The center 1 has a character string storage means 11 in which character information composed of the font ID and character codes is stored. A face/metric selecting means 3 references a usable font ID display table 24, a font ID table 21 and a replacement metric table 25 and outputs the face ID and the metric ID to a character developing means 4 when the prescribed font ID is supplied to this means. This character developing means 4 selects the face data assigned by the face ID from the face data 22 and develops the characters corresponding to the character codes supplied from the center 1 based on face data. A character layout means 5 selects the metric data assigned by the metric ID from the metric data 23, executes layout of the characters in accordance with the metric data and outputs the layout to a display device.
Description
The invention relates to the character display device that shows the character of representing by the character code that information center provided in terminal, especially in regard to character display device according to the data presentation of character kind that provides and character size character string attractive in appearance.
In the compunication always, personal computer is mutual, perhaps personal computer is connected to mainframe computer and receives under the data conditions, with character code (for example, JISX 0208-1990 message exchange encode Chinese characters for computer, to call the JIS code in the following text) form transmission, show and character code is transformed into character in terminal (personal computer) side.
In this case, be character code owing to what transmit, the font of character and size etc. show with the selected type body of end side.
And if treat as figure with character, as pictorial data transmission, though can be shown by the various characters of transmitting terminal (information center) appointment, because of pictorial data is a pixel data, data volume is just big especially, is not suitable for high-speed transfer.
In addition aspect, in the middle of general word processor and DTP (desk-top reprinting) device, might adopt multiple character type body.These devices maintain the type volume data as each character such as the shape and size, word width of character, rely on and specify this type volume data, just can use desirable character type body.
Thereby in compunication, for show various characters in terminal, it also is possible sending character code by the type body that designated terminal maintained.
And just popularize to adopt in recent years, deposit the accompaniment data and the lyrics data of multiple melody in information center, the terminal of filing a request is transmitted the communication type Caraok device that corresponding melody accompaniment data and lyrics data are played, shown.In this case, lyrics data and accompaniment data are simultaneously, though,, require to show the character of various fonts and size because of the very strong recreational factor of Caraok device because of transmitting the few character code of data volume with the restriction of high as far as possible speed transmission.
And, among English digital etc.,, require also to consider as far as possible that this situation changes character pitch to show character string attractive in appearance to each character because character is wide different and different with each character.
Moreover, not only to show the lyrics in turn, but also require to carry out the practicality demonstration that note waits with phonetic notation (phonetic annotation of Chinese characters).
Thereby in existing communication type Caraok device, when the Chinese character lyrics of reading in difficulty are carried out phonetic notation, be that the character string of phonetic notation part and the character string of the lyrics are handled respectively.That is in the coordinate values (arrow A) of the start-up portion of specifying lyrics string with when showing the lyrics, the character string of phonetic notation part is then shown with the coordinate values (arrow b-e) of specifying its start-up portion at each phonetic notation group of each Chinese character respectively.
In the kind of a plurality of terminal link informations center, the character type body that specify to show by the center and send under the situation of structure of character code, though deposit there is not what problem aspect the character type volume data of the specified all kinds of information center in whole terminals, but in purposes and being provided with on the mutual relationship of space, cost etc., under the situation of the terminal of the character type volume data of a part of type in having the specified character type body in the center of only depositing, terminal will occur and can't rely on the problem that shows by center designated character type body.
When the character type body of having specified terminal not deposit, substitute as other character type body of being held with this terminal, because the size of character is different and different because of character type body type with the character pitch, during the character display sequence and the state that sent of information center can be inconsistent, being limited to character string itself has various understandings, just might occur exceeding picture and the situation that can't read the part character.
In addition, when in communication type Caraok device always, being added with phonetic notation, be necessary for each group phonetic notation and specify the display seat scale value, thereby the information that increased sending data.
And as one of practical situation, consider according to carrying out same processing with phonetic notation, can utilize outer literal to wait the chord name that the center is sent to be shown in the demonstration situation of chord name of guitar chord etc.Change the music tonality in end to change the tone of playing then, chord when weak device will be set on guitar merges under the situation about showing, though also necessary to showing that chord carries out transposition, just can't be when merely only showing the character data of sending here by the center with the in addition transposition of demonstration chord.
