Abstract
An imaging device includes a housing, a lens unit, a detection unit, a central processing unit and a driving unit. The lens unit is configured for moving between a first position where the lens unit is received in the housing, and a second position where the lens unit extends from the housing. The detection unit is configured for detecting a current acceleration of the imaging device. The central processing unit is configured for receiving the current acceleration and generating a low driving voltage value if the current acceleration is smaller than a predetermined value and a high driving voltage value if the current acceleration is equal to or greater than the predetermined value. The driving unit is configured for receiving the generated driving voltage value from the central processing unit and retracting the lens unit from the second position to the first position based on the driving voltage.
