Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for outputting Hangul characters, and more particularly, to a novel method for assembling well-proportioned Hangul characters and outputting them for printing or display.

As is well known, the Hangul alphabet basically has 24 types of basic graphemes, and when composing a character, one character is assembled by composing 2 to 7 graphemes. Even if there is a character, if the arrangement of the graphemes differs depending on the character, the size will change.

By the way, as a conventional Hangul character printing device, there is one in which the above-mentioned graphemes, which are the basic elements of a character shape, are printed and the arrangement is manually performed. However, since this is a so-called type printing mechanism, when composing one character, the size of the graphemes cannot be changed as the graphemes are arranged. In addition, with this device, in order to synthesize a single Hangul character, the operator must perform shift operations such as upper and lower rows corresponding to the arrangement of graphemes, which is a complicated task. Furthermore, if characters of all sizes of glyphs are prepared, the printing mechanism becomes increasingly complicated, and the printing operation becomes even more complicated. Hangul Telex is a device that automatically performs such complicated printing operations.

Although the printing mechanism is a type, the only operation required to assemble a single character is to input glyme information, and after that, the electronic circuit automatically controls the number of characters without any operator instructions.
Characters are now printed. However, since this device is in the form of a type, it is not possible to vary the size of the grapheme depending on the character, and in reality, it is not possible to prepare typefaces with grapheme shapes of all sizes. However, it is still difficult to print a well-proportioned character shape. In addition, there are Hangul printing devices that have a printing mechanism that combines glyphs using dot display, and electronic display devices that use glyme synthesis that displays dots. It is prepared in a storage device and is capable of printing or displaying well-proportioned glyph shapes, but it has the disadvantage of requiring a large capacity glyph/graphic storage device. A method of displaying Hangul characters using an electronic display device has been considered in order to obtain even better character quality, but this method uses analog signals to control changes in the size and overlapping of character elements, and the control function is It has the disadvantage of little flexibility. In order to solve the above-mentioned problems of the prior art, the present invention stores the minimum number of Hangul basic glyphs in a storage device, and when combining the basic glyphs to synthesize one character. To print or display well-proportioned Hangul characters in a composite manner by varying the arrangement and the size of the graphemes associated with the arrangement according to a predetermined procedure. Below are the 24 basic graphemes (
According to the drawings, the content of the present invention is based on the assumption that 33 types of basic Hangul graphemes are used by adding 5 types of double consonant phonemes and 4 types of vertical complex phonemes to them. Explain in detail.

Figure 3 shows 33 types of basic Hangul glyph figures used in the present invention expressed as 5×5 pixel point information, and each pixel point corresponds to 1 bit information.

In the figure, 100 to 113 are single consonant grapheme figures of Hangul characters, 114 to 118 are double consonant grapheme figures that come to the first sound,
119 to 128 are monophthong grapheme figures, and 129 to 132 are vertical diphthong grapheme figures. In addition to these, there are compound consonants and mixed diphthongs as graphemes in Hangul, but these graphemes are composed of single consonant graphemes, single consonant graphemes, horizontal vowel graphemes and vertical single vowel graphemes, and can be formed by combining horizontal vowel graphemes and vertical diphthong graphemes. FIG. 2 shows a basic arrangement diagram when a single Hangul character is synthesized by arranging the basic Hangul glyph figures shown in FIG. 1 at appropriate positions within a predetermined character frame according to the present invention. be.

Here, 200 indicates the basic size of the Hangul basic character element figure, for example, the size of 5×5 pixel points shown in FIG. 201 shows the size of a character frame forming one Hangul character and the basic arrangement of Hangul basic glyphs arranged within the character frame.

Further, numerals such as 1H, 2H, 1V, and 3 mean magnifications, H means multiplying the horizontal direction, and V means multiplying the vertical direction. In other words, when synthesizing a single Hangul character, the present invention enlarges the basic glyph figure shown in FIG. hand,
By arranging it at the appropriate position within the character frame of 201,
It assembles well-proportioned Hangul characters. 2
From the relationship between 00 and 201, the Hangul basic glyph figure is 5×
When expressed as 5 pixel points, one Hangul character that can be assembled is 1
It is represented by 0x15 pixel points.

