Image stabilizing apparatus

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.
