Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image data processing apparatus such as a facsimile that handles information such as documents and graphics as image data, and more particularly to an improvement in its printing and communication technology.

[Conventional technology]

Conventionally, a document communication system using a public line includes a teletex which handles character information and a facsimile which handles image information. In the facsimile, a document such as a character or a figure is raster-scanned on a transmission side and is transmitted after being decomposed into an electric signal. The reception side scans the document synchronously therewith and immediately print-records the received document. In facsimile,
As described in Japanese Patent No. 29160, there is a device having a memory receiving function of temporarily registering data of a received document in a storage device such as a hard disk or a semiconductor memory and not immediately printing and recording the data. The facsimile disclosed in the above publication temporarily stores the received document data in a storage device, searches the stored document data, displays the retrieved document data on a graphic display, and confirms the operator with the unnecessary document data such as a direct mail. This is to prevent printing and prevent wasteful consumption of recording paper.

[Problems to be solved by the invention]

However, in an image data processing apparatus such as a facsimile which has a memory receiving function and does not have a display means for displaying an image of document data such as a graphic display, a method in which a user confirms a content image of a received document registered in a storage device There is no other method than printing, and the contents of a document can only be understood by printing. Therefore, there is a problem that it is difficult to intuitively understand what kind of document is registered in the storage device without the display means. This wastes recording paper and increases printing costs. This is the same for those having a function of registering a transmission document.

In addition, when a document covering a plurality of pages is transmitted from the transmitting side, the transmitting side transmits all pages regardless of whether the document is necessary on the receiving side. Therefore, unnecessary page transmission on the transmitting side and waste on the receiving side are performed. There is a possibility that the printing time will be prolonged and the printing time will be long, and the cost required for them will be wasted. In addition, when the above-described document of a plurality of pages is received, there is a problem that the receiving side having no display means cannot understand the document contents unless all the pages are printed, and cannot retrieve only necessary pages.

Further, when the document is a full-color image, if the above-described transmission and printing are performed, the color image has a much larger amount of information than a black-and-white image, so that there is a problem that the cost required for communication and printing is further increased.

The present invention has been made in view of such circumstances, and when a document to be transmitted or a document registered in a storage device extends over a plurality of pages, a representative page in which the document of each of those pages is reduced and arranged on one page is used. By creating the document, it is possible to intuitively understand the contents of the document, shorten the printing time, suppress communication and printing costs, and, when transmitting a document that includes a plurality of pages, transmit the representative page and send the document from the representative page. An object of the present invention is to provide an image data processing apparatus capable of reducing the communication and printing costs by grasping the contents and taking out only necessary pages, and processing color images at low cost.

[Means for solving the problem]

The image data processing apparatus of the present invention reads image data of a document including a plurality of pages, and receives an image transmission apparatus that transmits the read image data, and the transmitted image data.
An image data processing apparatus comprising: an image receiving apparatus that prints received image data; wherein the image transmitting apparatus includes: a unit configured to reduce read image data; and a representative unit configured to arrange reduced image data of a plurality of pages on one page. Comprising a creating means for creating a page, the image receiving device, means for receiving and printing the created representative page, based on the print result, means for selecting image data of any page in the representative page, Means for transmitting the selected image data from the image transmission device.

[Action]

In the present invention, when the image transmitting apparatus transmits a representative page, the image receiving apparatus prints the representative page, selects image data on a page-by-page basis according to the content of each printed representative page, and receives an image from the image transmitting apparatus. Only the image data of the page selected by the device is transmitted. As a result, only pages having necessary contents can be selected, and transmission costs and printing costs can be reduced.

〔Example〕

Hereinafter, the present invention will be described with reference to the drawings showing the embodiments. FIG. 1 is a block diagram showing a configuration of a facsimile apparatus (hereinafter, referred to as an apparatus of the present invention) which is an image data processing apparatus according to the present invention.

The keypad 4 is connected to an interface 7, through which the keypad 4 is connected to a central control unit 8 using a microcomputer that controls the entire apparatus. A printer 5 for outputting image data is provided on the interface 7.
And a scanner 6 for reading an image. The central control unit 8 is connected to a document memory 9 using storage means such as a hard disk and a semiconductor memory for storing received or transmitted documents.
System memory in which system programs are stored
10, Page memory 1 for expanding one page of document data
3, a semiconductor memory such as a representative page memory 14 for expanding a representative page and a work memory 15 used for various processes at the time of creating a representative page and the like, and an encoding / decoding unit 12 used for expanding document data in each semiconductor memory. It is connected.