Here, Hangul characters are classified into nine types, 301 to 309 in Figure 3, depending on the arrangement of their glyph groups.

In Figure 3, the first single consonant or the first double consonant is C.
When expressed as Va for vertical monophthongs or vertical diphthongs, Vb for horizontal vowels, C for final single consonants, and C+C for final double consonants or compound consonants as two single consonants, each is 301. is C+Va, 302 is C+Va+C, 303 is C+a+C+C, 304 is C+Vbl3O5 is C+Vb
+Cl3O6 is C+Vb+C+Cl3O7 is C+Vb+
Va, 308 is C+Vb+Va+C, 309 is C+Vb
It takes the combination of +Va+C+C. 1H, 2
H, 1V, 1, 5V, 2V, and 3 are the magnifications of the grapheme figures arranged at the corresponding positions.

That is, the combination of C, a, and Vb uniquely determines the dislocation and size of the graphemes that make up one Hangul character. Hereinafter, information indicating the arrangement of character elements uniquely determined from C, Va, and Vb will be referred to as arrangement information, and information such as 1H/1V, 1H/1.5V, etc. indicating the size of the character element will be referred to as magnification information. I will call it . FIG. 4 shows the principle of synthesizing a single Hangul character according to the present invention. In other words, when composing the Hangul character "made",
From the group of Hangul basic glyphs in Figure 1 []” (100)
, (ding) (125), "-11" (131) [pi] (1
Select 03). On the other hand, the Hangul character "ν" belongs to classification 308 in FIG. Therefore, the magnification information 1H/1V, 1H/1V, 1H/2V, 2H/1V shown at 308 in FIG.
According to the pattern 400, 401, 402, 4 of FIG.
Expand these patterns to 30
One character is assembled by arranging it as shown in 404 in FIG. 4 according to the arrangement information prepared in advance showing the arrangement relationship of the numbers 8 and 8. FIG. 5 is a block diagram of one embodiment of the present invention. In the figure,
Reference numeral 500 denotes an input device such as a keyboard on which a number of character input keys corresponding to the prime numbers of Hangul basic characters shown in FIG. This outputs the corresponding grapheme code. In this example, the grapheme code is B.
It is assumed that the code shown in FIG. 6 is assigned to each of the 33 types of Hangul basic glyphs, which are composed of 8 bits from .about.B7. In Figure 6, the 5 bits of BO-B4 indicate the code pattern of 33 basic Hangul graphemes, and the 3 bits of B5 to B7 indicate whether the corresponding grapheme is a vowel or a consonant.
This bit indicates whether it is a diphthong or a single consonant, a horizontal monophthong, a vertical monophthong, or a diphthong. Specifically, B
If 7 is "1", it means a vowel, "0" means a consonant, and when B7=0, B6 means "1" means a double consonant, "
O゛ means a single consonant, when B7 = 1, ``1'' means a horizontal single vowel, 60゛ means a vertical single vowel,
When B7-1 and B6=0, "1" means a diphthong. Each glyme code for one Hangul character sent from the input device 500 is stored in the buffer storage section 501.

The layout information search unit 502 has a layout information conversion table corresponding to 301 to 309 in FIG. The arrangement of the key-input Hangul basic glyphs, that is, the combination of C, Va, and Vb, is determined to which one in Figure 3 corresponds, and the corresponding arrangement information is converted into the above conversion table. Search and output. The magnification information search unit 503 is configured from 301 to 301 in FIG.
It has a magnification information table corresponding to 309, and similarly to the block 502, bits B5 to B7 of each glyph code for one Hangul character stored in the buffer storage unit 501 are checked, and its C, Va, and Vb are Search and output magnification information corresponding to the combination. On the other hand, the grapheme pattern storage unit 5
04 stores pattern information of 33 types of Hangul basic glyphs shown in FIG.
Bit B of each glyme code for one Hangul character stored in 1.

