  Note that the mobile phone 10 and the first access point 62 are configured to perform wireless communication (using radio waves) conforming to a wireless LAN infrastructure mode (a mode in which a plurality of wireless LAN terminal devices perform data communication via an access point). Data communication) 211 can be performed. That is, when the mobile phone 10 accesses the first access point 62 and can perform the wireless communication 211 conforming to the infrastructure mode of the wireless LAN, the mobile phone 10 can perform data communication with the MFP 51 via the first access point 62. Is possible. An example of the wireless LAN system is a communication system defined by the IEEE 802.11a / b / g / n standard, for example.

  The configuration of the mobile phone 10 will be described. As shown in FIG. 1, a mobile phone 10 includes a CPU (Central Processing Unit) 11, a storage unit 12, a wireless transmission / reception unit 15, a wireless antenna unit 16, a button input unit 17, a panel 18, a mobile phone transmission / reception unit 22, and a mobile phone. An antenna unit 23 and an inclination sensor (also called a gyroscope) 29 are mainly provided. In addition, a speaker 3 and a microphone 4 are provided to perform a call and voice input.

  The CPU 11 executes processing according to the program 21 in the storage unit 12. Hereinafter, the CPU 11 that executes a program such as the viewer application 21a or the operating system 21e may be simply described by a program name. For example, the description “the viewer application 21 a is” may mean “the CPU 11 that executes the viewer application 21 a”. The storage unit 12 is configured by combining a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, an HDD (Hard Disk), a buffer included in the CPU 11, and the like. The wireless transmission / reception unit 15 performs wireless communication 211 conforming to the infrastructure mode of the wireless LAN via the wireless antenna unit 16. In addition, the mobile phone transmission / reception unit 22 performs wireless communication 210 based on the mobile phone communication method with the base station 61 via the mobile phone antenna unit 23. And the digital signal which comprises various data is transmitted / received by the wireless transmission / reception part 15, the mobile telephone transmission / reception part 22, etc. FIG.

  The storage unit 12 stores a program 21. The program 21 includes a viewer application 21a, a scan application 21b, and an operating system 21e. The viewer application 21a is an application for causing the CPU 11 to execute processing for causing the panel 18 to display an image represented by image data stored in the image file storage area 12b. The scan application 21b is an application for causing the CPU 11 to execute a process for generating an image file (scan process) in the MFP 51 and a process for receiving the image file generated by the MFP 51 from the MFP 51.

  The operating system 21e is a program that provides basic functions that are commonly used by the viewer application 21a and the scan application 21b. The operating system 21e includes a program for causing the mobile phone transmission / reception unit 22 to execute communication, a program for causing the wireless transmission / reception unit 15 to execute wireless communication 211, and the like. The operating system 21e is also a program that provides an API (Application Programming Interface) for each program to acquire information calculated by the tilt sensor 29 or the like, or for each program to instruct various hardware.

  The storage unit 12 includes a set value storage area 12a and an image file storage area 12b. The setting value storage area 12a stores a file type flag, a selected image page number, display settings, and the like, which will be described later. The file type flag is information representing the file type of a display target image file (display target image file). An example of the file type is a book file. A book file is a file in which a plurality of images represented by a plurality of image data included in an image file are in a relationship (spreading relationship) in which left and right pages are provided for every two consecutive images. As the selected image page number, which page number image is selected as the “selected image G1” to be displayed from among a plurality of images represented by each of a plurality of image data included in the image file. Is a page number indicating.

  The display setting is a setting related to a mode of displaying an image on the panel 18. The display settings include “one-screen display mode”, “right-bound spread mode”, “left-bound spread mode”, and the like. The “single screen display mode” is a mode in which only one image is displayed on the panel 18. The “right binding spread mode” is a mode in which the page numbers of images advance from right to left when two images are displayed on the left and right pages. That is, the page number of the right image is a smaller number than the page number of the left image. The “right binding spread mode” is mainly used when displaying an image including vertically written text. The “left-binding spread mode” is a mode in which the page numbers of images advance from left to right when two images are displayed on the left and right pages. In other words, the page number of the left image is a smaller number than the page number of the right image. The “left binding spread mode” is mainly used when displaying an image including a horizontally written sentence.

