Part 244.
The image processing program 20 sets information related to a double-sided printed original document in which an integrated image in which a plurality of page units are integrated is formed on one page by the above-described components.
Further, the image processing program 20 determines the order of page units divided into page units based on the set information, rearranges the page units based on the determined order, and the image reading device 140 aggregates them. Image data having each page unit as one page is generated from the read data obtained by reading the document.

Here, the collected original will be described.
An aggregated document is a document in which a plurality of pages in an original document (original document) are collected and printed on one sheet (recording medium), that is, one page, mainly to reduce the number of printed sheets.
Hereinafter, each of a plurality of pages aggregated on one page in the aggregated manuscript (that is, one constituting one page in the original manuscript before being aggregated) is referred to as a page unit. An image indicating a page unit is referred to as a page unit image.
Further, hereinafter, an image in which images indicating a plurality of page units are aggregated into one page is referred to as an aggregated image. In other words, the aggregated image includes a plurality of page unit images. The aggregated image is formed on one page of the aggregated document.

FIG. 3A illustrates an aggregate document in which two pages (page units) are aggregated on one sheet.
In this example, there are two pages in the original document, but each page is reduced, and these two page units are formed on a single sheet.
When the page unit orientations are vertically aligned from left to right (that is, when the first page and second page are arranged from left to right), the arrangement order of the page units (number of page units 2) In the case of).

The “direction of page unit” is the direction when the page unit is placed in a direction that can be read (recognized).
For example, “the orientation of the page unit is vertical” means that when the page unit is placed vertically (in other words, the long side of the page unit is oriented vertically and the short side is oriented horizontally), the page unit is read ( Recognize) It is possible orientation.
Also, for example, “the direction of the page unit is horizontal” means that the page unit is set to be horizontally long (in other words, the long side of the page unit is set horizontally and the short side is set vertically). It means that the orientation is legible (recognizable).

When the page unit orientations are horizontal and arranged side by side from top to bottom, the arrangement order of the page units is referred to as “forward vertical direction” (in the case of 2 page units).
When the page unit orientations are arranged vertically and arranged from right to left, the arrangement order of the page units is referred to as “reverse horizontal direction” (when the number of page units is 2).
When the page unit orientations are horizontal and arranged from bottom to top, the arrangement order of the page units is referred to as “reverse vertical direction” (in the case of 2 page units).

FIG. 3B illustrates an aggregate document in which four pages (page units) are aggregated on one sheet.
In this example, the original document has four pages. However, each page is reduced, and the unit of the four pages is formed on one sheet.
When the page units are arranged in the order of upper left, upper right, lower left, lower right (that is, when the first page, second page, third page, fourth page are arranged in the order of upper left, upper right, lower left, lower right) ), And the arrangement order of the page unit is referred to as “forward horizontal direction”.
When page units are arranged in the order of upper left, lower left, upper right, lower right (that is, arranged in the order of upper left, lower left, upper right, lower right, page 1, page 2, page 3, page 4) ), And the arrangement order of the page unit is referred to as “forward vertical direction”.
When page units are arranged in the order of upper right, upper left, lower right, lower left (ie, arranged in the order of upper right, upper left, lower right, lower left, first page, second page, third page, fourth page) ), The order of arrangement in page units is called “reverse horizontal direction”.
When page units are arranged in order of upper right, lower right, upper left, lower left (that is, arranged in the order of upper right, lower right, upper left, lower left, page 1, page 2, page 3, page 4) ), And the arrangement order of the page unit is called “reverse vertical direction”.

In the setting processing unit 210 (FIG. 2), the setting screen display unit 212 causes the UI device 130 to display a setting screen for setting information regarding the aggregated document.
FIG. 4 is a diagram illustrating a setting screen.
A setting screen illustrated in FIG. 4A is displayed on the UI device 130.
The setting screen displays buttons for setting the number of divisions, the arrangement order, the page unit orientation, whether or not double-sided printing is performed, and the binding position.
Here, the number of divisions is a number that is divided when an image is divided into page units from the aggregated image, and is the number of page units included in one sheet.
The binding position is a position where the paper is bound in the case of duplex printing, and is referred to as “long-side binding” when the long side is bound, and “short-side binding” when the short side is bound.

