(4) Processing Contents of Image Positioning Apparatus Next, processing contents of the image positioning apparatus of the present embodiment will be described with reference to a flowchart. FIG. 7 is a flowchart for explaining an example of the contents of the image alignment processing. First, the display content control unit 402 displays the content of the designated file on the display unit 12 (S101). As this display method, a method similar to that used in various known application software can be applied, and the contents of each page are displayed for each page.

  Next, page number display area information is acquired (S102). FIG. 8 is a diagram for explaining the page number display area. Reference numeral 451 in FIG. 8A shows an image for one page, and in the example in the figure, a page number is displayed at the lower center of the page. The page number designated as the area where the page number is displayed by dragging the mouse cursor from point a to point b, for example, using the mouse as the operation unit 311 while the page number is displayed. A display area 452 can be designated.

  The page number display area specifying unit 404 acquires the coordinates of the area specified by the mouse cursor as page number display area information, and sends it to the page number information acquiring unit 405. The page number display area can be specified using any page. In this embodiment, the specification is performed in the same manner on all pages, and the subsequent processing is performed. However, as shown in FIG. 8B, it is also possible to individually designate odd pages and even pages. This is because the display position of the page number may be different between the odd page and the even page. In this case, the specification of the page number display area 452a for odd pages is valid for pages 1, 3, 5,..., And the specification for the page number display area 452b for even pages is 2, 4, 6,. Valid on the page.

  Returning to the flowchart of FIG. 7, the page number information acquisition unit 405 obtains information about the position where the page number information is displayed for each page (hereinafter referred to as “page number display”) from the page number information display area designated by the user. (Referred to as “position information”) (S103). FIG. 9 is a diagram for explaining the contents of the page number display position information.

  The page number acquisition unit 405 extracts the page number from the page number display area by character recognition or the like, and acquires the coordinates of the position where the page number is displayed on each page as page number display position information. In the example of FIG. 9A, the coordinates of the upper left and lower right of the position where the page number “1” is displayed are acquired with reference to the position s of the upper left corner of the page. Specifically, the coordinates (xL1, yL1) of the upper left position L1 and the coordinates (xR1, yR1) of the lower right position R1 of a rectangle (indicated by a dotted line) 4531 surrounding the page number “1” are acquired. Then, it is stored in the page information storage unit 422.

  The page number acquisition unit 405 acquires page number position information for all pages. In the example of FIG. 9B, the coordinates (xL2, yL2) of the upper left position L2 and the coordinates (xR2) of the lower right position R2 of the rectangle 4532 surrounding the position where the page number “2” of the second page is displayed. , YR2) is acquired and stored in the page information storage unit 422. It is assumed that there is an image position shift between the first page and the second page, and the display positions of the page numbers “1” and “2” are also shifted. In the present embodiment, by performing image alignment using the position of the page number, it is possible to perform alignment without arranging alignment markings.

  Returning to the flowchart of FIG. 7, the reference position specifying unit 406 acquires information on an alignment reference position specified by the user via the operation unit 311 (hereinafter referred to as “reference position information”) (S104). The reference position is information that designates the position of the page number on which page the position of the image of another page is to be aligned. FIG. 10 is a diagram for explaining a reference position designation method.

  There are several methods for specifying the reference position. For example, as shown in FIG. 10A, there is a method of designating a reference position with a mouse cursor 480. In this case, for example, when the designated position uses the center position of the page number, more specifically, the page display position information according to the example of FIG. 9A, the value of (xL1 + xR1) / 2 and the mouse cursor 480 are used. The position of the image is corrected so that the x-coordinates of the designated position by match and the value of (yL1 + yR1) / 2 and the y-coordinate of the designated position by the mouse cursor 480 match. In the example of FIG. 9B, the value of (xL2 + xR2) / 2 and the x coordinate of the designated position by the mouse cursor 480 match, and the value of (yL2 + yR2) / 2 and the y coordinate of the designated position by the mouse cursor 480 are The position of the image is corrected so as to match. By performing the process of matching the display position of the page number for each page in this way, the image positioning can be performed so that the position of the image on each page matches.

