The CPU 3 controls execution of various processes of the metronome program according to the touch operation on the operation unit 1. The ROM 4 stores various programs executed by or referred to by the CPU 3, various data, and the like. The RAM 5 is used as a working memory that temporarily stores various data generated when the CPU 3 executes a program.
In the HDD 6, a metronome program loaded by the CPU 3 is downloaded from a predetermined URL via the network interface 7 and stored.

FIG. 2 is a block diagram showing a configuration of an electronic metronome device constructed in an information terminal by installing a metronome program.
The electronic metronome device includes a touch panel device 10 as a display of an information terminal, and a touch operation detection unit 11 that detects a touch operation on the touch panel device 10. The touch operation detection unit 11 detects the type of touch operation such as tap, drag, pinch-in / pinch-out, and long press described above, and detects the operation position of the touch operation within the touch panel. The type of touch operation and the detection of the operation position are performed by an existing technique that detects the movement of a finger on the touch panel.

The touch operation detection unit 11 is connected to the song set information setting unit 45 and the metronome playback switch unit 13, and the touch operation detected by the touch operation detection unit 11 depends on the operation content, and the song set information setting unit 45, the metronome playback switch. The data is output to each of the units 13.
The song set information setting unit 45 sets a wallpaper used as a background image of the touch panel as song set information. The song set information includes images used as wallpaper, song set names corresponding to the wallpaper, and metronome information such as tempo information. The song set information setting unit 45 sets the correspondence of each information.
The song set information set by the song set information setting unit 45 is stored in the song set information storage unit 46. That is, a plurality of pieces of song set information together with metronome setting information such as tempo and time signature and wallpaper are stored together with the song set name.

A process for setting song set information including wallpaper as a metronome background screen by the song set information setting unit 45 will be described with reference to FIGS. As shown in FIG. 3, the display screen 30 forming the touch panel includes a dial display unit 30a, a beat indicator display unit 30b, and a circle display unit 30c from the lower position.
The wallpaper 40 (FIG. 4) is composed of an image that is substantially the same size as the display screen 30 (landscape image in the example of FIG. 4), and is used as a background image of the entire display screen 30 as shown in FIG. It has become.
A song set name display section 30x is displayed at the lowermost position of the display screen 30, and song set information can be set by touching the song set name display section 30x.

When the finger is slid in the left-right direction on the song set name display section 30x (drag), the stored song set information can be switched. By this switching operation, the tempo, time signature, etc. in the song set information are read, and the current metronome setting information is updated with those values.
When the song set name display section 30x is tapped with a finger, a song list screen 60 on which a song list as shown in FIG. 6 is displayed pops up, and the song set information is switched by selecting the displayed song set name. Can do. When the accessory icon 61 (i button) at the right end of each song set name is tapped, a metronome information setting screen (not shown) corresponding to the song set name is displayed and each setting value can be changed. it can.
You can also add new song set names to the song list and set metronome information values such as wallpaper, tempo values, and time signatures that correspond to the song set names.

On the setting screen (not shown), the capturing of the wallpaper 40 and the brightness of the wallpaper 40 are set. For example, when capturing a wallpaper, it is possible to use an arbitrary image as a wallpaper by selecting an image already stored in the information terminal or an image taken with a camera attached to the information terminal.
Further, by making it possible to set the brightness of the wallpaper 40, it is possible to adjust the degree of transparency with respect to a control group (such as the dial 31) on the operation screen described later. The lightness of the wallpaper 40 is a normal value (second lightness) when the display screen 30 of the touch panel is in a normal state and a strong beat timing value (first lightness when flashing according to a strong beat timing described later). (Brightness brighter than normal value) is set individually. Of course, the relationship between the brightness of the first brightness and the second brightness may be reversed.

The dial display section 30a displays a disk-shaped dial 31 for changing the tempo of the metronome. In the dial 31, numbers serving as tempo values are displayed at predetermined value intervals. A triangular tempo setting position mark 32 is displayed at a position inside the center of the dial 31, and a numerical value corresponding to the scale position of the dial 31 indicated by the tempo setting position mark 32 is set as a tempo value of the metronome.
A circular pendulum 33 that reciprocates on the circumference of the dial with the center of the dial as the center of the circular motion and the tempo setting position mark 32 as the center is displayed inside the dial 31. The pendulum 33 moves circularly with a period according to the set tempo value during the metronome sound generation process.
In addition, inside the dial 31, swing width marks 34 a and 34 b are displayed that indicate both end positions of the periodic motion of the pendulum 33 with square brackets.

The dial 31 rotates the dial by sliding (dragging) the finger on the dial 31 so that a scale corresponding to the rotation angle is displayed. As a result, the tempo corresponding to the rotation angle is set by changing the numerical value corresponding to the scale position of the dial 31 indicated by the tempo setting position mark 32 on the dial 31.
Further, the scale numbers displayed on the dial 31 are automatically displayed with larger increments as the tempo value increases. For example, in the example of FIG. 3, the value is “8” on the side where the tempo value is small, and “32” on the side where the tempo value is large. "" Is displayed in increments of "2".