The user of the image processing apparatus 1 uses the setting screen displayed on the UI device 130 to set information regarding the aggregated document.
For example, an aggregated document in which two page units are aggregated on one sheet and the arrangement order is the forward / horizontal direction (“forward / horizontal direction” in FIG. 3A), Assume that the image data is obtained by dividing into page units.
At this time, on the setting screen illustrated in FIG. 4A, the user presses the button for the division number “2”, presses the button for the arrangement order “forward / horizontal direction”, and sets the page unit direction “vertical”. Button, press the “both sides” button, and press the binding position “long edge binding” button.

In addition, for example, in an aggregated manuscript in which four vertical page units are collected on one sheet and the arrangement order is the forward and horizontal direction (“forward direction” in “page unit direction: vertical” in FIG. 3B). Assume that image data is obtained by dividing a long-edge-bound double-sided printing original into pages.
At this time, on the setting screen illustrated in FIG. 4A, the user presses the button for the division number “4”, presses the button for the arrangement order “forward / horizontal direction”, and sets the page unit direction “vertical”. Button, press the “both sides” button, and press the binding position “long edge binding” button.
The buttons in the order of arrangement may be indicated by arrows.
When the button with the division number “2” is pressed, as illustrated in FIG. 4B, a button indicating the arrangement order with vertical or horizontal arrows may be displayed on the setting screen. The person may press the button of the right arrow in the case of the forward and horizontal direction.
Further, when the button with the division number “4” is pressed, as illustrated in FIG. 4C, a button whose arrangement order is indicated by a zigzag arrow may be displayed on the setting screen.
In addition, when the button with the division number “8” is pressed, as illustrated in FIG. 4D, a button whose arrangement order is indicated by a zigzag arrow may be displayed on the setting screen.

The setting reception unit 214 (FIG. 2) receives information (setting information) set by the user using the setting screen displayed on the UI device 130, and sends the information to the document reading processing unit 220 and the image data generation processing unit 230. Output.
The original reading processing unit 220 controls the image reading device 140 to read the aggregated original and generate read data.

FIG. 5 is a flowchart (S10) illustrating processing of the document reading processing unit 220 and the image reading device 140.
Note that some of the steps may not be provided, and the order of the steps can be changed as appropriate.
In step 100 (S100), the document reading processing unit 220 receives the division number N and the arrangement order.
In step 102 (S102), the image reading device 140 pulls in the first page of the aggregated document.

In step 104 (S104), the document reading processing unit 220 sets K to an initial value (K = 1).
Note that K is the order in which each page unit is arranged according to the arrangement order. For example, in the case of the forward and horizontal direction in the example of FIG. 3B, the upper left page unit is K = 1, The page unit is K = 2, the lower left page unit is K = 3, and the lower right page unit is K = 4.
In step 106 (S106), the document reading processing unit 220 controls the image reading device 140 to read the page unit corresponding to the set K value.
For example, when K is an initial value (K = 1), the image reading device 140 reads an area in which a page unit corresponding to K = 1 (the upper left page unit in the above example) is formed.
An area where each page unit is formed is referred to as a divided area.

In step 108 (S108), the image reading device 140 and the original reading processing unit 220 perform necessary image processing on the read data obtained in units of pages.
Specifically, the image reading device 140 and the document reading processing unit 220 perform shading correction, blank sheet removal (removing read data when a blank area is read), color conversion, ground color removal, and pictogram separation. , Enlargement processing in the main scanning direction, digital spatial filter processing, and gamma correction.

