it indicates that the ICM script data has been selected to end the scoring game, and the process proceeds to the game end operation of FIG.

At s31, a menu screen of the scoring game shown in FIG. 16 is displayed. The user presses the △ key or ▽ key of the remote controller 8 to move the cursor to a desired game position. When the △ key is turned on (s32), the karaoke apparatus moves the cursor on the screen one counterclockwise (s35). When the ▽ key is turned on (s33), the cursor on the screen is moved one clockwise (s36). When the start key is turned on (s34), the process proceeds to s37 and the following to set the game mode displayed at the position of the cursor at that time.

If the selected game is a karaoke audition game (s37), the mode register mode is set to 1 (s40), the menu screen is erased, and the screen returns to the normal karaoke performance screen to perform this operation. Is completed (s41). If the selected game is a red and white singing battle game (s38), the mode is set to 2 (s42), the red set flag for determining the singing group is set to 1 (s43), and up to the intermediate counting. C to count the number of songs
m is cleared (s44), the red group score counter for summing the red group scores, and the white group score counter for totaling the white group scores are cleared (s45), and the process proceeds to s41. In s41, the screen is returned to the normal karaoke performance screen, and the operation ends.
In addition, when the color Olympic game is selected (s
39), 3 is set in mode (s46), and s41
Proceed to. When "quit" is selected, no game is selected, and only the screen is erased (s
41) This operation ends. The above operation sets a karaoke audition game, a red and white singing battle game or a color lympics game, and sets script data (program) and image data,
The text data is read into the RAM 12. Thereby, this game is executed in the subsequent karaoke singing.

On the other hand, when the scoring game script data is read (s30), if mode = 1 to 4, the scoring game mode is currently set, and this script data is used to end the game. Means that is selected, the process proceeds from s30 to s50.

In s50, the currently executed game is determined. In the case of the karaoke audition game or the color lympics game, that is, in the case of mode = 1, 3, a display indicating that the currently executed game is to be ended is displayed (s
51), mode is set to 0 (s52), and the operation ends.

On the other hand, in the case of the red and white song battle mode, s5
The process proceeds from 0 to s53. In s53, a screen for designating whether to end as it is or to finally sing the bird singer is displayed.
The user performs a key input according to this display. If the input is that the bird does not sing, the process proceeds from s54 to s55. In S55, since the red and white singing flag is judged and set (1), the red and white singing is performed after the red and white singing is alternately performed. finish. When the red set flag is reset (0), since the red set has been sung and the white set has not been sung yet, a display indicating that the last score of the red set is canceled is displayed (s56), and the scoring is performed. After outputting to the program an instruction to cancel the last score of the red set (s57), an end instruction is output (s58).
As a result, the final score is announced on the screen shown in FIG. 18B, and the red and white song battle ends.

When the user inputs that the bird sings, the process proceeds from s54 to s59. In s59, 4 is set in the mode register mode. Then, the red set flag is determined (s60). If the red set flag is set, 1 is set to the bird counter Ct for counting the number of birds (s61), and the operation is terminated. If the red set flag is reset, the singer of the immediately preceding red set is counted as a bird, and the singer of the next white set is the second bird, that is, the last singer. Therefore, the tri-counter Ct
Is set to 2 (s62), the scoring program is instructed to count the score of the singer of the last red group three times (s63), and the operation ends.

Returning to FIG. 4, when the music number read from the reservation list is a music number other than 8000-01, 8000-02, the process proceeds to s15. In s15, the contents of the mode register mode are determined. When mode = 0, it is a normal karaoke performance mode. In the case of the normal karaoke performance mode, the process goes to s18 after the monitor 6 is set to the blue back (s16). On the other hand, in the case of the scoring game mode, after displaying a pattern including the logo of the game name as the background of the monitor 6 (s17), the process proceeds to s18.
The pattern with the game name logo is shown in FIG.
Is included in the scoring game script data read by the operation of (1).

At s18, the contents of the reservation list are displayed.
At the top of the reservation list, the title of the music data to be played is described. In the display of this reservation list, if the red and white singing battle game is set, a red microphone is displayed at the beginning of the song name of the song sung by the red set, and the white set sings. Display a white microphone at the beginning of the song title. Then, the music data identified by the music number is read out to set up the sound source device and the like (s
19). During this set-up operation, the reservation list is deleted (s20), the first (currently read) music number is deleted from the reservation list (s21), and the name of the read music data is displayed (step S21). s22). At the same time, whether the song battle game is currently set, ie, mode
= 2, 4 (s23). If the red-and-white song battle game is not set, the process waits for the completion of the setup (s27), and proceeds to the karaoke execution operation.

