DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for calculating calorie consumption by singing based on music generation data which is the origin of karaoke accompaniment music, and a karaoke apparatus for calculating and displaying calorie consumption by the method. .

[0002]

2. Description of the Related Art A karaoke apparatus processes karaoke data in which music generation data which is the origin of karaoke accompaniment music and lyric rendering data which is the origin of a lyric image are processed to synchronize the karaoke accompaniment music with the lyric image. Audio / video output. The karaoke apparatus can be said to be a computer system for a specific application, focusing on the basic function of performing karaoke music. However, its data processing function is too advanced to be used only for performance processing. Actually, game functions such as an intro guessing quiz that plays only the beginning of the music, a scoring function that analyzes and sings the singing voice from the microphone, and various data held by the host computer connected to the network ( It has a function as a data terminal for presenting users with rankings of popular songs and commercial information. Current karaoke devices continue to evolve as intelligent entertainment systems by utilizing network resources and hardware resources.

[0003]

Most images of karaoke can be described as cultural entertainment in a closed space. However, singing in karaoke, especially intense diaphragm activity due to abdominal breathing, is a general exercise of the body and requires considerable calorie expenditure. The present inventor paid attention to this fact, and wanted to make this fact known not only to karaoke users but also to many people, and to use karaoke for exercise promotion and healthy dieting.

[0004] For this purpose, it is considered most effective to calculate the standard calorie consumption when singing one karaoke song and notify the user of the calculated calorie consumption. Moreover,
We want to calculate each song individually so that each singer can be a target of calorie consumption.

When calculating the standard calorie consumption, there is also a method of calculating (measuring) calorie consumption from heart rate, respiration rate, etc. by actually singing each song (by a typical singer such as a singer). is there. However, it is clear that a huge amount of music requires a great deal of time and money. In addition, recent karaoke devices have two songs that are number three.
Various performance modes can be set, such as rounding up at the turn or performing at a different tempo. If singing along with the accompaniment music in the various performance modes, the calorie consumption naturally changes. Therefore, the reason why the standard calorie consumption is unambiguously determined in advance is a large error from the actual calorie consumption.

Accordingly, the present invention can estimate the standard calorie consumption by singing without needing advanced calculations and complicated measurements, and moreover, can flexibly calculate the calorie consumption even when the performance mode is changed. It is an object of the present invention to provide a karaoke apparatus which can display a standard calorie consumption by adopting the method and the method.

DESCRIPTION OF THE PREFERRED EMBODIMENTS === Basic Configuration and Operation of Karaoke Apparatus === FIG. 1 shows a karaoke apparatus according to an embodiment of the present invention. The central control unit 11 has a CPU, RAM, R
It is a microcomputer including an OM, and performs data communication with peripheral components via a data bus 100 and a control bus 110 to control / control the karaoke apparatus 1. The hard disk device 12 stores various programs for realizing ancillary functions such as a singing game, in addition to karaoke data for many songs. The karaoke data is music generation data that is the origin of karaoke accompaniment music described in the MIDI format, lyrics characters to be drawn in synchronization with the music performance, and attributes of the characters (display position, display color, display / erase timing). Is described.

When the central control unit 11 receives an ID input of the requested music from the remote control transmitter 17 or the operation panel 18 via the operation control unit 19, it stores the input order and the ID in the RAM in association with each other, and stores the music in the RAM. Of performance reservation.
Then, karaoke data of the corresponding music is taken out according to the reservation order. Then, the MIDI data is transferred to the synthesizer 13. The synthesizer 13 controls a built-in sound source according to the MIDI data and generates karaoke accompaniment music. The audio signal of the karaoke accompaniment music output from the synthesizer 13 is mixed with the singing audio signal from the microphone 15 by the mixing amplifier 14 and is output as sound to the speaker 16.

It should be noted that karaoke accompaniment music can be output as sound in various performance modes. More specifically, the karaoke accompaniment music is changed to a key or tempo that is changed by a user's operation, or a system setting such as a maintenance worker is used to fade out a tune of number 3 or more with the number 2 and finish the process halfway (2 chorus fade-out). ) Mode.

