Abstract
An actuator of a camera module includes: driving wires to drive a lens barrel in a direction perpendicular to an optical axis; a driver to provide a driving signal in the form of a pulse to the driving wires; and a controller to generate a control signal based on a target position of the lens barrel and a present position of the lens barrel, to control the driver, and to generate resistance offsets between the driving wires based on resistance slope of each of the driving wires.
Claims16
An actuator of a camera module, comprising:
- driving wires configured to drive a lens barrel in a direction perpendicular to an optical axis;
- a driver configured to provide a driving signal in the form of a pulse to the driving wires;
- and
- a controller configured to generate a control signal, based on a target position of the lens barrel and a present position of the lens barrel, to control the driver, and to generate resistance offsets between the driving wires based on a resistance slope of each of the driving wires.

- driving wires configured to drive a lens barrel in a direction perpendicular to an optical axis;
- a driver configured to provide a driving signal in the form of a pulse to the driving wires;
- and
- a controller configured to generate a control signal based on a target position of the lens barrel and a present position of the lens barrel to control the driver,
- wherein the controller is configured to use one driving wire having a shortest linear region among the driving wires as a reference driving wire to control the remaining driving wires.
