Among the performances, fingering by fingering is a particularly difficult technique for beginners. For example, if you press the key of Doremifasolacid with your right hand,
Do is the thumb, Le is the index finger, Mi is the middle finger, and when the next key is pressed, the thumb passes under the index finger and the middle finger and presses the key. On the contrary, when pressing the key of Dosila Sofa Milled, after pressing the fa with the thumb, the middle finger crosses over the thumb and presses the Mi (also referred to as the finger passage). However, in the conventional performance display control device, it is not possible to display a complicated fingering such as a finger dip. An object of the present invention is to be able to display fingering that supports performance and improves performance technology faster.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, first to sixth embodiments of the performance display control device of the present invention will be described with an electronic musical instrument having a keyboard as an example. FIG. 1 is a system configuration diagram common to the first to fifth embodiments. The CPU 1 controls the entire electronic musical instrument and, as will be described later, a determination means for determining whether or not the musical sound data is a performance operation of a finger-nip, and a state of the finger-nip based on the result of the determination. The display control means is configured. Further, the CPU 1 has two built-in timers (timer 1 and timer 2) for issuing a timer interrupt at regular intervals. The keyboard 2 inputs data of its key number, velocity, and note length to the CPU 1 in response to the operation of key depression and key release. Although not shown in the figure, a display switch is provided near the keyboard 2.
The display switch will be described later.

The LED 3 is a light source provided below each key of the keyboard 2, and emits a corresponding key when turned on.
The decoder driver 4 decodes the key emission command and the key extinction command of the CPU 1, and turns on or off the corresponding LED 3. The ROM 5 stores programs executed by the CPU 1, initial data, and tone data for automatic performance.
The RAM 6 is provided with a tone data area for storing data input from the keyboard 2 by the CPU 1, and areas for temporarily storing data necessary for executing a program, such as registers and flags.

The sound source 7 sends and stops a musical tone signal based on a tone generation command and a mute command from the CPU 1. D /
The A converter 8 converts the tone signal from the sound source 7 from digital to analog. The AMP 9 performs signal processing such as filter processing and amplification processing on the tone signal from the D / A converter 8 and supplies it to the speaker 10.
The LCD 11 displays fingering during performance, as will be described later. The LCD driver 12 drives the LCD 11 based on the display data from the CPU 1.

FIG. 2 shows an LED 3 corresponding to each key on the keyboard 2.
FIG. 3 is a diagram showing the arrangement of and a segment for displaying a fingering on the LCD 12. As shown in the figure, the segment has an index indicating each finger of both hands, a finger number, and an arrow indicating the direction of the finger crawl. When a key is pressed, the corresponding key emits light, and the finger pressing the key and the segment of the finger number light up. The method of displaying the arrow through the finger will be described later.

Next, the operation of the first to sixth embodiments will be described. FIG. 3 is a main flow of the CPU 1. After a predetermined initialization process (step S1), a switch process (step S2), a key depression process (step S3),
Sound generation processing (step S4), right hand processing (step S)
5) Then, a loop process for repeating the left-hand process (step S6) is started. In this loop processing, the switch processing, the key depression processing, and the sound generation processing are common to the respective embodiments, and only the right-hand processing and the left-hand processing are different in each embodiment.

In the switch processing of step S2, as shown in FIG. 4, it is judged whether or not the display switch is on (step S7). If this switch is not on, the process returns to the main flow, but this switch is turned on. When it is on, the flag DF is inverted (step S8). And
It is determined whether DF is 1 (step S9), and when this flag is 1, initial right-hand processing (step S1).
0), initial left-hand processing (step S11). When DF is 0 in step S9, all the displays are turned off (step S12), and timers 1 and 2 are stopped (step S13). Then, the process returns to the main flow.

The initial right-hand process in step S10 is
As shown in FIG. 5, the right-hand head address of the musical sound data is set in the address register RAD (step S14),
The RAD data (event start time data) is set in the timer register RTIME (step S1).
5). Then, the timer 1 is started (step S
16). When the timer 1 starts, as shown in FIG. 6, the data of RTIME is decremented every time a timer interrupt is entered (step S17). After this, the process proceeds to the initial left-handed process of step S11 of FIG.

