The communication interface 109 is an interface connected to a communication network such as a USB, a LAN, the Internet, or a telephone line, or a MIDI network, and is connected to the external device 115. The score displaying device 100 can input score information from the external device 115 via the communication interface 109, and display the score on the display device 105 via the VRAM 110.

[0014] The CPU 102 loads a program stored in the SSD or HDD into the RAM 104 and executes the program loaded into the RAM 104 to control the entire musical score displaying apparatus 100. The SSD or HDD stores the musical score display program executed by the CPU 102, and musical score information including staff notation, musical symbols, and lyrics. The RAM 104 temporarily stores information used in the processing of the CPU 102.

[0015] The display device 105 is, for example, a liquid crystal display, and displays musical scores and the like.

[0016] The sound source unit 108 includes software as a sound source and a DSP for adding effects, and generates a sound signal for playing a musical score. The sound source unit 108 outputs a sound signal to a sound system 114 based on performance information such as the note number, tone color, step, gate time, and velocity corresponding to the musical score. The sound system 114 has a D / A converter, an amplifier, and a speaker, and can play a musical score based on the sound signal generated by the sound source unit 108.

[0017] 2 is a block diagram showing an example of the functional configuration of the score display device 100. The score display device 100 has a display control unit 201, a magnification ratio calculation unit 202, and an editing unit 203. The score display device 100 realizes the functions of the display control unit 201, the magnification ratio calculation unit 202, and the editing unit 203 by the CPU 102 executing a program.

[0018] Fig. 9 is a flowchart showing a score display method of the score displaying device 100. Figs. 3 to 5 are diagrams showing examples of scores displayed by the score displaying device 100. A display area 300 is the display area of ​​the display device 105. As shown in Fig. 3, a display control unit 201 inputs score information from an SSD, HDD, or the like, and performs control so that all or a part of a score (staff notation) including multiple bars is displayed in the display area 300 based on the score information.

[0019] The magnification ratio calculation unit 202 detects, for each measure, one measure, and musical symbols 402 and lyrics 403 above and / or below the measure, based on the musical score information, as shown in Fig. 4. Furthermore, for each measure, the magnification ratio calculation unit 202 detects an area 401 that surrounds the detected measure and the musical symbols 402 and lyrics 403 that belong to the detected measure.

[0020] In step S901, as shown in FIG. 3, the user double-tap an area 302 in the display area 300 with a finger 301, thereby specifying a position within the display area 300 to be enlarged.

[0021] In step S902, the enlargement ratio calculation unit 202 determines which of the areas 401 of the measures in the musical score the area 302 is included in.

[0022] In step S903, if the region 302 is located in an area where the regions 401 of multiple bars overlap, the magnification ratio calculation unit 202 proceeds to step S904, and if the region 302 is not located in an area where the regions 401 of multiple bars overlap, the magnification ratio calculation unit 202 proceeds to step S907.

[0023] In step S907, the magnification ratio calculation unit 202 determines the area 401 of one bar that includes the area 302 as the area 401 of the bar that is closest to the area 302, and proceeds to step S908.

[0024] In step S904, the enlargement ratio calculation unit 202 determines which musical symbol 402 or lyrics 403 is closest to the area 302, and the process proceeds to step S905.

[0025] In step S905, the magnification ratio calculation unit 202 determines which of the overlapping multiple measure areas 401 the musical symbol 402 or lyrics 403 closest to the area 302 belongs to, and proceeds to step S906.

[0026] In step S906, the enlargement ratio calculation unit 202 determines the area 401 of one measure to which the musical symbol 402 or lyrics 403 closest to the area 302 belongs as the area 401 of the measure closest to the area 302, and proceeds to step S908.

[0027] In step S908, the magnification ratio calculation unit 202 calculates a variable magnification ratio for enlarging and displaying the confirmed area 401 of one bar in the display area 300, based on the size of the area 401 of one bar confirmed in step S906 or S907 and the size of the display area 300.

[0028] When the position of the double tap in area 302 is specified, the display control unit 201 controls the display area 300 to enlarge and display the musical score of FIG. 3 at the enlargement ratio calculated by the enlargement ratio calculation unit 202 so that the area 401 of the confirmed one measure fits within the display area 300, as shown in FIG. 5.

