The character display control unit 102 corresponds to the display control unit 42 described above, and the selection unit 103 is a function exhibited by the control unit 45 described above.

  The storage unit 101 stores one character or character string as an enlargement target. The character display control unit 102 includes a target character display area A that displays one or more characters stored as an enlargement target in the storage unit 101, and a predetermined character out of one or more characters displayed in the target character display area A. An enlarged character display area B for enlarging and displaying one character at a predetermined magnification is generated, and the generated target character display area A and enlarged character display area B are displayed on the display unit 21.

  The selection unit 103 selects one character from among one or more characters displayed in the target character display area A. Specifically, the character string is scrolled by selecting the button X having the function of the selection unit 103 displayed on the display unit 21.

  Further, the character display control unit 102 enlarges one selected character among the one or more characters displayed in the target character display area A at a predetermined magnification, and displays the enlarged character in the enlarged character display area B. . The function of the character display control unit 102 is exhibited when a predetermined application (hereinafter referred to as a character enlargement application) is activated.

  Here, a specific example will be described. In the following, an example of enlarging and displaying the character string “display at the time of enlarging confirmation” is shown, and it is assumed that the character enlarging application is activated by an operation by the user. The storage unit 101 stores, for example, a character string “displayed at the time of enlargement confirmation” input by a user operation. The character display control unit 102 displays a character string stored as an enlargement target in the storage unit 101 in the target character display area A. At this time, as shown in FIG. 5A, the character display control unit 102 displays the first character of the character string in the target character display area A by performing reverse display in order to distinguish it from other characters.

  In addition, the character display control unit 102 displays a character (in the example illustrated in FIG. 5A, which is “expanded”) that is distinguished from other characters among the characters displayed in the target character display area A. The enlarged character display area B is enlarged and displayed at a predetermined magnification. In the example shown in FIG. 5, the predetermined magnification is a magnification that is about nine times as large as the character displayed in the target character display area A.

  When the button X displayed on the display unit 21 in FIG. 5A is selected, the selection display in the target character display area A moves from the character “enlarged” to the next character “large”. Along with this movement, the character display control unit 102 enlarges and displays the “Large” character in the enlarged character display area B, as shown in FIG. In addition, the character display control unit 102 sequentially switches characters to be selected and displayed in the target character display region A by appropriately selecting the button X, and the character newly selected by the switching is displayed in the enlarged character display region B. Zoom in. Further, when the “edit” button Y in FIGS. 5A and 5B is selected, the cellular phone device 1 can edit the character string displayed in the target character display area A. In addition, when the “end” button Z in FIGS. 5A and 5B is selected, the cellular phone device 1 ends the character enlargement application.

The designation unit 104 is a function exhibited by the control unit 45 described above. In such a configuration, the character display control unit 102 may display only characters of a predetermined number of strokes or more in the target character display area A among the character strings specified by the specifying unit 104. The mobile phone device 1 may be configured to include a stroke number setting unit that sets the stroke count. In the case of such a configuration, the character display control unit 102 displays in the target character display area A only characters that are equal to or larger than the number of strokes set according to the user's operation.

  For example, the character display control unit 102 selects a predetermined number of strokes (for example, 10 strokes) out of a character string (for example, a character string “the name of the flower is a rose”) whose range is designated on the Web screen by the designation unit 104. ) Only the above characters are displayed in the target character display area A. In this embodiment, the character display control unit 102 displays “rose” in the target character display area A. Further, the character display control unit 102 displays the character (“薔” or “rose”) selected and displayed in the target character display area A in an enlarged character display area B with a predetermined magnification.

  With this configuration, the mobile phone device 1 can display a target character in a considerably enlarged manner and ensure sufficient visibility when it is desired to check a character having a predetermined number of strokes or more. it can.

  Further, in the configuration in which the cellular phone device 1 includes the designation unit 104, the character display control unit 102 has a predetermined number of pixels that are necessary to configure a character in the character string designated by the designation unit 104. It may be configured to operate so as to display only characters that exceed the target character display area A.

  In general, in the mobile phone device 1, a character is constituted by a set of a plurality of pixels. In addition, as the number of pixels increases, it is difficult to see details in a small display, and it is difficult to recognize characters accurately. Therefore, the mobile phone device 1 can display a target character with a considerably enlarged size by extracting characters that exceed a predetermined number of pixels, and ensure sufficient visibility.

  Further, as shown in FIG. 4, the mobile phone device 1 may be configured to include an activation unit 105 (activation means). The activation unit 105 is a function exhibited by the control unit 45 described above.
