摘要:
Disclosed is a camera module capable of overcoming a design limitation on a structure for auto-focusing and handshake compensation attributable to the thickness of the camera module provided in a small-sized camera device. The camera module includes a refractive unit including at least one lens, which has an optical axis oriented in a first direction, a lens case for supporting the refractive unit mounted thereto, a focusing-driving magnet secured to the lens case, a focusing-driving coil configured to accommodate at least a portion of the focusing-driving magnet inserted thereinto and to receive first current and generate driving force for allowing the focusing-driving magnet to perform first relative displacement in the first direction, a compensatory case configured to support the focusing-driving coil fixedly mounted thereto, and a focusing-sensing coil fixedly provided in the compensatory case and wherein second current is electromagnetically induced at the focusing-sensing coil by the first relative displacement.