[0029] Here, one measure area 401 is an area surrounding the one measure and musical symbols 402 and lyrics 403 above and / or below the one measure that belong to the one measure. Note that one measure area 401 may be an area that includes not only the measure, musical symbols 402, and lyrics 403, but also objects such as text that belong to the measure.

[0030] In the above, an example has been described in which the display control unit 201 performs an enlarged display of FIG. 5 when a double tap is performed in a state in which the width of the musical score is displayed so as to fill the width of the display area 300 as in FIG. 3, but the present invention is not limited to this. The display control unit 201 can perform an enlarged display of FIG. 5 when a double tap is performed in a state in which the musical score is displayed at a display magnification smaller than the display magnification of the enlarged display according to the magnification of FIG. 5. Furthermore, the display control unit 201 can perform an enlarged display of FIG. 5 when a double tap is performed in a state in which the musical score is displayed at a larger magnification than that of FIG. 5 (for example, when only one quarter note is displayed in the display area 300) due to a user operation or the like.

[0031] The score displaying device 100 is also applicable to a score that does not have lyrics 403. In this case, the area 401 of one measure is an area that surrounds the one measure and musical symbols 402 above and / or below the one measure that belong to the one measure.

[0032] The score display device 100 is also applicable to scores that do not have musical symbols 402 above or below the measures. In this case, the area 401 of one measure is an area that surrounds the one measure and the lyrics 403 that belong to the one measure.

[0033] The score display device 100 is also applicable to a score that does not have musical symbols 402 above or below a measure and lyrics 403. In this case, the area 401 of one measure is an area that surrounds the above-mentioned one measure.

[0034] A user can handwrite musical symbols into the enlarged bar region 401 of Fig. 5 by touching the touch panel 107. When a musical symbol is handwritten into the enlarged bar region 401 of Fig. 5, the editing unit 203 recognizes the handwritten musical symbol based on the handwritten input position, and adds the recognized musical symbol to the musical score information. The display control unit 201 controls the font of the recognized musical symbol to be displayed in the display region 300 based on the handwritten input position.

[0035] If the enlarged display is not executed when the user double-tap on the display area 300, cancellation of the enlarged display is specified. When cancellation of the enlarged display is specified by double-tapping, the display control unit 201 controls so that the musical score including multiple bars is displayed in the display area 300 so that the width of the musical score fills the width of the display area 300, as shown in Fig. 3. The display control unit 201 controls so that either the enlarged display or cancellation of the enlarged display is executed based on the enlargement ratio calculated by the enlargement ratio calculation unit 202.

[0036] 6 to 8 are diagrams showing other examples of scores displayed by the score displaying device 100. The display area 300 is the display area of ​​the display device 105. As shown in Fig. 6, the display control unit 201 inputs score information from an SSD, HDD, or the like, and performs control so that all or a part of a score (staff notation) including multiple bars is displayed in the display area 300 based on the score information.

[0037] 7, the magnification ratio calculation unit 202 detects, for each measure, one measure, and musical symbols 702 and lyrics 703 above and / or below the measure, based on the musical score information. Furthermore, for each measure, the magnification ratio calculation unit 202 detects an area 701 that surrounds the detected measure, and the musical symbols 702 and lyrics 703 that belong to the detected measure.

[0038] In step S901 of FIG. 9, as shown in FIG. 6, the user double-tap the area 602 in the display area 300 with the finger 601, thereby specifying a position in the display area 300 for enlargement.

[0039] In step S902, the enlargement ratio calculation unit 202 determines which of the areas 701 of the measures in the musical score the area 602 is included in.

[0040] In step S903, if the region 602 is located in an area where the regions 701 of multiple bars overlap, the magnification ratio calculation unit 202 proceeds to step S904, and if the region 602 is not located in an area where the regions 701 of multiple bars overlap, the magnification ratio calculation unit 202 proceeds to step S907.

[0041] In step S907, the magnification ratio calculation unit 202 determines the area 701 of one bar that includes the area 602 as the area 701 of the bar that is closest to the area 602, and proceeds to step S908.

[0042] In step S904, the enlargement ratio calculation unit 202 determines which musical symbol 702 or lyrics 703 is closest to the area 602, and the process proceeds to step S905.

[0043] In step S905, the magnification ratio calculation unit 202 determines which of the overlapping multiple measure areas 701 the musical symbol 702 or lyrics 703 closest to the area 602 belongs to, and proceeds to step S906.

