Description

  The present invention relates to a character processing device that expresses characters, and more particularly, to a character processing device that expresses characters written by hand on a screen, printed paper, or the like.

  Various types of fonts are incorporated in conventional word processing software. A “font” is a character shape used when a character is displayed or printed using a computer, and is also called a “typeface”. The word processor software can prepare a plurality of font types such as Gothic and Mincho in advance, and the user can use different fonts according to the type of the sentence, thereby improving the expression of the sentence.

  As a typical method of giving font data to a computer, a bitmap font that expresses the shape of a character as a collection of small square dots (dots) and an outline font that expresses the coordinates of a reference point and a collection of outlines Exists. These are selectively used depending on whether high-speed display processing or printing processing is important or whether aesthetics of characters is important. For example, while bitmap fonts can be processed at high speed, there is a drawback in that the shape of characters is lost when the font is enlarged or reduced. Outline fonts take time to display and print, but beautiful output is possible no matter how much they are enlarged or reduced. In recent years, with an increase in computer processing speed and higher resolution of printers, delays in processing time due to outline fonts have been reduced, and scenes in which outline fonts are preferred and used are increasing.

  For the purpose of simply transmitting information, fonts such as Gothic and Mincho are typically used. For example, in office documents, aesthetics by devising fonts are not emphasized, and since the main purpose is to transmit information, it is common practice to create documents in fonts such as Gothic and Mincho. On the other hand, brush fonts are often used for formal documents such as New Year's cards and greeting cards, and letters addressed to acquaintances. The brush typeface creates a powerful and sometimes refreshing atmosphere. In this way, by selecting an appropriate font according to the situation, the intention of the document creator is transmitted to the reader not only from the contents of the sentence but also from the entire sentence.

As a technique for devising such a font, for example, as disclosed in Patent Literature 1, the character is expressed by a handwritten character font, and as disclosed in Patent Literatures 2 and 3, the density of the font is adjusted. Something to do is proposed.
JP 2002-297115 A Japanese Patent Laid-Open No. 5-238066 JP 2004-61909 A

  For a long time, letters were written with a brush, but now there are few people who use a brush, especially for young people. Furthermore, with regard to fountain pens, there are fewer opportunities to use them than brushes, and the culture of the fountain pens is becoming obsolete. Letters with a fountain pen and brush can convey the warmth of the hand to the other party, creating a taste unique to handwriting. For example, the reader may imagine the psychological state of the writer and ponder his thoughts by looking at the blurring of ink or ink. This is a Japanese culture.

  As mentioned above, word processor software that provides brushstroke fonts has existed in the past, but as with other fonts such as Mincho and Gothic fonts, font data of the same size is prepared for each character. I'm just there. Therefore, compared to typical fonts such as the Mincho and Gothic fonts, it is possible to compose a aesthetic appearance with single characters, but these characters are each expressed uniformly in a square of a predetermined size. Therefore, it can be said that the aesthetics when viewed as a whole sentence are poor. When handwriting a sentence, the size of the letters is not all the same, and they are not exactly lined up. It can be said that handwritten documents have inflections, and not all of them are uniformly unified, but a handwritten feeling is generated by their sort of cluttered visual effects.

  Therefore, an object of the present invention is to provide a character processing device that creates a handwritten atmosphere.

  In order to solve the above problems, a character processing device according to an aspect of the present invention stores a receiving unit that receives character input from a user, an analysis unit that analyzes a part of speech of a word in the input character string, and font data And a allocating unit that assigns font data stored in the storage unit to the input character according to the part of speech of the analyzed word.

  According to this aspect, by assigning font data to characters input according to the part of speech, even if the same character is used, different font data can be used depending on how it is used. Thereby, the character processing apparatus of this aspect can improve the handwriting feeling of the document to create.

  The storage unit may hold a plurality of font data for the same character in one font type. The storage unit may hold font data representing a predetermined character string. Further, the storage unit may hold the font data as image data.

  The character processing device according to this aspect may further include an arrangement unit that sets a virtual reference line and determines the position of the character received by the reception unit using the reference line as a reference. Moreover, you may further provide the arrangement | positioning part which determines the space | interval between the words from the relationship of the part of speech of the word which follows before and after.

