Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for producing a document, and more particularly to an apparatus and method for producing a document which can determine and output a long-sound character "-" or a minus character "-".

[0002]

2. Description of the Related Art In recent years, a document creating apparatus has become widespread in which a character input by handwriting is recognized using a character recognition technique to create a sentence containing Chinese characters.

In the character recognition technology of this document creating apparatus, generally, character recognition processing is performed according to a pattern of characters manually input.

However, there is a problem that a character different from the character input by the operator is recognized and output for a character such as a long-sound character "-" or a minus character "-" which is difficult to write.

In view of the above, the present invention provides a document preparation apparatus and a document preparation apparatus for improving the recognition accuracy by judging characters that are difficult to write, such as long-sound characters "-" or minus characters "-", based on the immediately preceding character information. The purpose is to provide a method.

[0006]

DISCLOSURE OF THE INVENTION The document creating apparatus of the present invention includes a character input means for inputting handwritten characters, a character recognizing means for recognizing characters input by the character input means, and a character recognizing means. When recognizing a long-sound character "-" or a minus character "-", a judgment means for judging whether it is a long-sound character "-" or a minus character "-" based on the character information immediately before it and the character judged by this judgment means are output. And a document output device for outputting the document.

When a handwritten character is input and the input character is recognized and the input long-sound character "-" or the minus character "-" is recognized, the long-sound character "-" is read according to the character information immediately before it. It is intended to provide a document creating method characterized by determining whether "" or a minus character "-" and outputting the determined character.

[0008]

[Function] Inputs handwritten characters and recognizes them. It is determined whether the recognized long-character "-" or the negative character "-" of the recognized character is a long-character or a negative character based on the character information immediately before it. The determined character is output.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the document creating apparatus and method of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an outline of the document creating apparatus 10 of the present invention. The document creating device 10 is provided with a character input device 11 such as a stylus pen, and is capable of inputting handwritten characters. This character input device 11
A central control unit 13 having a CPU and the like is connected to the input interface 12 for recognizing and discriminating handwritten characters.
Storage, output, etc. are controlled.

The central control unit 13 includes a character recognition unit 14
And a ROM having a program section, a dictionary section, a storage section, etc.
15 is connected to perform character recognition, judgment, program control, character calling, storage, and the like. A RAM 16 is also connected to the central controller 13 so as to store input characters and various control data, information and the like.

Further, a display control device 19 is connected to the central control device 13 via a display control device 18 having a display dot storage section 17 to output input characters and the like.
It is supposed to be displayed.

2 and the flowcharts of FIGS. 3 and 4 in the case where the long character "-" or the minus character "-" is recognized and displayed on the display device 19 by the document creating device 10 thus configured. An explanation will be given with reference to the handwriting input character example of.

First, as shown in FIG. 3, a stylus pen (not shown) is used to input "F" in the rectangular frame 21 of the character input device 11, "B" in 22 and "-" in 23. . The input "flow ..." Data is sent to the central controller 13 via the input interface 12. In the central controller 13, this "flow ..." data is stored in the ROM 15
To the character recognition device 14 for character recognition for each character (S1).

When the character recognizing device 14 recognizes a character of a long-sound character "-" or a minus character "-" in the input data (S2), one of the characters of the long-sound character "-" or a minus character "-" is recognized. It recognizes whether the character information immediately before the character type, that is, "katakana" is "Hiragana" (S3).

If it is recognized that there is no long-sound character "-" or minus character "-" (S2), character recognition is performed as it is and the result is stored in the RAM 16.

When the character preceding by one character is recognized as "katakana" or "hiragana" (S3), the character is determined to be a long sound character (S4). This judgment result is stored in RAM1
Store in 6.

When the character preceding by one character is recognized as neither "katakana" nor "hiragana" (S3), it is recognized whether the character preceding by one character is other than kanji (S5).

The "flow ..." Data stored in the RAM 16 is sent to the display control device 18 via the central control device 13 and is sent to the display device 19 as dot data. The display device 19 displays the dot data as "flow".

Next, a stylus pen is used to indicate "1" in the rectangular frame 21 of the character input device 11, "+" in 22, 22 in "2", 24 in "-", ..., As shown in FIG. input. The inputted "1 + 2 -..." data is sent to the character recognition device 14 of the ROM 15 via the input interface 12 and the central control device 13 in the same manner as the "flow ..." Data to perform character recognition for each character (S1). ).

When the character recognizing device 14 recognizes a long sound character "-" or a minus character "-" (S2), it recognizes whether the character preceding the character is "katakana" or "hiragana". (S3).

If the character one character before is not "Katakana" or "Hiragana" (S3), it is recognized whether the character one character before is a Kanji character (S5). Based on this recognition, the character is determined to be negative (S6), and the result of this determination is stored in RAM1.
Store in 6.

The "1 + 2 -..." Data stored in the RAM 16 is sent to the display device 19 via the central controller 13 and the display controller 18, and displayed as "1 + 2 -...".

As described above, according to the document creating apparatus of the present invention, even if there is a character in which the long-sound character "-" or the minus character "-" is difficult to recognize, the accuracy is determined by the character type immediately before the character, that is, the character information immediately before. Characters can be well recognized and judged.

[0025]

As described above, the text preparation device of the present invention has a character input means for inputting handwritten characters and the like, a character recognition means for recognizing a character input by this character input means, and this character. Depending on the character information immediately before the character information recognized by the recognition means, a long sound character "-" or a minus character "-"
Since it is provided with a discriminating means for discriminating the character and an output means capable of outputting the character discriminated by the discriminating means, it is possible to accurately recognize and determine the difficult long-sound character "-" or the minus character "-" and output.

Further, a character or the like is input, the input character is recognized, the long sound character "-" or the minus character "-" is discriminated by the character type immediately before the recognized character, and the discriminated character is output. As a result, the input processing of the input character can be performed accurately and easily.

Further, when the character string information or the like is input by handwriting and the information is recognized, the conversion processing is performed by referring to the immediately preceding input character information. The recognition can be accurate.
