Description

  The present invention relates to a facsimile apparatus and a facsimile transmission control method, and more specifically, a large-size document exceeding the reception capability of the reception side is divided and transmitted at the same magnification, and the reception side has good image quality without division or reduction. The present invention relates to a facsimile apparatus for transmitting image data and a facsimile transmission control method.

  Conventionally, when a facsimile unit transmits an image of an original with a scanner unit in facsimile transmission, if the original size is larger than the maximum transmittable size of facsimile transmission, the facsimile is divided into the maximum transmittable size, and the original is read and transmitted by facsimile. To do.

  In this case, when the document is read, the transmitting facsimile machine divides the image of the document into the maximum transmittable size by performing a division process on the length in the main scanning direction, and transmits the document. For example, for a large document of A2 / B3 size, the length (transmission width) in the main scanning direction is the maximum transmittable size when the original is read by the transmission facsimile machine. Then, the image is divided in the sub-scanning direction so that the original is read, and A3 / B4 size image data is transmitted (see Patent Document 1, Patent Document 2, etc.).

  The receiving facsimile machine records and outputs the received image data for one page on one sheet of recording paper. Therefore, when image data that is longer in the sub-scanning direction than image data that can be recorded on the recording paper is received, conventionally, the facsimile apparatus divides the received image data and outputs it on the recording paper. The long part is cut off and recorded.

  However, in the above prior art, when reading a document, the document size is determined based on the length in the main scanning direction, and the image in the sub-scanning direction is divided into lengths corresponding to the document size. Since the divided image is read and transmitted, the transmitted image may be longer than the length of the standard size recording paper in the sub-scanning direction. In such a case, the image is set on the receiving side. Depending on the size of the recording paper being used, the receiving side may need to further divide the received image and then print it out on the recording paper. There is a problem that the image quality deteriorates due to the necessity to reduce the image recording on the side.

Therefore, in the present invention, when it is determined that the length of the original document read by the scanner of the facsimile apparatus in the main scanning direction and the sub-scanning direction exceeds the receivable document width of the transmission destination, And the scanner is controlled to divide and read the original reading area so that the reading area in the sub-scanning direction is within the receivable original width of the transmission destination, By adopting a configuration in which a division number indicating a combination position when combining divided image data is added to each boundary portion of the sub-scan divided image data, a large-size original can be processed according to the reception capability on the reception side.

  As the scanner (image data input means) 2, for example, an image scanner using a CCD (Charge Coupled Device) or the like is used, and generally includes an ADF (Automatic Document Feeder). A plurality of documents are set in the ADF, and the ADF feeds the set documents one by one to the document reading position of the scanner 2. The scanner 2 scans the document conveyed from the ADF, divides the image of the document into pixels with a predetermined resolution, and converts each pixel into a monochrome image signal. In particular, the scanner 2 has a function of reading a large-size document whose document width in the main scanning direction exceeds the maximum size width (A3 size width) that can be received by the counterpart (reception side) facsimile apparatus acquired by the facsimile communication protocol. And a division reading function for reading the document by dividing it into a plurality of divided areas in the main scanning direction and the sub-scanning direction, and in the divided reading function, the boundary portions adjacent to each other in the divided areas are predetermined. Is provided with a superposition reading function for superposing and reading only the superposition width. The scanner 2 is equipped with a main scanning direction width size detection sensor that detects at least the width size of the set document in the main scanning direction, and outputs the detection result to the system control unit 7.

  The plotter 3 uses, for example, an electrophotographic recording apparatus, and records and outputs received image data and an image of a document read by the scanner 2 on a recording sheet.

  The encoding / decoding unit 4 is for increasing the efficiency of storing image data in the image storage unit 5 and shortening the transmission time. The encoding / decoding unit 4 encodes image data according to a predetermined encoding method, Decode the encoded image information.

  The image storage unit 5 is composed of, for example, a hard disk, a RAM (Random Access Memory), or the like, and in order to perform image editing such as rotation and reduction on the image read by the scanner 2, the document once read by the scanner 2 is stored. Save image data and received image data.

  The image rotation unit 6 replaces all the image data in the main scanning direction and the sub-scanning direction of the image data stored in the image storage unit 5 to rotate the image by 90 degrees, 270 degrees, or the like. Then, the rotated image data is stored in the image storage unit 5 again. Here, the rotation angle is 90 degrees or 270 degrees.

  The system control unit 7 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and in the ROM, a basic processing program of the facsimile apparatus 1 and an image division transmission control process described later. In addition to storing various programs such as programs, various data and system data necessary for executing the various programs such as the image division transmission control processing program and the basic processing program are stored. Based on a program in the ROM, the system control unit 7 uses the RAM as a work memory to control each unit of the facsimile apparatus 1 and executes basic processing as the facsimile apparatus 1 and also performs image division transmission control described later. Execute the process.

