Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a portable terminal keypad change system according to a first embodiment of the present invention.

The portable terminal keypad change system according to the first embodiment of the present invention includes a content server 100 and a portable terminal 300.

The content server 100 provides content for a keypad applicable to the display-based keypad of the terminal, and the portable terminal 300 is equipped with a display-based keypad for receiving the content for the keypad and applying it to the keypad. Preferably, the display-based keypad can be equipped with a touch screen panel, it may be implemented as a separate LCD for each key.

The content server 100 includes a memory unit 110, an area separator 130, a color determiner 150, and a character color expression unit 170.

The memory unit 110 stores the contents for the keypad applicable to the display-based keypad. Preferably, the memory unit 110 includes the arrangement information of one or more terminal keypads and the form of a letter assigned to an area for each key corresponding to each key of the display-based keypad. It is also possible to store keypad information including information about (eg, typeface). Here, 'one or more terminal keypads' means all terminal keypads that are commercialized and used by users (of course, an appropriate number (type) of terminal keypads selected in consideration of realistic terminal specifications), and 'terminal keypads'. 'Arrangement information' means layout information (also referred to as configuration / arrangement / structure / shape information) of the keypad structure for applying the contents for the keypad to the key area.

The area divider 130 divides the content for the keypad applicable to the display-based keypad into areas for each key of the keypad. Here, the content for the keypad may be a background image or a predetermined key event applicable to the display-based keypad, and the key-by-key event may include a key-specific image and a key-specific sound effect applicable to each key of the display-based keypad.

The color determination unit 150 determines the representative color for each area of the content for the keypad divided into areas for each key. The method of determining the representative color by the color determination unit 150 may include a method of taking an average value of RGB units of a predetermined number of pixels in a key area, a method of taking an RGB value having the highest occurrence frequency among the pixel units, and the like. Various methods can be taken.

The text color expression unit 170 selects a color contrasted with the representative color of the key area by the color determination unit 150, and applies the color to the text assigned to each key area. Preferably, the character color expression unit 170 selects the complementary color for the representative color of the key area by applying the color to each character of the key according to the 'color ring' stored separately in the content server. The text color expression unit 170 may apply a complementary color to a letter assigned to each key region by using a function defined based on a 'color ring'. Here, the complementary color means a color that gives a clear impression when the color is placed in a position facing each other in the 'color ring', and the letter refers to all symbol systems that can be expressed on languages, symbols, and other keys. .

A more detailed description of the complementary color applied to the representative color determination of the color determination unit 150 and the character of the key area of the character color expression unit 170 will be described later with reference to FIG. 3.

As described above, the content server 100 may synthesize a character obtained by applying a color contrasted with the content for the keypad and the representative color of the key area, to the terminal by synthesizing the text for the key area. However, in some cases, synthesizing the text to which the representative color of the keypad contents and the key area is performed may be performed in the portable terminal 100.

Although not shown in the drawing, the content server 100 may match and store characters for the keypad synthesized in the memory unit 110 and characters for which the complementary color is applied to the area allocated for each key by the customer and the terminal.

The portable terminal 300 analyzes the text for which the complementary color is applied to the key area provided from the content server 100 and the synthesized content for the keypad and applies it to the divided area of the display based keypad. Here, the content analysis for the keypad is prepared (or waiting) to decompose the data constituting the content for the keypad into meaningful elements and to apply (or display) to the area of each key of the keypad divided by the area classification module 431 to be described later. ) Means to be in a state.
