Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pattern creation processing method, particularly to creating a dot pattern for a pattern display device that displays a character pattern by turning on/off dots such as 16 x 16 or 24 x 24 dots. In this case, one dot is enlarged to display one character, and a dot pattern based on divided and input pattern data is immediately displayed at the size actually displayed on the display device, This invention relates to a pattern creation processing method that facilitates the design and creation of patterns.

For example, in CRT display devices,
Characters (including symbols and codes; the same shall apply hereinafter) are expressed and displayed as connections between many meaningful dots. Particularly recently, many Japanese language processing devices have become widespread, and kanji characters with complex patterns are now expressed using dots. Furthermore, in order to enable precise expression of the number of dots for one character, a large number of dots, such as 16 x 16, 24 x 24, 30 x 30 dots, etc., are being assigned. Designing and creating this dot pattern requires a lot of time and effort, but the dot pattern that is created and actually displayed often differs from the originally intended image, so an appropriate dot pattern for a certain character is determined. It often takes several trials and errors to get it right.

However, when creating a conventional dot pattern,
Even if you design a dot pattern and enter pattern data, you cannot immediately display the dot pattern at the actual display size, and it may be displayed on a different device than the one on which it is actually displayed, such as a printing device. I was asked to go over and check the design. Therefore, even after the design has been confirmed, if the created dot pattern is displayed on the device that will actually be used, the resulting image will be different from the one at the time of design, and furthermore, the dot pattern cannot be easily corrected. There was a drawback.

Therefore, an enlarged area corresponding to the number of dots (vertically and horizontally) of the real character pattern is displayed on one screen, and the real character pattern corresponding to the pattern specified in the enlarged area by light pen operation is displayed at the same time. Patterns have been created, but there has been a problem in that, especially when the number of vertical dots is greater than the number of lines displayed on one screen, the enlarged area cannot be displayed, making it impossible to create dot patterns.

The present invention aims to solve the above problems by dividing the input area even when the number of dots is greater than the number of display lines on one screen, thereby making it possible to display the actual dot pattern based on the input pattern data. The purpose of this invention is to provide a method that allows patterns to be efficiently created or modified in a conversational manner while viewing the displayed results. For this reason, the pattern creation processing method of the present invention uses a character generator to generate and display a pattern of dots corresponding to a character code stored on a screen code buffer. A character generator that can write, an input area where each dot of the dot pattern to be created corresponds to the display of one character, and an input area that is divided into multiple parts when displayed on the display. a pattern data input processing unit having means for switching and displaying, and inputting a predetermined character written in an input area switched and selected by the switching means as pattern data for a specified character code; It is equipped with a dot pattern creation processing section that creates a dot pattern of an actual size character based on the pattern data written in the input area divided into a plurality of parts, and writes it into the character generator. The present invention is characterized in that a part of the input pattern data and an actual size dot pattern based on the entire pattern data are displayed together.

This will be explained below with reference to the drawings.

FIG. 1 is a diagram for explaining a display mode that is a premise of the present invention, and FIG. 2 is a diagram illustrating an example of a display mode of a display screen according to the embodiment of the present invention. In the figure, 1
is the display screen of the display, 2 is the input area where the input pattern data is displayed, 3 is the input pattern data, 4 is the display area where the actual size dot pattern based on the input pattern data 3 is displayed, 5 is the dot pattern represents. In addition, in the embodiment described below, the display device is
It shall have a display function of 40 characters x 24 lines.

For example, one character pattern such as kanji is 24×24
In a display device composed of dots,
When creating a new kanji dot pattern,
As shown in Figure 1, the display screen 1 is 24
It is logically divided into an input area 2 for 24 lines of characters and a display area 4 for one character, that is, 24 x 24 dots.
The input pattern data 3 is displayed as an enlarged image in which one dot corresponds to one character. Also,
In the other display area 4, the dot pattern 5 corresponding to the input pattern data 3 is displayed in the actual size immediately after the input pattern data 3 is input. In the example shown in FIG. 1, the input pattern data 3 in the input area 2 is composed of characters "". Therefore, display area 4 corresponding to the position where the character "〇" is input
The dot is turned on. That is,
For example, the pattern creator moves the cursor to a desired position in the input area 2 by pressing the cursor movement key on the keyboard of the display device, presses the input key for the character "〇", and inputs the input pattern data. Just enter 3. that way,
The character "O" is displayed at the position of the cursor when the input key is pressed on the display screen 1, and a dot is added and displayed at the corresponding position in the display area 4. Therefore, the pattern creator, while looking at the actual size dot pattern 5 in the display area 4,
You can modify and add patterns. If the dot pattern 5 displayed in the display area 4 is not appropriate and you want to erase some of the dots, move the cursor to the position of the input pattern data 3 in the input area 2 that corresponds to the dot you want to erase. Just move it and press the delete key.
As described above, according to the example shown in FIG. 1, the input result of pattern data is immediately displayed in the actual size, and corrections and additions are also easy, making it possible to efficiently create patterns for kanji characters, etc.

