The present invention relates to a Hangul character input display processing method, and more particularly to a control method of keyboard input and display display in the Hangul character input display device. Background Art [0002] Conventionally, a device for inputting a plurality of Hangul alphabets (字母: consonants and vowels) and assembling them into Hangul characters is known, for example, from Japanese Patent Laid-Open No. 57-158687. This is what the operator enters while looking and seeing what the alphabet is not as it is now.

In other words, a determination circuit for determining the alphabets to be input in order, at least one buffer memory for storing the alphabets or patterns of the alphabets before the inputted combinational characters, and the point in time at which the alphabets input in sequence can be combined A combination character memory for storing as a combination character in the combination character, a combination character display portion for displaying the contents of the combination character memory in a pattern, and at least one letter mark for displaying the contents of the buffer memory as a pattern, which is provided corresponding to the buffer memory. It had a letter display part, displayed a combination letter, and also displayed a letter that could not be entered.

In Japanese Patent Application Laid-Open No. 56-65282, a consonant code storage unit for storing inputted phoneme codes sequentially and a Hangul phoneme given by each phoneme code based on the Hangul phoneme code stored in the phoneme code storage unit A phoneme judging unit for judging whether or not it is a collection, a display buffer in which the phoneme codes set in the phoneme code storage unit are set in pairs with the sequential control information, and the cursor position on the display screen is controlled based on the judgment result of the phoneme judging unit. A cursor control unit and a display buffer control unit for controlling the storage contents of the display buffer are provided at least, and in accordance with the determination result of the phoneme determination unit in accordance with the sequence of Hangul characters that are sequentially inputted, the cursor is determined by temporarily determining one Hangul character assembly. Move and revise one previously determined Hangul character based on the next Hangul alphabet. The display based on the contents of the display buffer was sequentially displayed on the display screen.

In any of the above cases, the Hangul alphabet (or phoneme) during the combination of Hangul combination characters was displayed on the screen. However, the related art has drawbacks in that it requires more display area than necessary and it is difficult to correct characters in sentences.

The present invention is to provide a Hangul character input display processing method of a simple configuration that solves the problems of the prior art.

The present invention provides an input / output control unit for determining whether input codes sequentially input are character codes or cursor information codes in a Hangul character input display processing method for inputting a plurality of Hangul characters and assembling them into Hangul characters. The memory read write control unit for writing and reading the character code outputted from the control unit into the memory, the memory in which the character code is temporarily stored by the memory read write control unit, and the character code read by the memory lead write control unit Hangul alphabet / alphanumeric symbol judging section for judging whether it is a Jamo code or an alphanumeric code, and from the judging section, the Hangul Jamo is assembled and assembled based on the Hangul Jamo code. Hangul character assembly control unit for converting to Hangul character code, and Hangul from the assembly control unit A refresh buffer control unit for outputting a character code or an alphanumeric symbol code from the determination unit, a CRT controller control unit for outputting a cursor control signal based on a cursor information code and a display state from the input / output control unit, and from the refresh control unit Outputs a video signal based on a refresh buffer for giving address information based on an output code, a font memory for outputting font pattern data corresponding to an output signal of the refresh buffer, the font memory, and an output signal from the CRT controller control unit. And a CRT display unit for displaying characters and cursors at desired positions on the display screen based on the output signal of the CRT controller.

According to the present invention, the Hangul character input display processing method is constructed as described above. When the Hangul character is displayed, the Hangul character code is stored in the memory until the assembly of Hangul characters is confirmed by the Hangul character assembly control unit, and the assembled Hangul character code is confirmed. Display the Hangul characters, and the display controller controls the position on the display screen corresponding to the one-character length of the alphanumeric symbol, which is equivalent to two characters of the half-width cursor and the alphanumeric symbol. This problem can be solved by outputting a cursor control signal indicating a full-width cursor for determining a position on the display screen corresponding to the above, and using the half-width and full-width cursors to correct the characters on the display screen. .

Embodiments according to the present invention will be described with reference to the accompanying drawings.

2 is a block diagram showing an embodiment according to the present invention, where 1 is a keyboard, 2 is a central processing unit, 3 is a memory, 4 is a refresh buffer, 5 is a font memory, 6 is a CRT controller, and 7 is a CRT display.

