Problems to be solved by the invention

[0003] Accordingly, an object of the present invention is to provide a game machine capable of reflecting the tempo of music to be played back by a music playback signal output from a music playback device power in game control.

Means for solving the problem

[0004] The game machine of the present invention receives an input operation by a user and outputs an operation input unit that generates a pulse signal in response to the input operation, a display unit that displays a predetermined image, and a music playback device. A signal input unit that captures a music playback signal, a signal processing unit that outputs an integrated value of a low-frequency component of the music playback signal captured by the signal input unit, and a signal processing unit based on the output integral value. A tempo discriminating unit that discriminates the tempo of music to be played back by the music playback signal, and an input operation to the operation input unit is evaluated based on the tempo discriminated by the tempo discriminating unit. A game control unit for controlling the game; A storage unit that stores the evaluation and display image information relating to an image to be displayed on the display unit in accordance with the evaluation, and the game control unit includes the tempo determination unit. Based on the degree of coincidence between the tempo determined in this way and the tempo signal obtained from the pulse signal, the evaluation unit performs the evaluation, and the display image information associated with the evaluation by the evaluation unit The above-described problem is solved by including a display control unit that displays an image according to the above on the display unit.

According to the inventors' investigation, it is possible to extract a waveform component having a feature correlated with the tempo of music by integrating the low frequency component of the music playback signal output by the music playback device. Was found. The game machine of the present invention uses such a property, and since the integrated value of the music playback signal taken into the signal input unit is output as a signal processing unit, the integrated value waveform is characterized. By paying attention, it is possible to determine the tempo of music.

[0006] In the game machine of the present invention, a game based on the determined tempo is executed as described above. Specifically, the user operates the operation input unit at the tempo of the music while listening to the music played by the playback device, and the tempo obtained by the input operation and the tempo determined by the tempo determination unit. It is a game that makes an evaluation based on the degree of coincidence. In addition, the display control unit of the game control unit displays an image according to the evaluation, thereby enhancing the interest of the game. Therefore, it is possible to provide a game that uses the tempo of the music while listening to the music just by listening to the music output from the music playback device, thereby integrating the music and the game. Play can be provided to users. Moreover, the music playback device can select and play any music, so that it can play a variety of music compared to the case where the game is controlled according to the music tempo prepared in advance on the game machine. You can enjoy the game as a material.

[0007] The tempo discriminating unit may output the discriminated tempo as a pulse signal based on the tempo, or may output it as a value indicating the number of beats in a predetermined time. The output of the music for the user to listen to may be output directly from the power of the music playback device, or may be output from the output unit provided with a music playback signal output unit in the game machine. The operation input section may be any form such as a push button, keyboard, or string. The degree of coincidence is determined by the tempo discrimination unit It is only necessary to indicate the consistency of the tempo signal and the tempo signal obtained by the input operation in a predetermined unit.For example, the number of matches or the ratio of matches may be used. But! / The evaluation corresponding to the degree of coincidence can be determined by a predetermined formula, graph, association table or the like in which the degree of coincidence is associated with the evaluation. The correspondence between the evaluation and display image information is the same.

[0008] The storage unit stores each of the plurality of levels indicating the evaluation in association with the display image information of an image to be displayed at each level, and the evaluation unit stores the in-game The level is determined in accordance with the change in the degree of coincidence, and when the level change occurs, the display control means displays an image displayed on the display unit with an image power corresponding to the level before the change. You may switch to the image corresponding to the level after the change.

[0009] As a result, images corresponding to each level are prepared, and when the level changes as the degree of coincidence changes during the game, the image displayed on the display unit changes from the image corresponding to the level before the change. Switch to the image corresponding to the later level. This allows the user to check the current level and also recognize when the level changes. Since the level is gradual, it is possible to add an impact to level changes by displaying images that are clearly different between each tier. In addition, since an image corresponding to the level may be prepared, it is possible to cope with even a small and simple game machine by setting the number of levels according to the storage capacity of the game machine. The “image corresponding to the level” means “an image based on display image information corresponding to the level”.

[0010] The degree of coincidence may be the number of coincidence between the determined tempo and the tempo signal obtained by the pulse signal. In this case, the degree of coincidence can be easily obtained by simply counting the number of coincidence between the determined tempo and the tempo signal obtained by the pulse signal.

