In exemplary embodiments of the present invention, other attribute information of the remaining GUI elements can be connected to and stored in a pattern image of a ‘wave pattern’, and attribute information of the remaining GUI elements of each of all pattern images can be connected and stored. Further, an attribute information combination of a plurality of GUI elements and attribute information of the remaining GUI elements can be connected and stored. For example, a title/low end color of a black color, title/low end character color of a white color, main character color of a white color, selection area color of a cyan color, a selection area character color of a yellow color, and an icon kind of a house shape can be connected to a combination of a pattern image of a ‘wave pattern’ and a background screen color of a ‘blue color’ and they can be stored. FIG. 3 is a flowchart illustrating a method of setting a theme according to a first exemplary embodiment of the present invention.

At step (305), the controller 160 determines that a theme setting menu is selected by the user using the input unit 140. The theme setting menu can be included in a main menu of a mobile terminal and/or can also be included in a user setting menu. When the controller 160 determines a selection instruction of a theme setting menu, the controller 160 causes display unit 150 to display lower-level menus of the theme setting menu. In the present exemplary embodiment, a lower-level menu of the theme setting menu includes a pattern image theme setting menu, preset theme setting menu, picture image theme setting menu, and effect image theme setting menu. In the first exemplary embodiment of the present invention, a pattern image theme setting menu is selected.

At step (310), the controller 160 determines that a pattern image theme setting menu is selected by the user using the input unit 140.

FIG. 4

At step (315), if a pattern image theme setting menu is selected, the controller 160 extracts a plurality of pattern images stored in the storage unit 130 and controls the display unit 150 to display the extracted pattern images. In the present invention, a ‘pattern image’ comprises an image having a predetermined shape stored at a production time point of a mobile terminal. The pattern image may not include a color as a pattern form image of black and white and may be a picture form image including a color. In the present exemplary embodiment, the pattern image may be received from the outside through the RF unit 110 and stored in the storage unit 130.

FIG. 4
b illustrates a display screen for displaying pattern images stored in the mobile terminal.

At step (320), the controller 160 determines that one of a plurality of pattern images displayed in the display unit 150 is selected by the user using the input unit 140 (320).

FIG. 4
b illustrates a display screen for selecting a pattern image of a ‘wave pattern’.

At step (325), the controller 160 extracts attribute information of GUI elements stored to connect to the selected pattern image from the storage unit 130.

In the first exemplary embodiment of the present invention, attribute information of GUI elements composing a ‘theme’ corresponds to a pattern image kind, background screen color, main character color, title/low end area color, title/low end character color, selection area (focus area) color, and selection area character color, and the controller 160 extracts attribute information of the remaining GUI elements connected to a specific pattern image kind from the storage unit 130. For example, when a pattern image of a wave pattern and a background color of a sky blue color, main character color of a green color, title/low end area color of a blue color, title/low end character color of a yellow color, selection area color of a yellow color, and selection area character color of an orange color are connected and stored, the controller 160 extracts attribute information of a GUI element stored to connect to a pattern image of the wave pattern from the storage unit 130.

In the present exemplary embodiment, an attribute information combination of a plurality of GUI elements and attribute information of the remaining GUI elements among GUI elements composing a theme are connected and stored.

In this particular case, the controller 160 extracts attribute information of a plurality of GUI elements selected by the user and attribute information of the remaining GUI elements connected thereto from the storage unit 130. For example, when a combination of a pattern image of a ‘wave pattern’ and a background screen color of a ‘sky blue’ color; and a main character color of a green color, title/low end area color of a blue color, title/low end character color of a yellow color, selection area color of a yellow color, and selection area character color of an orange color are stored to connect, if the user selects a pattern image of a ‘wave pattern’ and a background screen color of a ‘sky blue’ color, the controller 160 extracts a main character color of a green color, title/low end area color of a blue color, title/low end character color of a yellow color, selection area color of a yellow color, and selection area character color of an orange color from the storage unit 130.

In the present exemplary embodiment, the quantity of GUI elements in which the user can select attribute information can be changed. For example, when the entire quantity of GUI elements composing a theme is “8”, the user can set the quantity of GUI element for selecting attribute information to “1” or a plural number. In the present exemplary embodiment, a menu for setting the quantity of GUI elements for selecting attribute information can be included in an auxiliary menu of a theme setting menu, and the user can select the quantity of GUI elements for selecting attribute information within a range of from 1 to the entire quantity of GUI elements composing a theme. A menu for setting the quantity of GUI elements for selecting attribute information may be formed with a menu that can individually select a GUI element to select attribute information of GUI elements composing a theme.

At step (330), the controller 160 composes a theme based on the extracted attribute information and controls the display unit 150 to display the composed theme.

FIG. 4
c illustrates a display screen for displaying a theme composed by the controller 160.

At step (335), the controller 160 determines whether a setting completion key is input by the user using the input unit 140. When the user requests storage of the theme displayed at step 330, a setting completion key is input that signals same to the controller 160.

