  Hereinafter, the processing method will be further described. FIG. 6 is a diagram illustrating the entire processing flow of the printing system according to the first embodiment.

  First, the booklet data acquisition unit 51 acquires the booklet data stored in the storage unit 12 or the like (step S101). The processing content is as described above.

  Next, the page set detection unit 52 and the booklet print data output unit 53 obtain the number of booklets based on the booklet data (step S102). FIG. 7 is a flowchart showing details of the process (step S102) for obtaining the number of booklets in the printing system according to the first embodiment. The page set detection unit 52 obtains the number N of booklet sheets from the booklet data (step S201). The number of sheets N is obtained by dividing the number of pages of the booklet indicated by the booklet data by four. In the present embodiment, 2N or (2N + 1), which is the page number of a set of pages printed on the same surface of the same sheet, can be detected from the number N of sheets of the booklet. In the following processing, the processing is described using only the number N of sheets without using the page numbers of the pages constituting the page group. If each of the page image data 62 corresponds to one page, the number of pages N is obtained by dividing the number of page image data 62 by four. Next, the separate print data output unit 53 acquires the maximum number of processed sheets S of the post-processing apparatus (step S202). The maximum processing number S may be acquired from the post-processing device 3 via the communication unit 13 and the network 4, or may be read out from the storage unit 12 of the document processing device 1 in advance.

  Next, the separate print data output unit 53 divides the sheets 61 constituting the booklet into the maximum number of processed sheets S as the number of booklets that is the sum of the numbers of the intermediate booklet, the front partial booklet, and the rear partial booklet. Find the minimum odd number greater than or equal to (number of provisional booklets). First, a quotient m obtained by dividing N by S and a remainder r are obtained (step S203). Here, if r is not 0 (Y in step S204), even if it is divided for each maximum number of processed sheets S, (m + 1) booklets are required, so the number of temporary booklets is set to m + 1 (step S205). . If r is 0 (N in step S204), the number of provisional booklets is set to m (step S206) because it is divided into m booklets when divided for each maximum number of processed sheets S.

  Next, the separate print data output unit 53 obtains the minimum odd number equal to or greater than the number of temporary booklets as the number of booklets v. The reason for setting the minimum odd number is that the number of the front partial booklet and the number of the rear partial booklet need to be equal when the minimum number of booklets is used. When separating the pages so that blank pages do not occur in the intermediate booklet, the middle page is included so that the number of pages in the first half of the intermediate booklet is equal to the number of pages in the second half, including the middle two pages of the original booklet. Allocate to the sheets that make up the booklet. Then, since the number of pages allocated to the front partial booklet is equal to the number of pages allocated to the rear partial booklet, the number of front partial booklets and the number of rear partial booklets are also equal. Then, the sum of the number of the front partial booklet and the number of the rear partial booklet becomes an even number, and if 1 which is the number of the intermediate booklet is added thereto, the number of the booklet becomes an odd number. Looking at the details of the process, if the number of temporary booklets is an odd number (Y in step S207), the number of booklets v is the number of temporary booklets (step S208), and if the number of temporary booklets is an even number (N in step S207). The number of booklets v is (number of temporary booklets + 1) (step S209). The number v of booklets is obtained by the processing so far.

  Following step S102, the separate print data output unit 53 obtains the number of sheets of the intermediate booklet (step S103). FIG. 8 is a flowchart showing details of the process (step S103) for obtaining the number of sheets of the intermediate booklet in the printing system according to the first embodiment. The separate print data output unit 53 first obtains a quotient a and a remainder b obtained by dividing the number N of booklets by the number v of separate booklets (step S301). Next, the order c of the intermediate booklet, in other words, what number booklet the intermediate booklet becomes is obtained (step S302). The rank c is obtained by dividing (v + 1) by 2.

  Next, the separate print data output unit 53 sets the number x (c) of sheets in the intermediate booklet so that the number of the remaining sheets 61 after assigning the sheets 61 to the intermediate booklet is an even number. Here, x (k) indicates the number of sheets of the kth booklet when ranking is given through the front partial booklet, the intermediate booklet, and the rear partial booklet. In this way, the number of pages assigned to any of the previous partial booklets is equal to the number of pages assigned to any of the rear partial booklets, and each of the intermediate booklet, the front partial booklet, and the booklet is configured. The number of pages allocated to the sheet to be processed is a multiple of four. In the present embodiment, x (k) is either a or a + 1.