[0011] The storage unit further stores insertion image information relating to an insertion image that is instantaneously inserted into the display unit, and the display control unit is configured to switch the insertion image when switching an image corresponding to the level. An image based on information may be instantaneously displayed on the display unit. As a result, the level change can be further impacted, and the user's sense of exaltation can be enhanced. The inserted image may be an image that fills the display area or may be displayed. It may be an image displayed on a part of the part. In addition, the inserted image may be displayed before or after the image is switched according to the display image information.

[0012] Further, the inserted image differs depending on the level, and is stored in association with the corresponding level, and the display control unit is stored in association with the changed level at the time of the switching. An image based on the inserted image information may be displayed on the display unit. This makes it possible to instantaneously display different insertion screens for each level, and to enhance the feeling of the user's feelings for level up.

[0013] The storage unit further stores level information indicating the current level of the user, and the evaluation unit counts the number of matches, and the level of the number of matches indicates the level of the level information. When the level information is exceeded, the level is determined by updating the level information, and the display control unit controls the display of the display unit by using the level information update by the evaluation unit as a change in the level. Moyo. Since the level information in the storage unit is always updated to the current level by the evaluation unit, the display control unit can recognize the current level by referring to the level information.

[0014] The display image information may be set to display an image in which a character's motion mode is different for each level. The mode of movement includes all movements such as dance, exercise and movement in daily life. For example, to display a dancing character

This makes it possible to produce the feeling of dancing with the character to the music in the game.

[0015] The evaluation unit performs an evaluation based on the degree of coincidence within a predetermined range in the game, and the display control unit associates with the evaluation of the evaluation unit at the end of the predetermined range. An image based on the displayed display image information may be displayed. Thereby, an image corresponding to an evaluation within a predetermined range during the game can be displayed. The predetermined range in the game includes a song unit range and a time unit range.

[0016] The evaluation unit counts the number of coincidence between the determined tempo and the tempo signal obtained by the input operation as the degree of coincidence in the predetermined range, A coincidence rate, which is a ratio of the coincidence number to the number of input operations to the operation input unit in a predetermined range, is calculated as the evaluation, and the storage unit calculates the coincidence rate, The image information relating to the image to be displayed on the display unit is stored in association with each other, and the display control unit uses the display image information according to the matching rate calculated by the evaluation unit at the end of the predetermined range. An image may be displayed on the display unit. Thereby, evaluation according to the coincidence rate in a predetermined range can be performed, and an image according to the evaluation can be displayed.

[0017] The unit of the predetermined range is a song, and the game control unit includes an end determination unit that determines the end of the song based on the presence or absence of the music playback signal taken in via the signal input unit. It may be. As a result, the end of the song can be determined only by the audio reproduction signal, and the degree of coincidence can be evaluated for each song. Note that “based on the presence / absence of an audio reproduction signal” includes determination based on the presence / absence of the audio reproduction signal itself and determination based on the presence / absence of various signals generated from the audio reproduction signal.

[0018] The display image information may be set to display an image in which the facial expression of the character is different for each level. The facial expressions include “smile” and “cry face”. For example, the higher the level, the greater the degree of smile, which can produce user satisfaction.

[0019] Further, the tempo determination unit can determine the tempo by extracting a feature correlated with the tempo of the music from the integrated value output from the signal processing unit. The low-frequency component of the music playback signal is strongly influenced by the regular bass rhythm contained in the music, and if this is integrated, the irregular fluctuations contained in the low-frequency component are blunted and the regular bass rhythm Changes appear more clearly. Therefore, it can be considered that the cycle in which the integrated waveform changes has a strong correlation with the music tempo, and if the fluctuation cycle is extracted as a feature, a powerful clue to discriminate the music tempo is obtained. be able to. The fluctuation period can be known, for example, by obtaining the peak value interval of the integrated waveform, in other words, obtaining the time interval of the maximum value.

[0020] Further, the game machine of the present invention is interposed between a line output terminal of the music playback device and a sound output device for converting the music playback signal output from the line output terminal force, A bypass path for passing the music playback signal output from the line output terminal to the audio output device; and a path for taking the music playback signal into the signal processing unit. May be. According to such an embodiment, the music playback signal output from the line output terminal of the music playback device is passed through the audio output device to play the music, and the user can play a game synchronized with the tempo of the music. Can do.

The invention's effect

[0021] As described above, according to the game machine of the present invention, the tempo determined based on the integrated value of the low frequency component of the music reproduction signal is reflected in the control of the game. It is possible to provide a game that uses the tempo of the music while listening to the music just by listening to the output music, thereby providing the user with a novel game that fuses the music and the game. be able to. In addition, the music playback device can select and play any music, so that it can be used for various types of music compared to the case where the game is controlled according to the music tempo prepared in advance in the game machine.