  The image file storage area 12b is an area for storing a plurality of image files. One image file includes a plurality of image data. Each of the plurality of image data displays a different image. A plurality of images represented by a plurality of image data are assigned a page order which is a consecutive number. In this specification, “an image represented by image data included in an image file” may be described as “an image included in an image file”.

  An example of an image file is a file obtained by scanning one book. In this case, an image obtained by scanning each page of the book corresponds to a plurality of images included in the image file. In addition, the page order of the plurality of images included in the image file is an order corresponding to the page order of the book.

  The plurality of images included in the image file may be portrait images. The portrait image faces the display surface of the panel 18 when the panel 18 having a rectangular area is placed so that the short side extends in the horizontal direction and the long side extends in the vertical direction (so-called vertical placement). This is an image in a direction in which the user can correctly view the display content of the display image. A concept corresponding to a portrait image is a landscape image. The landscape image is a user who faces the display surface of the panel 18 when the panel 18 having a rectangular area is placed so that the long side extends in the horizontal direction and the short side extends in the vertical direction (so-called horizontal placement). Is an image in a direction in which the display content of the display image can be correctly viewed.

  The button input unit 17 receives an operation by the user of the mobile phone 10. The button input unit 17 is configured integrally with the panel 18 as a touch panel. The panel 18 displays various function information of the mobile phone 10. The display surface of the panel 18 has a rectangular shape having a short side and a long side. The tilt sensor 29 is a sensor that measures the tilt angle at which the mobile phone 10 is tilted with respect to the horizontal plane by detecting the angular velocity.

  The mobile phone 10 is a model for both vertical and horizontal. The vertical / horizontal model is a model that allows the user to operate the mobile phone 10 correctly regardless of whether the panel 18 is oriented vertically or horizontally. The vertical direction of the panel 18 is a direction in which the short side of the panel 18 having a rectangular shape extends in the horizontal direction and the long side extends in the vertical direction. The horizontal direction of the panel 18 is a direction in which the long side of the panel 18 having a rectangular shape extends in the horizontal direction and the short side extends in the vertical direction.

<Operation of mobile phone>
The operation of the mobile phone 10 according to the first embodiment will be described with reference to FIGS.

<Operation of scan application>
Processing for acquiring and storing an image file using the scan application 21b will be described with reference to FIG. When receiving an input of a user operation for starting the scan application 21b via the button input unit 17, the CPU 11 starts the scan application 21b. Then, the flow of FIG. 5 is started.

  In step S <b> 446, the CPU 11 determines whether an instruction to execute scan processing in the MFP 51 is input. If no command is input (S446: NO), the process returns to S446, and if input (S446: YES), the process proceeds to S448. In step S <b> 448, the CPU 11 transmits a command for executing the scanning process to the MFP 51 via the wireless communication 211. In response to receiving the command, the MFP 51 scans a document set on a document table (not shown) and generates an image file.

  In step S <b> 450, the CPU 11 determines whether the image file generated by the MFP 51 has been received from the MFP 51. The image file may include various types of image data, for example, JPEG (Joint Photographic Experts Group) format image data. If no image file has been received (S450: NO), the process returns to S450, and if received (S450: YES), the process proceeds to S452.

  In S452, the CPU 11 determines whether the received image file is an image file compatible with Exif (Exchangeable Image File Format). An Exif-compatible image file is a file that can record various types of additional information (eg, type of image data, shooting date and time, etc.). If it is not an Exif-compatible image file (S452: NO), the flow ends. If it is an Exif-compatible image file (S452: YES), the flow proceeds to S454.

  In S454, the CPU 11 determines whether the type of the image file is a book file. This determination may be made, for example, based on whether or not information indicating that the document to be scanned is a book has been input by the user when an input of a scan execution command is received in step S446. In S <b> 456, the CPU 11 describes that it is a book file as additional information in the Exif-compatible image file. Then, the flow ends.

