Camera module actuator for optical image stabilization with movable image sensor

A camera module comprising:

• a housing having an internal space;
• a lens module, accommodated in the internal space, disposed to be movable in an optical axis direction;
• a fixed frame fixedly disposed on the housing;
• a moving frame configured to move in directions perpendicular to an optical axis relative to the fixed frame, rotate about the optical axis, and press against the fixed frame;
• a first ball member disposed between the fixed frame and the moving frame;
• guide grooves disposed, respectively, in opposing surfaces of the fixed frame and the moving frame facing each other in an optical axis direction;
• a first driver, disposed on the moving frame and the fixed frame, configured to provide a driving force to the moving frame;
• and
• a sensor substrate comprising a moving part, coupled to the moving frame and on which an image sensor is disposed, and a fixed part coupled to the fixed frame.

A camera module comprising:

• a lens module comprising one lens disposed in a lens barrel;
• a first actuator, configured for optical image stabilization, comprising:
• a fixed frame;
• a moving frame, accommodated in the fixed frame, configured to linearly and rotatably move about an optical axis;
• a first ball member disposed between the fixed frame and the moving frame;
• guide grooves disposed, respectively, in opposing surfaces of the fixed frame and the moving frame facing each other in the optical axis direction;
• a first driver, disposed on the moving frame and the fixed frame, configured to drive the moving frame;
• magnetic bodies configured to generate an attractive force between the fixed frame and the first driver;
• a sensor substrate having a portion movably coupled to the moving frame and another portion fixedly coupled to the fixed frame;
• and
• an image sensor disposed on the portion of the sensor substrate;
• and
• a second actuator, coupled to the first actuator, configured for focus the lens module on an optical axis direction.