In step 110 (S110), the document reading processing unit 220 adds attribute information to the read data. The attribute information will be described later.
In step 112 (S112), the document reading processing unit 220 accumulates page-by-page reading data (page-by-page reading data).
In step 114 (S114), the document reading processing unit 220 determines whether K = N (number of divisions), that is, whether the page unit whose arrangement order is the last has been read (N and K are 1 or more). Integer).
If K = N, that is, if there is a page unit that has not yet been read in the pages of the aggregated document, the process proceeds to S116, and if K = N, the process proceeds to S118.

In step 116 (S116), the value of K is incremented by 1, and the process proceeds to S106.
In step 118 (S118), the document reading processing unit 220 determines whether or not the page drawn by the image reading device 140 is the last page of the consolidated document. If the page is not the last page, the process proceeds to S120. If it is the last page, the process is terminated.
In step 120 (S120), the image reading apparatus 140 pulls in the next page of the aggregated document, and proceeds to S104.

The read data acquisition unit 222 (FIG. 2) acquires the read data obtained by the above processing and outputs it to the page unit order determination unit 232 of the image data generation processing unit 230.
FIG. 6 is a diagram illustrating read data.
As shown in FIG. 6, the read data includes page unit read data # 1 to #M (M is an integer of 1 or more) corresponding to each page unit.
Each page-unit read data includes page-unit image data indicating a page-unit image and attribute information indicating attributes of the page-unit image data.

Further, the attribute information includes reading order information, aggregated document page information, aggregated document front / back information, and divided region position information.
The divided area position information indicates the position of the divided area where the corresponding page unit is arranged, and corresponds to the order corresponding to the arrangement order, for example.
For example, in the example of the arrangement order “forward / horizontal direction” in FIG. 3B, the divided region position information is “divided region position 1” in the page unit arranged at the upper left, and the page unit arranged at the lower right. Then, the divided region position information is “divided region position 4”.

The aggregated manuscript page information indicates pages in the aggregated manuscript where the corresponding page unit has been arranged.
The aggregated manuscript front / back information indicates whether the page in the aggregated manuscript in which the corresponding page unit is arranged was a front page or a back page.
Note that when the odd page is a front page and the even page is a back page, there is no need for the aggregated manuscript front / back information.

The reading order information is information indicating the order in which the corresponding page units are read in the entire aggregated document, and the reading order information of the page unit reading data #m (m is an integer from 1 to M) is “mth”. Is.
For example, in the page unit arranged in the “divided region position 1” of the first page of the aggregated document with the division number 4, the reading order information indicates “first”, and the second page of the aggregated document with the division number 4 In the page unit arranged at “divided region position 1”, the reading order information indicates “fifth”.
As will be described later, the reading order information may not represent the correct order in the original document (that is, the order of pages is changed).
Further, the page unit image data may indicate a page unit image that is upside down.

FIGS. 7 and 8 are diagrams for explaining the order change and the upside down of the page-unit read data.
FIG. 7 illustrates the case of the division number 2.
In the case of the arrangement order “forward horizontal direction” and the binding position “short edge binding”, the page unit of the first page of the original document is arranged on the left side (division region position 1) on the first page (front page) of the consolidated document. The page unit of the second page of the original document is arranged on the right side (division area position 2). Further, on the second page (back page) of the aggregated document, the page unit of the third page of the original document is arranged on the left side (division area position 1), and the fourth page of the original document is arranged on the right side (division area position 2). Page units are arranged.
At this time, on the second page (back page) of the consolidated original, the order of the page units is not changed, and the upper and lower sides of the page units are not inverted.
Therefore, in this case, for example, the page unit image data of the page unit read data # 1 indicates an image that is not inverted upside down in the page unit of the first page of the original document, and the page unit image of the page unit read data # 3. The data indicates an image that is not flipped up and down in page units of the third page of the original document.

