ABSTRACT:
A camera zoom device and method for a mobile communication terminal. The camera zoom device includes a zoom dial rotating about a rotation axis; a zoom dial rotation sensing unit for sensing a rotation angle of the zoom dial; a zoom controlling unit for determining a zoom direction (zoom-in or out) and a zoom magnification depending on the sensed rotation angle; and a zoom lens driving unit for driving a zoom lens unit depending on the zoom direction and the zoom magnification. The camera zoom device zooms in or out depending on the rotation angle of the zoom dial, thereby enabling a convenient and prompt camera zoom function, and preventing lens shaking that is commonly caused when the zoom function is performed by pressing keys.