  The operation display unit 8 includes various operation keys such as a numeric keypad, a start key, and a function key, and also includes a display (for example, a liquid crystal display) 8a.

In FIG. 8 and FIG. 9, the contents of commands input from the operation keys and various information notified from the facsimile apparatus 1 to the operator are displayed. In particular, the operation display unit 8 is provided with a divided transmission on / off key for setting on / off of a divided transmission function for dividing, reading, and transmitting a transmission original.

  The division / magnification control unit 9 determines whether the main scanning direction of the image data read by the scanner 2 is larger than the maximum width A3 size that can be communicated on the facsimile communication protocol. If the width of the document (length in the main scanning direction) exceeds the maximum communicable width (A3 size width), it is determined whether the read page is to be divided. The original image is divided and read, and when the read page is not a division target, the original page image is read at the same magnification. Further, the division / magnification control unit 9 receives the identification information sent from the transmission destination by the facsimile communication protocol, for example, the main scanning direction and the sub scanning direction of the document read by the scanner 2 from the reception capability of the destination based on the NSF signal. Whether the scanning direction is within the receivable document width and receivable document length on the receiving side, or whether the image data obtained by rotating the divided image data is within the receivable document width and receivable document length on the receiving side Based on the above, it is determined whether or not the same size transmission is possible. The division / magnification control unit 9 causes the scanner 2 to read the original as usual when the equal magnification transmission is possible, and causes the scanner 2 to perform division reading when the equal magnification transmission is impossible.

  The communication control unit 10 is connected to a modem 11, and the modem 11 is connected to the network control unit 12. A line L, for example, a public telephone line, is connected to the network control unit 12, and the network control unit 12 operates under the control of the communication control unit 10 to perform processing as an interface with the line L, that is, An automatic call processing for a call from the line L and an automatic call process to the line L are performed.

  The modem 11 modulates a transmission signal such as a protocol signal and image information and demodulates a reception signal input via the network control unit 12 based on a facsimile communication standard or detects DTMF (Dual Tone Multifrequency). .

  The communication control unit 10 performs cadence detection control or exchanges a facsimile control signal with a partner facsimile machine to execute a facsimile communication procedure.

  As shown in FIG. 2, the facsimile apparatus 1 has a basic frame conforming to a high-level data link control procedure (HDLC) defined by ISO, as shown in FIG. It consists of a preamble for obtaining the binary information and the binary information following the preamble. The binary information includes a flag sequence (F), an address field (A), a control field (C), a facsimile control field (FCF), a facsimile control field (FIF), a frame check sequence (FCS), and a flag sequence (F). Has been. The facsimile information field (FIF) is an additional 8-bit unit information for further clarifying the facsimile procedure after the facsimile information field (FCF). This information is stored in the facsimile information field shown in FIG. It is defined by information of DIS, DCS, DTC, CSI, CIG, TSI, NSC, NSF and NSS signals shown in the communication transmission phase.

  In the transmission phase of facsimile communication, as shown in FIG. 3, the steps from the call origination to the disconnection of the facsimile communication are classified into phase A to phase E. In particular, phase B is a stage in which identification of functions between facsimile terminals, setting of a selected function, confirmation of reception status, etc. are performed. The only frame having a facsimile information field improves transmission efficiency and reliability. This is the stage to determine the improvement.

  Then, the facsimile machine 1 determines the receiving capability of the receiving facsimile machine based on the NSF signal.

  Next, the operation of this embodiment will be described. The facsimile apparatus 1 according to the present embodiment transmits an original image read by the scanner 2 by facsimile according to the facsimile communication procedure shown in FIG. If the document is read by the scanner 2, it is divided within the maximum reception width, and the image data of the document is read by performing overlay reading, and the read image data is rotated by 90 degrees or 270 degrees. And send it by facsimile.

  That is, as shown in FIG. 4, the facsimile apparatus 1 sets a document on the scanner 2, performs necessary operations such as a transmission destination and reading conditions on the operation display unit 8, and receives a start key for instructing the start of processing. When pressed, before the scanner 2 starts reading an image of the document, the width size of the document to be read on the scanner 2 in the main scanning direction is detected, and the width of the detected document in the main scanning direction (main scanning direction). It is checked whether the (scanning width) size exceeds the maximum size width that can be received by the facsimile apparatus acquired from the facsimile apparatus by the facsimile communication protocol, that is, the original width that can be transmitted to the other party at the same magnification (step S101). ).