On the other hand, in the arrangement order “forward horizontal direction” and binding position “long edge binding”, the page unit of the first page of the original document is on the left side (division region position 1) on the first page (front page) of the consolidated document. The page unit of the second page of the original document is arranged on the right side (division area position 2), but on the second page (back page) of the consolidated original, the original document is placed on the left side (division area position 1). The page unit of the fourth page is arranged upside down, and the page unit of the third page of the original document is arranged upside down on the right side (division area position 2).
At this time, on the second page (back page) of the aggregated document, the order of the page units is changed, and the upper and lower sides of the page units are inverted.
Therefore, in this case, for example, the page unit image data of the page unit read data # 1 indicates an image that is not inverted upside down in the page unit of the first page of the original document, but the page unit of the page unit read data # 3. The image data indicates an image that is flipped up and down in units of pages of the fourth page of the original document, and the page-unit image data of page unit read data # 4 is flipped up and down in units of pages of the third page of the original document. The image that is being displayed.

Similarly, in the case of the arrangement order “forward / vertical direction” and the binding position “long edge binding”, the first page (front page) of the aggregated document has a page unit of the first page of the original document on the upper side (division region position 1). And the page unit of the second page of the original document is arranged on the lower side (division area position 2). Further, on the second page (back page) of the aggregated document, the page unit of the third page of the original document is arranged on the upper side (division region position 1), and the fourth page of the original document is arranged on the lower side (division region position 2). Page units are arranged.
At this time, on the second page (back page) of the consolidated original, the order of the page units is not changed, and the upper and lower sides of the page units are not inverted.
Therefore, in this case, for example, the page unit image data of the page unit read data # 1 indicates an image that is not inverted upside down in the page unit of the first page of the original document, and the page unit image of the page unit read data # 3. The data indicates an image that is not flipped up and down in page units of the third page of the original document.

On the other hand, in the case of the arrangement order “forward vertical direction” and the binding position “short edge binding”, the page unit of the first page of the original document is on the upper side (division region position 1) on the first page (front page) of the consolidated document. The page unit of the second page of the original document is arranged on the lower side (divided region position 2), but the original document is placed on the upper side (divided region position 1) on the second page (back page) of the consolidated document. The page unit of the fourth page is arranged upside down, and the page unit of the third page of the original document is arranged upside down on the lower side (division region position 2).
At this time, on the second page (back page) of the aggregated document, the order of the page units is changed, and the upper and lower sides of the page units are inverted.
Therefore, in this case, for example, the page unit image data of the page unit read data # 1 indicates an image that is not inverted upside down in the page unit of the first page of the original document, but the page unit of the page unit read data # 3. The image data indicates an image that is flipped up and down in units of pages of the fourth page of the original document, and the page-unit image data of page unit read data # 4 is flipped up and down in units of pages of the third page of the original document. The image that is being displayed.

FIG. 8 illustrates a case where the number of divisions is four.
In the case of arrangement order “forward horizontal direction”, page unit orientation “vertical”, and binding position “long edge binding”, one page of the original document at the upper left (division region position 1) on the first page (front page) of the consolidated document A page unit of the second page of the original document is arranged at the upper right (division area position 2), and a page unit of the third page of the original document is arranged at the lower left (division area position 3). The page unit of the fourth page of the original document is arranged in the lower right (division area position 4).
In the second page (back page) of the aggregated document, the page unit of the fifth page of the original document is arranged at the upper left (division area position 1), and the sixth page of the original document is arranged at the upper right (division area position 2). The page unit is arranged, the page unit of the seventh page of the original document is arranged in the lower left (division area position 3), and the blank page is arranged in the lower right (division area position 4).
At this time, on the second page (back page) of the consolidated original, the order of the page units is not changed, and the upper and lower sides of the page units are not inverted.
Therefore, in this case, for example, the page unit image data of the page unit read data # 1 indicates an image that is not inverted upside down in the page unit of the first page of the original document, and the page unit image of the page unit read data # 5. The data indicates an image that is not flipped up and down in units of the fifth page of the original document.

