DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a Hangul character input/display processing method, and more particularly to a control method for keyboard input and display display in a Hangul character input/display device.

(Prior Art) Conventionally, a device that inputs a plurality of Hangul characters to assemble and display Hangul characters has been developed, for example, by
No. 57-158687 discloses a determination circuit that determines the sequentially input characters, at least one buffer memory that stores patterns of previous characters that are input to form a combination character, and a combination of characters that are input sequentially. a combination character memory that stores the combination characters as a combination character when the combination character is used; a combination character display section that displays the contents of the combination character memory as a pattern; and at least one combination character display section that is provided corresponding to the buffer memory and displays the contents of the buffer memory as a pattern. It was equipped with a character display section capable of displaying characters, and displayed combination characters as well as character characters that could not be combined that had just been input.

Furthermore, in Japanese Patent Application Laid-open No. 56-65282, there is a gramme code storage section that sequentially stores the input grameme codes, and a gramme code is stored in each grameme code based on the Hangul grameme code stored in the grameme code storage section. A grapheme determination unit that determines whether a given Hangul grapheme is a consonant or a vowel; a display buffer in which the grapheme codes set in the grapheme code storage unit are sequentially set by being matched with control information; The device includes at least a cursor control unit that controls the cursor position on the display screen based on the determination result of the glyme determination unit, and a display buffer control unit that controls the contents stored in the display buffer, and the Hangul glyme that is sequentially input. In accordance with the determination result by the glyme determination unit, one Hangul character set is tentatively determined and the cursor is moved, and the first Hangul character set is tentatively determined based on the next input Hangul glyme. The system is configured to display modified Hangul characters, and displays based on the contents of the display buffer are sequentially displayed on the display screen.

In any of the above cases, the Hangul alphabet (or glyme) in the middle of the combination of Hangul combination characters is displayed on the screen.

(Problems to be Solved by the Invention) However, the prior art has disadvantages in that it requires a larger display area than necessary and that it is difficult to correct characters in sentences.

The present invention provides a simple Hangul character input and display processing method that solves the problems of the prior art.

(Means for Solving the Problems) The present invention provides a Hangul character input/display processing method for assembling and displaying Hangul characters by inputting a plurality of Hangul characters. an input/output control section that determines whether the a Hangul alphabet/alphanumeric symbol determination unit that determines whether the character code read by the memory read/write control unit is a Hangul alphabet code or an alphanumeric symbol code, and a Hangul alphabet code from the determination unit. a Hangul character assembly control unit that controls the assembly and assembly of Hangul characters based on the assembly, and converts the assembled Hangul characters into a Hangul character code corresponding to the assembled Hangul characters after the assembly is completed; and a Hangul character code from the assembly control unit or the above-mentioned determination. a refresh buffer control unit that outputs an alphanumeric symbol code from the unit;
a display controller control section that outputs a cursor control signal based on the cursor information code and display state from the input/output control section; and a refresh buffer that provides address information based on the output code from the refresh buffer control section. a font memory that outputs font pattern data corresponding to the output signal of the refresh buffer; a display controller that outputs a video signal based on the font memory and the output signal from the display controller control section; The display unit includes a display unit that displays characters and a cursor at desired positions on the display screen based on output signals from the controller.

(Function) According to the present invention, since the Hangul character input and display processing method is configured as described above, when displaying Hangul characters, the Hangul characters are stored in the memory until the Hangul character assembly is finalized by the Hangul character assembly control section. After determining the Hangul character code, the assembled Hangul character code is output to display the Hangul character, and the display controller control unit also outputs a half-width cursor and an alphanumeric character that determines the position on the display screen corresponding to one alphanumeric character. When correcting characters on the display screen by outputting a cursor control signal representing a full-width cursor that determines the position on the display screen corresponding to one Hangul character corresponding to two characters of the symbol, the half-width and Since the correction is made using a full-width cursor, the above-mentioned problem can be solved.

(Example) An example according to the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a block diagram showing an embodiment of the present invention, in which 1 is a keyboard, 2 is a central processing unit (CPU), 3 is a memory, 4 is a refresh buffer, 5 is a font memory, 6 is a CRT controller, and 7 is a block diagram showing an embodiment of the present invention. is the CRT display section. FIG. 1 is a block diagram showing an embodiment in more detail corresponding to the functions of the CPU according to the present invention shown in FIG. 2d is a Hangul character assembly control section, 2e is a refresh buffer control section, and 2f is a CRT controller control section.