In the initial left-hand processing, as shown in FIG. 7, the left-hand head address of the musical sound data is set in the address register LAD (step S18), and the timer register LTIM is set.
The data of the LAD (event start time data) is set in E (step S19). Then, the timer 2 is started (step S20). When the timer 2 starts, as shown in FIG. 8, the LTIME data is decremented each time a timer interrupt is entered (step S21). After the initial left-hand process, the process returns to the main flow.

As shown in FIG. 9, the key-depression process in step S3 of the main flow sets the pointer register N to 0 (step S22), and performs the following loop process while incrementing N. It is determined whether or not the key with the key number N has changed (step S23), and when it has changed from off to on, the flag ON (N) is set to 1 (step S24). Flag O when changed from on to off
FF (N) is set to 1 (step S25). ON
After setting (N) or OFF (N), or when the key does not change in step S23, N is incremented (step S26). Then, it is determined whether N exceeds the number of keys (step S27). If N does not exceed the number of keys, the process proceeds to step S23 and the loop process up to step S27 is executed. When N exceeds the number of keys in step S27, the process returns to the main flow.

In the sounding process in step S4 of the main flow, as shown in FIG. 10, the pointer N is set to 0 (step S28), and the following loop process is performed while N is incremented. It is determined whether or not the flag ON (N) is 1 (step S29). When this flag is 1, N is transferred to the sound source 7 as a pitch and a sounding instruction is given (step S30). Next, ON (N) is reset to 0 (step S31). In step S29,
If ON (N) is not 1, flag OFF (N) is 1
It is determined whether or not (step S32). When this flag is 1, the sound source 7 is instructed to mute the pitch of N (step S33). Next, OFF (N)
Is reset to 0 (step S34). After resetting ON (N) or OFF (N), N is incremented (step S35), and it is determined whether N exceeds the number of keys (step S36). If N does not exceed the number of keys, the process proceeds to step S29 and the loop process up to step S36 is executed. When N exceeds the number of keys in step S36, the process returns to the main flow.

From the pitch data of the current event set in
The pitch difference data is calculated by subtracting the pitch data of the previous event set in BRNOTE. further,
From the finger data (finger number) of the current event that is set to RUNSI, 1 that is set to BRUNSI
Finger number difference data is calculated by subtracting the finger data (finger number) of the previous event. Next, the pitch difference data and the finger number difference data are multiplied, and the data is set in the register A (step S107). Then, it is determined whether or not the data of A is negative (step S108). The initial values of BRNOTE and BRUNSI are set to 0 by the initialization process of the main flow.

For example, the pitch data of BRNOTE is 53
In (E4; Mi), it is assumed that the BRUNSI finger data is 3 (middle finger), the RNOTE pitch data is 54 (F4; Fa), and the RUNSI finger data is 1 (thumb). In this case, the calculation in step S107 becomes (54−53) × (1-3) = − 2 <0, and the data of A becomes negative. Further, the pitch data of BRNOTE is 54 (F4; FA), the finger data of BRUNSI is 1 (thumb), and the pitch data of RNOTE is 5

(Step S231), all displays are turned off (step S232), and the process returns to the main flow.

Regarding left-handed processing in the fourth embodiment,
This will be described with reference to FIGS. 36 to 38. In FIG. 36,
It is determined whether or not LTIME has become 0, that is, whether or not the waiting time TIME (0) at the beginning of the song has elapsed (step S233). When LTIME becomes 0, the address register LAD is incremented (step S234), and the NOTE ON / OFF data of the LAD is set in the register LSTATUS (step S23).

43). In this case, the highlighted left thumb moves under the other finger, and the left arrow indicating the finger number and the direction of the finger is displayed.

When the finger number data of LUNSI is not 36, if the finger passage of the left thumb is being displayed, it is turned off (step S244). Next, this data is 37
It is determined whether or not (step S245). When this data is 37, the finger passing display of the index finger of the left hand is displayed (step S246). In this case, the state in which the highlighted forefinger of the left hand crosses over the thumb, the finger number, and the right arrow indicating the direction of the finger passage is displayed. L
When the finger number data of UNSI is not 37, if the finger diversion of the left index finger is being displayed, it is turned off (step S247). Next, it is determined whether or not this data is 38 (step S248). This data is 38
If it is, the display of the middle finger of the left hand is displayed (step S249). In this case, the state in which the highlighted middle finger of the left hand crosses over the thumb, the finger number, and the right arrow indicating the direction of the finger passage is displayed.

