The camera sensor is assumed to be a charge coupled device (CCD) sensor, and the signal processor may be implemented by a digital signal processor (DSP). In addition, the camera sensor and the signal processor may be integrally implemented or may be separately implemented.

The controller 40 controls the overall operation of the mobile communication terminal according to the embodiment of the present invention. In particular, the controller 40 enlarges the size of a predetermined character input to the key input unit 10 and displays it on the display unit 20 based on a user request such as a menu key input through the key input unit 10. Switch to silver character input mode. The predetermined characters include Korean, English alphabets, special characters, and Arabic numerals.

When the mobile communication terminal switches to the silver character input mode, the controller 40 separately creates an enlargement window at a predetermined position (for example, the lower right side of the basic character display window) of the display unit 20. The enlarged window may be implemented as a pop-up window that enlarges (eg, doubles) the size of a predetermined character input to the key input unit 10, and the pop-up window is provided on the key input unit 10. It is preferable to display the input characters until the input characters are completed.

Thereafter, the controller 40 controls to display the predetermined characters on the basic character display window of the display unit 20 and the generated enlarged window when the predetermined character is input through the key input unit 10 in the silver character input mode.

On the other hand, when the mobile communication terminal is switched to the silver character input mode, the control unit 40 is a consonant provided in the key input unit 10 to distinguish between the key assigned to the Korean consonant and the key assigned to the vowel as a backlight color; It is also possible to control the LED 11 or the vowel LED 13 to convert the default backlight color.

That is, if the default backlight color of the mobile communication terminal is blue, the user converts the backlight color of the key to which the Korean consonant is assigned to red or converts the backlight color of the key to which the vowel is assigned to red to allow the user to assign the key to which the consonant is assigned. And vowels make it easy to determine the assigned key.

The memory 50 may be configured as a program memory, a data memory, and the like to store various kinds of information necessary for controlling the operation of the mobile communication terminal according to the present invention. In addition, the memory 50 stores various characters required when the user inputs a character in the character input mode of the mobile communication terminal.

3 is a flowchart illustrating an input character display process of a mobile communication terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 3, the mobile communication terminal checks whether there is a text input mode request from the user (S110). The text input mode request of the user may be a menu key input or a voice input.

When the user inputs a text input mode request, the mobile communication terminal checks whether to select a silver text input mode to enlarge and display the size of a predetermined text input to the mobile communication terminal (S120).

If the user does not select the silver character input mode, the mobile communication terminal performs a general character input mode (S130).

If the silver character input mode is selected by the user in step S120, the mobile communication terminal switches to the silver character input mode and performs this operation (S140).

When the mobile communication terminal is switched to the silver character input mode, a predetermined character input in the silver character input mode at a predetermined position of a basic character display window (that is, the display unit 20) displaying various display information output from the mobile communication terminal. A magnification window is displayed to enlarge and display the size (S150). The enlarged window is preferably implemented in a pop-up form, and is preferably generated at a lower right portion or a center portion of the basic text display window.

The mobile communication terminal converts and outputs a backlight color of a key to which a Korean consonant is assigned or a vowel to which a Korean consonant is allocated among various keys included in the keypad (ie, the key input unit 10) during the silver character input mode (S160). This is to easily distinguish between consonants and vowels to be input when the user inputs a character.

For example, if the basic backlight color of the keys provided in the keypad is blue, the mobile communication terminal outputs by converting the backlight color of the key to which the Korean consonant is assigned to red or converts the backlight color of the key to which the vowel is assigned to red. By outputting, the user can easily determine the key assigned to the consonant and the key assigned to the vowel.

The mobile communication terminal checks whether a predetermined character is input based on the user's key operation (S170).

When a predetermined character is input, the mobile communication terminal displays the input predetermined character on the basic text display window and the generated enlarged window (ie, a popup window) (S180). In this case, the mobile communication terminal may generate the enlargement window and display the inputted text while the predetermined text is input. In addition, when a predetermined character is input, the mobile communication terminal may display the input predetermined character on the basic text display window and the generated enlargement window, and simultaneously output the input text as a voice.

On the other hand, when a predetermined character is input in step S180, the mobile communication terminal converts a backlight color of a key to which a vowel is assigned or the inputted character is a vowel of Korean when the inputted character is a consonant of Korean. In this case, the backlight color of the key to which the consonants are assigned may be converted.

For example, it is assumed that a user of the mobile communication terminal whose backlight color of the keys provided in the key input unit 10 is blue inputs the character “Lim”.

When the user first inputs the consonant "", the mobile terminal recognizes that the input "a" is the consonant, and facilitates the user to assign a key to which the next vowel to be assigned is assigned (ie, "|"). The vowel converts the backlight color of the assigned keys to red to make it easier to determine. Subsequently, when the "ㅣ" key is input, the mobile terminal recognizes that the input character "ㅣ" is a vowel and displays the letter "ki", and then the user can easily determine the next consonant "ㅁ" key. To do this, the backlight color of the keys to which the consonants are assigned is converted to red.

As described above, when the predetermined character is input, the mobile communication terminal converts the backlight color of the key to which the vowel is assigned, or when the input character is the vowel of the Korean character. By converting the backlight color, users with low vision or the elderly can see exactly what they type.

Referring to Figs. 4 (a) to 4 (c), Fig. 4 (a) shows "Do you want to execute the silver character input mode?" A screen for selecting whether or not to execute the silver character input mode is shown.

When the user selects the silver character input mode as shown in FIG. 4 (a), the mobile communication terminal has a size of a predetermined character input in the silver character input mode at a predetermined position of the basic character display window as shown in FIG. 4 (b). Displays the screen on which the enlarged window to enlarge / display is created. In the screen of FIG. 4 (b), the items / a / are located at the bottom of the screen, and Korean / A / are English uppercase letters, / a / is an English lowercase letter, and / special / is an item for inputting a special character.

When the character "a" is input based on the user's key operation on the screen of FIG. 4 (b), the mobile communication terminal generates the input character "a" as shown in the screen of FIG. Display on the enlarged window 22, respectively. In this case, it is preferable that the mobile communication terminal displays the letter “a” displayed on the enlarged window 22 in a larger size (eg, twice) than the letter “a” displayed on the basic text display window. And it is preferable that the enlarged window 22 displays the input characters until the character which a user wants to input is completed.

Meanwhile. When the character "ㅏ" is input based on the user's key operation on the screen of FIG. 4 (c) in which the character "a" is displayed, the mobile communication terminal merges the input character "ㅏ" with the previously input character "a". One character "a" is displayed on the basic character display window and the created enlarged window 22 as shown in the screen of FIG.

In the above description of the present invention, a specific example has been described with respect to Korean character input, but various modifications such as input of an English alphabet, special characters, and Arabic numerals can be implemented without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined not only by the claims but also by the equivalents of the claims.

As described above, the present invention may enlarge and display the size of the text input to the mobile communication terminal through a separate pop-up window and simultaneously output the input text as a voice so that the user can easily check the small letters and It can also be used effectively for language learning.

In addition, elderly people or people with poor eyesight can check the characters they input accurately, so that the user can conveniently use the mobile communication terminal.