  In step S101, when the main scanning width size of the document does not exceed the maximum size width in the main scanning direction that can be received by the counterpart facsimile apparatus (hereinafter referred to as the maximum receiving width if necessary), the facsimile apparatus 1 It is determined that it is not necessary to perform divided reading, the scanner 2 reads the original at the same magnification, performs the necessary image processing and encoding processing on the image data of the read original, transmits by facsimile, and ends the processing. (Step S102).

  In step S101, if the main scanning width size of the document is larger than the maximum reception width, the facsimile apparatus 1 checks whether the divided transmission function is on (step S103). The size of the original image is read by the scanner 2 without being divided, and the image of one page of the read original is reduced to a size that can be received by the receiving facsimile machine. Then, the reduced image data is encoded, Facsimile transmission is performed, and the process ends (step S104).

  If the split transmission function is ON in step S103, the facsimile apparatus 1 sets the reading sub-scanning width of the scanner 2 to ½ of the reading sub-scanning width of the document (step S105), and the set reading sub-scanning is performed. It is checked whether the width (sub-scan divided data width) is smaller than the maximum reception width (step S106).

  If the reading sub-scanning width is larger than the maximum receiving width in step S106, the reading main scanning width of the scanner 2 is set to ½ of the reading main scanning width of the document (step S107), and the set reading main scanning width is set. It is checked whether (main scanning division data width) is smaller than the maximum reception width (step S108).

  If the reading main scanning width is larger than the maximum receiving width in step S108, the facsimile apparatus 1 determines that it is not yet divided into width sizes that can be transmitted, returns to step S105, and performs the same as described above from the sub-scanning direction. The reading width is divided (steps S105 to S108), and when the reading scanning width is equal to or smaller than the maximum receiving width in at least one of the sub-scanning direction and the main scanning direction, the scanner 2 overlaps the boundary width of the divided reading area. The original is divided and read separately (step S109).

  That is, for example, as shown in FIG. 5, in the case of an A1 size document, it is divided into two in the sub-scanning direction and divided into two in the main scanning direction, and the reading first surface, the reading second surface, the reading third surface, and the reading Reading is performed in the order of the fourth surface. At this time, the overlapping width portion shown as the overlapping width in FIG. 5 is provided at the boundary portion of the divided reading region, and each reading surface is read in a state where the overlapping width is overlapped. .

  Then, when the facsimile apparatus 1 divides and reads a large-size document in this way, the divided image data is combined with each divided image data as indicated by a circled number in FIG. Is added to each divided image data.

  When the facsimile apparatus 1 performs division reading and adds a division number, the facsimile apparatus 1 checks whether the image data is rotationally symmetric (step S110). If the facsimile apparatus 1 is rotationally symmetric, the image data is rotated 90 degrees or 270 degrees, Necessary encoding processing or the like is performed, and facsimile transmission is performed to the other party (step S111).

  If the divided image data is not rotationally symmetric in step S110, the facsimile apparatus 1 performs necessary encoding processing and the like without rotating the divided image, and transmits the facsimile to the other party (step S111).

  In the facsimile communication, the facsimile apparatus 1 performs communication management information of the facsimile communication, that is, communication date and time of various communication files such as a transmission file, a reception file, and a standby file, a communication partner, a communication mode, success / failure of communication, and the like. The results are sequentially stored in the memory as communication management information. If necessary, the communication management information is displayed on the display (display means) 8a of the operation display unit 8 of the facsimile apparatus 1 or recorded as a communication management report on a recording sheet. In the divided communication, the communication management information is acquired and displayed on the display 8a or output as a communication management report. That is, the facsimile apparatus 1 acquires, as one piece of communication management information, whether or not the facsimile communication is divided transmission and stores it in a memory. For the divided transmission, as shown in FIG. When 20 is output, the fact that it is divided transmission is specified. In the communication management report 20 of FIG. 7, a symbol “B” indicating that the transmission is divided transmission is clearly shown in the transmission communication management information. Further, when the facsimile apparatus 1 displays the communication management information on the display 8a of the operation display unit 8, as shown in FIG. 8, the facsimile apparatus 1 clearly indicates the symbol “B” indicating that it is divided transmission.

  Note that the facsimile apparatus 1 of the present embodiment can set whether or not to attach a delivery slip by key operation of the operation display unit 8 when a large-size original is divided and transmitted.

  That is, usually when sending a facsimile document, a sending slip is pasted and sent, but since this sending slip is different in size from a large size manuscript, to send a sending slip properly, Since the control is different, the facsimile apparatus 1 allows the user to set whether or not to attach a delivery slip by key operation of the operation display unit 8.