  It should be noted that any combination of the above-described constituent elements and a conversion of the expression of the present invention between a method, an apparatus, a system, a recording medium, a computer program, etc. are also effective as an aspect of the present invention.

  According to the present invention, it is possible to provide a character processing device that can create a handwritten atmosphere.

  FIG. 1 shows the configuration of a character processing apparatus according to an embodiment of the present invention. The character processing device 10 includes an input receiving unit 20, a preprocessing unit 22, a character string analysis unit 24, an allocation unit 26, an arrangement unit 28, a display conversion processing unit 30, a selection unit 32, and a storage unit 40. The storage unit 40 includes a dictionary data storage unit 42 and a font data storage unit 44. The character processing device 10 of this embodiment is a computer incorporating a word processor or software for a word processor, and has a function of changing the display mode of a character input by a user according to the part of speech of the word to which the character belongs. .

  The character processing function of the character processing apparatus 10 in the present embodiment is realized by a CPU, a memory, a program loaded in the memory, and the like, and here, functional blocks realized by their cooperation are depicted. The program may be built in the character processing apparatus 10 or supplied from the outside in a form stored in a recording medium. Moreover, the form supplied from the outside via a network may be taken. For example, the character processing function may be realized in the form of software that executes the functional blocks shown in FIG. At this time, for example, a product that realizes the character processing function of this embodiment is software for a word processor. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  The character processing device 10 is realized, for example, by starting word processing software on a computer. The input receiving unit 20 receives input from the user. The user performs input using an input interface such as a keyboard or a mouse. When the word processor software of the present embodiment is activated, for example, a plurality of font type selection screens are displayed on the monitor.

  Multiple types of font types may be created separately for men and women. Generally, men and women have different writing pressures, and handwritten characters often determine whether the writer is male or female. It is often said that "a book represents a person", but handwritten characters represent not only a person's gender but also an inner personality element. It is easy for anyone who has a brush to understand that a brush is used. The character processing apparatus 10 according to the present embodiment can output a text as if it were handwritten while being input on a computer. For this reason, the font data storage unit 44 of this embodiment prepares various types of fountain pen font types in order to expand the user's choices. In addition, the character processing apparatus 10 of a present Example may prepare not only a fountain calligraphy font but a writing brush font and other typefaces.

  The user looks at the font type selection screen displayed on the monitor, and selects one of the favorite font types using the input interface. For example, a plurality of buttons for font type selection are prepared on the selection screen, and a font type selection instruction is made by selecting one of the buttons. When the input reception unit 20 receives a user's font type selection instruction, the selection unit 32 selects a font file to be used from among a plurality of font files stored in the font data storage unit 44. The font file is a file holding font type font data, and there are as many font types as there are font types. Each font type has some subject, such as a strong typeface, a thin typeface, a typeface with a faint appearance, a typeface with a feeling of movement, and the corresponding font file has font data according to the subject. Created.

  Each of these typefaces may be created by reading a character actually handwritten with a fountain pen with a scanner when creating the typeface. At this time, what represents the font type to the user may be the name of the person who became the model of the font data, and the name of the writing instrument such as a fountain pen or brush, or the subject of the font type as described above. There may be. A plurality of types of font files may be prepared as defaults, and the user himself / herself may create font data handwritten by himself as a font file. In addition, font data created by handwriting by the user may be incorporated into a font file prepared by default. The font data storage unit 44 stores font data as image data. The font data storage unit 44 holds image data of at least all hiragana characters one by one. Advances in printing technology have made it possible to reproduce fine shades even on home printers. By using font data as image data obtained by scanning handwritten characters written with a fountain pen at high resolution, the document obtained by printing reproduces the shading and faintness of the fountain pen. As described above, in this embodiment, it is assumed that the font data is prepared as image data. However, for example, the font data can be prepared as an outline font or a bitmap font as in the past. It can also be expressed as a function. Further, the font data may be prepared as a combination of information for specifying the outline font and information for specifying the character size and character modification type.

  When the selection unit 32 selects a font type, only the font data of the selected font type is used in the subsequent processing. Note that it is possible to change the font type in the middle of text input, but in this case, it gives the impression that a plurality of people cooperated to handwrite a single document.