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 illustrates a portable game machine according to one embodiment of the present invention. The game machine 1 is used in combination with the portable music player 100, and includes a housing 2 and an LCD 3 as a display device attached to the front surface of the housing 2. The case 2 is provided with a line input terminal 4 and a phone terminal 5. The line input terminal 4 is connected to the line output terminal 101 of the portable music player 100 via the relay cable 102. The phone terminal 5 is connected to the earphone 103. That is, the game machine 1 of this embodiment is used by being interposed between the portable music player 100 and the audio output device to be combined therewith. The audio output device combined with the music player 100 is not limited to the earphone 103. That is, the portable music player 100 is not particularly limited as long as it can output a music reproduction signal for audio conversion to various audio output devices such as speakers and headphones. It doesn't matter. Furthermore, the music player is not limited to a portable player, and may be any device that outputs music in home audio, television, and commercially available portable electronic games.

The housing 2 is further provided with an input button 6 as an operation input unit that receives an input operation by the user. The input button 6 is a push button, and the user performs various selections and inputs related to the game performed in the game machine 1 by pressing the input button 6 as an input operation. The game machine 1 functions as a relay that passes the music playback signal output from the line input terminal 4 of the music player 100 to the earphone 103, and also analyzes the music playback signal output from the music player 100, Based on the analysis result and the input of the input button 6, it functions as a game machine that provides the user with a game.

FIG. 2 is a block diagram showing a configuration of a control system provided in the game machine 1. Game machine 1 has a bypass path R1 for passing an analog audio reproduction signal from line input terminal 4 to phone terminal 5 as a signal input section, and an audio reproduction signal captured from line input terminal 4 via branch path R2. And a control unit 11 for capturing the output signal of the signal processing unit 10. Routes Rl and R2 are both on the right It consists of three lines, a channel, a left channel, and an earth channel.

[0026] The signal processing unit 10 includes a low-pass filter (LPF) 12 that passes only the low frequency component of the music reproduction signal captured from the line input terminal 4, and an integration circuit 13 that integrates the low frequency component that has passed through the LPF 12. And an AZD converter 14 that converts the output signal of the integration circuit 13 into a digital signal and outputs the digital signal to the control unit 11. The frequency range that LPF12 passes is set to 1000Hz or less, for example.

[0027] The control unit 11 is configured as a converter unit in which a microprocessing unit (MPU) and peripheral devices necessary for the operation of the MPU, for example, a storage device 25 such as a RAM and a ROM, are joined together. In addition to the LCD 3 and the input button 6 described above, a speaker unit (SP) 20 for generating sound, sound effects, and the like is connected to the control unit 11, and a phone terminal is connected to the connection path to the speaker unit 20. 5 is also connected. The input button 6 is a push button. When the input button 6 is pressed as an input operation, a pulse signal is generated in synchronization with the press operation, and the pulse signal is output to the control unit 11 as an input signal. The storage device 25 holds various programs and data necessary for realizing the present invention.

[0028] The control unit 11 provides various game functions to the user by executing processing such as displaying a game screen on the LCD 3. As a function attached to the game, the control unit 11 also has a function of analyzing the output signal of the signal processing unit 10 and determining the genre of music. When the control unit 11 reads a predetermined control program from the storage device 25 and executes it, a tempo determination unit 30 and a game control unit 31 are generated as logical devices inside the control unit 11. The tempo discriminating unit 30 discriminates the output signal power music tempo of the signal processing unit 10 and gives the discrimination result to the game control unit 31.

The game control unit 31 includes an evaluation unit 31a, a display control unit 3 lb, and an end determination unit 31c, and executes a game according to a predetermined game program (not shown). The game control by the game control unit 31 reflects the tempo discrimination result. Hereinafter, the game controlled by the game control unit 31 is referred to as a tempo game. The function of each unit and the tempo game that the game control unit 31 has will be described later. In the game control unit 31, the tempo discrimination unit 30 If the input of the strong tempo discriminating result is not continued for a predetermined time, for example, 2 seconds, it is judged as silent, and if the tempo discriminating result from the tempo discriminating unit 30 is continued, it is judged as silent. to decide.

