[0009] Hereinafter, the embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are subject to various limitations that are technically preferable for implementing the present invention. Therefore, the technical scope of the present invention is not limited to the following embodiments and illustrated examples.

[0010] [Configuration of electronic musical instrument 100] Fig. 1 is a block diagram showing the functional configuration of an electronic musical instrument 100 including a display device of the present invention. Fig. 2 is a diagram showing an example of the external configuration of the electronic musical instrument 100. 1 and 2, electronic musical instrument 100 is configured to include at least one processor such as a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a keyboard 14, an operation unit 15, a display unit 16, a sound system 17, a communication unit 18, and pedals 19, with each unit being connected by a bus 20. Electronic musical instrument 100 includes the components of a display device of the present invention.

[0011] The CPU 11 (control unit) reads out the programs and data stored in the ROM 12, and executes various processes using the RAM 13 as a work area, thereby centrally controlling each unit of the electronic musical instrument 100. For example, the CPU 11 causes the sound system 17 to output the sound of a musical instrument such as a piano based on the operation of the keys of the keyboard 14 and the operation (performance operation) of the pedals 19. The CPU 11 also causes the sound system 17 to play music based on audio data, which is an input signal input from an external device via the communication unit 18. Furthermore, as performance assistance, the CPU 11 causes the sound system 17 to output (play) a model performance of a song selected by operating the operation unit 15. Furthermore, in response to a metronome playback instruction issued by operating the operation unit 15, the CPU 11 causes the display unit 16 to display a metronome display. Furthermore, in response to a recording instruction issued by the operation unit 15, the CPU 11 records a user performance based on operation of the keys of the keyboard 14 and operation of the pedals 19, etc. (records (stores) the user's performance information in a recording buffer (not shown) of the RAM 13), and causes the sound system 17 to play back the recorded user performance in response to operation of the operation unit 15. Furthermore, the CPU 11 controls the display on the display unit 16 by executing a display control process, which will be described later, in cooperation with a program stored in the ROM 12 .

[0012] The ROM 12 stores programs and various data, etc. For example, a program for executing a display control process described later is stored in the ROM 12. The ROM 12 also stores a plurality of pieces of information that can be displayed on the display unit 16 and information on the display mode of the display unit 16 corresponding to each piece of information in association with each other. The RAM 13 provides a working memory space for the CPU 11 and temporarily stores data. The RAM 13 also serves as a recording buffer to store user performance information and to store setting information for various functions, including display settings for the display unit 16.

[0013] As shown in FIG. 2, the keyboard 14 is configured to include a plurality of keys (performance operators), and outputs information on pressed / released keys and strength information (velocity) to the CPU 11.

[0014] As shown in FIG. 2, the operation unit 15 includes various operation buttons and switches such as a power button 151, and outputs to the CPU 11 operation signals in response to user operations of the operation buttons and switches. The operation unit 15 may be configured to have a tap-type operator that detects the user's finger by a change in capacitance.

[0015] As shown in FIG. 2, the display unit 16 is configured with a plurality of light-emitting units 161 (e.g., LEDs (Light Emitting Diodes)) arranged in a row in the arrangement direction of the keyboard 14, and displays specified information by turning on or off each light-emitting unit 161 in accordance with instructions from the CPU 11. The display unit 16 may further include an LCD (Liquid Crystal Display) or the like.

[0016] The sound system 17 includes a sound source unit 171 , an audio circuit 172 , and a speaker 173 . The sound source unit 171 reads out waveform data (audio data) prestored in the ROM 12 or generates waveform data and outputs it to the audio circuit 172 in accordance with a control instruction from the CPU 11 . The audio circuit 172 D / A converts and amplifies the waveform data (audio data) output from the sound source unit 171, and the speaker 173 outputs the amplified analog sound. The speakers 173 are provided on the left and right of the electronic musical instrument 100 (not shown), and output an audio signal based on the left sound source of the audio data from the left speaker, and an audio signal based on the right sound source from the right speaker. If the audio data is monaural, the audio signals based on the audio data are output from the left and right speakers.

[0017] The communication unit 18 transmits and receives data to and from an external device, such as an external terminal, connected via a communication interface, such as a communication network, such as the Internet, Bluetooth (registered trademark), or a USB (Universal Serial Bus) cable.