  The font data storage unit 44 holds a plurality of font data for the same character in one font type. For example, for hiragana “no”, a large size and a small size are prepared. Of course, not only the difference in size but also a horizontally long font data or a vertically long font data such as those having different top / bottom / left / right ratios may be prepared. Note that the font data storage unit 44 does not need to hold a plurality of font data for all characters, and may hold a plurality of font data for at least some characters.

  The font data storage unit 44 holds font data representing a predetermined character string. For example, in the case of outputting a character string “buzzy”, the font data storage unit 44 holds “bo”, “n”, “ya”, “ri” as image data of one character. In addition to the image data, the character string “blurred” may be held as one image data. As a result, the character processing apparatus 10 can output not only the character string “blurred” by arranging the four image data, but also can output the character string “blurred” with one image data.

  In order to reduce the amount of data stored in the font data storage unit 44, it is preferable that the predetermined character string expressed by one image data is limited to one frequently used as a series of character strings. When a person writes a sentence, one word tends to be written at a stretch. Character strings written at once are connected to each other, and it can be inferred from the readers that the connected characters constitute one meaning. In order to realize such an effect, it is preferable that the font data storage unit 44 holds font data expressed by connecting characters for a predetermined character string including a plurality of characters.

  After the font type is selected, the preprocessing unit 22 displays a character input screen on the monitor. The input screen may be similar to that found in existing word processing software. When the cursor blinks at the input position on the screen and the user enters characters, the cursor moves in the line direction and the cursor blinks. Input characters are displayed from the location.

  The input receiving unit 20 receives a character input from the user, and the preprocessing unit 22 displays the characters input on the screen in hiragana. At this time, the preprocessing unit 22 may display characters input using font data such as Mincho, instead of using the font file selected in the font data storage unit 44. When a conversion key provided as an input interface of the character processing device 10 is pressed, the input character is converted into corresponding font data in the font data storage unit 44. This processing is basically the same as the processing in existing word processing software. Therefore, until the user presses the conversion key, the input hiragana characters are arranged in rows on the screen in an unconverted state.

  FIG. 2 shows an example of input from the user and displayed on the screen by the preprocessing unit 22. The input accepting unit 20 accepts an input such as “slowly and swiftly” from the user, and the preprocessing unit 22 displays a character string on the screen. In FIG. 2, characters are displayed in a Mincho font. A dotted line attached to the side of the sentence indicates that the input character is not converted.

  In FIG. 2, characters are displayed in Mincho font, but characters may be displayed on the screen using hiragana font data stored in the font data storage unit 44. The display in the Mincho style is to reduce the amount of data processing. If the character processing device 10 is composed of high-spec hardware, the character data stored in the font data storage unit 44 is displayed. Screen display may be performed using image data (font data).

  When the user presses the conversion button on the keyboard, the input receiving unit 20 receives the pressing, and the character string analyzing unit 24 performs morpheme analysis that divides a sentence written in a natural language into morpheme strings. Specifically, the character string analysis unit 24 performs a “wakachi writing” process for discriminating word boundaries and analyzes the part of speech. First, by the wakachi writing process, the input character string “slowly and sizzling” is divided into the words “slowly”, “to”, “shi”, “ta”, “mezame”, “.”. In this embodiment, the punctuation mark is also processed as a word.

  The character string analysis unit 24 analyzes the part of speech in the input character string composed of a plurality of characters. The writing process and the part-of-speech analysis may be executed simultaneously. That is, when the writing process is performed, a process of assigning parts of speech to the divided words may be performed. Morphological analysis is performed by classifying words according to grammatical functions and forms. As part-of-speech classification methods, morphological classification method, semantic classification method, syntactic classification method, etc. are considered. In this example, morphological analysis is performed by using an existing grammar analysis algorithm. It may be broken.

  In order to realize the analysis function of the character string analysis unit 24, the dictionary data storage unit 42 stores dictionary data holding knowledge of Japanese grammar and a word list with parts of speech. Further, the dictionary data storage unit 42 holds a conversion correspondence table between reading (kana) and kanji. The character string analysis unit 24 obtains the part of speech of the word and further converts the hiragana sentence into a kanji-kana mixed sentence by referring to the dictionary and the conversion correspondence table stored in the dictionary data storage unit 42. In this example, the kana character string “Awake” is converted to “Awake”.