The representative page memory 14 is for developing a document of a predetermined maximum number of pages (the number of divisions) described later, and the development position PSP is predetermined in the order of pages.

Further, a communication control unit 11 for connecting the device to a public line is also connected to the central control unit 8.

Next, a process for confirming document data registered in the document memory 9 by the apparatus of the present invention will be described. In this confirmation processing, the document data registered in the document memory 9 is selected, and a representative page is created by reducing the image of each page and arranging it according to the number of pages, and outputs it.

First, the user selects whether to use the changed values or the default values for the following four modes.

(1) Print mode when receiving a document (default :) Print Not print (2) Representative page output mode (default :) Output only the document content page Only representative page is output Representative page and selected document content page output Representative page and all documents Contents page output (3) Registered document confirmation mode (default :) All registered documents All registered received documents Received documents for each communication All registered transmitted documents Transmitted documents for each transmission (4) Valid document in representative page Page maximum number setting mode (default :) Automatic 1 page 4 page 9 page 16 page 25 page 36 page 49 other: page 64 The last mode here is the maximum number of pages of document data displayed in the representative page (number of divisions). Is set.
The default value of "auto" automatically sets the maximum number of pages according to the number of content pages of the valid document.

When the mode setting is completed, the received document management menu is
The document data to be displayed on the LCD 1 and output the representative page is selected by operating the keypad 4. FIG. 2 shows a display example of the LCD 1, and FIG. 2 (a) shows a display example of the received document management menu. On this screen, three documents are displayed, and the document of number 3 indicates that the representative page has not been printed yet. Then, the user inputs 3 on the keypad 4 to select the number 3, and inputs YES on the keypad 4 on the screen shown in FIG. 2B to print the representative page of the selected document and its contents page. When YES is input, the screen displays that the representative page is to be printed as shown in FIG. 2 (c).

FIG. 3 is a flowchart showing a processing procedure of the printing process. First, a setting process of a maximum number of valid document pages in a representative page (hereinafter referred to as a maximum page number) is performed (step #).
1). In this processing, the number of divisions of the representative page, that is, the maximum number of pages dp indicating the number of content pages to be printed on the representative page, and the horizontal reduction rate hs and the vertical reduction rate vs based on the maximum number dp are set.

FIG. 4 is a flowchart showing the contents of this processing. It is determined whether or not to automatically set the maximum number of pages dp by the input key of the keypad 4 in the maximum number of pages setting mode (step # 20). When the 1 "key is pressed and automatic is set, steps # 21 to
In step # 32, the maximum number of pages dp is automatically set. If the "2" to "8" keys are input during the mode setting, the maximum number of pages dp according to the input keys is set in steps # 33 to # 46. If the number of content pages is greater than 50, the maximum number of pages is set to dp = 64. The horizontal and vertical reduction rates hs and vs are set based on the set maximum number of pages dp. When the same reduction ratio is set in the vertical and horizontal directions, the reduction ratios hs and vs are set by the square root of the maximum number of pages dp. When these settings are completed, the number of content pages dp of the document is set (step # 2), and the work variable bpw of the number of content pages for counting the number of content pages bp and the variable dn indicating the number of representative pages are set to 1. It is set (step # 3), and the work variable dpw of the maximum number of pages for counting the maximum number of pages dp is set to 1 (step # 4). Next, the work variable bpw
The image data of the content page of the value of is developed in the system memory 10 (step # 5). Then, the image data having the content page number of bpw in the system memory 10 is supplied to the code decoder 12 to be decoded, and is developed in the page memory 13 (step # 6). Next, set the reduction ratio of the expanded image data
The size is reduced according to hs, vs, and expanded in the work memory 15 (step # 7). The reduced image data expanded in the work memory 15 is expanded to a predetermined position PSP (dpw) corresponding to the number of pages in the representative page memory 14 (step # 8), and the value of the work variable bpw is changed to the position PSP in the representative page memory 14. (Dpw)
(Step # 9).

Then, the work variable bpw is compared with the content page number bp,
It is checked whether or not all the content pages have been used as representative pages (step # 10). When the work variable bpw is smaller than the number of content pages bp, there are still unused document content pages, so the work variable dpw is compared with the maximum number of pages dp to determine whether one representative page has been filled with the content pages. Is checked (step # 11).

If the work variable dpw is smaller than the maximum number of pages dp and has not been satisfied yet, the process proceeds to step # 15.
Increment dpw, bpw by 1 and return to step # 5,
The next content page is processed.

