Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing apparatus which receives a character code and outputs a character pattern in a document preparation system such as a word processor.

[0002]

2. Description of the Related Art In a document preparation system such as a word processor, a character code is obtained from a dictionary memory by an operator's key input operation, a character pattern is generated in the character processing device from the character code, and the character pattern is generated by the character processing device. Is output to the output buffer and the characters are displayed on the display.

In a document creating system such as a word processor, a character processing device 1 that receives a character code and outputs a character pattern is generally used by the character processing device 1 as shown in FIG. Is configured to be integrally and subordinately controlled with respect to the higher-level processing device 2 including a part that generates a character code and a part that displays a character on the display by a character pattern from the character processing device 1. .

By the way, in such a document creating system, ligature processing and ligature processing are often performed. The ligature process is a process of converting a specific character string into a character composed of one character by design, for example, the English word "differ".
The character string "ff" as shown in FIG.
Replacement character (character after replacement) as shown in (B)
To replace. In addition, ligature processing is the process of creating multiple characters (including symbols and figures) when creating European languages.
Is combined to form one character as shown in each of FIG.

Furthermore, when each character is originally composed of a plurality of character elements selected from a large number of character elements such as Hangul characters, each of the selected character elements is combined to form each character element. The process of forming characters is often done.

In the conventional document creating system, a ligature table in which ligature processing information is written is prepared separately from the character font data in the character processing apparatus 1 described above, and the character processing apparatus 1 is operated by the host processing apparatus 2. The ligature process is performed by controlling. The same applies to ligature processing.

Further, in the case of processing for forming each character by combining a plurality of character elements for Hangul characters as described above, it is impossible to specify the character until all the character elements constituting the character are prepared. Therefore, in JP-A-56-65282, an input buffer for storing sequentially input character element codes is provided, and a character is specified based on the input order and contents of the character element codes stored therein, and a character pattern is determined. A method of forming is disclosed.

[0008]

However, in the above-described conventional document creating system, the character processing device 1 which receives a character code and outputs a character pattern is controlled integrally and subordinately to the upper processing device 2. Since the character processing device 1 is controlled by the higher-level processing device 2 even in the ligature process and the ligature process, the character processing device 1
Even if the processing information of the ligature processing or the ligature processing is prepared, the ligature processing or the ligature processing is not performed depending on the configuration or control information of the higher-level processing device 2, and the obtained document is different even though it is the same document. There are some drawbacks.

[0009] Hangul characters are disclosed in Japanese Patent Laid-Open No. 56-6.
Also in the method disclosed in Japanese Patent No. 5282, the upper processing device 2 must be compatible with all combinations of character elements, and when adding or changing a character, the configuration or control information of the upper processing device 2 is required. Has to be changed, which makes it difficult to add or change characters after the high-order processing device 2 is completed.

However, recently, as a document creating system such as a word processor, as conceptually shown in FIG. 14, a character processing device 1 which receives a character code and outputs a character pattern is independent of a host processing device 2. It is considered that the character processing device 1 has an independent function with respect to the higher-level processing device 2 in the ligature process and the like. It is possible to avoid inconvenience.

Therefore, according to the present invention, the character processing device of the document creation system can independently perform the ligature process and the like, so that the ligature process and the like can be reliably performed regardless of the configuration or control information of the upper processing device. In addition to being able to obtain a character output of the same quality, it is possible to easily add or change a character string or character element string to be subjected to ligature processing or a replacement character.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of a character creating system having an example of a character processing device according to the present invention.
Is to receive a character code from the upper processing device 20 of the document creation system and output a character pattern to the upper processing device 20. In this example, the character data reading means 11, the character data storage means 12, and the character data temporary storage means are provided. 13, a replacement processing unit 14, a pseudo character data generation unit 15, and a character pattern generation unit 16.

In the host processor 20, the interpretation / editing means 21
Interprets a key operation on the input means 22, reads the character code from the character code storage means 23, performs an editing process, and sequentially outputs the character code to the character processing device 10.

Character data reading means 1 of the character processing device 10
1 reads out the following character data stored in the character data storage unit 12 from the character data storage unit 12 according to the character code from the interpretation / editing unit 21 of the upper processing unit 20.

