Description

[Detailed Description of the Invention] This invention is used in display devices connected to various data processing devices such as word processors, office computers, DPS (data processing systems), and output devices such as printers. The present invention relates to a pattern generation device suitable for generating I! of normal character patterns, especially when a Japanese word processor uses many types of characters, including kanji, and their sizes are also diverse. ! ! There is no need to increase the storage capacity of the pattern storage means that stores one-character pattern data by tracing the contours.
The present invention relates to a pattern generator capable of displaying and printing a white character pattern.

Specifically, from a normal character pattern commonly used in data processing devices, that is, basic character pattern data consisting of a dot array, a white pattern is generated by modifying the pattern data. The present invention relates to a pattern generation device that can display and print white patterns, thereby diversifying the types of character patterns that can be used and creating documents that are visually beautiful and easy to read.

Conventional Arashi word processors, office computers, and other data processing devices are connected to CRTs, LCDs, and other displays, and operators input desired data while interacting with the CRT screen. Processing and creating documents, tables, etc.

In this case, the processed data can be displayed on the screen,
In order to print documents and the like based on created data, a character generator that stores character pattern data, a pattern memory that stores font data, and the like are used.

FIG. 5 is a functional block diagram showing an example of the main part configuration of a conventionally used data processing device such as a word processor. In the drawings, 1 is a central processing unit, 2 is an input device, 3 is a system memory, 4 is a CRT controller, 5 is a video memory, 6 is a CRT, 7 is an external storage device, and 8 is a printer.

In data processing systems such as Japanese word processors,
As shown in FIG. 5, a central processing unit 1, an input device 2
, a system memory 3 as a main storage section, an external storage device 7 as an auxiliary storage section, and a printer 2581 that performs printing as an output section.
It is equipped with a CRT 6, a video memory 5, a CRT controller 4, etc. for display.

The functions of each part of the data processing apparatus shown in FIG. 5 are as follows.

The central processing unit 1 includes a CPU, ROM and RA that store programs and other data that control the entire system.
It is a central processing unit that controls the entire data processing system. This central processing unit 1 is equipped with a character generator (not shown) or phonographs 1 to 1 stored in an external storage device 7 in order to convert input character codes into dot pattern data during display or printing. Character pattern storage means such as a pattern memory is provided for loading data.

The input device 2 includes a keyboard and has an input function for inputting character information, control information, and the like.

The system memory 3 is a storage device used for work.

The CRT controller 4 controls the video memory 5 and the CRT 6, and performs controls necessary for display operations, such as generating horizontal and vertical synchronizing signals and writing display data.

For example, when outputting a character pattern to CRT6,
The character code data stored in the video memory 5 is C
It is read out in synchronization with the scanning timing of RT6 and converted into dot data. In this case, the character pattern is displayed as a bright dot with a logical "1" bit indicating that the dot data is on. In addition, the character position on CRTS is
It is uniquely determined by the address of the video memory 5.

The external storage device 7 is, for example, a storage device such as a floppy disk or a large-capacity magnetic disk.

The printer 8 is one of the output devices, and converts character code data stored in the system memory 3 or external storage bag fi7 into dot pattern data stored in a character generator, etc., and outputs it as dot data. given and operates to create a hard copy.

A data processing device such as a word processor or an office computer has a configuration as shown in FIG. 5, and performs various data processing through input operations on the input device 2.

However, in the case of systems such as Japanese word processors, there are many types of characters used, so just storing normal character pattern data requires a larger capacity pattern storage means than in the case of Roman word processors. . If pattern data for white characters is added on top of that, the storage capacity will become even larger.

Therefore, the outline of a single character pattern is displayed as bright dots or printed as black dots.

In order to use so-called white pattern characters, in which the inner part is expressed with non-bright spots or white, a large capacity pattern data storage means is required, especially in the case of 1 Japanese word processors etc., which is expensive. It will be disadvantageous.

Therefore, in conventional systems such as Japanese word processors, when using white characters, a pattern is created by cutting out the inside of a normal character font.

However, with this pattern creation method, the dot width (the length is also the same) of the lines or dots that make up the character pattern.
However, since at least three dots are required, outline characters can only be created when using characters that have a large number of dots, such as enlarged characters.

As shown in 2, the conventional method of creating a white character pattern is
There is an inconvenience that character patterns that are commonly used, that is, basic character patterns, cannot be simply implemented.

■ = - flag Therefore, the pattern generator of the present invention solves the inconveniences that occur in conventional data processing systems such as Japanese word processors, especially the inconveniences in the method of generating white patterns, and uses means with a simple configuration. A modification that traces one outline of the basic character pattern data that is stored in the character generator or in the pattern memory as font data, that is, the pattern data of a normal character composed of an array of dots. By performing processing to generate white pattern data, it is possible to display and print visually beautiful and diverse character patterns without increasing the capacity of the character pattern storage means. purpose.

With such a configuration, it is possible to trace the outline of the dots that constitute the original pattern of a certain character, and the modification process of the original pattern can be realized.