If the work variable bpw is not smaller than the content page number bp in step # 10, the processing of all the content pages has been completed, so the process proceeds to step # 16, where the number of the received document management list menu shown in FIG. The received document identification information including items such as the transmission destination and the representative page number dn are developed at the top of the representative page, and the representative page is printed by the printer 5 in the next step # 17. Then, as shown in FIG. 2 (d), it is determined whether or not to print the content page by inputting the content page number (step # 18). ), The content page number is selected, the selected content page is printed (step # 19), and the process ends.

On the other hand, in step # 11, the work variable dpw is set to the maximum page number p.
If it is not smaller than d, the representative page is printed in step # 12 and step # 13 by the same processing as step # 16 and step # 17, the representative page number dn and the work variable bpw are incremented by one, and the next representative page is printed. The process returns to step # 4 to perform the above processing.

FIG. 5 is a diagram showing the flow of data when the maximum number of pages dp = 4 and the number of content pages bp = 4. The image data of a 4-page document stored in the document memory 9 is stored in the system memory one page at a time. Expanded to 10, decrypted and page memory 13
Will be expanded to. And the reduction ratio h in which the image data is set
Reduced according to s, vs, reduced image data is stored in work memory
Expanded to 15, the upper left position PSP of the representative page memory
Expanded to (1). Similarly, position PSP (2), PSP
(3) The reduced image data of 2, 3, and 4 pages are sequentially developed on the PSP (4) to create a representative page, which is printed by the printer 5.

FIG. 6 is a diagram showing an example of the output of a representative page. Image data for four pages is reduced and appropriately arranged to create a representative page.

In this way, even if the document registered in the document memory 9 is a plurality of pages, the document content image can be easily confirmed.

In the present embodiment, the received document registered in the document memory 9 has been described as an example. However, the same can be easily confirmed for the transmission registered document and all the documents registered in the document memory 9.

Next, another embodiment of the present invention will be described. In this embodiment, processing for transmitting a document of a plurality of content pages will be described.

When transmitting documents of a plurality of content pages, three transmission modes can be selected.

Send representative page and content page Send only representative page When sending only content page, send the representative page first and then send the content page. When the representative page to be transmitted is not only divided into four parts of the representative page memory 14 but also divided into nine parts, sixteen parts, etc., by changing the reduction ratio of the content page, one representative page can be obtained from the nine page image and the 16 page image. Can be created and sent.

FIG. 7 is a flowchart showing the processing contents when transmitting a document of a plurality of content pages. First, it is determined whether or not to create a representative page according to the set mode (step # 50). If the representative page is not to be created, the process proceeds to step # 75, where it is set whether or not to transmit the content page. Then, the content page is transmitted (step # 76).

When a representative page is to be created, one image data is input by the scanner 6 and developed into one page (page) in the page memory 13 (step # 51). Next, page memory 13
The image data for one sheet expanded in the above is supplied to the code decoding unit 12, compressed into code data, and stored in the document memory 9 (step # 52). These steps # 51 to # 52 are repeated until all the content pages are input (step # 5
3). When all the content pages are stored in the document memory 9,
The representative page division number, that is, the maximum page number dp is set (step # 54). This step is the same as in FIG.

Then set the total content page number bp and the work variable
bpw, the work variable dpw of the maximum page number dp, and the page number dn of the representative page are set to 1 (step # 55).

Next, the code data stored in the document memory 9 is read out (step # 56), and supplied to the code decoder 12 to decompress and generate image data (step # 57). The generated image data is expanded in the page memory 13 (step # 5).
8) These steps # 56 to # 58 are repeated until one content page is completed (step # 59). 1
When the image data for one sheet is expanded in the page memory 13, it is reduced at the set reduction ratio hs, vs (step # 6).
0). Then, it is determined whether or not to use the work memory 15 (step # 61).
The reduced image data is expanded in the work memory 15 (step # 62), and is stored in the representative page memory 14 at the position PSP (dp
w) (Step # 63). Work memory 15
Is not used, the reduced image data is directly developed at the position PSP (dpw) of the representative page memory 14 (step # 64).

In this case, the generation of the address of the reduced image data is more complicated than when the work memory 15 is used. Until the development of one content page into the representative page memory 14 is completed, the processing of steps # 62 to # 64 is repeated, and
When the development of the image data for one sheet to the representative page memory 14 is completed, the work variable bpw is compared with the content page number bp,
It is checked whether or not all the content pages have been used as representative pages (step # 66). If the work variable bpw is smaller than the number of content pages bp, the work variable dpw is compared with the maximum number of pages dp to check whether one representative page has been filled with the content pages (step # 67). When the work variable dpw is smaller than the maximum number of pages dp, the representative page is not filled with the content pages, so the work variable dpw,
bpw is incremented by 1 (step # 68), and the process returns to step # 56 to repeat the processing for the next content page.

