Abstract
An actuator for a camera module includes two or more detectable elements, the detectable elements are respectively disposed on a first and second surface of a lens barrel, an oscillating element including a first oscillation circuit unit that includes two or more oscillation circuits facing the first surface of the lens barrel, and a second oscillation circuit unit that includes two or more oscillation circuits facing the second surface of the lens barrel, and a determining device that calculates a position of the lens barrel in response to oscillation signals output from the oscillating element. The determining device is configured to calculate the position of the lens barrel based on determined frequencies of oscillation signals of the first oscillation circuit unit and the second oscillation circuit unit.