That is, in the character data storage means 12,
Character data corresponding to the character code is stored in advance. However, character data refers to a character that is processed by the character alone, and a replacement character or a pseudo character whose character string is a specific character when the character is followed by a specific character or characters. About the character when it is replaced with a pseudo replacement character that is one character,
Divided into two. For a character that is processed by itself, as a character that does not have a subsequent list, it is assumed that it has only character font data for generating the character pattern of that character. When the character string is replaced with a replacement character or a pseudo replacement character, specific replacement information is added to the character font data as a character having a subsequent list.

FIG. 4 shows an example of the character data.
(A) is character data for "d", which is a character that does not have a subsequent list. For the outline font data O (d) of "d", the character code of the subsequent list, the character code of the replacement character, and The coordinate conversion matrix for generating the pseudo replacement character is added as a tag field. On the other hand, FIG. 4B shows the character data of "f" which is a character having a succeeding list. The outline font data O (f) of "f" is replaced with the character code of the succeeding list. The character code of the character and the coordinate conversion matrix for generating the pseudo replacement character are added.

However, in this example, the character is "f".
"F", "fi", "fl" as the subsequent characters respectively
When “i” and “l” are continued, the FIG.
Character strings "ff", "ffi", and "ff" as shown in (A)
Finally, “l”, “fi”, and “fl” are respectively shown in FIG.
~ When replaced with a replacement character as shown in Fig. 9B, the character data of the character "f" is therefore replaced by the character string "ff", "ffi", "ffl", "fi", "fl". The character code of the list, the character code of the replacement character, and the coordinate conversion matrix for generating the pseudo replacement character are included. C (f), C
(I) and C (l) are the characters "f", "i", and "l", respectively.
Is a character code of C (ff), C (ffi), C
(Ffl), C (fi), and C (fl) are shown in FIG.
It is the character code of the replacement character as shown in (B) to FIG. 9 (B).

The coordinate conversion matrices M1 and M2 are coordinate conversion matrices for performing coordinate conversion on the character data of each character of the character string to generate character data of the pseudo replacement character, for example, in the x direction and It is a 3 × 3 matrix composed of coefficients related to coordinate values in the y direction and movement amounts in the x direction and the y direction.

For example, the coordinate transformation matrix M1 is as shown in FIG.
As shown in 0 (A), the coordinate value in the y direction remains unchanged and x
The coordinate value in the direction is set to 1/2 and the amount of movement in the x direction and the direction in the y direction is set to zero. By the coordinate conversion represented by the formula shown in FIG. The first character "f" of the character string "ff" as shown in (A) is compressed to 1/2 in the x direction as shown in the left half of FIG. 11 (B). Further, in the coordinate conversion matrix M2, as shown in FIG. 10 (C), the coordinate values in the y direction are unchanged, the coordinate values in the x direction are halved, the amount of movement in the y direction is zero, and the amount of movement in the x direction is zero. Is set to ½ of the unit width, and the coordinate conversion matrix M2 shown in FIG.
By the coordinate conversion represented by the formula shown in FIG.
The character "f" after the character string "ff" as shown in (A)
Is 1 / x in the x direction at a position offset by 1/2 of the unit width in the x direction as shown in the right half of FIG.
Compressed to 2.

Although not shown in FIG. 4, each outline font data is also stored in the character data storage means 12 as the character data of the replacement character as shown in FIGS. 5 (B) to 9 (B). It

The configurations and functions of the character data temporary storage means 13, the replacement processing means 14, the pseudo character data generation means 15 and the character pattern generation means 16 will be described below with reference to FIGS. 2 and 3. The line indicated by a thick arrow in FIG. 1 is a control line.

The character pattern temporary storage means 24 of the upper processing device 20 is a character pattern (character pattern data) obtained from the character pattern generating means 16 of the character processing device 10.
The display means 25 is a display such as a CRT display for displaying characters according to the character pattern from the character pattern temporary storage means 24.

Hereinafter, the character strings "bull" and "di" will be specifically described.
The operation of the above-described character processing device 10 will be described with reference to FIGS. 2 and 3, taking as an example the case where the character codes “ffer” and “difficult” are input from the higher-level processing device 20 to the character processing device 10.

First, the case where the character code of the character string "bull" is input to the character processing device 10 will be described. However, this example is a case where none of the characters "b", "u", and "l" has a subsequent list.

When the character code of the character "b" is input to the character data reading means 11, the character data of the character "b" is read from the character data storage means 12 (step S
1) The character data is stored in the character data temporary storage means 13 (step S2).

Next, it is judged whether or not replacement information is stored in the replacement processing means 14 (step S).
3). However, the character "b" is the first character of the character string "bull", and as will be apparent from the later description, since the replacement information is not stored in the replacement processing means 14 at this time, the character "b" is further changed. It is determined whether or not the character has a subsequent list (step S15).

