Description

How to apply kerning for Hangeul {METHOD FOR APPLYING KERNING TO HANGEUL}

The present invention relates to a method of applying kerning for Hangul, and more specifically, the character spacing is different according to the entered characters, based on the data stored in advance, without applying the same character spacing to the input Hangul. By setting it, it relates to a method of making an input word or sentence visually smooth, thereby improving overall readability.

In the case of Hangeul, letters are formed by a combination of consonants and vowels, and accordingly, unlike English, where alphabets are listed, various types of letters exist by combining various consonants and vowels.

Since these various types of letters are listed and input as words or sentences, the letter or letter spacing is generally input at the same fixed value interval.

However, if characters or character spacings are input with the same fixed value, there is a disadvantage in that the character spacing is visually wide or narrow depending on the shape of the characters, making it uncomfortable to read or not visually smooth.

Accordingly, in order to make a word or sentence look visually smooth when a letter is input, the demand for developing a kerning technique to correct the letter spacing for each letter combination to improve readability is gradually increasing. There is an urgent situation to solve.

The present invention is to solve the above-mentioned problems of the prior art, and does not apply the same letter spacing to all of the input Hangul characters, but by setting the letter spacing differently according to the external shape or shape of the letter, input The purpose is to make the words or sentences that appear to be visually smooth.

The objects of the present invention are not limited to the objects mentioned above, and other objects not mentioned will be clearly understood from the following description.

A method of applying kerning for Hangul is provided.

The step (a) may include: (a0) generating group data by performing grouping of letters based on a font frame that is an external shape of the letter for each of the plurality of Hangul letters; (a1) pairing a plurality of grouped groups to generate a plurality of group pairs; And (a2) generating kerning data by setting a kerning value for each of the plurality of group pairs.

The step (b) may include determining, when the first letter and the second letter are input, a group including the first letter and the second letter, respectively, based on the stored group data. .

In step (b), if it is determined that the group including the first letter is the first group, and the group including the second letter is the second group, based on the kerning data, the first group and the first group And applying the kerning value corresponding to the pair of 2 groups to the interval between the first letter and the second letter to process the kerning.

The step (b) may include, before applying the kerning value, modifying the character width for each of the first character and the second character to a variable width based on previously stored variable width data. .

In the variable width data, it is assumed that a variable width set value is matched to each of a plurality of characters, and the variable width set value is set to different values according to a font frame that is an external shape of the letter. .

On the other hand, according to another embodiment of the present invention, a kerning data generation unit for generating kerning data for applying kerning to a plurality of Hangul characters consisting of a combination of consonants and vowels; And a kerning processing unit that processes kerning by applying a kerning value to an interval between the first and second letters based on the generated kerning data when the first and second letters, which are a plurality of Hangul characters, are input.

Hereinafter, the present invention will be described with reference to the accompanying drawings. However, the present invention may be implemented in various different forms, and thus is not limited to the embodiments described herein. In addition, in order to clearly describe the present invention in the drawings, parts irrelevant to the description are omitted, and like reference numerals are assigned to similar parts throughout the specification.

Throughout the specification, when a part is "connected" to another part, this includes not only "directly connected" but also "indirectly connected" with another member in between. . Also, when a part “includes” a certain component, this means that other components may be further provided instead of excluding other components, unless otherwise stated.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a user terminal 100 according to an embodiment of the present invention.

Referring to FIG. 1, the user terminal 100 according to an embodiment of the present invention may include a kerning data generation unit 110 and a kerning processing unit 120.

The user terminal 100 includes all kinds of handheld-based wireless communication devices equipped with a touch screen panel, such as a mobile phone, smart phone, PDA (Personal Digital Assistant), PMP (Portable Multimedia Player), tablet PC, etc. In addition, it can also include devices that have a foundation on which to install and run applications, such as desktop PCs, tablet PCs, laptop PCs, and IPTVs that include set-top boxes.

The user terminal 100 may be pre-installed with one or more document creation-related programs equipped with a text writing function according to input of Korean characters or special characters, and stored in the memory of the user terminal 100.

The user terminal 100 may be implemented as a terminal, such as a computer operating through a computer program for realizing the functions described herein.

The kerning data generation unit 110 may group all Hangul characters and special characters according to a font frame for generating kerning data for Korean characters and special characters. At this time, the font frame means that the external form of a single letter is expressed in a specific shape.

For example, referring to FIG. 4, the kerning data generation unit 110 may include “almost”, “west”, “low”, “off”, “shh”, “lower”, “ki”, and “poem” "," Ji "is the appearance of the letter corresponds to the second font frame 402, so it is grouped into a second group, and" oh "," yo "," woo "," yu "," uh " Since the external shape of the letter corresponds to the third font frame 403, it can be grouped into a third group.

