Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a Hangul character image pattern generation processing method, in particular a method for generating each Hangul glyph image pattern corresponding to a plurality of Hangul glyph codes belonging to one Hangul character. Submitted in parallel from the character generator,
The present invention relates to a Hangul character image pattern generation processing method that electrically synthesizes these to generate an image pattern of one Hangul character.

As is well known, Hangul characters are composed of a combination of Hangul glyphs that correspond to consonants, Hangul glymes that are vowels called horizontal vowels, and Hangul glyphs that are vowels called vertical vowels.

Figure 1 A, B, and C show examples of Hangul characters. Figure 1 A is a combination of consonant C and vertical vowel Vv, and Figure 1 B is a combination of consonant C, horizontal vowel V, and consonant. C is a rough combination of the consonant C, the vertical vowel Vv, and the consonant C.

As can be seen from Figure 1 A, B, and C, even consonants with the same form differ in size depending on the manner in which they are combined with others.
They have different image patterns. When outputting such image patterns of Hangul characters, the number of combinations of each Hangul glyph is enormous, and it is not a good idea to store each Hangul character in a character generator. An image pattern corresponding to a Hangul glyph is prepared in a character generator and read out.

However, as described above, since the sizes and the like differ depending on the combination mode, a plurality of image patterns of different sizes are prepared corresponding to each Hangul glyph. FIG. 2A, B, C, D, E, and F represent the manner in which Hangul glymes are combined in Hangul characters.

That is, FIG. 2A shows the combination C of consonant C and vertical vowel Vv.
Vv, Figure 2B is the combination CVvC of consonant C, vertical vowel Vv and consonant C, Figure 2C is the combination CVHVv of the consonant, horizontal vowel VH and vertical vowel Vv, Figure 2D is the combination of consonant C and The combination CVH with horizontal vowel VH, Figure 2 E is the combination CVHC with consonant C, horizontal vowel VH and consonant, and Figure 2 F is the combination of consonant C, horizontal vowel VH, vertical vowel Vv and consonant C. It represents CVHVvC. As can be seen from Figure 2, there are four sizes of Hangul glymes, which correspond to the consonants that make up one Hangul character: C, , C2, C3, and C4, and the horizontal vowel VH also has four sizes: VH, , VH2, VH
3. Four types of VH4 may be considered, and four types of vertical vowels Vv may be considered: Vv·, Vv2, Vv3, and Vv4.

Figure 3 A, B, C, D are shown in Figure 2 C, , C2, C3,
An example of an image pattern corresponding to C4 is shown.

As mentioned above, in the case where the consonant C, the horizontal vowel VH, and the vertical vowel Vv have a plurality of different image patterns, the desired Hangul glyme codes belonging to one Hangul character can be extracted. Hangul jjime image
The purpose of this invention is to selectively output patterns and synthesize them to obtain the desired image pattern of one Hangul character.

For that purpose, the Hangul character image of the present invention
The pattern generation processing method stores multiple types of image patterns for the same Hangul glyme code in a character output processing system that inputs multiple Hangul glymes and prints or displays the Hangul characters. The character generator is divided into at least consonants, horizontal vowels, and vertical vowels, and is provided so as to be accessible independently of each other, and is provided corresponding to each character generator and inputted. A data buffer in which consonant, horizontal vowel, and vertical vowel grapheme codes are stored independently, and a Hangul character to be output based on a plurality of Hangul glyme codes belonging to one Hangul character to be output stored in the data buffer. a forming checker for determining the form of the character generator; and an address/forming checker provided corresponding to each of the character generators and storing the glyph codes from each of the data buffers and the forming information from the forming checker. register, accesses each of the character generators in parallel based on the contents of the address register, and generates Hangul character image patterns corresponding to the plurality of Hangul character element codes in parallel. The present invention is characterized in that each Hangul character image pattern generated from the divided character generator is synthesized in a bit-corresponding manner to generate one desired Hangul character image pattern.

This will be explained below with reference to the drawings. FIG. 4 is an embodiment showing the main part of accessing the character generator based on Hangul glyph codes input in sequence, and FIG. 5A
, B, C, and D are images of Hangul characters constructed by combining each image pattern derived from each segmented character generator and the image pattern.

In FIG. 4, 1-1, 1-2, 1-3, and 1-4 are data buffers that constitute display buffers, and 2 is a control buffer that selects the image pattern of Hangul glyphs in the character generator. In order to select the form of the Hangul character (the form shown in FIG. 2) based on whether there is no data buffer 1-1 or the contents set in 1-4, the corresponding forming information is input. 3 is a forming checker, CPA2 and CPAI are address bits corresponding to forming information, and select different image patterns under the same Hangul character code;
4-1 None, 4-4 are character generator access address registers, 5-1 to 5-4, respectively.

As can be seen from the form of Hangul characters shown in Figure 2, the input order of the Hangul glyphs constituting one Hangul character is determined, and first, C, , C, which correspond to at least consonants.
2, C3 is input, then if there is a horizontal vowel, the horizontal vowel is input, then if there is a vertical vowel, the vertical vowel is input, then if there is consonant C4, it is input. is input. Focusing on this point, in the case shown in FIG. If any of the horizontal vowels VH, , VH2, VH3, or VH4 exists, the code for the horizontal vowels VH, , VH2, VH3, or VH4 is set in the data buffer 1-2, and is emptied if the code does not exist.
, Vv2, Vv3, Vv4, if any of them exists, the code is set, and if none exists, it is emptied, and the data buffer 1-4 further contains the Hangul glyme code corresponding to the consonant (the code corresponding to C4). ) is set if it exists, and is emptied if it does not exist.

Note that this control may be considered to be performed by a microprocessor (not shown). In the case shown in FIG. 4, codes are set in data buffers 1--, 1-3, and 1-4.

These sets of codes are supplied to the forming checker 3 in order, and the forming checker 3 checks which form the Hangul character to be output has as shown in FIG. Put the information into control buffer 2 and set the output of this control buffer to address bit CPA2.