Figure 1 is a block diagram showing an embodiment in detail corresponding to the function of the central processing unit according to the present invention of Figure 2, 2a is a keyboard input and output control unit, 2b is a memory lead write control unit, 2c is a Korean alphabet / alphanumeric sign plate 2d is a Korean character assembly control unit, 2e is a refresh buffer control unit, and 2f is a CRT controller control unit.

Next, the operation will be described.

The 8-bit code input from the keyboard 1 determines whether it is a character code or a cursor information code by the keyboard input / output control unit 2a. If the input code is a character code, it is output to the memory read / write control unit 2b, and the cursor information code. If so, it is output to the CRT controller control unit 2f.

If the character code is input now, the memory read / write control unit 2b sequentially stores the input character code in the memory 3.

The read / write character code stored in the memory 3 is read by the memory read / write control unit 2b, and the Hangul alphabet / alphanumeric symbol determination unit 2c determines whether the read character code is a Hangul alphabet code or an alphanumeric code. If it is a code, the Hangul Jamo code is stored in the memory 3 in sequence, and the Hangul character assembly control unit 2d again determines the combination check and truncation of the characters from the Hangul Jamo input string. A 16-bit code for displaying Korean characters is converted and output to the refresh buffer control unit 2e.

On the other hand, if the read character code is an alphanumeric symbol code, the Hangul alphabet / alphanumeric symbol determination unit 2c outputs the 8-bit code as it is to the refresh buffer control unit 2e.

The refresh buffer control unit 2e stores the input Korean 16-bit code or the alphanumeric 8-bit code in the refresh buffer 4. The refresh buffer 4 gives address information to the font memory 5 by the stored code, and the font memory 5 outputs font pattern data corresponding to the address information to the CRT controller 6.

The CRT controller 6 converts the input font pattern data into a video signal and outputs it to the CRT display unit 7. In accordance with the input video signal, the CRT display unit 7 displays the character at a predetermined position on the screen. Next, when a cursor information code indicating cursor information is input to the keyboard input / output control unit 2a, the keyboard input / output control unit 2a outputs the cursor information code to the CRT controller control unit 2f.

The CRT controller control section 2f outputs a cursor control signal to the CRT controller 6 which designates a position or the like on the screen of the input character in accordance with the input cursor information code. The CRT controller 6 converts the input cursor control signal into a video signal and outputs it to the CRT display unit 7.

The CRT display unit 7 displays the full-width or half-width cursor display corresponding to the Hangul characters or alphanumeric symbols in accordance with the input video signal at a designated screen position. 3 is a diagram showing an example of display when inputting and correcting Hangul characters. FIG. 3 (a) shows an example of inputting Korean characters and alphanumeric symbols. When inputting in the order of ㅎ, ㅎ, ㅏ, ,, ,, ,, ,, ,, ,, ,, ,, and C on the keyboard 1, first, the half-width cursor is moved to the desired position by using the cursor movement keys. Since the combination of characters is not known until the point in time at which "h, n, b, a" is inputted, the display contents remain the cursor display.

Next, the vowel "U" is input and the combination of characters is determined. Therefore, the character "HAN" is displayed and the half-width cursor is moved to the next input area.

When inputted again as "d, A", the next combination of characters is confirmed and the display is "Han, A, A." "B, C" is an alphanumeric code, so display it as it is input. FIG. 3 (b) shows an example of correcting an alphanumeric symbol with Korean characters.

First, move the half-width cursor to the character "A" to correct using the cursor movement key "←".

Next, input Korean letter “ㅁ, ㅜ, ㄴ” in order, and move the half-width cursor to the right by using the cursor mover “→” to display the assembled Korean character “moon” and half-width “B, C”. Move to the minute rightward and display the half-width cursor at the position "B".

(The movement of the half-width right direction of "B, C" is controlled by the CRT controller control section 2f.) Next, the half-width cursor is moved to the next input area by using the cursor shift key "→". 3 shows an example of correcting a Hangul character with an alphanumeric symbol.

First, move the half-width cursor to the character "door" to correct using the cursor movement key "←", and the half-width cursor becomes the full-width cursor.

The next time you enter "A" for the alphanumeric symbol, the display changes from "Hangul" to "A" and moves "B, C" to the left half-width to make the full-width cursor become a half-width cursor. Is displayed.

In the case of the full-width cursor, since the half-width two-character amount is moved by one cursor operation, it is controlled by the CRT controller control unit 2f.