[0018] The pedal 19 includes, for example, a damper pedal, and outputs information on the ON / OFF state and the depression amount of the pedal to the CPU 11.

[0019] [Operation of electronic musical instrument 100] Next, display control in the electronic musical instrument 100 will be described. The display unit 16 can display any one of a plurality of pieces of information classified into the following categories A to D by changing the display mode of the display unit 16 by turning on or off each of the plurality of light-emitting units 161. In other words, the display unit 16 displays any one piece of information out of the plurality of pieces of information, and does not simultaneously display two or more pieces of information out of the plurality of pieces of information. Group A (first information): Information related to the user's performance operation (information such as the strength (velocity) of key pressing (on the keyboard 14) during the user's performance, the degree to which the pedal 19 is pressed, and the volume of audio data input from an external device) Group B (second information): Performance support information (metronome display, key pressing strength (velocity) in model performance, playback position of recorded user performance, etc.) Group C (third information): information on the setting value when setting the function of the electronic musical instrument 100 (information on the currently set setting value), notification information of the occurrence of an exception (information on Wait / Error / Bluetooth connection / disconnection, etc.) Group D (fourth information): Notification information for turning on or off the power of the electronic musical instrument 100

[0020] FIG. 3 is a diagram showing an example of a display mode in the display unit 16 according to information indicating the strength of key pressing in a user's performance, information indicating the degree of pedal depression, and information indicating the strength of key pressing in a model performance. In FIG. 3 to FIG. 5, a hatched circle indicates that it is emitting light (lighting) at a predetermined light intensity weaker than a white circle. A white circle indicates that it is emitting light at the maximum light intensity. A black circle indicates that it is not emitting light (it is turned off). The display unit 16 of this embodiment is configured to light up or turn off in units (called light-emitting units) consisting of three adjacent light-emitting units 161. When lighting up, the center of the three light-emitting units 161 lights up at the maximum light intensity, and both sides of it light up at a predetermined light intensity weaker than the center. The three lit light-emitting units 161 are made to look like one connected light by passing them through a filter (not shown). In addition, by lighting the light-emitting units 161 on both sides at a light intensity weaker than the center, it is possible to provide a display that does not feel strange even when the adjacent light-emitting units are turned off or the light-emitting units at the ends are emitting light.

[0021] FIG. 3(a) shows an example of a display when, for example, a key is pressed with a strength of level 1, the lowest of seven levels, or the pedal 19 is pressed with a pressing degree of level 1. FIG. 3(b) shows an example of a display when a key is pressed with a strength of level 7 (the highest level) or the pedal 19 is pressed with a pressing degree of level 7. As shown in FIGS. 3(a) and 3(b), information indicating the strength of the key press and information indicating the pressing degree of the pedal 19 are expressed by the number of light-emitting parts 161 that light up from the left side. When the strength of the key press or the pressing degree of the pedal 19 is weak, only three light-emitting parts 161 (light-emitting units) on the left side are lit as shown in FIG. 3(a), and the remaining light-emitting parts 161 are turned off. As the strength of the key press or the pressing degree of the pedal becomes stronger, the number of lights increases toward the right, and when it reaches the highest level, all the light-emitting parts 161 are lit (lit up) as shown in FIG. 3(b).

[0022] Fig. 4 is a diagram showing an example of a metronome display mode on display unit 16. As shown in Fig. 4, the metronome display repeats a display in which the leftmost light unit and the rightmost light unit alternately light up at the set tempo.

[0023] Fig. 5 is a diagram showing an example of a display mode of the error information on the display unit 16. As shown in Fig. 5, the error information is displayed by repeatedly turning on and off every other light-emitting unit at predetermined time intervals (for example, 0.25 seconds).

[0024] As described above, the display unit 16 switches between displaying a plurality of different pieces of information in a plurality of different display modes (lighting / extinguishing the light-emitting unit 161). In some cases, as described in FIG. 3(a), a plurality of different pieces of information may be displayed in the same display mode. This may cause the user to become confused as to which information is currently being displayed on the display unit 16. It may also be the case that information necessary for the user is not displayed.

[0025] Therefore, in this embodiment, priorities are set in advance for the above-mentioned groups A to D, and the CPU 11 executes the display control process shown in Fig. 6 to control so that information in a group with a high priority is preferentially displayed. This allows the user to know which information is currently being displayed on the display unit 16. Also, it allows information necessary for the user to be displayed.

