Description

  The present invention relates to a technique for displaying lyrics in different colors in synchronization with the performance of a song.

  As is well known, the karaoke apparatus displays the lyrics of the song on the display while synchronizing with the performance. This allows karaoke users to sing with poetry while watching the lyrics, even if they do not remember the lyrics. Furthermore, in general, the lyrics are displayed in different colors in synchronization with the performance so that the lyrics can be uttered more faithfully by the original music. Techniques for displaying lyrics while changing colors are disclosed in, for example, Japanese Patent Laid-Open Nos. 10-282971 and 2003-15668.

  That is, in a known communication karaoke apparatus, a central control unit including a CPU, a RAM, and a ROM controls the peripheral components to control the karaoke apparatus. The hard disk device stores karaoke data including accompaniment music data mainly composed of MIDI data and lyric rendering data that is the origin of generation of lyric images for a large number of songs. Also stored are moving image data for a long time in a predetermined format and script data defining a processing sequence of moving image data. Karaoke data and moving image data are supplied via a network interface or a storage medium such as a memory card at an appropriate communication opportunity with a karaoke host device (a karaoke provider's server).

  The karaoke device includes a user interface device that accepts a user's instruction input, extracts karaoke data of the user's requested song, and transfers accompaniment music data to a synthesizer to generate accompaniment music. Further, based on the lyric rendering data, a lyric character string in which a portion to be sung is changed in color in synchronization with the accompaniment music is generated. Lyrics rendering data is divided into appropriate measures for all lyrics characters into character strings, and information such as the display / erase order of the character strings (lyric rendering sequence) and the display position of the character strings, and display / erase of each character string Information such as timing and color change timing (single time instruction) for each character in the character string is described in association with the elapsed performance time of the song. When the central control unit starts playing the song, it generates a lyric image including the designated lyric character string at the designated timing based on the elapsed time of the song, and each character of the lyric character string is produced at the designated timing. Lyric images that change colors are sequentially generated, and bitmaps are sequentially developed in the video memory. Then, the contents of the video memory are displayed on the display.

Also, based on the script data, predetermined video data is sequentially transferred to the video controller in a predetermined order to decode the background image of the lyrics image, and the lyrics image is superimposed on the decoded video image, and the lyrics image is entered. Video is displayed on the display.

  In recent years, the number of people who download music data from the Internet or the like to a small portable music player has increased dramatically. It is inevitable that singing karaoke music will be desired in the future, as it is not enough to have a song with a general singing voice. Then, it is convenient if the lyrics of the song can be displayed on the display (display) of such a portable music player, and many users are expected. However, as a matter of course, since such a portable music player pursues portability, its display device is very small and can only display a character string of about two lines at most.

  On the other hand, karaoke users generally enjoy singing songs with poetry, but many karaoke users do not fully remember the lyrics. Therefore, it is necessary to display lyrics long enough before and after the part to be sung so that the lyrics can be understood. Moreover, it is desirable that the kanji has ruby so that it can be easily read in an instant.

  Therefore, an object of the present invention is to efficiently display lyric characters with ruby on a small display such as a portable music player.

  According to a fifth aspect of the invention, one lyric text line is displayed in the first line area of the display unit, and this lyric text one line is displayed in the second line area of the display unit. The process of gradually changing the display color and the characters in the ruby line in the second line area where the color has been changed are gradually erased, and the subsequent lyric text line is gradually displayed in the empty second line area by this erasure. Gradually erase the process and the color of the first line of the lyrics text in the first line area, and gradually erase the ruby lines of the lyrics text displayed in the second line area in the empty first line area. The lyrics display method includes the process of displaying.

  According to the present invention, even when lyrics synchronized with the performance of a song are displayed on a small display such as a portable information terminal, the lyrics to be sung in an instant can be read. In addition, you can understand the lyrics before and after the lyrics that should be sung, so you can get enough poetry. Thereby, since it becomes easy to use karaoke with a portable information terminal, the effect that a karaoke user increases can be anticipated.

=== Basic configuration of portable information terminal ===
The portable information terminal to which the present invention is applied can display a flash memory 102, a user interface device 103, an MP3 decoder 104, an audio amplifier, and a two-line character string as illustrated in the block configuration of FIG. A central control unit 101 including a liquid crystal display (display) 108 and including a CPU, a RAM, and a ROM controls and controls the whole.
The central control unit 101 decodes the high-efficiency compression-encoded digital music data such as MP3 format by the MP3 decoder 104, reproduces the accompaniment music data, and outputs the sound to headphones or the like. Further, the central control unit 101 sequentially develops the lyric characters of the song whose color is changed in synchronization with the performance on the video memory 105 based on the lyric rendering data attached to the music data, and performs the bitmap development on the LCD driver 106. The data is displayed on the display unit 108.
Music data and lyric rendering data are downloaded from the Internet via the network interface 107 or taken in by a memory card or the like and stored in the flash memory 106.

=== Configuration of Lyrics Rendering Data ===
As exemplified in the configuration of the lyric rendering data in FIG. 2, various data are attached to the lyric characters that are sequentially output as the performance progresses. That is, the character groups that are sequentially displayed / erased in synchronization with the progress of the performance are described in order.

  The attribute items “page” and “line” indicate a character display sequence. The page corresponds to the maximum display unit for one screen of the display. A line indicates a line number in one page. For example, 1 is set in the character group shown on the first line of the display 108. In this embodiment, either 1 or 2 is set. In particular, in this embodiment, a set of two lines of the lyrics text and ruby lines is taken as one page. That is, the same number of pages is set in the ruby line corresponding to the lyrics text.

