  FIG. 4 shows a lyrics display screen of a female part according to an embodiment of the present invention in a normal display state that is not enlarged. 3 is a screen displayed on the display 12 based on the first block of the lyrics character information shown in FIG. 3, and the lyrics character information is stored in a predetermined area 21 defined based on the coordinates included in the block data. Displayed in normal size (size that has not been enlarged). The predetermined area 21 is a range determined by the coordinates included in the block data and the size of the lyrics characters to be displayed, and is a portion indicated by a broken line (not actually displayed) in the figure. For reference, the figure shows the maximum display width H that can be displayed on the screen. The lyric character information is created so as to be located in a range not exceeding the maximum display width H.

  It is conceivable that the lyrics of the duet music displayed in this way are expanded to improve the visibility for users with weak vision such as the elderly. FIG. 5 shows a comparison of the size of lyrics characters between the normal display state and the enlarged display state according to the embodiment of the present invention. FIG. 5A shows the size of the normally displayed lyrics characters shown in FIG. 4, and FIG. 5B shows the size of the lyrics characters when enlarged. Further, the maximum display width H in the screen of the display 12 is shown in the meantime. When the lyrics characters are enlarged as shown in FIG. 5B, the maximum display width H in the screen is exceeded, and all the lyrics characters displayed in the normal display state cannot be displayed in one screen. It is possible. In such a case, it may be possible to divide and display the lyric character information included in one block on a plurality of screens. However, since the number of lyric characters displayed at one time is reduced, it is easy to sing. It will be damaged.

  The present invention has been made in view of the circumstances when enlarging such lyric characters, and in particular, paying attention to the presence of identification display information of male and female parts included in a duet song, and even when enlarged, lyric characters Lyric display processing is performed without impairing the ease of singing.

FIG. 6 shows a lyrics display screen when the lyrics characters according to the embodiment of the present invention are enlarged. In this embodiment, the gender part identification display information (heart symbol in the figure) is extracted from the lyric character information, and the lyric characters are enlarged and displayed in the predetermined area 21 in a state where the identification display information portion is packed. Yes. The extracted identification display information (heart mark) is displayed at the upper left of the predetermined area 21. As described above, in this embodiment, the identification display information included in the duet music is extracted and packed, so that the expansion range of other lyric character information is expanded. In this embodiment, the heart mark and the spade mark are used as the gender part identification display information. However, other character information may be assigned to the identification display information and used. Further, the identification display information may be different from music to music.

  Now, the music information reproduction process including the lyrics character enlargement process will be described with reference to the flowcharts shown in FIGS. FIG. 7 is a flowchart showing music information reproduction processing according to the embodiment of the invention. A user who operates the karaoke device designates a song to be sung using designation means such as the operation panel 10 in FIG. 1 or a remote control device connected to a network. The designation of the music can usually be performed in the form of reservation, and the reserved music is recorded with its identifier (for example, music number) in the reservation table in the RAM 15, and the identifier is sequentially stored from the reservation table. Reading and reproduction of the music information is executed.

  When the reproduction of the music information is started for the music specified from the operation panel 10 or the like, the music information stored in the hard disk 13 is first read in S101. In S102, playback is started based on the read music information. Here, the performance process S200 and the lyrics display process S300 are executed in parallel. In the performance processing, the performance information included in the read music information is sequentially sent to the audio processing unit 18 so that the performance of the music information is executed, whereby the music information is reproduced. Since this performance process is a process well known in the karaoke apparatus, description here is omitted. In the performance process, step values indicating the progress of performance information are sequentially output (S103). In the lyric display process S300, lyric characters are displayed in synchronization with the performance by displaying, changing colors, and erasing lyrics based on the step values. The reproduction of the music information is executed until the performance process S200 and the lyrics display process S300 are completed (S104).

  Now, details of the lyrics display process S300 will be described. FIG. 8 is a flowchart showing the lyrics display processing according to the embodiment of the present invention. The lyric display process is executed based on the lyric information in the music information as shown in FIG. 7 and the step value output with the performance process.

  For each block data included in the lyric information, block data processing loops of S301 to S310 are sequentially executed with S301 as the loop tip and S310 as the loop end. In S302, the step value output in the performance process is compared with each step (display step, erase step) included in the attribute data in the read block data. In S303 and S307, the process proceeds to each subsequent process based on this comparison.

  If it is determined that it is a display step (S304: Yes), it is determined whether or not enlargement designation of lyrics characters by the user is set. When enlargement designation of the lyric character is not set (S304: No), the lyric character information included in the block data is displayed in a display form as shown in FIG. On the other hand, when the enlargement designation of the lyric character is set (S304: Yes), as shown in FIG. 6, the lyric character is enlarged by excluding the identification display information outside the predetermined area 21. A display process S400 is executed.

FIG. 9 shows a flowchart of the enlarged display process according to the embodiment of the present invention. In this enlarged display process S400, first, it is detected whether or not there is part identification display information in the lyric character information in the block data to be displayed. If there is part identification display information (S401: Yes), the part identification information is extracted from the lyrics character information (S402), and the extracted part identification display information is displayed outside the predetermined area 21 (S403). The part identification display information may be displayed in the same size as that in the normal time or enlarged in the same manner as other lyrics character information.