[0026] For example, the user has a need to preferentially display performance support information in group B, such as the metronome display and information on the strength of key pressing in a model performance, over information on the user's own performance operation in group A. Also, when the user is setting functions, information indicating which setting value in group C is currently set is more important to the user than information on the user's performance operation or performance support information. Also, when an exceptional state such as Wait, Error, or Bluetooth connection / disconnection occurs in electronic musical instrument 100, the user needs to immediately recognize the state. Also, during the start-up process when the power is turned on and during the power cut process, performance, performance support, settings, etc. cannot be performed, so it is necessary to notify the user of this state as a top priority. Therefore, in this embodiment, the display priority order is set as group D>group C>group B>group A, and the CPU 11 controls to display information of a group with a higher priority order with priority. Information in each group is exclusively controlled so that it is not displayed simultaneously based on the display setting by the user.

[0027] The display settings can be set, for example, by the user operating the operation unit 15 etc. The set information is stored in the RAM 13. For example, the display setting for group A can be set to any one of "auto", "velocity fixed", "pedal fixed", and "audio illumination fixed". In this embodiment, when the information for group A can be displayed, if "auto" is set, information indicating the strength (velocity) of key depression is displayed on the display unit 16. If "velocity fixed" is set, information indicating the strength (velocity) of key depression is displayed on the display unit 16. If "pedal fixed" is set, information indicating the degree to which the pedal 19 is depressed is displayed on the display unit 16. If "audio illumination fixed" is set, information indicating the volume of audio data input from an external device is displayed on the display unit 16.

[0028] Also, for example, the display setting for group B can be set to any one of "auto", "metronome fixed", and "velocity fixed". In this embodiment, when group B information can be displayed, if "auto" is set, the metronome display is displayed on the display unit 16 during playback of the metronome, and if the metronome is not being played and a model performance is being played, information indicating the velocity of the model performance is displayed on the display unit 16. If "metronome fixed" is set, the metronome display is displayed on the display unit 16 during playback of the metronome. If "velocity fixed" is set, information indicating the velocity of the model performance is displayed on the display unit 16 during playback of the model performance. In addition, in group B, regardless of the above display settings, the information indicating the playback position of the recorded user performance is given top priority, and while the recorded user performance is being played back, the information indicating the playback position of the recorded user performance is displayed on the display unit 16.

[0029] The display control process will be described below with reference to Fig. 6. The display control process is executed by the CPU 11 in cooperation with a program stored in the ROM 12 when the power button 151 of the electronic musical instrument 100 is pressed to turn on the power.

[0030] First, the CPU 11 causes the display unit 16 to display information notifying the power-on (step S1). Specifically, during startup following power-on, the CPU 11 controls the turning on / off of each of the multiple light-emitting elements 161 in the display unit 16, causing the multiple light-emitting elements 161 to display in a predetermined display mode corresponding to the information notifying the power-on, thereby causing the display unit 16 to display information notifying the power-on.

[0031] Next, the CPU 11 determines whether or not a long press of the power button 151 has been detected (step S2).

[0032] In step S2, when it is determined that a long press of the power button 151 has not been detected (step S2; NO), the CPU 11 determines whether or not an event has occurred that requires the information of group C to be displayed (step S4). Events for which group C information should be displayed are the occurrence of an exception or a function setting operation.

[0033] When it is determined that an event has occurred that requires the display of the information of group C (step S4; YES), the CPU 11 starts a display process of the information of group C (step S5), and returns to step S2. For example, when an exception occurs, CPU 11 controls the turning on / off of each of the multiple light-emitting units 161 in display unit 16 as a display process for information of group C, and causes the multiple light-emitting units 161 to display in a predetermined display mode corresponding to information notifying the occurred exception. For example, when an error occurs, CPU 11 causes light-emitting units 161 to display in the display mode shown in Fig. 5. This causes display unit 16 to display information notifying the occurred exception. For example, when a function setting operation is performed by the operation unit 15 or the keyboard 14, the CPU 11 controls the lighting / extinguishing of each of the light-emitting units 161 in the display unit 16 as a display process for information of group C, and causes the light-emitting units 161 to display in a predetermined display mode according to the setting value of the function currently being set. This causes the display unit 16 to display information on the setting value at the time of function setting. When an exception occurs and a function setting operation occurs at the same time, the CPU 11 causes the display unit 16 to display information on either one of the two, based on a predetermined priority order.

