Description

  The present invention relates to an information processing apparatus, method, and program for efficiently displaying an image read by an image reading apparatus such as a scanner.

  In recent printed matter, many Nin1 printing and saddle stitch binding printing have been performed. Nin1 printing is imposition printing in which N pages of logical pages are arranged so as not to overlap on one printing surface, and 2in1 and 4 logical pages are arranged on one printing surface. 4-in-1 printing is often used. Here, the logical page is a page in the structure of document data. Saddle-stitched bookbinding is a booklet-like printed material by stacking a plurality of papers with two logical pages on one printing surface, folding them into two, and performing staples along these folds. This is a printing method to be generated. These printing methods are printing methods in which a plurality of logical pages are arranged on one printing surface, and have an advantage of efficiently placing printing information on a limited printing surface.

  On the other hand, a scanned image of a document printed by Nin1 printing or saddle stitch binding has a plurality of logical pages on one printing surface. Therefore, if these scanned images are displayed as they are with an image display software or the like, the viewability is improved. There is a problem that is not good. In the case of Nin1 printing, the logical pages are not always aligned in a straight line, such as from left to right or from top to bottom, so the user needs to read the scanned image in consideration of the logical page arrangement order. is there. In particular, in the case of saddle stitch bookbinding, in order to efficiently scan using an ADF (Automatic Document Feeder), if the original is scanned with the staples removed, the arrangement order of the logical pages is complicated. Scan image. Therefore, in order to read a scanned image in the scanned state according to the order of logical pages, frequent movement of the display area of the page across physical pages (corresponding to one side of the printed matter) is performed. Accompany. For this reason, there is a problem that the user operation related to browsing becomes complicated and it is difficult to follow the order of pages.

  Conventionally, various methods have been used to cope with this problem. For example, in Patent Document 1, when a document including a plurality of logical pages on one surface such as Nin1 or saddle stitch bookbinding is scanned by a scanner, each logical page of the scanned image is recognized and the logical page images are rearranged. To create a document file.

JP 2007-13799 A

  In the conventional solution shown in Patent Document 1, the scan image is decomposed into logical pages, the images of the decomposed logical pages are rearranged, and a function for creating a new document file is provided on the scanner side or other information. Software that edits scanned images on the device is required. These functions are often not implemented in an inexpensive scanner device because of manufacturing / development costs, and thus are not always available. On the other hand, when editing scanned images with software on information devices, page splitting, rearrangement, and creation of new image files are relatively heavy processes, so they are cheap and easy to use on mobile terminals, etc. When these processes are performed with a low device, there is a concern that the process takes time. Furthermore, since a new image file is also generated, there is a problem that the consumption of the storage area increases and the data managed by the user increases. Note that when logical page division, rearrangement, and new document file generation processing are performed on the scanner side, the image data received on the information device side is processed image data that has already been edited. For this reason, for example, when it is desired to create a copy of the original scan data, some processing or setting may be required.

  The present invention has been made in view of the above-described conventional example, and an object thereof is to provide an information processing apparatus, method, and program that reduce processing load, suppress required storage capacity, and improve operability. And

  In order to achieve the above object, the present invention has the following configuration.

An information processing apparatus capable of displaying, for each page, one or more sheet images in which one or more page images are arranged on one surface,
Setting means for determining imposition of a page based on the position and range of a blank area included in the image of the one or more sheets, and storing the determined imposition as imposition information ;
When displaying a designated page, based on the imposition information, out of the image of the one or more sheets, a determination unit that determines a sheet corresponding to the designated page and a position and a range in the sheet;
Display control means for displaying the image of the determined page on the display unit as the image of the designated page .

  According to the present invention, it is possible to realize display in units of pages of a scanned image to which a special layout such as Nin1 printing or saddle stitch binding printing is applied with a light processing load, a suppressed storage capacity, and good operability. For example, it is expected that user operability related to browsing of scanned images of Nin1 printing or saddle stitch binding printing will be improved. In addition, since the method of the present invention is compatible with the display method, the processing is light, and an effect that can be easily realized even with a device having a relatively low processing capability such as a mobile device is exhibited. Further, since the original scanned image is used as it is and a new image data file is not generated, there is an advantage that the load on the user associated with document management can be reduced.

  In the method of the present invention, the original scan image is held as it is. For this reason, there is also a merit that the degree of freedom in reusing the original scan image is high. For example, an original scanned image of saddle stitching can be printed as it is, folded in half at the center, and saddle stitched along the crease, so that a copy of the original printed material can be easily created.