If one character pattern on the display device is composed of, for example, 30 x 30 dots, the size of display screen 1 is 40 characters x 24 lines, so it corresponds to 30 x 30 dots in display area 4. The input area 2 of 30 characters x 30 lines cannot be secured at one point in time. Therefore, in the present invention, the input area 2 is divided as shown in FIG. It is possible to switch with . That is, when the pattern creator specifies the upper input area 2, the upper 30 x 24 dots of the 30 x 30 dots in the display area 4 as shown in Figure 2A.
Input area 2 of 30 characters x 24 lines is allocated to correspond to the dots, and if the pattern creator specifies lower input area 2, the lower 30 x 24 dots of display area 4 as shown in Figure 2B. Even if the input area is switched as described above, the display area 4 will commonly display the dot pattern 5 corresponding to one character. The creator will not be confused when modifying or adding input pattern data 3.

FIG. 3 shows the configuration of an embodiment of the present invention. In the figure,
6 is a data processing device, 7 is a pattern data input processing section, 8 is a dot pattern creation processing section, 9 is a data bus, 10 is a cursor address register, 11
is the keyboard, 12 is the character generator,
13 represents a screen code buffer, 14 represents a parallel/serial converter, and 15 represents a CRT display.

The screen code buffer 13 is composed of a refresh memory whose size corresponds to the size of the display screen of the CRT display 15, and stores character codes to be displayed on the screen. The character generator 12 has a writable memory that stores dot patterns to be displayed for each character code, and generates characters with corresponding dots based on the character code stored in the screen code buffer 13. Generate a pattern. The keyboard 11 is an input device used in conjunction with a CRT display 15 for input by an operator. The cursor address register 10 is a register that holds the position of the cursor displayed on the screen of the CRT display 15, and is updated to an appropriate value by keying in from the keyboard 11 so that the cursor can be moved.

When designing and creating a new character pattern, the pattern creator specifies the character code corresponding to the character pattern to be created from the keyboard 11, and notifies the data processing device 6 that the pattern will be created. do. For example, if the character is a Kanji character, 2 bytes are prepared for this character code, and when creating a new character pattern, it is necessary to specify a code that is not normally used. When the pattern creator instructs the pattern creator to create the pattern, the pattern data input processor 7 of the data processor 6 has a work area (not shown) for storing input pattern data therein.
At the same time, the screen code buffer 13 is cleared and initial settings are performed, and the frame of the input area 2 divided into the screen code buffer 13 is set and displayed. Then, the specified character code corresponding to the character pattern to be created is stored in the screen code buffer 13 at a position corresponding to the display area 4 explained in FIG. 2. This character code is input to the character generator 12 by scanning the screen code buffer 13, but before inputting the pattern data, all dots are off and no dots appear on the screen of the CRT display 15. No display will be made.

When the initial setting by the pattern data input processing section 7 is completed, the pattern creator presses the cursor movement key on the keyboard 11 and moves the cursor to an appropriate position in the input area 2 as explained using FIG. Then, for example, press the character "〇" key to input pattern data. This character “〇”
The input character code is stored in the screen code buffer 13 at a position corresponding to the cursor address at that time, and is input to the pattern data input processing section 7. The pattern data input processing section 7 reads the contents of the cursor address register 10, recognizes the current cursor address, sets the input pattern data and the row data and column data of the cursor address in an internal work area, and creates a dot pattern. Control is passed to the processing unit 8. The dot pattern creation processing unit 8 calculates the dot position to which the input pattern data corresponds, for example, in a 30×30 dots matrix formed by combining the input areas, based on the data in the internal work area. Dot pattern data for actual size characters of 30 x 30 dots is created based on the calculation results.
This created dot pattern data is written to the character generator 12 via the data bus 9. When writing, the character code corresponding to the dot pattern data is also transferred.
WRITE signal is provided. That is, it can be considered that this character code becomes the address of the internal memory where the dot pattern of the character generator 12 is stored.

As described above, by writing the dot pattern corresponding to the input pattern data into the character generator 12, the screen code buffer 13
Since the character codes stored in the display area are sequentially scanned and input to the character generator 12, a new dot pattern for the character code for the display area can be immediately generated by the character generator 12. becomes. In this way, the screen data of the input area 2 and display area 4 shown in FIG. This will be displayed on the display screen 1 as shown in FIG.

As explained above, according to the present invention, even if the number of vertical dots is greater than the number of display lines on one screen, it is possible to always see the state of the dot pattern actually displayed at that time while inputting data. This makes it possible to create patterns more easily and efficiently in a conversational format.