When the finger number data of LUNSI is not 38, if the finger passage of the left middle finger is being displayed, it is turned off (step S250). Next, this data is 39
It is determined whether or not (step S251). When this data is 39, the finger passing display of the left ring finger is displayed (step S252). In this case, the state in which the highlighted left ring finger crosses over the thumb, the finger number, and the right arrow indicating the direction of the finger passage is displayed. When the finger number data of LUNSI is not 39, if the finger passage of the left ring finger is being displayed, it is turned off (step S25).

When the data of TATUS is NOTE OFF, LN
The key corresponding to OTE is turned off (step S254).

When the LUNSI data is not within the range of 36 to 39, or after the key is turned off in step S254, LAD is incremented (step S255) in FIG. 38, and the LAD data is set to LTIM.
It is set to E (step S256). And LAD
Is determined to be END (step S25)
7). Also, in step S233 of FIG.
Even when ME is not 0, the process proceeds to step S257 and L
It is determined whether AD is END. LAD is END
If not, return to the main flow.

When LAD is END, a flag LENDF indicating the end of the left hand is set to 1 (step S2
58), the timer 2 is stopped (step S259).
Then, it is determined whether or not the flag RENDF indicating the end of the right hand is 1 (step S260), and this flag is 1
If not, return to the main flow. On the other hand, when this flag is 1, the flag DF is reset to 0 (step S261) and all the display is turned off (step S26).
2) Return to the main flow.

As described above, according to the fourth embodiment, the presence / absence of a finger swipe is determined based on the change of the pitch of the musical sound data and the change of the finger to be pressed, and the state where the finger is displaced for the finger swipe. The image, the finger number, and the direction of the finger passing are displayed by arrows. Therefore, it is possible to display fingering that supports the performance and improves the performance technique faster.

Next, the event processing of the fifth embodiment will be described. In some performances, like a staccato performance, a note is played with a length of about ½. In this case, there is a blank time in which no sound is generated from the mute time of the event data (musical sound data) of the last performance sound to the sound generation start time of the event data of the next performance sound. The feature of this embodiment is that the performance operation of the finger pen is displayed according to the length of the blank time.

FIG. 40 is a diagram showing the structure of event data in the fifth embodiment. Note ON event data includes note ON, pitch number, velocity, finger number,
It consists of step time and gate time data, and note off event data is note off,
It is composed of each data of pitch number and velocity (= 0). The step time is the time from the start of the generation of an arbitrary performance sound to the start time of the next performance sound.

FIG. 41 is a flow chart of event processing.
This event process is a flow corresponding to the right-hand process in the main flow of FIG. Each register used in this flow is prepared in the RAM 6 and is cleared by the initialization process of the main flow of FIG.

In FIG. 41, the set time (predetermined time) previously stored in the ROM 5 is read and set in the register VAL (step S263). In addition,
This set time is changed by the player's operation to change the RAM 6
It can also be stored in. After step 263, the following loop process is executed. The event data shown in FIG. 40 is read (step S264), the pitch number of the read event data is set in the register GNOTE (step S265), and the finger number of the read event data is set in the register GUNSI (step S26).
6).

Then, it is determined whether or not the read event data is note-on (step S267). When the note is ON, a calculation is performed by subtracting the gate time of the event data of the immediately preceding note ON set in the register BGATE from the step time of the event data of the immediately preceding note ON set in the register BSTEP. Find the time difference. That is, the time difference from the silence time of the immediately preceding performance sound to the sounding start time of the next performance sound is obtained. The calculated time difference is set in the register X (step S268). Then, the value of VAL and the value of X are compared (step S269). Since there is no immediately preceding event data at the beginning of the song, the idle time (waiting time) until the first note ON, that is, a value larger than the value of VAL is set in BSTEP.
Is set to 0.

At step 269, the value of X is VAL.
When the value is smaller than the value of, the time difference from the mute time of the immediately preceding performance sound to the sound generation start time of the next performance sound is short. In this case, since there is no time to move the hand to perform the performance operation, there is a possibility that the performance operation may be performed by a finger. Therefore, a value obtained by subtracting the value of the register BNOTE that backs up the pitch number of the immediately preceding event data from the value of GNOTE, and a value that is obtained by subtracting the value of the register BUNSI that backs up the finger number of the immediately preceding event data from the value of GUNSI. Is multiplied and the multiplication result is set in the register A (step S270). That is, the difference between the current pitch number and the immediately preceding pitch number is multiplied by the finger number difference and set to A.
Then, it is determined whether or not the value of A is a negative value (step S271).