On the other hand, if the red and white singing battle game is set, the red set flag is determined (s24), and a screen for instructing the set to sing this song is displayed on the back of the song title (s25, 2).
6). For example, when the red set flag is 0 and the white set is singing, a screen including the phrase "Let's go to the white set!" As shown in FIG. 18A is displayed to sing to the white set singer. Urge you to This display is continued until the setup is completed (s27), and when the setup is completed, the operation proceeds to the karaoke execution operation.

The karaoke execution operation includes a progress control operation (FIGS. 8 and 9), a display control operation (FIGS. 10 to 13), and a scoring process operation (FIGS. 14 and 15). Work in parallel while exchanging.

FIGS. 8 and 9 are flowcharts showing the progress control operation. First, in FIG. 8, it is determined whether or not the current Color Olympic game is set (mode = 3) (s64). If the colorolympics game is set, after performing the initial setting operation (see FIG. 22A) (s65), the process proceeds to s66. When the colorolympics game is not set, the process proceeds directly from s64 to s66.

At s66, the data of each track of the music data is read in accordance with the clock and duration data, and if the read event data is note event data for controlling tone generation / muting of musical tones, the note data included in the event data is included. The key shift amount kc is added to the number (s67). The key shift amount kc is set to various values by a key change operation in the color Olympic game, but is always set to 0 in other modes. Then, the event data is output to the corresponding part (s68). The event data of the music track is output to the sound source device 18, the event data of the lyrics track is output to the character display unit 20, and the audio data read according to the audio track is output to the audio data processing unit 19.
The event data of the effect track is output to the control amplifier 2, and the event data of the guide melody track is converted to frequency data and volume data, and then output to the audio signal processing device 3. As a result, operations such as performance of a karaoke song, display of lyrics, and scoring are performed. This operation is continued until the music ends (s70).
While the reading operation of the music data is being continued, if the colorolympics game is set, that is, mode =
In the case of 3 (s69), the key and the tempo are changed at random (s71 to s76). If the Karalympics game is set at the start of the karaoke performance, the timing and the size of the key change and the tempo change are determined in advance by a predetermined random number process. Then, it is determined whether it is the key change timing during the reading of the music data (s71),
It is determined whether it is the tempo change timing (s74).
If it is the key change timing, the key change processing (FIG. 22)
(See (B))) (s72), and the contents of the key change are notified to the display control operation (s73). The key change is performed at once without taking an intermediate value. In the display control operation, the running character (described later) is caused to jump or crouch in accordance with the change of the key. If it is the tempo change timing (s74), a tempo change process (see FIG. 23) is executed (s75), and the content of the tempo change is notified to the display control operation (s76). It is assumed that the tempo is gradually changed according to the change range. In the display control operation, the running speed of the running character is increased or decreased according to the change in the tempo.

Here, with reference to FIGS. 22 and 23, an initial setting operation, a key change processing operation,
The tempo change processing operation will be described. FIG. 22 (A)
5 is a flowchart showing an initial setting operation executed at the time of starting a performance in a color Olympic game. First,
The original tempo data written at the head of the musical tone track is set to tm (s220). The tempo is changed within a range of half to twice the original tempo. Thereafter, a random number is generated (s221), and the random number is mapped in a range of 1 second to 30 seconds (s222).
The mapped value is set in the key change timer as the time until the key change (s223). Further, a new random number is generated (s224), this random number is mapped in the range of 1 second to 30 seconds (s225), and the mapped value is set in the tempo change timer as a time until the tempo is changed (s226). .

FIG. 9B is a flowchart showing the detailed operation of the key change process executed in s72 of FIG. First, there is a flag for storing whether or not the key has been changed from the original key. If the key has not been changed, a random number is generated to change the key (s231), and this is mapped to a range of 1 to 11 representing the number of semitones (s231).
232). The mapped value is set in the change amount register ks as a key change amount (s233). On the other hand, if the key is currently changed, 0 is set in the change amount register ks to return the key to the original key (s2).
37). When the next sounding event data is read
At 67, the changed amount ks of the changed setting is added to the note number, sent to the sound source, and the key is changed.

Thereafter, a new random number is generated (s23
4) This random number is mapped in the range of 1 to 30 seconds (s235), and the mapped value is set in the key change timer as the time until the next key change (s23).
6).

