Abstract:
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.
Abstract:
Disclosed herein is an actuator for driving zoom lenses, where the zoom actuator comprises a first carrier having attached thereto a first lens and movable along an optical axis; a second carrier having attached thereto a second lens and being capable of moving along the optical axis and running anterior or posterior to the first carrier; a housing enclosing the first and second carriers; a first magnet attached to the first carrier; a second magnet attached to the second carrier; a first coil unit mounted to the housing and facing the first magnet; a second coil unit mounted to the housing and facing the second magnet; and a plurality of balls; with at least one of said plurality of balls positioned between the housing and the first carrier; and at least one of said plurality of balls positioned between the housing and the second carrier.
Abstract:
An apparatus for driving an optical-reflector includes a support frame having a groove line formed therein, an optical-reflector installed at the support frame to change a path of light input through an opening so that the light is put into a lens, a base frame having a guiding groove formed with a shape corresponding to the groove line, and a plurality of balls disposed between the groove line and the guiding groove so that the support frame and the base frame are kept in a spaced state, and a driving unit configured to move the support frame along a path corresponding to the groove line or the guiding groove.
Abstract:
A camera actuator includes: a first OIS carrier provided with first and second magnets and an image sensor, and moving in a first direction perpendicular to an optical axis direction; a first drive coil for moving the first OIS carrier in the first direction by generating an electromagnetic force on the first magnet; a second OIS carrier provided on the upper portion of the first OIS and moving in the optical axis direction and a second direction perpendicular to the first direction; a second drive coil for moving the second OIS carrier in the second direction by generating an electromagnetic force on the second magnet; and a support frame provided with the first and second drive coils and providing a moving space for the first and second OIS carriers.
