FIG. 3 shows a flow chart showing a music reproduction process executed by the karaoke device 2. The karaoke device 2 refers to the reservation table (S101) and determines whether or not there is reservation information to be played next (S102). When there is reservation information (S102: Yes), it is determined whether or not the music of the reservation information to be played next is the music to be converted (S103). The determination of the conversion target music is performed, for example, by referring to the music ID included in the reservation information to be reproduced with the table in which the music IDs of the conversion prohibited music are defined. If the music ID to be played is listed on the table, it is determined that it is not the music to be converted (S103: No), and if the music ID to be played is not listed on the table, it is determined to be the music to be converted (S103: No). S103: Yes).

Here, examples of the music posted on the table that defines the conversion prohibited music include the following music.
-Songs that contain lyrics in the background video information-Songs that are prohibited from displaying two lines of lyrics-Songs that are prohibited from changing the display size of lyrics-Songs that display lyrics in five or more lines at the same time- Music in which the simultaneous color change event is used In the present embodiment, such a music is not treated as a music to be converted, and the subsequent lyrics information conversion process (S104) is not executed. If the song is not a conversion target song, that is, it is a conversion prohibited song, the second layout, which will be described later, is not switched and is displayed only in the first layout that uses the display position of the accompanying information of the lyrics information before conversion. Will be.

On the other hand, for the music to be converted, the lyrics information conversion process (S104) is executed for the lyrics information. The lyrics information conversion process (S104) of the present embodiment is a process of converting the original lyrics information specified in 4 to 3 lines into two lines or the original lyrics information specified in two lines into one line. is there. At that time, by reducing the character size of the lyrics, the background image is not obstructed by the lyrics even on the large screen monitor 41, and it is possible to improve the visibility thereof.

Next, this lyrics information conversion process (S104) will be described. FIG. 4 (A) is an example showing the display progress of the lyrics information for the lyrics information before conversion, and FIG. 4 (B) shows the display progress of the lyrics information based on the new line information for the lyrics information after conversion. This is an example showing. FIG. 4A shows a display process of lyrics displayed based on the lyrics information before conversion. In the present embodiment, at the display position (display line) included in the accompanying information, any line of 1 to 4 can be assigned as the Y coordinate. The character information 1 to 7 included in the line information are displayed at the coordinates based on the display position of each incidental information associated with each character information according to the display start timing and the display end timing.

For example, with respect to the line information 4 described with reference to FIG. 2B, since the display position (X1, Y1 (first line)), the display start timing t1, and the display end timing t2 are defined by the accompanying information, t1 to It is displayed on the first line (line number 1) during the period of t2. FIG. 5 (A) is a diagram showing the screen of the monitor 41 displayed in the first layout using the lyrics information before conversion, and shows the state at t1 shown in FIG. 4 (A). There is. At t1, the character information 4 "Uuuuuuu" is displayed on the first line (line number 1), and the character information 5 "yeah yeah yeah yeah" is displayed on the second line (line number 2), and the third line. Character information 2 "Ahhhhhhh" is displayed in (line number 3), and character information 3 "good good good good" is displayed in the fourth line (line number 4). The color change position C is indicated in the character information 3 “Ii Ii Ii Ii”, which indicates the singing timing.

FIG. 5 (B) is a diagram showing a screen of the monitor 41 displayed in the second layout using the converted lyrics information, and is a state at t1 in FIG. 4 (B), that is, FIG. 5 (A). ) And the situation at the same time are shown. After conversion, the character information 4 on the first line before conversion and the character information 5 on the second line are combined, and the character information 4 + 5 "Uuuuuuuueeeeeeeeeee" is displayed on the new first line. .. Further, the character information 2 on the third line before conversion and the character information 3 on the fourth line are combined, and the character information 2 + 3 "Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh That is, after the conversion (combination), the display position (display line), the display start timing, and the display end timing defined in the incidental information related to the converted (combined) character information are changed and temporarily saved in the memory 27. Character information is displayed based on the temporarily saved information. At that time, since the width of the character information may become long and not displayed due to the combination of the character information, the lyrics information after conversion is displayed with a smaller character size than the lyrics information before conversion. These prevent the background video information from being hindered by the lyrics information.

Here, a program that executes music playback processing will be described. The music playback process is a performance program that executes performance processing that reproduces performance information and outputs accompaniment sounds, a lyrics display program that executes lyrics playback processing that displays lyrics based on lyrics information, and when scoring processing is specified. The scoring program that executes the scoring process that evaluates the singer's singing is executed synchronously. Here, since the lyrics display program and the scoring program are programs that display lyrics and auxiliary images on the monitor 41, they can also be called display programs that execute display processing. In the scoring process, the score as the singing evaluation result is displayed, but it is also possible to perform the singing evaluation in a form in which the score is not displayed. For example, this corresponds to the case where only the piano roll 41a is displayed and the score is not displayed. Therefore, the scoring process may be a singing evaluation process as a superordinate concept thereof, and a singing evaluation program for executing the singing evaluation process may be used.