On the other hand, in the case of the arrangement order “forward horizontal direction”, page unit orientation “vertical”, and binding position “short edge binding”, the first page (front page) of the consolidated original has the same arrangement as that of “long edge binding”. A page unit is arranged.
However, on the second page (back page) of the consolidated original, a blank page is arranged at the upper left (division area position 1), and the page unit of the seventh page of the original original is arranged at the upper right (division area position 2). The page unit of the sixth page of the original document is arranged at (division area position 3), and the page unit of the fifth page of the original document is arranged at the lower right (division area position 4).
At this time, on the second page (back page) of the aggregated document, the order of the page units is changed, and the upper and lower sides of the page units are inverted.
Accordingly, in this case, for example, the page unit image data of the page unit read data # 1 indicates an image that is not inverted upside down in the page unit of the first page of the original document, but the page unit of the page unit read data # 5. The image data indicates an image that is not flipped up and down in page units of the seventh page of the original document. Note that the blank sheet placed in the upper left (division area position 1) has been removed.

Similarly, in the case of arrangement order “forward horizontal direction”, page unit direction “horizontal”, and binding position “short edge binding”, the original document is located at the upper left (division area position 1) on the first page (front page) of the consolidated original. The page unit of the second page of the original document is arranged at the upper right (division region position 2), and the page unit of the third page of the original document is arranged at the lower left (division region position 3). The page unit of the fourth page of the original document is arranged at the lower right (division area position 4).
In the second page (back page) of the aggregated document, the page unit of the fifth page of the original document is arranged at the upper left (division area position 1), and the sixth page of the original document is arranged at the upper right (division area position 2). The page unit is arranged, the page unit of the seventh page of the original document is arranged in the lower left (division area position 3), and the blank page is arranged in the lower right (division area position 4).
At this time, on the second page (back page) of the consolidated original, the order of the page units is not changed, and the upper and lower sides of the page units are not inverted.
Therefore, in this case, for example, the page unit image data of the page unit read data # 1 indicates an image that is not inverted upside down in the page unit of the first page of the original document, and the page unit image of the page unit read data # 5. The data indicates an image that is not flipped up and down in units of the fifth page of the original document.

On the other hand, in the case of arrangement order “forward horizontal direction”, page unit direction “horizontal”, and binding position “long edge binding”, the same arrangement as in the case of “short edge binding” on the first page (front page) of the consolidated document A page unit is arranged.
However, on the second page (back page) of the consolidated original, a blank page is arranged at the upper left (division area position 1), and the page unit of the seventh page of the original original is arranged at the upper right (division area position 2). The page unit of the sixth page of the original document is arranged at (division area position 3), and the page unit of the fifth page of the original document is arranged at the lower right (division area position 4).
At this time, on the second page (back page) of the aggregated document, the order of the page units is changed, and the upper and lower sides of the page units are inverted.
Accordingly, in this case, for example, the page unit image data of the page unit read data # 1 indicates an image that is not inverted upside down in the page unit of the first page of the original document, but the page unit of the page unit read data # 5. The image data indicates an image that is not flipped up and down in page units of the seventh page of the original document. Note that the blank sheet placed in the upper left (division area position 1) has been removed.

The page unit order determination unit 232 (FIG. 2) uses the order determination table stored in the order determination table storage unit 234 to determine the order of the page unit read data included in the read data.
Note that the order determination table stored in the order determination table storage unit 234 can be appropriately modified by the administrator of the image processing apparatus 1 operating the UI device 130, for example.
The page unit rearrangement unit 236 rearranges the order of page unit read data in the order of page units in the original document (that is, the correct order) according to the order determined by the page unit order determination unit 232, and rearranges the read data. Is output to the upside down determination unit 238.

9 to 11 are diagrams illustrating the order determination table stored in the order determination table storage unit 234.
As illustrated in FIG. 9, the order determination table is provided for each number of divisions and arrangement order.
FIG. 10 exemplifies a “two-divided / forward-horizontal table” with the division number “2” and the arrangement order “forward-horizontal direction”.
In the 2-split / forward horizontal direction table, a page unit order input value is set for each divided region position according to the binding position and the front and back of the aggregated document.

