Abstract

PURPOSE:To efficiently execute communication of a mixture of character information and picture information, by providing a document preparation and edition processing section, picture input processing section, etc., and selecting a communicating system in accordance with the attribute of each information, such as character information, picture information, etc. CONSTITUTION:Character information prepared by a document preparation and edition processing section 10 of a word processor, etc., is accumulated in a document information memory section 11. On the other hand, picture information inputted by processing an already existing original from a picture input processing section 12 of a facsimile, etc., is accumulated in a picture information memory section 13. These character and picture information are processed by a header which discriminates the leading character and picture information of one page quantity at a transmitting communication processing section 16 after these information are layout-processed in accordance with a paper size by means of a layout processing section 14, and sent to a separation processing section 19 where these information are stored in a character information memory section 21 or picture information memory section 22 depending upon the header. Therefore, character information and picture information are respectively processed by a document preparation processing section 23 and picture input processing section 24 and the character information and picture information can effectively be communicated under a mixed state.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a mixed mode communication system that communicates by mixing text information and image information.

``Prior Art'' Conventionally, facsimiles have been developed as communication devices for transmitting existing systems a, but they do not have document creation or data processing functions. On the other hand, the spread of word 7''a is remarkable, as it is excellent in document creation and data processing.For this reason, the functions of both
It is thought that devices that communicate by combining text information and image information such as 7mm 7mm in a single page will become popular in the future.

However, conventional facsimile devices, such as the G3 facsimile, which communicates via a telephone network, scan and code existing manuscripts line by line, and use a data modem to transmit the coded data in one direction. Data error 1
! 1IIIlJil has not gone to 1A.

Therefore, when a code error occurs on the transmission path, image quality deteriorates. However, in communications such as facsimile, this does not pose a practical problem unless there are a large number of code errors. Literature (1981 IEICE General Conference 1159.5-
114 Examination of the image quality of 7mm r disotalfac.”
According to
This is not considered to be image quality deterioration, and the quality is acceptable as a received image. In addition, since the transmission frequency band of the data modem in G3 facsimile is almost equal to the telephone band, if error control is to be performed, the transmission/reception operation of the modem will be reversed and abnormalities in received data will be notified to the transmission line.
A heavy communication system (to) will be required. If the transmitting and receiving operations of the modem are reversed to perform this half-duplex communication system, modem switching time (turnaround time) is required, which increases communication time. Therefore, erroneous control is not performed in normal facsimile transmission of image data.

On the other hand, in character code transmission, even if a code error occurs in 1st or 5th, the characters will be represented as different characters. For this reason, an error system is essential for transmitting character code data expressing character information. Therefore, text information and images such as facsimile@! news and t-
When communicating by mixing characters on one page, if you use the error code system that is essential for transmission of character code 9, the turnaround time for half-duplex communication due to the error code control will cause problems with facsimiles, etc. This causes a significant deterioration in transmission efficiency for image data.

In addition, when communicating by mixing conventional character ↑H information and image information such as 7 aku 7 mm in one page, the character T7! ! In cases where text information or text information in any format is scattered on one page, the connection relationship of text information is not notified to the receiving side. Therefore, when processing document information on the receiving side, even if the documents are originally continuous, they can be processed as a series of documents. There was a drawback that there was no

This invention solves the problem of transmission that occurs when a single communication method is used to communicate an entire document in which text information and facsimile image bluishness are mixed on one page. In order to solve the problem of efficiency deterioration, text information and image i3! A communication method is selected in response to the characteristics of each information attribute such as information, and if necessary, the connection relationship of the character information extending between 'vl number Eno is notified to the receiving side. With this, it is possible to communicate efficiently by mixing text information and image information, and when notifying the connection relationship, the receiving side connects the text information across multiple pages and re-edits it as a continuous document. becomes possible.

In other words, in this invention, information and image information for character 1+ are created and stored independently, and a layout sentence v is created from the stored character information and image information in a layout such that these are mixed on one page. and accumulate. This Rayact document can be easily transmitted and received by setting only one character, one special character, or one image in its main scanning assembly number.

