Abstract

PURPOSE:To synthesize and accumulate an obtained mark and picture information, to reduce an accumulated information quantity, and effectively use a storage part by providing a device, which extracts a mark-expressible information area from document information and obtains the corresponding mark, and a device which obtains an inexpressible area. CONSTITUTION:When accumulating the document being accumulated in an original, the document is converted into picture information 101 expressed in a bit image by an original reader part 1. Next, a character is recognized by a character recognizing part, the document information which has successed in recognizing the character is converted into a character code 104, and the document information which has not successed in recognizing the character is outputted as the picture information, compression-processed by an encoder part 3, the document information separated into encoding picture information 103 is information-synthesized 4, and accumulated 5 as the synthetic information. When the cumulative information is fetched, cumulative information 106 is separated by a character code 109 and encoding picture information 107 by an information separating part 6, encoded picture information 107 is decoded 7, and outputted as the picture information.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a document storage device, and more particularly to a document storage device that stores documents written on manuscripts.

BACKGROUND OF THE INVENTION Conventionally, document storage devices of this type have been a sideways process in which all document information is multiplied by N as image information.

Problems to be Solved by the Invention The above-mentioned text storage device processes all document information as image width information, so it has the drawback of storing a large amount of information and requiring a large-capacity storage unit.

The present invention has been made in order to overcome the above-mentioned drawbacks inherent in the conventional technology, and therefore, an object of the present invention is to make it possible to efficiently use a storage device by reducing the amount of information stored. The object of the present invention is to provide a new document storage device with the following features.

Means for Solving the Problems In order to achieve the above object, the text storage device according to the present invention includes a first means for extracting an information region that can be expressed symbolically from document information and obtaining a symbol corresponding to the region; a second means for obtaining as image information a clear information area that cannot be represented symbolically in the document information; and a means for synthesizing and storing the symbols and image information obtained by these first and second means; Prepared and configured.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

Referring to FIG. 1, when accumulating sentence buds written on a manuscript, the document is first converted into an image expressed as a bit image (ffl information 101) by the manuscript reading section.

Next, characters are recognized by character recognition processing, and document information whose characters have been successfully recognized is converted to character code 104, and documents whose characters cannot be recognized +f! The image information is outputted as image information 11]2 and compressed by the encoder 3 to obtain code fhi image information 11]3. The document information thus separated into the character code 104 and the appetizer number information 11 ] 3 is synthesized by the information synthesis section 4 and stored in the storage section 5 as finished information 105 .

Information section C') is used to retrieve the stored text.
The accumulated information 11) 6 is divided into character code 11) 9 and encoded image information 107, and the code f image information 107 is decoded into a bit image by the decoding section 7 and output as image (, T1 information 108. The character code 109 and image information 108 thus obtained are output by the display control section 8 to the CRT 9 and printer 10 as a CRT signal 110 and print signal 111.

FIG. 2 is a flowchart showing an example of the processing outline of the character recognition unit 2 in FIG. 1.

Referring to FIG. 2, when the process starts, first, a process 82 is performed to cut out three characters from the image information of the document.

If the characters cannot be cut out, the process advances to S7, and the information area currently being processed is imported as image information.
If the character has been successfully extracted, the process proceeds to S4, where the feature points of the character are calculated, and the feature points and the dictionary search process S5 are performed.
to determine whether the corresponding character exists in the dictionary. If there is no corresponding character, the information area currently being processed is taken in as image information in S7, and if there is a corresponding character, the character code of the corresponding character is obtained.

FIG. 3 is a diagram showing an example of the processing result of the information synthesis section 4 in FIG. 1.

In FIG. 3, character code D3 and encoded image information D6
5r The character code header D1, the character code attribute D2, and the image information D4.
Wataru (Elephant information attribute 531 size addition 1-).

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, there is provided a first means for extracting an information area that can be expressed symbolically from textual information and obtaining a symbol corresponding to the information area; By having a second means for obtaining information and a means for synthesizing and storing the symbols and image information obtained by these first and second means, the amount of information to be stored is reduced and the storage unit can be used more efficiently. It can be used effectively.
