[0022] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0023] In the field of image formation, many image forming devices already have an all-in-one imaging function, which can be used to automatically scale the contents of multiple pages and layout them into one page for printing. This function can save paper and meet the imaging needs of users in some special scenarios. In common technical solutions, the all-in-one types that image forming devices can support only include two-in-one type, four-in-one type, eight-in-one type and sixteen-in-one type. Understandably, refer to Figure 1 As shown in 1a, the two-in-one type is to layout the content of two pages into one page, refer to Figure 1 As shown in 1b, the four-in-one type is to typeset the contents of four pages into one page. Figure 1 As shown in 1c, the eight-in-one type is to typeset the contents of eight pages into one page. Figure 1 As shown in 1d, the sixteen-in-one type is to typeset the contents of sixteen pages into one page.

[0024] However, in actual application scenarios, users also hope to perform other all-in-one types of imaging, such as three-in-one type, five-in-one type, six-in-one type, etc., or split and reorganize the existing all-in-one type into user-defined all-in-one types. The existing technical solutions cannot meet the above-mentioned imaging needs of users.

[0025] This application is filed to address the above issues.

[0026] This application can be used to regenerate an all-in-one type of original into another all-in-one type of manuscript specified by the user, thereby meeting the user's imaging needs for a variety of different all-in-one types.

[0027] The technical solution provided in this application can be used for any image forming device, including but not limited to printers, copiers, fax machines, scanners, and multifunction machines that integrate printing, copying, faxing, scanning and other functions.

[0028] The technical solutions provided in this application are described in detail in the following examples.

[0029] Figure 2 The following is a flow chart of an image forming method provided in an embodiment of the present application. Figure 2 As shown, the storage process of print data may include: 101. Obtain original job parameters of the original page and target job parameters of the target page to be generated.

[0030] In the embodiment of the present application, the original page is any one or more pages in the all-in-one type manuscript that the user has printed, and the target page is another all-in-one type page that the user wants to generate. In the embodiment of the present application, for easy distinction, the all-in-one type information of the original page can be expressed as the original all-in-one type information, and the all-in-one type information of the target page can be expressed as the target all-in-one type information, and the original all-in-one type information is different from the target all-in-one type information. The image forming device can be used to convert the all-in-one type of the original page when the user has printed the original page of the all-in-one type, convert the original page into a target page of another all-in-one type, and print it.

[0031] Before implementing the all-in-one type conversion, the image forming device needs to first obtain the original job parameters of the original page and the target job parameters of the target page to be generated. Specifically, the panel of the image forming device may display the following: Figure 3 The target setting interface 30 shown in FIG. Figure 3 As shown, the target setting interface 30 is an all-in-one redefinition interface, which may include setting options for original job parameters of an original page and setting options for target job parameters of a target page to be generated.

[0032] Among them, the setting options for the original job parameters of the original page may include: scanning source 311, original imaging direction 312, original paper type 313, original all-in-one type 314, and original arrangement direction 315. In the embodiment of the present application, the "original" refers to the above-mentioned "original page". Specifically, the scanning source includes the manuscript table FB and the automatic document feeder (Automatic Document Feeder, ADF). When the scanning source is the manuscript table, the user places the documents to be scanned on the manuscript table page by page for scanning. When the scanning source is the ADF, the user places all the documents to be scanned into the ADF at one time, and the ADF automatically feeds them into the image forming device page by page for scanning, without the user manually placing them one by one. The original imaging direction refers to the direction in which the page content of the original is displayed on the page, such as Figure 4 As shown, for example Figure 4 The original image direction of a is upward. Figure 4 The original image direction of b is downward, Figure 4 The original image direction of c is left. Figure 4 d is in the right direction. The original paper type refers to the size of the original paper to be scanned, such as A4 paper type, A3 paper type, etc. The original arrangement direction refers to the arrangement direction of the original sub-images contained in the pages of the original, such as Figure 5 As shown, for example, it may include horizontal arrangement and vertical arrangement.

