This type of mail processing system reads, for example, an address or a zip code written on a mail set on a sorting machine by a recognition unit of an optical character reader, and sorts the mail based on the corresponding sorting information. Each postal item or postal area is classified and postal items whose address or postal code could not be read are collectively classified as rejected postal items.

[0003] The mail (rejected letter) whose address or zip code could not be read is compressed as an entire image into code data and temporarily stored in the image memory of the storage / distribution device. The video data is distributed to a plurality of video coding terminals for each category. At each video coding terminal, the distributed image is decompressed from the code data and displayed on a display unit. Is input (coding process), the rejected mail is set again in the sorting machine by the code, and the sorting process is performed using the correspondingly input code.

[0004] This makes it possible to compensate for the limitations of the machine division by the optical character reader. However, in the above-described mail processing system, only multi-value data is used for inputting a mail image. In addition, the compression parameter used when compressing and using multi-valued data has been constant.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a mail processing system according to the present invention. This mail processing system includes a reading sorting machine 1 and a video coding system 2.

The reading / sorting machine 1 reads an address and a postal code on the postal matter P, recognizes the address and the postal code from the read contents, and recognizes the address, the postal code recognition result or the address from the video coding system 2. This is a sorting machine that sorts postal items P by postal code, and prints a bar code corresponding to the recognition result on each postal item P.

In the reading / sorting machine 1, for example, a plurality of mails are set in batches (lots) or in mails rejected for the batches, and the set mails P,. A supply unit 10 for supplying, a scanner unit 11 for reading the entire image on each mail P supplied by the supply unit 10, a scanner unit 1,
1, an ID code reading unit 12 serving as a photoelectric conversion unit that reads a bar code corresponding to an image number assigned to the postal matter P passing through the mail item P. A bar code print unit 13 for printing a bar code corresponding to a number or a bar code corresponding to an image number; a postal matter P passing through the bar code print unit 13; The sorting unit 14 sorts mail P based on predetermined sorting information (sorting box number) corresponding to the code, and sorts postal items whose address and zip code could not be recognized into a reject storage. A recognizing unit 15 for recognizing an image number as an address, a postal code or a bar code read content from the ID code reading unit 12; Part conveyance control unit 1 for controlling the conveyance of postal matter P from the supply portion 10 of the main body 1a to the classification unit 14

The supply unit 10, the scanner unit 11, the ID code reading unit 12, the barcode printing unit 13, and the sorting unit 14 are provided in the transport sorting unit main body 1a.
When the image number (serial number) as the barcode recognition result is supplied from the recognition unit 15, the control unit 16 outputs the image number to the coding content storage control unit 34, or transmits the code, A code corresponding to the address or postal code from the section 15 is output to the barcode printing section 13.

The transport section main body 1a has a mechanism including a supply section 10, a scanner section 11, a bar code print section 13, and a section section 14. The operation panel 18 has, for example, a changeover switch for switching between New Year's mail and ordinary mail, and a changeover switch for switching between reading of only the postal code or reading of the postal code and address.

The transport control unit 17 is provided with 22K / h and 30K / h
h, and when the reading of only the postal code is designated by the changeover switch of the operation panel 18, the control is performed at the conveying speed of 30 K / h, and the reading of the postal code and the address are designated. In this case, control is performed at a transport speed of 22 K / h.

The scanner section 11 has a multi-valued and binary compression method. As the multi-valued compression method, for example, a DCT (discrete cosine transform, discrete cosine transform) method of JPEG (Joint Photographic Coding Expert Group) is used. Are used, and “20” and “30” are used as the values of the Q factor that is the reference of the compression parameter.
The larger the compression parameter, the higher the compression ratio. For example, when the reading of only the postal code is designated by the changeover switch of the operation panel 18, "30" having the larger compression ratio is used as the compression parameter, and the reading of the postal code and the address is designated. In this case, the compression parameter “20” with the smaller compression rate is used as the compression parameter.
Is used. As a binary compression method, for example, MR
(Modified Read), and K = 8 is used as the parameter.