In the karaoke device 2 before the lyrics information conversion process (S104) was implemented, it was not necessary for the lyrics display program and the scoring program to synchronize the output control to the monitor 41. The lyrics display program displayed the lyrics at the display position specified in the accompanying information of the lyrics information, and the scoring program displayed the auxiliary image at the display position specified by itself. On the other hand, at least one of the display position and size of the lyrics is changed in the karaoke device 2 after the lyrics information conversion process (S104) is implemented due to the version upgrade of the karaoke device 2 or the new model of the karaoke device 2. Will be displayed.

Therefore, when the converted lyrics information is used in the lyrics information conversion process (S104), the lyrics display program outputs to the scoring program that the lyrics are displayed using the converted lyrics information. Upon receiving this output, the scoring program displays the auxiliary video based on the singing evaluation at a display position (second layout) different from the initially specified display position (first layout). On the other hand, when the lyrics display program uses the lyrics using the lyrics information before conversion, the lyrics display program does not output any information to the scoring program, and the scoring program has the initially specified display position. Auxiliary video is displayed in (1st layout). In this way, in the karaoke device 2 of the present embodiment, by synchronizing the lyrics display program and the scoring program (auxiliary video display program), it is possible to display the auxiliary video in a form suitable for displaying the lyrics after conversion. ing.

The present embodiment shown in FIGS. 5 (A) and 5 (B) is a case where the scoring process is executed (S106: Yes), and relates to singing evaluation such as piano roll 41a and skill images 41b to 41d. Auxiliary video based on auxiliary information is displayed. Whether the display layout of FIG. 5 (A) or the display layout of FIG. 5 (B) is used is changed by the layout change process executed in the music generation process. Here, the piano roll 41a is a display for comparing the pitch of the model singing and the pitch of the user's singing, and the pitch is set to the vertical position and the passage of time is set to the horizontal position, respectively. It is displayed in the shape of a bar. Further, the technique images 41b to 41d are images based on the technique information in the user's singing, and show the number of times the technique has occurred. In this embodiment, three types (fist, hiccup, vibrato) are used as skill information.

In the first layout of FIG. 5A, the piano roll 41a is displayed above the monitor 41, and the technical images 41b to 41d are displayed directly above the piano roll 41a. Currently, many karaoke songs use background images using the original artist. FIGS. 5 (A) and 5 (B) are also such cases, and are examples of displaying images sung by the original artist. In the first layout of FIG. 5A, the piano roll 41a portion is applied to the artist's face portion, and the main portion of the background image is blocked. On the other hand, in the second layout of FIG. 5B, the piano roll 41a is positioned at the lower part of the screen so that the artist's face portion is displayed without being obstructed.

Further, in the second layout, the reduced lyrics are displayed directly above the piano roll 41a, and the technical images 41b to 41d are displayed directly below the piano roll 41a. As described above, since the piano roll 41a is formed in a flat shape directly above the piano roll 41a, by displaying the lyrics in the portion directly above the piano roll 41a, it is possible to display the lyrics without being interrupted by the piano roll 41a. There is. Further, by displaying the lyrics in close contact with the piano roll 41a, the user can confirm the lyrics with the piano roll 41a without moving the line of sight significantly.

As described above, in the present embodiment, the visibility of various information during singing can be improved by making it possible to change to the first layout shown in FIG. 5 (A) and the second layout shown in FIG. 5 (B). It is possible to plan. In particular, in the second layout shown in FIG. 5B, the main part of the background image such as the artist's face displayed at the upper part of the screen is hidden by the auxiliary images such as the piano roll 41a and the technical images 41b to 41d. It is possible to display without. Further, in this second layout, the lyrics that are reduced from the original first layout are displayed by using the lyrics information converted by the lyrics information conversion process (S104), and the piano roll 41a and the skill image are displayed. Auxiliary images such as 41b have a layout suitable for reduced lyrics.

As described above, in the present embodiment, the display position of the auxiliary image is changed according to the change of the display position and the size of the lyrics, but at least one of the display position of the lyrics and the size of the lyrics is changed. Along with this, the display position of the auxiliary image may be changed.