[Screen Description]
FIG. 6 is a flowchart showing the operation of the software 220 of the present invention. Hereinafter, the description of the present invention will be continued along the processing flow shown in FIG. FIG. 6 is executed by the CPU 12. However, each step belongs to a different software module. In the following description, it is assumed that the software module to which each process belongs is the execution subject. When the user activates the application 220 of the present invention, the application 220 executes various initialization processes (S301), and displays a screen as shown in FIG. 7 on the display 10 of the information terminal 100.

  FIG. 7 is an example of a display screen of the application 220 when the information terminal 100 is assumed to be implemented on a mobile information device 400 such as a smartphone. The mobile information device 400 includes a touch panel display 410. The user touches an area in the display 410 to give various operation instructions to the application 220. That is, the display screen of FIG. 7 constitutes a user interface. The application 220 includes an image display area 420 for displaying the read image, and buttons 421 to 425 for receiving various requests from the user. The “Open” button 421 is used to specify an image data file to be loaded into the application 220, and the “Setting” button 422 changes the imposition layout for displaying the image data already displayed in the image display area 420. Use for. Further, the page move buttons 423 and 424 are used to advance the page of the image data displayed in the image display area 420 to the page immediately after the currently displayed page, or to return to the page immediately before that, An “end” button 425 is used to end the application 220. That is, the page movement button is a button for designating a display target page (designated page).

  When the user touches the “end” button 425, the input unit 221 determines this (S310), and the application 220 performs a termination process (S311) and terminates itself.

[Explanation when opening a file]
Returning to FIG. 6, the processing of this embodiment will be described while following the processing flow when the file is opened. When the user touches the “open” button 421, the input unit 221 determines this (S320), and the image data reading unit 222 performs image data reading processing. The image data reading unit 222 displays in the image display area 420 an “open file” dialog (generally not shown) for designating an image data file to be opened by the user. The image data reading unit 222 reads the image data file designated in the “open file” dialog into a memory such as the RAM 3 (S321).

  Thereafter, the imposition information setting unit 223 displays a dialog for setting the imposition of the read image data in the image display area 420 so that the user can set the imposition of the read image data file (S322). . When the layout setting process (S322) is completed, the imposition information setting unit 223 internally initializes the logical page counter to 1. By performing this initialization, the first logical page displayed after the layout setting process (S322) becomes the first logical page. For this reason, when the user performs a layout different from the layout of the read image data file, the user can easily notice a mistake.

(Example of layout setting screen and imposition information)
FIG. 8 is a screen showing an example of a layout setting dialog 500 displayed on the image display area 420 by the imposition information setting unit 223 in the process of S322. On this screen, the user can enter “layout” (layout setting 510) indicating the layout of Nin1 or saddle stitch binding, “printing direction” (printing direction or direction setting 520) indicating the orientation of each logical page, and each layout. The “arrangement order” (arrangement order setting 530) indicating the corresponding logical page arrangement order can be set. These three pieces of information are hereinafter referred to as “imposition information”.

  FIG. 9 is a diagram showing a list of setting items and setting combinations of layout settings 510, print orientation settings 520, and arrangement order settings 530 that can be set in the layout setting dialog 500. The imposition information setting unit 223 according to the present embodiment sets any one of four ranges of “1 in 1 (standard)”, “2 in 1”, “4 in 1”, and “bookbinding” as a layout setting 510 in a normally used range. Is possible. In the print orientation setting 520, “vertical” and “horizontal” can be selected without limitation. In addition, when the layout setting is “1 in 1 (standard)”, the imposition information setting unit 223 controls the arrangement order setting 530 so that it cannot be selected because it is not necessary. When the layout setting 510 is “2 in 1”, the options of the arrangement order setting 530 are changed according to the setting value of the print orientation setting 520. For example, when the direction setting 520 is “vertical”, the arrangement order is “left to right” or “right to left”, and when the direction setting 520 is “horizontal”, “top to bottom” or “bottom to top” "Is controlled to be selectable. On the other hand, when the layout setting 510 is “4 in 1”, the arrangement order setting 530 can be selected from four from “upper left to right”, “upper left to down”, “upper right to left”, and “upper right to lower” To control. Even when the layout setting 510 is “bookbinding”, the options of the arrangement order setting 530 are changed according to the setting value of the print orientation setting 520. For example, when the print orientation setting 520 is “vertical”, “left open” or “right open” is set as the arrangement order setting 530, and when the print orientation setting 520 is “horizontal”, the arrangement order setting 530 is “ Control is performed so that “upper opening” or “lower opening” can be selected.