When the value of A is a negative value, the changing direction of the key pressing position is opposite to the changing direction of the key pressing finger.
It becomes the operation operation of the finger. Therefore, the direction of the finger passage is determined depending on whether the value obtained by subtracting the value of BNOTE from the value of GNOTE is a positive value (step S27).
2). If this value is a positive value, it means that the current pitch is higher than the previous pitch (to the right), so the right arrow is turned on (step S273). If this value is a negative value, it means that the current pitch is lower than the previous pitch (to the left), so the left arrow is turned on (step S274).

After lighting the arrow, the value of GNOTE is changed to B.
Set to NOTE and set the value of GUNSI to BU
Set to NSI and perform backup (step S2)
75). Furthermore, the step time and gate time of the current note-on event data can be set to BSTEP and BG.
Set to ATE (step S276). Then, the process proceeds to step 264 and the loop process is repeated.

At step 269, the value of X is VAL.
If it is equal to or more than the value of, the time difference from the mute time of the immediately preceding performance sound to the sounding start time of the next performance sound is not so short. In this case, since there is enough time to move the hand and perform the performance operation, the performance operation of the finger-nip is not displayed. Therefore, the value of GNOTE is set to BNOTE, and the value of GUNSI is set to BUNSI to perform backup (step S277). Further, the step time and gate time of the current note-on event data are set in BSTEP and BGATE (step S278). Next, if the arrow is turned on, the arrow is turned off (step S27).
9). Then, the process proceeds to step 264 and the loop process is repeated.

In step 271, when the value of A is a positive value, it means that the operation is not a finger-pulling operation. Therefore, backup is performed in steps 277 and 278, and the arrow is extinguished in step 279. Then, the process proceeds to step 264 and the loop process is repeated. In step 267, if the event data is not note-on, step 2
At 79, the arrow is turned off. And step 264
And the loop process is repeated.

FIG. 42 shows a specific example of the fifth embodiment.
An example of a right-handed performance is shown. FIG. 42 (1) shows a musical score of a note to be played, in which quarter notes are played at a tempo of 120 notes per minute. 42 (2) shows the event data of this musical score, which has the data format shown in FIG. The finger numbers in FIG. 42 (2) are 21, 2
Reference numerals 2 and 23 represent a thumb, an index finger, and a middle finger, respectively. Since quarter notes are played at a tempo of 120 notes per minute, each note-on event data E1, E3, E5,
The step times of E7 are all 0.5 seconds. In this case, the set time, that is, the value of VAL is 0.1
8 seconds.

Since the event data E1 is the event data of the first note ON of the music, X> VAL in step 269. Therefore, in step 277, the pitch number C3 is set in BNOTE, and BU
The finger number 21 is set in the NSI. Further, in step 278, BSTEP is set to 0.5, and BST
0.3 is set to GATE. Since the next event data E2 is note-off, the process proceeds to step 267, step 279, and step 264. Therefore, instead of performing a finger operation, a normal performance is displayed in which the C3 (do) key is pressed with the thumb.

In the case of the next event data E3, since the note is ON, the value of X is calculated in step 268. X = BSTEP (0.5) -BGATE (0.
3), it is determined that X> VAL in step 269, and the process proceeds to step 277. And BNO
The pitch number D3 is set in TE, and the finger number 22 is set in BUNSI. Further, in step 278, BSTEP is set to 0.5 and BGATE is set to 0.3. Since the next event data E4 is note-off, step 267 and step 27
9, the process proceeds to step 264. Therefore, instead of the operation of playing through the finger, a normal performance is displayed in which the D3 (re) key is pressed with the index finger.

In the case of the next event data E5, since the note is ON, the value of X is calculated in step 268. X = BSTEP (0.5) -BGATE (0.
3), it is determined that X> VAL in step 269, and the process proceeds to step 277. And BNO
The pitch number E3 is set in TE, and the finger number 23 is set in BUNSI. Further, in step 278, BSTEP is set to 0.5 and BGATE is set to 0.35. The next event data E6 is
Since the note is off, step 267 and step 2
79, and the process proceeds to step 264. Therefore, instead of performing a finger-hitting operation, a normal performance is displayed in which the E3 (Mi) key is pressed with the middle finger.