On the other hand, in step # 66, the work variable bpw is changed to the content page number b.
If it is larger than p, all the content pages have been used as representative pages, so the image data expanded in the representative page memory 14 is compressed and encoded into coded data (step # 7).
2) and record it in the document memory 9 (step # 7)
3). Then, the code data of all the representative pages is sequentially transmitted via the communication control unit 11 (step # 74). Then, for example, it is determined whether or not the content page is to be transmitted according to a request from the receiving side (step # 75). If the content page is to be transmitted due to a request or the like, the content page is transmitted (step # 75).
76), end. If no transmission is to be made, the process ends.

In step # 67, the work variable dpw is set to the maximum number of pages dp.
If it is larger, one representative page is filled with the content page, so the image data in the representative page memory 14 is compressed and encoded into code data (step # 69), and the code data is recorded in the document memory 9. (Step # 70), the work variable dpw is set to 1, the work variable bpw is incremented by 1, the page number dn of the representative page is incremented by 1 (Step # 71), and the process proceeds to the next representative page content page. The process returns to step # 56.

In the representative page transmission process, a representative page number is added to the upper part of the representative page as in the above-described embodiment.
Since the process of assigning the content page number to the upper left of each content page is the same, the description is omitted.

FIG. 8 is a diagram showing a data flow when one representative page is created from four content pages.
, And decodes the content page stored in the document memory 9 and transfers it to the page memory 13 in order from the first page, reduces it, and directly or via the work memory 15 to the expanded position PSP ( dpw). The print result of the content page and the content (representative page) of the representative page memory 14 is the same as that shown in FIG.

Next, still another embodiment of the present invention will be described. In this embodiment, a procedure in which the receiving side that has received the representative page created by the transmitting side and then selects a content page will be described in detail.

The configuration of this embodiment is basically the same as that shown in FIG. 1, but the document memory 9 and the representative page memory 14 are not necessarily required in the facsimile machine on the receiving side. Further, in this embodiment, the facsimile apparatus having the transmission document is terminal A, the facsimile apparatus to be transmitted is terminal B, and both terminals A,
Communication between B shall be performed in accordance with CCITT Recommendation T.62 "Control procedure for Teletex and Group 4 facsimile service". Further, the representative page is as shown in FIG. 6, and the creation procedure is the same as that of the second embodiment, and the description is omitted. The page number of the representative page is given at the top of the representative page, and the page number of each representative page is given at the top left of each content page in the representative page.

 Next, an outline of the operation procedure will be described.

First, the terminal A transmits a representative page to the terminal B by a normal document transmission procedure. At this time, the terminal A stores the page identification information of the transmission document in the work memory 15. That is, in this embodiment, the content page is represented by the representative page number and its page number, and is not represented by the content page number as in the above-described embodiment. Is required to be stored as page identification information.

The terminal B receives the transmitted representative page, and
Print with. On the terminal B side, the operator looks at the printed representative page, knows the outline of each page, and determines whether or not there is a page in which a necessary image is described from among the images of the plurality of pages described in the representative page. Confirm. If there is a required image, the operator uses the keypad 4 and the LCD 1 to select a page on which the required image is described. Here, the selection operation in the case where the images of pages 1 and 3 of the representative page shown in FIG.
Explanation will be given according to the input screen diagram shown in FIG.

First, the operator inputs a page selection operation using the keypad 4, and causes the terminal B to enter the page selection mode. When proceeding to the page selection mode, as shown in FIG.
A list of destination addresses is displayed on the LCD 1 based on the reception result information, and the operator inputs a number indicating an address, which is call identification information of the terminal A, through the keypad 4. In this case, the "1" key has been input.

Next, a page selection instruction message is displayed on LCD1, and the operator selects a required page. The information to be input includes the number of the representative page on which the required image is described and the required page number in the representative page.
As shown in Figure 10, the representative page number “1”, page number “1”,
"3" is entered.

By such an operation, the input of the call identification information of the terminal A and the page identification information of the page describing the required image are performed.

