Abstract

PURPOSE:To effectively use a space of paper and shorten the communication time for mail delivery by providing a means which recognizes a delivery control mark in a delivery control mark extraction area surrounded between a start point and an end point. CONSTITUTION:A delivery control mark recognizing part 400 takes scanning line numbers from the scanning line number corresponding to the start point of a start mark transferred from a start mark extracting part 200 from that corresponding to the end point of an end mark transferred from an end mark extracting part 300 as the mark recognition object by the command of a control part 900. The delivery control mark where delivery control parameters such as destination designation and time designation are described is recognized on a basis of the processing result of a sampling processing part 500 and mark prescribing information of a mark prescribing information control part 700. Thus, the positional variance of the delivery control mark due to the difference of facsimile equipments is corrected, and a mark describing format is not fixed to add and delete easily the delivery control mark.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mail destination recognition method in a facsimile mail system, etc., and particularly to a mail destination recognition method suitable for reducing communication time and communication cost during mail delivery. It is something.

[Conventional technology]

In facsimile mail systems and the like, a method is known in which mail is delivered by recognizing and processing marks that describe destination information, delivery control information, and the like.

In this mark recognition process, mark position information is important. However, in the past, the position of the mark often fluctuated due to differences in facsimile machines and the inclination and misalignment of paper during input.

FIG. 2 shows an example of such a change in the position of the mark.

FIG. 2(a) is an example of an input form 1 with a mark 2 written on it, and FIG. 2(bl) is an example of an output form 1 with a calling telephone number and date added to the top edge of the input form 1 by a facsimile machine.
0, and the mark position is moved by a deviation width of 200 in the vertical direction from the expected position. Similarly, in Figure 2 (
b2) is an example of movement in the left-right direction by a deviation width of 30.

Furthermore, when mail is delivered using a facsimile device or the like, there are many different combinations of delivery control parameters such as destination designation, time designation, etc. depending on the type of mail, so the amount of marks corresponding to the parameters varies. However, in the above method, all the parameters are written on the same page regardless of the type of mail, and the mark extraction area is fixed. Therefore, this type of method is effective when the amount of writing is large, but when it is small, the range of unnecessary mark extraction areas on the paper increases. for example,
When using a small amount of delivery control parameters, the mark and email text corresponding to the parameters can be expressed on a single sheet of paper, but all possible parameters, including parameters that are not needed for the time being, should be written on the first sheet. It consists of two pages, with the mark indicating the message being written on and the mail text written on the second page, and when sending the mail, an extra communication time is required on one page.

[Invention tries to solve +7t7 X! 1 point] In the conventional method described above, mark recognition processing was difficult because the mark position fluctuated due to differences in facsimile machines. In addition, since the mark extraction area is fixed regardless of the device in facsimiles, etc., if the amount of marks written in relation to delivery control parameters is small, the range of unnecessary mark extraction areas on the paper will increase, resulting in unnecessary mark extraction. There was a problem in that it required a lot of processing time. Furthermore, due to the increase in the range of the unnecessary mark extraction area, there is a problem that the paper space cannot be used effectively, and that communication time during mail delivery becomes longer and communication costs become higher.

SUMMARY OF THE INVENTION An object of the present invention is to provide a mail destination recognition method that can solve these conventional problems, make effective use of paper space, and reduce communication time and communication costs during mail delivery.

[Means for solving problems]

In order to solve the above problems, the present invention provides a mail destination recognition method that recognizes a delivery control mark including the destination from the compressed image signal of the mail input from a facsimile, and delivers the mail from the compressed image signal. sampling processing means for sampling and expanding a scanning line; means for determining a start mark based on the sampling processing result and extracting a starting point of the delivery control mark extraction area; and based on the extraction result of the starting point. means for determining an end mark from the processing target area determined by the process and extracting the end point of the delivery control mark extraction area; and means for extracting the delivery control mark extraction area from the delivery control mark extraction area surrounded by the start point and the end point. By using the start mark and end mark, the position of the delivery control mark in the vertical and horizontal directions with respect to the compressed image signal is corrected, and the delivery control mark that changes is corrected. The feature is that it extracts the area.

[Effect]

When the delivery control mark is recognized for mail input from a facsimile machine and the mail is delivered, the start mark and end mark are used to mark the delivery control mark due to differences in facsimile machines and the skew and misalignment of the paper during input. In addition to correcting positional fluctuations, delivery control marks can be added or deleted without fixing the mark description format.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

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

In FIG. 1, 80 is an input/output terminal, 100 is an input/output interface section, 200 is a start mark extraction section, 300 is an end mark extraction section, 400 is a mark recognition section for delivery control,
500 is a sampling processing unit, 600 is a storage unit, 610
is an image memory, 620 is a scanning line map memory, 70
0 is the mark regulation information management section, 800 is the delivery processing section, 90
0 is a control unit.

In order to operate this, the input/output interface section 100 receives the compressed image signal of the facsimile mail transferred from the J terminal 80 in response to a command from the rrIJ control section 900, and sends the compressed image signal to the image memory 610 of the storage section 600. At the same time, a correspondence table between each scanning line number of the compressed image signal and the corresponding storage address on the image memory 610 is stored in the scanning line map memory 620. After storage is complete,
The input/output J interface section 100 notifies the start mark extraction section 200 that the compressed image signal has been received. In response to a command from the control unit 900, the start mark extraction unit 200 requests the mark regulation information management unit 700, which stores parameters and mark size widths, etc., to obtain regulation information regarding the start mark, and obtains the regulation information. A processing request is made to the sampling processing unit 500 based on the specified information.