At step (340), if a setting completion key is input, the controller 160 stores a composed theme in the storage unit 130. When storing a theme, the controller 160 controls the display unit 150 to display a message for requesting an input of a theme title. The controller 160 forms themes that are set by the user as a list and stores the themes in the storage unit 130. The themes stored in the storage unit 130 can be loaded by a user's instruction and can be transmitted to another party through wireless communication or short range communication using protocols such as Bluetooth, Zigbee, and IrDA, just to name a few possibilities. If a setting completion key is not input at step 335, then at step (345), the controller 160 determines whether or not an editing key is input by the user using the input unit 140. When the user wants to edit attribute information of the GUI element instead of storing the theme displayed at step 330, an editing key is input.

At step (350), if an editing key is input, the controller 160 controls the display unit 150 to display a menu for changing attribute information of a GUI element. A menu for changing attribute information of a GUI element can be formed in one step or a plurality of steps. For example, the controller 160 controls the display unit 150 to display step-by-step menus for changing a background screen color, main character color, title/low end area color, title/low end character color, selection area (focus) color, and selection area character color, and the user can gradually change from the background screen color to the selection area character color. In the present exemplary embodiment, a menu of each step can be formed with a menu for changing a hue, brightness, and opacity. In the present exemplary embodiment, a menu for changing a hue, brightness, and opacity can be formed in a control bar form.

FIG. 4
d illustrates a menu for changing attribute information of a GUI element according to an exemplary embodiment of the present invention.

The background color can be changed via a color adjustment bar (preferably positioned at a lower part of the display screen).

At step (355), the controller 160 controls the display unit 150 to display a theme according to the changed attribute information. For example, when the user inputs an instruction for changing a background screen color from a sky blue color to a yellow color through the input unit 140, the controller 160 controls the display unit 150 to change and display the background color from a sky blue color to a yellow color. In the present exemplary embodiment, the controller 160 extracts the pattern image selected at step 320 and an attribute information combination of a GUI element changed by the user at step 345 and attribute information of the remaining GUI elements connected thereto from the storage unit 130, composes a theme, and controls the display unit 150 to display the composed theme. For example, when a combination of a pattern image of a ‘wave pattern’ and a background screen color of a ‘yellow’ color and a main character color of a red color, title/low end area color of an orange color, title/low end character color of a yellow color, selection area color of a yellow color, and selection area character color of a orange color are stored to connect, the controller 160 extracts the connection information from the storage unit 130, composes a theme, and controls the display unit 150 to display the composed theme. The user can change attribute information of the remaining GUI element step-by-step, and the controller 160 extracts a combination of attribute information of the changed GUI element and attribute information of the remaining GUI elements other than the changed GUI element connected thereto from the storage unit 130.

FIG. 4
e illustrates an example of a theme setting display screen of another form in the first exemplary embodiment of the present invention.

If a pattern image theme setting menu is selected, the controller 160 extracts attribute information of the remaining GUI elements connected to all pattern images from the storage unit 130 and controls the display unit 150 to display a preview image of a theme formed with a first pattern image and attribute information of the remaining GUI elements connected thereto.

In a display screen of FIG. 4e, an upper part represents a preview image of a theme formed with attribute information of the remaining GUI elements connected to a first pattern image (wave pattern) and a lower part represents a menu for selecting a pattern image and a menu for selecting a background color. When a background color connected to a pattern image of a wave pattern corresponds to a sky blue color, the controller 160 controls the display unit 150 to display a color chip to position at a sky blue color in a menu for changing a background color. The user requests storage of a particular theme displayed on a preview screen preferably by activating a setting completion key. When the user tries to change a pattern image, the user can change a pattern image using a pattern image selection menu positioned at a lower part of a display screen. When the user changes the pattern image to a second pattern image, the controller 160 controls the display unit 150 to display a preview image of a theme formed with a second pattern image and attribute information of the remaining GUI elements connected thereto. The background color can be changed using a background screen color change menu and can sequentially change a main character color, title/low end area color, title/low end character color, selection area (focus area) color, and selection area character color using a ‘previous’ or ‘next’ menu. In the first exemplary embodiment of the present invention, the user can compose a theme by only setting attribute information of some GUI elements including a pattern image, and can more conveniently compose a theme by changing additionally GUI elements in the composed theme.

FIG. 5 is a flowchart illustrating a method of setting a theme according to a second exemplary embodiment of the present invention.

The controller 160 determines that a theme setting menu is selected by the user using the input unit 140 (505). When the controller 160 determines an input of a theme setting menu, the controller 160 controls the display unit 150 to display lower-level menus of the theme setting menu. In the second exemplary embodiment of the present invention, a case of selecting a preset theme setting menu of theme setting lower-level menus is described.

At step (510), the controller 160 determines that a preset theme setting menu is selected by the user using the input unit 140.

FIG. 6