  Next, the lyric character information from which the part identification display information is extracted is displayed in the predetermined area 21 in a larger size than the normal size (S404). At this time, the part in which the part identification display information is extracted is displayed in a packed manner so that the range that can be expanded is expanded. On the other hand, when there is no part identification display information in the lyric character information (S401: No), the lyric character information is enlarged and displayed in a predetermined area (S405).

  Returning to the flowchart of the lyrics display process of FIG. 8, if it is determined that it is an erasure step as a result of comparison with the step value (S307: Yes), the lyric character string of the block is erased. (S308). When the performance information has not been played (S309: No), the process returns from the loop end S310 to the loop end S301. By repeating the above processing until the performance information is finished (S309: Yes), the lyrics display synchronized with the performance processing is executed.

  As described above, the lyric display processing for displaying the lyric characters in the block unit has been described, in particular, the form that enables the expansion of the lyric characters in the duet song, but the present invention is limited to the lyric display in such a block unit. For example, the present invention can be applied to a form in which lyrics characters are scrolled and displayed. In this embodiment, the explanation is made on the assumption that the lyrics characters are enlarged and displayed, and the description of the display in the normal state (when not enlarged) is omitted.

  FIG. 10 shows a lyrics display screen for displaying lyrics in such scroll display. The state on the display 2 is shown in the figure. In the screen, a portion surrounded by a broken line (not actually displayed) indicates a scroll range 22 (corresponding to the “predetermined area” in the present invention), and the lyrics in the scroll range 22 are actually Characters are displayed. Here, lyric characters that are not displayed are also illustrated to facilitate understanding of the concept of scrolling.

  The lyrics display in the scroll can be realized with almost the same data configuration as the music data described in FIG. However, the coordinates in the block data and the erasing step are not necessary because of scrolling. The display step is defined as a step value indicating the timing for generating (displaying) the first character in the block data. The generation timing of this lyric character is set to be exactly the singing timing when positioned at the singing timing mark 23 displayed in the scrolled lyric character and lyric character screen.

  Here, the scroll range 22 is divided into areas of the lyric character generation stage A, the scroll stage B, and the erasure stage C, and description will be given as processing for each. FIG. 11 shows a flowchart of the lyric character generation process in the lyric character generation stage A, and FIG. 12 shows a flow chart showing the lyric character deletion process in the lyric character deletion stage C.

Regarding the lyric character generation stage A, first, in S401, lyric character information in the block data to be displayed next is read out. In S402, it is determined whether or not the lyric character information generated (started to display) as the lyric character is scrolled is part identification display information. When it is determined that the information is part identification display information (S402: Yes), the lyrics character information to be displayed next is read (S403). In S404, as shown in FIG. 10A, the lyric character information “A” read out in S403 is within the scroll range 22, and the part identification display information “heart mark” read out in S402. Scroll range 2
2 and displayed above the lyric character information “A” (S404).

  On the other hand, when the lyrics character information displayed next in S402 is not part identification information, display of the read lyrics character information is started in S405. In the scroll stage B, the lyric character information and the part identification display information displayed in S404 and S405 smoothly move (scroll) from the left side to the right side of the screen. FIG. 10B to FIG. 10D show the state of scrolling in time series.

  For the lyric character approaching the left end of the scroll range 22, that is, in the lyric character erasing step C, the lyric character erasing process shown in FIG. 12 is executed. In S501, it is confirmed whether or not the lyric character information to be erased is the last lyric character information in the lyric block. When it is determined that it is not the last lyric character information (S502: Yes), only the lyric character information is deleted, specifically, when scrolling out to the left end and accompanying part identification display information, The part identification display information is not erased and stopped at the left end of the scroll range 22 (S504).

  FIG. 10C and FIG. 10D show the state of this erasing stage C. In FIG. 10 (c), the lyric character “A” is scrolled out from the left end and erased from the scroll range 22, but after that, as shown in FIG. 10D, display begins with “A”. The displayed part identification display information “heart mark” remains at the left end. On the other hand, when it is confirmed that the lyric character information to be erased is the last lyric character information in the lyric block (S502: Yes), the lyric character information and the part identification information are erased. In this case, the lyrics character information is scrolled out to the left end, but the part identification information may be scrolled out or deleted at the display position.

  In this way, the part identification display information continues to be displayed until the corresponding lyric character information is erased, so that it is possible to make the user clearly recognize which part should be sung by the gender. .

  As described above, even when the lyrics characters are scrolled as in the present embodiment, even when the lyrics characters are enlarged by displaying the part identification information outside the scroll range 22 (the “predetermined area” in the present invention). Therefore, it is not necessary to reduce the number of characters displayed in the scroll range 22, and it is possible to provide an environment where the user can easily sing.

  Note that the present invention is not limited to these embodiments, and embodiments configured by appropriately combining the configurations of the respective embodiments also fall within the scope of the present invention.
