Abstract

PURPOSE:To handle different forms and also to recognize whether or not the form line numbers are recognized correctly by an OCR section by transferring a picture signal representing the line number corresponding to an ID number from a picture processing section plus a prescribed line number to the OCR section. CONSTITUTION:An OCR facsimile device 1 receives, demodulates, and decodes a facsimile signal transmitted from a facsimile device 2 and converts the signal into a picture signal as to a form. This picture signal is fetched to a picture processing section 12 and stored temporarily and then transferred to the OCR section 13 in the unit of one line. The picture processing section 12 is provided with a pattern generator generating additional information and generates a picture signal of pattern for one line of the forms (a line timing mark). The OCR section 13 recognizes the forms specified number of lines and types of characters to be recognized by the ID number transmitted together with the head line timing mark and outputs a data transfer request signal based thereupon.

Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to an OCR having a facsimile unit that processes a 7-axis signal transmitted by facsimile, and an OCR unit that recognizes an image signal sent from the facsimile unit.
The present invention relates to a data management method in a facsimile machine.

[Technical weight of the invention]

Conventionally, OCR facsimile machines are designed to handle only forms of a specified size, and page information generated by a pattern generator is added to, for example, the bottom edge of the form image as a result of facsimile transmission. This page information was used to manage the page.

[Problems with weight technology]

However, general forms have different sizes,
Furthermore, the number of lines to be recognized differs even between forms of the same size. Therefore, conventional OCR facsimile machines are inconvenient because they can only handle forms of the same size, and they also have the disadvantage that it is impossible to know whether the OCR section has correctly recognized the number of digits in the form.

[Purpose of the invention]

The present invention was made in view of the above-mentioned drawbacks, and its purpose is to be able to handle forms of different sizes, and to know whether or not the number of digits of the form has been correctly recognized by the OCR section. An object of the present invention is to provide a data management method in an OCR facsimile device that can be used in an OCR facsimile machine.

[Summary of the invention]

Therefore, in the present invention, the OCR facsimile device is provided with an image processing section equipped with a pattern generator, and the image signal from the image processing section is the number of lines corresponding to the ID number recognized by the OCR section plus a predetermined number of lines (from the facsimile section). Both the output and the pattern generated by the pattern generator are transferred to the OCR section.

[Embodiments of the invention]

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an OCR facsimile device 1 employing the method of the present invention and a facsimile device 2 on the sending side. The OCR facsimile device 1 is a facsimile machine M.
The facsimile unit 11 receives a facsimile IJ signal sent by facsimile from 2, demodulates and decodes it, and converts it into an image signal for a form. The image signal output from the facsimile section 11 is taken into the image processing section 12 and transferred to the OCR section 13 in units of temporarily stored temporary lines. Further, the image processing section 12 includes a pattern generator, and is configured to generate a necessary predetermined pattern. The image signal sent from the image processing unit 12 is OCR
It is taken into the unit 13, recognized and output (or stock)
be done.

A document transmitted to such an OCR facsimile device 1 is designed as shown in FIG. 2, for example. In other words, black start marks 101 are placed on the n1th to n2th bits and the n3th to nth bits from the left end, from the tip P to the Q2th line of the first block 100. is printed, and a portion of m pit width from the n1th bit from the left end below a predetermined line from the tip P has a length of h pits, indicating that there is an area to be recognized on the right side. row timing mark 10
2 is printed, and similar row timing marks 102 are printed at predetermined bit intervals thereafter. Also, 1
Reference numeral 03 denotes an ID number area for distinguishing the type of form (particularly indicating character rows and lines), and 104 represents a character recognition area printed on the form in a form determined by the ID number.

In this way, the form 100 is input to the facsimile machine 2, converted into a facsimile signal, and then transmitted to the OCR facsimile machine 1.
The facsimile section 11 converts the signals into both signals, and sends them to the image processing section 12. Here, the image processing section 12 is as shown in FIG. That is, the main till 1 part 21
A facsimile section interface 23, an image information memory section 24, an additional information generation means 5, an OCR section IFFIN interface 26 and a production section 27 are connected to a control bus 22 extending from the image signal bus path. A facsimile section interface B, an image information memory section 24, an additional information generating means 25, and an OCR section IFFIN interface 26 are connected.

The main control section 21 controls each section via the bus 22, and
Accepts commands and data input from the operation unit. Further, the additional information generating means 5 is a pattern generator, and generates an image signal (additional information) as shown in FIG. 4, for example. In other words, this image signal is a pattern for one line of the form, and includes the line timing mark 102 and the pattern r-
Contains X-aromatic END-3+%J. Furthermore, a program according to a flowchart as shown in FIG. 5 is stored in the main control section 21, and the main control section 21 executes the program.

The operation will be explained below according to the flowchart.

