These results are output to the display control unit 200.

[Display controller]
The display control unit 200 controls various displays in the karaoke device 1. The display control unit 200 according to the present embodiment includes (1) guide melody image display control, (2) guide melody image display mode control, (3) displayed guide melody image fade-out control, and (4) last. Display control of the first guide melody image corresponding to the note is performed, and (5) fade-in control of the second guide melody image. Hereinafter, these controls will be described in detail. 4A to 4E show display screens of the display device 30. FIG. 4A is a display screen before the start of karaoke performance. 4B and 4C are display screens at the time when the karaoke performance has progressed to the middle of one phrase. FIG. 4D is a display screen when the karaoke performance of one phrase ends. FIG. 4E is a display screen when the karaoke performance of the next phrase is started. 4A to 4E, only the guide melody image is shown, but it is also possible to display the lyrics and the background image based on the lyrics telop data together with the guide melody image.

(1) Display control of guide melody image The display control unit 200, based on the guide melody data for guiding the karaoke singing of a music, displays a guide melody image indicating the time change of the pitch of the music for each note. Display it.

For example, when the music X is selected, the display control unit 200 reads the guide melody data of the music X from the storage unit 13 and divides it into phrases. Then, the display control unit 200 specifies the pitch, the sounding timing, and the sounding time from the guide melody data for each note included in each phrase, and the guide melody image Zn (n indicates the order of the note) corresponding to each note. Create a natural number). The display control unit 200 displays the guide melody image Z1 to the guide melody image Z4 (first guide melody image) of the notes included in the first phrase (first phrase) on the display device 30 when starting the karaoke performance. (See FIG. 4A). In addition, the display control unit 200 displays a cursor C that is displayed overlaid on the guide melody image and moves on the guide melody image as the karaoke performance progresses (see FIG. 4A). The guide melody image Z4 in FIG. 4A corresponds to the “first guide melody image corresponding to the last note included in the first phrase”. It should be noted that the phrase (second phrase) next to the first phrase includes four notes, and there is a melody image Z5 to a melody image Z8 (second guide melody image) corresponding to each of the four notes. To do. This melody image Z5 corresponds to "a second guide melody image corresponding to the first note included in the second phrase".

(2) Control of Display Mode of Guide Melody Image The display control unit 200 changes the display mode for each guide melody image according to the karaoke song.

When the karaoke performance of the piece of music X is started, the display control unit 200 moves the cursor C from the left side to the right side of the display screen as the karaoke performance progresses. The singer performs the karaoke singing by referring to the guide melody image while grasping the current playing position with the cursor C. And the song evaluation part 100 performs various evaluation according to a karaoke song.

For example, when the singing evaluation unit 100 outputs an evaluation result (presence/absence of deviation and deviation amount) regarding pitch and pitch deviation, the display control unit 200 determines the pitch for each guide melody image based on the result. And the note length are displayed using a song trajectory Tn (n is a natural number indicating the order of the song trajectory). For example, when the evaluation result that the note of the guide melody image Z1 has no pitch difference but the sound length has a gap (short) is input, the display control unit 200 slightly changes the guide melody image Z1. The short singing loci T1 are displayed in an overlapping manner (see FIG. 4B. The portion where the guide melody image and the singing loci overlap each other is indicated by diagonal lines). On the other hand, when the evaluation result indicating that the notes of the guide melody image Z2 are not different in tone length but the pitch is not input, the display control unit 200 indicates the singing trajectory T2 with respect to the guide melody image Z2. The display is shifted (see FIG. 4B). The degree to which the song trajectory is shifted is based on the shift amount obtained by the song evaluation unit 100.

Alternatively, when the evaluation result regarding the singing technique (the type of the singing technique and its timing) is output from the singing evaluation unit 100, the display control unit 200 indicates the singing technique for each guide melody image based on the result. Display the icon. For example, when the singing determination unit 100 detects a vibrato technique when singing a note corresponding to the guide melody image Z3, the display control unit 200 displays an icon V indicating vibrato at a position corresponding to the guide melody image Z3. (See FIG. 4B). Displaying a corresponding singing locus or displaying an icon of a singing technique for a certain guide melody image is an example of “changing the display mode (of the guide melody image)”.

(3) Fade-out control of displayed guide melody image The display control unit 200 fades out the guide melody image in order.