  Attribute information such as “display timing”, “character code”, “type code”, “display layout”, “singing timing”, and “erasing timing” is added to each character assigned a serial number “character number”. The character code designates the address of the Kanji ROM, and the central control unit 101 can extract a predetermined character by referring to this. The type code is an identification code that classifies the type of lyric characters such as the lyrics text, solo song, duet part (male / female), and ruby. The display layout indicates the coordinates for displaying characters on the display unit 108. The display timing indicates a time when each character is to be displayed on the display unit 108, and the erasing timing indicates a time when each character is to be deleted from the display unit 108. Also, the singing timing indicates a time when the singer should sing. These timings are defined by the elapsed time from the start of the performance. In this embodiment, the time is counted by the tempo clock included in the karaoke data.

=== Lyrics display method ===
The configuration of the above-described lyrics rendering data is substantially the same as the conventional one except that the display timing and the erasing timing are set. The present invention is characterized by a method of displaying lyrics, and lyrics characters are displayed on the display unit 108 as will be described in detail below.

FIG. 3 shows a control processing flow for displaying lyrics in this embodiment. Moreover, the screen transition of the lyrics display is illustrated in FIG.
When the performance of the song is started, the central control unit 101 displays a character group of one page and one line (the first page of the lyrics text) on the first line of the display unit 108 based on the lyric rendering data. A character group of two lines per page (which is a ruby line of the lyrics text displayed on the first line) is displayed on the second line (s1 in FIG. 3). The display layout is set so that each ruby character displayed on the second line is displayed below each kanji displayed on the first line.

  Then, based on the singing timing of each character, the display color of the portion to be sung is gradually changed with respect to the lyric text on the first page in synchronization with the performance. At the same time, the ruby displayed on the second line is gradually erased (see s2, (a) to (b) in FIG. 4). In other words, the singing timing is set to the same value for the ruby in the second row corresponding to the character in the first row, and functions as a color change timing for the lyrics text. For ruby lines, the same value is set for the singing timing and the erasing timing. You may make it erase | eliminate with reference to a singing timing, without providing an erasing timing separately.

  Of course, the color of the ruby line may be changed at the singing timing and deleted immediately (after a certain time). In this case, a value after a certain time of the singing timing may be set as the erasing timing. Or you may make it erase | eliminate after the fixed time with reference to song timing, without providing an erasing timing separately. This makes it easier to confirm the color change position.

  Thereafter, the subsequent lyric text is gradually displayed in the blank portion after the ruby in the second line is erased (s2, (a) to (b)). In other words, the display timing of each character of the lyrics text on the second page may be set to be a certain time after the erasing timing of each ruby character on the first page.

  In this way, the lyrics text is displayed for a while after singing, and only the ruby line is erased. Ruby is unnecessary after singing, but if the lyric text remains after singing, you can look around the lyrics to sing, so you can lose sight of poetry all the time by following the face of the lyrics Disappear.

  Then, the entire text of the lyrics on the first page is displayed in a different color, and all the ruby text displayed on the second line disappears. When the text of the lyrics on the second page is displayed on the entire second line of the display 108, 1 The lyric text of the first page whose color has been changed from the line is deleted, and the entire ruby line of the second page is displayed instead (s3 to s4, (c) to (d)). That is, the same value is set for the display timing for each ruby character in one line. Of course, it is also possible to shift one by one and display one line in a short time.

  For each character in one line of the lyrics text, the erasure timing is set to be the same as or immediately before the display timing of the ruby line on the next page.

  Regarding the lyrics text on the second page, the display color of the part to be sung is gradually changed in synchronization with the performance. At the same time, the ruby displayed on the first line is gradually erased. Thereafter, the lyric text on the third page is gradually displayed in the blank portion after the ruby on the first line is erased (s5, (e) to (f)). Then, the lyrics text on the second page displayed on the second line is all displayed in a color-changed manner, and all the ruby text displayed on the first line disappears. When displayed in the entire eye, the entire text of the second page is displayed instead of erasing the second page of the lyric text displayed in the second line (s6 to s7, (g) to (H)).

  Then, for the lyrics text on the third page displayed on the first line of the display 108, the display color of the portion to be sung is gradually changed in synchronism with the performance, as in step 2 described above. Thereafter, the operations in steps 2 to 7 are repeated to display the lyrics text and ruby lines while changing the color.

=== Other Embodiments ===
In the above embodiment, the lyric text is left until the color change of the entire line is completed, only the ruby line is erased, and the subsequent lyric text is displayed gradually. However, the present invention is not limited to this, and not only the ruby line but also the lyrics text may be gradually erased from the part where the color change is finished, and the subsequent ruby line may be displayed.

  If you are passionate about following the lyrics, you may not be able to confirm the lyrics you've finished singing, and you may lose sight of the poetry. It is possible to prevent singing and stagnation. In other words, not only the lyrics of the lyrics to be sung, but also a room for poetry.

Although the portable information terminal provided with the karaoke performance function has been described in the above embodiment, the present invention can also be applied to a display device that can be interlocked with the karaoke apparatus. This display device has a hardware configuration including at least a central control unit 101, a flash memory 102, a video memory 105, an LCD driver 106, a network interface 107, and a display 108, and is connected via the network interface 107 (or depending on a storage medium). ) Import the lyric rendering data and perform the above lyric display processing.
A program for performing such lyrics display control is also an application target of the present invention.

It is the figure which illustrated the block configuration of the portable information terminal of a present Example. It is the figure which illustrated the structure of the lyric drawing data of a present Example. It is a control processing flow figure of the lyric display of a present Example. It is the figure which illustrated the transition of the lyrics display screen concerning a present Example.