As shown in FIG. 2, the recognizing unit 15 detects, from the image supplied from the photoelectric conversion unit 11a, an area in which an address and a postal code are described in the form and position of the area. A detecting section 21; a character line detecting section 22 for detecting a character line in which an address and a postal code are described in the area detected by the area detecting section 21;
The character detecting unit 23 detects and cuts out the characters of the character line detected one by one, that is, detects and cuts out the character information corresponding to the address (postal code). A reference pattern of two types of characters, a reference pattern in a direction predetermined for each character in the character / address dictionary 25 and a reference pattern in a direction rotated by 90 degrees with respect to that direction. Recognition by matching methods with these reference patterns, etc., and reject attributes (discrimination of handwritten or printed type / rejected character information / recognition result of read characters / words) and recognition result Character / address recognizing unit 24 for generating rejected data, an image memory 26 storing an image supplied from the photoelectric conversion unit 11a, -Object attribute (handwritten or printed print distinction / reject character information / read character-word recognition result), the recognition result to the reject data corresponding, and the image from the image memory 26 the video coding system 2
And a reject data control unit 27 for outputting to The character / address recognizing unit 24 is further adapted to distinguish between handwritten and printed characters, and to determine the writing direction of the address and postal code. As a method for distinguishing handwritten or printed type, for example, it is performed as described in JP-A-64-14682. That is, a parameter that is a characteristic of the read character is extracted, and the parameter is compared with a reference value to determine whether the character is a handwritten character or a print character.

The parameters include (1) the height of the character, (2) the lower end position of the character, (3) the width of the character, (4) the pitch of the character, (5) the area of the character, and (6) the line. , (7) Leftmost character position of line, (8) Line spacing.

As for the writing direction of the address and the postal code, the writing direction is determined based on which of the two reference patterns for each character in the character / address dictionary 25 has been recognized. For example, if a character is recognized by a reference pattern in a predetermined direction among the above two types of reference patterns, the line direction is already known by the character line detection unit 22. The writing direction is determined based on and the direction of the line. The reject data control unit 27 rejects data according to a reject attribute, a recognition result (partially recognized address and postal code as recognition contents up to the middle of the recognizing unit 15), and a mail whose address or postal code cannot be recognized. An image of the object P is output.

The reject attributes include whether the address and the postal code are described by hand, whether the address and the postal code are described in print type, the direction in which the address and the postal code are described, and the like.

The recognition section 15 has a bar code recognition section (not shown) for recognizing a bar code (image number: serial number) from the image supplied from the ID code reading section 12. The content recognized by the barcode recognition unit is output to the control unit 16.

The video coding system 2 comprises an image distribution server 3 and video coding terminals 4,. The image distribution server 3 determines whether the reject attribute (discrimination of handwritten or printed type / reject character information / read character /
The category is determined according to the word recognition result) and the reject data according to the recognition result, and distributed (distributed) to the video coding terminals 4,... Corresponding to this category, as shown in FIG. , A memory control unit 31, an image memory 32, a video distribution control unit 33, a coding content storage control unit 34, and a desk input / output control unit 35.

The categories include postal code vertical horizontal writing, postal code reverse horizontal writing, postal code horizontal writing, address vertical writing, address reverse vertical writing, address vertical writing, and address vertical writing. It is written horizontally. However, when reading only the postal code, the category for the postal code is valid.

The memory control unit 31 rejects the reject attribute from the reject data control unit 27 and rejects according to the recognition result (partially recognized address and zip code as recognition contents up to the middle of the image recognition unit 15). The data and the read image of the mail P are supplied, and the reject attribute and the reject data are output to the video distribution control unit 33.
The image is converted into compressed code data as described later and output to the image memory 26. Further, the memory control unit 31 outputs an image stored in the image memory 32 to the corresponding video coding terminal 4 in accordance with the distribution content from the video distribution control unit 33. The image memory 32 sequentially stores images supplied from the memory control unit 31 in the order of image numbers (serial numbers).
The video distribution control unit 33 determines a category based on the reject attribute and reject data supplied from the memory control unit 31, classifies the category for each corresponding category number,
It is stored and managed by the image number (serial number) assigned to each image.