[0033] The setting options for the target job parameters of the target page to be generated may include: target paper type 321, target all-in-one type 322 and target arrangement direction 323. Among them, the target paper type refers to the paper type of the target page that the user wants to obtain. The target page is also the page that the user wants to obtain after scanning, reorganizing and copying the original page, that is, the "copy". The target arrangement direction refers to the arrangement direction of the target sub-images contained in the target page that the user wants to obtain. The target all-in-one type refers to the all-in-one type of the target page that the user wants to obtain. The value of the target all-in-one type can be obtained according to the user's input operation. Specifically, in response to the Figure 3 The trigger operation of the target all-in-one type 322 button in the interface shown in the figure can display the image forming device as shown in the figure. Figure 6 In the all-in-one redefinition interface shown in FIG. 1 , an input keyboard of a target all-in-one type 322 may be displayed in the all-in-one type redefinition interface, and a user may enter a customized all-in-one value in the input keyboard. For example, when the user desires to implement a three-in-one type of imaging, the user may enter a value of 3. In response to a triggering operation of a confirmation button in the input keyboard, the image forming apparatus may determine the target all-in-one type.

[0034] 102, obtaining a scanned image of the original page.

[0035] When the original job parameters of the original page and the target job parameters of the target page to be generated are set, the user can control the image forming device to start the copy / print operation of the original page, and convert the original page into a target all-in-one type target page through the copy / print operation. Figure 3 The "Start Copying" button 331 in the target setting interface is shown. Further, in response to the triggering operation of the "Start Copying" button 331, the image forming device may first perform a scanning operation on the original page, thereby obtaining a scanned image of the original page.

[0036] 103. Acquire each original sub-image included in the original page from the scanned image according to the original job parameters.

[0037] According to the above, the original job parameters include the scan source and the original arrangement direction of each original sub-image in the original page. After obtaining the scanned image of the original page, first, the original layout information of the original page can be determined according to the scan source, the original all-in-one type information and the original arrangement direction. Among them, the original sub-image refers to the image of the sub-page merged into the original page. The number of original sub-images in the original page is related to the original all-in-one type information of the original page. For example, assuming that the original all-in-one type information of the original page is four-in-one, then the number of original sub-images in the original page is 4. The original layout information may include position information and size information.

[0038] Specifically, the image forming device may first determine the page orientation of the scanned image according to the original image forming direction and the scanning source. In the embodiment of the present application, due to different hardware implementations, when the original page has different scanning sources, the page orientation of the scanned image obtained is different. Figure 7 As shown in the figure, when the scanning source is the platen FB, Figure 7 As shown in a, when the original imaging direction is upward, the page orientation of the scanned image is left; Figure 7 As shown in b, when the original imaging direction is downward, the page orientation of the scanned image is right; Figure 7 As shown in c, when the original imaging direction is left, the page orientation of the scanned image is upward; Figure 7 d, when the original image direction is right, the page orientation of the scanned image is downward. Figure 7 As shown in FIG. 4 , when the original image is in the upward direction, the page orientation of the scanned image is rightward; Figure 7 As shown in FIG. 5 , when the original image is in the downward direction, the page orientation of the scanned image is leftward; Figure 7 As shown in FIG. 6 , when the original image is in the left direction, the page orientation of the scanned image is upward; Figure 7As shown in h, when the imaging direction of the original is right, the page orientation of the obtained scanned image is downward. Furthermore, the image forming device can determine the original page layout information of the original page according to the page orientation of the scanned image, the original all-in-one type information of the original page, the original paper type, and the original arrangement direction. Specifically, in an embodiment of the present application, the size information of each original sub-image in the scanned image can be determined according to the original paper type and the original all-in-one type information, and then the position information of each original sub-image in the scanned image can be determined according to the page orientation of the scanned image and the original arrangement direction. The position information can be represented in the form of coordinates, for example, for any original sub-image, the coordinates of the original sub-image can be represented by the coordinates of at least two boundary points on the diagonal line of the original sub-image. For example, the upper left corner coordinates and the lower right corner coordinates.