More specifically, regarding the data of dot patterns constituting one basic character, that is, the original pattern of one character, the original pattern can be divided into, for example, upper, lower,
Patterns obtained by shifting in four directions, left and right, are created, and patterns at the beginning of the shift in the four directions are combined (OR) processed to create one composite pattern. Then, by performing an exclusive OR of this composite pattern and its original pattern.

A white pattern is created by modifying the original pattern.

In this case, the compositing (OR) process not only shifts the original pattern in four directions: top, bottom, left, and right, but also shifts the original pattern in a total of 8 directions, including top, bottom, left, right, top left, top right, bottom left, and bottom right. It is also possible to use a composite pattern in which all patterns shifted in eight directions are combined.

The pattern generation device of the present invention has a function of controlling the process of extracting pattern data from the pattern storage means for storing data of this character pattern, its composition, exclusive OR process, etc., that is, the function of generating a modification pattern. This is realized using pattern conversion means.

Next, embodiments of the pattern generator of the present invention will be described in detail with reference to the drawings.

This pattern conversion control unit 9 shifts the original pattern data at least upward, downward, left, and right, and synthesizes the data.
It also has a function of generating a modification pattern by exclusive ORing the synthesized data and the original pattern data.

The functions of each part are explained as follows.

The pattern memory 10 is a memory in which character patterns are stored, and is, for example, a character generator.

The input buffer memory 91 is a buffer memory that temporarily stores one character of pattern data taken out from the pattern memory 10.

The shift control unit 92 controls the pattern data taken out from the input buffer memory 91 according to the set mode, and shifts the data in one direction (up, down, left, right), or sends it out at all. Control is performed such that it is transmitted without shifting.

The pattern data that has passed through the shift control section 92 is given to the next write control section 93.

This write control unit 93 determines the method of writing to the output buffer 94 (upper three, combination, exclusive OR).

FIG. 2 is a flowchart showing a procedure for creating an outline character pattern in the pattern generating device of the present invention shown in FIG. In the drawings, #1 to #9 indicate each step.

The following FIGS. 3 (1) to (5) are memory diagrams showing an example of pattern data when creating a white character pattern of the number "1" by the pattern generator of the present invention.

(4) is a composite pattern with a pattern shifted by one dot in the downward, left, and right directions, (4) is a pattern after removing the outside of the matrix that makes up the original pattern in (1), (5)
) is a pattern obtained by performing exclusive OR processing on the pattern (4) and the composite pattern (3). Drawing (4)
The hatched area indicates the position of the dot to be removed in the matrix constituting the original pattern.

Next, with reference to FIGS. 2 and 3, a procedure for creating an outline character pattern using the pattern generator of the present invention will be described.

First, as shown in FIG. 2, in step #1, a character pattern of the number "1" as shown in FIG. 3 (1) is taken out from the pattern memory 10 and stored in the input buffer memory 91.

In step #2, the data temporarily stored in the input buffer memory 91 is copied to the output buffer memory 94. In this case, the processing mode of step #2 is a copy mode, the shift control unit 92 performs a process without shifting, and the write control unit 93 operates in an overwrite (MOVE) mode in which pattern data at the same position is written as is. The same character pattern as in Figure 3 (1) is created by processing
Write to output buffer memory 94.

Next, in step #3, while shifting the data in the input buffer memory 91 upward, the output buffer memory 94
and synthesizes it with the character pattern copied in step #2. That is, in this step #3, the shift control section 92 is set to the upper shift mode, and the write control section 9
3 is set to the combination (OR) mode. The pattern shifted up by one bit by the shift control unit 92 is shown in FIG.
), this pattern and the original pattern of FIG. 3(1) are combined and written into the output buffer memory 94.

In step #4, the data in the input buffer memory 91 is shifted downward and then combined with the pattern in the output buffer memory 94. The mode of this step #4 is basically the same as the previous step #3, but the shift control section 9
2 is the down shift mode.

In step #5, the data in the input buffer memory 91 is shifted to the left and then synthesized into the output buffer memory 94. This step #5 mode also applies to the previous step #5.
3, but the shift control unit 92 is placed in the left shift mode.

Similarly, in step #6, the data in the input buffer memory 91 is shifted to the right and then synthesized into the output buffer memory 94. The mode of this step #6 is also basically the same as the previous step #3, but the shift control section 92
is considered to be the right shift mode.

Through the processing of steps #1 to #6 above, pattern data as shown in FIG. 3(3) is stored in the output buffer memory 94.

In the next step #7, the data of the outermost dot in the input buffer memory 91 is removed.

This operation is performed in order to truncate the data when one or more dot data protrudes due to the shift process. The shaded tons 1 to 1 in FIG. 3(4) are the dots to be truncated. The pattern for which the removal process has been completed is stored in the input buffer memory 91.

In step #8, the data in the input buffer memory 91 shown in FIG. 3 (4) and the data in the output buffer memory 94 shown in FIG. It remains in the memory 94.

Therefore, the output buffer memory 94 has
) data with a white pattern is obtained.

In this step #8, the shift 1 control section 92 is in the no shift mode, and the write control section 93 is in the exclusive OR (X
OR) mode.

By the processing of steps #1 to #8 above, the character pattern of the number "1" in FIG. 3 (1) is changed to
) is obtained.