The memory control unit 31 indicates various modes designated by a changeover switch on the operation panel 18 supplied from the control unit 16 (whether a mail to be processed is a New Year's mail or a regular mail, In response to the control signal, the image data from the reject data control unit 27 is converted into code data compressed by the corresponding compression method and compression ratio, as shown in FIG. In addition, a header including a flag indicating a compression method and a compression parameter is added to this code data, and the code data is output to the image memory 26. The flag indicating the header compression method is, for example, “01” indicating multi-value, “10” indicating binary, and “11” indicating non-compression. Uncompressed is used when handling images without compression.

The memory control unit 31 checks the remaining capacity of the image memory 32, and if the remaining capacity is small, increases the compression ratio. The video distribution control unit 33 has a category classification table 33a and a terminal category table 33b.

The category classification table 33a classifies each of the determined categories, that is, each category number, and stores and manages the image numbers (serial numbers) assigned to the respective images.

Thus, when stored in the image memory 32, the video distribution control unit 33 determines the category based on the supplied reject attribute and reject data, and stores each image in the storage area of the corresponding category number in the category classification table 33a. The image numbers assigned to each category are sequentially stored, and when the images are distributed, the image numbers are deleted from the storage area of the corresponding category numbers.

In the terminal category table 33b, processing categories of the respective video coding terminals 4,... Are stored in advance in the order of priority. For example, when a power supply (not shown) is turned on in response to an instruction from each video coding terminal 4, It is configured to be stored and set in advance.

The coding content storage control unit 34
The code and image number from the desk input / output control unit 35 are stored, and an image distribution request wait signal (a similar signal is obtained when the power of the video coding terminal 4 is turned on) due to the code input corresponding to the image number. Is output to the video distribution control unit 33, and the code stored in response to the inquiry by the image number from the control unit 16 in the reading and sorting machine 1 is stored in the control unit 1
6 is output. The desk input / output control unit 35
The input unit 4b receives an input from the input unit 4b of each video coding terminal 4, and outputs a code and an image number corresponding to an address, a postal code, and the like from the input unit 4b to the coding content storage control unit 34.

Each of the video coding terminals 4 has an image display unit 4a such as a CRT and an input unit 4 such as a keyboard.
b, and expands the code data from the image memory 32 by a decompression processing circuit (not shown) in accordance with a flag indicating a compression scheme of a header added to the code data and a compression parameter (the compression process described above). The image which has been obtained by the inverse conversion of the processing) is displayed on the image display unit 4.
The operator inputs a code corresponding to the destination name and zip code of the displayed image by the input unit 4b. The codes corresponding to the destination name and postal code input to the input unit 4b are output to the desk input / output control unit 35 together with the image numbers.

Next, the operation of the above configuration will be described with reference to the flowchart shown in FIG. First, a changeover switch on the operation panel 18 is used to specify a mode according to whether the mail to be processed is New Year's mail or ordinary mail, and whether the contents to be read are only the postal code or address.
1).

In response to the designation, the control section 16 controls the transport control section 17 to control the transport of the mail P at 22 K / h or 30 K / h (S2). Further, the control unit 16 sends a control signal indicating the specified mode to the memory control unit 3.
Output to 1.

In such a state, a plurality of mail items are set in the reading / sorting machine 1 in batches, and the set mail items P,. The entire image on each postal matter P is read by the photoelectric conversion unit 11a of the scanner unit 11. The read contents of the photoelectric conversion unit 11a are supplied to a recognition unit 15, where the address and the postal code are recognized. The recognition result is supplied to a control unit 16. Thereby, the control unit 16 outputs a code corresponding to the address and the postal code to the barcode printing unit 13 when the address and the postal code are recognized, and outputs the code when the address and the postal code are not recognized. A code indicating an image number corresponding to the image is output to the barcode printing unit 13. As a result, the barcode printing unit 13 prints a barcode corresponding to an address, a zip code, or a barcode corresponding to an image number on the mail P that has passed from the scanner unit 11 to the ID code reading unit 12. Next, the sorting unit 14 addresses the mail P which has passed through the barcode printing unit 13, sorts the mail P based on predetermined sorting information (sort box number) corresponding to the recognition result of the postal code, and sorts the mail P. Mail items whose zip code could not be recognized are sorted into the reject storage.

