Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a computer program input device for inputting character data such as a program into a computer such as an engineering workstation M/.

[Conventional technology]

Figure 5 shows a conventional engineering workstation (
This is a block connection diagram showing a program input device for a program input device (hereinafter abbreviated as EWS). TSPI disk and hard disk, 4 main memory, 5 enlarged central processing unit (hereinafter referred to as C
(referred to as PU), 6 and 7a are respectively a keyboard and a mouse as input devices, and a system bus for 8-channel control and expanded data.

Next, the operation will be explained.

First, when inputting a program into the EWS as a computer, the user compares the handwritten program on the coding paper with the input program displayed on the CRTIK while inputting one character at a time ($) on the keyboard. The nine programs thus input are transferred via the main memory 4 to the floppy disk 2 or hard disk 3, which is an auxiliary storage device.

On the other hand, once the program has been stored on the floppy disk 2 through the above input procedure, there is no need to input it again (using the keyboard 6), and the program stored on the floppy disk 2 can be used by any EW that has this floppy disk 2.
Free input/output is possible between S and other EWSs.

[Problem that the invention seeks to solve]

Since the program input device in the conventional EWS is configured as described above, it is necessary to repeat the same operation (such as comparing the same characters but with different shapes on the Co-op Ink paper and the keyboard 6), which reduces the possibility of punching errors. In addition to increasing the probability, key bunching time takes up a high proportion of the EWS usage time, which not only reduces the efficiency of EWS usage, but also causes unnecessary fatigue to the eyes and fingers. Ta.

In general-purpose computers, optical character reading devices (hereinafter referred to as OCR5) are also available, but they have many limitations on usable characters, sizes, fonts, etc., and have a high rate of misreading. There was a problem that it was difficult.

This invention was made to solve the above-mentioned problems, and it eliminates the need for sequential input using a keyboard, etc.
The purpose of the present invention is to obtain a computer program input device that can input a program written by hand on a coding sheet as it is.

[Means for solving problems]

A computer program input device according to the present invention includes:
An image of a handwritten program is read by an image input means, which is an input device, and this image can be compared with a reference image previously stored in a template memory, and by matching these images, the central processing The device is configured to read the contents of the program that is input into the device and convert it into a corresponding character code.

[For production]

The image input device according to the present invention reads the program on the coding paper all at once as an image using a reading device such as a facsimile, outputs a reference image as a tape rate which is registered separately from the template memory, and outputs a standard image as a tape rate which is registered separately from the template memory. After performing pattern matching on these two images, they are converted into corresponding character codes, and the software program 7-eye At-
It acts like 4.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 9 denotes an image input device, such as a facsimile, as an input device for reading characters and drawings.

Reference numeral 10 denotes a tape plate memory in which all reference image data used as a template during pattern matching is stored for each individual (font). Depending on the configuration, the template memory 10 may also be used as the floppy disk 2 or the six-dimensional disk 3, and only the necessary portions may be read into the main memory 4.

Note that other blocks that are the same as those shown in FIG. 2 are designated by the same reference numerals, and redundant explanation thereof will be omitted.

Next, the operation will be explained. First, the computer E
When inputting a program to the WS, the characters (including numbers) in the program are input using the image input device i9.
is read into the main memory 4 as an image. On the other hand, the same handwriting as the program input from the template memory 10 is selected, and this is also read onto the main memory 4 as a reference image.

Then, the CPU 5 performs pattern matching on each of these images character by character to decipher the characters on the program and convert them into corresponding character codes. Finally, the source program file is converted into a character code and stored in the floppy disk 2 or hard disk 3 as an auxiliary storage device.

FIG. 2 is a flow diagram showing the processing status from reading the image to outputting the character code. When the program on the coding paper is input as an image to the image input device 9 (step IST), the CPU 5 Now, compare this image with the reference image from the template memory 10 to determine whether the input image corresponds to the numbers Iol, 1gm or the letter "A"#
Steps 2ST, 3ST, 4ST) to decipher whether it corresponds to "Z" or a special character. Steps 5ST, 6ST, 7ST) ,
Output this as a character code (Step 8ST),
After completing all character code processing, the data is stored on a floppy disk 2 or the like (step 9ST).

FIG. 3 is an explanatory diagram showing an outline of the pattern matching process, which is carried out according to the flowchart shown in FIG. 4. First, for example, for the character rAJ, the exclusive OR of each corresponding dot of the input image read into the image input device 9 and the reference image is calculated (step 1
1ST). As a result of step 7, only the portions that do not match each other appear.The image input means determines whether or not the match rate exceeds a specified value depending on the degree of the portions that do not match (step 12ST). If the matching rate does not exceed the specified value, it is then determined in step 13S whether pattern matching has been completed for all images.
T), if the process has not been completed, the process from step 11ST is repeated again. On the other hand, step 12ST
If it is determined that the matching rate exceeds the specified value, the predetermined character code used as the criterion for the determination is output from the template memory 10, and the process is terminated (step 14ST). The specified value used here is separately determined as a parameter setting value, for example, about 90 to 95%.

Furthermore, the above-mentioned matching rate is the ratio of the total number of dots (white portions) in matching portions to all dots in image I.

In this way, when interpreting input characters, characters of the same size and handwriting are used as templates, so OC
There is no need to use a standard font such as R, and the fonts used on a daily basis can be used as they are.It is expected that the misreading rate will be significantly lower than with OCR.

In addition, although the case of EWS was explained in the said Example, it may be a personal computer, a minicomputer, etc., and will produce the same effect as the said Example. In addition, the image input device 9 is a FAX
A device capable of inputting and outputting image data other than the above may be used, and the same effects as in the above AD embodiment can be obtained.

Although the explanation has been given using a program as an example of input data, if kanji are registered in the template memory 10, the word processor can also process sentences written in ordinary Japanese.

〔Effect of the invention〕

As described above, according to the present invention, the image of a handwritten program is removed by the image input means, this image is compared with the reference image stored in the template memory, and these images are matched. Since the central processing unit is configured to read the contents of the program and convert it into the corresponding character code, it is possible to input the program exactly as it is written on the coding paper and with high precision. The time required for punching using a keyboard can be reduced, punching errors can be prevented, and program input work can be made more efficient.
