The partial enlarged screen 562 is a screen that displays an enlarged portion of the document displayed on the entire display screen 560 centered on the loupe image 561. As described with reference to FIG. 3, the partial enlarged screen 562 displays an image of a portion surrounded by a frame 201 that is a part of the frame 200 indicating the entire document. Further, the position where the loupe image 561 is displayed corresponds to the position of the center point 201A in the frame 200 of FIG. In the display 150, the entire display screen 560 is displayed so as not to overlap the partial enlarged screen 562.

  When the display processing unit 111 displays the screen 509 on the display 150 by the process of S11, the position of the center point 201A is a predetermined position in the document to be displayed, such as the center of the frame 200, for example.

  In the present embodiment, the entire display screen 560 is displayed above the partial enlarged screen 562, but the relative positional relationship between these screens is not limited to this. That is, the entire display screen 560 may be displayed below the partial enlarged screen 562, or may be displayed side by side with the partial enlarged screen 562 in the left-right direction.

  Here, referring to FIG. 5 again, when the up key 121A, the down key 121B, the left key 121C or the right key 121D is operated in a state where the screen 509 is displayed, after the processing of S11, the user performs S12. In S13, the mobile phone 100 that has been waiting for the input determines that an operation for moving the part to be displayed on the partial enlarged screen 562 has been performed, and shifts the process to S14.

  In S14, the display processing unit 111 moves the position of the center point 201A by a predetermined amount in a direction corresponding to the key determined to have been operated in S13, so that a partial enlarged screen in the document image is displayed. The part displayed at 562 is changed, and the process returns to S12.

  In this embodiment, the document information includes text information, and an example is shown in which the enlarged display is performed on the partial enlargement screen 562 at an enlargement magnification determined based on the number of input lines. The enlarged display made by the present invention is not limited to this. In the portable information device of the present invention, whether the document information includes text information or not, instead of the user specifying the number of lines, the user can display the partial enlarged screen 562 in the document information. It is also possible to input a target width (a width in a direction (specific direction) intersecting with a direction scrolled by automatic scroll control). In such a case, in the portable information device, an enlargement magnification to be displayed on the partial enlarged screen 562 is determined so that an image having the width is displayed on the entire partial enlarged screen 562 based on the input width.

  Referring to FIG. 17 again, function display fields 558 and 539 are further displayed on screen 509. In the function display column 539, characters “submenu” are displayed. This indicates that a function for displaying a submenu screen (see FIG. 20) described later is assigned to the function key 122C.

  In the function display field 558, characters “End” are displayed. This means that the function for ending the process of displaying the entire display screen 560 and the partial enlarged screen 562 on the display 150 as shown in FIG. 17 is assigned to the function key 122A. However, as will be described later, when the display is automatically scrolled on the partial enlarged screen 562 (when the automatic scroll control is executed), the character “end” is displayed on the display 150 as in FIG. Is displayed, and the function key 122A corresponding to the function display field 558 is assigned a function for ending automatic scrolling in the partial enlarged screen 562.

  FIG. 20 shows a screen 510 displayed on the display 150 when the function key 122C is operated while the screen 509 is displayed. On the screen 510, a file name display field 540 is displayed. Note that a submenu screen 555 is displayed on the screen 510 so as to overlap the entire display screen 560 and the partial enlarged screen 562. In the submenu screen 555, names (menus) of a plurality of functions from “screen reduction” to “button operation list” are listed in the vertical direction. However, the menu displayed on submenu screen 555 is partially different from the menu displayed on submenu screen 550. In addition, on the submenu screen 555, a cursor 556 is displayed so as to cover the selected menu. Further, the screen 510 displays a function display field 557 for displaying a function “decision” assigned to the function key 122A.

  Here, referring to FIG. 5 again, function key 122A is operated in a state where cursor 556 is displayed so as to cover the menu of “screen reduction”, “screen enlargement” or “line number designation” on submenu screen 555. Then, the display processing unit 111 determines in S15 that an operation for changing the enlargement magnification of the display on the partial enlargement screen 562 has been performed, and in S16, performs processing for changing such enlargement magnification. Execute and return to S12.

  When the function key 122A is operated in a state where the cursor 556 is displayed so as to cover the menu “automatic scroll” on the submenu screen 555, the display processing unit 111 executes automatic scrolling in S17. In step S18, automatic scrolling is started, and the process returns to step S12. The automatic scrolling is a control for automatically and continuously scrolling the display on the partial enlarged screen 562.