FIG. 23 is a flowchart showing the detailed operation of the tempo change process executed in s75 of FIG. A random number for changing the tempo is generated (s240) and mapped to a range of -50 to +50 representing the change ratio (s2).
41). The current tempo set value ts is multiplied by the mapped value as a percentage to calculate a new tempo set value, which is written to the tempo set register ts (s24).
2). This ts is twice to 1/2 of the original tempo tm
Is determined to be within the range (s243), and if not, it is corrected to fall within this range (s243).
244). This correction may be a double cut if the original tempo is more than twice, or a half cut / foot cut processing if the original tempo is less than 1/2. A new value may be obtained by wrapping the part in the range. For example, if a tempo of 240 is calculated for a song with an original tempo of 100, 40, which exceeds 200, which is twice the original tempo, is calculated as 2
The value 160 calculated by looping back (subtracting) from 00 is set as the corrected tempo set value. Various correction methods other than this can be applied. The performance tempo is corrected to the new tempo set value ts thus determined (s
245). For this correction, the frequency of the tempo clock that ticks the tempo may be corrected in accordance with this. The basic clock is left as it is, and the time of one count of the timing data for controlling the read timing of each track of the music data is changed. You may make it correct. The fix isn't made at once, but rather gradually over a few seconds.

Thereafter, a new random number is generated (s24
6) The random number is mapped in the range of 1 to 30 seconds (s247), and the mapped value is set in the tempo change timer as the time until the next tempo change (s24).
8).

In FIG. 9, when the song ends (s7
0), the end of the music is notified to the display control program and the scoring processing program (s77), and the current mode is determined (s78). In the case of the normal karaoke performance mode and the color lympics mode, the progress control operation is terminated as it is. In the case of the color selection mode, the display control program and the scoring processing program execute the operation of presenting the result. In addition, the karaoke audition game is charged and requires a fee. First, the scoring processing program and the display control operation are temporarily stopped (s79), and it is determined whether or not the charging device 9 has a credit (s80). If there is a credit, the credit is subtracted to restart the operation of the scoring processing program / display control program (s8).
3). If there is no credit, a message indicating that credit should be inserted is displayed (s81). If a credit is inserted in response to this, the process proceeds from s82 to s83. If no credit is inserted, the mode is returned to 0 (s8
4) End the operation.

On the other hand, when the red and white singing battle game is set (mode = 2, 4) (s78), it is determined whether the mode is the end mode, that is, whether it is the bird's turn to sing (s85). If the mode is not the end mode, 1 is added to the interim announcement counter Cm for performing an interim announcement after performing 6 songs (s86), and it is determined whether or not Cm = 6 by this addition (s87). When Cm = 6, an intermediate presentation is instructed to the scoring processing program and the display control program (s88). And clear Cm (s8
9) Invert the red set flag (s90). If Cm is not 6, the process proceeds directly from s87 to s90, and only the inversion of the red set flag is completed to end the operation.

Also, the end mode (mode) of the red and white song battle
= 4), 1 is added to the tri counter Ct (s
91). If Ct = 3 as a result of this addition, it indicates that the birds in both the red and white groups have finished singing, and instructs the scoring program and the display control program to make a final announcement (s93). Then, 0 is set in the game mode register mode.
Is set (s94) to end the operation.

FIGS. 10 to 13 show a display control operation (display control program) executed in parallel with the above-mentioned progress control operation.
It is a flowchart which shows. This operation is started by taking over the screen control to be displayed on the monitor 6 from the display of the music title in s22 of the data reading operation. First, a background image is started by transmitting background image selection data such as a chapter number to the LD changer 4 (s1).
00). Next, the contents of the mode register mode are judged (s81). If mode = 0, that is, if the mode is the normal karaoke performance mode, the process proceeds to s102. At s102, event data (character display data) of the lyrics track read by the progress control program is input, a character pattern is generated according to the data, and superimposed on the background image (s102). As a result, the background image and the lyrics are displayed on the monitor 6. This operation is continued until the music ends (s103), and when the music ends, the LD changer 4 is instructed to stop the background image (s104) and the operation ends. On the other hand, if the mode is not 0 in s102, the process proceeds to the display control operation of FIGS. 11 to 13 according to the game mode.

