Abstract

PURPOSE:To facilitate easy production, correction and evaluation of a pattern, by displaying patterns having different unit regions designated by character codes on the same screen and therefore recognizing the mutual relations among continuous unit matrixes. CONSTITUTION:A CRT controller 7 controls a CRT display 8, a display controller 9, a character generator 10, a refresh memory 11 and a refresh memory controller 12 respectively. The controller 9 processes the pattern signal sent from the generator 10 in accordance with display control signals of luminance, inversion, underlines, blinking, etc. which are stored in the memory 11. Then this processed output is supplied to a CRT display 8 to deliver a display pattern. The display pattern on the screen of the display 8 is scrolled for each dot row or column. Thus the patterns of continuous unit regions are displayed at one time.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pattern processing method for editing, such as creating and modifying display patterns of characters, symbols, etc. in a dot matrix configuration.

Conventionally, in a device that has the function of creating or modifying a display pattern of characters, symbols, etc. with a dot matrix structure while displaying it on a display device such as a CRT, when a single display pattern is obtained by combining multiple unit dot matrices, However, due to the limitations of the display method of the display device, the display pattern is generally created by dividing it into unit dot matrices and then performing modification. For example, as shown in Figure 1, the unit dot matrix is 7 dots vertically x 5 dots horizontally.
・If i is composed of dots (MPI, MP2), if you try to obtain a "row" by combining MPI and MP2,
By specifying the character code A that corresponds to MPI on the character processing device, create a pattern corresponding to the character code A on the display device, and then specify the character code corresponding to MP, 2. do.

Create a display pattern for ``TE'' which is the right half of ``1 line''. When created according to this method.

The MPI and MP2 display patterns had to be created independently, and there was a disadvantage that it was difficult to separate the mutual relationships between successive unit dot matrices.

Furthermore, when displaying the created patterns for evaluation or modification, it is necessary to repeatedly specify multiple codes, even though these patterns are stored in consecutive storage areas.

The present invention has been proposed in view of the disadvantages of the conventional method, and its purpose is to scroll the display pattern in units of dot rows or columns on the display screen of a display device, and to create patterns in continuous unit areas. can also be displayed at the same time, and the relationship ia! between the patterns (unit dot matrix) stored in the unit area. The aim is to facilitate understanding.

(9) Another object of the present invention is to enable continuous patterns to be scrolled and displayed in a specified unit area by specifying one putter/code, thereby eliminating the need for specifying multiple codes to recognize the relationship between unit dots and i-trixes. The purpose of this invention is to propose a pattern processing device that does the following.

The present invention will be described in detail below with reference to the drawings.

FIG. 2 shows an example of the configuration of the pattern processing device of the present invention, where 1 is a microphone processor, 2 is an address bus for specifying the address of each input/output memory, and 3 is a bidirectional bus used for transferring various data. data bus, 4 reads and writes each memory, etc., and accepts interrelated data.

The pattern signal from O is processed according to display control signals such as brightness, inversion, underline, and blinking stored in the refresh memory 11, and the processed output is sent to CR.
The signal is supplied to the T display device 8 to output a display pattern. The character generator 10 sequentially outputs, among the stored character patterns, character patterns for round strokes designated by input codes such as character codes and character pattern line addresses. Refresh memory XL
*.

Character codes and display control codes to be displayed on the CRT display device 8 are stored, and the character codes and display control codes are repeatedly displayed in response to display instructions from the CRT controller 7. The refresh memory controller 12 controls the above-mentioned refresh and cycle for CRT display and the writing and reading of data from the microprocessor 1 in accordance with instructions from the CRT controller 7. This is a read-only memory, ie, a so-called ROM, in which the control procedure shown in FIG. 4 is stored, as well as the processing procedure for each exercise. 14 is a ROMI 3 controller.

Reference numeral 15 denotes a random access memory, or RAM, which is used for temporarily storing various data.

For example, as a function of RAMI 5, there is a cursor register CR that stores cursor position data on the display screen.

A custom character buffer GB% stores display patterns of characters, symbols, etc. created in advance in the order of their codes, and a custom character code buffer GC stores the codes of the display patterns.
It is provided with a point address PA etc. for storing display start column ff information of a display pattern. 16a RAM 15 controller.

Next, an example of a specific configuration and arrangement of the keyboard 5 is shown in FIG. In the illustrated configuration, 5A is a group of character symbol keys consisting of alphabet keys, katakana keys, or expansion plate name keys, etc., and 5B is a group of cursor movement keys that instruct the movement of the cursor in the vertical and horizontal directions.% 5
B-1 is a right movement key that moves the cursor one character to the right,
5B-2 is a left movement key that moves the cursor one character to the left. 5A-1 is a pattern creation key for starting custom character processing.