  Specifically, as shown in FIG. 9, the facsimile apparatus 1 displays a screen for selecting whether or not to attach a delivery slip on the display 8 a of the operation display unit 8, and is turned ON / OFF by a key operation of the operation display unit 8. The underline (underbar) displayed at the bottom of is moved and selected according to whether or not the delivery slip is pasted.

  In other words, the facsimile apparatus 1 has a division target page selection function for subjecting to division transmission only for pages designated on the operation display unit 8 among the originals set on the scanner 2, and a page such as a delivery slip. When the operation display unit 8 designates a page without the page as a division target page, division transmission processing is performed based on the designation.

  In the above description, the facsimile apparatus 1 describes the case where the input image data is read by the scanner 2 and input. However, when the facsimile apparatus 1 is connected to the network, the input image data is It may be input from a scanner or a computer connected to the network. In this case, the input image data is temporarily stored in the image storage unit 5, and when the image data is read from the image storage unit 5, the division / same size control unit 9 reads and divides the image. It is possible to cope with it.

  As described above, the facsimile apparatus 1 according to the present embodiment inputs image data acquired by performing main scanning and sub-scanning on a document or / and image data sent from an external terminal as input image data, and sets a predetermined relationship with a destination. When the facsimile transmission protocol is exchanged and the input image data is encoded by a predetermined encoding method and then transmitted by facsimile, the input is performed based on the identification information sent from the other party by the facsimile communication protocol. If it is determined whether the line data in the main scanning direction of the image data is within a document width that can be transmitted to the destination at the same magnification, and it is determined that the input image data cannot be transmitted to the destination at the same magnification. Sub-scan by dividing the input image data in the sub-scanning direction to the document width that can be transmitted to the destination by the facsimile communication protocol for each data. If it is determined that the input image data can be transmitted to the other party at the same magnification, the sub-scan divided data that has been taken in is encoded after being rotated 90 degrees or 270 degrees and then encoded and transmitted to the other party. The input image data is captured as it is, and the captured image data is encoded and transmitted to the destination.

  Therefore, it is possible to perform transmission by performing division processing on the length in the sub-scanning direction of a large-size document in accordance with the reception capability on the reception side, and image quality without performing division printing or reduction printing on the reception side. Can be transmitted at the same magnification.

  Further, the facsimile apparatus 1 of this embodiment uses an NSF signal as identification information sent from the other party.

  Therefore, it is possible to perform the same size transmission of a large-size document only in the case of communication in the original mode, and in communication with a conventional model or another manufacturer, normal transmission / reception can be performed to improve usability.

  Furthermore, when the input image data is divided in the sub-scanning direction, the facsimile apparatus 1 according to the present embodiment divides the divided image data with a predetermined overlapping width in the boundary area between the divided images.

  Therefore, when image data near the center of the document where image information such as characters is likely to be collected is divided and read, even a small amount of image data can be prevented from being discarded due to errors in division processing. Therefore, it is possible to transmit an image with better image quality.

  Further, when the input image data is composed of a plurality of pages, the facsimile apparatus 1 according to the present embodiment captures divided data for an arbitrary preset page.

  Therefore, only large-size documents that have both large and small sizes are sent, such as when sending a small-size delivery slip that does not need to be split into the first page and sent together with a large-size document. Can be divided and transmitted, the image quality can be improved and the usability can be improved.

  Furthermore, in the facsimile apparatus 1 of the present embodiment, the main scanning direction of the sub-scan divided data is within the document length that can be transmitted to the destination at the same magnification based on the identification information sent from the destination by the facsimile communication protocol. If it is determined that it is impossible to transmit the sub-scan divided data to the other party at the same magnification, the sub-scan divided data is divided in the main scanning direction, and the divided images are separated from each other in the boundary region. If it is determined that it is possible to transmit the sub-scan divided data to the other party at the same magnification, the sub-scan divided data is captured as it is, and the captured image data is encoded and encoded. Sending to the other party.

  Therefore, even a larger-sized document, for example, a large-sized document having a maximum A0 size can be divided and transmitted without performing reduction processing, and the image can be transmitted without performing divided printing or reduced printing on the receiving side. It is possible to transmit an equal-sized image with good quality.

  Further, the facsimile apparatus 1 according to the present embodiment adds a predetermined composite symbol indicating a composite position between the divided data to the divided sub-scan divided data or sub-scan divided data and main scan divided data.

  Therefore, when the divided image transmitted after being divided is restored on the receiving side, it can be restored appropriately and easily based on the composite symbol, and the usability can be further improved.

