FIG. 1 is a diagram showing a configuration of a karaoke apparatus according to an embodiment of the present invention. The karaoke apparatus 1 (also referred to as “commander”) of the present embodiment is centered on a control unit composed of a CPU 14, a RAM 15, a ROM 16, and the like, with an HDD (hard disk) 13, an audio processing unit 18, a video processing unit 11, and an operation panel. 10 and a communication interface 17 and the like.

  The CPU 14, RAM 15, and ROM 16 constituting the control means are generally used in computers, and the CPU 14 stores various controls based on program execution and the like in the RAM 15, ROM 16, hard disk 13, and the like. , Based on various data.

  The voice processing unit 18 in the karaoke apparatus 1 is means for executing performance processing mainly based on performance information. The performance information includes data created based on the MIDI standard, as well as audio data in charge of chorus and the like. The audio processing unit 18 performs a desired musical piece by performing a musical performance process based on performance information corresponding to the musical piece designated by the user. Also, audio information input from a microphone connected to the audio input terminal and performance sound based on the performance information are mixed and output to an amplifier, and sound is emitted from a speaker connected to the amplifier. Note that an effect such as echo can be added to audio information input from the microphone.

  The video processing unit 11 executes processing for providing visual information to the user via the display 12 such as lyrics display processing and background video display processing. The lyrics display process is a process of displaying lyrics on the display 12 based on the lyrics information included in the music information, and is executed in synchronization with the performance process. In the lyrics displayed on the display 12, the part to be sung in color is displayed in synchronization with the performance, and the singer is instructed to sing. In addition, the background video display process is a process of raising the singing atmosphere by displaying various videos corresponding to the music to be played. For this reason, the hard disk 13 as the storage means stores the background video information compressed in the MPEG format or the like, and the video processing unit 11 displays the video on the display 12 by decoding the background video information. To do.

  The communication interface 17 is connected to the Internet via a network connection terminal, receives newly released music information, background video information, a program, and the like from a host device (not shown) and uses a history of the host device. Send. In recent years, it is also possible to provide a service suitable for each individual user by managing user information including a user's usage history, registered music, etc. with a host device and receiving it when the user uses it.

  Various instructions from the user such as music designation (reservation) performed on the karaoke apparatus 1 can also be performed from the operation panel 10, but usually a remote control device (not shown) connected to a network in the store. ) The remote control device is provided with an interface such as a touch panel, and can display and provide various types of information to the user, and can accept input by a touch instruction.

  The hard disk 13 functioning as a storage means stores music video information for playing music, background video information for displaying the background on the display, and a program for executing various processes in the karaoke apparatus. Yes. Further, by receiving various data from the above-described host device, addition and update of stored data are executed. The lyrics display process described in the present embodiment can also be added to the existing karaoke apparatus 1 by being received as a program.

Now, the lyrics display process that is a feature of the present invention will be described. FIG. 2 is a diagram showing a data structure of music information according to the embodiment of the present invention. The music information of this embodiment can use existing information. That is, it is possible to display romaji without performing any processing or modification on the music information. Thus, since the Roman letter display is performed by the program executed by the karaoke apparatus 1, it is possible to reduce labor and cost necessary for processing and modifying the music information. Furthermore, the storage capacity is not increased without increasing the amount of data for displaying Roman characters.

  As shown in FIG. 2, the music information includes metadata indicating various attributes of the music information, performance information used for performance, and lyrics information used for displaying lyrics. In the present embodiment, the metadata includes the song title, composer name, song number, genre, presence / absence of an individual material image, and the like. The song name, composer name, song number, and genre are used as information for searching and specifying the song. The individual material image is information indicating whether or not the background image has a specific material for the music, and if there is, an image specific to the music such as an artist's live video can be used. It is.

  The performance information of this embodiment is MIDI data created in accordance with the MIDI standard, but it is also conceivable to include audio information such as back chorus. In the case of MIDI data, a musical tone is played by causing a MIDI sound source as a performance means to perform.

  The lyrics information (telop data) is data for displaying lyrics on the display 12 in synchronization with the performance based on the performance information. In the present embodiment, block data to be displayed at a time at one timing is configured as a unit. Based on the step value output in synchronism with the performance information, the block data is read out and displayed, so that the lyrics display synchronized with the performance is executed.