Next, we will define the operation. The 8-bit code input from keyboard 1 is sent to keyboard input/output control section 2.
At step a, it is determined whether the input code is a character code or a cursor information code, and if the input code is a character code, it is output to the memory read/write control unit 2b, and if it is a cursor information code, it is output to the CRT controller control 2f. If character codes are now input, the memory read/write control section 2b sequentially stores the input character codes in the memory 3. The memory read/write controller 2b reads the character code stored in the memory 3, and the Hangul alphabet/alphanumeric symbol determination unit 2c determines whether the read character code is a Hangul alphabet code or an alphanumeric symbol code. If so, the Hangul alphabet codes are sequentially stored in the memory 3, and the Hangul character assembly control unit 2d also performs a combination check and character separation judgment from the Hangul alphabet input string, and when one Hangul character is assembled, the Hangul characters are show
It is converted into a 16-bit code and output to the refresh buffer control section 2e. On the other hand, if the read character code is an alphanumeric symbol code, the Hangul alphabet/numerical symbol determination section 2c outputs it as an 8-bit code to the refresh buffer control section 2e. The refresh buffer control unit 2e inputs Hangul 16
A bit code or 8 bits of alphanumeric characters is stored in the refresh buffer 4. The refresh buffer 4 gives address information to the font memory 5 based on the stored code, and the font memory 5 stores font pattern data corresponding to the address information.
Output to CRT controller 6. The CRT controller 6 converts the input font pattern data into a video signal and outputs it to the CRT display section 7.
The CRT display unit 7 displays characters at predetermined positions on the screen according to the input video signal.

Next, when a cursor information code indicating cursor information is input to the keyboard input/output control unit 2a,
The keyboard input/output control section 2a outputs the cursor information code to the CRT controller control section 2f. The CRT controller control unit 2f generates a cursor control signal that specifies the position of the input character on the screen, etc. based on the input cursor information code.
Output to CRT controller 6. The CRT controller 6 converts the input cursor control signal into a video signal and outputs it to the CRT display section 7. The CRT display unit 7 displays a full-width or half-width cursor corresponding to Hangul characters or alphanumeric symbols at a designated position on the screen according to the input video signal.

FIG. 3 is a diagram showing an example of display when inputting and correcting Hangul characters.

FIG. 3a shows an example of inputting Hangul characters and alphanumeric symbols. From keyboard 1 “〓、
When inputting in the order of "〓,〓,,∠,〓,A,B,C", first move the half-width cursor to the desired position using the cursor movement key. The displayed content remains as a cursor until ``〓、〓、,'' is input because the combination of characters is not known. Next, the vowel "-" is input, the character combination is determined, the character "〓" is displayed, and the half-width cursor is moved to the next input area. Furthermore, “〓,A”
When inputted, the next character combination is determined and the display becomes ``〓,〓,A''. Since "B, C" are alphanumeric symbol codes, they are displayed each time they are input.

FIG. 3b shows an example of correcting alphanumeric symbols to Hangul characters. First, use the cursor movement key "←" to move the half-width cursor to the character "A" to be corrected. Next, the Hangul alphabet “□、
⊥,'' in order, then press the cursor movement key ``→''
If you move the half-width cursor to the right using
The assembled Hangul character “〓” is displayed, and “B,
Move "C" to the right by a half-width amount and display the half-width cursor at the position of "B". (The half-width movement of "B, C" to the right is controlled by the CRT controller control unit 2f.) Next, the half-width cursor is moved to the next input area using the cursor movement key "→".

FIG. 3c shows an example of correcting Hangul characters into alphanumeric symbols. First, when the half-width cursor is moved to the character to be corrected, "〓" using the cursor movement key "←", the half-width cursor becomes a full-width cursor. Next, when you enter the alphanumeric symbol "A", the display changes from the Hangul character "〓" to "A".
Move "B, C" to the left by a half-width amount, and the full-width cursor becomes a half-width cursor and is displayed at the B position.

In the case of a full-width cursor, the CRT controller control unit controls the cursor so that it moves two half-width characters with one cursor operation.

(Effect of the invention) As explained above, since Hangul characters are displayed in full-width size and alphanumeric symbols are displayed in half-width size, a large number of characters can be displayed. Since the characters are displayed when they are completed, no extra display area is required, and input characters can be corrected with simple cursor control. Furthermore, by using this function, it can be applied to Hangul World Processor and personal computers.