[0039] refer to Figure 8 As shown in 8a, the original multi-in-one type of the original page is a four-in-one type, the original paper type is A4 paper type, the original arrangement direction is horizontal, and the page orientation of the scanned image is upward. According to the side length of the A4 paper type, it can be determined that when the A4 paper type is divided into 4 sub-areas, the side length of each sub-area is the size information of each original sub-image in the scanned image. It can be understood that the width of each original sub-image is The short side length of A4 paper 1 / 2 of the original sub-image. The long side length of A4 paper In the case where the coordinates of the original sub-image are represented by the coordinates of the upper left corner boundary point and the lower right corner boundary point of the original sub-image, such as Figure 8 As shown in 8a, the position of the original sub-image 1 can be represented by the coordinates of point A and point B, the position of the original sub-image 2 can be represented by the coordinates of point C and point D, the position of the original sub-image 3 can be represented by the coordinates of point E and point F, and the position of the original sub-image 4 can be represented by the coordinates of point B and point G. Then, according to the arrangement direction of each original sub-image, the position information of the original sub-images 1, 2, 3, and 4 can be determined respectively: In another example, Figure 8 As shown in FIG8b, when the arrangement direction of each original sub-image is changed to vertical, the position information of the original sub-images 1, 2, 3, and 4 will be changed to: Furthermore, the image forming device may obtain each original sub-image from the scanned image according to the original layout information of each original sub-image in the scanned image. In a specific implementation, illustratively, the image forming device may obtain the data of the original sub-image from the corresponding storage area according to the storage area of ​​each original sub-image in the scanned image.

[0040] 104. Determine target layout information of each target sub-image in the target page to be generated according to the target job parameters.

[0041] In the embodiment of the present application, when the target multi-in-one type of the target page defined by the user is other multi-in-one types that can be directly generated by the image forming device, such as two-in-one, four-in-one, eight-in-one or sixteen-in-one, the specific method for determining the target layout information of each target sub-image in the target page can refer to the aforementioned method for determining the original layout information of the original sub-image in the original page. For example, when the target multi-in-one type of the target page defined by the user is an eight-in-one type, it can be determined based on the side length of the target paper type that the target paper type is divided into eight sub-areas, and the side length of each sub-area is the size information of each target sub-image in the target page. Then, the position information of each target sub-image in the target page can be determined based on the target arrangement direction set by the user. In this way, the target layout information of each target sub-image in the target page can be obtained.

[0042] When the user-defined target page's all-in-one type is other types, such as three-in-one type, five-in-one type, etc., the specific method for determining the target layout information of each target sub-image in the target page can refer to the following description. It can be understood that the three-in-one type and the five-in-one type are only used as an example, and the following method description can also be applied to other odd-numbered all-in-one types or other even-numbered all-in-one types.

[0043] In the embodiment of the present application, according to the target all-in-one type information and the arrangement logic strategy, several candidate layout information of each target sub-image in the target page to be generated can be determined. Then, the candidate layout information that meets the preset conditions can be selected from the several candidate layout information as the target layout information.

[0044] In a possible implementation, the target layout information of each target sub-image in the target page to be generated can be determined based on the first arrangement logic. Specifically, the first arrangement logic is to arrange each target sub-image evenly along one of the edges of the target page. Specifically, based on the first arrangement logic, multiple candidate layout information of the target sub-image in the target page to be generated can be obtained first, and then, based on each candidate layout information, the area of ​​the target sub-image can be calculated respectively, and the one of the candidate layouts that makes the target sub-image area the largest is determined as the target layout information of the target sub-image.