<Operation of viewer application>
Processing for displaying a plurality of images included in one image file using the viewer application 21a will be described with reference to FIG. When receiving an input of a user operation for starting the viewer application 21a via the button input unit 17, the CPU 11 starts the viewer application 21a. Then, the flow of FIG. 2 is started.

  In S302, the CPU 11 determines whether any one of the plurality of image files stored in the image file storage area 12b is selected as a display target image file (display target image file). . For example, an icon indicating each of the plurality of image files may be displayed on the panel 18 and it may be determined whether or not a touch input has been performed on one of the icons. If a display target image file has not been selected (S302: NO), the process returns to S302, and if selected (S302: YES), the process proceeds to S310.

  In S310, the CPU 11 sets the selected image page number to “1”. Accordingly, the first image in the plurality of images included in the display target image file is selected as the selection image G1 that is the display target image.

  In S312, the CPU 11 executes a book file determination process. The contents of the book file determination process will be described using the flow of FIG. The book file determination process is a process of determining whether or not the display target image file is a book file.

  In S410, the CPU 11 determines whether or not the format of the display target image file is an electronic book format. Examples of formats for electronic books include EPUB and XMDF (ever-eXtending Mobile Document Format). If the format is for an electronic book (S410: YES), it is determined that the image file is a book file, the process proceeds to S420, and the file type flag is set to “book file”. Then, the book file determination process ends.

  On the other hand, when the format of the display target image file is not the format of the electronic book (S410: NO), the process proceeds to S412 and the CPU 11 determines whether or not additional information based on Exif is added to the display target image file. . If additional information is not added (S412: NO), the process proceeds to S416, and if added (S412: YES), the process proceeds to S414. In S414, the CPU 11 reads additional information added to the display target image file. Then, it is determined whether or not the additional information includes information indicating that the image file is a book file. If information indicating that the file is a book file is included (S414: YES), it is determined that the image file is a book file, and the process proceeds to S420 to set the file type flag to “book file”. Then, the book file determination process ends.

  On the other hand, if the information indicating that the file is a book file is not included (S414: NO), the process proceeds to S416, and the CPU 11 determines that the size of the document used when generating the image included in the image file is It is determined whether it is A4 size or less. The document size determination process may be performed on any one of a plurality of images included in the image file. For example, the document size determination process may be performed on the first image in the image file.

  The document size determination process may be performed based on, for example, the resolution of image data and the number of pixels. As an example, a case where the short side of an image is X (pixel), the long side is Y (pixel), and the resolution of the image is a (dpi) (dots per inch) will be described. In this case, the short side length of the document is X / a (inch), and the long side length of the document is Y / a (inch). The short side length of the A4 size is about 8.27 (inch), and the long side length is about 11.69 (inch). Therefore, it is only necessary to determine whether the short side length and the long side length of the document are equal to or shorter than the A4 size short side length and the long side length. If the size of the document is A4 size or smaller (S416: YES), it is determined that the plurality of images included in the image file are in “spread relationship”, and the process proceeds to S420, and the file type flag is set to “book file”. To "". Then, the book file determination process ends.

  On the other hand, if it is larger than the A4 size (S416: NO), it is determined that the image file is a file other than a book file, and the process advances to S418 to set the file type flag to “other than a book file”. Then, the book file determination process ends.

  Returning to the flow of FIG. In S314, the CPU 11 determines whether or not the display target image file is a book file. Specifically, the file type flag is read and determined. If the display target image file is a book file (S314: YES), the process proceeds to S316.

  In S316, the CPU 11 determines whether or not the selected image G1 selected by the selected image page number is the first (first page) image in the image file. If it is not the first image (S316: NO), the process proceeds to S320.