FIG. 11 is a flowchart showing a screen control operation in mode = 1, that is, a karaoke audition game. First, an animation of the face of the judge (judging committee chair) shown in FIG. 17A is displayed on the background video whose reproduction has been started in accordance with the instruction of s100 (s1).
05). At the start of the performance, a normal facial animation is displayed. Thereafter, based on the lyrics data input from the progress control program, the superimposed display of the lyrics is executed (s106), and it is determined whether the phrase point is input (s107) or the song ends (s110). . The phrase point is a score for each phrase of the karaoke song calculated by a scoring processing program described later, and is calculated for three elements of pitch, volume, and rhythm. When a phrase point is input (s10
7) The judge's face animation is changed according to this point (s108). The animation is changed so that the smile becomes high when the section point is high, and the face becomes frown when the section point is low. At the same time, an advisory word is displayed in a balloon so that the defect of the singing can be corrected (s109). The advice wording indicates "good", "not good or bad", "poor pitch", "poor tempo (rhythm)", "poor volume / no voice", "all bad" Six types are prepared, and each of them has words like advice such as "Speak out louder!" Or "Be careful about the pitch!"

When the music ends (s110), the LD changer 4 is instructed to stop the background image (s11).
1) The display score is input from the scoring processing program (s112). The display on the monitor 6 is switched from the background video screen to the result presentation screen shown in FIG. 17B, and the display score is displayed (s113). When the total score, which is the average of the three display scores, is 95 or more (s11
4) Display a million seller blessing screen with the illustration of the gold disk (s115).

FIG. 12 is a flowchart showing the operation of the display control program in the red-and-white song battle game of mode = 2 or 4. The operation starts after the karaoke starts and the background image starts (s100: FIG. 9). First, the red set flag is determined (s120). If the red set flag is set, then it is the turn for the red set to sing, and the animation of the red set leader is displayed (s12).
1). On the other hand, when the red set flag is reset, the white set is the singing turn, and thus the animation of the white set leader is displayed (s122). The leader's animation is displayed at the top right of the screen. The lyrics are superimposed and displayed in accordance with the lyrics data input from the progress control program (s123), and the animation of the reader is moved in accordance with the rhythm of the music (s124). That is, the leader's face is moved so as to swing right and left in accordance with the rhythm.
These display control operations are executed until the music ends (s125).

When the music ends (s125), an instruction to stop the background image is given to the LD changer 4 (s126).
It is determined whether an intermediate announcement or a final announcement has been instructed from the progress control program (s127, s129). In the case of an interim presentation, the score of the interim total is received from the scoring processing program and displayed (s128). The interim announcement is displayed on a screen as shown in FIG. Further, when the final presentation is instructed (s129), the final total score is received from the scoring program, and the result is presented on a screen similar to the above-mentioned intermediate presentation screen (s130). ), Beni-gumi winning screen (s132),
White group win screen (s133) or draw screen (s
134) is displayed.

FIG. 13 is a flow chart showing the mode = 3, that is, the display control operation at the time of the color Olympic game. First, a running animation is displayed on the background video that has been started to be reproduced according to the instruction of s100 (s14).
0). This running animation is shown in FIG.
This is an animation in which (A) and (B) are alternately displayed to make the character appear to be running, and are displayed on the upper right of the monitor 6. Then, the lyrics are superimposed and displayed according to the lyrics data input from the progress control program (s141). Then, it is determined whether a tempo change or key change instruction is input from the progress control program in s14.
2, s143, s146, and s147. When a tempo up instruction is input (s142), the running pitch is increased according to the tempo up (s144). When a tempo-down instruction is input (s143), the running pitch is delayed according to the tempo-down (s145). When the key-up instruction is input (s146), the running animation is jumped once (s14).
8). This jump is realized by inserting a running animation (FIGS. 19A and 19B) into the illustration of FIG. 19C. When the key-down instruction is input (s127), the running animation is crouched once (s129). This squatting operation is realized by inserting the illustration of FIG. 19D into the running animation (FIGS. 19A and 19B). This display control is continued until the song ends (s150).

When the music is completed (s150), the CPU instructs the LD changer 4 to stop the background image (s151).
Input the display score from the scoring processing program (s15
2) The display score is displayed on the monitor 6 (s15).
3). This score is a maximum of 10.0. In accordance with this score, a screen for awarding gold medals and a screen for awarding silver medals and bronze medals shown in FIG. 20A are displayed (s154 → s
155) If the score is less than the medal award, FIG.
(B) Display the "Return home while crying" screen (s15
6).