  FIG. 3 shows a part of speech analysis result by the character string analysis unit 24. When the part-of-speech analysis of “slowly and savory shark” is performed, the words that have been processed for writing are divided into corresponding parts of speech.

  FIG. 4 shows an example sentence described in the Mincho style, which is one of the conventional font types. This example sentence is a character processed by conventional word processing software. In general, the Mincho style is often used for formal, hard documents such as business documents. In conventional word processing software, all characters are output in the same size, and one character is output in a predetermined cell, and the character spacing is set equal.

  FIG. 5 shows the example sentence shown in FIG. 4 described in a brush typeface, which is one of the conventional font types. Writing characters in a brush font can create a softer atmosphere than Mincho and Gothic. However, all characters are output in the same size, and the character spacing is set equal.

  As shown in FIGS. 4 and 5, when characters are output in the conventional font type, the size of the characters and the character spacing are all the same, so that the writer's feelings are not easily transmitted to the reader. In the case of a brushstroke body, there is certainly an effect that makes the atmosphere slightly softer than in the Mincho style, but it cannot be denied that it can still be regarded as just a list of characters. Therefore, the character processing apparatus 10 according to the present embodiment provides a character processing function that can give an atmosphere like a handwritten sentence.

  Returning to FIG. 1, the assigning unit 26 assigns the font data stored in the font data storage unit 44 to the word according to the part of speech of the word analyzed by the character string analyzing unit 24. The font data storage unit 44 holds a plurality of font data for the same character in one font type. For example, a plurality of font data is held as image data for the hiragana character “no”.

  FIG. 6 shows an example of font data stored in the font data storage unit 44. Here, a state in which the font data storage unit 44 holds a plurality of font data for the same character “NO” is shown. Note that the font data storage unit 44 does not need to hold a plurality of font data for all characters, and only needs to hold a plurality of font data for at least specific characters. In addition, if there is a margin in the performance of hardware such as a hard disk, a plurality of font data is retained for all characters, the font data is used properly, and the sense of unity of the text is intentionally destroyed, thereby creating a handwritten atmosphere Can be created further.

  The font data storage unit 44 stores the font data in association with the part of speech of the word including the character. When a word is composed of one character, the part of speech to be associated indicates the part of speech of the word expressed by the character itself, and when the word is composed of a plurality of characters, the part of speech to be associated is the character Indicates the part of speech of a word that contains For example, although the word “free” is an adverb, the assigning unit 26 assigns font data stored in association with the adverb to “no” included in the word “free”.

  In the figure, two types of font data, display data for display on the screen and print data for printing, are set. In the example of FIG. 6, the display data and the print data are composed of the same image data, but they may be different. Since the printing resolution is generally higher than the resolution displayed on the screen, for example, the font data for printing may be created with image data having a higher resolution than the font data for display. If display data and print data are not prepared separately, only one font data need be prepared.

  In the present embodiment, the font data storage unit 44 holds large font data and small font data for the character “NO” in the selected font type. Large font data is associated with verbs, adjectives, nouns, conjunctions, adverbs, and conjunctions. Small font data is associated with particles and auxiliary verbs. Thus, in this embodiment, two types of font data are associated with one of independent words or attached words. An independent word is a part of speech that can constitute a phrase alone, and an accessory word is a part of speech that cannot constitute a phrase alone. Independent words and ancillary words can be further classified according to whether or not they are used, and different font data may be associated depending on whether or not they are used.

  In this embodiment, the font data and the part of speech are associated with each other based on some policies regarding character processing. For example, under the policy that independent words play an important role in sentences, characters contained in parts of speech such as independent words, that is, verbs, adjectives, nouns, conjunctions, adverbs, and conjunctions, are expressed in large font data. On the other hand, under the policy that an adjunct does not play a relatively important role in a sentence, the characters included in the part of speech such as an adjunct, that is, a particle and an auxiliary verb, are expressed by small font data. The font data allocation method may be further subdivided according to the part of speech. For example, font data allocation may be set according to whether or not it is used. Furthermore, a plurality (three or more types) of font data may be prepared for each part of speech, and font data allocation may be set.

