Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is, for example, input to a Japanese word processor which can be applied to a DTP system.
The present invention relates to a document processing apparatus provided with a character reading unit that is used for input to a personal computer such as input to an optical file system or data input for card creation.

2. Description of the Related Art Conventionally, OCR (Optical Charac
A document processing apparatus that optically reads document data of a document by a ter reader) and performs various control processes on the document data is configured to process the data by the following process.

That is, first, a character original is scanned by the OCR to store a bit image, and the bit image is divided into character units to form a rectangular shape so as to pick up the scattering state and habit of the bit image. As a result, the matching dictionary is used to recognize the character as a character code. Then, the above character code is converted into transmission data, and this is transmitted to the document processing unit, so that the document processing unit performs various control processes on the document data.

[0004]

However, in the above-described conventional document processing apparatus, since the data read by the OCR is only the character code, the transmission data sent to the document processing unit includes characters. The number of points and typeface data are not included. Therefore, after receiving the data in the document processing unit, the user has to use the document editing function to re-create the document in accordance with the character original such as the number of character points and the typeface.

[0005]

The document processing apparatus of the present invention takes the following means in order to solve the above problems.

That is, the character reading means for reading each character of the manuscript coded and reading the number of points for each character and the typeface type as each data and the number of points for each character read by the character reading means. The point number recognition means for recognizing, the font type recognition means for recognizing the font type for each character read by the character reading means, and the character code for which the point number and the font type are recognized by each of the above recognition means Document storage means for storing as document data is provided.

[0007]

According to the above construction, the character reading means reads each character code of the document and also reads each data of the number of points and the type of font for each character. Then, the point number recognizing means and the typeface type recognizing means recognize the respective data of the number of points and the typeface type read by the character reading means, and store them as document data in the document storing means. As a result, since the character code, the number of points, and the typeface type corresponding to each character of the original can be stored as each data, for example, when printing out the above document data, the number of points and typeface type can be changed. It is possible to improve the operability by omitting the setting of each condition.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The following will describe one embodiment of the present invention with reference to FIGS.

The document processing apparatus according to the present embodiment includes a character reading unit (character reading unit) for reading each character (document data) of an original by coding, and various document data read by the character reading unit. And a document processing unit for performing the control process of.

As shown in FIG. 1, the character reading section first optically reads each character of a document as a bit image by an OCR (Optical Character Reader) (not shown) (S1). The OCR reads the number of points and the type of font for each character as data when the character code as a bit image is read. Then, in order to perform the matching process on the bit image, a rectangular range is specified so that the character image is established based on the scattered state of the bit image and the bit image is divided into minimum units (S2).

Next, the features of the bit image and the habits divided into the rectangular shape as described above are collated with the matching dictionary. As a result, the character code, the number of points, the type of font, etc. of the character having a high degree of similarity can be obtained. If the matching is performed alone, it may be meaningless as a word, so the recognition rate is increased by referring to the recognition results of the preceding and following characters and correcting and strengthening the characteristic information. In addition, a plurality of character codes are output as a countermeasure for erroneous recognition, and if an independent word is formed in the candidate character list, a process of bringing that character code to the first candidate. Is performed (S3).

Next, after the above matching processing, in order to unify the number of points in each independent word and the typeface,
Adjusting the number of points (S4) and adjusting the type of font (S
Perform 5). In addition, the adjustment of the number of points is performed by aligning with the largest number of points in the independent word.
The adjustment of the typeface is made by the majority vote in the independent word or by aligning with the typeface first appeared.

Then, the point number, typeface type, character code, etc. obtained as a result of recognition as described above are transmitted as transmission data to a document processing section which will be described later (S6), and in the character reading section as described above. The processing process is terminated.

The above transmission data is, as shown in FIG.
For example, in the document "The capital of Japan is Tokyo,""The capital of Japan" is a textbook with 7.5 points, "Tokyo" is a Gothic font with 10.5 points, and "is" is a textbook with 8 points. In the case of the body, the transmission format is that transmitted as the format shown in FIG. The format shown in FIG. 3 is a tentative exemplary format in which the number of characters, candidate character code, checksum, etc. are omitted.

