Abstract

PROBLEM TO BE SOLVED: To record a desired part unmagnified on a receiving side even in the case of contract-recording image information on the receiving side since the length of image information exceeds that of a routine size by divide- recording received image information in plural recording papers of the routine size. SOLUTION: When (La+Lc).Smin+Lb is larger than Lmax, wherein La shows a length expressed in terms of the number of lines outside of a range, Lc shows a length expressed in terms of the number of lines outside of a range, Smin shows a lower limit reduction percentage previously set in RAM, Lb shows a length expressed in terms of the number of lines in an unmagnified range and Lmax shows the length of a routine size expressed in terms of the number of lines, since one page of received image information can not be recorded in the recording paper of the routine size of one page, the received information is divide-recorded. This unmagnified range Lb is set by a transmission side that desires it to be looked as a clear image. Then, the image information is divided outside of this range Lb and recorded in the recording paper of the routine size as plural pages of image information to avoid the lange Lb from being divided.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a facsimile apparatus.

[0002]

2. Description of the Related Art In a facsimile apparatus, if a G3 facsimile is taken as an example, the width of image information to be transmitted and received is A4.
(Width 215 mm: 1728 pixels), B4 (width 255 mm: 2)
048 pixels), A4 (width 303 mm: 2432 pixels), and the like.

However, the length of image information to be transmitted and received is A
It does not always match the length of the standard size such as 4, B4, A3. That is, even if a document with a fixed width and a longer length is read on the transmission side, or a document with a fixed width and a longer length is read, the length of the document is reduced due to slippage of the sub-scanning mechanism. This is because it is read as image information longer than the length of the standard size.

If the receiving-side plotter records the received image information on roll paper, it can be recorded as one page of image information even if the length of the received image information exceeds the length of the standard size.

On the other hand, if the receiving-side plotter records the received image information on a standard cut sheet such as an electrophotographic system, if the length of the received image information exceeds the length of the standard size,
Since the excess image information cannot be discarded, the excess image information is recorded on the second page of recording paper. However, when the length of the received image information exceeds the length of the standard size, the length of the recording paper on the second page is almost blank, which is wasteful.

Therefore, an allowable amount of the length of the portion exceeding the standard size of the length of the received image information is set in advance, and if the allowable amount is exceeded, the received image information is divided into a plurality of pages. If the amount does not exceed the allowable amount, the length direction of the received image information is reduced so that the length of the received image information is recorded so as to be within the standard size corresponding to the width of the received image information. This prevents waste of recording paper.

[0007]

However, if image information longer than the length of the standard size is reduced and recorded on the receiving side, the image quality is deteriorated as compared with the image information transmitted from the transmitting side. As a result, image information, such as catalog information, which should be received and recorded at the same magnification as the original, including parts that you want to see as beautiful images, is also reduced and recorded on the receiving side regardless of the intention of the user on the transmitting side. Would.

[0008] In view of this, there has been proposed a technique in which, on the receiving side, received image information is reduced and recorded and then re-outputted at the same magnification to obtain clear image information, as in the technique described in Japanese Patent Application Laid-Open No. 5-328104. However, in this case, re-outputting causes waste of recording paper.

The present invention has been made in view of the above circumstances, and even when the length of image information exceeds the length of the standard size and is reduced and recorded on the receiving side, the desired portion of the transmitting side is magnified. It is an object of the present invention to provide a facsimile apparatus which can be recorded by using a facsimile apparatus.

[0010]

According to a first aspect of the present invention, there is provided a facsimile apparatus in which a receiving side receives transmission image information from a transmission side, and has a fixed size corresponding to a width of the reception image information. While recording received image information on recording paper,
When the length of the received image information exceeds the length of the standard size corresponding to the width of the received image information by a predetermined amount or more, the received image information is divided and recorded on a plurality of sheets of the standard size, and When the amount of the length exceeding the length of the fixed size corresponding to the width of the received image information is equal to or less than the predetermined amount, the length of the received image information is reduced at the reduction rate that becomes the length of the fixed size. In a facsimile apparatus that reduces the size in the length direction and records the fixed-size recording paper, the transmitting side uses a same-size range setting unit that sets a same-size range in the transmission image information, and the same-size range setting unit. The set equal-size range, and a partial equal-size transmission unit that notifies the receiving side of the fact that the transmission image information includes the same-size range is attached to the transmission image information. The received image information is in the same size range In the case of notification of the inclusion and the same-size range, the sum of the length of the portion outside the same-size range in the received image information reduced by the predetermined lower limit reduction ratio and the length of the same-size range is the received image size. When the length is less than or equal to the length of the fixed size corresponding to the width of the information, the length of the portion outside the equal size range in the received image information is the length obtained by subtracting the length of the equal size range from the length of the fixed size. Shrink in the length direction at a shrinkage ratio that almost matches
The length of the portion of the received image information outside the equal-size range reduced at a predetermined lower limit reduction ratio while being linked to the image information of the same-size range and recorded on one sheet of the standard size recording paper. When the sum of the length of the same-size range is equal to or greater than the length of the fixed size corresponding to the width of the received image information, the partial equal-size recording means for dividing and recording the received image information on a plurality of fixed-size recording papers And characterized in that:

According to a second aspect of the present invention, in the facsimile apparatus according to the first aspect of the present invention, the partial equal-size recording means includes means for identifying an equal-magnification range in the received image information as being outside the equal-magnification range. It is characterized in that double range identification information is embedded in the received image information and recorded.

A facsimile apparatus according to a third aspect of the present invention is the facsimile apparatus according to the second aspect, wherein the same-size range identification information for identifying the same-size range in the received image information as being outside the same-size range is received. An identification information addition setting unit configured to set whether or not to record by embedding the information in the information; and the partial equal-size recording unit embeds the same-size range identification information in the received image information by the identification information addition setting unit. Only when the setting for recording is made, the same-size range identification information is recorded by being embedded in the received image information.

A facsimile apparatus according to a fourth aspect of the present invention is the facsimile apparatus according to any one of the first, second, and third aspects, wherein the partial equal-magnification recording means is configured to delete a part of the received image information outside the equal-magnification range. When the sum of the length obtained by reducing the length at the predetermined lower limit reduction rate and the length of the same size range is equal to or greater than the length of the fixed size corresponding to the width of the received image information, the same size range is not divided. The received image information is divided and recorded on a plurality of recording sheets.

FIG. 7, FIG. 8, and FIG. 9 show a specific processing procedure of the processing for transmitting the partial original in the processing 114.

In these figures, the system control unit 2
Displays the display D20 shown in FIG. 10 on the display 9h,
The user is prompted to specify the start position of the unit size range in mm units (process 20).
1) Display a numeric string input by the numeric keypad 9a D2
While performing an input process of sequentially displaying 0 and storing the input numeric string (process 202), the [Yes] key 9b
Is pressed (No loop of judgment 203).

When the [Yes] key 9b is depressed (Yes in the judgment 203), the display 9h further displays FIG.

When the [Yes] key 9b is depressed (Yes in decision 203), a line number conversion is performed based on the input start position of the unity-magnification range in mm and the currently set reading line density. The unit-size range start position ls is calculated (process 207). More specifically, the start position of the unity-magnification range in mm units input in the process 202 is 75 mm, and the currently set reading linear density is “normal: 3.75 l / mm”.
Then, the line size conversion equal-size range start position ls is 7
It can be calculated as 5 × 3.75 = 281 (rounded down below the decimal point).

From the input unit-magnification range length in mm, the currently set reading linear density, and the unit-magnification range start position ls calculated in the process 207, the line-conversion-type unit-magnification range end position is obtained. le is calculated (process 208). Specifically, the unit-size range start position ls calculated in the process 207 is 281, the unit-size range length in mm units input in the process 205 is 100 mm, and the currently set reading linear density is “normal character”. : 3.75 l / mm ”, the line number conversion equal-size range start position ls is 100 × 3.75 + 28

As a result, the value of the pixel P1 in each line becomes 1
If so, it can be determined that the line belongs to the equal-magnification range, and if it is 0, it belongs to the outside of the equal-magnification range.

After the processing 213 or 212, the l-th
The r-line is encoded and compressed by the encoding / decoding unit 8 and stored in the image memory (process 214), and the variable lr is incremented (process 215) to determine whether reading of one page of the document has been completed (determination). 216) If not completed (No in decision 216), the process returns to step 210. When the process is completed (Yes in decision 216), it is determined whether a document of the next page to be read by the scanner 5 is set (decision 217), and when there is a next page (Y in decision 217).
es), and return to the process 209. If there is no next page (No in decision 217), a call is made to the destination specified in decision 104 in FIG. 4 (process 218), and a call is made to the receiving side apparatus connected to the line based on the G3 facsimile protocol. A pre-transmission procedure is performed to set communication parameters such as the width of transmission image information and modem speed (process 219). In the pre-transmission procedure of the process 219, the non-standard function identification signal NSF
In response to the fact that the receiving side is provided with the partial equal-size recording function according to the present invention by the predetermined bits of the information field, the predetermined bit of the non-standard function setting signal NSS determines the image information to be transmitted from now on. Notify that it includes the area to be recorded at the same magnification.