  In FIG. 6, in the data item “arrangement position”, the arrangement position in the line of the font data is set. In the character processing apparatus 10 of the present embodiment, the text is input to a line set in the screen or on the printing paper. In this embodiment, a line for arranging characters is set regardless of whether or not it is displayed. In the vertical writing, the line is arranged in the vertical direction, and in the horizontal writing, the line in the horizontal direction is set. The characters are arranged side by side. When the arrangement position is set to “center”, the character is arranged at the center in the line. Further, in the case where the arrangement is arranged in any of the left and right directions from the center of the row, the arrangement position is set to “right 20%” and “left 15%”. Here,% indicates a shift amount from the center of the row to the right end or the left end. For example, if it is 50% to the right, the arrangement position is located in the middle between the row center line and the right end.

  The allocation unit 26 refers to the font file stored in the font data storage unit 44 and allocates font data to the input character. For example, referring to the part-of-speech analysis result shown in FIG. 3, since the part-of-speech of the word “freedom” is an adverb, the allocating unit 26 uses the large and small fonts shown in FIG. Of the data, the larger “no” is assigned.

  FIG. 7 shows a part of speech analysis result by the character string analysis unit 24. When the part-of-speech analysis of “Awakening in the morning that is blurred in the direction of the head” shown in the third line of FIG. 4 or FIG. 5 is performed, the part-of-speech of the word that has been processed is set.

  In the third line of the example sentence, three “no” appear, but each part of speech is a particle. Therefore, the assigning unit 26 refers to the font file stored in the font data storage unit 44 and assigns the smaller “no” of the font data shown in FIG. 6 to these three “no” s. . As described above, the assigning unit 26 assigns font data according to the part of speech of the analyzed word, and can change the shape of the character according to the part of speech even for the same character.

  The arrangement unit 28 determines the arrangement position of the font data allocated by the allocation unit 26. At this time, the arrangement unit 28 refers to the data item “arrangement position” of the font file shown in FIG. 6 and determines the character arrangement position. In the font file, by setting the "placement position" not only at the center of the line but also at a position that touches the left and right of the line, all the characters are placed in the left and right direction instead of neatly arranged. This makes it possible to create a sentence with a handwritten atmosphere.

The placement unit 28 may set a virtual reference line and determine the position of the character with reference to the reference line.
FIG. 8 shows a virtual reference line set in a row. In FIG. 8, a row is an area surrounded by two solid lines, and a reference line set in the row is indicated by a dotted line. In the example of FIG. 8, the reference line takes the form of a straight line as the center line of the row.

  The placement unit 28 determines the position of the character with reference to this reference line. The placement unit 28 places the characters so that the center of gravity position of the placed characters is on the reference line. The position of the center of gravity of the character is obtained in advance and is preferably stored in the font data storage unit 44 as an attribute of the font data. There are various ways of obtaining the center of gravity position, but the simplest way is to calculate the center position from the vertical and horizontal lengths to obtain the center of gravity position. Further, the center of gravity position may be obtained by considering the center point of the density distribution in consideration of the thickness of the line element. At this time, it is preferable that the center-of-gravity position is obtained so as to be the apparent center position. As described above, various methods can be used as a method of obtaining the center of gravity position. In this embodiment, the center of gravity position is set in advance using a known center-of-gravity position search method.

  The arrangement unit 28 arranges the barycentric position of the font data on the reference line, so that a basic line of the character string can be set. The arrangement position set in the font file may be applied to the reference line. Thereby, it is possible to disperse the character arrangement in the left-right direction with respect to the reference line.

  The placement unit 28 sets the character spacing in one word to a predetermined value. This predetermined value is set to a small interval such as 0 mm or 0.1 mm, for example, to indicate that a plurality of characters is a set of one lump. On the other hand, the arrangement unit 28 sets an interval between words in the separation between words. Thereby, the position of the character in the line is determined. Specifically, the arrangement unit 28 sets the interval according to the part of speech of the preceding and following words.