-B4 is used as a read address, and pattern information of a group of basic glyphs that make up one Hangul character is sequentially output. In the pattern enlargement processing section 505, the magnification information search section 50
Using as input the magnification information obtained in step 3 and the pattern information of the basic glyph figures read from the glyph pattern storage unit 504, pattern synthesis processing is performed by sequentially enlarging each basic glyph figure that composes one Hangul character. 506. In the pattern synthesis processing section 506, the pattern enlargement processing section 50
Each piece of pattern information enlarged to a predetermined magnification given by No. 5 is placed at a predetermined position within the character frame based on the arrangement information obtained by the arrangement information search section to synthesize one Hangul character. Graphic information (pattern information) of one Hangul character synthesized by the pattern synthesis processing section 506 is outputted through a signal line 507. The output device connected to the signal line 507 may be either a printing device or an electronic display device. Next, the operation of each unit in FIG. 5 will be explained in more detail, taking as an example the case of synthesizing the Hangul character "Yal".

It is now assumed that the Hangul basic glyphs in the dot representation format shown in FIG. 1 are stored in the glyph pattern storage unit 504 in the stroke representation format.

FIG. 7 is a diagram for explaining this. That is, when the dot pattern information shown in FIGS. 7-a and 7-b is expressed in stroke form, it becomes as shown in FIGS. 7-c and d. In figures c and d, dashed lines mean pen-off and solid lines mean pen-on. In this embodiment, the coordinate points of these strokes are B. - Represented by 8 bits of B7. Figure 7e shows the code format, where BO-B3 is the y coordinate, B4 to B6
represents the x coordinate, respectively. The most significant bit, B7, is assigned to a pen-on/pen-off identification bit; ``pi'' indicates pen-on, and ``0'' indicates pen-off.
FIG. 7f shows a part of the basic glyph figure memory map stored in the glyph pattern storage unit 504, and addresses A and A+1 are stroke representation patterns corresponding to the basic glyph figures in FIG. 7a. Data, similarly, addresses B, B+
1, B+2, B+3, and B+4 are pattern data of stroke expressions corresponding to the basic glyph figures shown in FIG. 7b. Note that the movement of the pen is always at the coordinates (0,0) for each pattern.
The coordinates are not particularly stored in the memory. This saves pattern memory capacity. In Fig. 7f, the all-1 data stored at addresses A+2, B+5, etc. indicates the end of the pattern data for one character element.Now, when composing the Hangul character "豐" , "]", "T", "ten" on the input device 500 according to the grammar of Hangul character composition.
, ``已'' in sequence, and then press the space key to indicate a character break.

FIG. 8 shows the grapheme codes stored in the buffer storage unit 501 in this case. In the diagram, “00
001000'' means a space code, and the others correspond to the code conversion table in FIG. The contents of upper bits B7 to B5 of the grapheme code group stored in the buffer storage section 501, excluding the space code, are given to the arrangement information search section 502 and the magnification information search section 503. The arrangement information search unit 502 searches bit B of each glyme code for one Hangul character given from the buffer storage unit 501.
The combinations 5 to B7 are investigated, and the corresponding arrangement information is searched using a arrangement information conversion table prepared in advance.

Of the four graphemes that make up the Hangul character "ya", "]" is the first consonant of C, and "T" is the horizontal vowel of Vb.
, "ten" is a vertical diphthong vowel Va, "已" is a final single consonant sound C, and the basic Hangul glyphs entered by key are C+b+V.
It can be seen that it is a combination of a+C. This corresponds to 308 in Figure 3, and in this case, the location information is the coordinate (0
, 0), (0, 4), (4, 0), and (0, 8) are retrieved. In Cs, (0,0) is the starting position of the grapheme "ko" (point 22 in Figure 3), and (Y, 4) is "T".
” start position (point 23 in Figure 3), (4,0) is “
The starting position of ``Yam'' (point 24 in Figure 3) and (0,8) respectively indicate the starting position of ``Pi'' (point 25 in Figure 3). The arrangement information searched by the arrangement information search section 502 is given to the pattern synthesis processing section 506. Similarly, the magnification information retrieval unit 503 also searches for bit B5 of the grapheme code group for one Hangul character given from the buffer storage unit 501.
~From B7, the basic Hangul glyphs input by key are C+Vb
It decodes that it is a combination of +Va+C, and searches for magnification information of the magnification shown at 308 in FIG. 3 from a magnification information table prepared in advance. In other words, the magnification of the grapheme "-1" (1H
, 1V), the magnification of [T] (1H, 1V), the magnification of [1H, 2V), and the magnification of "self" (2H, 1V) are searched. On the other hand, the pattern storage unit 504
Now, bit B of each grapheme code given from the buffer storage unit 501. -Access the pattern memory based on B4 and read out the stroke data of the basic graphemes ``ko'', ``T'', ``-1'', and ``已'' one after another.
For example, if the code ``00001010'' indicating the grapheme ``-1'' is given, the A address of the pattern memory is first specified, its contents are read, and then the address is incremented by 1. The contents of the (A+1) address are read.