Accordingly, as illustrated in FIGS. 6 to 8, the kerning data generation unit 110 may group all Hangul characters and special characters, and store grouped group data in a database (not shown).

The kerning data generation unit 110 performs pairing for a group that is determined to need to be corrected for character spacing in order to be visually smooth when neighboring each other by input based on the grouped characters or character groups. It can be done.

For example, referring to FIG. 4, when the kerning data generation unit 110 is adjacent to each other with 9 characters included in the second group and 5 characters included in the third group, the correction for the character spacing If it is determined that this is necessary, the second group and the third group can be paired.

The kerning data generation unit 110 may generate kerning data by setting a kerning value for each paired pair of groups, and the generated kerning data may be stored in a database (not shown). In this regard, embodiments of the present invention are as shown in FIGS. 9 to 18.

For example, as illustrated in FIG. 14, the kerning data generation unit 110 sets the kerning value of “-30” for the group pair “@ 10” which is the tenth group and the group “@ 21” which is the 21st group. Can be.

In this case, the set kerning value may be a value for a letter spacing determined to be visually smooth when letters included in the group pair are adjacent to each other.

When a Korean character or special character is input, the kerning processor 120 may determine a group including each of the input characters or characters.

For example, assuming that the input character is “baby”, the kerning processing unit 120 may determine a group including the characters “a” and “a”, respectively. Referring to FIG. 6 as an example, kerning The processor 120 may determine that the letters “A” and “A” are included in the “@ 10” group and the “@ 10_1” group, respectively, based on group data stored in advance in a database (not shown). .

The kerning processing unit 120 may modify the character width for each input character based on the variable width data before applying kerning to the input word or sentence. At this time, the variable-width data refers to data in which variable-value values preset for each character group are listed for a plurality of characters or characters, which may be stored in a database (not shown).

For example, referring to FIG. 3, when the word “coarse” is input, the kerning processing unit 120 writes “920” for the text “almost” based on the variable width data 301 The self-destruction can be modified to a variable width of "900", and the letter "pa" can be modified to a variable width of "950".

The kerning processing unit 120 may apply the kerning value for each group pair based on the determined group information for each input letter after correcting the letter width, so that the input word or sentence is kerning.

For example, when the group data illustrated in FIG. 6 and the kerning data illustrated in FIGS. 9 to 15 are described with reference to an embodiment, when “Agazaja” is input, letters “A” and “A” adjacent to each other are For the letter spacing of ", the kerning value of the 10th group" @ 10 "with" A "and the 10th group" @ 10_1 "with" A "pair is set to" -20 "on the kerning data. Bar, the kerning processing unit 120 can apply a kerning value of "-20" between the letters "A" and "A" to kerning, and then the letters "A" and "S" adjacent to each other and For "four" and "ruler", the kerning value of the 10_1 group "@ 10_1" containing "a" and the 10_2 group "@ 10_2" pair containing "a" is "-30" on the kerning data. Is set, and the kerning value of the 10_2 group "@ 10_2" containing "four" and the 10 @ 3 group "@ 10_3" containing "ru" pair is also set to "-30" on the kerning data. , "A" and "four" Kerning may be applied by applying a kerning value of "-30" between letters and between "four" and "letter" letters. On the other hand, with respect to the letter spacing of "Rules" and "B", the kerning value of the 10_3 group "@ 10_3" containing "Rule" and the 26_9 group "@ 26_9" Pair containing "R" is kerning data. In this case, in this case, the kerning processing unit 120 may maintain the default value of the preset letter spacing without performing a separate kerning process.

2 is a flowchart illustrating a process in which kerning data is generated and kerning is processed for Hangul input by a user according to an embodiment of the present invention.

First, grouping can be performed on all Hangul characters that can be formed by a combination of vowels and consonants (S201). At this time, grouping may be performed based on a font frame formed according to the appearance of Hangul characters, and group data may be generated accordingly. Group data may be stored in a database (not shown) of the user terminal 100.

According to an embodiment of the present invention, when performing grouping, grouping for special characters as well as Hangul characters may also be performed.

For example, when the embodiment illustrated in FIG. 4 is described as an example, the letters “O”, “Yo”, “Ru”, “U”, and “U” have the appearance of letters in the third font frame 403. Judging as applicable, it can be grouped into a third group, and the letters "off", "cuck", "ki", "write", "?", "Seed", "ze", "쪄", "seed" "Is determined to correspond to the sixth font frame 406, it may be grouped into a sixth group.