When all such layout documents are to be transmitted, the character information is sent by error-based @ communication, and the image/IIF information is sent by one-way communication.

Furthermore, in layout processing, for character information that continues on the next page, a continuation ↑;7ne is added to the layout document as necessary.

On the receiving side, the NIF record document is sent, and if an error is detected when receiving the characters 1a and 8, the error message is sent to the transmitting side, and the corresponding character 'II'7 is retransmitted. 11) When generating character r+V information and image information, the character information and image information are separated and stored. At this time, the character information having the continuation information is concatenated and subjected to IF multiplication, and these independently stored pieces of information are reproduced.

As described above, the present invention is a system that appropriately selects nine communication methods according to the characteristics of each information attribute, TT, TT character information, and 1flII image information. ．． When communicating mixed documents in an e-zo, there is less deterioration in transmission efficiency that occurs when a single communication method is used, and communication can be performed economically and efficiently by mixing text information and image information. can.

Furthermore, conventionally, when communicating text information and image information such as facsimile information mixed in a page, the connection relationship of text information that spans tI number of pages is not notified to the receiving side.

For this reason, when the document jT1 is processed on the receiving side, there is a drawback that even if the document is originally continuous, it cannot be processed as a series of documents.

But as mentioned? Receive the connection relationship of character information across 32 numbers! If you wish to notify t@,
That holding! ! In response to the notification indicating the relationship, it is possible to connect multiple pieces of character information between the characters (-) and to make it possible to re-collect #A on the receiving side.

"Embodiment" Figure W, 1 shows an embodiment of this invention, in which text information and ri! They are created independently from the iJ image information. Character information is created by the document creation and editing processing unit 10.The document creation and editing processing unit 10 is a word processor application on a general-purpose operating system (OS).
Character information created by a program, a dedicated word processor, etc. 0 Document creation 1 The character information created by the result processing section 10 is stored in a document information storage section 11 that stores document information. For example, character information C. and character information @C1 are stored, and the character code strings forming these character information are shown as CO and CI in the second column. These character information % Co and C1 are one-dimensional character code strings, and are IM on one page (-e-page).

- It is a data string that does not have layout information such as the number of characters in a row.

An existing manuscript is inputted from an image input processing unit 12 composed of an image input device such as a facsimile machine, scanned and encoded, and the obtained image information is, for example, 1. And Il is the image h! that accumulates image information! The information is stored in the first report memory section 13. The image data string constituting the image information Za and the image information 11 at this time is m
Work on figure z. and Il. The image data string is encoded by MH (Modified Huffman), MR (Modified Read), MMR (Modified Modified Read), etc., which are encoding methods such as 7AQIJ, or uncompressed. Line 1rrJ period for each line ^
At the end of a continuous image data string, an image data string end signal (RTC) is input to facilitate line-by-line editing processing.

Next, these individually created hi character information CG, C.

and image information I., Il are input from the document information memory section 11 and the image information memory section 13 to the layout processing section 14, and layout processing is performed according to the size of one paper.This example is as shown in FIG. In case of K layout, this document has 3 pages (Pi tP snow,
P3), and the first page P1 consists of character information CO such as title, address, outline, etc., and image information 1o such as handwritten notes, @name, map, etc. Text information CI such as main text
The second-fourth page P3 and the third page P3 and Kt are divided into nine parts and laid out. The 3rd e-page P3 includes some character information C1 such as the main text, handwritten memos, signatures, maps, etc.
It consists of image information 11 such as photographs. For ease of layout processing, each page has only text information and image information in the main scanning direction, in this example, in the lateral direction of the page, without coexistence of text information and image information.

The layout processing unit 14 processes one character information C.

Regarding C1, the number of characters in one line that matches the paper size is counted, and the line is automatically inserted and processed sequentially.