[0045] The specific method for determining the candidate layout information of the target sub-image based on the first arrangement logic is described below.

[0046] Specifically, first, the number of target sub-images in the direction of the first target edge in the target page to be generated can be determined according to the target all-in-one type information set by the user. The first target edge can be determined according to the target arrangement direction of each target sub-image in the target page set by the user. The first target edge can be a wide edge or a long edge. When the target arrangement direction is horizontal, the first target edge can be a short edge, and when the target arrangement direction is vertical, the first target edge can be a long edge. Then, according to the number of target sub-images in the direction of the first target edge and the aspect ratio of the original sub-image, several groups of candidate sizes of each target sub-image can be determined. Furthermore, according to the number of target sub-images in the direction of the first target edge and several groups of candidate sizes of each target sub-image, several candidate layout information of each target sub-image can be determined.

[0047] The following is a method for determining several groups of candidate sizes for each target sub-image. Specifically, the first candidate side length of each target sub-image can be determined based on the side length of the first target side. The side length of the first target side can be determined based on the target paper type set by the user. Specifically, if the target all-in-one type is N-in-one, then the number of target sub-images in the direction of the first target side of the target page to be generated is determined to be N. Then, the side length of the first target side is divided into N equal parts to determine the first candidate side length of each target sub-image. Then, the second candidate side length of each target sub-image can be determined based on the first candidate side length and the aspect ratio of the original sub-image. When the first candidate side length is the width length, the second candidate side length is the height length, or when the first candidate side length is the height length, the second candidate side length is the width length.

[0048] For example, when the target arrangement direction of each target sub-image set by the user is horizontal, the target all-in-one type is three-in-one type, and the target paper size is A4 paper size, two candidate layout modes can be obtained as follows: Fig. 9 as well as Fig.10 As shown. Fig. 9Take the candidate layout mode 01 shown as an example, where the first candidate side length L1 of each target sub-image is the width length, and the second candidate side length L2 is the height length. The first candidate side length is 1 / 3 of the width length of the target paper size (A4) of L1, and the ratio of the first candidate side length L1 to the second candidate side length L2 is equal to the aspect ratio of the original sub-image. Therefore, the second candidate side length can be calculated according to the formula: Calculated, among which, is the width of the original sub-image, is the height of the original sub-image.

[0049] for Fig.10 Another candidate layout 02 is shown, Fig. 9 The candidate layout 01 shown is the opposite. The first candidate side length L1 of each target sub-image is the height, and the second candidate side length L2 is the width. The first candidate side length is 1 / 3 of the width of the target paper size (A4). The ratio of the second candidate side length L2 to the first candidate side length L1 is equal to the aspect ratio of the original sub-image. Therefore, the second candidate side length can be calculated according to the formula: Calculated. Among them, is the width of the original sub-image, is the height of the original sub-image.

[0050] Furthermore, in some implementation scenarios, the aspect ratio of the original sub-image may be inconsistent with the aspect ratio of the target paper type. In this case, when determining the candidate side lengths of each target sub-image according to the above method, one of the candidate side lengths may be greater than the side length of the target paper type. Fig.11 As shown, assuming that the target all-in-one type is three-in-one, then the first target edge ( Fig.11 The length of the target paper type (the long side of the original sub-image) is divided into three equal parts to determine the first candidate side length L1 of each target sub-image. Then, after determining the second candidate side length L2 of each target sub-image according to the aspect ratio of the original sub-image, it is found that the value of the second candidate side length L2 calculated in this way is greater than the wide side of the target paper type.