Next, processing related to tempo discrimination by the game machine 1 will be described with reference to FIG. 3 and FIG. FIG. 3 shows a tempo discrimination processing routine executed by the tempo discrimination unit 30 of the control unit 11. When an integral value signal is output from the signal processing unit 10, the output signal is sequentially captured and stored in the internal buffer of the control unit 11. The tempo discriminating unit 30 sequentially processes the signal of the integrated value stored in the internal buffer by repeatedly executing the tempo discriminating routine of FIG. 3 at a predetermined sampling cycle at a predetermined cycle. In the first step S1 of the tempo discriminating routine, the tempo discriminating unit 30 takes in the integral value waveform having a time length corresponding to the internal buffer force predetermined sampling period Ts. Figure 4 shows an example of the integrated value waveform captured here.

[0031] In subsequent step S2, the tempo discrimination unit 30 extracts a feature related to the tempo of the integrated waveform that has been taken in. For example, the low-frequency component of a music playback signal is strongly influenced by the regular base rhythm contained in the music, and the irregular waveform of the low-frequency component is dulled in the integrated waveform, and the rule due to the base rhythm The typical waveform appears more clearly. Therefore, it is considered that the peak interval tp of the integrated value waveform, in other words, the interval tp between the maximum values, has a strong correlation with the music tempo. Therefore, a clue to discriminate the tempo can be obtained by obtaining the peak interval tp in the sampling period Ts as a feature of the integrated waveform. If the peak interval tp is not constant, the average value, median value, mode, etc. may be obtained as the peak interval tp.

In the subsequent step S3, the tempo discriminating unit 30 discriminates the tempo of the music by using the feature from which the integrated waveform force is also extracted. For example, the tempo can be determined by converting the peak interval tp to BPM (Beat Per Minute). Alternatively, the music tempo may be distinguished into a plurality of stages in advance, and the tempo may be determined according to which stage the peak interval tp belongs to. In the next step S4, the tempo discrimination unit 30 outputs the obtained pulse signal indicating the tempo to the game control unit 31 as a tempo signal, thereby ending the tempo discrimination processing routine. The game control unit 31 controls the tempo game in which the tempo discrimination result by the tempo discrimination unit 30 is reflected as described above. The tempo game is started by, for example, selecting and instructing the main menu tempo game displayed on the LCD 3 by the input button 6. In the tempo game of the present invention, the user presses the input button 6 in accordance with the tempo of the music during music playback, a tempo signal (hereinafter simply referred to as “tempo”) obtained by the input operation, and a tempo discrimination unit 30. Evaluation is based on the degree of coincidence with the tempo discriminated in, and the display on the LCD 3 changes according to the evaluation.

In the tempo game of this embodiment, a case where the tempo obtained by the input operation and the determined tempo match is regarded as a correct answer, and the number of correct answers as a degree of coincidence is counted. Depending on the number of correct answers, multiple tension levels of 0 force 6 are set! The tension level increases as the number of correct answers increases. A character A as shown in FIG. 5 is displayed on the LCD 3 during the tempo game. Character A is displayed in a state of drifting when the game is silent, and is displayed in a state of performing dance according to each tension level after starting music playback.

[0035] Hereinafter, the manner of dance of character A according to each tension level is referred to as a dance mode. For example, character A is in dance mode according to tension level 1 at tension level 1 and dance mode according to tension level 4 at tension level 4. The target number of correct answers is set between each tension level, and when the target number of correct answers is achieved, it can be upgraded to the next tension level. For example, if the target number of correct answers between tension level 0 and tension level 1 is set to 8, when the number of correct answers at the start of the game reaches 8, the level can be increased to tension level 1.

[0036] At the time of level-up, a level-up cut UC corresponding to the tension level is instantaneously displayed on the LCD 3 as an inserted image. In this embodiment, the level-up cut UC is displayed twice for 0.2 seconds, for example. The level-up cut UC of this embodiment is a character string as shown in FIG. 5, and a character string corresponding to the tension level that has been upgraded is prepared. The level up cut UC may be displayed as long as the displayed character string is visible.

[0037] In addition, the degree of coincidence in units of songs is also evaluated, and depending on the evaluation for the song at the end of the song Privilege cut TC is displayed. The privilege cut TC of this form is “smile”, and a privilege cut TC that expresses a different “smile” according to the evaluation is prepared. Hereinafter, the tempo game executed by the game control unit 31 will be specifically described.