Therefore, purpose of the present invention is exactly by providing, even do not deposit in terminal under the situation of character type body of information center's appointment, the also character display device that can show with the character type body that the specified character type body in center is selected to show in the layout in the same manner is can always demonstrate character string attractive in appearance.
In addition, the present invention also aims to provides, only sending in the character code data by information center, can be attached to the demonstration of phonetic notation on the character string of the lyrics etc. etc. in end side, and can be with chord name that the center sent in conjunction with musical instrument user's use shape history change and the character display device that shows.

Fig. 2 is the structural drawing of explanation character display device first embodiment of the present invention.Though information center 1 has been connected a plurality of terminals, has only made the terminal 2 of one of them in this figure.
Here, type body ID show by appointment the layout information of character rhythm data (back explanation) rhythm ID and specify the font ID of the font data (back explanation) of the font show character to form.Type body ID for example stores with rhythm ID and each 8 bit of font ID then as shown in Figure 3 in pairs.The kind of type body ID is identical with the quantity of the kind of font data (is the K kind at this), and in the character string storage means 11 at center 1, is suitable for font, the layout that this character information shows most for specifying, and storage is by the type body ID that selects among the K kind.
In Fig. 2, terminal 2 is by font, rhythm selection approach 3, and character launches means 4, character layout means 5, type body ID table 21, font data 22, rhythm data 23, type body ID indicator gauge 24 that may adopt and alternative rhythm table 25 constitute.
And font data 22 is the font of the character that is defined as Ming Dynasty's body, garden boldface type, right angle boldface type etc., and each font is categorized into font data I respectively, and (the m kind, the alphabet font of K 〉=M) is defined to font data m.Though the kind number of this font data 22 is same kind with the font ID of information center 1 (type body ID) and identical species number (m=K) preferably can be set, but deposit all character glyphs because of remembering, even if a kind of font data also must sizable memory capacity.Therefore, wait according to the price of terminal 2 and purposes and arbitrarily be equipped with kind quantity (K＞m) is a reality.Adopt this font data I any font to the font data m then to specify by font ID actually.
Rhythm data 23 are the data that show the character layout information, specifically, the character duration of the non-linear character of the height of definition character, Chinese character etc., the character of each characters of linear digital such as English digital is wide etc.Though these rhythm data 23 are determined defined each font data 22 of various fonts, even but font data 22 is inequality, because when the content of rhythm data 23 is identical, the content of rhythm data 23 (rhythm data 1-rhythm data h), than the also few h kind of font data 22 (during k＞h), may be all corresponding to k kind font data 22.And because these rhythm data 23 data volumes are little, the kind (m number) of tube terminal 2 font data of being stored is not how, has always deposited and the corresponding h kind of k kind font data (all) rhythm data 23, and each terminal all has the data of same content.
Type body ID table 21 shows and corresponding each rhythm data of k kind font data that ID stores rhythm ID respectively according to k kind font.This also is the table of a same content in each terminal.
Can applicable type body ID indicator gauge 24 be used to show the kind of terminal 2 stored font datas 22, contrasting this can just can understand adoptable type body in this terminal 2 by applicable type body ID indicator gauge 24.This can applicable type body ID indicator gauge 24, because of the kind with stored font data 22 in the terminal changes, and sets separately in each terminal.
Substitute rhythm table 25, under the situation that does not have type body ID with rhythm ID identical with the type body ID that shows, as showing the table that is used to explore the rhythm ID that substitutes ID, to specify alternative rhythm ID than the rhythm data of littler (size of each character) the character size ground of the original rhythm ID appointment of the size of each character (in turn near) to arrange priority at each rhythm ID, and award and show.Alternative rhythm ID shown in this alternative rhythm table 25, though only also can select with terminal 2 in stored font data 22 corresponding rhythm ID show, but also stored font data 22 in the tube terminal 2 not shows the rhythm ID that can substitute among whole rhythm ID.In this case, because all terminals all can be used the alternative rhythm table 25 of common content,, substitute rhythm table 25 with regard to unnecessary transformation in conjunction with the storage font data 22 of terminal 2.In the present embodiment, adopt the table that shows the rhythm ID that substitutes among whole rhythm ID.