The invention made by the present inventor has been specifically described based on the preferred embodiments. However, the present invention is not limited to the above, and various modifications can be made without departing from the scope of the invention. Needless to say. That is, the following can be mentioned about the example of a change about the structure of this invention, and its effect | action.
Input image data obtained by main scanning and sub-scanning of an original or / and image data sent from an external terminal as input image data, exchange a predetermined facsimile communication protocol with the partner, and input image data When the facsimile is transmitted after being encoded with a predetermined encoding method, the line data in the main scanning direction of the input image data is converted to the destination based on the identification information sent from the destination by the facsimile communication protocol. If it is determined that the input image data cannot be transmitted to the other party at the same size, the facsimile communication protocol is used for each data. The input image data is divided in the sub-scanning direction into the transmissible document width and is taken in as sub-scan divided data. When the divided data is rotated 90 degrees or 270 degrees and then encoded and transmitted to the other party. When it is determined that the input image data can be transmitted to the other party at the same magnification, the input image data is captured as it is. Since the image data is encoded and transmitted to the destination, it can be transmitted by performing division processing on the length of the large-size document in the sub-scanning direction according to the reception capability of the reception side. An equal-size image with good image quality can be transmitted without performing division printing or reduced printing.
In addition, since the NSF signal is used as identification information sent from the other party, it is possible to send a large-size original at the same magnification only in the case of communication in the original mode, and in communication with conventional models and other manufacturers. Can improve usability by performing normal transmission and reception. Further, when the input image data is divided in the sub-scanning direction, it is divided by giving a predetermined overlap width to the boundary area between the divided images of the divided image data, so that image information such as characters is likely to be gathered. When the image data near the center of the document is divided and read, it is possible to prevent even a small amount of image data from being discarded due to an error in the dividing process, and it is possible to transmit an image having a better image quality. it can. In addition, when the input image data is composed of multiple pages, the divided data is taken in to any preset page, so a small-size delivery slip that does not require division processing is used as the first page. As in the case of inserting and transmitting together with a large document, only a large size can be divided and transmitted with respect to a document of a mixture of large and small sizes, and image quality can be improved. , Can improve usability.
Further, based on the identification information sent from the other party by the facsimile communication protocol, it is determined whether or not the main scanning direction of the sub-scan divided data is within the document length that can be transmitted to the other party at the same magnification. If the sub-scan divided data is determined to be unable to be transmitted at the same magnification, the sub-scan divided data is divided in the main scanning direction, and the boundary area between the divided images is given a predetermined overlap width. If it is determined that it is possible to transmit the sub-scan divided data to the partner at the same magnification, the sub-scan divided data is captured as it is, and the captured image data is encoded and transmitted to the partner. A document of a size, for example, a large document of a maximum A0 size can be divided and transmitted without performing a reduction process. It can be transmitted without the image quality good magnification images can. Further, since a predetermined composite symbol indicating a composite position between the respective divided data is added to the divided sub-scan divided data or the sub-scan divided data and the main scan divided data, the divided image to be transmitted after being divided Can be restored appropriately and easily based on the composite symbol, and the usability can be further improved. Furthermore, when the image data is divided and transmitted, the divided transmission history information is acquired, the divided transmission history information is recorded and output as a communication management report, and the divided transmission history information is displayed on the display means. As a result, it is possible to make a list of history information related to the same size / division for each transmission destination, and it is easy to grasp information related to the reception capability of the other party, thereby further improving the usability. be able to.
Also, input image data obtained by main scanning and sub-scanning of the document or / and image data sent from an external terminal as input image data, exchange a predetermined facsimile communication protocol with the other party, and input the data When facsimile transmission is performed after the image data is encoded by a predetermined encoding method, line data in the main scanning direction of the input image data is determined based on the identification information transmitted from the other party by the facsimile communication protocol. It is determined whether or not the document width is within a document width that can be transmitted to the other party, and if it is determined that the input image data cannot be transmitted to the other party at the same magnification, the corresponding communication partner uses the facsimile communication protocol for each data. The input image data is divided in the sub-scanning direction into the document width that can be transmitted first, and is taken in as sub-scan divided data. After the sub-scan divided data is rotated by 90 degrees or 270 degrees and then encoded and transmitted to the destination, if it is determined that the same size transmission of the input image data is possible, the input image data is taken as it is, Since the captured image data is encoded and transmitted to the destination, it can be transmitted after being divided into the length in the sub-scanning direction of a large-size document according to the reception capability of the receiving side. The same-size image with good image quality can be transmitted without performing division printing or reduced printing on the side.

  The present invention can be applied to a facsimile machine that appropriately divides a large-size document and transmits it.
