  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing a functional configuration of an image processing apparatus 10 according to the present embodiment.

  The image processing apparatus 10 is a multi-function machine having a plurality of functions such as document reading (scanning), copying (copying), printing (printing), and FAX (facsimile communication). A reading unit 11 that scans and converts it into an electrical image signal (image data), read image data (scan data) obtained by scanning a document with the reading unit 11, and a client terminal (not shown) The image processing unit 12 that performs image processing for generating print data from a print job sent from the storage unit 13, the storage unit 13 that stores various information such as scan data and operation programs, and the print data generated by the image processing unit 12 Forming unit 14 for executing an electrophotographic process based on the above and forming an image corresponding to the print data on a recording medium (recording paper), touch panel function A display / operation unit 15 comprising a large-sized bitmap display, etc., a control unit 16 for controlling the entire apparatus, such as operation control of corresponding units related to each function such as scanning, copying, printing and FAX, a client terminal (PC: personal computer) A communication interface (I / F) unit 17 that controls a communication interface when communicating with a device such as a computer via a communication network (NW).

  In the image processing apparatus 10, the reading unit 11 is a sheet feeder scanner, and is particularly configured using a DADF (Dual Automatic Document Feeder).

  In the reading unit 11 including the DADF, for example, the original set at the original setting position is conveyed from the original setting position to a predetermined reading position on the platen, and an image on one side (front surface) of the original is read and scanned. Thereafter, the document is further conveyed and reversed, and then sent back to the reading position again, whereby the other side (back side) of the document can be scanned on both sides.

  Examples of such a document to be scanned on both sides include, for example, a portrait (long portrait document) short-sided or long-sided document, a landscape (landscape document) short-sided or long-sided document on both sides. Documents (images are formed on both sides) and the like.

  Reading control such as conveyance of a document and driving of a reading sensor according to double-sided scanning of the document in the reading unit 11 is performed by a reading control unit 162 provided in the control unit 16.

  Note that in the image processing apparatus 10 according to the present embodiment, as a double-sided document to be read, for example, a binding method such as portrait short side or long side binding, landscape short side or long side binding is used. It is also possible to implement a function configuration for performing double-sided scanning using a double-page original as a two-page original.

  In this case, the reading control unit 162 opens the desired spread page of the document, sets (pushes) it on the platen, and performs the double-sided scan start operation from the display / operation unit 15. It is necessary to provide a reading control function for performing double-sided scanning of pages and storing scan data of each facing page as double-sided scan data for two pages.

  In addition to the reading control unit 162 described above, the control unit 16 of the image processing apparatus 10 includes a print control unit 161 and an image direction correction processing unit 163.

  The print control unit 161 generates print data in the image processing unit 12 based on scan data obtained by scanning the document by the reading unit 11 (or a print job received from the client terminal through the communication I / F unit 17). Then, the image forming unit 14 performs print control for forming (printing) an image based on the print data on a recording sheet and outputting it.

  The image direction correction processing unit 163 performs image editing processing such as image rotation on double-sided scan data of a document obtained by reading control of the reading control unit 162.

  In particular, according to the present embodiment, the image direction correction processing unit 163 displays a thumbnail image from the user using the UI screen (see the setting screen 50a shown in FIG. 3 and the setting screen 50b shown in FIG. 11). When a rotation instruction for a page is received, the rotation instruction is reflected not only on the page but also on a related page, and a processing function for efficiently performing image rotation correction is provided.

  The image direction correction processing function by the image direction correction processing unit 163 will be described in detail with reference to the following embodiments.

  The image processing apparatus 10 according to the first embodiment includes the functional blocks illustrated in FIG. 1 and performs a double-sided scanning process based on the flowchart illustrated in FIG.

  In the double-sided scanning process shown in FIG. 2, it is assumed that the original is double-sided scanned using DADF.

  When performing double-sided scanning of a document, a user (user) sets a document to be read at a document setting position of the DADF, and then performs a predetermined double-sided scan start instruction operation from the display / operation unit 15.

  On the other hand, the image processing apparatus 10 monitors whether a scan start operation has been performed during standby (step S101).

  Here, when a scan start operation is performed (YES in step S101), the reading control unit 162 drives each DADF of the reading unit 11 so that the front surface and the back surface sequentially pass through the reading position. (Step S102), a reading sensor (not shown) is driven to scan images on both sides of the original (step S103), and the double-sided scan data obtained by the scanning is stored in a predetermined area of the storage unit 13. Accumulate (step S104).

  When the double-sided scanning control of steps S102 to S104 is continuously performed until the double-sided scanning of the last document set is completed, the double-sided scan data of all the originals scanned on both sides are accumulated in the storage unit 13. Then, the image direction correction processing unit 163 executes a process (step S105) of correcting the image direction of each page with respect to the accumulated double-sided scan data.