  In S320, the CPU 11 displays the selected image G1 and the related image G2 on the panel 18 in a spread mode. The related image G2 is an image related to the selected image G1, and is an image in which the page order is continuous with the selected image G1. As shown in FIG. 11 and FIG. 13, the spread mode displays the selected image G1 on the panel 18 as an image of one of the left and right pages, and the related image G2 as an image of the other page of the left and right pages. 18 is displayed. FIG. 11 shows a display example when the selected image G1 and the related image G2 are displayed in a spread mode on the vertically oriented panel 18. FIG. 13 is a display example when the selected image G1 and the related image G2 are displayed in a spread mode on the horizontally oriented panel 18.

  In step S322, the CPU 11 determines whether a display page change operation (an operation for sending a page or an operation for returning a page) has been performed. The display page changing operation may be performed in response to receiving an input of a flick operation on the panel 18, for example. When the display page change operation is not performed (S322: NO), the process returns to S322, and when the display page change operation is performed (S322: YES), the process proceeds to S324. In S324, the CPU 11 executes display page change processing. Specifically, when sending a page, “2” is added to the current page number of the selected image page number. When returning the page, “2” is subtracted from the current page number of the selected image page number. Then, the process proceeds to S336.

  On the other hand, in S316, when the selected image G1 selected by the selected image page number is the first (first page) image in the image file (S316: YES), the process proceeds to S330. In S330, the CPU 11 displays only the selected image G1 on the panel 18 in a one-screen display mode different from the spread mode. The one-screen display mode is a mode in which only the selected image G1 is displayed on the panel 18 as shown in FIGS. In a book, the cover is in a one-screen display mode and is often spread out from the second page. Thus, the image of the first page is displayed in a one-screen display mode because it is a display form corresponding to a book. FIG. 12 is a display example when the selected image G1 is displayed on the vertically oriented panel 18 in a one-screen display mode. FIG. 14 is a display example when the selected image G1 is displayed in a one-screen display mode on the horizontally oriented panel 18.

  In S <b> 332, the CPU 11 determines whether a display page change operation has been performed. When the display page change operation is not performed (S332: NO), the process returns to S332, and when the display page change operation is performed (S332: YES), the process proceeds to S334. In S334, the CPU 11 executes display page change processing. Specifically, when sending a page, “1” is added to the current page number of the selected image page number. When returning the page, “1” is subtracted from the current page number of the selected image page number. Then, the process proceeds to S336.

  In S336, the CPU 11 determines whether or not an image corresponding to the selected image page number changed by the display page change operation exists in the image file. If it exists (S336: YES), the process returns to S316, and if it does not exist (S336: NO), the process proceeds to S338. In S338, the CPU 11 causes the panel 18 to display “It is the first page or the last page”. Then, the flow ends.

  On the other hand, when the display target image file is not a book file in S314 (S314: NO), the process proceeds to S350 (FIG. 3). In S350, the CPU 11 determines whether the orientation of the panel 18 of the mobile phone 10 is vertical or horizontal. Specifically, the CPU 11 acquires sensor information related to the tilt of the casing of the mobile phone 10 from the tilt sensor 29 using the API. Based on the sensor information, it is determined which direction the longer side of the panel 18 extends is closer to the vertical direction or the horizontal direction. When the orientation of the panel 18 is landscape orientation (S350: landscape orientation), the process proceeds to S352.

  In S352, the CPU 11 displays the selected image G1 and the related image G2 in a spread mode. In this case, as shown in the display example of FIG. 13, the selected image G1 and the related image G2 are displayed on the horizontally oriented panel 18.

  In S354, the CPU 11 determines whether or not a display page change operation (an operation for sending a page or an operation for returning a page) has been performed. In S356, the CPU 11 executes display page change processing. Note that the specific processing contents of S354 and S356 are the same as the respective processing contents of S322 and S324 described above, and a description thereof will be omitted.

  On the other hand, if it is determined in S350 that the orientation of the panel 18 is vertical (S350: vertical orientation), the process proceeds to S362. In S362, the CPU 11 displays only the selected image G1 in the one-screen display mode. In this case, only the selected image G1 is displayed on the vertically oriented panel 18, as shown in the display example of FIG. Further, since the selected image G1 is a portrait image, the selected image G1 is displayed on the vertical panel 18 (FIG. 12) as compared to the case where the selected image G1 is displayed on the horizontal panel 18 (FIG. 14). ) Can display the selected image G1 larger. In S364, the CPU 11 determines whether a display page change operation has been performed. In S366, the CPU 11 executes display page change processing. Note that the specific processing contents of S364 and S366 are the same as the respective processing contents of S332 and S334 described above, and a description thereof will be omitted.

