Camera system with auto-focus function and control method thereof
A camera system is provided. The camera system includes a first housing, a lens module accommodated in an inner space of the first housing, a support panel engaged to a side surface of the first housing, a magnet which is mounted on the lens module and confronts the support panel, and a drive portion which is arranged on the support panel and linearly moves the lens module in a direction of an optical axis, wherein the drive portion comprises a hall sensor portion for detecting displacement of the lens module, a coil fixed on a circuit board of the drive portion, and a controller for controlling current applied to the coil according to output of the hall sensor portion, and wherein the controller and the hall sensor portion are integrated in one chip.
The present invention discloses a drive control apparatus of a camera module and a method of controlling camera module drive. The drive control apparatus of the camera module according to an embodiment of the present invention comprises: a lens module movable along an optical axis; a first and a second stoppers defining maximum moving section of the lens module; and a controller for determining an available moving section by applying a first determined correction value to the maximum moving section so as to make the lens module to move between locations spaced from the first and second stoppers with a predetermined distance. According to the present invention, it is advantageously possible to reduce the electric current consumption when performing auto-focusing function.
A linear vibration generating apparatus employed in a portable terminal is provided. The linear vibration generating apparatus includes a bracket, a coil inserted into the bracket, a stator inserted into the bracket and including a central yoke concentrically fixed to an interior space of the coil, a vibrator including a permanent magnet disposed to surround an outer periphery of the coil, and a resilient body fixed to the stator to support the vibrator.
