(Operation)
Hereinafter, the operation of the image display apparatus according to the embodiment of the present invention will be described with reference to the drawings.

  The electronic page data 11A is periodically received by the communication unit 10 from the electronic page data distribution server 2 via the Internet 3 every morning, for example, and stored in the storage unit 11.

  The electronic paper surface data 11A stored in the storage unit 11 instructs the operation signal analysis unit 14 to read the electronic paper surface data 11A to the electronic paper data management unit 12 when the user performs a display operation on the input unit 15. The electronic paper surface data management unit 12 causes the display unit 20 to display the read electronic paper surface data 11A and displays the electronic paper surface 200A on the display screen 20A.

  FIG. 8 is a schematic diagram illustrating an operation example of the image display apparatus according to the embodiment of the present invention.

  When the electronic paper page data management unit 12 receives a movement, enlargement, or reduction operation signal from the input unit after the electronic paper page 200A is displayed, the electronic paper page list display 200B, the electronic page page display 200C, and the like shown in FIGS. The display is switched to one of the electronic paper article displays 200D and 200E.

  The electronic paper list display 200B is a list display mode, the electronic paper page display 200C is a page display mode, the electronic paper article displays 200D and 200E are article display modes, and the electronic paper data management unit 12 is, for example, the electronic paper page 200A. When an operation signal for movement is input after display, the display is switched to the page display mode, and the selection display 22, display designation character string 23A, and enlarged display area 23B are displayed.

  The display designated character string 23A moves a character string to be selected based on a movement operation signal (for example, the left and right keys of the remote controller 15A), and the enlarged display area 23B enlarges the character string selected by the display designated character string 23A. indicate. Note that the character line is displayed with the line break omitted in the enlarged display, but the line break position 230 may not be displayed. Further, the enlarged display area 23B is not limited to a single line display, and may be a display over a plurality of lines. The above description is the same in the enlarged display area 24B, and the enlarged display area may be displayed in the electronic paper list display 200B.

  For example, when a movement operation signal (up / down key of the remote controller 15A) is input, the selection display 21 or 22 is moved to select a page or an article, respectively.

  Further, for example, when a reduction operation signal (return key of the remote controller 15A) is input after displaying the electronic paper page display 200C, the electronic paper page list display 200B is displayed by switching to the list display mode, and an enlargement operation signal ( When the determination key of the remote controller 15A is input, the article display mode is switched to enlarge the article selected by the selection display 22, and the electronic paper article display 200D or 200E is displayed.

  FIG. 9 is a flowchart showing an operation example of the image display apparatus according to the embodiment of the present invention.

  First, when an operation is input to the remote controller 15A (S1; Yes), the operation signal analysis unit 14 checks whether or not the operation is a movement operation. If the operation is a movement operation (S2; Yes), The operation signal control unit 13 instructs the electronic page data management unit 12 to move the display designation character string 23A or 24A (left / right key of the remote control 15A) or the selection display 21 or 22 (up / down key of the remote control 15A) (S3). ).

  If the operation input to the remote controller 15A is not a movement operation (S2; No), it is confirmed whether or not the operation is a reduction operation. If the operation is a reduction operation (S4; Yes), the operation signal control unit 13 Then, the display mode of the electronic page data management unit 12 is confirmed, and the electronic page enlargement / reduction unit 16 is instructed to switch the display mode to the reduced display mode (S5).

  When the operation input to the remote controller 15A is not a reduction operation (S4; No), that is, when the operation is an enlargement operation, the operation signal control unit 13 checks the display mode of the electronic page data management unit 12. If it is not in the page display mode (S6; No), that is, if it is in the list display mode, the electronic page enlargement / reduction unit 16 is instructed to switch to the enlarged page display mode (S7).

  When the page display mode is selected (S6; Yes), the electronic paper layout extraction unit 17 detects the size of the article selected by the selection display 22, and the article size is larger than the threshold (S8; No). For example, when the size of the article is larger than one article, the image superimposing unit 19 superimposes the display designation character string 24A and the enlarged display region 24B and displays the electronic paper article display 200D on the display unit 20 (S9). .

  When the article size is equal to or smaller than the threshold (S8; Yes), for example, when the article size is one article or less, the image superimposing unit 19 does not superimpose the display designation character string 24A and the enlarged display area 24B. The electronic paper article display 200E is displayed on the display unit 20 (S10).

(Effect of embodiment)
According to the above-described embodiment, since the electronic paper data is selected and displayed from the list display mode, the page display mode, or the article display mode with a simple key operation of the remote controller 15A, the electronic paper data can be easily reduced in scale desired by the user. Data can be displayed. In addition, when it is difficult for the user to read the character size of the displayed article text, it is displayed in the enlarged display area 23B or 24B by being designated by the display designation character string 23A or 24A. Can be easily searched.

  In this embodiment, a newspaper is shown as an example of the contents of electronic paper data. However, the present invention can be similarly applied to electronic paper data that requires a layout and includes text, images, illustrations, and the like. . In the present embodiment, the main purpose of browsing electronic paper has been described. However, the present invention may be used for the purpose of searching for necessary information.
