However, the manual operation is entirely done manually,
If the master is not skilled enough, it is not always possible to input document information efficiently. Another possible method is to scan the document optically and input it as image data, similar to a facsimile machine. The amount of data is several ten times larger than that of d1 character code data C. Although the input operation is relatively simple, the storage efficiency is not good. Therefore, it seems desirable to use an OCR device to recognize the characters and convert them into codes manually. However, as mentioned above, the kanji recognition function for Japanese characters is a difference value, and although the research and development of multi-directional kanji OCR has been successful, it has not yet reached the level of practical use due to problems with recognition rate, etc. Inari. Furthermore, even if kanji 0Cut is put into practical use, it is impossible to hope for a 100% recognition rate.Objective of the present invention←1. Disadvantages and problems of the conventional method as described above. In order to solve the problem, the aim is to provide an efficient document information input method by utilizing character recognition means and effective human support means3. A human-powered scanning means manually scans the document image, performs student recognition from the document image obtained by the human-powered scanning means, converts and outputs the recognized character image into a corresponding character code, and converts the recognized character image into a corresponding character code. For possible character images, a character recognition means that outputs a specific character code and the character image itself,

FIG. 1 is a block i/ladle showing an example of the structure of the document information input method of the present invention. 1 is an optical scanner that optically scans a document and obtains a character image; 2 is a character recognition device;
tl′Aυ Sentence 1 image from optical scanner 1 is received, character by character is recognized, and the code of the recognized character (for example, J, [S Kanji code) and the unrecognized character 1 (for example, A specific character code (using the JIS Kanji code and repeated 7-nari code and - code) is output to the input editing control device 3, and the code and image of the unrecognized character is sent to the external character registration control device 8. When the manual editing control rack M3 inputs the character code from the character + IM device 2 into the Panzer memory 4-1, it sends it out.
For editing instructions to raise (1) the human-powered characters 21-1° of the human-powered character device η (e.g. pe/touch-type kanji human-powered device) or 1) from the sentence 9 and the human-powered device 7 ('koset V). 1 Mori 6 and -A, - operation go up and store 15 (desired Q') in buffer candy 7 4. Performs editing control for stone b in step 4. The display output control device 5 controls the output of the external storage device (for example, the solo playback disk device) 9-\ for the string of character strings stored in the storage device 7-1.

Normally, the character recognition device 2 does not necessarily have one dot configuration for the internal character pattern for nine character images, so in such a case, the external character pattern The registration control device 8 includes a conversion circuit for converting the degree of the character pattern (the tabs and dots in the y-J1 that make up the character). The character input device 7 allows desired characters to be input manually according to the user's instructions, and is equipped with a function key that allows the display screen to be changed and the characters ml-F column in the buffer memory 4 to be used for @return. are doing.

Next, the operating procedure of the document information manual apparatus of FIG. 1 having the above-described configuration will be explained. When the paper containing the 8 manually-generated documents is loaded onto the optical scanner and scanning begins, an image of the document being scanned is input to the Literary Museum's device 29. The character recognition device 2 sequentially cuts out character parts from a character image and performs character recognition. The code ``g identification'' is stored in the buffer memory 4 via the input editing control device 3 as a character code 1''. If there is a character that cannot be recognized by the character recognition device 2, a specific code is given to that character and stored in the Shibanon memory 4, while at the same time the character registration control device 8 is notified that the character cannot be recognized. The image of the written character and the applied coat are sent as a pair. The external character registration control device 18 registers external characters in the display device ii', 6 after converting the character image to match the order of the internal character pattern handled by the display device 6. Through these steps, the contents of the characters are stored in the back-ame-senri 4. The contents of the buffer memory 4 are displayed on the screen via the display output control device 5 and sent to the C display device 6iC. Recognized characters are displayed in internal character patterns on the display device 6,
As for the characters that could not be recognized, I was impressed that almost the same characters/images were displayed as they were in the scanned image obtained by the character bar/turf that registered the external characters, that is, the optical scan V-kina 1. While looking at the display screen, the user can easily check the character pattern displayed in the external character pattern, and use the character input device 7e4/ψ to input the corresponding character manually. C. The part of the external character pattern can be erased as an internal character pattern. 7. This allows the external character code of the temporarily given unrecognized character stored in the backup memory 4 to be changed to the regular character code. Able to make corrections.

For example, the external character ``Butter'' has an internal character pattern of 24 de.

tx24 On the platform where the king is represented by dots, there are 8 characters of 3 dragon horns / scanned with the resolution before and after the battle) It corresponds to the image of X, and normal documents are sufficiently readable by humans]
If the resolution of the optical scanner 1 is higher than this, there will be no problem.0Also, if the recognized character string (internal pattern) contains some unrecognized characters (external character pattern), the user can Easily reading characters displayed in external character patterns from the surrounding text is iJ ability. In this way, when the information is clean (7), for peace of mind, the contents of the backup memory 4 are transferred to the external storage device 9 via the display/output control device 5 in accordance with the function key instructions of the text input device Jt7. Can be stored.

FIG. 2 is a block diagram showing another example of the structure of the present invention.

The configuration in FIG. 2 uses the microcombi, -ta] 0 as the control device 1, and includes the input editing control device 3, display output control device fi, 5, and external character registration control device in the configuration example in FIG. 8 is replaced with a microcomputer 10, and its operation is the same as the configuration example shown in Fig. 1.
In addition, by providing a communication control device [11], it is possible to input and transmit document information to a remote device.

As described above, the document information human-powered device of the present invention is as follows.
The character recognition function allows document information to be read manually at high speed, and even if recognition performance is insufficient, the effective man-machine interface allows for easy and accurate on-campus information, making it possible to create quick and compact documents. It provides an input method that enables the storage and transmission of information.
We believe that this is a useful method for improving the efficiency of sentence processing.

It should be noted that the configuration example of the present invention described above does not limit the scope of the invention, and it is clear that modifications of the structures etc. can be considered based on this example.