When grouping is completed, pairing for a plurality of groups may be performed (S202). At this time, group pairing may be performed only for a group pair that determines that character spacing adjustment is necessary when each letter of a group pair in which two groups of a plurality of groups are paired with each other.

That is, when the characters included in the first group and the characters included in the second group are input to be adjacent to each other, if it is determined that the character spacing needs to be adjusted, the first group and the second group may be paired.

When the group pairing is completed, it is determined that the character spacing needs to be adjusted, and kerning data can be generated by setting a kerning value for each grouped group pair (S203). Examples of kerning data thus generated are illustrated in FIGS. 9 to 18.

The kerning value set for each of the group pairs may be a value that is appropriately corrected so that the gap between the letters of the two groups is visually smooth when applying kerning, and may be a value that is differently set according to the group pair.

In addition, the generated kerning data may be stored in the database of the user terminal 100.

Thereafter, when a character or character is input by the user (S204), the user terminal 100 may search for and determine a group to which each input character or character is applied (S205). At this time, the user terminal 100 may perform a search for the input character or character based on group data stored in advance in a database (not shown).

Before the kerning process, the user terminal 100 may modify the character width of the input character or character from a fixed width to a variable width (S206). At this time, the text width correction may be performed based on preset variable width data.

The variable width data is data in which variable width values are set for each of a plurality of characters or characters, and the variable width values may be set differently for each group according to the grouped group.

When the character width modification is completed, the user terminal 100 may complete the kerning process by applying kerning values for a plurality of characters or characters input based on kerning data stored in advance (S207).

Applying the kerning value is to apply the kerning value set in the kerning data to correspond to the group pair corresponding to the letters or characters adjacent to each other based on the determined group information corresponding to each of the input characters or characters. Can be.

For example, when it is assumed that the input word is "baby", when the embodiment of the group data shown in FIG. 6 and the embodiment of the kerning data shown in FIG. 9 are described as examples, the letter "a" is included. The group is the "@ 10" group, and the group containing the letter "A" is the "@ 10_1" group. For the letter spacing of the input letters "A" and "A", the "@ 10" group and the " The kerning value can be processed by applying the kerning value "-20" corresponding to the @ 10_1 "group pair.

As the words or sentences entered as described above are automatically kerned through the user terminal 100, the words or sentences appear visually smooth compared to words or sentences entered at the same character interval without separate kerning processing, and accordingly, the corresponding words or sentences Readability can also be improved.

3 is a view showing an example of the step of modifying the fixed width of Hangul to a variable width according to an embodiment of the present invention.

As shown in FIG. 3, before the kerning process, the user terminal 100 may modify the character width of the input character from a fixed width to a variable width, wherein the variable width to be modified is a variable width stored in advance. Based on the data 301, it may be a value set by matching the input character.

That is, according to the variable width data 301, when the variable width for the character "near" is set to "900", when the character "false" is input, the user terminal 100 is configured for the character "false" The character width can be modified from the fixed width "920" to the variable width "900".

On the other hand, according to the variable width data 301, the variable width for the letter "P" is set to "950". When the letter "P" is input, the user terminal 100 displays the letter "P". The character width can be modified from a fixed width of "920" to a variable width of "950".

In addition, as shown in FIG. 3, the variable width data 301 may have variable width set values matched to each of a plurality of characters, and the variable width set values may be set differently for each group.

For example, in the case of the letters "pa" and "뺘", the external shape is the same, that is, the font frame is the same and is grouped within the same group of letters, and the variable width is set to the same value of "950". On the other hand, in the case of the letters "Pa" and "Pak", the included groups are different, and the variable width may be set to different values ("Pa" is "950" and "Pak" is "940").

4 is a diagram showing an example of a step of grouping characters or characters based on a font frame according to an embodiment of the present invention.

As illustrated in FIG. 4, in generating kerning data, the user terminal 100 generates group data by grouping each of a plurality of Hangul characters or characters according to the shape of the characters or the characters, and stores the group data. have.

For example, the letters "almost", "west", "me", "seven", "shh", "lower", "ki", "poem" with the same shape as the second font frame 402 , "G" can be grouped into a second group, and the appearance of the letters is the same as the third font frame 403, the letters "O", "Yo", "Ru", "Yu", "U" You can group into 3 groups.

According to an embodiment of the present invention, not only Hangul characters but also special characters may be grouped according to the external shape, as shown in FIG. 4, left quotation marks "and" may be grouped into a ninth group.