Here, the page unit order input value is a value for rearranging the page units in the correct order.
For example, in the case of the binding position “long edge binding”, the page unit order input value “1” is set to the divided region position 1 and the page unit order input value “1” is set to the divided region position 2 on the front page of the aggregated document. 2 "is set.
On the back page of the aggregated document, the page unit order input value “2” is set in the divided region position 1, and the page unit order input value “1” is set in the divided region position 2.

FIG. 11 exemplifies a “4 division / forward horizontal direction table” with the division number “4” and the arrangement order “forward horizontal direction”.
In the 4-split / forward horizontal direction table, page unit order input values are assigned for each divided region position in accordance with the binding position, the page unit orientation, and the front and back of the aggregated document.
For example, when the binding position is “short edge binding” and the page unit orientation is “vertical”, the page unit order input value “1” is set to the divided area position 1 and the divided area position 2 is set to the front page of the aggregated document. The page unit order input value “2” is set, the page unit order input value “3” is set to the divided region position 3, and the page unit order input value “4” is set to the divided region position 4. .
Further, on the back page of the aggregated document, the page unit order input value “4” is set to the divided region position 1, the page unit order input value “3” is set to the divided region position 2, and the divided region position 3 is set. Is set to the page unit order input value “2”, and the divided region position 4 is set to the page unit order input value “1”.

FIG. 12 is a diagram for explaining a specific example of processing of the page unit order determination unit 232 and the page unit rearrangement unit 236.
In FIG. 12, in the aggregated document, the division number is “4”, the arrangement order is “forward / horizontal direction”, the binding position is “short edge binding”, the page unit direction is “vertical” (see FIG. 8), and the page unit number is “ The case of “23” is illustrated.
The page unit order determination unit 232 receives setting information indicating the number of divisions “4”, the arrangement order “forward horizontal direction”, the binding position “short edge binding”, and the page unit direction “vertical” from the setting reception unit 214.
Further, the page unit order determination unit 232 acquires an order determination table corresponding to the received setting information from the order determination table storage unit 234.
In the case of the above example, the page unit order determination unit 232 acquires a table of the binding position “short edge binding” and the page unit direction “vertical” of the “four division / forward horizontal direction table” (FIG. 11).
The page unit order determination unit 232 assigns a page unit order value to each page unit read data based on the following equation (1).
(1) [Page unit order value] = ([Aggregated manuscript page] -1) × (Number of divisions) + [Page unit order input value]

This will be specifically described below with reference to FIG.
First, the page unit order determination unit 232 extracts page unit read data # 1 from the read data.
In the attribute information (FIG. 6) of the page-unit read data # 1, the aggregated document page information indicates “first page”, the aggregated document front / back information indicates “front page”, and the divided region position information is “divided region position 1”. Is shown.
Since the page unit order input value of the divided region position 1 on the front page is “1”, the page unit order value of the page unit read data # 1 is (1-1) × 4 + 1 = 1.
Therefore, the page unit order determination unit 232 assigns a page unit order value “1” to the page unit read data # 1.
Similarly, the page unit order determination unit 232 takes out the page unit read data # 2 to # 4 and assigns page unit order values “2” to “4”, respectively.

Next, the page unit order determination unit 232 extracts page unit read data # 5 from the read data.
In the attribute information of the page-unit read data # 5, the aggregated document page information indicates “second page”, the aggregated document front / back information indicates “back page”, and the divided region position information indicates “divided region position 1”.
Since the page unit order input value of the divided region position 1 on the back page is “4”, the page unit order value of the page unit read data # 5 is (2-1) × 4 + 4 = 8.
Therefore, the page unit order determination unit 232 assigns the page unit order value “8” to the page unit read data # 5.