First, various data shown in FIGS. 6 to 8 stored in the storage device 25 necessary for executing the tempo game will be described. FIG. 6 is a diagram showing an example of the character's dance mode information 50. In this embodiment, a plurality of characters A, B, C-... Are prepared as characters displayed on the LCD 3. The character displayed on the LCD 3 may be set by the user's selection, or set so that each character is associated with a predetermined condition, and when the condition is satisfied, the character corresponding to the condition is displayed. Anyway! Each tension level from 0 to 6 is associated with a dance mode as display image information of each character. For example, the dance mode for character A at tension level 3 is A3. It is desirable that the dance mode for each character is set to become flashy as the tension level increases, for example.

FIG. 7 shows level-up information 60 in which the target correct number MS and the level-up cut UC are associated with each of the tension levels 0 to 6. The level-up cut UC of this embodiment is a character string as described above, and is prepared according to the tension level that has been leveled up. In this mode, “Ya!”, “Woo!”, “Yeah!”, “Cool!”, “Hot!”, And “Fever!” Are set as level-up cuts UC1 to 6 corresponding to each tension level 1 to 6, respectively. ing. For example, the target number of correct answers for leveling up from tension level 1 to 2 is 8, and when leveling up, level-up cut UC2, that is, the character string “Woo!” Is displayed. The target number of correct answers to advance from level 2 to 3 is 16, and level up cut UC3, that is, the character string “Yeah!” Is displayed when level up.

FIG. 8 shows privilege information 70 in which information related to the privilege cut TC is stored. In this embodiment, as shown in FIG. 8, three types of privilege cuts TC1, 2, and 3 are associated with each other according to the game correct answer rate. The game accuracy rate will be described later. In this embodiment, the bonus cut TC is not displayed when the game accuracy rate is 0 to 9%. When the game accuracy rate is 10% to 25%, the privilege cut TC1 is displayed. When the game accuracy rate is 26 to 40%, the privilege cut TC2 is displayed. When the game accuracy rate is 41% or more, the privilege cut TC3 is displayed. Bonus cut TC1, 2, 3 The higher the game answer rate, the higher the level of “smile”, for example, from a smiley expression to a big smile!

FIG. 9 shows play information 80 indicating the play status during the game. It is created in the control unit 11 at the start of the game and updated according to the play situation. The play information 80 includes character information indicating the type of character displayed on the LCD 3, level information LI indicating the current tension level, correct answer number information SI, and game correct answer information GI. Correct answer information SI indicates the number of correct answers in the game, and is reset when the level is increased. The game accuracy rate is a value obtained by the formula “number of correct answers in one song Z number of input buttons 6 pressed in one song”, and the game accuracy rate information GI is composed of the numerator and denominator values of the formula. Is done. Game accuracy rate information GI is reset each time a song ends.

[0042] Hereinafter, the tempo game process executed by the game control unit 31 will be described. FIG. 10 is a flowchart showing a tempo game processing routine for one song. The tempo game process is performed in parallel with the tempo determination process described above. In this embodiment, an example will be described in which character A is set as character information and tension level 1 is set, that is, level information LI of play information 80 is set to 1. LCD3 displays character A in dance mode A1. First, the game control unit 31 determines in step S10 whether or not the song has ended. If the tempo signal is output from the tempo discriminating unit 30, the game control unit 31 proceeds to step S11 and captures the input signal from the input button 6 along with the capture of the tempo signal.

In the next step S 12, the tempo based on the input signal from the input button 6 is compared with the tempo based on the tempo signal output from the tempo determination unit 30 to determine whether or not they match. The determination of whether or not the force is the same can be made, for example, by comparing the pulse of the input signal from the input button 6 and the pulse of the tempo signal from the tempo determination unit 30 from the beginning of music playback, When it is within the predetermined range, it is determined as “correct” as a match, and when the deviation width exceeds the predetermined range, it is determined as “incorrect” as a mismatch.

[0044] After determining the match, the game control unit 31 proceeds to step S13 and updates each of the correct answer number information SI and the game correct answer information GI of the play information 80. If the answer is determined to be correct, add 1 to the number of correct answers indicated by the correct answer information SI, and add the correct answer rate information GI to the numerator and denominator. Add 1 for each. If it is determined that the answer is incorrect, the correct answer number information SI is not updated, and only 1 is stored in the denominator of the game correct answer rate information GI.