In order to display the guide melody images corresponding to the notes included in each phrase in order, it is necessary to fade out the guide melody images displayed before that in order as the karaoke performance progresses. Therefore, when the cursor C reaches a predetermined position of the guide melody image in the first phrase as the karaoke performance progresses (for example, the guide melody image corresponding to the last note in the first phrase). When the cursor C is located at the start position of Z4), the first displayed guide melody image Z1 is faded out (see FIG. 4C. The part indicated by the broken line corresponds to the faded out part). By completely fading out one guide melody image, the guide melody image (in this example, the guide melody image Z5) corresponding to the note included in the next phrase can be displayed.

Further, the display control unit 200 completes the fade-out of all the first guide melody images by the time the cursor C reaches the predetermined position of the guide melody image in the second phrase. For example, the display control unit 200 completes the fade-out of the guide melody image Z1 to the guide melody image Z4 included in the first phrase until the end position of the guide melody image Z7 is reached.

The position at which the fade-out is started and the position at which the fade-out is completed can be set arbitrarily. Further, this position is not only the start position/end position of a specific guide melody image, but also in the middle of the guide melody image (for example, a position of 85% of the entire guide melody image included in a phrase having a position where fade-out starts, Alternatively, it may be the position of 10% of the entire guide melody image included in the phrase that has a position for completing the fade-out). However, the fade-out of the first guide melody image (the guide melody image Z4 in the above example) corresponding to the last note included in the first phrase is performed after the song evaluation can be sufficiently confirmed.

(4) Display control of the first guide melody image corresponding to the last note The display control unit 200 displays the first guide melody image corresponding to the last note included in the first phrase displayed on the display screen. Is displayed with the display mode changed.

For example, when an evaluation result indicating that there is no difference in pitch or length of a note (last note) corresponding to the guide melody image Z4 is input, the display control unit 200 displays the singing locus T4 in the guide melody image. A predetermined icon is displayed at the end of the guide melody image Z4 while being superimposed on Z4 (see FIG. 4D. The portion where the guide melody image and the singing locus overlap is indicated by diagonal lines). The predetermined icon may be a graphic like the star icon shown in FIG. 4D, or may be a message based on the scoring result (for example, “Very good”, “Good”, “Bad”), It may be the score value itself (for example, "80 points"). Displaying a predetermined icon for a certain guide melody image is an example of “changing the display mode”.

(5) Fade-in control of second guide melody image Here, in the state of FIG. 4D, since the karaoke performance of the first phrase is all finished, it is necessary to display the guide melody image of the next phrase. On the other hand, if the screen of the next phrase is switched to as soon as the karaoke performance ends as in the conventional art, the singing evaluation (singing locus T4 or star icon) of the guide melody image Z4 as shown in FIG. 4D is sufficient. Can not be confirmed.

Therefore, the display control unit 200 displays the second guide melody image corresponding to the first note included in the phrase next to the phrase including the last note as the first guide melody image in the state in which the display mode is changed. Fade in to the same display screen while it is being displayed.

In this example, the display control unit 200 fades the guide melody image Z5 corresponding to the first note included in the next phrase on the same screen while the singing trajectory T4 and the star icon for the guide melody image Z4 are displayed. (See FIG. 4D. The part indicated by the alternate long and short dash line corresponds to the part that fades in). In this case, even when the guide melody image Z5 is completely displayed, the singing locus T4 and the star icon for the guide melody image Z4 can be confirmed (see FIG. 4E). In the example of FIG. 4E, the singing locus T3 and the vibrato icon V for the guide melody image Z3 can also be confirmed. On the other hand, the guide melody image Z2 is faded out as the karaoke performance progresses. Then, as the guide melody image Z2 fades out, the guide melody image Z6 next to the guide melody image Z5 can be faded in.