  Each block data includes display data, attribute data, and ruby block data. The display data includes a character string of lyrics to be displayed (lyric character information) and coordinates for positioning the character string. In addition, it is possible to provide a plurality of block data to be displayed in one screen. By erasing the lyrics of the block data at the end of the singing and displaying the lyrics of the new block data, a smooth singing can be performed. Is possible.

  The attribute data is a data group including a character string included in the display data and information for determining display, erasure, and color change timing of the character string included in the ruby block data. In order to determine these timings, in this embodiment, they are associated with step values (MIDI step values) output in synchronization with the progress of the performance information. The display step and the erasing step are step values indicating the display timing and the erasing timing of the character string of the display data and ruby block data. The change step is a step value for starting the color change of the character string of the display data and the ruby block data, and in the present embodiment, the change step includes a change speed indicating the color change speed of the character string. . The attribute data also includes the number of ruby block data (the number of ruby blocks) included in the block data.

  The ruby block data is data for displaying ruby (reading kana: hiragana, katakana) for a character string (mainly kanji) of display data. Each ruby block data includes a character string (ruby character information) and a relative coordinate for positioning the character string.

The above is the data configuration of the music information of the present embodiment. However, the data configuration can be appropriately adopted as long as the gist of the present invention is not changed. Now, the lyrics information (block data) of the present embodiment and an example of the drawing result will be described with reference to FIG. FIG. 3A is an example showing block data of the present embodiment. In this example, various data indicating timing such as display steps are omitted. For the character string in the display data “Flight toward tomorrow” (hereinafter referred to as “main character string”), the hiragana ruby is applied to each of the kanji characters “Tomorrow”, “Direction”, and “Fly”. Yes.

  In the present embodiment, the coordinates for positioning the main character are represented by coordinates (number of dots) from the upper left of the screen to the upper left of the main character string. In the present embodiment, a font of a predetermined size is used for the character string to be displayed, and the main body character is positioned only by designating one point in this way. For positioning, not only one point as described above, but also an appropriate form such as designating the upper left and lower right of the main character string and displaying them in a frame determined by them can be adopted. In such a case, it is preferable to use a scalable font whose size can be freely changed.

  As for ruby, the hiragana characters “Asu”, “Mu”, and “To” will be assigned to the kanji characters “Tomorrow”, “Direction”, and “Fly”. The relative coordinates are specified. In this embodiment, the right direction from the coordinates in the display data is positive, and the number of dots up to the left end of the character string is defined. As with the main character string, Ruby uses a font with a predetermined size, so the vertical position in the screen is automatically determined based on the size of the font used. It is possible.

  An example of a drawing result based on such block data is shown in FIG. Although not described in FIG. 3A, the singer can recognize the singing location by changing the color from the left to the right of the main character string based on the change step in the attribute data. It becomes. Moreover, singing is further facilitated by changing the color of ruby in accordance with the color change position of the main character string.

  Now, a process for reproducing music information in the present embodiment will be described in detail. FIG. 4 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, the reproduction is started based on the read music information. Here, the performance process S200 and the lyrics reproduction process S300 are executed in parallel. The performance processing is executed by playing the performance information included in the read music information by the sound processing unit 18. 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 the performance information are sequentially output (S103). In the lyrics reproduction process S300, lyrics are displayed, erased, and changed in color based on the step values. The reproduction of the music information is executed until the performance process S200 and the lyrics reproduction process S300 are completed (S104).

  Now, details of the lyrics reproduction process S300 will be described. FIG. 5 is a flowchart showing the lyrics reproduction process according to the embodiment of the present invention. The lyric reproduction process is executed based on the lyric information in the music data, the font data for displaying the lyric characters, and the step value output with the performance process as shown in the upper right of FIG.

  The block data processing loop of S301 to S312 is sequentially executed for each block data included in the lyrics information. In S302, the step value output in the performance process is compared with each step (display step, erase step, change step) included in the attribute data in the read block data. In S303, S306, and S309, the process proceeds to subsequent processes based on this comparison.