First, in step 201, the main control section 21 activates the facsimile section interface B and the image information memory section 24, and causes the image information memory section 24 to store the image signal output from the facsimile section 11. Next, step 202
, the main control section 21 inquires of the facsimile section 11 via the facsimile section interface n whether a predetermined amount of image signals have been transferred. Therefore, when a signal indicating that a predetermined amount of image signals has been transferred is sent, the result is YES and the process proceeds to step 203, otherwise step 202 is repeated.

In step 203, the main control section 21 instructs the processor in the image information memory section 24 to detect a start mark. Then, the processor in the image information memory section will
The lines where the start mark 10X as shown in FIG. 2 is present (from the It1st line to the υ2nd line) are main scanned, and the start mark 101 is detected depending on whether or not a predetermined black bit is present.

Therefore, in step 204, the main control section 21 inquires of the image information memory section 24 whether or not a start mark has been detected. At this time, if there is a response that the start mark has been detected, the response is YES, and if there is a response that the p1 start mark is not detected, the process branches to NO, resulting in an error.

Next, the main 1blu section 21 inquires of the image information memory section 24 whether image signals for one page of the form have been stored.

Then, when there is input for one page, the process advances to step 206. In step 206, the main control section 2-2 instructs the image information memory section to detect the line timing mark, and the processor in the image information memory section detects the line timing mark by scanning the black bit at a predetermined position. To detect. In step 207, the position information of the row timing mark, that is, the information on which line the row timing mark shown in FIG. 2 is located is input.

Furthermore, in step 208, the image information memory section 2.1
Then, the OCR unit IFFINTAFACE 26 sends a line transfer command. In step 209, the image signal for each line is transferred from the image information memory unit 24 to the OCR unit interface unit.

Next, the main control unit 2X proceeds to step 210 and determines whether or not the transfer of the form specification line has been completed. In this step 210, the main control unit 21 determines whether the transfer of the specified line of the form has been completed, based on whether the OCR unit 13 has issued a data transfer request signal to the OCR unit IFFINTAFACE 26 or not. The OCR unit 13 prints the first line timing mark 102,! : ID sent together
Based on the ID number in the number area 103, the specified number of lines in the form, the type of characters to be recognized, etc. are known, and based on this, a data transfer request signal is output.In this embodiment, the number of lines determined by the recognized ID number plus Outputs a data transfer request signal once. Note that the image processing section 12 only knows that the specified number of lines has been reached because this data transfer request signal is no longer output, but is not informed of how the OCR section 13 recognized the ID number.

Now, if the answer is YES in step 210, the process ends.
If a data transfer request signal is subsequently output,
If the answer is NO, the process proceeds to step 211, and the main control unit 21
The image information memory unit 24 is inquired as to whether there are any lines remaining to be transferred. Therefore, if there are still rows to be transferred, the answer is YES, and steps 209 to 211
repeat. If there is no row to be transferred, the main control unit 21 proceeds to step 212, outputs an additional information generation instruction to the additional information generation means 25, and in step 213, the additional information generation means 5 (a) One line of additional information is transferred via the C and R section interface 26. After the transfer is completed, the process returns to step 210, and from then on the process continues based on the flowchart.Finally, the OCR section 13 no longer outputs the data transfer request signal, and the process branches to YES in step 210, ending the process.

Since the image processing section 12 and OCR section 13 operate in this way, the number of lines of the image signal transferred to the OCR section 13 is always
The number of lines recognized by the OCR unit 13 based on the ID number is plus one line. Therefore, the recognition result as shown in FIG. 6 is obtained. First, FIG. 6A shows a case where the recognition result based on the ID number is correct and there are 5 lines, and a total of 6 lines have been transferred. in this case,
Since the recognition of ID number area 103 is correct, there is one line of additional information. Next, FIG. 6B shows a case where 5 lines were recognized based on the ID number, but there were actually only 4 lines. In this case, since there are two lines of additional information, this may be due to, for example, one line of image signals being lost during facsimile transmission, or an erroneous recognition of the ID number. Further, FIG. 6C shows a case in which three lines are recognized based on the ID number and four lines in total are transferred. In this case, as can be seen from the fact that no additional information is attached, it seems that the ID number is misrecognized.

For example, such recognition results can be outputted from an OCR facsimile machine and judged by an operator, or the OCR unit itself can store data and information to determine whether additional information has been added. It is possible to determine whether recognition has occurred or not, which is convenient for data management.

〔Effect of the invention〕

As explained above, according to the present invention, an image (No. 7) transmitted by facsimile can be
Since the data is transferred and recognized by the data transfer registration signal from the R section, the problem of being able to handle only the same form as in the past is eliminated. Furthermore, based on the number of lines in the IH report, it is possible to judge whether the recognition result is correct (correct or incorrect ID number recognition and correct or incorrect number of recognized lines) by an operator or by a resource. Moreover, since the additional information is not transmitted by facsimile but is generated in the image processing unit, it has less noise and is convenient for recognition by the OCR unit, making it ideal as a signal used for management. .