On the other hand, lyrics rendering data is processed in synchronization with the karaoke accompaniment music generation processing, and a bitmap image corresponding to the lyrics image is developed in the video RAM 20. The video controller 21 superimposes the bitmap image on the mood video output from the video CD changer 22 and outputs the video to the display 23.

The karaoke apparatus 1 of the present embodiment calculates the amount of calories expected to be consumed when a singer sings a designated music piece, and calculates the standard calorie consumption for displaying and outputting the calculation result as the standard calorie consumption. It has a quantity calculation function. Further, a singing calorie consumption calculating function is provided, which can calculate the amount of calories consumed when the singer actually sings by measuring the volume of the singing voice.
Programs for realizing these functions are stored in the hard disk device 12, and the central control unit 11 reads and processes predetermined program data when the execution of these functions is specified.

=== Calculation Method and Processing of Standard Calorie Consumption Amount === Music generation data is generated for each sound source corresponding to each musical instrument built in the synthesizer 13, pitch, volume, sounding / muting timing of the sound, and Note characteristics such as time to note (note length) are described along the performance time series. By giving the note characteristic data to the synthesizer 13, a predetermined sound with a predetermined timbre is generated at a predetermined volume for a predetermined time. The music generation data includes a melody of a predetermined musical instrument as a melody corresponding to a vocal (main melody). In this embodiment, the standard calorie consumption is calculated based on the note characteristic data on the main melody. Central control unit 11
Extracts a data portion corresponding to the main melody from the corresponding music generation data prior to the performance of this music when a performance instruction of a certain music is input. Then, note characteristic data of each note on the melody is acquired and processed. Hereinafter, the processing will be described.

The data that is necessary only for the calculation of the calorie consumption is the volume of each sound of the main melody and the sounding duration (the time between the sounding timing and the silence timing), and the pitch is not so related. FIG. 2 shows an outline of the calculation processing of the standard calorie consumption. The central control unit 11 associates the volume and the duration of each sound on the main melody with the performance time series. In the graph, the vertical axis represents the volume and the horizontal axis represents the time. Next,
The volume is time-integrated over a section corresponding to the singing part. This integration result corresponds to the area of the polygon formed by the volume broken line in the graph. Then, the area is multiplied by a predetermined calorie conversion coefficient to obtain a standard calorie consumption.

Here, the calorie conversion coefficient is a numerical value obtained by measuring the calorie consumption corresponding to the physical exercise when a person having a standard physique sings a music piece normally (accurately according to the note characteristic data). And a coefficient for matching the result of the integration calculated based on the music generation data of the music. As an example of a method of obtaining the coefficient, there is a method of measuring the amount of oxygen consumed by singing to obtain the calorie consumption. For example, using a device for measuring oxygen consumption, such as that disclosed in Japanese Patent Application Laid-Open No. 5-212136, a tune of a person of a standard physique is sung accurately according to the note characteristic data. Of course, you don't have to sing the whole song. The above integrated value (area) is obtained from the note characteristic data on the main melody corresponding to the part sung by the person. When the actually measured calorie consumption (value) is divided by this integral value, the calorie consumption per unit area (unit volume × unit time) is obtained. This is defined as a calorie conversion coefficient (coefficient A).

Further, a calorie conversion coefficient (coefficient B) for calculating the amount of calories consumed when singing karaoke may be calculated first (the method of obtaining the coefficient B will be described later). In this way, the calorie consumption when singing according to the note characteristic data can be estimated.

The standard calorie consumption thus obtained is displayed on the display at an appropriate time, such as immediately before the performance of the designated music piece, by the central control unit 11 executing an appropriate drawing process. FIG. 3 schematically shows the display state.

=== Calculation of Singing Calorie Consumption === The karaoke apparatus 1 is provided with a volume detecting section 24 in order to realize the singing calorie calculation function. Volume detector 24
Has a built-in A / D converter, samples the volume (signal amplitude) level from the microphone 15 every minute time (for example, about 0.2 seconds), and sequentially transfers it to the central control unit 11 as digital volume data. FIG. 4 shows the outline of the volume level data.