  A detailed method for obtaining x (c) is shown below. First, when the sheet number N is an odd number (Y in step S303), if a is an odd number (Y in step S304), x (c) is set to a (step S305), and if a is an even number (step S304). N) x (c) is set to a + 1 (step S306). When the sheet number N is an even number (N in Step S303), if a is an odd number (Y in Step S307), x (c) is set to a + 1 (Step S308), and if a is an even number (Step S307). N) Let x (c) be a (step S309).

  Following step S103, the separate print data output unit 53 obtains the number of sheets of the front partial booklet and the rear partial booklet (step S104). FIG. 9 is a flowchart showing details of processing for obtaining the number of sheets of the front partial booklet and the rear partial booklet in the printing system according to the first embodiment. The separate print data output unit 53 obtains the number d of the front partial booklets where the number of sheets is a + 1 (the number of the rear partial booklets is also d) (step S401). d is obtained by the calculation of b / 2 when x (c) is a, and is obtained by the calculation of (b-1) / 2 when x (c) is a + 1. Then, the number of sheets x (i) of each of the front partial booklet and the rear partial booklet (i is an integer between 1 and v excluding c) is obtained (step S402). Specifically, the number of sheets of each front partial booklet is such that the number of sheets of d of the (v-1) / 2 front partial booklets is a + 1 and the number of sheets of the remaining front partial booklet is a. Similarly, the number of sheets in each rear partial booklet is such that the number of sheets of d in the (v-1) / 2 rear partial booklets is a + 1 and the number of sheets in the remaining rear partial booklets is a. Set. The specific number of sheets is, for example, x (i) = a + 1 in a booklet that satisfies 1 ≦ i ≦ d or v−d + 1 ≦ i ≦ v, and a portion that satisfies d + 1 ≦ i <c or c <i ≦ v−d. In the booklet, x (i) = a may be set.

  Following step S104, the separate print data output unit 53 generates and outputs a separate print data (step S105). Since the number of sheets of each booklet has already been obtained, in this embodiment, four times the number of sheets x (i) is assigned to the i-th booklet in order from the first page of the booklet page. The corresponding page image data 62 is assigned to the corresponding one of the front partial booklet data, intermediate booklet data, and rear partial booklet data.

  After step S105, the printing unit 54 prints the sheets constituting each of the front partial booklet, the intermediate booklet, and the rear partial booklet, and the post-processing unit 55 overlaps the printed sheets for each booklet and folds them. (Step S106).

  By performing these processes, a front partial booklet, an intermediate partial booklet, and a rear partial booklet obtained by dividing the booklet are created. FIG. 10 is a diagram schematically illustrating a page configuration of a booklet separated based on booklet data with 7 sheets. Here, the maximum processing number S is three. By the processing described so far, the number of booklets is an odd number of 3, and the number of sheets of the intermediate booklet is an odd number. Thereby, the number of sheets allocated to the front partial booklet and the rear partial booklet (number obtained by subtracting the number of sheets of the intermediate booklet from the number of sheets of the original booklet) is an even number. The number of sheets can also be seen from FIG. Since the number of pages allocated to each sheet is 4, the number of pages separated by broken lines among the pages of each booklet separated by solid lines is the number of sheets.

  FIG. 11 is a diagram illustrating an example of booklet data having 8 sheets. Here, the maximum processing number S is three. By the processing described so far, the number of booklets is an odd number of 3, and the number of sheets of the intermediate booklet is an even number. Thereby, the number of sheets allocated to the front partial booklet and the rear partial booklet (number obtained by subtracting the number of sheets of the intermediate booklet from the number of sheets of the original booklet) is an even number.

  FIG. 13 is a diagram illustrating an example of the booklet data of the booklet illustrated in FIG. FIG. 13 is a diagram corresponding to FIG. 5 in the first embodiment. In this example, the set of pages is a set of 10 pages and 23 pages. In the present embodiment, a set of pages is determined based on the relationship between the page numbers of pages on which the region corresponding to the end on the crease side is drawn. FIG. 14 is a diagram showing a page on which an image is drawn in the first area or the second area. This figure shows a set of pages of pages 10 and 23, which are pages constituting the valley-side surface of the fourth sheet counting from the foremost sheet 61 in a state of being folded in two. Since it is described over two pages, the end close to the crease in the original sheet 61, that is, the right end of the page image indicated by the page image data 62 of the 10th page and the left side of the page image indicated by the page image data 62 of the 23rd page An image is drawn at the edge of. Here, the first area 67 is an area corresponding to the right end (first end) of the page image indicated by the page image data 62. In the case of the present embodiment, the first area 67 is an area having a certain width (for example, 5 mm) from the right edge of the rectangular page image. The second area 68 is an area corresponding to the left end (second end opposite to the first end) of the page image indicated by the page image data 62. In the present embodiment, the second area 68 is an area having a certain width (for example, 5 mm) from the left end side of the rectangular page image. A specific page set detection method will be described later.