  If it is determined that it is a display step (S303: Yes), first, a Roman character function operation check, that is, a check of whether or not it is currently set to perform Roman character conversion is executed (S304). The setting for performing Romaji conversion is set by a user's operation from various input means such as the operation panel 10 or a remote control device. This setting can be switched even during music reproduction. If the result of determination is that the Romaji conversion function is used (S305: Yes), the lyrics are drawn in Romaji conversion block drawing processing S500. On the other hand, when the function is not used (S305: No), the normal block drawing process is executed. These drawing processes will be described in detail later.

  As a result of the comparison with the step value, when it is determined that the step is a change step (S306: Yes), color change is performed on the character string (main character, ruby) of the block. This color change is a process in which the character string displayed on the screen is changed in order from the left end in the Romaji conversion block process S500 or the normal block drawing process S400, and the singing position is notified to the singer. This process is started at the timing of the change step included in the attribute data of the block data. In S307, based on the change speed included in the attribute data, the change width (number of dots) of color change to be changed in one drawing is calculated. In S308, color change drawing of the displayed character string is sequentially executed with the calculated change width. In this embodiment, the color change of the ruby character string is executed at the same horizontal position as the color change position with respect to the main body character string, and the singing position is more accurately grasped. In the present embodiment, one change rate is set for one block data. However, the change rate can be changed in the block data. In this case, the change timing and the changed change rate are required. .

  As a result of the comparison with the step value, when it is determined that it is an erasure step (S309: Yes), the character string (main part, ruby) of the block is erased (S310). By executing the above processing until the performance information is finished (S311: Yes), lyrics display synchronized with the performance processing is executed.

  Now, a normal block drawing process for displaying a character string of lyrics and a Romaji conversion block drawing process will be described in detail.

  FIG. 6 is a flowchart showing normal block drawing processing according to the embodiment of the present invention. When the normal block drawing process is started, first, the coordinates of the display data in the block data are read out in S401, and a reference position for arranging the main body character string is set. Subsequently, in the processes from S402 to S407, drawing for each body character of the body character string is executed. In S403, the characters of the display data are read, and drawing is performed with the font data corresponding to the characters read in S404.

  In S405, in order to position the character to be displayed next, the drawing X size (size in the horizontal direction of the screen) of the character drawn in S404 is acquired. In S406, the drawing position is advanced by the X size in order to position the character to be drawn next. By repeating the processes of S403 to S406 in this way, a character string (main body character string) in the display data is drawn.

  S408 to S416 are processes for applying ruby to the main body character string displayed in S401 to S407. This series of processing is executed by sequentially reading each ruby block data. In S409, the drawing start coordinates of the ruby to be drawn are set based on the relative coordinates described in the display data of the ruby block data and the coordinates in the display data. This is executed by adding relative coordinates to the coordinates in the display data. In this embodiment, since only the coordinate in the horizontal direction of the screen is set as the relative coordinate, the coordinate in the display data is used as the coordinate in the vertical direction of the screen.

  S410 to S415 are processes executed for each ruby block data, and are similar to the drawing of the main character string (S402 to S407). In S411, the character of the ruby block data being processed is read, and in S412, drawing is executed based on the font data corresponding to the character. In S413 and S414, position determination for drawing the next ruby character is executed. Thus, the ruby display of the main character string to be displayed is executed by repeating the processing of S410 to S415 for each ruby block data.

  The normal block drawing process has been described above. Next, the Roman character conversion drawing process will be described with reference to FIGS. 7 and 8 are flowcharts showing the Romaji conversion block drawing process according to the embodiment of the present invention. In particular, FIG. 7 is a process for displaying the main character string, and FIG. 8 displays the ruby character. It is processing to do. In addition, the circle B in FIG. 7 indicates that the circle continues to the circle B ′ illustrated in FIG. 8.

  S502 to S516 shown in FIG. 7 are processes for drawing the main body character string. By repeating these, the character string in the display data is drawn on the screen. In particular, in this embodiment, singing a phonetic character having a certain reading such as hiragana or katakana to a user who is difficult to interpret Japanese, such as a foreigner, by converting it into a Roman character using an alphabet. Trying to make it easier. In particular, conversion to Romaji is performed during the music playback process, so it is not necessary to prepare music information (especially lyrics information) in advance or to change the music information. It is possible to add functions while reducing the number of functions. Further, since conversion is performed during music reproduction, a storage capacity for converted Roman characters is not required, and the amount of music information is not increased.