The central control unit 11 calculates the calorie consumption by integrating and processing a numerical value obtained by multiplying the volume data received every minute time by predetermined calorie conversion data.
The calorie conversion coefficient here corresponds to the coefficient B described above.
The method of obtaining the coefficient B is basically the same as that of the calorie consumption calculation based on the measurement of the oxygen consumption described above. First, a person with a standard physique speaks into the microphone. At this time, the volume level from the start of the utterance to the end of the utterance is measured every minute time. The measured value for each minute time is integrated over time. By dividing the measured calorie consumption by this integral value, the calorie consumption per unit area can be obtained. This numerical value is the coefficient B. Therefore, the singing calorie consumption can be obtained by multiplying the time-integrated volume level received at each minute time by this coefficient B. Therefore, calorie consumption increases as singing with a loud voice or continuing to utter. If the calorie consumption when this person sings according to the musical note characteristic data of a certain music piece is measured, it becomes the standard calorie consumption.

The singing calorie consumption calculated in this way is output to the display at a suitable time after the performance. At this time, if the standard calorie consumption is displayed again, it can be compared with the standard value.

=== Other Application Examples / Modification Examples === Each sound of the main melody includes a flat sound and a sound that changes with a predetermined envelope. Accurate standard calorie consumption can be calculated by taking into account the volume displacement due to the envelope, but may differ from the characteristics of the human vocal cords depending on the type of instrument set for the main melody. Therefore, in the above embodiment, the calculation is performed without including the volume displacement due to the envelope.

In the above embodiment, the standard calorie consumption for one song is displayed prior to the performance, but the standard calorie consumption from the start of the performance to the current time during the performance is displayed in correspondence with the performance time series. You may do it. For this purpose, the central control unit may sequentially acquire the note characteristic data on the main melody when transferring the music generation data to the synthesizer, and calculate the calorie consumption in synchronization with the performance processing. Alternatively, the calorie consumption may be calculated before the music performance in association with the performance time series, and the corresponding calorie consumption may be displayed at each performance time.

The singing calorie consumption may be displayed and output while being sequentially accumulated in synchronization with the performance processing. At this time, if the standard calorie consumption is also displayed, the singing calorie consumption can be obtained not as a result but as a guide for achieving the target calorie consumption during singing. It is even more effective to display the integrated value of the standard calorie consumption in real time.

Some karaoke songs have a plurality of singing parts, such as duet songs. In this case, by calculating the standard calorie consumption for each part based on the corresponding main melody, the singer responsible for each part can be notified of the standard calorie consumption for each singing part individually.

When changing the tempo setting or setting the 2 chorus fade-out mode,
By appropriately increasing or decreasing the note length of each note on the main melody, or changing the time integration section, the standard calorie consumption corresponding to the performance mode can be calculated.

Of course, the method for calculating the standard calorie consumption based on the music generation data is not limited to the karaoke apparatus, but can be applied to a general-purpose computer. For example,
If the standard calorie consumption is calculated at the same time when music production data is produced on a personal computer or the like, the calorie consumption can also be posted in the table of contents of karaoke songs. Of course, the standard calorie consumption can be distributed as data to a performance terminal of the communication karaoke system via a network. If this data is associated with each song, the karaoke device does not need to calculate each time a performance is designated.

[0032]

According to the present invention, it is possible to estimate the calorie consumption by singing to actively promote the healthy aspects of karaoke music. Since the calculation is performed based on the music generation data, it is not necessary to actually measure each music using an advanced measuring device. Therefore, cost and time can be greatly saved.

If the function of calculating the standard calorie consumption by this method is adopted in the karaoke apparatus, the calorie consumption can be displayed and output at the time of playing the designated music piece. for that reason,
The singer can know the standard calorie consumption when singing the designated music without preparing a table or the like in which the standard calorie consumption is associated with each song.

If the standard calorie consumption is displayed for one song at a time, the calorie consumed by the singer can be grasped in advance. If the progress is displayed during the performance, the singer can know at which point the target calorie consumption has been achieved.

By calculating the standard calorie consumption for each main melody of the singing part, the standard calorie consumption can be individually notified to a plurality of singers corresponding to duet songs and the like. Also, if the calculation is appropriately made according to the performance mode, the standard calorie consumption can be accurately calculated.
