Abstract: A position detecting apparatus includes: a driver that moves a moving body having a lens mounted thereon, a first sensor and a second sensor respectively mounted on the moving body, a displacement detection pattern unit that reflects light emitted by the first or second sensors, and a controller that controls the first sensor and the second sensor to be alternately turned on to emit light, and if the light reflected by the displacement detection pattern unit is sensed, the controller detects a position of the lens based on sensing results, where the controller determines a period in which the first sensor is turned on and a period in which the second sensor is turned on based on an intersection point of a signal waveform sensed by the first sensor and a signal waveform sensed by the second sensor. Accordingly, power consumption of the position detecting apparatus can be reduced.

Abstract: An apparatus for adjusting a position of an optical element is disclosed. The apparatus includes: a support; a movement unit for supporting an optical element and being movable relative to the support; a magnet unit; a coil unit for generating a magnetic force for moving the movement unit when an electrical signal is applied; a sensor unit disposed in a position corresponding to the magnet unit for detecting a relative position of the movement unit with respect to the support; a locking unit for limiting or allowing movement of the movement unit; and a controlling unit connected to the coil unit for controlling the coil unit and determining whether the movement unit is in a state where movement of the movement unit is limited by the locking unit based on a signal output from the sensor unit.