  For example, when a noun follows a verb or auxiliary verb, the character string before the noun often modifies the noun. For this reason, the interval between the verb or auxiliary verb and the noun is increased to indicate that the character string before the noun is a noun modifier. For example, the separation between words at this time is set to a relatively large predetermined value such as 0.5 mm. In addition, it is preferable that the space | interval between words in this case is set to a value wider than the character space | interval in a word.

  An example in which an auxiliary verb and a noun are followed corresponds to a break between “slowly” and “awake” in the first line of the example sentences shown in FIGS. Similarly, when an adverb follows an adverb, the character string before the adverb often has a meaning different from the subsequent character string. This corresponds to a break between “eyelid” and “still” in the second line of the example sentence. The same applies when a noun follows a particle. This corresponds to a break between “In the corner” and “Buzzy” in the third line of the example sentence. When there is such a special relationship, the interval between words is set to a wide value, and the breaks between other words are set to a narrower value. The arrangement unit 28 holds in advance the conditions of parts of speech before and after that for increasing the interval between words. Thus, by setting the space | interval of words, a reader becomes easy to take a meaning and can improve a handwriting feeling.

  In addition, when the condition of the part of speech before and after for widening the space | interval of words is set, when this condition is satisfied, you may always widen a word space | interval, but this determination may be made at random. For example, the probability of whether or not to increase the word interval may be set in advance, and when the condition is satisfied, it may be determined whether or not to increase the word interval by performing a lottery with this probability.

  It should be noted that, when the word interval is widened, it may be visually unpreferable if there are a large number or a small number of wide word intervals compared to the adjacent sentence. Therefore, for example, the arrangement unit 28 may have an upper limit of a portion where the word interval is widened among the predetermined number of characters. For example, if there are places where the word spacing is wide at 6 places out of 15 characters, it may be possible to give the impression of being extended as a whole. For this reason, the arrangement unit 28 may set an upper limit so that the word interval is 5 or less in 15 characters. If there are 6 or more locations that satisfy the upper limit for expanding the interval, the 6 locations are selected by lottery or the like so as to be within 5 locations. According to the character processing function of the present embodiment, since the characters are not configured to have the same size, for example, instead of looking at the number of characters, it may be determined by the length of the character string.

  The display conversion processing unit 30 arranges the character whose arrangement position is determined by the arrangement unit 28 on the screen. Thereby, the display in a screen can be converted into the character of a fountain pen font. Note that display data is assigned by the assigning unit 26 when displayed on the screen, and print data is assigned when printing.

  FIG. 9 shows an example sentence that is processed by the character processing apparatus 10 and displayed on the screen. According to the character processing device 10 of the present embodiment, by changing the font data of the character according to the part of speech, it is possible to obtain an output with a sense of handwriting rather than arranging all the characters in an inorganic material. When “NO” in the first row is compared with “NO” in the third row, it is understood that “NO” in the first row is displayed larger than “NO” in the third row. In addition, it is understood that not all characters are arranged according to the center line, and some characters are arranged at positions shifted in the left-right direction. In the embodiment, the character “no” has been described in particular, but the same applies to other characters. By preparing a plurality of font data for various characters, it is not a uniform sentence style but a feeling of feeling. It is possible to automatically create a sentence that has been stored.

  FIG. 10 shows another example of a virtual reference line set in a row. In FIG. 10, a row is an area surrounded by two solid lines, and a reference line set in the row is indicated by a dotted line. As illustrated, the reference line is set as a wavy line in the row.

  In general, when a person writes a sentence, it is rare to write a character in a straight line, and it is often bent or tilted. For example, even when two straight lines indicating lines are drawn on the stationery, people usually have some hesitation about writing. Or in horizontal writing, the sentence goes up to the right. For example, a person's attitude of writing letters or how to hold a brush affects such things, and as a result, a tasty document is created. The inventor paid attention to this point and decided to improve the handwriting feeling by arranging characters with some rhythm rather than simply arranging characters linearly.