  In S368, the CPU 11 determines whether or not an image corresponding to the selected image page number changed by the display page changing operation exists in the image file. If it exists (S368: YES), the process returns to S350, and if it does not exist (S368: NO), the process proceeds to S370. In S370, the CPU 11 causes the panel 18 to display “It is the first page or the last page”. Then, the flow ends.

<Effect>
The effect of the mobile phone 10 according to the first embodiment will be described. In the mobile phone 10 according to the first embodiment, when the display target image file is a book file (S314: YES), two images of the selected image G1 and the related image G2 are displayed on the panel 18 in a spread mode. (S320) (FIG. 11). When the display target image file is not a book file image file (S314: NO), one image of the selected image G1 can be displayed on the panel 18 in a one-screen display mode (S362) (FIG. 12). ). That is, the number of images displayed on the panel 18 can be automatically changed depending on whether or not the display target image file is a book file. As a result, it is possible to display a plurality of images on the panel 18 in a form that is most easily viewable, so that convenience for the user can be improved.

  In the mobile phone 10 according to the first embodiment, it is determined whether or not the display target image file is a book file based on the size of the document used when generating the image included in the display target image file. (S416). Thereby, it is possible to determine whether or not the display target image file is a book file by a simple process.

  In the mobile phone 10 according to the first embodiment, when the image file to be displayed is a book file (S314: YES), when displaying the image of the first page (S316: YES), one image of the first page Can be displayed on the panel 18 in a one-screen display mode (S330) (FIG. 12). When displaying the second and subsequent images (S316: NO), the two images of the selected image G1 and the related image G2 can be displayed on the panel 18 in a spread mode (S320) (FIG. 11). . When a portrait image is displayed on the vertically oriented panel 18, a single screen is displayed in a single screen display mode (FIG. 12) as compared to a case where two images are displayed in a spread mode (FIG. 11). ) Can display a larger image. As a result, it is possible to display the image of the first page that is not displayed in the spread mode and display two images displayed in the spread mode side by side.

  In the mobile phone 10 according to the first embodiment, even when the display target image file is not a book file (S314: NO), when the panel 18 is in the landscape orientation (S350: landscape orientation), the two images are arranged side by side.

In addition, since the structure of the mobile telephone 10 in 4th Embodiment is the same as that of the mobile telephone 10 in 1st Embodiment, description is abbreviate | omitted here.

  In step S <b> 702, the CPU 11 determines whether a display target image file has been selected. If no display target image file has been selected (S702: NO), the process returns to S702, and if selected (S702: YES), the process proceeds to S710. In S710, the CPU 11 sets the selected image page number to “1”. In S711, the CPU 11 executes a book file determination process. Note that the contents of the book file determination process performed in S711 are the same as the contents of S312 (FIG. 4), and thus detailed description thereof is omitted.

  In S712, the CPU 11 determines whether the display target image file is a book file based on the file type flag. If the display target image file is not a book file (S712: NO), the process proceeds to S740. In S740, the CPU 11 displays only the selected image G1 in a one-screen display mode. In step S742, the CPU 11 determines whether a display page change operation has been performed. In S744, the CPU 11 executes display page change processing. Then, the process proceeds to S750. Note that the specific processing contents of S740, S742, and S744 are the same as the respective processing contents of S330, S332, and S334 described above, and a description thereof will be omitted.

  On the other hand, when the display target image file is a book file (S712: YES), the process proceeds to S714. In S <b> 714, the CPU 11 performs an OCR (Optical Character Recognition) process on the selected image G <b> 1 selected by the selected image page number. In the OCR process, it is recognized whether the arrangement direction of the character strings included in the selected image G1 is vertical writing or horizontal writing. In the OCR process, the page number displayed in the selected image G1 is recognized. In addition, since the OCR processing method used conventionally may be used, description about the OCR processing content is abbreviate | omitted here.