And in the terminal of depositing with the font data 22 of the species number identical type quantity of the font ID (type body ID) of information center 1, owing to may show with the type body of the type body ID appointment that provided, thereby need not this alternative rhythm table 25.And when not storing all font data of k kind, even storage has the font data that corresponds respectively to rhythm data 1-rhythm data h separately under one the situation in terminal 2, because the identical corresponding font data of rhythm data of rhythm data of a rhythm ID appointment that provides with information center must be provided, also need not to substitute rhythm table 25 in this case.
Font, rhythm selection approach 3 are when being provided the type body ID of regulation by the character string storage means 11 by information center 1, promptly with reference to can applicable type body ID indicator gauge 24, whether docuterm graphic data 22 deposits the indicated font data of type body ID that is provided, if deposited, the type body ID that is about to be provided exports character to and launches means 4.As do not deposited, promptly with reference to type body ID table 21, retrieval has its allothimorph ID of the rhythm ID identical with the rhythm ID that comprised among the type body ID that is supplied with, if deposited in the font data 22, just this type body ID is exported to word character expansion means 4.And under its situation about not depositing, then substitute rhythm ID with reference to substituting the retrieval of rhythm table 25, retrieve the type body ID with this alternative rhythm ID by type body ID table 21, the rhythm ID that will form the font ID of its type body ID and the type body ID that composition is provided again exports character to and launches means 4.
Character is provided by the font data of means 4 by type body ID (rhythm ID and the font ID) appointment of selecting font, rhythm selection approach 3 to be provided among the font data 1-font data m that is had in the font data 22, the corresponding character of character code that will provide with the character string storage means 11 of information center 1 according to selected font data is launched, and exports to character layout means 5 simultaneously with rhythm ID.
The rhythm data that character layout means 5 are indicated by the rhythm ID that selects character expansion means 4 to be provided among the rhythm data 1-rhythm data h that leaves in the rhythm data 23, according to carrying out the character that provided layout is in addition exported to display device 6 with selecteed rhythm data.
In the character display device of said structure,, the process flow diagram shown in contrast Fig. 4 is described in more detail about the selection operation of font data in font, the rhythm selection approach 3 and rhythm data.
And the type body ID that information center 1 is provided as given FID, form this given FID font ID as given GID, rhythm ID as given MID, and the font ID that specifies the font data 1-font data m that font data 22 that terminal 2 is had deposits as GID1-GIDm, correspondingly rhythm ID as MID1-MIDm, by its type body ID that forms as FID1-FIDm.And will indicate the font ID of the font data of last application and rhythm data and rhythm ID respectively as use GID, use MID, will substitute rhythm ZD as alt MID.
At first, when information center 1 gives removing from mould body ID (given FID)) can be retrieved whether there is the sequence number (i) (whether font data 22 deposits the font data i that shows given FID) (step 31) that shows the type body ID (FIDi) identical by applicable type body ID indicator gauge 24 to reference with given FID, when having sequence number (i) (step 31 becomes Y), be about to constitute the given GID of given FID and given MID and export character to as use GID and useMID respectively and launch means 4 (step 32).If there is no sequence number (i) (step 31 is N) is promptly retrieved its allothimorph ID (FIDi) with rhythm ID (MIDi) identical with the rhythm ID (given MID) that constitutes given FID with reference to type body ID table 21.And in type body ID table 21, have under the situation of one or more these FIDi, promptly with reference to can applicable type body ID indicator gauge 24, whether retrieval is the sequence number (i) (step 33) that is indicated as the FIDi of this order, if exist sequence number (i) (step 33 is Y), being about to constitute the GIDi of this FIDi and MIDi (perhaps given MID, content is identical) exports character to as use GID and use MIDi respectively and launches means 4 (step 34).