On the other hand, the document processing section, as shown in FIG. 4, has a reception buffer 1 for storing the transmission data from the character reading section as reception data, and the number of points for recognizing the number of points for each character in the reception data. An information table (point number recognition means) 2, a typeface type information table (typeface type recognition means) 3 for recognizing a typeface type for each character in the received data, and each of the information tables 2 and 3 identified above. A document buffer (document storage means) 4 for storing character data as document data is provided.

The data processing process in the document processing unit will be described below.

First, in S10, the data transmitted from the character reading unit is received and stored in the reception buffer 1 as reception data.

Then, for the character code of the received data, a candidate character selection process is performed (S11).
For example, even when the character "day" is read by the OCR, it is not always recognized as the character "day". Therefore, several candidate character codes are tied together as the character code of the received data. For example, in the case of "day", such as "white", "mortar", and "eye",
The user selects an appropriate character code from the candidates on the screen or the like and inputs it to the document buffer 4.

Regarding the point number data among the received data, it is searched whether or not the point number data fetched from the reception buffer 1 is in the point number information table 2 (S12). If there is no point number data in the point number information table 2 in the search of S12, the closest point number is selected. For example,
When five types of point numbers of 6.5 points, 8 points, 9 points, 10 points, and 12 points are registered in the point number information table 2, the data of the point number retrieved from the reception buffer 1 is 7. If 5 points, the closest 8 points will be processed.

Then, from the input setting state of the cursor position in the document buffer 4, the number of points currently input is known from the document buffer 4, and the number of points obtained by the point number replacement process is collated, If they are the same, the processing to the document buffer 4 is exempted. On the other hand, if the points are different, the input setting state of the document buffer 4 is set to the points (S13). In addition, this setting is
It is valid until the next number of points or the last data of the received data is processed, but for subsequent processing, it affects the number of points after the cursor position before receiving, so the original number of points is automatically set. To return to normal.

For the typeface data among the received data, it is searched whether or not the typeface data retrieved from the reception buffer 1 exists in the typeface information table 3 (S14). If the data of the typeface type is not found in the typeface type information table 3 in the search of S14, the Mincho typeface which is the basic typeface type of the document processing apparatus is selected. For example, in the typeface type information table 3, Mincho typeface, Gothic typeface, regular typeface, line typeface,
When five types of typefaces, ie, round Gothic typeface, are registered, if the data of the typeface type taken out from the reception buffer 1 is a text typeface, the process is performed as the basic typeface type Mincho typeface.

Then, from the input setting state of the cursor position in the document buffer 4, it is known from the document buffer 4 what type of font is currently being input, and it is collated with the type of font obtained by the font type replacement process. If they are the same, the processing to the document buffer 4 is exempted. On the other hand, if the typeface is different,
The input setting state of the document buffer 4 is set to the typeface type (S15). Note that this setting is valid until the next typeface type or the last data of the received data is processed, but since the settings affect the typeface type after the cursor before receiving, It automatically returns to the typeface type.

As described above, the document processing apparatus according to the present embodiment encodes and reads each character (document data) of the document, and also reads the point number and the typeface type of each character as each data. And a document processing unit that stores the transmission data from the character reading unit as reception data and performs various control processes on the reception data. Further, the document processing unit described above includes a point number information table 2 for recognizing the number of points for each character in the received data, a typeface information table 3 for recognizing a typeface for each character in the received data, and each of the above. The document buffer 4 stores each character data recognized in the information tables 2.3.

Therefore, in addition to the character code of each character forming the document data, the number of points and the typeface type for each character can be stored as data in the document buffer 4 of the document processing unit. Therefore, when the document processing apparatus is connected to a printer to print the document data, it is possible to automatically print out with the number of points and the typeface type according to the document data of the document.

[0025]

As described above, the document processing apparatus of the present invention encodes and reads each character of the original document, and reads the point number and typeface type of each character as each data, and character reading means. With the point number recognition means for recognizing the number of points for each character read by the reading means, the typeface type recognition means for recognizing the typeface type for each character read by the character reading means, and each of the above recognition means The document storage means stores each character code in which the number of points and the typeface type are recognized as document data.

Thus, in addition to the character code, the character size (the number of points) and the type of font can be recognized and stored as document data in the document storage means. Therefore, in the case where a printer is connected to the document processing apparatus to print the document data, it is possible to automatically print out with the number of points and the typeface type according to the document data of the original, and It is possible to provide a convenient document processing device with improved operability.