[0034] When it is determined that an event requiring the display of the information of group C has not occurred (step S4; NO), the CPU 11 determines whether or not an event requiring the display of the information of group B has occurred (step S6). Events for which group B information should be displayed are when the metronome starts playing, when the model performance starts playing, and when the recorded user performance starts playing.

[0035] When it is determined that an event has occurred that requires the display of the information of group B (step S6; YES), the CPU 11 determines whether or not the display process of the information of group C is in progress (step S7). When it is determined that the display processing of the information of group C is being performed (step S7; YES), the CPU 11 returns to step S2. When it is determined that the display processing of the information of group C is not in progress (step S7; NO), the CPU 11 starts the display processing of the information of group B (step S8).

[0036] 7 is a flowchart showing the flow of the display process of the information of group B. The display process of the information of group B is executed by the CPU 11 in cooperation with a program stored in the ROM 12.

[0037] First, the CPU 11 determines whether or not playback of the recorded user performance has started (step T101). The playback of the recorded user performance is started in response to the user operating a predetermined switch or the like on the operation unit 15 .

[0038] When it is determined that playback of the recorded user performance has started (step T101; YES), the CPU 11 starts a process of displaying information indicating the playback position of the recorded user performance (step T102), and returns to step S2 in FIG. For example, the CPU 11 controls the lighting / extinguishing of each of the light-emitting sections 161 in the display section 16 to display the light-emitting sections 161 in a predetermined display mode corresponding to the current playback position in the recorded user performance. This causes the display section 16 to display information indicating the playback position of the recorded user performance.

[0039] When it is determined that the playback of the recorded user performance has not started (step T101; NO), the CPU 11 proceeds to step T103.

[0040] In step T103, the CPU 11 determines whether or not the reproduction of the metronome has started (step T103). Playback of the metronome is started in response to the user operating a predetermined switch or the like on the operation unit 15.

[0041] When it is determined that the reproduction of the metronome has started (step T103; YES), the CPU 11 determines whether the display setting of group B is "auto" or not (step T104). If it is determined that the display setting for group B is "AUTO" (step T104; YES), the CPU 11 proceeds to step T106.

[0042] When it is determined that the display setting of group B is not "AUTO" (step T104; NO), the CPU 11 determines whether the display setting of group B is "METRONOME FIXED" (step T105). When it is determined that the display setting of group B is not "fixed to metronome" (step T105; NO), the CPU 11 returns to step S2 in FIG. When it is determined that the display setting of group B is "fixed to metronome" (step T105; YES), the CPU 11 proceeds to step T106.

[0043] In step T106, the CPU 11 determines whether or not the recorded user performance is being played back (step T106). That is, the CPU 11 determines whether or not information indicating the playback position of the user performance is being displayed on the display unit 16. When it is determined that the recorded user performance is being played back (step T106; YES), the CPU 11 returns to step S2 in FIG.

[0044] When it is determined that the recorded user performance is not being played back (step T106; NO), the CPU 11 starts a process of displaying the metronome (step T107), and returns to step S2 in FIG. For example, the CPU 11 controls the turning on / off of each of the multiple light-emitting elements 161 in the display unit 16 to cause the multiple light-emitting elements 161 to be displayed in a predetermined display mode (e.g., see FIG. 4) corresponding to the metronome (the tempo set for the metronome), thereby causing the display unit 16 to display a metronome display.

[0045] On the other hand, if it is determined that playback of a model performance has started (step T108; YES) rather than playback of a metronome, the CPU 11 determines whether the display setting for group B is "Auto" (step T109). The reproduction of the model performance is started in response to the user operating a predetermined switch on the operation unit 15.

[0046] When it is determined that the display setting of group B is “Auto” (step T109; YES), the CPU 11 determines whether or not the metronome is being played (step T110). That is, the CPU 11 determines whether or not the metronome is being displayed on the display unit 16. If it is determined that the metronome is being played back (step T110; YES), the CPU 11 returns to step S2 in FIG. If it is determined that the metronome is not being played back (step T110; NO), the CPU 11 proceeds to step T112.