In the present embodiment, in the first layout of FIG. 5 (A) and the second layout of FIG. 5 (B), the sizes of the piano roll 41a and the technical images 41b to 41d are not changed, but the first layout. The size of at least one of the piano roll 41a and the technical images 41b to 41d may be changed between the second layout and the piano roll 41a. For example, in the second layout of FIG. 5 (B), it is conceivable that the piano roll 41a and the technical images 41b to 41d are displayed smaller than the first layout of FIG. 5 (A). Therefore, it is possible to change the size of the auxiliary image according to the change of at least one of the display position of the lyrics and the size of the lyrics.

Returning to the music reproduction process of FIG. 3, when the lyrics information conversion process (S104) is completed, the accompaniment information included in the karaoke information is started to be reproduced (S105). In the present embodiment, when the scoring process is performed (S106: Yes) and the display form of the lyrics is specified as the second layout for reducing and displaying the lyrics (S106: second layout), FIG. 5 (B). ), The display is performed in the second layout using the converted lyrics information (S108). On the other hand, in other cases, that is, when the scoring process is not specified (S106: No), or when the scoring process is specified but the first layout is specified (S107: first layout). , The first layout using the lyrics information before conversion shown in FIG. 5 (A) is displayed (S110). At the time of scoring processing, the piano roll 41a and the technical images 41b to 41d are displayed on the monitor 41, and when the scoring processing is not performed, the piano roll 41a and the technical images 41b to 41d are not displayed on the monitor 41.

As described above, in the present embodiment, the lyrics information before conversion is used to display 4 to 3 lines depending on the designated status of the lyrics size and the display status of the piano roll 41a and the technical images 41b to 41d by the scoring process. Alternatively, the display form is switched to a two-line display using the converted lyrics information. At that time, the layouts of the piano roll 41a and the technical images 41b to 41d are different according to the display form of the lyrics. It should be noted that the present invention is not limited to such an embodiment, and the display form of the lyrics using the converted lyrics information may be used under appropriate setting conditions in the karaoke device 2.

In the music reproduction process of the present embodiment, the designation of the scoring process (S105) and the determination of the lyrics display form (S106) are repeatedly executed during the reproduction of the music, and the lyrics display form can be changed according to the situation. It has become. It should be noted that at least one of the designation of the scoring process and the display form of the lyrics may be prohibited from being changed during music playback. When the reproduction of the music is completed (S109: Yes), the process returns to the beginning of the music reproduction process, and the reservation table check (S101) is executed for the next music.

The music reproduction processing of the present embodiment has been described above, but in the present embodiment, the first layout displayed using the original lyrics information included in the music information, the lyrics information converted by the lyrics information conversion processing. Is displayed and can be changed to the second layout. At that time, in the first layout and the second layout, the display position of the auxiliary image (piano roll 41a, skill image 41b, etc.) based on the auxiliary information related to the singing evaluation can be changed, so that the current environment of the karaoke device 2 can be changed. In particular, it is possible to display the monitor 41 in a display form suitable for an environment in which the size is increasing.

In the present embodiment, the piano roll 41a and the skill image 41b have been used as the auxiliary image, but the auxiliary image used in the karaoke device includes not only such a form but also auxiliary information related to musical instrument performance. It may be an auxiliary image based on it. Currently, some karaoke devices have a function of displaying a guitar chord in addition to displaying lyrics in order to assist the guitar playing. Even in such a karaoke device, it is preferable to optimize the auxiliary video such as the reduced display of lyrics and the guitar chord video as the monitor becomes larger. Therefore, as for the video based on the information about the musical instrument performance as the auxiliary video, the layout can be changed as in the case of the piano roll 41a and the skill video 41b of the present embodiment, so that the display mode is suitable for an environment in which the monitor becomes large. It becomes possible to.

Further, in the present embodiment, the lyrics information conversion process (S104) is executed before the music ID of the karaoke information is designated (reserved) and the playback is started in the karaoke device 2, but the lyrics information conversion process (S104) The main body performing S104) or its execution timing can be appropriately performed. For example, instead of being executed by the karaoke device 2, the main body may execute the server device 5 and deliver the converted lyrics information or the karaoke information including the converted lyrics information to the karaoke device 2. Good. Alternatively, the lyrics information conversion process (S104) may be started immediately after the music is designated (reserved) by the user in the karaoke device 2.

Further, in the present embodiment, the lyrics information converted by the lyrics information conversion process (S104) is not reused, but the converted lyrics information is stored in the karaoke device 2 and the song is selected again. It may be reused at the time. In that case, the lyrics information conversion process (S104) is not newly executed. Alternatively, the converted lyrics information may be transmitted to the server device 5. It is also possible to collect the lyrics information converted by the server device 5 and distribute it to another karaoke device 2.

Further, in the present embodiment, the first layout and the second layout are switched on condition that the scoring process is specified and the display form is specified.