  When the automatic scrolling is started, the display is continuously scrolled from left to right on the partial enlarged screen 562 until the automatic scrolling is stopped in S20. When the display on the partial enlarged screen 562 moves to the right end of the document, an image including the left end of the document is displayed again on the partial enlarged screen 562. Scroll continuously from right to right. Note that the display position of the loupe image 561 is changed on the entire display screen 560 in response to the scroll display on the partial enlarged screen 562. Thus, even if the scroll display is continued on the partial enlarged screen 562, the user views the position of the loupe image 561 on the whole display screen 560, thereby displaying the image displayed on the whole display screen 560 on the partial enlarged screen 562. It is possible to easily recognize which part of the is enlarged.

  When the automatic scrolling is started, the display processing unit 111 performs the automatic scrolling process shown in FIG. 18 in parallel with other processes until the automatic scrolling is finished. The contents of the automatic scroll process will be described with further reference to FIG. FIG. 19 is a diagram for explaining how the document stored in the document storage unit 117 is displayed on the entire display screen 560 and the partial enlarged screen 562, as in FIG. 3. In FIG. 19, as in FIG. 3, an image corresponding to the entire document and displayed on the entire display screen 560 is surrounded by a frame 200, and is displayed on the partial enlarged screen 562 in the frame 200. The portion is surrounded by a frame 201, and the center of the frame 201 is a center point 201A.

  In the automatic scroll process, first, the display processing unit 111 moves the coordinates of the center point 201A to the right by a predetermined amount in S181. As a result, the positional relationship between the frame 200 and the frame 201 is changed from that shown in FIG. 19A to that shown in FIG. 19B, for example.

  In step S <b> 182, the display processing unit 111 determines whether the area to be displayed on the partial enlarged screen 562 is positioned at the right end of the document. Specifically, this determination is made based on whether or not the frame 201 is positioned at the right end of the frame 200. If it is determined that it is not yet positioned at the right end, the display processing unit 111 advances the processing to S184.

  On the other hand, as shown in FIG. 19C, if it is determined that the display processing unit 111 is positioned at the right end, the display processing unit 111 displays an area to be displayed on the partial enlarged screen 562 in S183 as shown in FIG. Is moved to the left end of the document, and the process proceeds to S184.

  In S184, the display processing unit 111 determines whether or not a predetermined time has elapsed since the last time the coordinate of the center point was moved in S181, and returns to S181 when it is determined that it has elapsed.

  When automatic scrolling is performed, the display 150 including the function display field 558 is displayed in the same manner as in FIG. If function key 122A corresponding to function display field 558 is operated while automatic scrolling is being performed, display processing unit 111 determines in S19 that an operation for ending automatic scrolling has been performed. In S20, the automatic scrolling is stopped, and the process returns to S12. When the automatic scrolling is stopped, the loupe image 561 is stopped and displayed on the entire display screen 560, and the scroll display continuously performed on the partial enlarged screen 562 is also stopped.

  If the function key 122A corresponding to the function display field 558 is operated when automatic scrolling is not performed, the display processing unit 111 performs an operation for ending the enlarged display of a part of the document in S21. In step S22, a screen showing only the entire document such as the screen 504 in FIG. 10 is displayed on the display 150, and the process returns to step S4.

  FIG. 6 is a flowchart of a subroutine of the process of changing the display enlargement magnification on the partial enlargement screen 562 (enlargement screen magnification changing process) in S16 of FIG. Hereinafter, with reference to FIG. 6 and FIG. 20 to FIG. 23, the contents of the process of changing the display magnification on the partial enlarged screen 562 will be described.

  When the enlargement screen magnification changing process is started, first, the display processing unit 111 determines whether or not the user desires to specify the number of rows in S161. The number of lines referred to here is the number of lines (number of characters in the vertical direction) of the document displayed on the partial enlarged screen 562. Note that the number of rows referred to here can be said to be a direction perpendicular to the scroll direction (left-right direction), for example.