[0047] When it is determined that the display setting of group B is not "auto" (step T109; NO), the CPU 11 determines whether the display setting of group B is "velocity fixed" (step T111). When it is determined that the display setting of group B is not "velocity fixed" (step T111; NO), the CPU 11 returns to step S2 in FIG. When it is determined that the display setting of group B is "velocity fixed" (step T111; YES), the CPU 11 proceeds to step T112.

[0048] In step T112, the CPU 11 determines whether or not the recorded user performance is being played back (step T112). That is, the CPU 11 determines whether or not information indicating the playback position of the user performance is being displayed on the display unit 16. When it is determined that the recorded user performance is being reproduced (step T112; YES), the CPU 11 returns to step S2 in FIG. When it is determined that the recorded user performance is not being played back (step T112; NO), the CPU 11 executes a process of displaying information indicating the strength (velocity) of key depression in the model performance (step T), and returns to step S2 in FIG. For example, the CPU 11 controls the lighting / extinguishing of each of the light-emitting sections 161 in the display section 16 to display the light-emitting sections 161 in a predetermined display mode (see, for example, FIGS. 3(a) and 3(b)) corresponding to the strength of key pressing in the model performance. This causes the display section 16 to display information indicating the strength of key pressing in the model performance.

[0049] Returning to FIG. 6, if it is determined in step S6 that an event requiring the display of information of group B has not occurred (step S6; NO), the CPU 11 determines whether or not an event requiring the display of information of group A has occurred (step S9). When it is determined that an event requiring the display of the information of group A has not occurred (step S9; NO), the CPU 11 returns to step S2. When it is determined that an event has occurred that requires the display of the information of group A (step S9; YES), the CPU 11 determines whether or not the information of group C is being displayed (step S10). When it is determined that the information of group C is being displayed (step S10; YES), the CPU 11 returns to step S2. When it is determined that the information of group C is not being displayed (step S7; NO), the CPU 11 determines whether or not the information of group B is being displayed (step S8). When it is determined that the information of group B is being displayed (step S11; YES), the CPU 11 returns to step S2. When it is determined that the information of group B is not being displayed (step S11; NO), the CPU 11 executes a display process of the information of group A (step S12), and returns to step S2.

[0050] 8 is a flowchart showing the flow of the display process of the information of group A. The display process of the information of group A is executed by the CPU 11 in cooperation with a program stored in the ROM 12.

[0051] First, the CPU 11 determines whether or not a key depression operation (playing operation) has been detected on the keyboard 14 (step T201). When it is determined that a key depression operation is detected on the keyboard 14 (step T201; YES), the CPU 11 determines whether the display setting for group A is "AUTO" (step T202). If it is determined that the display setting for group A is "AUTO" (step T202; YES), the CPU 11 proceeds to step T204. When it is determined that the display setting of group A is not "auto" (step T202; NO), CPU 11 determines whether or not the display setting of group A is "velocity fixed" (step T203). When it is determined that the display setting of group A is not "velocity fixed" (step T203; NO), the CPU 11 returns to step S2 in FIG. When it is determined that the display setting of group A is "velocity fixed" (step T203; YES), the CPU 11 proceeds to step T204.

[0052] In step T204, the CPU 11 executes a process for displaying information indicating the strength (velocity) of key depression in the user's performance (step T204), and the process returns to step S2 in FIG. For example, the CPU 11 controls the turning on / off of each of the multiple light-emitting elements 161 in the display unit 16 to display the multiple light-emitting elements 161 in a predetermined display mode (e.g., see Figures 3(a) and (b)) corresponding to the strength of the key presses on the keyboard 14, thereby causing the display unit 16 to display information indicating the strength of the key presses in the user's performance.

[0053] On the other hand, when it is determined that a key depression operation on the keyboard 14 has not been detected (step T201; NO), the CPU 11 determines whether or not an operation of the pedal 19 has been detected (step T205). When it is determined that the operation of the pedal 19 has been detected (step T205; YES), the CPU 11 determines whether the display setting for group A is "pedal fixed" (step T206). When it is determined that the display setting for group A is not "pedal fixed" (step T206; NO), the CPU 11 returns to step S2 in FIG. When it is determined that the display setting for group A is "pedal fixed" (step T206; YES), the CPU 11 executes a display process for information indicating the degree of depression of the pedal 19 (step T207), and returns to step S2 in FIG. For example, the CPU 11 controls the turning on / off of each of the multiple light-emitting elements 161 in the display unit 16 to cause the multiple light-emitting elements 161 to be displayed in a predetermined display mode (e.g., see Figures 3(a) and (b)) corresponding to the degree to which the pedal 19 is depressed, thereby causing information indicating the degree to which the pedal is depressed to be displayed on the display unit 16.