  The placement unit 28 determines the character placement position so that the center of gravity of each character overlaps the wavy reference line shown in FIG. 10, thereby creating a sentence in which the characters are moderately scattered in the left-right direction. As a result, it is possible to create a cluttered atmosphere in a certain sense like a document created by handwriting, not a text in which characters are arranged in an orderly manner, and the handwriting feeling can be improved. Note that the reference line is not limited to a wavy line, and may be a straight line that connects, for example, from the upper right to the lower left of the row. In this case, a sentence tilted to the right is created. The above is the case of vertical writing, but the same applies to the case of horizontal writing. As described above, a straight line or a curve different from the center line is set as a reference line, and the character placement position is determined so that the center of gravity of each character is on the reference line, whereby a sentence with a high handwriting feeling can be created.

  FIG. 11 shows another example of font data stored in the font data storage unit 44. Here, a state in which the font data storage unit 44 holds font data for a predetermined character string made up of a plurality of characters is shown. The predetermined character string may be composed of a plurality of parts of speech as well as a word composed of one part of speech. In the example shown in FIG. 11, the character string “bobby” is a single noun, but the character string “to” is composed of three parts of speech: the particle “to”, the verb “shi”, and the auxiliary verb “ta”. Yes. The font data storage unit 44 holds, for example, a character string frequently appearing in a sentence as one font data in advance.

  In handwritten text, frequently appearing character strings are often written as continuous characters. This is partly due to the fact that handwriting is memorized by writing well. Some character strings are easy to write as continuous characters because of the relationship between the writing start position and the writing end position. Such a character string is scribbled and characters are written continuously. Therefore, the font data storage unit 44 holds a predetermined character string as font data created as a continuous character, and the assigning unit 26 assigns the font data to the input character string, whereby the momentum of the brush is obtained. You can create sentences that make you feel. In the example of the font file in FIG. 11, only the hiragana character string is shown, but it goes without saying that it may be a kanji character string or a kana-kanji mixed character string. In the example sentence shown in FIG. 9, font data of this character string is assigned.

  Note that the font data of the character string is not limited to continuous characters. In consideration of the amount of data stored in the font data storage unit 44, it is preferable to limit the number of font data of the character string. However, if the storage capacity of the font data storage unit 44 is large, the font data of the character string is You may have many. In this case, font data of a character string may be created for a general word. Since the font data storage unit 44 stores all the character data of hiragana, even if the character string of a certain word is not stored, it is possible to represent the word at least in hiragana. is there.

  A weight for selection may be set in the font data of the character string. For example, it is assumed that three types of font data “awake”, “awake”, and “awake” are prepared for the noun “awake”. Of the three types of font data, when the weights are weighted in the order of “awake,“ awake ”,“ awake ”, the allocation unit 26 gives priority to the“ awake ”having a higher weight over the word“ awake ”. assign. This weight may be set as an allocation priority. The priority order is preferably set in the order of more tasteful font data. The priority is set by default by the font creator or the creator of the character processing function of the character processing apparatus 10 (for example, the creator of the software). The user is presented with choices, and when the user selects other font data, the font data is assigned. At this time, it is preferable that the priority order set by default changes, and the priority order of the selected font data becomes the first. As described above, by changing the priority order of the font data, it is possible to assign the font data reflecting the user's preference.

  Further, the font data storage unit 44 stores font data that expresses “flowing condition”, “smearing condition”, and “smearing condition” step by step for each character, and the allocating unit 26 sets them in a predetermined ratio. You may choose according to.

  FIG. 12 is a flowchart for realizing character processing in this embodiment. In this character processing flow, it is assumed that the font type of the font data storage unit 44 has been selected. The input receiving unit 20 receives a character input from the user (S10). When the user presses the conversion key while inputting a plurality of characters, the input reception unit 20 receives the conversion instruction (S12). The character string analysis unit 24 performs morphological analysis on the part of speech of the word in the input character string (S14), and performs kana-kanji conversion processing (S16). Note that the morphological analysis and kana-kanji conversion processing are executed as internal processing of the character processing apparatus 10, and at this time, the processing results do not appear on the screen.

  In the input character string, the assignment unit 26 determines whether or not a predetermined character string exists (S18). The predetermined character string is a character string registered as font data in the font data storage unit 44. When the predetermined character string exists (Y in S18), the assigning unit 26 assigns the character string font data held in the font data storage unit 44 to the character string (S20). On the other hand, for characters not included in the predetermined character string (N in S18), the assigning unit 26 assigns character font data to the input character based on the part of speech analyzed by the morphological analysis (S22).