Instead of using the mouse cursor 480 as described above, a window such as an example shown in FIG. 10B can be displayed on the display unit 312 and a reference position can be input using a keyboard or the like as the operation unit 311. . The alignment method is the same as described above.
Further, as shown in FIG. 10C, the reference position can be designated on the page. For example, when the first page is the reference, the center position of the page number obtained from the page number display position information of the first page, that is, the value of (xL1 + xR1) / 2 and the value of (yL1 + yR1) / 2 is used as a reference. Alignment can be performed so that the center positions of the page numbers of these pages are aligned.

  Note that the alignment process in each page after the reference position is designated is executed by the image alignment unit 407 (S105 in FIG. 7), and can be reflected in the contents of the file storage unit 421, and can also be stored in a file. The print control unit 408 can also perform print processing without reflecting the contents of the unit 421. Specifically, the image alignment unit 407 can perform image alignment by changing the margin value for each page, changing the value of each pixel constituting the image data of each page, or the like.

  Next, processing when the page number has a plurality of digits will be described. FIG. 11 is a diagram for explaining processing when the page number has a plurality of digits. In the case of a plurality of digits, as shown in FIG. 11A, the coordinates of the display position of the page number can be acquired for each number, but a plurality of alignment methods are conceivable.

  When the page number has two or more digits as shown in FIG. 11A, the center position of a rectangle enclosing all the numbers can be set as the reference position. That is, it is possible to perform alignment with other pages using the value of (xL11 + xR12) / 2 and the value of (yL11 + yR12) / 2 as a reference. The same applies to three or more digits.

  As another method, the center position of the leftmost digit or the rightmost digit can be used as a reference. In the example of FIG. 11A, when the center position of “1” that is the leftmost digit is used as a reference, the value of (xL11 + xR11) / 2 and the value of (yL11 + yR11) / 2 are used as references. Alignment with other pages can be performed. The case where “2”, which is the rightmost digit, is used as a reference can be considered in the same manner. As shown in FIG. 8B, this method is particularly effective when the page number display area is different between the odd-numbered page and the even-numbered page. Can be based on the rightmost number (and vice versa). In addition, alignment can be performed so that the display positions of the N-digit numbers are matched between pages in which the N-th digit (N is a natural number of 1 or more) is the same number.

  Further, as shown in FIG. 11B, the total number of pages (15 in the example of the figure) and the page number of the page (12 in the example of the figure) are delimiters (in the example of the figure, “/ (slash ) ”, It is possible to apply the method described above, but in addition, alignment is performed so that the position of the delimiter is almost the same on each page, Alignment with other pages can be performed based on the center position of the number indicating the total number of pages, that is, the value of (xL24 + xR25) / 2 and the value of (yL24 + yR25) / 2.

  As described above, the reference setting method for more effective alignment may differ depending on the page number display method, such as when the page number is multi-digit or includes a delimiter. It is preferable to provide a mechanism for specifying an alignment method for each file to be processed. Specifically, it is preferable to display a window for specifying the alignment method on the display unit 312 and to prompt the user to make a selection. When the page number display includes a delimiter, It is more preferable to provide a box for designating what symbol is used as a delimiter.

(Modification)
Although the embodiment of the present invention has been described above, the content of the present invention is not limited to the specific examples described in the embodiment, and for example, the following modifications may be implemented. it can.

  (1) In the above embodiment, the page number display position is acquired as a rectangular coordinate position using the result acquired by character recognition or the like. However, as one of the methods that can further improve the accuracy, A method for obtaining the font and size of numbers is conceivable. For each font and size, the accuracy of alignment can be further improved by maintaining a reference position to be aligned in each numeral.

  (2) It is not necessary to perform alignment for all pages at once, and alignment processing can be performed in several stages. For example, for pages 10 to 19, alignment is performed using the left number “1”, and for pages 20 to 29, alignment is performed using the left number “2” (the same applies to pages 30 and after). Then, for example, with pages 10 to 19 as a reference, in the next stage, alignment is performed between pages that have the same numbers on the right side (for example, for pages 22 and 32, pages 12 and Alignment is performed so that the position of “2” is substantially the same.), It is possible to realize alignment for a page with a two-digit page number. For pages with different numbers of digits, for example, as described above, the alignment of all pages can be completed by setting the center position of a rectangle enclosing all the numbers as a reference position.

  The present invention can be applied to, for example, an image alignment apparatus that performs image alignment.
