As shown in FIG. 3 transmission, first, the main control unit 23 to read the document data corresponding from the document information storage unit 11 controls the document information reading section 18 to an instruction from the user, the layout generating unit 19 let (S1). Incidentally, may document information reading section 18 so as to appropriately read out document data from the document information storage unit 11 in accordance with the processing speed of the layout generating unit 19, the document data by the document information reading section 18 read buffer (shown not) may be caused to output the layout generating unit 19 via the.

The main control unit 23 controls the layout generating unit 19, in advance that have been set display conditions and document data inputted from the document information reading section 18 (character size, number, condition such as the size of the display screen) preparative on the basis to generate layout information showing a layout of a time of displaying an image corresponding to the document data on the display unit 14, and stores the generated layout information in the layout storage unit 16 (S2).

The main control unit 23 controls the display image generating unit 20, and displays an image corresponding to the document data based on the layout information and the browsing positional information stored in the layout memory 16 on the display unit 14 to generate display image data for displays by outputting to the display unit 14 (S3). Note that the viewing position information, page to be displayed in the document data is information indicating a display start position in the page. The browsing positional information, so the user sets may be specified each time, the location is stored the locations has been completed previously viewed if a document data seen before as browsing positional information it may be. In addition, for example, if there is no instruction and past browsing history to specify the viewing start position from the user, it may be displayed from the beginning point of the first page of the document data.

Thereafter, the main control unit 23, display transition operation from a user to determine whether or not the input (S4). Here, the display transition operation, the display in the page change operation for changing the page to be displayed (for example next page for shifting to turn operation, such as a page designation operation shifts to the specified page), or the page object moving operation point (e.g., line feed operation, such as scrolling operation), and the like.

When the display transition operation from the user is determined to have been input in S4, the main control unit 23 controls the display image generating unit 20 returns to the processing of S3, and the layout information stored in the layout memory 16 It generates display image data to be displayed on the display unit 14 based on the browsing positional information corresponding to the display transition operation, and displays and outputs the display unit 14.

On the other hand, if the display transition operation from the user is determined not to be input in the S4, the main control unit 23, zoom operation from the user (magnification adjustment operation) is equal to or has been performed (S5). If it is determined that zooming operation is not performed, the main control unit 23 proceeds to the processing in S12 to be described later.

On the other hand, if it is determined that the zooming operation is performed, the main control unit 23 controls the magnification calculator 21, the magnification ratio (enlargement ratio or reduction ratio) in response to a user operation and display start coordinates of the preview image It is calculated, and stores the magnification ratio and display start coordinates calculated magnification storage section 17 (S6). The main control unit 23 controls the display image generating unit 20, based on the magnification ratio and display start coordinates calculated by the magnification calculator 21 to generate a preview image, preview image generated on the display unit 14 It is displayed by the output (S7).

Specifically, magnification calculator 21, variable during the magnification adjustment operation is being carried out, continuously variable ratio based on the amount of movement of the user's finger in pinch-in operation or pinch-out operation (or a predetermined time intervals (for example, 0.1 per second) calculated) sequentially updates the scaling factor that is stored in the variable rate memory 17. In performing magnification adjustment operation by the operation means other than pinch-in operation or pinch-out operation may be calculated magnification in the calculation method in accordance with the operating method.

Further, magnification calculator 21, as shown in FIGS. 1 and 4, zooming operation (zoom ratio adjustment operation) is the upper left corner (the document being displayed in the display image displayed just before the start beginning of the string) sets the display position of the preview image to be placed in the upper left corner of the preview image (the beginning of the string in the preview image), and calculates the display start coordinates in. In the example shown in FIGS. 1 and 4, although to display the preview image on the entire area of ​​the display screen is not limited thereto, may be to display a preview image on a part of the display screen. The shape of the display area of ​​the preview image is not limited to a rectangle, for example, it may be a circle or an ellipse.

Thereafter, the main control unit 23 determines whether the user has performed a magnification determining operation (S8). In the present embodiment, after the pinch-in operation or pinch-out operation, it is determined that the magnification ratio determined operation has been performed when the two fingers of the user is away from the display screen. However, not limited thereto, and may be performed magnification determination operation by the user operating a predetermined button or the like.

When the magnification determination operation is determined not to take place in S8, the main control unit 23 continues the generation and display of a preview image returns to the process of S6.

On the other hand, if the magnification determination operation is determined to have been carried out in S8, the main control unit 23 controls the character size calculating unit 22, is stored in the variable rate memory 17 are magnification and zooming operation at the time to calculate the character size after scaling (after the layout change) according to the previous character size is performed (S9).
