Patent ID: 8542988

Claim:
An image stabilizing apparatus comprising: a base; a first frame that is movably coupled to the base in a first direction; a first vibration axis that extends along the first direction to movably support the first frame in the first direction; a first rail that movably couples the first frame to the base; the first frame comprises a first slider that is extended from an outer portion of the first frame to contact the first vibration axis to be movable along the first vibration axis; a first vibration unit that includes a piezoelectric device coupled to an end of the first vibration axis and vibrates the first vibration axis upon receiving a first electrical signal; a first sensing unit that senses a position variation of the first frame; a second frame that is movably coupled to the first frame in a second direction that crosses the first direction; a lens coupled to the second frame; a second vibration axis that is disposed on the first frame and extended along the second direction to movably support the second frame along the second direction; the second frame comprises a second slider that is extended from an outer portion of the second frame to contact the second vibration axis to be movable along the second vibration axis; a second vibration unit that includes a piezoelectric device coupled to an end of the first vibration axis and vibrates the second vibration axis upon receiving a second electrical signal; and a second sensing unit that senses a position variation of the second frame.