Then, in step 214, the image information including the same-size range sequentially stored in the image memory 7 is transmitted to the receiving side (step 220), a post-transmission procedure is performed (step 221), and the processing is terminated.

The information for specifying the equal magnification range in the transmission (reception) image information is transmitted from the transmission side to the reception side as the value of the pixel P1 of each line of the image information transmitted in the process 220. Will be. Of course, it is also possible to embed the same-size range in the image information in the information field of the non-standard function setting signal NSS to notify the receiving side.

The image information including the same size range transmitted from the transmitting side to the receiving side in this way is recorded on the recording paper by the receiving side.

FIG. 12 shows the correspondence between the line density of image information and the length in terms of the number of lines in accordance with the size.

In the figure, a standard size A4 at a linear density of “3.85 l / mm” corresponding to “normal”
(Length 297mm) is the total length Lmax in terms of the number of lines.
1143 lines, standard size B4 (total length 364m)
The total length Lmax in terms of the number of lines in m) is 1401 lines. Also, the linear density “7.7” corresponding to “small characters”

The total length Lmax in terms of the number of lines in m) is 2286 lines, and the total length Lmax in terms of the number of lines of the standard size B4 (total length of 364 mm) is 2802 lines.

FIG. 13 shows the structure of the transmission / reception image information including the same magnification range and the outside of the range. In the figure, the transmission / reception image information includes an equal-magnification range Lb from an equal-magnification range start position ls to an equal-magnification range end position le, and a length (ls)
-1) is constituted by La outside the front range and Lc outside the rear range.

Next, the facsimile machine 1 as a receiving side
Will be described.

First, a procedure for setting the same size range mark addition will be described with reference to FIG.

In the figure, the system control unit 2 monitors whether or not the [Function] key 9f is pressed and the number "50" is input by the numeric keypad 9a to activate the 1: 1 range mark addition setting mode. If the same magnification range mark addition setting mode is activated (Yes in decision 301), a display D30 shown in FIG. 15 is displayed on the display 9h, and the same magnification range mark is displayed. Whether or not to add is selected by pressing the [←] key 9gl or [→] key 9gr, and the user is prompted to press the [Yes] key 9b (process 302).

Each time the user presses the [←] key 9gl or the [→] key 9gr, the display D30 is displayed.
In (3), the cursor is moved to the character string “add” or “not added”, and cursor control for storing the current cursor position is performed (process 303).

loop). When the [Yes] key 9b is pressed (judgment 3
04, Yes), the current cursor position is determined (determination 3).
05) If "add", set the same size range mark flag Fm stored in the RAM 4 to 1 (process 306), and if "not add", set the flag Fm to 0. It is reset (process 307).

As a result, it is possible to set whether or not to add the same size range mark as the value of the flag Fm.

Next, a procedure of a facsimile receiving process in the facsimile apparatus 1 will be described with reference to FIG.

In the figure, the system control unit 2 monitors whether an incoming call is detected by the network control unit 11 (No loop of judgment 401), and when an incoming call is detected (judgment 4).
01, Yes), G between the transmitting side apparatus connected to the line
A pre-transmission procedure based on the 3 facsimile protocol is performed, and communication parameters such as the width of received image information and a modem speed are set (process 402). Note that, in the pre-transmission procedure of the process 402, the transmission side is informed of the provision of the partial equal-size recording function according to the present invention by a predetermined bit of the information field of the non-standard function identification signal NSF. Then, a predetermined bit of the non-standard function setting signal NSS informs the transmitting side that the image information to be transmitted from now on includes a range to be recorded at the same magnification.

