Abstract:
An actuator for optical image stabilization includes: a fixed frame defining an internal space; a movable frame accommodated in the fixed frame and movable relative to the fixed frame; a first driver to provide driving force to the movable frame; a sensor substrate including a moving portion coupled to the movable frame and movable with the movable frame; an image sensor disposed in the sensor substrate and including an imaging surface oriented toward a first direction; and a base spaced apart from the image sensor. The base includes a first plate facing the image sensor and a second plate surrounding an external periphery of the first plate, and the first plate and the second plate are formed of different materials.