The character pattern completed through such processing is outputted from the output buffer memory 94 to the display device 6 or the printer 8 for display or printing in the final step #9.

Therefore, the character pattern displayed on the display device 6 in FIG. 1 or printed by the printing device 8 is as shown in FIG. 3 (1).
Instead of the original pattern of the number "1", an outline pattern as shown in FIG. 3 (5) is created.

In FIGS. 2 and 3 above, the case where an outline pattern of the number "1" is created has been described.

Next, the case of a kanji character with a complicated dot pattern arrangement will be explained.

FIGS. 4(1) to (4) are memory diagrams showing an example of pattern data when creating a white character pattern for the kanji "kan" by the pattern generator of the present invention, (1)
is the original pattern, (2) is the original pattern of (1), and the original pattern is shifted by one dot in four directions: up, down, left, and right.
- A composite pattern of the original pattern, (3) is a pattern obtained by removing one dot outside the matrix that constitutes the original pattern of (1), and (4) is a pattern obtained by removing one dot outside the original pattern of (2). This is a pattern obtained by performing an exclusive OR process on the pattern from which the above is removed and the composite pattern in (3). The symbol ``■'' in (2) of the drawing indicates a dot that existed in the original pattern among patterns that were synthesized by shifting the original pattern by one dot in four directions: up, down, left, and right.

The procedure for creating the white character pattern for the kanji character "Kan" in FIG. 4 is the same as that for the number "1" described above.

That is, in step #1 of FIG.
The character pattern of the alphabet "Kan" as shown in FIG. 4 (1) is extracted from 0 and stored in the input buffer memory 91.

In step #2, the data temporarily stored in the input buffer memory 91 is copied to the output buffer memory 94. The processing mode in step #2 is a copy mode, and the shift control unit 92 performs processing without shifting.
The write control section 93 performs overwrite (MOVE) mode processing to write a character pattern similar to that shown in FIG. 1 (1).

Next, in step #3, while shifting the data in the input buffer memory 91 upward, the output buffer memory 94
and synthesizes it with the character pattern copied in step #2.

In step #4, the data in the input buffer memory 91 is combined into the output buffer memory 94 without being shifted downward.

In step #5, the data in the input buffer memory 91 is shifted leftward and then synthesized into the output buffer memory 94.

Similarly, in step #6, the data in the input buffer memory 91 is shifted to the right and then synthesized into the output buffer memory 94.

Through the processing of steps #1 to #6 described above, pattern data as shown in FIG. 4(2) is stored in the output buffer memory 94.

In the next step #7, the data of the outermost driver 1- in the input buffer memory 91 is removed. Therefore, as shown in FIG. 4(3), the data in the area corresponding to the outermost one dot marked with diagonal lines is removed.

In step #8, ' is the input buffer memory 91 from which the data in the output buffer memory 94 shown in FIG. 4 (2) and the data in the outermost one dot area shown in FIG. 4 (3) have been removed. The result is left in the output buffer memory 94.

In the output buffer memory 94, data of a white pattern as shown in FIG. 4 (4) is obtained.

By the processing of steps #1 to #8 above, the character pattern of the kanji "kan" in FIG. 4 (1) is changed to
) is obtained.

The character pattern completed through such processing is outputted from the output buffer memory 94 to the display device 6 or the printer 8 for display or printing in the final step #9.

Therefore, it is displayed on the display device 6 of FIG.

Or the character pattern printed by the printing device 8.

This results in a white pattern as shown in FIG. 4 (4).

In addition, in the above embodiment, the dots constituting one character are
The case of 24x24 (dot configuration) has been explained.

However, it is not necessarily necessary to have a 24x24 C dot configuration, and other dot configurations may also be used.
Needless to say, it can be implemented in the same way.

In addition, the shift processing by the shift control unit 92 includes up, down,
The cases in which it is performed in four directions, left and right, have been described in detail.

However, not only these four directions, upper, lower, left, and right, but also upper left, lower left, and upper right.

It is also possible to shift in the four directions at the bottom right, for a total of eight directions, not necessarily up, down, or left.

It is not limited to the four directions on the right. This shift processing to h F ′: +, ′, H is, for example,
As in 32'x:32 (dot composition) or 48x48 (dot composition), if the number of dots 1 to 1 to form one character 11゜4 increases, a remarkable effect can be obtained.

As described above in detail, the pattern generation device of the present invention includes a pattern storage means for storing data of a single character pattern, and original pattern data taken out from the pattern storage means at least at the top and bottom.

pattern conversion means having a function of synthesizing by shifting left and right, and a function of generating a modification pattern by exclusive OR of the synthesized data and the original pattern data;
It consists of

Therefore, according to the pattern generator of the present invention, there is no need to increase the capacity of the character pattern storage means, and data of a white pattern can be generated by a modification process that traces the outline of the pattern data of a normal character. can be produced,
It looks beautiful and can display and print in a variety of character patterns.

Moreover, the modification process for generating data for such white patterns can be performed regardless of the character size, so the more types of character sizes used in the data processing system 11, the more the character pattern The savings in storage means capacity is also greater.

This excellent effect can be obtained.