In the case of the next event data E7, since the note is ON, the value of X is calculated in step 268. X = BSTEP (0.5) -BGATE (0.3
5) = 0.15, so in step 269, X
<VALID is determined, the process proceeds to step 270, and (F3
−E3) × (21-23) = − 2 = A is calculated, and A becomes a negative value (−2). Therefore, the process shifts to step 272, F3-E3 = 1> 0, and step 273
In, the right arrow, which is an indication of the performance operation of the finger passing, lights up. Then, in step 275, BNOTE
Pitch number F3 is set to, and BUNSI finger number 21
Is set. Further, in step 276, B
STEP is set to 0.5 and BGATE is set to 0.3. The next event data E8 is the note OF
Since it is F, the processing shifts to step 267, step 279, and step 264. Therefore, in the case of this event data E7, the thumb is passed under the index finger and the middle finger to display the performance operation of the finger passage for pressing the key of F3.

As described above, according to the fifth embodiment,
When the time difference between the mute time of the musical tone data relating to the immediately preceding musical tone and the sound generation start time of the musical tone data relating to the next musical tone is within a predetermined time, the CPU 1 passes through the musical tone data of the next musical tone. If the time difference exceeds a predetermined time, it is determined that the musical tone data of the next performance sound is not a finger-rolling performance operation. In this case, the CPU 1 calculates the time difference by subtracting the gate time from the step time of the immediately preceding tone data. Therefore, similarly to each of the above-described embodiments, it is possible to display fingering that supports the performance and improves the performance technique faster. Further, in the case of the fifth embodiment, the arrow passing through the finger is turned on only when the time from the mute time of the immediately preceding performance sound to the sounding start time of the next performance sound is shorter than a predetermined time, and unnecessary lighting is performed. Therefore, the player is not forced to perform an advanced performance operation.

In the fifth embodiment, in the case of the musical tone data including the clock time from the beginning of the music data, the immediately preceding musical tone data is not calculated by subtracting the gate time from the step time of the immediately preceding musical tone data. It is also possible to obtain the note-on time difference of the next musical sound data from the note-off time and to determine whether or not it is a finger swipe performance operation according to the time difference.

Next, a sixth embodiment will be described with reference to FIGS. FIG. 43 is a system configuration diagram in the sixth embodiment. In this figure, the same components as those in the system configuration diagram shown in FIG. 1 are represented by the same reference numerals, and the description thereof is omitted. As is clear from comparison with FIG. 1, a tempo setting switch 13, which is a tempo setting means, is newly added to FIG. The tempo setting switch 13 may be an UP / DOWN switch or a numeric key switch. The tempo value initially set by the UP / DOWN switch is increased or decreased to set the desired tempo value, or the ten key switch is used to preset the desired tempo value.

Next, the operation of the sixth embodiment will be described. The main flow of the CPU 1 is the same as that shown in FIG. The structure of event data is also shown in FIG.
It is the same as that shown in 0. That is, the note-on event data is composed of note-on, pitch number, velocity, finger number, step time, and gate time data, and the note-off event data is note off, pitch number, and velocity. It is composed of each data of (= 0). The step time indicates the time from the start of the generation of an arbitrary performance sound to the start time of the next performance sound.

FIG. 44 is a flow chart of the switch process in step S2 of the main flow shown in FIG. In this process, it is determined whether or not the display switch is turned on (step S280), and if the switch is not turned on, the process returns to the main flow, but when the switch is turned on, the flag DF is inverted (step S281). ).
Then, it is determined whether DF is 1 (step S2
82), if this flag is 1, initial right hand processing (step S283), initial left hand processing (step S28)
Execute 4). In step S282, DF is 0
If so, all displays are turned off (step S28
5), stop timers 1 and 2 (step S28)
6).

Initial left-hand processing in step S284,
Alternatively, after the timer is stopped in step S286, it is determined whether or not the tempo value has been changed by operating the tempo setting switch 13 (step S287). When the tempo value is changed, the changed tempo value is written in the register TEMP (step S288). If the tempo value has not been changed, the predetermined tempo value is written in TEMP (step S289). After step S288 or step S289, the cycle of the timer interrupt is set according to the tempo value written in TEMP (step S290). Then, the process returns to the main flow.

