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.

In an embodiment, when a sleep mode is turned off, if vibration less than a limit value occurs, the sleep mode is turned on and a hand shake correction unit is turned off so that power consumption may be reduced. Moreover, when the sleep mode is turned on, if vibration greater than a limit value occurs, the sleep mode is turned off and the hand shake correction unit is turned on so that an image blur does not occur. In another embodiment, when the sleep mode is turned off, if vibration less than a limit value occurs, the hand shake correction unit is turned on in the state where the sleep mode is turned on and a HPF is turned on so that an image blur is prevented from occurring due to a shock caused by pushing a release button or shock caused by opening or closing a shutter.