Next, the page unit order determination unit 232 extracts page unit read data # 6 from the read data.
In the attribute information of the page unit read data # 6, the aggregated manuscript page information indicates “second page”, the aggregated manuscript front / back information indicates “back page”, and the divided region position information indicates “divided region position 2”.
Since the page unit order input value of the divided region position 2 on the back page is “3”, the page unit order value of the page unit read data # 5 is (2-1) × 4 + 3 = 7.
Therefore, the page unit order determination unit 232 assigns the page unit order value “7” to the page unit read data # 6.

Similarly, the page unit order determination unit 232 takes out the page unit read data # 7 and # 8 and assigns page unit order values “6” and “5”, respectively.
Similarly, the page unit order determination unit 232 assigns page unit order values shown in FIG. 12 to the page unit read data # 9 to # 20.

Further, the page unit order determination unit 232 extracts the page unit read data # 21 from the read data.
In the attribute information of the page-unit read data # 21, the aggregated document page information indicates “sixth page”, the aggregated document front / back information indicates “back page”, and the divided region position information indicates “divided region position 2”.
Here, the reason why the divided area position information of the page unit read data # 21 is “divided area position 2” is that a blank page is arranged in the divided area position 1 and there is no page unit corresponding to the divided area position 1. Because.
Since the page unit order input value of the divided region position 2 on the back page is “3”, the page unit order value of the page unit read data # 21 is (6-1) × 4 + 3 = 23.
Therefore, the page unit order determination unit 232 assigns the page unit order value “23” to the page unit read data # 21.

Further, the page unit order determination unit 232 extracts page unit read data # 22 from the read data.
In the attribute information of the page-unit read data # 22, the aggregated document page information indicates “sixth page”, the aggregated document front / back information indicates “back page”, and the divided region position information indicates “divided region position 3”.
Since the page unit order input value of the divided region position 3 on the back page is “2”, the page unit order value of the page unit read data # 22 is (6-1) × 4 + 2 = 22.
Therefore, the page unit order determination unit 232 assigns the page unit order value “22” to the page unit read data # 22.

Finally, the page unit order determination unit 232 extracts page unit read data # 23 from the read data.
In the attribute information of the page unit read data # 23, the aggregated document page information indicates “sixth page”, the aggregated document front / back information indicates “back page”, and the divided region position information indicates “divided region position 4”.
Since the page unit order input value of the divided region position 4 on the back page is “1”, the page unit order value of the page unit read data # 23 is (6-1) × 4 + 1 = 21.
Therefore, the page unit order determination unit 232 assigns the page unit order value “21” to the page unit read data # 23.

The page unit rearrangement unit 236 rearranges the page unit read data # 1 to # 23 as shown in FIG.
Since page unit read data # 5, # 6, # 7, and # 8 are assigned page unit order values “8”, “7”, “6”, and “5”, respectively, page unit rearrangement is performed. The unit 236 rearranges the page-unit read data # 5, # 6, # 7, and # 8 into the eighth, seventh, sixth, and fifth, respectively.
Similarly, the page unit rearrangement unit 236 rearranges the order of the page unit read data # 13 to # 16 and # 21 to # 23.

The upside down determination unit 238 (FIG. 2) uses the inversion determination table stored in the inversion determination table storage unit 240 to determine page unit read data including page unit image data that needs to be upside down.
Note that the inversion determination table stored in the inversion determination table storage unit 240 can be appropriately modified by the administrator of the image processing apparatus 1 operating the UI device 130, for example.
The vertical flip unit 242 processes the page unit image data included in the page unit read data determined by the vertical flip determination unit 238 so that the vertical unit is inverted (that is, in the correct orientation).

FIG. 13 is a diagram illustrating an inversion determination table stored in the inversion determination table storage unit 240.
As illustrated in FIG. 13, the inversion determination table is provided for each division number, binding position, and page unit direction.
For example, when the number of divisions is “2”, the binding position is “long edge binding”, and the page unit orientation is “vertical”, the page unit arranged on the front page of the aggregated document does not require upside down processing. Upside down processing is necessary for the page unit arranged on the back page.
Further, for example, in the case of the division number “4”, the binding position “short edge binding”, and the page unit orientation “vertical”, the page unit arranged on the front page of the aggregated document does not require the upside down process, but the aggregation is performed. The page unit arranged on the back page of the document needs to be turned upside down.