[0051] For the above-mentioned implementation scenario, in the embodiment of the present application, after determining several groups of candidate sizes of each target sub-image, it is possible to first detect whether the first candidate side length and the second candidate side length of the candidate size of each target sub-image match the side length of the target page to be generated. In the case that the first candidate side length or the second candidate side length does not match the side length of the target page to be generated, the candidate size can be corrected, and then the candidate layout information of each target sub-image can be determined according to the corrected groups of candidate sizes and the number of each target sub-image in the direction where the first target side is located. Among them, the first candidate side length or the second candidate side length does not match the side length of the target page to be generated, including that the first candidate side length is greater than the side length of the target page to be generated, or that the second candidate side length is greater than the side length of the target page to be generated. In the case that the first candidate side length and the second candidate side length match the side length of the target page to be generated, the candidate layout information of each target sub-image can be directly determined according to the candidate size and the number of each target sub-image in the direction where the first target side is located.

[0052] In another specific implementation, considering that the first candidate side length is determined based on the first target side of the target page that is bisected by the target all-in-one type, the first candidate side length will always be smaller than the side length of the target page to be generated. Therefore, it is only necessary to determine whether the second candidate side length matches the side length of the target page to be generated. Specifically, after determining the second candidate side length of the target sub-image, it is possible to determine whether the second candidate side length is greater than the length of the second target side, wherein the second target side is an edge in the target page that is perpendicular to the first target side, and the length of the second target side can be determined based on the target paper type set by the user. If the second candidate side length is greater than the length of the second target side, the candidate size of the target sub-image can be corrected so that the corrected second candidate side length is equal to the second target side length, and the corrected first candidate side length can be determined based on the corrected second candidate side length and the aspect ratio of the original sub-image. As shown in the example below: Fig.11 For example, the corrected second candidate side length Equal to the width of A4 paper, the corrected first candidate side length If the second candidate side length is not greater than the second target side length, it indicates that the target sub-image does not exceed the target page, and no processing is performed.

[0053] Through the above method, multiple candidate layout information of each target sub-image can be obtained, including size information and position information. The size information can be represented by the candidate size, and the position information can be represented by the coordinates of the target point. The target point can be, for example, a boundary point on the diagonal line of the target sub-image. Fig. 9 Taking the candidate layout mode 01 shown in the figure as an example, after the candidate side lengths of each target sub-image are determined, the position information of each target sub-image is respectively: In another possible implementation, the target layout information of each target sub-image in the target page to be generated may be determined according to the second arrangement logic. Specifically, the second arrangement logic is to arrange each target sub-image evenly in the entire target page.

[0054] Specifically, first, the method of dividing the area of ​​the target page can be determined according to the target all-in-one type information set by the user. In the case where the target all-in-one type is an N-in-one type, where N is a positive integer, if N>2 and N<=4, then it can be determined that the area of ​​the target page of the target paper type is divided into 4 parts; if N>4 and N<=8, then it can be determined that the area of ​​the target page of the target paper type is divided into 8 parts; if N=9, then it can be determined that the area of ​​the target page of the target paper type is divided into 9 parts; if N>9 and N<=16, then it can be determined that the area of ​​the target page of the target paper type is divided into 16 parts. Furthermore, the target layout information of each target sub-image in the target page to be generated can be determined according to the method of dividing the area of ​​the target page and the target arrangement direction of the target sub-image set by the user.

[0055] For ease of understanding, take the target paper type as A4, the target multi-in-one type as five-in-one type, and the target sub-image target arrangement direction as horizontal as an example. At this time, since N is 5, the area of ​​the target page can be divided into 8 equal parts to obtain 8 sub-areas. Then, according to the target arrangement direction (horizontal) set by the user, starting from the first sub-area, each target sub-image can be arranged horizontally until the 5 target sub-images are arranged. In this way, the target layout information of each target sub-image in the target page to be generated can be obtained as follows: Fig.12 The representation method of the position information and size information of each target sub-image can refer to the above description.

[0056] In another possible implementation, the two aforementioned implementations may be combined, and multiple candidate layout information of each target sub-image in the target page to be generated may be determined in accordance with the first arrangement logic and the second arrangement logic. Then, one of the multiple candidate layout information may be selected to maximize the area of ​​the target sub-image as the target layout information of each target sub-image in the target page to be generated.