  In S716 (FIG. 10), the CPU 11 determines whether the page number of the selected image G1 recognized by the OCR process is an odd number or an even number. If the page number of the selected image G1 is an even number (S716: even number), the process proceeds to S720. In S720, the CPU 11 determines whether the arrangement direction of the character strings included in the selected image G1 is vertical writing or horizontal writing based on the OCR processing result. If the arrangement direction of the character strings is vertical writing (S720: vertical writing), the process proceeds to S722.

  In S722, the CPU 11 displays the selected image G1 and the related image G2 on the panel 18 in a “right-bound spread mode”. At this time, the selected image G1 and the related image G2 are labeled in such a manner that the smaller one of the selected image G1 and the related image G2 is located on the right side with respect to the larger page number.

  Here, an example of a method for determining the smaller and larger page numbers of the selected image G1 and the related image G2 will be described. The first page is a cover page, and the second and subsequent pages are often spread pages. Of the two pages that are spread pages, the even page corresponds to the smaller page number, and the odd page has the page number. It is good to judge that it corresponds to the larger one.

  Therefore, in S722, the CPU 11 may display the selected image G1 of the even page (the page number is smaller) on the right side and display the related image G2 of the odd page (the page number is larger) on the left side.

  On the other hand, in S720, if the arrangement direction of the character strings is horizontal writing (S720: horizontal writing), the process proceeds to S724. In S724, the CPU 11 displays the selected image G1 and the related image G2 on the panel 18 in a “left binding spread mode”. At this time, the selected image G1 and the related image G2 are marked in such a manner that the smaller one of the selected image G1 and the related image G2 is located on the left side with respect to the larger page number. Specifically, the selected image G1 of the even page (the page number is smaller) is displayed on the left side, and the related image G2 of the odd page (the page number is larger) is displayed on the right side.

  If the page number of the selected image G1 recognized in the OCR process is an odd number in S716 (S716: odd number), the process proceeds to S730. In S730, the CPU 11 determines whether the arrangement direction of the character strings included in the selected image G1 is vertical writing or horizontal writing based on the OCR processing result. When the arrangement direction of the character strings is vertical writing (S730: vertical writing), the process proceeds to S732.

  In S732, the CPU 11 displays the selected image G1 and the related image G2 on the panel 18 in a “right-binding spread mode”. At this time, the selected image G1 and the related image G2 are labeled in such a manner that the smaller one of the selected image G1 and the related image G2 is located on the right side with respect to the larger page number. Specifically, the CPU 11 displays the related image G2 of the even page (the one with the smaller page number) on the right side and displays the selected image G1 of the odd page (the one with the larger page number) on the left side.

  On the other hand, if the arrangement direction of the character strings is horizontal writing in S730 (S730: horizontal writing), the process proceeds to S734. In S <b> 734, the CPU 11 displays the selected image G <b> 1 and the related image G <b> 2 on the panel 18 in the “left binding spread mode”. At this time, the selected image G1 and the related image G2 are marked in such a manner that the smaller one of the selected image G1 and the related image G2 is located on the left side with respect to the larger page number. Specifically, the related image G2 of the even page (the page number is smaller) is displayed on the left side, and the selected image G1 of the odd page (the page number is larger) is displayed on the right side.

  In step S <b> 736, the CPU 11 determines whether a display page change operation (page sending operation or page returning operation) has been performed. In S738, the CPU 11 executes display page change processing. Note that the specific processing contents of S736 and S738 are the same as the respective processing contents of S322 and S324 described above, and a description thereof will be omitted.

  In S750, the CPU 11 determines whether or not an image corresponding to the selected image page number changed by the display page changing operation exists in the image file. If it exists (S750: YES), the process returns to S716, and if it does not exist (S750: NO), the process proceeds to S752. In S752, the CPU 11 causes the panel 18 to display “It is the first page or the last page”. Then, the flow ends.

<Effect>