  Subsequently, the placement unit 28 determines the position where the character is placed (S24). When the positions of all the characters are determined, the display conversion processing unit 30 places the assigned font data at the determined positions (S26), and generates a document with a high handwriting feeling.

  FIG. 13 is a flowchart of the character position determination process shown in S24 of FIG. First, the placement unit 28 acquires part-of-speech of the previous and subsequent words in the character string (S30). When there is a predetermined relationship between the parts of speech of the preceding and following words (Y in S32), the placement unit 28 sets a wide word interval (S34). On the other hand, when there is no predetermined relationship between the parts of speech of the preceding and following words (N in S32), the word interval is set narrow (S36). Note that the character spacing in the word may be preset as a fixed value. Further, the arrangement unit 28 reads out the arrangement position data included in the font file of the font data storage unit 44 (S38), and determines the character position using the reference line set in the line (S40). Specifically, the character position is provisionally determined so that the center of gravity of each character overlaps the reference line, and the font data is moved from the provisionally determined position in the direction indicated by the arrangement position data. For example, for a character whose arrangement position data is set to “center”, it is determined at the provisional position of the font data. For a character whose arrangement position data is set to “10% right”, the font is used. The position of the center of gravity of the data is shifted to the right by 10% of the half width of the row. As described above, the position of the character is determined.

  In the above, this invention was demonstrated based on the Example. These embodiments are exemplifications, and it is understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are within the scope of the present invention. is there.

  In the present embodiment, as shown in FIG. 2, the case has been described in which character processing is performed on a single input sentence, but it is also possible to perform character processing in units of clauses shorter than one sentence. The character processing is triggered by the user pressing the conversion key. Therefore, the character processing is executed for the input character string at the timing when the input receiving unit 20 receives the conversion instruction.

  The arrangement unit 28 determines the interval between words based on the relationship between the parts of speech of the preceding and following words. When determining the interval, the arrangement unit 28 considers the relationship with the immediately preceding word that has already undergone character processing. By referring to the part of speech of a word that has already undergone character processing, the placement unit 28 can appropriately set the interval between words.

  The allocation unit 26 may perform font data allocation processing by enlarging / reducing font data. By having the font data enlargement / reduction function, it is not necessary to provide the font data storage unit 44 with the enlarged font data and the reduced font data.

  Further, when all the character processing is completed, the document is completed, but the allocation unit 26 may re-execute the font data allocation processing at that time. For example, an instruction to re-execute the allocation process is input from the user, and the allocation unit 26 receives the instruction and executes the font data allocation process. At this time, for example, when font data with a low priority set in advance as a default is assigned, it may be suggested to the user that the font data can be changed to one with a higher priority. For example, it is possible to give suggestions to the user by changing the color of the character and displaying it.

  Further, when all the character processing is completed, the character string analysis unit 24 may perform the part of speech analysis processing again. In this case, an instruction for re-executing the part-of-speech analysis process is input from the user, and the character string analysis unit 24 receives the instruction and analyzes the character string.

  In the embodiment, the description has mainly been made on characters. However, the arrangement unit 28 further has a function of setting the positions of symbols such as punctuation marks and parentheses. For example, the placement unit 28 may place the symbols at random positions in the left-right direction. In particular, the punctuation marks are not necessarily placed on the right side, but the handwriting feeling can be improved by placing them near the center or near the left side.

  In the embodiment, the user selects the font type. For example, the font data is set to a value obtained by analogly evaluating the character atmosphere, and the user does not select the font type. By specifying a numerical range for analog evaluation, font data may be extracted from the font data storage unit 44 as a candidate for character allocation. The analog evaluation is performed by a font creator or a software creator, and the character assignment process may be executed based on the evaluation value.

  Moreover, although the character processing apparatus 10 of the present embodiment has been described as a stand-alone terminal, it may be constructed as a client-server system via a network. In this case, the user inputs a sentence from the client terminal and transmits it to the server, and the server collectively performs character processing on the transmitted sentences. This character processing function corresponds to that described above. This eliminates the need for the client terminal to have a character processing function. In this case, the character-processed result is transmitted from the server, and the client terminal can display or print it on the screen.