  In the enlargement screen magnification changing process, the function key 122A is operated with the cursor 556 displayed on the submenu screen 555 so as to cover the menu “screen reduction”, “screen enlargement”, or “line number designation”. In response to The determination in S161 is made for the operation at this time. Specifically, if the function key 122A is operated with the cursor 556 displayed on the submenu screen 555 so as to cover the menu “number of rows”, the display processing unit 111 displays the number of rows from the user. Is determined to be input, and the process proceeds to S162. On the other hand, in the submenu screen 555, if the function key 122A is operated in a state where the cursor 556 is displayed so as to cover the menu “screen reduction” or “screen enlargement”, the display processing unit 111 performs the operation from the user. It is determined that the information desired to specify the number has not been input, and the process proceeds to S165.

  In S162, the display processing unit 111 displays the screen 511 shown in FIG. 21 on the display 150, and accepts the input of the number of rows from the user. On the screen 511, a file name display field 540 is displayed. On the screen 511, a line number designation screen 570 is displayed so as to overlap with the entire display screen 560 and the partial enlarged screen 562. On the line number designation screen 570, a line number input field 571 for inputting the number of lines designated by the user is displayed. In the line number input field 571, a number corresponding to the number of lines is input. The numbers in the line number input field 571 can be changed as appropriate by operating the up key 121A, the down key 121B, or the 12 key 124 including the numeric keypad. The screen 511 displays a function display field 572 for displaying a function “OK” assigned to the function key 122A. When the function key 122A is operated while the screen 511 is displayed, the number of lines displayed in the line number input column 571 at that time is input to the mobile phone 100. In response to this, the display processing unit 111 advances the process to S163.

  In S163, the display processing unit 111 calculates an enlargement magnification on the partial enlarged screen 562 for displaying the text of the input line number on the partial enlarged screen 562 for the document to be displayed. Here, the enlargement ratio is calculated by calculating the size of character information (such as the number of fonts) to be displayed on the partial enlarged screen from the number of input lines and the vertical size of the partial enlarged screen 562. Based on.

  When the enlargement magnification is calculated in S163, the display processing unit 111 changes the enlargement magnification in the partial enlargement screen 562 to the calculated magnification in S164, and returns.

  As an example in which the enlargement magnification on the partial enlargement screen 562 is changed, FIG. 22 shows a case where the magnification is lowered and FIG. 23 shows a case where the magnification is made higher than that shown in FIG.

  22 shows a screen 512 displayed on the display 150, and FIG. 23 shows a screen 513 displayed on the display 150. On the screens 512 and 513, an entire display screen 560, a partial enlarged screen 562, a file name display column 540, and function display columns 558 and 539 are displayed, respectively, and on each of the entire display screens 560, a loupe image 561 is displayed. Is displayed.

  Referring to FIGS. 17, 22, and 23, on screen 509, three lines of characters are displayed on partial enlarged screen 562 in the vertical direction. On the screen 512, the partial enlarged screen 562 displays nine lines of characters in the vertical direction. On the screen 513, one line of characters is displayed on the partial enlarged screen 562 in the vertical direction.

  On the other hand, in S165, the display processing unit 111 changes the enlargement magnification of the display on the partial enlargement screen 562 to a predetermined magnification, and returns. In S165, if the enlargement screen magnification changing process is started on the submenu screen 555 based on the menu “screen reduction”, the enlargement magnification is more constant than the previous enlargement magnification. If the magnification is low and the operation is started based on the menu “enlarge screen”, the magnification is higher by a certain magnification than the previous magnification.

  In the present embodiment described above, the scroll direction at the time of automatic scrolling on the partial enlargement screen 562 is the left-right direction, and the number of lines specified on the screen 511 is the vertical direction. The invention is not limited to this. The scroll direction may be the vertical direction (up and down direction), and the number of lines specified by the user may be the number of lines in the horizontal direction (left and right direction).

  Further, the processing for accepting the input of the number of lines as shown in FIG. 21 in the present embodiment described above may not be executed depending on the type of document displayed on the display 150. That is, for example, when the type of document displayed on the display 150 does not include text information, the display processing unit 111 refers to “line number designation” on the submenu screen 555 shown in FIG. Control may be performed so that the cursor 556 cannot be put on the menu.

  Furthermore, in the present embodiment, the scroll direction and the direction in which the number of lines specified are arranged are described as being different, but they may be the same. That is, on the partial enlargement screen, the enlargement magnification may be determined based on the number of characters in the left-right direction specified by the user while scrolling in the left-right direction by automatic scrolling.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