5A-2 is a non-character processing end key for ending the processing.

FIG. 4 shows a control 70- executed by a control program stored in the ROM 13. In the following description, an example of the expanded unit dot matrix structure is 7 dots vertically by 5 dots horizontally. Therefore, the display on the CRT display screen in FIG. 2 is limited to a display range of 7 dots vertically by 5 dots horizontally, as shown in FIG. First, in step S1, the state of the pattern creation key 5A-1 is checked, and if the key is not pressed, other processing is executed in snap S9. Thereafter, the state of the key is checked again at Sl. When the pattern creation key 5A-1 is pressed, a code to be newly created or modified is set in the fifth step S2. Code setting is keyboard 50
By pressing a group of character symbol keys, the data is stored in the external character code buffer GC of RAMI Sl.

Figure 6 shows the storage patterns "row" and "stop" in RAMI Sl's external character buffer 7GB and their character codes r7FJr80.
It is a figure for explaining Jtr81Jr82J. now,
Assuming that the input from keyboard 5 is "80",
External character code buffer ac'ttc Input character: l-
)"[80JK!5On the display screen of the CRT8, "TE", which corresponds to the character code "80" in L in FIG. 6, is displayed as shown in FIG. FIG. 7 is a diagram for easily explaining the state of point address PA of RAMI Sl by associating it with the aforementioned external character buffer GB. In this example, the data at point address PA is P(1),
There are five types: P(2), P(3), P(4) and P(5), and in the case of P(1), it indicates the left edge of the display screen,
Assume that they move to the right in order, and P(5) indicates the right end. In the above case, P(1) is set in PA.

Note that this is the cursor 20a in FIG.

Next, in step S3, the display pattern shown in FIG. 5 is created and edited using another key.

However, at this stage, as can be easily seen from FIG. 5, the display pattern for the character code "80" only displays the right half of the "line". Therefore, the Z that is currently being created
dTo check whether the character pattern "line" you are modifying has been created correctly, enter the character code "7".
It is necessary to check the continuation of the pattern between FJ and "80". This request is resolved as follows.

First, by pressing cursor 5B on keyboard 5,
Move the cursor to 20 in FIG. 5 (left end of the display screen). In this state, if the left movement key 5B-2 is further pressed, that is, the left movement key 5B-2 is pressed in a state where the cursor cannot be moved to the left any further on the display screen, the process 74-chard moves to the right in step s4. It is determined that screen processing will be performed,
Control proceeds to step S5. In step 5, R.A.
The value stored in point address PA in M15 is changed from character code 80 p (i) to character code 7F P (
5) and subtract 1'' from the value of the character code 8o stored in the external character code buffer GC. ・Newly change "7F" to the external character °-Dova software GCt.
Set C. Therefore, it is determined by the value of the table address PA at this time. In this case, GCr 7FJt! :
PArP (5) JjC1 display h/-n is "7F" in Figure 7.
” area r P (5) J to “80” area “
P(4)". As a result, display pattern line 8
As shown in the figure, the right Vcl dot is scrolled and displayed.

If you have finished creating or editing the pattern at this stage,
The process ends by pressing the external character processing keyboard 5A-2 in the keyboard 5. If additional creation or modification is required, control is returned to step S3 (step S8), and the same process is completely returned.

If you want to further scroll the display pattern to the right,
As before, with the cursor set at the left end, each time the left movement key is pressed, the value of point address PA is sequentially decreased from P (4) to P (3) to P (1). Executed by Also, step 86
, 87 display pattern is shifted to the left, and it goes without saying that the operation line is the opposite of the case of right shift described above. Press the cursor right movement key 5B-1 to move the cursor to the right end of the display screen as shown in FIG.
When B-1 is pressed, the control unit determines that left scroll processing is to be performed in step S4, advances the control to step S6, and updates the point address PA in the RAM 15 to the character code 810P (1) in step S7. , sets character code 81 to external character code buffer 7GC.

In this way, by repeating steps 83 to 88, adjacent character codes can be shifted and displayed in succession.

In the embodiment described above, the character structure was set to a 7 x 5 dot matrix structure, but this structure is a 24 x 2 dot matrix structure.
4. Alternatively, a dot configuration of 32 x 32 holes may be used.

Furthermore, by configuring adjacent character codes two-dimensionally as shown in FIG. 11, for example, character codes 7F, 81, 60,
It is clear that scrolling is possible for 100 display patterns using the same method as described above.

As described above, according to the present invention, patterns in which the unit areas designated by one-character codes are different are displayed on the same screen, so that the mutual relationship between consecutive unit matrices can be recognized. Therefore, creating, modifying, and evaluating patterns becomes easy. Furthermore, reading out a pattern spanning a plurality of unit areas can be realized by designating one character code, making the display operation on one screen extremely simple.