  In the touch operation detection unit 11 described above, the type and operation position of the touch operation are detected. The operation position includes whether or not the operation is performed on the dial 31, a time signature 35, a tempo circle 36, and a rhythm circle, which will be described later. 37. Information such as whether the operation is inside or outside the speed slogan circle 38 is also detected.

When the touch operation detected by the touch operation detection unit 11 is a drag rotation on the dial 31, the tempo information setting unit in the song set information setting unit 45 sets the tempo of the metronome.
When the touch operation detected by the touch operation detection unit 11 is a tap on the dial 31, the metronome playback switch unit 13 starts playback of the metronome (starts sounding) or stops playback (stops sounding).

In the beat indicator display section 30b, the number of beats (four beats in the case of FIG. 3) is displayed by a plurality of circular beat marks 35 displaying beat numbers. The time signature 35 can display the strength of the beat. That is, in the case of strong beats, the circle surrounding the beat number is displayed large (time signature mark 35a corresponding to beat number 1), and in the case of weak beats, the circle surrounding the beat number is displayed smaller than the strong beat (beats The time signature 35b corresponding to the numbers 2, 3, and 4). When the metronome sound generation process is performed, the sound is generated at the timing of each beat. The sound that is pronounced differs between strong beat and weak beat (strong beat is higher), and no sound is produced in the case of mute beat.
In addition, a flash display 35c in which the outer portion of the time signature mark 35 is brightened is performed at the timing of sound generation. In the flash display 35c, the range within the radius corresponding to the elapsed time is brightened. That is, the radius of the flash display 35c gradually decreases as time elapses from the sound generation timing of a beat, and becomes the smallest immediately before the sound generation timing of the next beat. Therefore, since the area of the flash portion is gradually reduced, the timing of the next beat is easily understood.

In addition, the wallpaper 40 as the background of the display screen 30 increases the lightness at the strong beat timing, and gradually becomes darker as time elapses from the sound generation timing of the beat, and is the lightest brightness immediately before the sound generation timing of the next beat. Is set to be small. That is, the lightness of the wallpaper 40 at the beat timing is set to the first lightness (strong beat timing value), and the lightness of the wallpaper 40 immediately before the beat timing is set to the second lightness (normal value). As time elapses, the lightness gradually changes from the first lightness to the second lightness.
Therefore, the whole beat of the display screen 30 is flashed and brightened at the beat timing, thereby making it easy to understand the timing of the strong beat. Also, if the lightness of the wallpaper is always increased, it will hinder the visibility of the important metronome settings, so it is desirable to increase the lightness only during strong beats.

For a plurality of time signature marks, the time signature is increased or decreased by dragging in the left-right direction. Dragging to the right increases the time signature and dragging to the left decreases the time signature.
In addition, dragging the time signature mark 35 upward changes the mute beat to a weak beat and changes the weak beat to a strong beat, and dragging it downward causes the strong beat to a weak beat. Processing to change the beat of the beat to mute is performed.

Moreover, you may set a time signature by the touch operation by a tap in the beat indicator display part 30b. For example, by tapping the first beat with two fingers, tapping other beats with one finger, and periodically performing these taps, the time signature and tempo can be set simultaneously.
For example, when the time signature displayed in FIG. 3 is set, the first beat may be tapped periodically with two fingers and the second to fourth beats with one finger.

  The circle display section 30c displays a tempo circle 36 that displays the tempo value as a number, a rhythm circle 37 that displays a rhythm, and a speed slogan circle 38 that displays a speed slogan. The size and position of each circle can be freely set in the edit mode and are displayed at positions that do not overlap each other.

  In the tempo circle 36, a numerical value corresponding to the scale position of the dial 31 indicated by the tempo setting position mark 32 is displayed as a tempo value in a circle. Accordingly, when the dial position is rotated by dragging on the dial 31 (according to the rotation angle), the numerical value indicated by the tempo setting position mark 32 is also changed at the same time, and the tempo value in the tempo circle 36 is also changed accordingly. Change.

The numbers displayed on the tempo circle 36 can be changed by a touch operation on the tempo circle 36. For example, right dragging to “displayed tempo value + 1 number”, left dragging to “displayed tempo value−1 number”, and upward dragging “displayed tempo value × 2 number ( Double-speed) ”and“ Drawing Tempo Value ÷ Number of 2 (Half Speed) ”by dragging downward.
The tempo can be switched between double speed and 1/2 speed by dragging up and down, making it instant and easy when you want to practice a musical instrument (for example, practice a drum) at 1/2 to 2 times the tempo of the original song You can change the tempo setting.