And under the situation that ought not have other GIDi with MID identical with the given MID that constitutes given FID, (step 33 is N), then with reference to substituting rhythm table 25, retrieval is directed to the alternative rhythm ID (alt+MID) (step 35) of given MID.The body of contrast type again ID table 21, the retrieval tool is deposited the type body ID (FIDi) of the MIDi identical with the highest alt MID of preferred sequence, whether contrast can applicable type body ID indicator gauge 24 retrievals exist the sequence number (i) (step 36) that shows this FIDi in proper order, as have sequence number (i) (step 36 for Y), be about to constitute the GIDi of this FIDi and given MID that information center 1 is provided and export to character as use GID and useMID respectively and launch means 4 (step 37).Under the situation that does not have the MIDi identical (step 36 is N), preferably get time one preferential alt MID (step 38) of high order with the highest alt MID of priority.Repeating step 36 carries out identical processing until choosing whole altMID (step 39 is N).When selecting all alt MID still not have the situation of identical MIDi (step 39 is Y), promptly do not deposit the situation of energy ground attractive in appearance character display type body and show make mistakes (step 40) because of becoming terminal 2.
Like this, even selecting under the situation of font data with reference to substituting rhythm table 25, because exporting the rhythm data (use MID) of character expansion means 4 to is given MID that information center 1 provides, the layout of character promptly with specified identical of information center 1, can not occur that character string exceeds the display frame of display device 6 and situation about can't understand yet.And the font data of this moment is owing to be that the order that the size by character reduces is selected, and it is overlapped and cause various identification also to be unlikely character when utilizing given MID.
In storages all k kind font data 22 these extreme cases are arranged, even in terminal 2 grades of depositing minimum each one font data that corresponds respectively to rhythm data 1-rhythm data h, do not substituting under the situation of rhythm table 25, because step 33 must become " Y " in Fig. 4 process flow diagram, so just do not need step 35-step 40.
Even increase font data newly in the font data 22 of terminal 2, if rewrite can applicable type body ID 24 content just can be used.Though character string display partly is not illustrated in the above-described embodiments, but when character display device of the present invention being applied to the situation of Caraok device for example etc., promptly become known on the background images that makes with accompaniment music when synchronous the technology of double exposure captions etc.
Character display device of the present invention is to detect control character in the string data of the regulation of being supplied with by this information center and second character data is arranged into a plurality of terminal of exporting to display device in the character string that first character data forms is again constituted by depositing a plurality of information centers and relying on by first character data and the composite string data of second character data that differentiates mutually by control character and this first character data.Utilize this structure just might show various practical information.
As second embodiment of character display device of the present invention is the lyric display equipment that in addition phonetic notation (additional with Chinese-character pronunciation) is provided on the Chinese character of character string of the lyrics that provided by information center etc. and shows in end side.
Fig. 5 is the structural drawing that shows as the lyric display equipment of second embodiment of character display device of the present invention.Though be that an information center is connected with a plurality of terminals in the communication type lyric display equipment, in this figure, only express one of them terminal.In the situation that this lyric display equipment is made the communication type Caraok device, roughly has same structure, as long as just can realize with increasing function associated such as employed performance is set in the common communication type Karaoke on the function that terminal indicated among this figure and information center had.
Among Fig. 5, information center 1 among information center 10 and Fig. 2 is same structure, the lyrics data of the song that quantity is a lot of is purchased precedent as the music data storehouse 30 with the storage of type body ID and character code form, and the lyrics data of the song that terminal 20 is required sends to the terminal 20 that claims.
Terminal 20 is provided with phonetic notation information separated unit 40, character launches unit 50, type volume data unit 60, character position computing unit 70, row layout units 80 and interim memory cell 90.The character that character expansion unit 50 then is provided with the terminal 2 of Fig. 2 launches means 4 and font data 22.60 of type volume data unit be provided with the terminal 2 of Fig. 2 font rhythm selection approach 3, type body ID table 21, substitute rhythm table 25 and can applicable type body ID indicator gauge 24.