  In S503, one character of the character string is read out from the display data, and drawing is performed on the screen based on the corresponding font data in S504. In S507, it is determined whether the drawn character is a phonetic character, that is, hiragana or katakana. In the present embodiment, when the main body character is a phonetic character in this way, the main character is converted into a Roman character and the ruby is shaken in the following processing (S508 to S515). If it is determined in step S505 that the character is not a hiragana or katakana character, the process proceeds to steps S514 and S515, and a process for determining a reference position of a character to be drawn next is executed. Proceed to ruby block processing.

  If it is determined in S505 that the character is hiragana or katakana, first, the reference position is moved for ruby drawing (S506). In the present embodiment, a position moved by a predetermined amount in the screen vertical direction (Y direction) from the reference position for drawing the main character is set as the reference position for ruby drawing. In S507, it is determined whether or not the character currently being processed is a stuttering sound, or “cha” or “yu” in “Cha” or “Kyu”. In the case of stuttering, since the processing has been completed in S508, the reference position is returned to the position for drawing the main character without drawing (S513), and the process is exited.

On the other hand, if it is determined that it is not a stuttering, it is determined in S508 whether or not the next character is a stuttering. If the next character is not a stutter (S508: No), the character is in normal character notation, and therefore the Roman character conversion process is executed for one character being processed in S509. This romaji conversion process is a simple process of converting hiragana or katakana into romaji, and can be executed using a simple conversion table. For example, in the case of “A” and “K”, “A” and “Ki” are converted into one or two alphabets. In S510, the Romaji converted at the reference position moved in S506 is drawn.

  When it is determined in S508 that the next character is a stuttering, a Roman character conversion process including the next character (sounding) is executed (S511). For example, in the case of “Gya” and “Pyo”, they are converted to “Gya”, “Pyo” and three-letter alphabet. Depending on the conversion rule, “ja” may be converted to a two-letter alphabet such as “Ja”. In S512, the ruby converted to Romaji is drawn on the screen.

  FIG. 9 shows a lyric display example of “all ruby” music according to the embodiment of the present invention. Here, “all ruby” music refers to music in which ruby is provided for all kanji used in the main character string. FIG. 9A shows a lyric display by the normal block process, and FIG. 9B shows a display example of the Romaji conversion block drawing process. The user can switch these display forms by using an input unit such as the operation panel 10. Further, as can be seen from the conversion example in FIG. 9, the rubies “He”, “Ke”, “Te”, “Be” in Roman letters are used for the main characters “he”, “ke”, “te”, “be”. "Is attached.

  The flowchart shown in FIG. 8 is a continuation of the flowchart of FIG. 7 and mainly shows processing for ruby blocks. In the processing of S517 to S532, processing performed on each ruby block is shown. By executing this processing for each ruby block, the ruby conversion of the ruby originally attached to the kanji is executed.

  In S518, a relative coordinate serving as a reference position for drawing is read out from the read ruby block, and a reference position (drawing start coordinate) for drawing a ruby character based on the coordinates in the display data is read. Is set.

  The processing of S519 to S529 is processing performed for each ruby character. In S520, one character in the character string in the ruby block data is read. In S521, the size in the horizontal direction of the screen (X size) necessary for drawing the font corresponding to the character is acquired. In S522, the X size is added, and the size in the horizontal direction of the screen necessary for drawing the ruby character string in one ruby block data is calculated.

  The processing of S523 to S528 is the Romaji conversion and drawing processing based on the presence or absence of stuttering, as in the case of processing the main body character string. In the present embodiment, drawing is performed in the buffer area without drawing on the screen in S526 and S528. This is because, in later processing, drawing is performed in consideration of the size of the ruby character string converted into Romaji.

