Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document processing device that can optically read document information written in a manuscript, encode it, and edit it.

[Conventional technology]

Conventionally, in document processing devices that have a character recognition function that can optically read document information via photoelectric conversion means, code it, and edit it, characters read from an image sensor or the like are passed through an internal discrimination routine, A so-called pattern matching method was used to convert the characters into the corresponding code.

[Problem to be Solved by the Invention 1] However, in the conventional example as described above, information on the size and thickness of the characters could not be determined, and the following problems occurred.

■For example, when reading double-width characters, they were converted to completely different characters or were judged to be unrecognizable.

■For example, when reading bold characters, they were converted in the same way as normal characters.

Even though the document processing device has the ability to process the character shape, the recognition routine did not have the information (reference pattern) for determining the size and thickness of the character, so normal code conversion was not possible. There was a problem that it was not done.

The purpose of the present invention is to solve the problem when the size and thickness of characters in a manuscript are different from standard characters, such as double-width or bold [Means for Solving the Problem] an image reading means for optically reading document information and converting it into electrical image data; a determining means for determining at least one of the size and thickness of each character of the image data by pattern matching; The present invention is characterized by comprising a storage means for adding and storing at least one of the size and thickness of the character determined by the determination means as attribute data to the character code of the corresponding character.

[For production]

In the present invention, the size and thickness of each character (image data) read by an image sensor is determined, and the determined size and thickness of the character is recorded as attribute data by adding it to the character code. Characters with different shapes from normal standard characters, such as double-width characters and bold characters, can be converted into codes correctly, and a high conversion rate can be achieved.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Φ1” mortar FIG. 1 shows the basic configuration of an embodiment of the present invention.

In the figure, A is an image reading means for optically reading document information written on a manuscript and converting it into electrical image data in a document processing apparatus having an editing function. B is a determining means for determining at least one of the size and thickness of each character of the image data by pattern matching. Reference numeral C denotes a storage means for storing at least one of the size and thickness of the character determined by the determination means B, added to the character code of the corresponding character as attribute data.

Figure 2 shows the circuit configuration of an embodiment in which the present invention is applied to a document processing device. The document processing device of this embodiment includes a CRT+ (central processing unit) 1 that controls the entire device, and this CPU.
RO that stores the control program as shown in Figure 3 of I.
M (read only memory) 2 and RAM (random access memory) 3 that stores various data and programs
It is composed of. Additionally, there is a CRT (cathode ray tube display device) 4 as a display device for editing documents, an external storage device 5 for storing read and converted data, a keyboard 6 for manually operating various keys, and an image scanner for reading documents as image data. (
An image reading device) 7 is provided.

FIG. 3 is a flowchart showing the control procedure of the apparatus according to the embodiment of the present invention shown in FIG.

Next, the control operation of one embodiment of the present invention will be explained with reference to FIG.

First, manuscript information with written text is read from the image scanner 7 (S1). This read manuscript information is
Although it is written in AM3, it can also be stored in external storage device 5.

When the document information is written in the RAM 3, the control program in the ROM 2 searches for the presence of image data that appears to be characters in the document according to instructions from the keyboard 6 (S2). If image data that appears to be text is not found in the manuscript, it is determined whether all character images have been searched, that is, whether the entire area of the manuscript has been searched (S12), and the process is complete. If so, all processing is completed, and if not completed, the process returns to step S2 described above.

If image data that appears to be characters is found in the document in step S2, the control program starts pattern matching with character data. First, for example, the character “A” is compared with a human character image (S3
), if it is determined that they match, a total of 2 bytes of the character code "A" and the attribute code indicating that it is a normal character are recorded in the RAM 3 as one character's worth of data (S4).

If the two do not match in step S3, the input character image and the double-width character "A" (for example, double-width horizontal character) are compared (S5). If this comparison matches, ゜゛A
A total of 2 bytes, including the character code “” and the attribute code “double-width character,” are recorded as data for one character (S6
).

If the two do not match in step S5, the input character image is compared with the uppercase letter ゛A゜゜ (S7). If the two match in this comparison, an attribute code of ゜゜A゜゜ bold is added to the character code "A" and it is recorded in RAM 3 as one character data (S
8).

If the two do not match in step S7, it is checked whether or not the comparison has been made with all the character tables that the control program has (S9). is stored in RAM3 as an unidentifiable character.
(SIO).

If character image data still remains in the character table in step S9, the next character candidate is set and the process returns to step S3 (Sll). In this embodiment, since the comparison was made with "A", "B" is set next in step Sll.

Note that when steps S4, S6, S8, and SIO are completed, the process advances to step Sl2 to begin searching for the next candidate human-powered character image.

〔Effect of the invention〕

As explained above, according to the present invention, character images retrieved from document information read from an image scanner are compared with more types of character tables, so it is easier to obtain accurate character code data. The effect of realizing a high conversion rate can be obtained.
