Abstract: Provided is an apparatus and a method for determining coordinates of an icon on a display screen of a mobile communication terminal. The apparatus includes a display unit displaying the icon selection screen including the at least one icon and icon regions including icons; a focusing determination unit determining a background color of the icon selection screen, comparing the current hue value for each pixel with a previous hue value for each pixel pre-stored, determining a focus color and a focus region of a focused icon region, and calculating center coordinates of the determined focus region; and a control unit judging whether a difference between the current hue value and the previous hue value is 0, and determining the pixels having a comparison result other than 0 as the pixels having the changed hue values.