Then, the address is incremented by 1 again, and the contents of (A+2) are
In other words, when the data indicating the end of the pattern data of one glyph element is read out, the reading of one pixel element is finished. below,"
The same applies to ``di'', ``-11'', and ``pi''. The graphemes "ko", "cho", "
Magnification information of “Hl” and “W” and pattern storage unit 50
The stroke data of the grapheme group read from 4 are input to the pattern enlargement processing unit 505. The pattern enlargement processing unit 505 calculates x and y of the corresponding basic glyph based on the magnification information obtained by the magnification information search unit 503.
Expansion processing of the directional stroke length is executed.

For example, if the basic glyme figure "]" is enlarged by 1 times in the x direction and 1.5 times in the y direction, the stroke data of the glyme "]" before enlargement shown in Figure 9a is As a result of the processing, the result becomes as shown in figure b. Note that during the enlargement process, the bits in the stroke data indicating whether the pen is on or off are stored in a separate register, and the decimal parts obtained when the data is enlarged are discarded. FIG. 10 shows the previous magnification information (1H, 1V) obtained by the magnification information search unit 503,
(1H, 1V), (1H, 2V), (2H, 1V) to make it easier to understand the characters "]], "T", and "-111. This is shown in stroke representation. The pattern information of each glyph that has been enlarged by the pattern enlargement processing unit 505 is sent to the pattern synthesis processing unit 5.
06 is input, and the Hangul character "Se1" is synthesized by arranging it at a predetermined position in the character frame based on the arrangement information previously given by the arrangement information search unit 501. FIG. 11 shows the movement of the pen at that time, and the broken line indicates pen-off. In the above example, the Hangul character "!" is synthesized in the stroke format, but of course the present invention is not limited to this, and as shown in FIG. 4, it can also be synthesized in the dot format. Needless to say, it is included.

Further, in the embodiment, the number of Hangul character input keys corresponding to the 33 basic character prime numbers shown in FIG. 1 is prepared, but the number of input keys prepared may be 33 or less.

In other words, a double consonant in the first voice can be obtained by pressing the corresponding single consonant key twice, and a vertical diphthong in the middle voice can be obtained by pressing the vowels to be compounded twice in sequence. Therefore, a minimum of 24 grapheme keys is sufficient. Furthermore, the basic layout diagram 201 in FIG. Figure 20
Apply the principle diagram in Figure 3 by multiplying the basic size of the 0 character figure by a real number (including reduction), or change the basic layout diagram of 201 in Figure 2 horizontally or vertically, or It does not depart from the idea of the present invention to apply the method shown in FIG. 3 by multiplying the horizontal and vertical directions by real numbers, and further by multiplying the basic size of the 200 character figures by real numbers.

As is clear from the above explanation, according to the present invention, it is sufficient to prepare one glyme pattern for each of about 30 basic glymes in the pattern storage device, so the capacity of the pattern storage device is small. Moreover, in order to assemble one Hangul character by multiplying the glyph pattern read from the pattern storage device by N times horizontally, vertically, or both vertically and horizontally as necessary,
It becomes possible to print or display all the currently used Hangul characters by combining them into a well-proportioned character shape.