Since the character "b" is a character having no subsequent list, the character data temporary storage means 13 sends the character data (outline font data) of the character "b" to the character pattern generation means 16 next. The character pattern generation means 16 generates a character pattern (character pattern data) of the character "b" and outputs it to the higher-level processing device 20 (step S10). In the host processor 20, the character pattern is stored in the character pattern temporary storage means 24, is sent from the character pattern temporary storage means 24 to the display means 25, and the character “b” is displayed on the display means 25.

The remaining characters "u" of the character string "bul"
Since "l" and "l" do not have a trailing list like the character "b", even when the character codes of the remaining characters "u", "l" and "l" are sequentially input to the character data reading means 11, For each character, the character data is read from the character data storage means 12 (step S1), and the character data is stored in the character data temporary storage means 13 (step S1).
2), and the character pattern generation means 16 sequentially generates and outputs a character pattern (step S10). In this way, the character string "bull" is displayed on the display unit 25 without any replacement.

Next, the case where the character code of the character string "differ" is input to the character processing device 10 is shown. Since the characters "d" and "i" have no subsequent list, the character code of the characters "d" and "i" is the character data reading means 11
When the characters are sequentially input to, the character data is read from the character data storage means 12 for each character (step S1), the character data is stored in the character data temporary storage means 13 (step S2), and the character is stored. Generation and output of a character pattern by the pattern generation means 16 (step S1
0) is sequentially performed, and the character string "di" is displayed on the display unit 25.

The character "f" after the character string "di" has a successor list and is therefore replaced. That is, the character code of the character “f” is the character data reading means 11
When first input is, the character data of the character "f" is read from the character data storage means 12 (step S1),
The character data is stored in the character data temporary storage means 13 (step S2), and it is determined whether or not the replacement information is stored in the replacement processing means 14 (step S).
3). The character "i" before the character "f" is a character that does not have a subsequent list, and since the replacement information is not stored in the replacement processing means 14 at this time, the character "f" is a character that has a subsequent list. It is determined whether or not (step S15).

Since the character "f" is a character having a subsequent list, the character data of the character "f" in FIG.
The replacement information as shown in, that is, the character code of the subsequent list, the character code of the replacement character, and the coordinate conversion matrix for generating the pseudo replacement character is stored in the replacement processing unit 14 (step S16).

Next, the outline character font data O (f) of the character "f" and the coordinate conversion matrix M1 are transferred from the character data temporary storage means 13 to the pseudo character data generation means 15.
Is transmitted, the pseudo character data generation means 15 generates pseudo character data for the character “f” by coordinate conversion represented by the formula shown in FIG. 10B (step S17), and the pseudo character data is It is supplied to the character pattern generation means 16, and the character pattern generation means 16 generates a character pattern (character pattern data) such that the character “f” is displayed in the pattern on the left half of FIG. 20 (step S1)
0).

With the above, the process for the character "f" immediately after the character string "di" is once completed. Next, when the character code of the character "f" after the character string "dif" is input to the character data reading means 11, first, the character data of the character "f" is read from the character data storage means 12 ( In step S1), the character data is stored in the character data temporary storage means 13 (step S2), and it is determined whether or not the replacement information is stored in the replacement processing means 14 (step S3).

The character before this character "f" is also a character "f" having a succeeding list. At this time, since the replacement information is stored in the replacement processing means 14, the character "f" which is the next character is next. Is determined to be a character in the subsequent list stored in the replacement processing means 14 (step S4). Since the character "f" is in the subsequent list of the previous character "f", it is further replaced. It is determined whether the character is determined (step S13).

As is clear from FIG. 4B, the character string "f
Since the replacement character changes depending on what character follows "f", the replacement character is not yet determined at this time. Therefore, the pseudo character data is updated next (step S14). That is, the outline font data O (f) of the character “f” and the coordinate conversion matrix M2 are sent from the character data temporary storage means 13 to the pseudo character data generation means 15, and the pseudo character data generation means 1 is sent.
In FIG. 5, pseudo character data for the character string “ff” is generated together with the pseudo character data for the previous character “f” by the coordinate conversion represented by the formula shown in FIG.