In the example of FIG. 12, since the number of divisions is “4”, the binding position is “short edge binding”, and the page unit orientation is “vertical”, the page unit arranged on the back page of the aggregated document is Inversion processing is necessary.
Here, since the aggregate document back and front information of the page unit read data # 5 to # 8, # 13 to 16, and # 21 to # 23 indicates “back page”, the upside down unit 242 causes the page unit read data # 5 to # 5. Upside down processing is performed on the page unit image data included in # 8, # 13 to 16, and # 21 to # 23.

FIG. 14 is a diagram illustrating the flow of processing of the image data generation processing unit 230 in the example of FIG.
As shown in FIG. 14A, the original reading processing unit 220 reads each page unit from the aggregated original, and the read data shown in FIG. 14B is obtained.
Here, “1”, “2”, “3”, and “4” in FIG. 14B indicate the page unit image data of the page unit read data # 1 to # 4, respectively, and are “8” inverted upside down. ",""7","6", and "5" indicate page unit image data of page unit read data # 5 to # 8, respectively.
As described above, the page unit rearrangement unit 236 replaces the page unit read data # 5 to # 8 so that the page unit order is the same as that of the original document (that is, the correct order). Incorrect.
As described above, the upside down unit 242 performs the upside down process on the page unit image data of the page unit read data # 5 to # 8, so that they are arranged in the correct order as shown in FIG. A page unit with the correct orientation is generated.

The image data generation unit 244 (FIG. 2) performs processing such as removing attribute information included in the page-unit read data and assigning a new identifier (based on the correct order of page units).
Further, the image data generation unit 244 generates image data in which the page unit in the correct orientation is one page, and these page units are arranged in the correct order, and stores the image data in the image data storage unit 260.
The image formation processing unit 262 controls the printing apparatus 150 to perform processing for forming image data on a sheet (recording medium).

FIG. 16 is a diagram illustrating an order determination table and a reversal determination table in the case of a bound book.

As shown in FIG. 15A, in the case of a bound and bound document having a division number “8”, an arrangement order “forward / horizontal direction”, and a page unit direction “vertical”, a cut is made in a bold line part, and a broken line part is folded in a valley. When the one-dot chain line portion is folded in a mountain, a booklet having “1” to “8” as 1 to 8 pages is created.
Here, when the division number “8” is set on the setting screen displayed by the setting screen display unit 212, a “binding binding” setting button is displayed, and the user presses the button to bind the bound binding document. Is read, the read data including the page unit image data shown in FIG. 15B is obtained.
Here, “1”, “8”, “7”, and “6” that are vertically inverted in FIG. 15B indicate the page unit image data of the page unit read data # 1 to # 4, respectively, and “2”. ”,“ 3 ”,“ 4 ”, and“ 5 ”indicate page unit image data of page unit read data # 5 to # 8, respectively.

At this time, the divided region positions of the page-unit read data # 1 to # 8 are “divided region position 1” to “divided region position 8”, respectively.
The page unit order determining unit 232 refers to the table illustrated in FIG. 16 and inputs the page unit order input values “1”, “8”, “7”, “ “6”, “2”, “3”, “4”, “5” are assigned.
The page unit rearrangement unit 236 rearranges the page unit read data # 1 to # 8 according to the assigned page unit order input value.
The vertical inversion determination unit 238 needs to invert the page-unit read data # 1 to # 4 (“1”, “8”, “7”, “6”) with reference to the table illustrated in FIG. When it is determined that there is, the upside down unit 242 performs upside down processing on the page unit image data of the page unit read data # 1 to # 4.
With the above processing, page units with the correct orientation arranged in the correct order as shown in FIG. 15C are generated.