  FIG. 10 is a diagram showing all combinations of imposition information that can be set in the present embodiment. In FIG. 10, the number in the rectangle indicates the logical page number, and the number at the bottom of the rectangle indicates the physical page number. When the layout setting 510 is “1 in 1 (standard)”, regardless of whether the print orientation setting 520 is “vertical” or “horizontal”, one logical page is arranged on one physical page surface. When the layout setting 510 is “2 in 1”, two logical pages are arranged on one physical page surface, and when the print orientation setting 520 is “vertical”, the arrangement of the logical pages is divided into left and right. "Is divided vertically. The arrangement order setting 530 indicates the arrangement order of logical pages on one physical page plane (the page advance direction). In the case of “2 in 1”, the printing direction of the physical page is always different from the printing direction of each logical page.

  When the layout setting 510 is “4 in 1”, four logical pages are arranged on one physical page surface, and one logical page is an area obtained by dividing the physical page surface into four regardless of the setting of the print orientation setting 520. Will enter. If the arrangement order setting 530 is “upper left to right”, the logical page is arranged from the upper left to the right, moved to the lower left and then moved to the right, and if “upper left to lower”, the upper left to the lower Go to, move to the upper right, then go down. Similarly, if the arrangement order (530) is “from the upper right to the left”, the process proceeds from the upper right to the left, moves to the lower right, and then proceeds to the left. If it is “downward from the upper right”, it proceeds from the upper right to the lower, moves to the upper left, and then proceeds downward.

  When the layout setting 510 is “bookbinding”, it is assumed that the printed material is bound and printed at the center line of the printed sheets and folded in two along the binding line. The scanning is premised on that the sheets, which have been bound in the reverse order of the bookbinding, are carried out in the order of front and back from the innermost sheet to the back in the bound state. In the “bookbinding” setting, as in “2 in 1”, two logical pages are arranged on one physical page surface. When the print orientation setting 520 is “vertical”, the layout of logical pages is divided into left and right, and when it is “horizontal”, it is divided into upper and lower. When the layout setting is “bookbinding”, the arrangement order of the logical pages becomes complicated. Therefore, in this embodiment, the setting item name of the arrangement order setting 530 is not a name that directly indicates the arrangement order of the logical pages, but is a binding. In order to advance the page in the state where it is being specified, it will be specified in the opening direction. When the print orientation setting 520 is “vertical” and the arrangement order setting 530 is “left open”, the first logical page is arranged on the right side of the first physical plane, and the second logical page is arranged on the back side thereof. . When the print orientation setting 520 is “horizontal” and the arrangement order setting 530 is “upward open”, the first logical page is arranged below the first physical surface, and the second logical page is arranged on the back surface thereof. The When the print orientation setting 520 is “vertical” and the arrangement order setting 530 is “right open”, the first logical page is arranged on the left side of the first physical plane, and the second logical page is arranged on the back side thereof. . When the print orientation setting 520 is “horizontal” and the arrangement order setting 530 is “open downward”, the first logical page is arranged above the first physical surface, and the second logical page is arranged on the back surface thereof. . In FIG. 10, four sheets are bound, but the present invention is not limited to this. Therefore, when the layout setting is “bookbinding”, the number of sheets to be bound may be set.

  Although FIG. 10 is shown for convenience of explanation, imposition information such as layout setting, print orientation setting, and arrangement order setting, and a specified logical page number (counter) are used as input parameters, and the corresponding logic is shown. By realizing FIG. 10 as a table that defines the number of the physical page including the page and the range of the designated logical page occupied in the physical page, the physical page ( That is, it is possible to specify a logical page included in an image data file corresponding to the physical page and display it. This table is referred to as an imposition-page correspondence table. That is, referring to FIG. 10 is synonymous with searching the imposition-page correspondence table. Of course, the imposition-page correspondence table is an example for associating the logical page with the image data file, and the association between the logical page and the image data file is not limited to the table.

(Display area setting process)
Returning to the description of the processing flow in FIG. After setting the imposition information in the layout setting process (S322), the display area setting unit 224 performs the display area setting process (S323). The display area setting unit 224 refers to the imposition information set in the layout setting process (S322), and the position of the logical page indicated by the current logical page counter is the number of pages (that is, the number of sheets) of the currently read image data file. ) To determine which position and range of (). This indexing is performed with reference to the imposition-page correspondence table shown in FIG.

  Referring to FIG. 10 again, the logical page position indexing process will be described by way of example. For example, if the layout setting 510 is “4 in 1”, the print orientation setting 520 is “vertical”, the arrangement order setting 530 is “upward from left to right”, and the current logical page counter is 9, this corresponds to FIG. The position of the logical page is the upper left of the third page. Accordingly, the display area setting unit 224 sets the upper left area of the third page as the display area. Similarly, if the layout setting 510 is “bookbinding”, the print orientation setting 520 is “vertical”, the arrangement order setting 530 is “left open”, and the logical page counter is 3, the display area setting unit 224 displays the third page. The left half area is set as the display area. The initial value of the logical page counter is set to 1.