  An example of the configuration of the printing system according to the present embodiment is the same as that illustrated in FIG. 3 in the description of the first embodiment. Also, the functional block configuration of the functions realized by the printing system is the same as that shown in FIG. 4 in the description of the first embodiment.

  The processing method in this embodiment will be described below. In addition to the process of FIG. 6 described in the first embodiment, the overall image of the process flow is between the process of obtaining the number of booklets (step S102) and the process of obtaining the number of sheets of the intermediate booklet (step S103). The difference is that there is a process for detecting a set of pages. Also, the processing contents of the processing for obtaining the number of sheets of the intermediate booklet (step S103) and the processing for obtaining the number of sheets of the front partial booklet and the rear partial booklet (step S104) are different from the first embodiment.

  The processing content of the processing for detecting a page set will be described. FIG. 15 is a diagram showing the configuration of the page set detection unit 52 in the second embodiment. The page set detection unit 52 includes a first detection unit 57 and a second detection unit 58. The page set detection unit 52 corresponds to a set of pages printed on the same surface of the same sheet 61 in the booklet based on the detection results of the page image data 62 of the first detection unit 57 and the second detection unit 58. A page image data set 63 is detected. Here, the first detection unit 57 detects the first page image data 62 in which an image is drawn in the first region corresponding to the first edge of the page from the booklet data. The second detection unit 58 obtains second page image data 62 in which an image is drawn in a second region corresponding to the second end of the page opposite to the first end of the page from the booklet data. To detect.

  The first detection unit 57 detects the page image data 62 of the page on which the image is drawn in the first area 67 from each page image data 62. As a detection method, a determination is made based on the amount of lines detected in the first region 67. As a method for detecting a line, for example, there is a method using edge detection. For example, when edge detection is performed on the first area 67 of the page image data 62 in which a rectangular frame line is provided at the corner of the image drawing area 66, the image is drawn in the first area 67 on 10 pages, for example. Edge detection is performed on a frame line or the like. A 1st detection part extracts the line extended in a horizontal direction among the lines by which edge detection was carried out. When a line extending in the horizontal direction is extracted, in the case of left-opening or right-opening, a horizontal line corresponding to the above-described frame line across the spread is detected, and a page number or a margin symbol is not detected. Here, since the line extending in the horizontal direction may be deviated by a certain angle due to a reading error of a scanner or the like, the angle of the line to be extracted may be given a width in advance. The first detection unit 57 determines whether or not the amount of the line extending in the horizontal direction detected from the first area 67 for each page image data 62 is higher than a certain threshold value. 62 page numbers are stored in the storage unit 12. Specific examples of the amount of lines include the total length of lines and the number of lines.

  The second detection unit 58 detects the page image data 62 of the page on which the image is drawn in the second area 68 from each page image data 62. As a detection method, a determination is made based on the amount of lines detected in the second region 68. The line detection method and the like are the same as those of the first detection unit 57.

  Then, the page set detection unit 52 acquires a page number that is larger than 2N + 1 and odd, among the page numbers of the page image data 62 in which an image is drawn in the first area 67, and stores the page number Pr as a storage unit. 12 to save. The page set detection unit 52 acquires a page number that is smaller than 2N and is an even number among the page numbers of the page image data 62 in which an image is drawn in the second area 68, and stores the page number Pl in the storage unit 12. save. Then, the page set detection unit 52 reads the page number Pr and the page number Pl from the storage unit 12, and determines the number of pages between the page number Pl and the first half of the first page, and between the page number Pr and the first half of the second half. The page number Pr and the page number Pl that have the same number of pages are detected. More specifically, a set of page number Pr and page number Pl in which Pr + Pl is 4N + 1 is detected.