[0044] In step S906, the magnification ratio calculation unit 202 determines the area 701 of one measure to which the musical symbol 702 or lyrics 703 closest to the area 602 belongs as the area 701 of the measure closest to the area 602, and proceeds to step S908.

[0045] In step S908, the magnification ratio calculation unit 202 calculates a variable magnification ratio for enlarging and displaying the confirmed area 701 of one bar in the display area 300, based on the size of the area 701 of one bar confirmed in step S906 or S907 and the size of the display area 300.

[0046] When the position of the double tap in area 602 is specified, the display control unit 201 controls the display area 300 to enlarge and display the musical score of FIG. 6 at the enlargement ratio calculated by the enlargement ratio calculation unit 202 so that the area 701 of the confirmed one measure fits within the display area 300, as shown in FIG. 8.

[0047] Here, one measure area 701 is an area surrounding the one measure and musical symbols 702 and lyrics 703 above and / or below the one measure that belong to the one measure. Note that one measure area 701 may be an area that includes not only the measure, musical symbols 702, and lyrics 703, but also objects that belong to the measure, such as text.

[0048] In the above, an example has been described in which the display control unit 201 performs an enlarged display of FIG. 8 when a double tap is performed in a state in which the width of the musical score is displayed so as to fill the width of the display area 300 as in FIG. 6, but the present invention is not limited to this. The display control unit 201 can perform an enlarged display of FIG. 8 when a double tap is performed in a state in which the musical score is displayed at a display magnification smaller than the display magnification of the enlarged display according to the magnification of FIG. 8. Furthermore, the display control unit 201 can perform an enlarged display of FIG. 8 when a double tap is performed in a state in which the musical score is displayed at a larger magnification than that of FIG. 8 (for example, when only one quarter note is displayed in the display area 300) due to a user operation or the like.

[0049] The score displaying device 100 can also be applied to a score that does not have lyrics 703. In this case, the area 701 of one measure is an area that surrounds the one measure and musical symbols 702 above and / or below the one measure that belong to the one measure.

[0050] The score display device 100 is also applicable to a score that does not have musical symbols 702 above or below a measure. In this case, the area 701 of one measure is an area that surrounds the one measure and lyrics 703 that belong to the one measure.

[0051] The score display device 100 is also applicable to a score that does not have the musical symbols 702 above or below the measures and the lyrics 703. In this case, the area 701 of one measure is an area that surrounds the above-mentioned one measure.

[0052] A user can handwrite-input musical symbols into the enlarged bar region 701 of Fig. 8 by touching the touch panel 107. When a musical symbol is handwritten-input into the enlarged bar region 701 of Fig. 8, the editing unit 203 recognizes the handwritten musical symbol based on the handwritten input position, and adds the recognized musical symbol to the musical score information. The display control unit 201 controls the display area 300 to display the font of the recognized musical symbol based on the handwritten input position.

[0053] If the enlarged display is not executed when the user double-tap on the display area 300, cancellation of the enlarged display is specified. When cancellation of the enlarged display is specified by double-tapping, the display control unit 201 controls so that the musical score including multiple bars is displayed in the display area 300 so that the width of the musical score fills the width of the display area 300, as shown in Fig. 6. The display control unit 201 controls so that either the enlarged display or cancellation of the enlarged display is executed based on the enlargement ratio calculated by the enlargement ratio calculation unit 202.

[0054] Next, the effect of this embodiment will be described. In Fig. 3 and Fig. 6, the display area 300 displays the entire musical score. Since the entire musical score is displayed relatively small, it is difficult for the user to input musical symbols on the musical score. Furthermore, when the musical score is displayed small, if the user handwrites musical symbols, the handwritten input musical symbols will also be small. In that case, the editing unit 203 will be more likely to erroneously recognize the handwritten input musical symbols, and the probability of inputting the correct musical symbols will be lowered.