In the same manner, the sorting machine 1 sorts batches of mail P,. The mails P,... Rejected to the reject box are set in the reading / sorting machine 1, and the set mails P,.
Is supplied by the supply unit 10 one by one, and the supplied barcodes on the postal matter P are read by the ID code reading unit 12 and recognized by the barcode recognition unit of the recognition unit 15. It is supplied to the control unit 16. As a result, the control unit 16 is supplied with the image number (serial number) as the barcode recognition result, and outputs the image number to the coding content storage control unit 34 to transmit the code transmitted to the barcode print unit 13. Output.

Thus, the bar code printing unit 13
Prints a barcode corresponding to the above code on the postal matter P that has passed through the scanner unit 11. Next, the sorting section 14 sorts the postal matter P that has passed through the barcode printing section 13 based on predetermined sorting information (sorting box number) corresponding to the code.

If the recognizing unit 15 of the reading / sorting machine 1 can only partially recognize the address and the postal code, the reject data control unit 27 sends the reject attribute and the recognition result (recognition up to the middle of the recognizing unit 15). The reject data corresponding to the partially recognized address and postal code as contents and the read image of the postal matter P from the image memory 26 are supplied to the memory control unit 31 in the image distribution server 3.

The memory control unit 31 outputs the supplied reject attribute and reject data to the video distribution control unit 33, and compresses the read image using a compression method and a compression ratio corresponding to the control signal supplied from the control unit 16. The data is converted into code data (S3 to S9), a header including a flag indicating a compression method and a compression parameter is added to the code data, and the code data is output to the image memory 32 and stored in the image memory 32 corresponding to the image number. (S10).

The video distribution control unit 33 determines the category based on the sequentially supplied reject attribute and reject data, and stores the image number assigned to each image in the storage area of the corresponding category number in the category classification table 33a. Are stored in order.

In such a state, the processing of the image distribution server 3 will be described. That is, the video distribution control unit 33
In response to the image distribution request signal from the video coding terminal 4, the top priority category of the video coding terminal 4 is checked with reference to the terminal category table 33b, and the image is started from the top of the area of the category classification table 33a corresponding to this category. The number is read out, and the image number and the data indicating the video coding terminal 4 to be distributed are output to the memory control unit 31 as distribution contents. When the content of the distribution is output, the video distribution control unit 33 deletes the image number from the category classification table 33a. Further, the memory control unit 31 outputs the image and the image number stored in the image memory 32 to the corresponding video coding terminal 4 according to the distribution contents.

Also, when an image distribution request signal is obtained from another video coding terminal 4, the same operation as described above is performed. As a result of the above image distribution, the code data supplied from the image memory 32 in the image display unit 4a of the video coding terminal 4 is compressed by a decompression processing circuit (not shown) into a header attached to the code data. An image of the postal matter expanded according to the flag indicating the method and the compression parameter is displayed (S11 to S1).
4). The operator inputs a code corresponding to the address and postal code that could not be recognized in accordance with this display through the input unit 25. Then, the code and the image number corresponding to the address or postal code input by the input unit 25 of the video coding terminal 4 are output to the coding content storage control unit 34 via the desk input / output control unit 35. Thus, the coding content storage control unit 34 stores the code and the image number, and outputs to the video distribution control unit 33 that the code has been input for the image number, that is, an image distribution request signal.

Codes corresponding to the address and postal code which could not be recognized by the other video coding terminals 4 are input and operate in the same manner. As described above, the transport speed of the mail, the method of compressing the image, and the compression ratio are changed according to the type of the mail to be processed.

As a result, high quality processing can be performed on mail that requires high image quality, and processing speed is high and mail data transfer efficiency is high for mail that requires low image quality. In addition, a large amount of compressed images can be registered because the use area of the image memory is small, and overflow of the image memory can be prevented.

The case where the compression ratio is changed in accordance with the instruction of the changeover switch on the operation panel has been described. However, the present invention is not limited to this. The histogram of the image read by the scanner is taken and the compression ratio is changed based on this histogram. May be.

[0047]

As described above in detail, according to the present invention, it is possible to perform high image quality processing on postal matter requiring high image quality, and to process postal matter which requires low image quality. A mail processing system that is fast, has high image data transfer efficiency, uses a small area of image memory, can register a large amount of compressed images, and can prevent overflow.
And mail handling methods .