  When the drawing of the ruby character string in the ruby block data (in this case, drawing in the buffer area) is completed, the process exits in S529, and enlargement / reduction of the character string drawn in the buffer area is executed in S530. This process is a process of enlarging or reducing to the original ruby character string size (in the horizontal direction of the screen) calculated in S522.

FIG. 10 is a diagram showing an example of the ruby reduction process after Romaji conversion executed in S530. Consider the case where Romaji conversion is performed for the ruby character string “ASU”. Since the Ruby character string after Romaji conversion becomes “Asu” and is represented by three characters, the size in the horizontal direction of the screen becomes larger than the original two-character representation. Therefore, in the present embodiment, the size in the horizontal direction of the screen is converted (reduced) to the size of the character notation before conversion, and even when the number of characters increases, It is possible to prevent duplication and make ruby characters easier to see. Also, the color change of characters is executed at almost the same timing as the character notation before conversion, so that it is possible to ensure the ease of singing even after the Roman character conversion.

  In S531, the ruby character string in the buffer area enlarged / reduced in S530 is drawn on the screen. The above processing is executed for all the ruby blocks, and a series of processing ends. As mentioned above, although the lyrics display process in this embodiment was explained, in this embodiment, in the lyrics display process performed at the same time as the performance process during the reproduction of the music information, ruby Romaji conversion is performed, There is no need to add or change lyrics information for romaji display.

  In the above-described embodiment, “all ruby” has been described. However, there is a piece of music in which ruby is provided only for some Chinese characters. FIG. 11 is a display example when the lyrics display processing of the present embodiment is applied to music that is not “all ruby” in such a case. In the present embodiment, for characters that do not have phonetic characters (in this case, “Tomorrow”, “Direction”), the Roman character conversion cannot be executed, so the display form as shown in FIG. turn into. However, even if there are several characters that cannot be sung, there is little impact if seen from the whole song, and also from the effect that it can be handled only by the program for lyric display processing without modifying the music information, Such “all ruby” has great significance to be applied to internal music.

  FIG. 12 is an example summarizing the lyrics conversion process and the modification examples according to the embodiment of the present invention. In the figure, the kanji characters that do not have the ruby indicated by 1, 2, and 5 are not attached with the ruby characters in Roman letters. On the other hand, since 3, 6, 8, 9, 12, and 14 in the figure are hiragana or katakana characters that can be uniformly converted to Romaji, the rubies converted to Romaji are written above each main character. Become.

  Here, as shown in FIG. 8, when the main body character or ruby character includes the prompt sound “tsu”, it is preferable to refer to the next character and convert it to the Roman character. In this case, since it is “te”, the consonant part “t” of the next character “te” is converted as the ruby of the prompt sound “tsu”. In addition, in the case of “hssa”, the consonant part “s” of “sa”, which is the next one of the prompt sound, is converted as ruby.

  As an example of such a conversion rule, it is preferable to consider a long note “−” used for “tower” and the like. In the case of “tower”, the character “wa” one character before is referred to. Specifically, the vowel part “a” of the character one character before is converted as a ruby of “-”. .

  In the present embodiment, when the main character is a katakana character, ruby is displayed in a display form (in this case, italic characters) that can be distinguished from a hiragana character. When the main character is Katakana, it is often a foreign character based on English, and by displaying such characters in a different form from that of Hiragana, users such as foreigners can sing more easily Become.

FIG. 13 shows an example of a further application example. FIG. 13A shows a notation example before Romaji conversion, and FIG. 13B shows a display example after Romaji conversion. Yes. When the reading kana covers a large number of characters such as “曙”, the number of characters can be further increased when converted to Roman characters. In the present embodiment, since hiragana and katakana are also displayed as ruby, there is a concern that ruby will be displayed in duplicate (in this case, “He” adjacent to “AKEBoNo”). For this reason, in the present embodiment, the ruby converted from the originally attached ruby and the ruby converted from the hiragana and katakana characters in the main body characters are displayed on different levels.

  By displaying in different stages in this way, it is possible to avoid the converted Roman characters from being displayed in duplicate and to improve the ease of interpretation. In addition, in this embodiment, when displaying on different levels, the hiragana and katakana parts of the main body characters are compressed vertically to form a space necessary for ruby notation, but this form is not essential. .

  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.