Next, a communication processing procedure at this time will be described. FIG. 11 is a flowchart for explaining a communication processing procedure, and FIG. 12 is a diagram for exchanging commands and responses of each layer of a communication protocol between terminals in a normal procedure. First, the terminal B connects the line with the terminal A as shown in FIGS. 12 (a) to 12 (c) according to the input call identification information (steps # 101 and # 102).
Then, as shown in FIG. 12 (d), the terminal B transmits CSS indicating the start of the session in the session layer (refer to CCITT Recommendation T.62 “Control procedure for telex and group 4 facsimile services”) (step # 103). . Upon receiving the CSS (Step # 104), the terminal A determines whether or not the terminal itself has a non-standard terminal function, that is, a page selection transmission function (Step # 105). Transmit (step # 106), and if there is no such function, transmit the RSSN (step # 107). Terminal B
Determines the response from terminal A (step # 10).
8) If the response is the RSSN, that is, if the terminal A does not have the page selection transmission function, disconnect the line and end the communication (steps # 109 and # 110). Then, as shown in FIG. 13, a message indicating that the terminal A does not have the page selection transmission function is displayed on the LCD 1 or printed on the printer 5 to notify the operator (step # 111), and the processing is terminated.

On the other hand, if the response from terminal A is RSSP,
As shown in FIG. 7E, a CSCC for reversing the transmission and reception of the session is transmitted (step # 112). Terminal A is CSCC
Is received (step # 113), a document page selection command CDPS, which is a request command for the selected page as shown in FIG. 12 (f), is transmitted to terminal B (step # 114). Terminal B receives the CDPS (step # 11).
5) Then, the response information RDPS is added with the identification information of the selected page and transmitted (step # 116).

FIG. 15 is a diagram showing an example of encoding of various commands, parameter descriptors, parameter values, and page identification information. FIG. 15 (a) shows a document page selection command CD.
PS and its response RDPS are shown. In this example, the command and the response have different LSBs. Also the first
FIG. 5 (b) shows a parameter descriptor, FIG. 15 (c) shows a parameter value, and FIG. 15 (d) shows an example of page identification information using the parameter descriptor. Sent to terminal A together with RDPS.

When terminal A receives the RDPS (step # 117), RDPS
It is checked whether there is a page selected from the page identification information added to the URL and the page identification information of the transmission document stored in the work memory 15 (step # 118). If the selected page does not exist , CSCC without sending documents
Is transmitted (step # 119) to notify terminal B that the selected page does not exist. When the selected page exists, a document composed of the selected page is created as shown in FIGS. 12 (g) and 12 (h), CDCL and CDS are transmitted, and the document is transmitted as a normal document. Transmission is performed according to the procedure (step # 102). And after sending the document,
The CSCC is transmitted as shown in FIGS. 12 (i) and 12 (j) (step # 121).

On the other hand, if the terminal B receives the CSCC next after transmitting the RDPS, it determines that the selected page does not exist in the terminal A (step # 122), transmits RSCCP, and reverses the transmission / reception relationship. , Indicating the end of the session between the terminals A and B, C
Exchange SE and RSEP (Steps # 123 to # 12)
8), disconnect the line and end the communication (step # 129,
# 130). At this time, a message indicating that the selected page does not exist at the terminal A is transmitted to the terminal A as shown in FIG.
The operator is notified by displaying it on D1 or printing it on the printer 5 (step # 131).

If you do not receive CSCC and receive CDCL or CDS,
It is determined that the selected page exists in the terminal A, and reception is performed by a normal document reception procedure (step # 13).
2). After the document reception is completed, the CSCC is received (step # 133), and the reception of the document is confirmed. Next, FIG. 12 (j)
RSCCP is transmitted (steps # 134 and # 135) as shown in (1), the transmission and reception relations are inverted, and CSE and RSEP indicating the end of the session between both terminals A and B are transmitted as shown in FIG. Exchange is performed (steps # 136 to # 139), and FIG.
As shown in (m), the line is disconnected and the communication is terminated (steps # 140 and # 141).

With the above operation and communication procedure, it is possible to select a required page from the received representative page and perform communication and printing of only the required page.

〔effect〕

As described above, in the present invention, when transmitting a document composed of a plurality of pages, an image is transmitted by transmitting only a representative page indicating the outline of the document without transmitting and printing all pages, and printing the representative page. When data is easily checked and intuitively understood, the required page can be selected from the representative page, only the required page can be transmitted and printed, and all pages are transmitted and printed Communication and printing costs are reduced without performing unnecessary transmission and printing.

In particular, when performing communication of a full-color image having a large amount of image information and high printing cost, the present invention is particularly effective, and communication and printing costs can be reduced.