The line feed pitch is set in advance. The layout processed document in row 5n is stored in the layout processed document memory unit 15 that stores the layout processed documents by performing such a character string pouring operation outside the image area determined by the image information l6eIl. The layout document consists of one character information C, CI and image information, as shown in Figure 4AK.
・In order to separate +11, a header that identifies text information and image information is placed at the beginning of one page of data and at the position where text information and image information are switched, and a length identifier LI that indicates the data length of the text data string. It consists of a single character information body and an image information body.

The header C8 is character data, and indicates that the character data is not continuous across 1-Z.

The header 〇 is character data and indicates that the character data is continuous across pages.Header 1.
is image data and indicates that the image data is not continuous across pages, and header Xc is image data and indicates that the image data is continuous across pages K. on the other hand.

The end of image data can be identified by the image data string end signal (RTC), and the length identifier L! indicates the data length of the image data string. may also be used.

Next, the civil official whose layout has been processed in this manner is sent from the layout processed document memory section 15, and this transmission is performed as follows.

What about the transmission communication processing section 16? As shown in the JS4 diagram, the character information at the beginning of one page of data and ii! If it is one character information (C8 or Cc), -shi control is performed, and if it is image information (I, M9 is I,), one-way communication is performed according to the header that identifies the image information.

That is, as shown in FIG. 4B, if the header is C8, character information is transmitted in the frame structure (F'6 Fl Fl Fs-Fn) used in the )IDLc procedure etc. in order to perform error control. When the reception communication processing unit 17 detects an error in this frame, the receiving side returns the error detected frame number (+1*1 p2 s3·n) as a response signal F□. At this time, if there is an error frame, the transmitting side retransmits the frame with the error.

Next, when a header indicating 1 chair information is detected on the same page, what happens? Switch from AC control mode to one-way communication mode. In other words, 1 image information is 037727% IJ
The image signal PIX is transmitted in the same procedure as above, and when the transfer of one page of document information is completed.

A page end signal P is transmitted, and if the receiving side has received one page normally, it returns a (-) confirmation 1 number P□□. Thereafter, in the same way, each (-zo is sent 6), and when the transmission of the transmitted document is completed, . is sent (at, and the receiving side is D□
Return □.

It is received by the image reception communication processing section 17 on the image reception side.

And after the retransmission correction has been made for the pb frame.

All documents, in this example page PI sP!, are stored in the layout document memory section 1B. *P 婁 is stored.

In order to separate this layout document into character information and image information, the separation processing section 19 is used to separate the layout document memory section 1.
8. If the received and stored layout document is read out, and if it indicates character information according to its header, the character information is extracted for the length of the character data string indicated by the length identifier LI, and if the header is character data. In the case of continuous Ce that spans between pages, the brush length is L! Continuously extract each character data corresponding to the length of the circle character data indicated by and the length of the character data indicated by the identifier LIK indicating the length of the character data of the first page, and As shown, it is stored in the document information memory section 21 as the characters f/l information Cs. In this way, the position on the paper, C., 0-fold, which is only character information without layout information such as the number of characters in a line, is stored in the document information memory section 21, and similarly as on the image information book sending side. I, I in Figure 2
1 similar to heavy! ! 17 Image information is both values/information memory fA2
2. Therefore, this character information cos C1 is processed by a document creation bias processing unit 23 such as a general-purpose word processor.
The image information In, 11 can be printed as characters or displayed on a display, and similarly, the image information In, 11 can be recorded and displayed in an image input processing section 24 of a general-purpose facsimile machine or the like.

``Effects of the Invention'' As explained above, in a communication device such as a facsimile, a communication device such as a facsimile has a document creation/editing processing section, an image input processing section, a memory section, a layout processing section, a transmission/reception communication processing section, From K.

Each information attribute, such as one character information and one image information, solves the deterioration in transmission efficiency that occurs when a single communication method is used when communicating documents in which text information and image information such as facsimile are mixed on the page. Choose the appropriate communication method according to your understanding. It is possible to communicate with a mixture of information. In addition, as in the example above, when notifying the receiving side of the connection relationship of text information and image information that spans multiple pages, the receiving side connects the text information and image information that spans multiple pages, and It is possible to re-edit as .