[0055] In this embodiment, when the user double-tap the area 302 in FIG. 3, as shown in FIG. 5, the display control unit 201 controls to enlarge and display the detected one measure and the musical symbols 402 and lyrics 403 belonging to the detected one measure in the display area 300 at the enlargement ratio calculated by the enlargement ratio calculation unit 202. The display area 300 enlarges and displays the musical score in FIG. 3 so that the area 401 of one measure fits in the display area 300. Since the desired measure is displayed relatively large, the user can easily input musical symbols on the musical score. In addition, since the one measure is displayed large, when the user handwrites musical symbols, the handwritten input musical symbols are also large. In this case, the editing unit 203 is less likely to erroneously recognize the handwritten input musical symbols, and the probability of inputting the correct musical symbols is improved.

[0056] In step S908, the magnification ratio calculation unit 202 calculates a variable magnification ratio for enlarging and displaying the confirmed area 401 of one bar in the display area 300, based on the size of the area 401 of one bar confirmed in step S906 or S907 and the size of the display area 300.

[0057] If the magnification is fixed and not variable, the display control unit 201 enlarges and displays one measure at a fixed magnification. However, the size of the entire score displayed in the display area 300 of FIG. 3 is indefinite depending on the score. Therefore, when the display control unit 201 enlarges and displays one measure at a fixed magnification, only a part of the measure may be displayed, or the display size of the measure may be too small. In this case, it is troublesome for the user to manually change the magnification. This does not make it easy for the user to input musical symbols.

[0058] In this embodiment, the enlargement ratio calculation unit 202 calculates a variable enlargement ratio for enlarging and displaying the area 401 so that the area 401 fits within the display area 300. Since the area 401 is enlarged and displayed to fill the entire display area 300, the area 401 including one bar is enlarged and displayed to an appropriate size. This makes it easier for the user to input musical symbols.

[0059] Another possible method is for the display control unit 201 to enlarge and display an area centered on the position where the user double-tapped. However, it is difficult for the user to double-tap the center of a measure accurately. Since the display control unit 201 enlarges and displays an area centered on the double-tapped position, it is not always possible to enlarge and display an area including one measure. This does not make it easy for the user to input musical symbols.

[0060] According to this embodiment, the magnification ratio calculation unit 202 detects one measure that is closest to the position of the specified area 302 based on the musical score information, and the display control unit 201 enlarges and displays the area 401 that includes that one measure. This makes it easier for the user to input musical symbols.

[0061] Another method is to enlarge the musical score by pinching out. However, it is difficult for a user to enlarge and display the area 401 in the display area 300 at a desired magnification ratio with a single pinch out operation. In general, a user needs to repeat pinch out and pinch in operations multiple times until the area 401 is enlarged and displayed in the display area 300 at the desired magnification ratio.

[0062] In this embodiment, when the user simply performs a double tap operation, the display control unit 201 can enlarge and display the area 401 at a desired magnification ratio in the display area 300. The user can enlarge and display the area 401 at a desired magnification ratio with a simple operation.

[0063] In addition, in the above-mentioned Patent Document 1, the display destination area is enlarged and displayed in a part of the original area. Therefore, the display destination area is not displayed on the entire screen, but is displayed small in a part of the screen. Since the display area is limited, the display destination area is not large enough for the user to input musical symbols.

[0064] In this embodiment, the display control unit 201 can enlarge and display the area 401 in the display area 300 at the maximum magnification ratio within a range in which the area 401 fits within the entire display area 300. Since the display control unit 201 can enlarge and display the area 401 to the maximum extent, it becomes easier for the user to input musical symbols.

[0065] As described above, the display control unit 201 can enlarge and display the area 401 at an optimal magnification ratio, making it easier for the user to input notes. Furthermore, the user can input notes while grasping the musical symbols around the position where the user wants to input the note. Also, since the magnification ratio calculation unit 202 automatically calculates the magnification ratio, the user does not need to change the magnification ratio each time. Also, the display control unit 201 can enlarge and display the area 401 at an optimal magnification ratio with a single double tap operation.

[0066] This embodiment can be realized by a computer executing a program. In addition, a computer-readable recording medium on which the above-mentioned program is recorded and a computer program product such as the above-mentioned program can also be applied as this embodiment. As the recording medium, for example, a flexible disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a magnetic tape, a non-volatile memory card, a ROM, etc. can be used.

[0067] It should be noted that the above-mentioned embodiments are merely examples of the implementation of the present invention, and the technical scope of the present invention should not be interpreted as being limited by these. In other words, the present invention can be implemented in various forms without departing from its technical concept or main features. [Explanation of symbols]