(Logical page display processing)
Returning to FIG. 6, after the display area setting unit 224 sets the display area in the display area setting process (S 323), the image data display unit 225 creates an image corresponding to the display area of the image data file, and the image display area 420. Process to be displayed.

  Thus, the process at the time of opening the file is completed, and the application 220 waits for a command input from the user. In FIG. 11, the position of the display area for the image data file in the above two examples is indicated by a rectangular area surrounded by a broken line, and a logical page image corresponding to the image display area 420 is displayed. An example is shown.

[Description of other commands]
The application 220 according to the present embodiment performs control so that only the “open” button 421 and the “end” button 425 in FIG. 7 can be operated when the file is not opened. Therefore, the application 220 checks whether or not the file is open (S330 in FIG. 6). If the file is not open, the “set” button 422 and the “page move” buttons 423 and 424 do not function. Control.

  Returning to FIG. 6, when the user touches the “set” button 421, the input unit 221 determines this (S 340), performs the layout setting process (S 322) described above, and then performs the display area setting process (S 323). Then, a logical page display process (S324) is performed. By performing processing in this way, the user can always set imposition information again when the image data file is opened, and can confirm the display of the logical page by the newly set imposition. Become. Since the display process itself is performed via the operating system, S324 can also be referred to as a display control process. In S323, “setting” is referred to as processing for determining the position and range of the logical page.

  When the user touches the “page move” buttons 423 and 424, the input unit 221 determines this (S350), and performs the current logical page counter update process (S351). The application 220 increments or decrements the current logical page counter in response to a command for advancing or returning a logical page. Thereafter, the display area setting process (S323) and the logical page display process (S324) described above are performed. In this way, the user can continue to read the page without being aware that the image data file currently being viewed is a document that has been bound in Nin1 or saddle stitching, thereby improving readability. Contribute to. FIGS. 11A and 11B are examples described above, and are diagrams showing how the display area in the image data file changes when the page is advanced or returned by the direction of the arrow. It is.

[Imposition information automatic judgment processing]
As described above, in the present embodiment, in the layout setting process (S322) of FIG. 6, the user sets the imposition information of the image data file, sets the display area according to the set imposition information, The logical page portion is displayed. Therefore, in order to perform correct display, the imposition information set in the layout setting process (S322) needs to be set correctly. However, the user of the application 220 is not necessarily looking at the original document, and it is sufficiently assumed that imposition information setting in the layout setting process (S322) is difficult. In particular, in the case of an image printed by saddle stitching, it is considered difficult to determine imposition information only by looking at the printed surfaces of several scanned images. Based on the above, a process for determining (or estimating) imposition of an image data file that is currently opened using the imposition information determination unit 226 for the purpose of assisting the user in setting operation on the layout setting screen 500 Do further. The imposition information setting unit 223 assists the user in setting the imposition information by displaying the imposition information determined to be most likely in the imposition determination process as the initial display value of the layout setting screen 500. .

  The determination by the imposition information determination unit 226 is performed by determining what imposition has been performed by looking at the position and shape of an area where drawing is not performed, which occurs due to imposition. However, this determination method may not be correctly determined depending on the combination of the number of logical pages, layout settings, and arrangement order. As described above, when a plurality of imposition information items are listed as candidates, the most general imposition information among them is displayed on the layout setting screen 500.

  The automatic imposition determination function by the imposition information determination unit 226 operates when the layout setting process (S322) is called from the “open” command 421, and does not function when called from the “setting” command 422. To control. That is, the imposition determination process by the imposition information determination unit 226 is applied only when the layout setting process (S322) is first performed on the open image data file. For this reason, when some imposition information is set, the setting value is the imposition information already set when the layout setting screen 500 is opened.

  The automatic imposition determination process by the imposition information determination unit 226 will be described with reference to the flowchart in FIG. 12 and the table in FIG. FIG. 12 is a flowchart showing processing until the layout setting screen 500 is opened in the layout setting processing in step S322. First, in the automatic imposition determination process by the imposition information determination unit 226, it is determined whether the layout setting process (S322) is called from the “open” command 421 or the “setting” command 422. (S610). If it is not called from the “Open” command, the layout setting screen 500 is opened with the currently set value as a normal process (S620).