  When the process proceeds to the image direction correction processing, the image direction correction processing unit 163 checks the page (image orientation is read) on the display panel of the display / operation unit 15 for reading the accumulated double-sided scan data, for example, as shown in FIG. The page designation tool 51 for designating the page to be displayed) and the page designation tool 51 for the double-sided scan data are used to read the image data of the page designated by the user and generate a thumbnail image, and the generated thumbnail The display tool 52 for displaying an image, and the rotation instruction for instructing “rotate 90 °” and “rotate 180 °” using the corresponding rotation angle instruction buttons 531 and 532 for the page on which the thumbnail image is displayed. An image direction correction setting screen (hereinafter, setting screen) 5 including a tool 53 and a “complete” button 54 for instructing completion of the image direction correction setting. 0a is displayed, and on the setting screen 50a, an instruction to rotate the image for the page on which the thumbnail image is displayed by the user using the rotation instruction tool 53 is received, and the number of the page on which the rotation instruction has been received is indicated. In accordance with the rotation angle, rotation correction processing is performed to collectively rotate and correct image data of a plurality of pages corresponding to the rotation instruction target page in the double-sided scan data at the specified angle.

  Note that the image direction correction processing in step S105 will be described in detail later with reference to FIG.

  When the image direction correction process in step S106 is completed, the control unit 16 holds the double-sided scan data in which the direction of the image of the page specified by the user is corrected as a double-sided scan result [electronic data (file)]. (Step S107).

  Thereafter, the file as the scan result is used for processing such as printing as a paper document or downloading to the user's own PC via the NW.

  FIG. 4 is a flowchart showing the detailed processing operation of the image direction correction processing in step S105 of FIG.

  In FIG. 4, the image direction correction processing unit 163 first initializes the page number of the read page received from the user and the rotation angle of the read page on the displayed setting screen 50a (see FIG. 3). S201), it is checked whether or not the editing of the document on the setting screen 50a (setting of the rotation angle of the image with respect to the page) has been completed (whether or not the “complete” button 54 has been pressed) (step S202).

  If it is determined that the document has not been edited (NO in step S202), the page number designated by the user using the page designation tool 51 [the initial value of the page number (specified by the user first). For example, “1”] is acquired (step S203), and the image data of the designated page is read out from the double-sided scan data stored in the storage unit 13 (step S204). A thumbnail image of the page is generated from the image data (step S205).

  Then, the thumbnail image is rotated according to the rotation angle being processed (step S206), and the rotated thumbnail image is displayed in the display frame of the display tool 52 on the setting screen 50a (step S207). Whether or not a user operation such as a rotation angle instruction or an editing completion instruction is performed in the state is monitored (step S208).

  Here, while the user operation is not performed (NO in step S208), the monitoring is continued. When the user operation is performed during this period (YES in step S208), the user operation (input item) is an instruction to complete editing. (Press the “Done” button 54), specify the page number (page input by the “page instruction tool” 51), select the rotation angle (“90 ° rotation instruction” button 531 or “180 ° rotation instruction” button 532) ) Is checked (step S209).

  If the user operation is a rotation angle designation (“rotation angle designation” in step S209), it is subsequently checked whether the designated angle is 90 ° or 180 ° (step S211).

  If the designated angle is 90 ° (“90 °” in step S211), the designated rotation angle is the rotation angle of the image data of all pages of the double-sided scan data stored in the storage unit 13. Add 90 ° (rotate 90 °) (step S212), and proceed to step S208.

  The image rotation operation in step S212 assumes correction of the read original in the vertical and horizontal directions.

  If the specified angle is 180 ° (“180 °” in step S211), the image data of the odd-numbered page or even-numbered page of the duplex scan data depending on whether the current page is an odd-numbered page or an even-numbered page. The designated rotation angle 180 ° is added to the rotation angle (180 ° rotation operation) (step S213), and the process proceeds to step S208.

  Note that the image rotation operation in step S213 assumes correction of the page direction of the front and back sides when a long-side-bound double-sided original is read, and the remaining angle related to a specified angle with respect to a certain page. This will also be applied to all the pages (all odd pages if the specified page is an odd page, and all even pages if the specified page is an even page). I am trying to do it.

  If the user operation accepted in step S208 is page number designation (“page number designation” in step S209), the page number being processed is updated to the value of the designated page (step S214). .

  Thereafter, the updated page number is acquired by the processing in steps S203 to S207 described above (step S203), the image data of the designated page is read out from the duplex scan data (step S204), and the read image data is read out. Then, a thumbnail image of the page is generated (step S205), the thumbnail image is rotated according to the rotation angle being processed (step S206), and the rotated thumbnail image is displayed in the display frame of the display tool 52. It is displayed (step S207).