[0054] On the other hand, if it is determined that the operation of the pedal 19 has not been detected (step T205; NO), the CPU 11 determines whether or not audio data has been input from an external device via the communication section 18 (step T208). When it is determined that no audio data is being input from an external device via the communication unit 18 (step T208; NO), the CPU 11 returns to step S2 in FIG.

[0055] When it is determined that audio data has been input from an external device via the communication unit 18 (step T208; YES), the CPU 11 determines whether the display setting for group A is "fixed audio illumination" (step T209). When it is determined that the display setting of group A is not "fixed to audio illumination" (step T209; NO), the CPU 11 returns to step S2 in FIG. When it is determined that the display setting of group A is "fixed to audio illumination" (step T209; YES), the CPU 11 executes a display process of the volume of the input audio (step T210), and returns to step S2 in FIG.

[0056] In step T210, for example, the CPU 11 controls the turning on / off of each of the multiple light-emitting elements 161 in the display unit 16 to cause the multiple light-emitting elements 161 to be displayed in a predetermined display mode corresponding to the volume of the input audio data, thereby causing the display unit 16 to display information indicating the volume of the input audio.

[0057] Returning to step S2 in FIG. 6, if it is determined that a long press of the power button 151 has been detected (step S2; YES), the CPU 11 causes the display unit 16 to display a power-off notification (step S3), and ends the display control process. For example, the CPU 11 controls the turning on / off of each of the multiple light-emitting elements 161 in the display unit 16 to display the multiple light-emitting elements 161 in a predetermined display mode indicating that the power is being cut off, thereby causing notification information of the power being cut off to be displayed on the display unit 16, and when the power cut-off is completed, ends the display control process.

[0058] As described above, the CPU 11 of the electronic musical instrument 100, in accordance with the set priority order, causes the display unit 16 to display the second information that supports performance, which is included in the plurality of pieces of information, with priority over the first information that corresponds to a performance operation, which is included in the plurality of pieces of information. Therefore, the information required by the user can be displayed satisfactorily on the display device of the electronic musical instrument 100.

[0059] The display unit 16 has a plurality of light-emitting units 161 arranged in a first direction, and the CPU 11 controls each of the plurality of light-emitting units 16 to be turned on or off, causing the plurality of light-emitting units 161 to display information in a display mode corresponding to each piece of information. Therefore, the information necessary for the user can be displayed satisfactorily on the display unit 16 which can only display one piece of information.

[0060] The contents described in the above embodiment are preferred examples of the display device, electronic musical instrument, display control method, and program according to the present invention, and the present invention is not limited to these.

[0061] For example, in the above embodiment, the display device of the present invention is provided within the electronic musical instrument 100, but the display device of the present invention may be provided in a separate device connected to the electronic musical instrument 100. For example, the display device of the present invention may be provided in an information processing device (such as a PC (Personal Computer), a smartphone, or a tablet terminal) connected to the electronic musical instrument 100.

[0062] In the above embodiment, the display unit 16 includes a plurality of light-emitting units 161, and information is displayed by turning on / off each of the plurality of light-emitting units 161, but the display method of the display unit of the present invention is not limited to this. For example, a display method in which information is displayed on an LCD screen may be used. The number of light-emitting units 161 and the display mode of each piece of information by the light-emitting units 161 are merely examples, and are not limited to those described above.

[0063] The above-mentioned information groups A to D exemplified as information that can be displayed on the display unit 16 are merely examples and are not particularly limited. For example, the information that can be displayed on the display unit 16 may be one or more pieces of information among the exemplified pieces of information and other information that is not exemplified.

[0064] In the above embodiment, an example is disclosed in which a semiconductor memory such as a ROM is used as a computer-readable medium for the program according to the present invention, but the present invention is not limited to this example.