FIG. 3 is a diagram showing an example of defining the extraction range of start marks and end marks according to this embodiment.

The start mark 51 is an X from the upper end 50 of the image signal.

It is extracted from the range of positions from position to X according to the following process. Regulation information XI and X are based on paper deviation width of 20? , to be determined. The sampling processing unit 500 samples and expands the compressed image signal for each book in 11 stripes during scanning 914 in the range from the position Xl to the position x2 in accordance with a processing request from the start mark extraction unit 200. When sampling, the scanning line map memory 6 of the storage unit 60.0 is used.
The correspondence table stored in 20 is referred to. After the sampling process is completed, the start mark extraction section 200 uses the processing result of the sampling processing section 500 to extract the start mark 5.
1 exists or not. The criterion for determining the presence or absence of a mark is included in the information acquired from the mark regulation information management section 700.

FIG. 4 is a diagram showing regulation information for determining the presence of a start mark and an end mark according to this embodiment.

A series of data of the left vertical mark width B1, the inter-mark margin width W, and the right vertical mark width B2 match the expansion result of the scanning line 40 sampled for each book in scan t9,
If the number of matching scanning lines 40 is greater than or equal to a certain set value and less than or equal to L/ within the vertical width of the vertical mark, it is determined that the start mark 51 or the end mark 55 exists. If the start mark extraction unit 200 cannot determine the existence of the start mark 51, it notifies the delivery processing unit 800 of this fact.

In this case, the delivery processing section 800 outputs a message that mail cannot be accepted to the input side via the input/output ink face section 100. On the other hand, if the existence of the start mark 51 can be determined, as shown in FIG.
The scanning line number corresponding to 8 is transferred to the end mark extraction section 300 and the delivery control mark recognition section 400. After the transfer is complete,
In response to a command from the control unit 900, the end mark extraction unit 300 requests the mark regulation information management unit 700 to obtain regulation information regarding the end mark, and as shown in FIG. The sampling processing unit 50 issues a processing request for sampling in the range of positions from ~Y2.
Notify 0. The regulation information Y and Y determine the variation range of the delivery control mark extraction area. After the notification, the sampling processing unit 500 samples and expands the compressed image signal for each book at scanning line intervals in the range from the Yl position to the Y positions. After the sampling process is completed, the end mark extraction unit 300 uses the processing result of the sampling processing unit 500 to determine whether or not the end mark 55 exists in the range from the starting point 58 of the start mark to the position Z. Perform discrimination processing. The regulation information Z and Z2 indicate the relative positions of the start mark and end mark in the left-right direction and the range of variation thereof. The method for identifying the mark is the same as that for the start mark 51, as shown in FIG. End mark extraction part 3
00, if the existence of the end mark 55 cannot be determined,
The delivery processing unit 800 is notified of this fact.

In this case, the delivery processing section 800 outputs a message that mail cannot be accepted to the input side via the input/output interface section 1oO. On the other hand, if the existence of the end mark 55 can be determined, as shown in FIG.
The scanning line number corresponding to the delivery control mark recognition unit 400
Transfer to. After the transfer is completed, the delivery control mark recognition unit 400 uses the start mark extraction unit 20 according to a command from the control unit 900.
The mark recognition target range is from the scanning line number of the start point 58 of the start mark transferred from 0 to the scanning line number of the end mark end point 59 transferred from the end mark extraction unit 300, and the sampling processing unit 500 Based on the processing result and the mark regulation information of the mark regulation information management unit 700, a delivery control mark that describes delivery control parameters such as destination designation and time designation is recognized. The recognition result is sent to the delivery processing unit 80.
Transferred to 0. After the transfer is completed, the delivery processing unit 800 reads the mail from the image memory 610 of the storage unit 600 based on the recognition result of the delivery control mark, and transfers the mail to the input/output interface unit 100.

FIG. 5 is a diagram showing an example of mark description according to this embodiment.

Destination specification parameters 63 from start mark 51 to end mark 55. Parameter 6 for specifying the number of pages and whether or not to use express delivery
This is an example in which a mark describing 4 and a time designation parameter 65 is recognized. On the other hand, for example, when setting the end mark 55 at the mark position 60, the mark of the time specification parameter 65 is not recognized and the mark area of the time specification parameter 65 cannot be used as the area of the mail body 66. , effective use of paper space can be achieved. Furthermore, when the end mark 55 is set at mark position 61, it is possible to recognize from the destination parameter 63 to the date of the time parameter 65, and when it is set at mark position 62, a new parameter can be added in addition to the above three parameters. I can do it.

It should be noted that from the above configuration and functions, it can be easily inferred that extraction of parameters for delivery control using handwritten character recognition instead of mark recognition for delivery control can also be realized. By using the start mark and end mark according to the present invention as paper reference marks in the character reading method according to the present invention (see Japanese Patent Application No. 57-221539), it is possible to realize a system in which the handwritten character reading area is variable.

In this way, in this embodiment, mark recognition is performed by determining the delivery control mark extraction area based on the discrimination result of the start mark and end mark. This has the advantage that positional fluctuations can be corrected and delivery control marks can be easily added or deleted without fixing the mark description format.

〔Effect of the invention〕

As described above, according to the present invention, paper space can be used effectively, and communication time and communication costs during mail delivery can be reduced.