  First, the table of FIG. 13 will be described. This table determines the imposition image based on the shape and position of the undrawn area (blank area) of the first page and last page in the image data file, and the physical page print orientation. It shows the possibility of data. Further, when there is a possibility of a plurality of impositions, possible impositions that are most likely to be used among the plurality of impositions are described as “layout to be adopted”. In FIG. 13, the orientation of the physical page and the range of the blank area are shown in the figure. However, in the procedure of FIG. For example, the direction of the physical page can be realized by determining by the aspect ratio of the image or by determining by character recognition. Further, the range of the blank area can be determined by determining whether or not it is blank for each area obtained by dividing the physical page into a tabular shape, and combining the results. If the image data file is obtained by scanning a document, noise due to dust or toner scattering may be included in the blank area. Therefore, noise removal processing may be performed prior to determination of the blank area range. This processing may be performed by an image reading apparatus or an information terminal.

  For example, if the paper orientation of a physical page is vertical and the right half of the last page is a blank area, the layout setting 510 is “4 in 1”, the print orientation setting 520 is “vertical”, and the arrangement order setting 530 is “ It is shown that it can be determined that it is “downward from the upper left”. It should be noted here that the orientation of printing shown in FIG. 10 and the like is the direction of logical pages, whereas the object of determination in the procedure of FIG. 12 is the orientation of paper, that is, the image data is vertically long. (Longitudinal direction) or landscape (horizontal direction). Furthermore, for example, if the paper orientation is horizontal and the right half of the last page is a blank area, there is a possibility of “2 in 1” “vertical” “left to right” or “4 in 1” “horizontal” “down from upper right”. Show. In this case, since the former is more frequently used imposition, the former is shown as “layout to be adopted” of this pattern. Since there is no blank area on the page where the last drawing exists, the layout setting 510 is set to “1 in 1 (standard)”, and the print orientation setting 520 is set to “vertical” according to the orientation of the physical page. "Also" or "Landscape".

  The description returns to the processing of S610 in FIG. If it is a call from the “Open” command, the imposition information determination unit 226 searches for a blank area for the first physical page (S630), and whether or not the searched blank area pattern exists in the table of FIG. Is confirmed (S640). If the searched blank area is in the table of FIG. 13, the imposition corresponding to this is set in the layout setting screen 500 (S650). Note that the imposition is determined by the blank area state of the first page when the layout is bookbinding.

  If the pattern of the blank area of the first page searched in the determination of S640 is not in the table of FIG. 13, the imposition information determination unit 226 investigates the pattern of the blank area of the last physical page. If all the last physical pages examined are blank areas (Yes in S670), the previous physical page is set as the last physical page (S680), and the blank area is searched again. In other words, the back side of double-sided printing tends to be blank because of imposition, and the pattern of the blank area is examined with the last drawn page as the last physical page. When the detected blank area pattern is in the table of FIG. 13 (Yes in S690), the imposition information determination unit 226 sets the imposition described as the “adopted layout” of the corresponding pattern in FIG. The screen 500 is set (S650). Even if there is no blank area in the last physical page, the imposition information determination unit 226 follows the table in FIG. 13, the layout setting 510 is “1 in 1 (standard)”, and the print orientation setting 520 is the physical page orientation. “Vertical” or “Horizontal” is set in the layout setting screen (500).

  Even when there is no corresponding pattern (Yes in S690), the imposition information determination unit (226) sets the layout (510) to “1 in 1 (standard)” and the print direction (520) is directed to the physical page. "Vertical" or "Horizontal" is set in the layout setting screen (500).

  The imposition information determined as described above is stored in the information terminal as the initial value or candidate value of the imposition information specified for the image data to be displayed and presented to the user. The user can correct the initial value if it is incorrect.

  With the above procedure, the information terminal can display the image data obtained by scanning the document for each logical page included in the image data in the order of pages by a simple operation. Further, since the image data is not processed at this time, the processing load is light and a large number of storage areas are not required in addition to the storage area required for the image data itself. Furthermore, since the imposition information necessary for specifying the arrangement of the logical pages included in the image data can also be specified from the target image data, the burden on the user can be further reduced.

[Other Examples]
In the above-described embodiment, the scan image is received from the image forming apparatus. However, if the information terminal includes a camera, an image acquired by photographing a document such as a book with the camera is used. The present invention can also be implemented in place of the scanned image of the embodiment. However, in this case, since the image is not data described in PDL but an image object itself, processing for dividing one image data into pages and extracting a page image according to a designated layout is performed. Done. In this case, the captured image is included in the scanned image referred to in the above embodiment.

  The present invention can also be realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, or the like) of the system or apparatus reads the program. It is a process to be executed.