  Note that this is the case of a left-opened printed material that rolls pages from right to left, and in the case of a right-opened printed material that rolls pages from left to right, the left-right relationship between the first area and the second area is switched. .

  Next, the process (step S103) for obtaining the number of sheets of the intermediate booklet will be described. FIG. 16 is a flowchart showing details of processing for obtaining the number of sheets of the intermediate booklet in the printing system according to the second embodiment. The separate print data output unit 53 first obtains a quotient a and a remainder b obtained by dividing the number N of booklets by the number v of separate booklets (step S3101). Next, the order c of the intermediate booklet, in other words, what number booklet the intermediate booklet becomes is obtained (step S3102). The rank c is obtained by dividing (v + 1) by 2.

  Next, the separate print data output unit 53 obtains the minimum number of sheets a1 required to include a set of pages in the intermediate booklet (step S3103). The sheet number a1 can be obtained by calculating (Pr−Pl + 1) / 4. When the sheet number a1 is smaller than the maximum processing sheet number S and larger than a, the temporary sheet number ac of the intermediate booklet is set to a1. Specifically, if the sheet number a1 satisfies the relationship of a <a1 ≦ S (Y in step S3104), the temporary sheet number ac of the intermediate booklet is set to a1 (step S3105), and the relationship of a <a1 ≦ S. Is not satisfied (N in step S3104), the temporary sheet number ac of the intermediate booklet is set to a (step S3106).

  Next, the separate print data output unit 53 sets the number x (c) of sheets in the intermediate booklet so that the number of the remaining sheets 61 after assigning the sheets 61 to the intermediate booklet is an even number. A detailed method for obtaining x (c) is shown below. First, when the sheet number N is an odd number (Y in step S3107), if ac is an odd number (Y in step S3108), x (c) is set to ac (step S3109), and if ac is an even number (step S3108). N) x (c) is set to ac + 1 (step S3110). When the number N of sheets is an even number (N in step S3107), if ac is an odd number (Y in step S3111), x (c) is set to ac + 1 (step S3112), and if ac is an even number (in step S3111). N) x (c) is set to ac (step S3113).

  Following step S103, the separate print data output unit 53 obtains the number of sheets of the front partial booklet and the rear partial booklet (step S104). FIG. 17 is a flowchart showing details of processing for obtaining the number of sheets of the front partial booklet and the rear partial booklet in the printing system according to the second embodiment. The separate print data output unit 53 obtains the number N1 of sheets assigned to the front partial booklet and the rear partial booklet (step S4101). The number of sheets N1 is obtained by calculating Nx (c). Next, the separate print data output unit 53 obtains a quotient e and a remainder f obtained by dividing N1 by (v-1) (step S4102). The separate print data output unit 53 obtains the number g of the front partial booklet (the number of the rear partial booklet is also g) where the number of sheets is e + 1 (step S4103). g is obtained by calculating f / 2. Then, the number of sheets x (i) of each of the front partial booklet and the rear partial booklet (i is an integer between 1 and v excluding c) is obtained (step S4104). Specifically, the number of sheets of each front partial booklet is such that the number of sheets of g in the (v-1) / 2 front partial booklet is e + 1 and the number of sheets of the remaining front partial booklet is e. Similarly, (v-1) / 2 sheets of the rear partial booklet so that the number of g sheets in the rear partial booklet is e + 1 and the number of sheets of the remaining rear partial booklet is e. Set the number.

  By performing these processes, a front partial booklet, an intermediate partial booklet, and a rear partial booklet obtained by dividing the booklet are created. In the example of FIG. 13, when the maximum number of processed sheets S is 3, the number of booklets is an odd number of 3 and the number of sheets of the intermediate booklet is an even number by the processing described so far. Thereby, the number of sheets allocated to the front partial booklet and the rear partial booklet (number obtained by subtracting the number of sheets of the intermediate booklet from the number of sheets of the original booklet) is an even number. Further, the quotient “a” obtained by dividing the number of sheets 8 by S is 2, but the number of sheets in the intermediate booklet is 4, which includes a set of pages.

  Although several embodiments have been described so far, the present invention is not limited to this. For example, a blank page may be provided in each booklet. Further, if it is not necessary to minimize the number of booklets, the number of the front partial booklet and the rear partial booklet may be divided into any number as long as the number of sheets is within the maximum processing sheet number S. The number of booklets and the number of back partial booklets may be different.