4 is a flowchart for implementing the present invention. Step 1 is a process for moving the cursor to the input position. Step 2 is a process of inputting characters from the keyboard. As shown in FIG. 3, that is, the characters are input in the order of "h, u, b, a, a,-, d, A, B, C". Step 3 is a process of determining whether the input character is a Hangul alphabet.

In the example shown in Fig. 3 (a), since the first character inputted is "ㅎ" of the Hangul alphabet, the determination result is "Yes", and the process moves to Step 4.

On the other hand, when "A" other than the Hangul alphabet is input as described later, the result of the determination is "No", and the process moves to Step 11.

Step 4 is processing when the input character is a Hangul alphabet, and is a process of storing the Hangul alphabet code in the memory 3 (see FIG. 2). Step 5 is a process of determining whether the input character is a Korean vowel.

In the example shown in Fig. 3 (a), since the first character entered is "ㅎ" other than the Korean vowel, the determination result is "No" and the process returns to step 2.

On the other hand, when the Hangul vowel "-" is input as described later, the result of the determination is "Yes", and the process shifts to Step 6. Step 6 is a process for determining whether Korean characters have been combined in the Korean alphabet input so far.

In the example shown in FIG. 3 (a), when the Hangul vowel “U” is input, the Hangul alphabets input so far are “ㅎ, ㅏ, ㄴ, ㄱ” and the Hangul characters “Han” are assembled by these Hangul alphabets. The determination result is "Yes", and the process shifts to step 7.

On the other hand, when the Hangul characters are not assembled, the determination result is "No" and the process returns to Step 2. Step 7 is a process of converting a Korean character into a code for displaying.

When "han" is assembled as a Korean character, the conversion is made to the corresponding code. Step 8 is a process of storing the code converted in step 7 in the refresh buffer 4 (see FIG. 2) and displaying Korean characters on the CRT display unit 7 (see FIG. 2). When the conversion to the code corresponding to the Hangul character "Han" is made in Step 7, the code is stored in the refresh buffer 4.

In the refresh buffer 4, codes of characters displayed on the CRT display unit 7 (see FIG. 2) are stored at addresses corresponding to the display positions, and these codes are sequentially stored in the font memory 5 (see FIG. 2). Will be displayed. The font memory 5 outputs display data corresponding to the code as an address of the input code. The display data is output to the CRT controller 6 (see also FIG. 2), and again to the CRT display unit 7 to display characters.

Step 9 is a process of moving the cursor to input the next character.

Step 10 is a process for determining whether or not to finish inputting a character. When it is finished, the result of the determination is "Yes", and the input process ends. On the other hand, when it is not finished, the judgment result is "No" and the process returns to Step 2. Step 11 is a process for determining whether the Hangul alphabet has been assembled by the Hangul alphabet input so far as in Step 6. In the example shown in FIG. 3 (a), it is executed when "A" is input.

At this time, the Korean alphabet input so far is "ㄱ, ㅡ, ㄹ" (where "ㅎ, ㅏ, ㄴ" is already assembled into the Korean character "Han" and is not subject to determination). do. Therefore, the determination result becomes "Yes", and the process shifts to step 12.

On the other hand, if "B" in the example shown in FIG. 3 (a) is input, it is not the Korean alphabet input so far (however, as described above, "ㅎ, ㅏ, b, ㄱ, ㅡ, ㄹ" It is not a judgment object because it is composed of the Korean characters "Han" and "Written". Step 12, step 13, and step 15 are the same processes as step 7, step 8, and step 9 described above, and thus description thereof is omitted. Step 14 is a process of storing codes of characters other than Korean characters (receipt symbols) in the refresh buffer 4 to display the alphanumeric symbols on the CRT display unit 7. In the example shown in FIG. 3 (a), it is a process of displaying "A, B, C".

The input processing of the characters shown in FIG. 3 (a) has been described above.

In the process of correcting the characters in FIGS. 3B and 3C, the process of inputting a character after moving the cursor to a position to be corrected is the same as the flow chart described above.

As described above, in order to display Korean characters in full size and alphanumeric characters in half size, it is possible to take a large number of displayed characters, and furthermore, to determine the truncation of characters from the Jamo input string of Korean characters, In order to display at the viewpoint, there is no need for an extra display area, and there is an effect that the input characters can be corrected by simple cursor control. Also, by using this function, it can be applied to Korean word processor or personal computer.
