Camera module for mobile communication device, mobile communication device using the same, and method for controlling the same

A mobile communication terminals comprising:

• a terminal housing having a signal input/output system, a display, a memory, a controller, and a mobile communication signal processor;
• a battery pack detachably mounted at the terminal housing;
• and
• a camera module including a camera housing mounted at the terminal housing, a lens provided in the camera housing, a means for elastically supporting the lens in the camera housing, and a lens transformer configured to move the lens by generating an attractive force or repulsive force when power is supplied.

A method for controlling a camera module for a mobile communication terminal, comprising steps of:

• (a) supplying an initial voltage to a lens transformer and thereby moving a lens of the camera module, the camera module including means for elastically supporting the lens in the camera housing;
• (b) determining whether a focal point of a subject projected on a camera sensor of the camera module is wrong after the lens is moved in response to the initial voltage;
• and
• (c) automatically and continuously adjusting a strength of a voltage supplied to the lens transformer until a correct focal point is established.

A method of assembling a camera module usable in a communication device, comprising:

• providing a camera housing including first, second and third housing parts;
• inserting a portion of a transformer within an upper portion of the second housing part;
• inserting a portion of the third housing part within the upper portion of the second housing part;
• suspending a lens within the first housing part placed on the third housing part with a means for elastically supporting the lens in the camera housing;
• and
• inserting a potion of an image processor within a lower portion of the second housing part.

A controllable camera module for a mobile communication terminal, comprising:

• means for supplying an initial voltage to a lens transformer and thereby moving a lens of the camera module;
• means for elastically supporting the lens in a camera housing;
• means for determining whether a focal point of a subject projected on a camera sensor of the camera module is wrong after the lens is moved in response to the initial voltage;
• and
• means for automatically and continuously adjusting a strength of a voltage supplied to the lens transformer until a correct focal point is established.