[0057] Specifically, refer to Fig.13 First, according to the user Figure 3 The setting operation in the interface shown acquires the original job parameters of the original page and the target job parameters of the target page, and then, the original layout information of each original sub-image of the original page can be determined according to the original job parameters.

[0058] Then, based on the first arrangement logic, multiple candidate layout information of the target sub-image can be determined. Specifically, first, according to the target all-in-one type of the target page, the target page can be divided into equal parts according to the width (equivalent to the aforementioned first target side), and the width after the equal division is used as the width of the target sub-image (i.e., the first candidate side length), and then the height of the target sub-image (i.e., the second candidate side length) is calculated according to the aspect ratio of the original sub-image, so that the area 1 of the target sub-image can be calculated. Second, the width after the equal division can be used as the height of the target sub-image (i.e., the first candidate side length), and then the width of the target sub-image (i.e., the second candidate side length) is calculated according to the aspect ratio of the original sub-image, so that the area 2 of the target sub-image can be calculated. Third, according to the target all-in-one type of the target page, the target page can be divided into equal parts according to the height (equivalent to the aforementioned first target side), and the height after the equal division is used as the height of the target sub-image (i.e., the first candidate side length), and then the width of the target sub-image (i.e., the second candidate side length) is calculated according to the aspect ratio of the original sub-image, so that the area 3 of the target sub-image can be calculated. Fourth, the height after equal division can be used as the width of the target sub-image (i.e., the first candidate side length), and then the height of the target sub-image (i.e., the second candidate side length) can be calculated according to the aspect ratio of the original sub-image. In this way, the area 4 of the target sub-image can be calculated.

[0059] Furthermore, based on the second arrangement logic, the candidate layout information of the target sub-image can be determined. Specifically, the target page can be divided equally according to the number of target all-in-one types, and the area of ​​the target sub-image can be calculated according to the determined division method 5.

[0060] Furthermore, the target sub-images' areas 1 to 5 can be compared to determine the largest area max, and the candidate layout information when the target sub-image has the largest area can be determined as the target layout information. Then, the original image can be scaled and rotated according to the target layout information to obtain each target sub-image. Then, according to the arrangement of the target sub-images in the target page (horizontally or vertically), the coordinates of each target sub-image are determined and arranged in sequence until the arrangement is completed.

[0061] Alternatively, in another possible implementation, the image forming device may pre-store a mapping relationship table between multiple different job parameters and layout information of each sub-image in the page. Then, after obtaining the target job parameters input by the user, the mapping relationship table may be queried to directly determine the target layout information of each target sub-image corresponding to the target job parameters. With this implementation, the image forming device does not need to calculate and compare different layout methods in each implementation process, saving processing resources and improving algorithm efficiency.

[0062] 105 , pre-processing each original sub-image according to the target layout information to obtain each target sub-image.

[0063] In the embodiment of the present application, the original sub-images obtained in the original page can be scaled and rotated according to the position information and size information of each target sub-image, so as to obtain each target sub-image. The scaling process can be processed by the control module of the chip in the image forming device, for example. The chip can calculate the scaling ratio and send it to the control module for scaling. The rotation process can be processed by the image processing module of the chip in the image forming device, for example. The chip can calculate the rotation angle and send it to the image processing module for rotation.

[0064] 106. Generate a target page using each target sub-image and print it.

[0065] In the embodiment of the present application, each target sub-image obtained can be arranged on the target paper type according to the determined target layout information, so as to generate a target page and print it.

[0066] In the above technical solution, the image forming device can convert the original all-in-one type of manuscript into other all-in-one types of manuscripts by copying the original manuscript, and can support user-defined all-in-one types, thereby meeting the user's imaging needs for various all-in-one types of manuscripts. In addition, the above solution can automatically select the best typesetting solution under the currently set all-in-one type to maximize the use of paper area.