  In this state, it is monitored whether or not a user operation such as a rotation angle instruction or an editing completion instruction has been performed (step S208). If a rotation angle is specified as the user operation ("rotation angle specification" in step S209). ) Depending on whether the specified rotation angle, the updated page number and the page is an odd page or an even page, a 90 ° rotation operation for all pages of double-sided scan data, or all even pages or all pages After performing the 180 ° rotation operation for odd-numbered pages, the process proceeds to step S108 and subsequent steps.

  As described above, while performing the process of rotating the image data of the page at the rotation angle specified by the user by confirming the direction of the thumbnail image of the page specified by the user, If an instruction to complete editing is received (“edit completed” in step S209), the process proceeds to step S202.

  When the process proceeds to step 202 and it is determined that the editing of the document is completed (YES in step S202), each page corresponding to the double-sided scan data in the storage unit 13 is determined according to the rotation angle of each page specified so far. Rotate and hold again as double-sided scan result data.

  Next, the image direction correction processing in steps S212 and S213 in FIG. 4 and the processing results will be described in more detail with specific examples.

  FIG. 5 is a conceptual diagram showing the image contents of each page of double-sided scan data according to the first specific example (see FIG. 5A) and image direction correction processing result data thereof (see FIG. 5B).

  The double-sided scan data shown in FIG. 5A is, for example, obtained when double-sided scanning is performed with two horizontally long documents set in the vertical direction (storage mode in the storage unit 13). The first and second pages correspond to the image on one side of the first document and the image on the back side, and the third and fourth pages correspond to the image on one side and the image on the back side of the second document. It corresponds.

  In the example of FIG. 5A, all the pages from the first page to the fourth page in the double-sided scan data of the original are rotated 90 degrees to the right from the upright state according to the original setting direction. Scanned in as an image [“A”, “I”, “U”, “E”].

  In the image processing apparatus 10 according to the present embodiment, when double-sided scan data as shown in FIG. 5A is obtained, the setting screen 50a (see FIG. 3) is displayed in steps S203 to S207 during the image direction correction processing shown in FIG. For example, as shown in FIG. 6A, the image “A” on the first page is displayed in the display frame of the display tool 52 in the orientation of the image before correction.

  Then, when the user selects and operates the “rotate 90 °” instruction button 531 for the image “A” on the first page in the display frame of the display tool 52 on the setting screen 50a shown in FIG. An image direction correction instruction in which 90.degree. Is designated is issued, and during the image direction correction processing shown in FIG. 4, in step S212, the image data of all pages of the double-sided scan data as shown in FIG. The operation of rotating by the designated angle (90 °) is applied, and as a result, the uncorrected double-sided scan data shown in FIG. 5A has the image orientation of each page upright after the correction. Thus, the data is corrected as double-sided scan data as shown in FIG.

  As a result, the setting screen 50a in which the thumbnail image “A” on the first page is 90 ° rightward before the correction is corrected, the thumbnail image “A” on the page is rotated and corrected in the 90 ° direction after the correction. The display contents are changed to the upright state as shown in FIG.

  When, for example, page “2” is designated by the page designation tool 51 on the display content setting screen 50a shown in FIG. 6B, double-sided scan data whose rotation is corrected by the rotation instruction for the first page [FIG. In the setting screen 50a, the thumbnail image in the display frame of the display tool 52 is switched to display contents as shown in FIG.

  Thereby, the user can confirm that the rotation correction for the first page is also applied to the second page, and can confirm the other pages in the same manner.

  FIG. 8 is a conceptual diagram showing the image contents of each page of double-sided scan data (see FIG. 8 (a)) and image data (see FIG. 8 (b)) as a result of the image direction correction processing according to specific example 2. is there.

  The double-sided scan data shown in FIG. 8A is, for example, obtained when double-sided scanning is performed on two originals with long side binding (a storage mode in the storage unit 13). The first and second pages correspond to the image on one side of the first document and the image on the back side, and the third and fourth pages correspond to the image on one side and the image on the back side of the second document. Yes.

  In the example of FIG. 8A, the second page and the fourth page are the images in which the first page and the third page are established in the double-sided scan data of the original depending on the setting direction of the long side bound original. Is scanned in as an image in an inverted state (a state rotated 180 degrees from an upright state).

  When double-sided scan data as shown in FIG. 8A is obtained by the image processing apparatus 10 of the present embodiment, during the image direction correction processing shown in FIG. 4, in steps S203 to S207, the setting screen 50a includes, for example, As shown in FIG. 9A, the image “A” of the first page is displayed in an upright state in the display frame of the display tool 52. From this state, the page designation tool 51 reads “2” as the read target page. When the page is designated, the setting screen 50a is switched to the display content in which the image “B” on the second page is displayed in the orientation before the correction in the display frame of the display tool 52, as shown in FIG. 9B.