FIG. 45 is a flow chart of the initial right hand process in step S286 of FIG. First, the registers used in this flow will be described. Register RT

Next, it is determined whether the previous step time written in the register BSTEP is larger or smaller than a predetermined value (step S295). If the previous step time is smaller than the predetermined value, the musical tone data to be played next is short in sounding start time, so that it is determined that the operation is a finger swipe. In this case, the following equation (GNOTE-BNOTE) x (GUNSI-BUNS)
I) write the value obtained in () to register A (step S29)
6). That is, a value obtained by multiplying the value obtained by subtracting the pitch number played last time from the pitch number played this time by the value obtained by subtracting the finger number played last time from the finger number played this time is written in A.

Then, it is determined whether or not the value of A is negative (step S297). When the value of A is negative, the operation is a finger play. In this case, it is determined whether or not the value obtained by the following equation GNOTE-BNOTE is positive (step S2).
98). That is, it is determined whether or not the difference between the pitch number of the current performance and the pitch number of the previous performance is positive. If the difference is positive, it means that the finger has passed in the right direction, so the right arrow is turned on (step S299). On the other hand, if the difference is negative, it means that the finger has passed to the left, so the left arrow is turned on (step S300).

After the arrow is lit, the current pitch number written in GNOTE is written in BNOTE as the previous pitch number, and the finger number written in GUNSI is written in BUNSI (step S301). Also, the step time of RTIME is transferred to BSTEP to perform backup processing (step S302). Then, this flow ends.

If the value of the previous step time BSTEP is greater than or equal to the predetermined value in step S295, or
If the value of A is positive in step S297,
Since it is not a finger-pulling performance operation, the current pitch written in GNOTE is transferred to BNOTE, and the current fingering written in GUNSI is set to BUN
Transfer to SI (step S303). Also, RTIM
The step time of this time written in E is BSTE
Transfer to P (step S304). That is, pitch,
Back fingering and step time. Next, the lighted arrow is turned off (step S305), and this flow ends.

The initial left-hand process in step S284 of FIG. 44 is basically the same as the initial right-hand process of FIG. However, in the process of step S297 of FIG. 45, the finger-passing performance operation is performed when the value of A is negative, but in the initial left-hand process, the finger-passing performance operation is performed when the value of A is positive. And Since the processes of the other steps are basically the same, the flow of the initial left-hand process is omitted.

As described above, in the sixth embodiment,
Depending on the step time of the musical sound data relating to the immediately preceding musical sound, it is determined whether or not the musical sound data of the next musical sound is a musical performance of a finger-narrowing operation, and an arrow for fingering the finger is displayed.
In this case, when the step time of the previous musical sound data is smaller than the predetermined value, it is determined that the musical sound data of the current musical sound is a finger-stroke performance operation, and the step time of the previous musical sound data is equal to or more than the predetermined value. In some cases, it is determined that the musical tone data of the performance sound of this time is not a performance operation of a finger.

Secondly, the calculation based on the change in the pitch of the key related to the key depression and the change in the finger related to the key depression is performed,
Based on the calculation result, it is determined whether or not the operation is a finger-stroke performance operation. Thirdly, if the time difference from the mute time of the musical sound data relating to the immediately preceding playing sound to the sounding start time of the musical sound data relating to the next playing sound is within a predetermined time, the musical sound data of the next playing sound is indicated. If the time difference exceeds the predetermined time, it is determined that the musical tone data of the next performance sound is not the finger-stroke performance operation. This time difference is calculated by subtracting the gate time from the step time of the musical sound data.

As a fourth embodiment of the procedure A, it is determined whether or not the musical tone data of the next musical performance sound is a finger-rolling musical performance operation according to the step time of the musical sound data relating to the immediately preceding musical sound. In this case, if the value obtained by dividing the tempo data of the piece of music to be played by the step time is larger than the predetermined value, it is determined that the musical tone data of the next performance sound is a finger-rolling performance operation, and the divided value is the predetermined value. If it is less than the value, it is determined that the musical tone data of the next performance sound is not a performance operation of a finger.

Further, in the above procedure B, when it is determined that the procedure A is a finger-clapping performance operation, the image of the finger under the finger, the finger number, and the direction of the finger-clapping may be displayed. . Furthermore, in the procedure B, when it is determined that the procedure A is a finger-clad performance operation, an image in which the finger is displaced due to the finger-clapping may be displayed.