Further, by long-pressing in the circle of the tempo circle 36, a numeric keypad input screen (not shown) is displayed below the circle display portion 30c of the display screen 30, and the numeric keypad is used to input a numeric value, whereby the tempo circle 36 is displayed. You can change the tempo value directly.
Furthermore, by periodically tapping within the circle of the tempo circle 36, a tempo (tap tempo) corresponding to the cycle can be set. Further, while setting the tempo by periodically tapping the tempo circle 36 with one finger, at the same time, by tapping only the first beat with another finger in the beat indicator display section 30b, the time signature and the tempo are set. May be set simultaneously.

  The rhythm circle 37 displays rhythms such as 4 minutes, 8 minutes, 16 minutes, and triple in a circle. The rhythm displayed on the rhythm circle 37 can be changed by a touch operation on the rhythm circle 37. For example, rhythm switching is performed by dragging left and right to display quarter notes, eighth notes, sixteenth notes, triplets, and the like in this order.

  The speed slogan circle 38 displays a speed slogan in a circle, and by dragging left and right (touch operation) to the speed slogan circle 38, Largamente / Grave / Kargo / Lento / Adagio / Larghetto / Agadietto / Andante / Andantino / Maestoso / Moderato The speed motto is switched by displaying / Allegetto / Animato / Allegro / Vivace / Presto / Vivacissimo / Presto / Vivacissimo / Prestissimo in this order.

  Further, in the editing mode by long pressing outside the dial 31 described above, the positions of the tempo circle 36, the rhythm circle 37, and the speed slogan circle 38 on the circle display unit 30c can be moved, and the display can be enlarged or reduced. When moving each circle position or enlarging or reducing the circle display, move the circle position by dragging each circle, and change the circle display by changing the touch distance of two fingers (pinch in / pinch out). Can be scaled. In addition, when such movement processing or enlargement / reduction processing is performed, layout processing for each circle is automatically performed so that all the circles fit within the circle display unit 30c without overlapping with other circles.

  The sound generation unit 17 generates sound information at the time of metronome playback from information related to the tempo setting stored in the song set information storage unit 46. The sound information generated by the sound generation unit 17 is generated by the sound output device 25 via the sound reproduction unit 24.

Further, based on the sound information generated by the sound generator 17 (including tempo setting information and dial image information), the wallpaper 40 of the display screen 30 is flash-displayed at the strong beat timing in the wallpaper image generator 47. Thus, an image whose brightness changes is created and displayed on the touch panel via the display device 19.
By displaying the operation screen for setting the metronome displayed on the dial display unit 30a, the beat indicator display unit 30b, and the circle display unit 30c (control group of dial 31, various circles, etc.) in a translucent manner, the wallpaper 40 is displayed. Easy to see.

Next, the sound generation process in the electronic metronome apparatus described above will be described with reference to the flowchart of FIG.
First, a touch operation on the touch panel of the metronome device is detected (step 51).
Next, it is detected whether or not the detected touch operation is dragging of a song set (step 72).
When the song set is dragged, the song set is switched (step 66), and the song set is drawn on the touch panel (step 78).
If the song set is not dragged in step 72, it is detected whether the touch operation is a tap of the song set (step 73).

If the touch operation is a song set tap in step 73, it is determined whether or not new information is to be added (step 74).
If new information is to be added, song set information is input (step 75), the song set is added to the song list (step 76), and the song list is drawn by displaying the song list or selecting the song set (step 77). (Step 78).
If no new information is added, song set drawing is performed (step 78) by displaying a song list or selecting a song set (step 77).
The processing related to the song set drawing (step 78) will be described later.

If the touch operation is not a song set tap in step 73, it is detected whether the touch operation is a tap on the dial 31 (step 68).
If the touch operation is a tap on the dial 31, it is determined whether or not the metronome sound generation process is being performed (step 69).
If playback is in progress, playback is stopped (step 70). If playback is not in progress, playback is started (step 71).
If the touch operation is not a tap on the dial 31, a song set is drawn on the touch panel (step 78).

In the process of drawing the song set, it is determined whether or not the metronome sounding process is being performed (reproduction) (step 81). If not, the process returns to step 51.
If playback is in progress, the sound of the metronome is played (step 82), and the wallpaper is drawn by changing the brightness of the wallpaper (maximum brightness at the strong beat timing and gradually lowering the brightness) (step 79). .
It is determined whether or not the application is terminated (step 84). If the application is not terminated, the process returns to step 51.

According to the electronic metronome device described above, the beat timing can be reported on the entire touch panel by increasing the brightness of the wallpaper (flash display), so that the visibility of the metronome setting operation and setting value display is not impaired. The beat timing can be easily understood.
Arbitrary wallpaper can be set as the background image of the touch panel, so it is possible to use wallpaper that suits the user's preference and music.