Then, the image information is received and stored in the image memory 7 (step 403), and the post-transmission procedure is performed (step 40).
4) After the communication is completed, in the pre-transmission procedure of process 402,
It is determined whether or not a notification of partial equal magnification has been received by the non-standard function setting signal NSS corresponding to the process 219 of FIG. 9 on the transmitting side (decision 405).
5 (Yes), the normal recording process is performed (process 406). This normal recording process corresponds if the total number of lines of the received image information for one page is shorter than the total length Lmax defined as shown in FIG. 12 by the line density and width of the received image information. While recording is directly performed on a single recording sheet of a standard size, if it is longer than the total length Lmax, the total length Lmax
If the amount exceeding the predetermined length is equal to or less than a predetermined amount (set in advance), the data is reduced in the length direction by line thinning processing or the like so as to be within the total length Lmax, and the amount exceeding the total length Lmax is equal to or larger than the predetermined amount. If there is, the process is to record the same size within the range of the full length Lmax on the recording paper of the first page and to record the portion exceeding the full length Lmax on the recording paper of the next page.

If a partial magnification is notified by the non-standard function setting signal NSS (Yes in decision 405), partial magnification recording processing is performed (processing 407).

FIGS. 17 and 18 show a specific processing procedure of the partial magnification recording processing of the processing 407. FIG.

In the figure, the system control unit 2 first substitutes an initial value 1 for a variable ld (process 501), and among the received image information stored in the image memory 7, the 1st Iran image information of the image information of the first page. Are read by the encoding / decoding unit 8 and sequentially expanded in the image memory 7 (process 502).

Then, the 1st line of the decoded 1st line
It is determined whether the value of the pixel P1 is 1 or not (0) if the value of the pixel P1 is 1 if the d-line is within the equal-magnification range and 0 if the d-line is outside the equal-magnification range (decision 503). If it is 0 (No in decision 503), the variable ld is incremented (process 504), and the process returns to process 502. As a result, the out-of-range La is decoded.

In the judgment 503, if the value of the pixel P1 is 1 (Yes in the judgment 503), the equal-magnification range Lb is set, and the current value of the variable ld is changed to the equal-magnification range start position l.
s (process 505), and if the value of the same-size range mark flag Fm is 0 and the setting is to not add the same-size range mark (Yes in decision 506), the pixel P on the ld-th line is set.
The value of 1 is set to 0 corresponding to a white pixel (process 507), and the process proceeds to process 508. In the case of setting to add the same size range mark (No in decision 506), the
The process proceeds to step 508 while maintaining the value of the pixel P1 on the d-line at 1 corresponding to the black pixel.

In process 508, the variable ld is incremented, the ld-th Iran is read from the image memory 7, decoded by the encoding / decoding section 8, and sequentially developed in the image memory 7 (process 509). Then, of the decoded ld-th line,
It is determined whether the value of the pixel P1 is 1 if the 1st line is within the equal-magnification range and 0 if the ld-th line is outside the equal-magnification range (determination 510), and the value of the pixel P1 is determined. Is 1 (No in decision 510), it is determined whether there is a next line in the received image information of the same page (decision 511). If there is a next line (Yes in decision 511), the process proceeds to step 508. Returning, if there is no next line (No in decision 511),
The current value of the variable ld is substituted for the same-size range end position le (process 512), and the flow shifts to decision 517.

If the value of the pixel P1 is 0 in the judgment 510 (Yes in the judgment 510), the value becomes Lc outside the range after this, and the value obtained by subtracting 1 from the current variable ld is set as the 1: 1 range end position le. The variable ld is incremented (process 515), and the ld-th Iran is read from the image memory 7 and decoded by the encoding / decoding unit 8 so that the next line is present (Yes in decision 514). 7 (step 516).

If there is no next line in judgment 514 (judgment 5
(No in 14), or when there is no next line in decision 511 (No in decision 511), that is, when decoding of the received image information for one page is completed, (La +
Lc) It is determined whether Smin + Lb is equal to or less than Lmax (determination 517).

Here, La is the value of processing 5 shown in FIG.
1 from the starting position ls of the same magnification range converted into the number of lines obtained in 05
Is the number of lines obtained by subtracting, and indicates the length in terms of the number of lines outside the previous range. Lc is calculated based on the current value of ld, that is, the total number of lines of the received image information for one page.
13 or the number of lines obtained by subtracting the line-converted equal-magnification range end position le obtained by the processing 512, and indicates the length of the number of lines outside the previous range. Smin is a lower limit reduction rate preset in the RAM 4 as shown in FIG. 2, and the length direction of the outside of the front range La and the outside of the rear range Lc is one page including an equal size range that is not reduced. In order to fit the image information of one minute on a standard recording paper of one page, it indicates the limit to prevent the image information from being reduced indefinitely.
For example, the contents of the out-of-range La and the out-of-range Lc after reduction are set to appropriate legible values such as 75%. Lb
Is a value obtained by adding 1 to a value obtained by subtracting the line size conversion equal magnification range start position ls obtained in the processing 505 from the line number conversion equal magnification range end position le obtained in the processing 513 or 512, The length of the line number conversion in the equal magnification range is shown. Lmax indicates the length of the fixed size in terms of the number of lines, defined by the relationship shown in FIG. 12 from the fixed width and the line density of the received image information for one page.