  Then, the user sets “180 °” to the image “B” on the second page displayed in an inverted state in the display frame of the display tool 52 on the display content setting screen 50a shown in FIG. When the “rotate” instruction button 532 is selected and operated, an image direction correction instruction in which the rotation angle is designated as 180 ° is issued. During the image direction correction process shown in FIG. 4, in step S213, both sides as shown in FIG. An operation for rotating the image data of even-numbered pages (second and fourth pages) of the scan data by the designated angle (180 °) is performed, and as a result, both sides before correction shown in FIG. The scan data is corrected as double-sided scan data as shown in FIG. 8B in which the orientation of the image on each page is all upright after correction.

  As a result, before the correction, the setting screen 50a (see FIG. 9B) in which the thumbnail image “B” on the second page is overturned is displayed as shown in FIG. The display content as shown in FIG. 9B, in which the image “B” is rotationally corrected to the upright state to be in the upright state, is switched.

  Thus, the user can confirm that the 180-degree rotation correction for the second page has been correctly performed. Similarly, when the fourth page is read and designated, the image “D” on the fourth page is designated. It can be confirmed that is correctly corrected to the upright state.

  As described above, in this embodiment, the orientation of the image of each page of the double-sided scan data is confirmed one page at a time, and for example, by instructing the rotation by 90 °, the images of all pages in the double-sided scan data are displayed. 90 ° rotation correction can be performed at once.

  Further, for example, by instructing the page whose image orientation is confirmed to be rotated by 180 °, if the page is an odd page, all odd pages are corrected to an image rotated by 180 °. If the page is an even page, it is possible to obtain double-sided scan data corrected to an image in which all even pages are rotated by 180 °.

  The image processing apparatus according to the second embodiment (referred to as 10B for convenience) includes the functional blocks illustrated in FIG. 1, but the image direction correction processing unit 163 includes the image processing apparatus 10 according to the first embodiment ( An image direction correction processing unit (referred to as 163b for convenience) having a processing function different from that of FIG.

  In other words, in the image processing apparatus 10B according to the present embodiment, the image direction correction processing unit 163b uses a setting screen 50b as shown in FIG. 11, for example, which is different from the first embodiment, as the UI for image direction correction setting. .

  As shown in FIG. 11, the setting screen 50b displays, for example, thumbnail images of two preset pages (in this example, the first page (even page) and the second page (even page)) (see FIG. 11). The two-page image may be configured to be scrollable backward and forward in units of two pages by the page designation tool 51b, and the first and second pages without the page designation tool 51b. The display tools 52a and 52b are provided, and rotation angle instruction tools 53a and 53b are provided corresponding to the display tools 52a and 52b, respectively.

  The rotation angle instruction tools 53a and 53b are respectively provided with rotation angle instruction tools 531a and 531b for instructing to rotate the image of the page displayed on the corresponding display tools 52a and 52b. Rotation angle instruction tools 532a and 532b for instructing rotation to “rotate 180 °”.

  Similar to the image processing apparatus 10 according to the first embodiment, the image processing apparatus 10B according to the present embodiment executes the double-sided scanning process as illustrated in FIG. 2, and during the double-sided scanning process, in the step S105, the setting screen 50b described above. (See FIG. 11), the image direction correction processing according to the flowchart shown in FIG. 12 is executed.

  In FIG. 12, processing steps similar to the processing steps of the image direction correction processing (see FIG. 4) in the image processing apparatus 10 of Embodiment 1 are denoted by the same reference numerals.

  In the image direction correction processing shown in FIG. 12, the image direction correction processing unit 163b first initializes the page number and the rotation angle of each page (step S201), and then completes the document editing, as in the first embodiment. Is checked (whether or not the “complete” button 54 has been pressed) (step S202).

  If it is determined that the editing of the document has not been completed (NO in step S202), the image direction correction processing unit 163b corresponds to two pages set in advance in the double-sided scan data stored in the storage unit 13. [For example, the first page and the second page (one page each for even pages and one odd page)] are read (step S204b), and thumbnail images of the respective pages are generated from the read image data of each page. (Step S205b).

  Next, the generated thumbnail image of each page is rotated according to the rotation angle being processed (step S206b), and the thumbnail image of the first page after the rotation is displayed as a display frame (Page1 display frame) of the display tool 52a. The thumbnail image of the second page is respectively displayed in the display frame (Page 2 display frame) of the display tool 52b (step S207b), and in this state, a user operation such as a rotation angle instruction or an editing completion instruction has been performed. Whether or not is monitored (step S208b).

  Here, while the user operation is not performed (NO in step S208b), the monitoring is continued. When the user operation is performed during this period (step S208b YES), the user operation (input item) is an instruction to complete editing.