FIGS. 14 and 15 are flowcharts showing the operation of the scoring processing program. Of this operation, s16
0 to s163 indicate the operation of the audio signal processing device 3. The audio signal processing device 3 receives the frequency data and volume data of the guide melody from the progress control program (s160), and inputs the singing voice signal of the singer from the control amplifier 2 (s161). Then, the frequency and volume of the singing voice signal are analyzed (s162),
The frequency difference data and the sound volume difference data are calculated by comparing the frequency data and the sound volume data (s163). The difference data is input from the audio signal processing device 3 to the CPU 10. The CPU 10 determines the rising timing difference of the volume data, that is, the rhythm difference data, based on the frequency difference data and the volume difference data (s164). Then, the frequency difference data, the volume difference data, and the rhythm difference data are integrated in the difference data buffer (s165). The above operation is executed every 150 ms during the karaoke performance. When the end of the phrase is detected, the process proceeds from s166 to s167. A phrase is a segment of a song, and can be determined based on that the volume of the guide melody has become zero. Also,
Data indicating the delimiter of the phrase may be embedded in the music data, and the process may proceed from s166 to s167 based on the data.

When the phrase ends, the phrase points of the frequency (pitch), volume and rhythm of the phrase are calculated (s167). This point is calculated by a deduction method in which a deduction value is calculated from the integrated value of the difference data, and the deduction value is subtracted from the full score. The phrase points are accumulated and stored (s168), and the mode is
= 1, that is, when the karaoke audition game is being executed, the phrase point is output to the display control program operating in parallel (s170).
In this display control program, the expression of the chairman of the examination committee is changed based on this phrase point, and the advice wording is displayed. After this, until the song ends (s17
1) The difference data buffer is cleared for each phrase (s172), and the process returns to s160. When the song ends (s
171) By averaging the phrase points of all the phrases, all music points of frequency (pitch), volume and rhythm are calculated (s173). Then, according to the game being executed, all the music points are processed into display scores (s174 and below). First, the mode register mod
e is determined (s174), and if mode = 1, that is, if it is a karaoke audition game, the operations of s175 to s178 are executed. If mode = 2,4, that is, a red and white song battle game, the operations of s180 to s187 are executed.
Further, if mode = 3, that is, if the game is a color Olympic game, the operations of s190 to s193 are executed.

In the karaoke audition game,
In s175, three kinds of display scores are calculated by performing weighted averaging of all music points of frequency, all music points of volume, and all music points of rhythm (s175). This display score is displayed by the three judges described above, and is calculated with different weights. Furthermore, a total score obtained by simply averaging the three display scores is also calculated. Then, it is determined whether the karaoke audition game is started with a song number of 8000-01 or 8000-02 (s176).
If it started with a song number of 8000-02,
The calculated display score is raised (s177). The formula for calculating the raising score may be calculated as “original display score” × 0.6 + 40 in order to raise the maximum by 40%.
The display score thus calculated is output to the display control program (s178).

In the red and white song battle game, s18
At 0, it is determined whether the bird is in the ending mode for singing. In the end mode, the score is calculated out of 300 points by averaging all three music points of frequency, volume and tempo (s18).
2). Otherwise, the score is calculated out of 100 points by averaging all three music points (s181). Then, the red set flag is determined (s183). If the red set flag is set, this score is added to the red set score counter (s184). If the red set flag is set, this score is added to the white set score counter. Is added (s185). Then, it is determined whether or not an instruction for an intermediate announcement or a final announcement has been input from the progress control program (s186), and when these instructions have been input, the scores stored in the red group score counter and the white group score counter are displayed. Output to the control program (s187).

In the Karalympics game, s190
Then, the score for display is calculated by averaging all music points of frequency, all music points of volume and all music points of rhythm. This score is calculated to the first decimal place with a perfect score of 10.0. And this karalimpic game is 8000-0
Start with the song number 1 or 8000-02
It is determined whether or not the program started with the music number (s19).
1) If the program starts with a music number of 8000-02, all points are raised (s192). This raising calculation may use the same calculation as in the karaoke audition game. The display score thus calculated is output to the display control program (s193).

Thus, in the karaoke audition game and the Karalympics game, the score is displayed each time the performance of the karaoke song is completed, and in the red and white singing battle game, the total score of the red and white groups is displayed at the time of the intermediate or final announcement. Is done.

In the above embodiment, the key is changed at a stroke to the target value, and the tempo is gradually changed to the target value. However, the key may be changed gradually and the tempo may be changed at a stroke. You may.

The key and tempo change instructions are given in the animation in which the character is running. In the case of a key change, the character is jumped or crouched one second before the change, and in the case of a tempo change, the running is performed during the change. The pitch is increased or decreased, but the display form is not limited to this.

In the above-mentioned Karalympics game, a medal is awarded according to the score sung by one person. A plurality of people sing in order, and a gold medal is given to the one with the best score. A plurality of singers may compete, for example, by giving a silver medal to the second one and a bronze medal to the third one.