That is, (La + Lc) · Smin + L
Whether b is equal to or less than Lmax means that the image obtained by reducing the front outside range La and the rear outside range Lc in the length direction within the range of the set lower limit reduction ratio Smin and the equal magnification range Lb. This means whether the information can be recorded on a recording sheet of a standard size corresponding to the standard width of the received image information for one page without protruding in the length direction.

Therefore, if the judgment 517 is Yes, 1
La outside the front range and Lc outside the rear range of the received image information for the page
Is reduced to (Lmax−Lb) / (La + Lc) times (process 518). The reduction process can be easily performed by the line thinning process according to the reduction ratio. Then, the outside of the front range La and the outside of the rear range Lc after the reduction are connected to the same size range b in the original order, and are recorded as image information of one page by the plotter 6 on the recording paper of the corresponding fixed size. (Process 5
19).

If the decision 517 is No, the received image information for one page cannot be recorded on one page of fixed-size recording paper, and must be divided and recorded.
The same-magnification range Lb is set so that the transmission side wants to see the image as a clear image.
Is recorded on a fixed-size recording paper as image information for a plurality of pages so that the equal-magnification range Lb is not divided (step 520). If there is received image information of the next page to be recorded (Yes in decision 521),
Returning to the processing 501, the processing 501 is performed for the next page.
The following processing is performed, and if there is no next page (determination 52
(No in 1), the process ends.

FIG. 19 shows a case where the judgment 517 is Yes.
The correspondence between the received image information for a page and the image information recorded on a fixed size recording paper is shown. In FIG.
And Lc outside the rear range is (Lmax−Lb) / (La + L)
c) The image is reduced by a factor of 1, and the same-size range Lb is recorded with the same size (1 ×). As a result, the whole area Lc outside the front range and the outside area Lc outside the front range are reduced at the minimum reduction ratio necessary to fit the entire length Lmax of the standard size, and the same size range Lb
Is recorded at the same magnification without deteriorating the image quality.

In FIG. 20, when the judgment 517 is No, the same size range end position le is the full length Lmax of the standard size.
FIG. 6 shows the correspondence between the received image information for one page and the image information recorded on a fixed-size recording sheet when it is on the front side.
In the drawing, La outside the front range and the same size range Lb are the first range.
The same size recording is performed on the recording paper of the standard size of the page, and Lc outside the rear range is printed on the second page at the same size. for that reason,
The same size range Lb is not separately recorded on the first page and the second page.

In FIG. 21, when the judgment 517 is No, the same size range end position le is the full length Lmax of the standard size.
This shows the correspondence between the received image information for one page and the image information recorded on the recording paper of a fixed size when it is later. In the figure, suppose that La outside the front range and the same size range Lb are
When recording on the standard size recording paper of the first page, the rear end of the equal magnification range Lb must be divided and recorded on the second page. The same-magnification range Lb is recorded without division by recording the same-magnification range Lb on the second page and the rear-range Lc on the third page, respectively. Of course, the outside of the rear range Lc may be recorded on the second page following the equal-magnification range Lb, and the protruding portion may be recorded on the third page. Since it becomes necessary and does not save the recording paper, it is recorded on the third page so that Lc outside the rear range is not divided.

FIG. 22 shows that the equal magnification range mark flag Fm is 1
The same magnification range identification mark M added in the case of is shown. In the figure, the same-size range identification mark M is a pixel P1 of each line in the same-size range for identifying a line in the same-size range.
Is formed by recording the value 1 set to the black pixel as it is. The area to be recorded at the same magnification can be easily specified by the same magnification range identification mark M. Note that the pixel P having the value 1
If the 1: 1 range identification mark M is too thin with only 1,
The value of several pixels at the left end (or the right end) of the line where the value of the pixel P1 is 1 may be set to 1 so that the 1: 1 range identification mark M is recorded thick. Further, a mark indicating the start and end of the same-size range may be added to each of the same-size range start position ls and the same-size range end position le.

In the above-described embodiment, the present invention is applied to a G3 facsimile, but the present invention is not limited to this, and can be similarly applied to a facsimile apparatus based on another protocol. .