The type volume data unit 60 that the type body ID of the lyrics data that information center 10 sends, character code are offered terminal 20 respectively, phonetic notation information separated unit 40.Type body ID as contrast Fig. 1 is illustrated, offers character and launches unit 50 after type volume data unit 60 is handled.Character code detects the phonetic notation control character through phonetic notation control character separative element 40, is separated into character string that shows the lyrics and the character string that shows phonetic notation.
The information that character position computing unit 70 is provided according to phonetic notation information separated unit 40, calculate the initial coordinate position of the character string that shows the lyrics, simultaneously phonetic notation control character number before the phonetic notation and phonetic notation number are counted, calculated phonetic notation display seat cursor position, export to capable layout units 80.
Character launches unit 50 with reference to the given type volume data (type body ID) in type volume data unit 60, and the character code that phonetic notation information separated unit 40 is provided is launched into character, exports capable layout units 80 to.
Row layout units 80 is utilized interim memory cell 90 that phonetic notation is arranged and is exported display device 100 in position and with the lyrics, so that show the lyrics with phonetic notation.
By above-mentioned such structure, for example when providing the character code that shows the lyrics shown in Fig. 6 by information center 10, just may be with indicated state in display device 100 displayed map 7 that are connected to terminal 20.
In the character string shown in Figure 6, be the phonetic notation control character, be 1 byte code with the part shown in (Le PVC).Phonetic notation then provides with the form of holding under the arm in the phonetic notation control character in showing the character code string of the lyrics, relies on to detect the control that this phonetic notation control character carries out adding in terminal 2 sides phonetic notation.
The character of holding under the arm by the phonetic notation control character (phonetic notation), make on the character in its tight the place ahead that is attached to the preceding phonetic notation control character of this phonetic notation, before this phonetic notation, provide continuously under the situation of several phonetic notation control characters, on n the character that begins by the tight the place ahead of phonetic notation control character character, evenly imitate the ground that distributes and show.
The size that is used as the character of phonetic notation among Fig. 7 be about the character that shows the lyrics itself size 1/4.And the position of the bebinning character of character string (the initial coordinate of the demonstration of character string: though arrow a) provide by center 10, not the designated character string midway other characters and the display position of phonetic notation, and decide these display positions by character position computing unit 70.
To offering terminal 20 with the character code shown in Fig. 6 by information center 10, the concrete processing procedure when showing the lyrics as shown in Figure 7 in display device 100 is illustrated now.
At first, on the reference position of character string, show Chinese character " heart ", then since occur as control character (Le PVC), so the small characters that shows " the こ こ ろ " that held under the arm by (Le PVC) in this Chinese character " heart " top is as phonetic notation.
And after showing " the cold い of Ga night " character string, (Le PVC) held under the arm " going up " character that is arranged in the tight the place ahead of (Le PVC) with small characters " night " top.Similarly, after character string " mist " showed, its top promptly was attached to phonetic notation " I り ".
Then, after character string " To one people " shows, because to be begun by two (Le PVC) then be character " ひ と り " and (Le PVC), so in the top uniform distribution phonetic notation " ひ と り " of two preceding characters of (Le PVC) " people ".At last, display string " ず む ", thereby show the character string shown in Fig. 7.
Here, processing under the phonetic notation situation that additional a plurality of (m) character that distributes with equalization to one or more (n) character top is formed, by being calculated to the phonetic character number (m) of input with by the number of characters (n) of additional character, perhaps reference table, derive the reference position of phonetic notation and the interval between phonetic character, and can carry out uniform distribution at each number of characters.
Top character code is handled and is shown promptly as shown in Figure 8 with process flow diagram.And is identical with reference Fig. 4 to the explanation that type body ID handles.
At first, whether by the character code that information center 10 provides, differentiating is phonetic notation control character (step 101).As non-phonetic notation control character (step 101 is N), because be the character code that shows the common lyrics, so by showing (step 111) with the corresponding character former state of this character code.Be under the situation of phonetic notation control character, (step 101 is Y), whether as n=1 (step poly-102), differentiating next character is phonetic notation control character (step 103) with phonetic notation control character number.
