For example, the acceleration sensor 108 is configured so that the screen is always displayed in the correct orientation.

(Operation of the embodiment)
Hereinafter, the operation of the mobile terminal device 1 according to the present embodiment will be described in detail with reference to FIGS.

  The user performs a sliding operation while tracing the character string displayed on the screen of the display 11 (liquid crystal panel 11a) while touching the character string and the modification attribute detected via the touch sensor 12. When there is a designated input for character modification (step S101 “Yes”), the mobile terminal device 1 (CPU 100) first captures the character position (step S102). At this time, the CPU 100 may display a pop-up window showing a list of character modification items on the display 11 screen in order to prompt further character modification.

  Subsequently, the CPU 100 determines the input position (step S103). If the input position is the center of the character string (step S103 “center”), the CPU 100 executes a character modification process for adding a cancellation line to the character string. If it is the lower part (step S104 “lower part”), a character modification process for adding an underline to the character string is executed, and the processing result is output to the image processing unit 102 (step S105). That is, when the CPU 100 detects the touch position of the character string on the liquid crystal panel 11a and the slide operation simultaneously (in real time), the CPU 100 generates character modification information for adding an underline or a cancellation line to the character string.

  In determining the input position, the CPI 100 calculates character display position information and a character size in order to output the result of character modification processing to the display 11 (liquid crystal panel 11a) via the image processing unit 102. Output. Specifically, for example, the coordinates of the character base line (for example, the lower left of the character font) of the L line assigned to the liquid crystal panel 11a are (X, Y), the height of the character font is H, and the lower left position of the liquid crystal panel 11a. When the coordinates (0) are (0, 0) and the touch position coordinates of the liquid crystal panel 11a at the start of the slide operation are (Xt, Yt), the following conditions (1) to (3) are satisfied: It is determined that each slide operation has been performed.

That is,
・ If Y + 1/3 * H> Yt, Y ≦ Yt → Lower part of character ・ If Y + 1/3 * H <Yt, Y + 2/3 * H ≧ Yt → Center of character ・ Y + 2/3 * H <Yt, Y + H If ≧ Yt → upper part of character

  For example, as illustrated in FIG. 4A, the image processing unit 102 generates display information including a character string pattern with a cancellation line added when a slide operation is performed on the upper part of the character string. . As another example, when a slide operation is performed below the character string, display information including a character string pattern to which an underline is added as illustrated in FIG. 4B is generated. Display information generated by the image processing unit 102 is written in the built-in VRAM 102a. Subsequently, the display control unit 120 reads the display information from the VRAM 102a built in the image processing unit 102 in synchronization with the display timing of the display 11 (liquid crystal panel 11a), and outputs it to the display 11 (liquid crystal panel 11a). The desired display can be obtained. For example, when a strike operation is performed even though a slide operation is performed with the intention of displaying an underline, editing can be performed such as changing the character modification process depending on the UNDO or the end position of the slide operation, as will be described later. is there.

  For example, as shown in FIG. 5A, when a sliding operation is performed on an arbitrary character string while characters are being input to the liquid crystal panel 11a, the operation starts according to the height H of the character string. Character modification processing is executed. Here, since an operation has been performed on the central portion of the character string having a height H, a cancellation line is added. After the character-modified character string pattern is displayed, the CPU 100 displays, for example, a pop-up window whose example is shown in FIG. 5B and waits for pop-up item selection input (step S106). According to FIG. 5B, in addition to OK (confirmation) and UNDO (cancellation of the previous operation) as selection items, other character modifications such as Bold (bold), Underline (underline), and Hatching (hatching), etc. Items for are illustrated. If there is an item input (“Yes” at step S106), the CPU 100 executes further character modification processing according to the selected item, or operation confirmation or change processing (step S107). For example, when the Underline item is selected in the pop-up window, the cancellation line added to the character string selected by the previous slide operation is changed to an underline as shown in FIG.

  Finally, when there is a definite input operation (OK item selection) (step S108 “Yes”), the CPU 100 deletes the pop-up window as shown in the screen of FIG. Ends.

  In the mobile terminal device 1 according to the present embodiment, only the underline and the cancellation line are illustrated as the character modification processing. However, other than the character emphasis by hatching, bolts, shading, etc. Changes can be applied in the same manner. Further, not only the character modification process but also the deletion of character strings, the selection of homonyms in the kanji conversion process, and the like can be applied in the same manner.