As described above, according to the karaoke device 1 of the present embodiment, the first guide melody image (guide melody image Z4) corresponding to the last note included in the first phrase displayed on the display screen is displayed. The display can be displayed in a changed state. Therefore, there is no problem that the screen is switched at the same time as the karaoke performance corresponding to the last note is finished and the singing evaluation for the guide melody image Z4 cannot be confirmed. Further, according to the karaoke device 1 according to the present embodiment, the second guide melody image (guide melody image Z5) corresponding to the first note included in the second phrase corresponding to the phrase next to the first phrase. Can be faded in to the same display screen while the first guide melody image is displayed. Therefore, the singer can easily understand the next guide melody (the guide melody corresponding to the guide melody image Z5) even when the evaluation result of the first guide melody image is displayed. .. That is, according to the karaoke device 1 of the present embodiment, when using the guide melody, both the singing evaluation for the last guide melody image displayed on one screen and the guide melody image to be referred to next are grasped. Can be made easier.

The display control unit 200 can start (or complete) the fade-in of the guide melody image Z5 before the display mode of the guide melody image Z4 changes (before the display mode changes and is displayed). Is. For example, as shown in FIG. 5, before the cursor C completely moves on the guide melody image Z4 (before the singing evaluation for the guide melody image Z4 is displayed), the display control unit 200 displays the guide melody image Z5. The display is started (or the guide melody image Z5 is completely displayed). Even in such a case, the guide melody image Z4 whose display mode has changed is displayed until the cursor C moves to the end position of the guide melody image Z7. Therefore, the singer can grasp the guide melody image Z5 to be referred to next, and can grasp the song evaluation for the guide melody image Z4.

Further, regardless of whether the timing of starting the fade-in of the guide melody image Z5 is before or after the display mode of the guide melody image Z4 is changed, at a certain point of time, the final phrase included in the first phrase is changed. A state in which the display mode of the first guide melody image (guide melody image Z4) corresponding to the note changes and a second guide melody image (guide melody image Z5) corresponding to the first note included in the second phrase. And are always displayed on the same display screen.

<Modification>
For example, in the above embodiment, when the playing time from the first note to the last note included in the second phrase is long, the cursor C moving on the guide melody image Z5 to the guide melody image Z8 corresponding to the note is long. Movement speed becomes slow. Therefore, as a result that the time for the cursor C to reach the position where the fade-out of the guide melody image included in the first phrase is completed (the end position of the guide melody image Z7) becomes long, the speed of the fade-out becomes extremely slow and the guide melody image It will be annoying to the singer who refers to the cursor or cursor.

Therefore, the display control unit 200 preferably measures the time from the start to the completion of the fade-out, and when the time exceeds the predetermined time, it is preferable to complete the fade-out of the first guide melody image in the predetermined time. It is possible to preset an arbitrary value for the predetermined time.

In addition, the display control unit 200 may advance the fade-in and the fade-out at a constant distance until the fade-out is completed. In this case, if the playing time from the first note to the last note in the first phrase is long (the fade-in speed is slow), or from the first note to the last note in the second phrase. If the playing time is short (when the moving speed of the cursor is high), the moving speed of the cursor C may exceed the speed of fade-in, and the cursor C may overtake the fade-in guide melody image.

Therefore, the display control unit 200 causes the cursor C to the second guide melody image corresponding to the first note included in the second phrase from the first guide melody image corresponding to the last note included in the first phrase. When it is determined that the position of the cursor C when the fade-in of the second guide melody image is completed exceeds the predetermined position of the second guide melody image when the cursor C moves to the second guide The fade-in of all the second guide melody images is completed before reaching a predetermined position on the melody image.

Specifically, the display control unit 200 obtains the time when the fade-in up to the guide melody image Z8 in the second phrase is completed when the cursor C is located on the guide melody image Z5 in the second phrase. When the display control unit 200 determines that the position of the cursor C at the obtained time advances ahead of the predetermined position, the display control unit 200 sets the speed of the fade-in so that the fade-in is completed before the cursor C reaches the predetermined position. Calculate and perform fade-in processing at the speed. The predetermined position is an arbitrary position in each phrase (for example, the position of 25% of the entire guide melody image included in a certain phrase) and can be set in advance.

The change in the display mode of the guide melody image is not limited to the example of the embodiment. For example, the case where the color of the guide melody image is changed according to the degree of pitch or tone length deviation is also included in the “change in display mode”.

The above embodiments are presented as examples and do not limit the scope of the invention. The above configurations can be appropriately combined and implemented, and various omissions, replacements, and changes can be made without departing from the scope of the invention. The above-described embodiments and modifications thereof are included in the scope of the invention and the scope of the invention, and are also included in the invention described in the claims and an equivalent range thereof.