Next, the pseudo character data is supplied to the character pattern generating means 16 and the character pattern generating means 16 is supplied.
In FIG. 11, a character pattern (character pattern data) that displays the character string “ff” in the pattern of FIG. 11B is generated and output to the upper processing device 20 (step S1).
0). With the above, the process for the character string “ff” after the character string “di” is once ended.

In this case, the feed width of the pseudo character data is set to zero so that the data is overwritten when the character string "ff" is replaced with the replacement character or the pseudo replacement character after the replacement is determined as described below. The replacement is made, and the replacement is easily performed after the replacement is determined.

Next, when the character code of the character "e" after the character string "diff" is input to the character data reading means 11, first, the character "e" is read from the character data storage means 12.
Is read (step S1), the character data is stored in the character data temporary storage means 13 (step S2), and it is determined whether or not replacement information is stored in the replacement processing means 14 (step). S3).

The character "f" before the character "e" is a character having a subsequent list. At this time, since the replacement information is stored in the replacement processing means 14, the character "e" is replaced by the replacement processing means. It is determined whether or not the character is in the subsequent list stored in 14 (step S4). Since the character "e" is not in the subsequent list of the character "f", replacement of the character string "ff" is determined next. (Step S5).

Next, it is judged whether or not there is a character code of the replacement character of the character string "ff" in the replacement information stored in the replacement processing means 14 (step S).
6). In this example, the character "f" is displayed as shown in FIG.
This is a case where the character code C (ff) of the replacement character of the character string "ff" exists in the replacement information of.

Therefore, next, the character code C (f
f) is the character data reading means 1 from the replacement processing means 14.
1 is input, the character data of the replacement character of the character string "ff" is read from the character data storage means 12 (step S7), and the character data is replaced with the character data of the character "f". Data temporary storage means 1
3 (step S8).

Next, the replacement information is erased from the replacement processing means 14 (step S9), and thereafter, the character data of the replacement character of the character string "ff" (outline font) is sent from the character data temporary storage means 13 to the character pattern generation means 16. Data) and the character data (outline font data) of the character "e" are sequentially transmitted, and the character pattern generating means 16 replaces the character pattern of the character string "ff" and the character "e" as shown in FIG. The character pattern “” is sequentially generated and the upper processing device 2
It is sequentially output to 0 (step S10). At this time, as described above, the character string “ff” is replaced with the replacement character so that the data is overwritten.

Since the last character "r" of the character string "differ" has no succeeding list and the replacement information is deleted by the replacement processing means 14 as described above, the character code of the character "r" is next. When input to the character data reading means 11, the character data is read from the character data storage means 12 (step S1), and the character data is stored in the character data temporary storage means 13 (step S).
2), and the character pattern generation means 16 sequentially generates and outputs a character pattern (step S10).

In this way, the character string "differ"
Is displayed with its character string "ff" replaced with a single replacement character.

Next, the case where the character code of each character forming the character string "difficult" is sequentially input to the character processing device 10 will be described. Until the character codes of the characters “d”, “i”, “f”, and “f” are sequentially input to the character data reading unit 11, the same as in the case of the character string “differ” described above.

When the character code of the character "i" after the character string "diff" is input to the character data reading means 11, first, the character data of the character "i" is read from the character data storage means 12 ( In step S1, the character data is stored in the character data temporary storage means 13 (step S1).
2) It is determined whether or not replacement information is stored in the replacement processing means 14 (step S3).

At this time, since the replacement information is stored in the replacement processing means 14, it is next judged whether or not the character "i" is a character in the subsequent list stored in the replacement processing means 14 (step S4), since the character "i" is in the subsequent list of the character "f", it is further determined whether the replacement character is determined (step S13).

As is clear from FIG. 4B, the replacement character is determined at this time. Therefore, immediately after the pseudo character data is not updated, the character string "ff
The replacement of "i" is determined (step S5).

Next, it is judged whether or not the replacement information stored in the replacement processing means 14 contains the character code of the replacement character of the character string "ffi" (step S6). In this example, as shown in FIG. 4B, the character code C (ffi) of the replacement character of the character string “ffi” exists in the replacement information of the character “f”.

Therefore, next, the character code C (f
fi) is input from the replacement processing unit 14 to the character data reading unit 11, the character data of the replacement character of the character string “ffi” is read from the character data storage unit 12 (step S7), and the character data is further read. It is replaced with the character data of the character "f" and stored in the character data temporary storage means 13 (step S8).