And in the situation (step 103 is Y) of phonetic notation control character, make the phonetic notation control character count n and add one (step 104), whether be phonetic notation control character (step 103), then still for the phonetic notation control character time, continue to increase the phonetic notation control character and count n if differentiating again next character.Under the situation of non-phonetic notation control character (step 103 is N), owing to be the character code of expression phonetic notation, begin (step 105) with the number of characters m=1 of phonetic notation, store its character code (step 106).And, because up to the phonetic notation control character all are character codes of expression phonetic notation, so whether differentiate next character is phonetic notation control character (step 107), when the situation of non-phonetic notation control character (step 107 is N), phonetic character is counted m add one (step 108), store its character code (step 106).Repeat said process to the phonetic notation control character.When becoming the phonetic notation control character (step 107 is Y) because be the termination that shows phonetic notation part, so by show character before the last lyrics character that is shown begins to n above demonstration m the phonetic notation (step 109) that evenly distribute.Repeat above-mentioned processing then, until end of string (step 110).
Such as described above, in the present embodiment, utilize the phonetic notation control character, because also include phonetic notation and transmitted, so just be necessary phonetic notation is handled as another row in the character string that is used for showing the lyrics.And owing to add the character of phonetic notation according to the continuous quantity decision of phonetic notation control character, as long as this quantity and the phonetic notation number of holding under the arm in the phonetic notation control character are counted, just can phonetic notation in addition on the tram, and thereby needn't organize phonetic notation for each and specify its display seat scale value, also just can reduce the data of transmission.Even under the situation that stops the phonetic notation demonstration, as long as also can only make end side not show the control of holding the phonetic notation in the phonetic notation control character under the arm, thereby the conversion that can show simply, not show.
Below to as the 3rd implementation column of character display device of the present invention, show that by information center's transmission the character code (Charactar code) of the lyrics is together with chord data (Chord data), and show in end side and the communication type Caraok device of the lyrics and chord name (Chord name) to be illustrated in conjunction with the accompanying drawings.
Fig. 9 is the structural drawing that shows the general picture of third embodiment of the invention communication type Caraok device.Though have a plurality of terminals to be connected to an information center in the actual communication type Caraok device, and only made one of them terminal in the figure.And in the function of terminal and institute of information center tool, also only shown the part relevant with the present invention, all dispense with the outer function associated major part of performance.
The music data storehouse 230 of depositing the numerous song data that comprises such performance data relevant with song and lyrics data etc. is purchased by information center 210, and the song data of terminal 220 desired songs is sent to the terminal 22 that claims.
Terminal 220 is provided with data decomposition unit 240, lyrics generation unit 250, type volume data 260, chord generation unit 270, pitch conversion controller unit 280, chord TCU transfer control unit 290, row layout units 300 and performance unit 310 etc.
The song data that is provided by information center 210 240 carries out data content and decomposes through the data decomposition unit, is separated into various data and is exported.
Lyrics generation unit 250 will be transformed into character string by the lyrics data that data decomposition unit 240 provides with reference to type volume data 260, export to capable layout units 300.
Chord generation unit 270 will be transformed into chord name by the chord data that data decomposition unit 240 provides with reference to type volume data 260, export to capable layout units 300.At this moment, according to the control signal that the style that provides simultaneously with chord data and pitch conversion control module 280, chord TCU transfer control unit 290 are provided, the chord name of output is changed (transposition).
Row layout units 300 chord name that chord generation unit 270 is provided is arranged in the lyrics that lyrics generation unit 250 provided, and exports display device 320 to and shown.At this moment, show that when being selected as chord OFF when (not showing), only exports the lyrics that lyrics generation unit 250 is provided; And when selecting chord to show ON (demonstrations), the Building Y of the display position of each row of the character string that shows the lyrics marked revised, make and in the ranks separate, and between this row that separates, arrange and exported with chord name.
Play generation and output accompaniment musics such as such performance data that unit 310 is provided by data decomposition unit 240.And can change interval according to the control signal that pitch conversion control module 280 is provided.