[0045] After the play information 80 is updated, the game control unit 31 proceeds to step S14 and performs a level-up process. The level up process will be described later. The game control unit 31 returns to step S10 after the level-up process, and repeats the above-described process until the music ends. If it is determined in step S10 that the song has ended, the process proceeds to step S15 and privilege processing is performed. In this embodiment, the end of the song is determined when the tempo signal is not detected for 2 seconds. Thus, the game control unit functions as an end determination unit. The privilege process will be described later. After the bonus process ends, the tempo game process for one song ends. When the reproduction of the next song is started, the tempo game process is resumed from step S10.

The level-up process will be described according to the flowchart shown in FIG. First, the game control unit 31 determines whether or not a level-up force is present in step S20. In this embodiment, since the target number of correct answers at tension level 2 is 8, if the number of correct answers indicated by correct number information SI is greater than or equal to ¾, it is determined that the level is up. If the number of correct answer information SI is less than 8, it is determined that the level is not up and the level up process is terminated. The current user's tension level can be obtained from the level information LI, and the target number of correct answers for level-up can be obtained by referring to the level-up information 60.

If it is determined that the level is up, the game control unit 31 updates the play information 80 in step S 21. At the time of this update, the correct answer number information SI is reset to 0, and the level information LI is updated to the next tension level (in this embodiment, tension level 2). Subsequently, the game control unit 31 displays a level-up cut UC corresponding to the tension level of the level information LI on the LCD 3 in step S22. In this form, the level up cut UC2 is displayed twice for 0.2 seconds. Level information Level upcut UC corresponding to the tension level of LI is specified by referring to level-up information 60.

Subsequently, proceeding to step S23, the game control unit 31 switches the dance mode of the character A to a dance mode corresponding to the tension level of the level information LI. In this mode, the dance mode of character A displayed on LC D3 is switched from A1 to A2. Level information Refer to Dance Mode Information 50 for the dance mode corresponding to the LI tension level. More specific. After switching the dance mode, the level-up process is terminated. When the level up process reaches tension level 6, loop control is performed after returning to tension level 1.

The privilege process will be described with reference to the flowchart shown in FIG. First, in step S30, the game control unit 31 calculates a game correct rate by referring to the numerator and denominator of the game correct rate information GI of the play information 80. Next, the process proceeds to step S31, and it is determined whether or not a privilege cut TC is displayed. When the game accuracy rate is 9% or less, it is determined that the bonus cut TC is not displayed. If the privilege cut TC is not displayed, the process proceeds to step S34. If the privilege cut TC is displayed, the process proceeds to step S32. In step S32, the game control unit 31 specifies a privilege cut TC associated with the game correct rate calculated with reference to the special information 70.

[0050] After specifying the privilege cut TC, the process proceeds to step S33, and the game control unit 31 displays the specified privilege power TC on the LCD 3. Furthermore, for example, by performing the control of moving the privilege cut TC up and down one dot at a time, the motion can be expressed in the smile expression of the privilege cut TC. Finally, in step S34, the game control unit 31 resets the game correct rate information GI of the play information 80. That is, the numerator and denominator of the game accuracy rate information GI are set to zero.

[0051] In step S22, step S23, and step S33 of the processing described above, the game control unit 31 functions as a display control unit 3 lb. In addition, step S12, step S13, step S20, step S21, step S30 and step S32 [actually, it functions as an evaluation unit 31a.

The present invention can be implemented in various forms without being limited to the above form.

For example, the tension level may be 7 levels or more, and the type of privilege cut TC is not limited to the type described above. Level up cut Sound effect may be output along with UC display. In this case, information regarding sound effects corresponding to each tension level may be stored in the level-up information 60. The number of input buttons as the operation input unit is not limited to one, and a plurality of input buttons may be provided. The determination of the end of a song is not limited to whether or not a tempo signal is output, but may be determined based on the presence or absence of an output signal based on an audio output signal. The determination may be made based on the presence or absence of the audio output signal itself. Furthermore, for example, the signal processing unit is not limited to a single integration circuit for low-frequency components, and two or more integration circuits are provided for low-frequency components, so that each passing frequency range is different. It is also possible to determine the tempo using the output signals of those integration circuit powers. The signal processing unit may be configured as a hardware device that combines circuit elements such as IC and LSI, or may be configured as a logical device that combines MPU and software. Each of the tempo discrimination unit and the game control unit may also be configured as a hardware device. The signal input unit is not limited to the line input terminal. For example, a device that receives a playback signal transmitted using radio such as FM radio waves and converts it into a music playback signal may be used as the signal input unit.