Next, the replacement information is erased from the replacement processing means 14 (step S9), and thereafter, the character data of the replacement character of the character string "ffi" (outline font) is sent from the character data temporary storage means 13 to the character pattern generation means 16. Data) is transmitted, and the character pattern generation means 16 generates a character pattern of the replacement character as shown in FIG. 6B of the character string “ffi” and outputs it to the upper processing device 20 (step (S10)).

The characters "c", "u", "l" and "t" after the character string "difficult" have no successor list, and the replacement information is erased by the replacement processing means 14 as described above. , Then the letters "c" and "u"
When the character codes "l" and "t" are sequentially input to the character data reading means 11, the character data is read from the character data storage means 12 for each character (step S1), and the character of the character data is read. Data temporary storage means 1
3 (step S2), and the character pattern generation means 16 generates and outputs a character pattern (step S1).
0) is sequentially performed.

In this way, the character string "difficu
"lt" is displayed by replacing the character string "ffi" with a single replacement character.

In the above example, the character strings "ff" and "ffi"
FIG. 5 for each of “ffl”, “fi”, and “fl”
(B) to FIG. 9B, there is a replacement character, but if such a replacement character does not exist, the character string is a pseudo replacement character by coordinate conversion by the coordinate conversion matrix. Is replaced by

For example, when the replacement character of the character string “ff” does not exist and the character code of the character string “differ” is input to the character processing device 10, the character “diff” after the character string “diff” is input. The character code "e" is input to the character data reading means 11, and it is determined that the character code of the replacement character of the character string "ff" does not exist in the replacement information stored in the replacement processing means 14 in step S6. Next, the character data temporary storage means 1
3 sends the outline font data O (f) of the character "f" and the coordinate conversion matrices M1 and M2 to the pseudo character data generation means 15, and the pseudo character data generation means 15 shows them in FIGS. Character data for the pseudo replacement character of the character string "ff" is generated by the coordinate conversion represented by the equation (step S12).

Next, the replacement information is erased from the replacement processing means 14 (step S9), and thereafter the character data of the pseudo replacement character of the character string "ff" is sent from the pseudo character data generation means 15 to the character pattern generation means 16. Then, the character string “ff” is generated in the character pattern generation means 16.
A character pattern for the pseudo replacement character is generated and output to the upper processing device 20 (step S10).

However, when there is no replacement character for a character string consisting of three characters such as the character strings “ffi” and “ffl”, three coordinate conversion matrices for the three characters are prepared and the three coordinates are set. The conversion matrix is designed to coordinate-convert the three-character outline font data so that a character string consisting of three characters is replaced with a pseudo replacement character having a width of one character.

When displaying a character on the display means 25 and printing the character on the paper, for example, a character pattern temporary storage means for display 24 and a character pattern temporary storage means for printing are provided. The character pattern of the replacement character or the pseudo replacement character after the replacement is determined is stored in the character pattern temporary storage means for printing from the character pattern generation means 16, and the character pattern is stored in the printing means from the character pattern temporary storage means for printing. It may be sent out.

According to the above-described example, the character string can be independently replaced by the character processing device 10 of the document creating system, and the character string can be reliably written regardless of the configuration or control information of the upper processing device 20. With the replacement, the same quality character output can be obtained. Also, add the replacement information added to the character font data,
Alternatively, by rewriting, the character string or the replacement character to be replaced can be easily added or changed regardless of the configuration or control information of the higher-level processing device 20.

Further, according to the above-mentioned example, each character constituting the character string to be replaced is sequentially displayed according to the operator's input operation until the replacement character or the pseudo replacement character is displayed after the replacement is determined. ,
The operator can successively confirm his / her input operation on the display screen.

The character data of the replacement character is stored in the character data storage means 12, and instead of being read from this, it is internally generated by the replacement character information such as the character code of the replacement character in the replacement information. You can also Further, when the specific character string is always replaced with the replacement character instead of the pseudo replacement character, the subsequent list itself can be used as the replacement character information.

As the character font data, bitmap font data may be used instead of the outline font data.

The present invention is not limited to the ligature process, but includes a ligature process for combining a plurality of characters to form one character as shown in FIG. 12, and a plurality of character elements such as Hangul characters. The present invention can also be applied to a combination process of forming a single character by combining.

[0070]

As described above, according to the present invention, it is possible to independently perform ligature processing or the like in the character processing device of the document creation system, and thereby, regardless of the configuration or control information of the host processing device. As a result, the ligature process is surely performed, and the character output of the same quality can be obtained, and the target character string or character element string for the ligature process or the replacement character can be easily added or changed.