At least include lyrics data, chord data, tonality and such performance data by information center 210 to the song data of terminal 220 outputs.And adopting under MIDI (the musical instrument digital interface Mnsical Instrument Digital Intarfce) situation of signal (standard MIDI file) as such performance data, because except that the midi event of storage playing information, also include storage and may deposit metaevent beyond system's mutually exclusive events of arbitrary data and the playing information, thereby can import the data that show the tonality in the metaevent and sent again.
The chord data that shows chord name is recorded and narrated the chord control character＜コ-De as a syllabified code in the character code string of lyrics data〉record and narrate the chord data that shows chord name thereafter.Just needn't guarantee special data area in this case for showing chord name.And owing to the chord data that can not show continuously more than two, and when chord data made following detailed description such fixed length data, also just needn't use the chord control character that shows that chord data finishes, and can adopt a chord control character that begins part as just chord data.
Below the transposition of being carried out in the chord data that provided by information center 210 and the chord generation unit 270 is handled and be illustrated.
Chord data by information center's 210 supplies, for example say, be two byte datas that constitute by polyphonic ring tones 6 bits and basses body with cord and 5 bits and 5 bits,, just can show for example such chord name shown in this figure (B) according to adopting the data structure shown in Figure 10 like this (A).It then is the chord data that is provided at information center 210 that the transposition of being carried out in the chord generation unit 270 is handled, the control signal that is provided according to pitch conversion control module 280 and chord TCU transfer control unit 290, the number of degrees that carry out the tonality of the reality supplied with respect to information center 210 change, and resulting chord name is shown thus.
In Caraok device, have a lot of pitch conversion functions that the interval of accompaniment music can be changed over the interval that the singer easily sings.This pitch conversion function is provided with the action button that can regulate in the scope of common-6-+6, can make the pitch changing of each semitone.Thereby along with the change of this tone, the demonstration of the tonality of chord name also is necessary to be moved.In the present embodiment, pitch conversion control module 280 is according to the variable quantity of pitch conversion, sending signal to performance unit 310 so that in the interval variation of accompaniment music, also will transmit control signal to chord generation unit 270 shows with the tonality that changes chord name.
And playing under the situation of guitar etc., be to adopt mute to play simple chord.For example, when actual chord is Eb (fall E transfer), mute is contained on three sound columns plays the C chord.In this case, promptly not Eb but the show state of the C chord that is easy to differentiate.Thereby, in the present embodiment, chord translation function (off beat function) is set, specifies number of degrees transfer amount by action button in terminal 220 sides, chord TCU transfer control unit 290 is carried out the demonstration at the number of degrees conversion of actual tonality to chord generation unit 270 output control signals.
Present control signal to being provided according to this pitch conversion control module 280 and chord TCU transfer control unit 290, the concrete transposition method that chord generation unit 270 is carried out, contrast Figure 11 is illustrated.
Figure 11 also shows simultaneously that for polyphonic ring tone being made the situation of Ser.No. value 3 have the system of its chord.
In the chord generation unit 270, the transposition amount both that pitch conversion control module 280 and chord TCU transfer control unit 290 are supplied with is added on the numerical value of the tonality (former accent) that information center 210 provided, again divided by 12, with the numerical value of the remainder of the gained polyphonic ring tone after as transposition.At this moment, use still flat symbol of sharp symbol actually, according to shown in Figure 11 system with transposition amount (but also will add 3 in addition under the situation at ditty) rises semitone system or flats system decides increasing on the tonality of former accent.
And in Caraok device, show the character string of the lyrics, though wish to show the position that civilian sections falls the space that only may specify whole square en to determine in the character code always with delicate interval.And the lyrics that on display device, show because employed be bigger character, use the clearance space of perfect square piece hardly, but wish and can show with tiny interval less than the en block space.Therefore, purchase 8 fens blank spaces, 4 fens blank spaces and 2 fens blank spaces (en block gaps) three kinds, the branch of giving respectively is equipped with the code of each byte.And use these clearance spaces as required in combination, just can adopt various intervals to come display string.
