Abstract:
The embodiment relates to an image stabilization device and a camera module including the same.
The image stabilization device according to the embodiment includes: a first prism for changing a path of a light beam; a second prism disposed below the first prism and changing a path of light beam emitted from the first prism; an image stabilization control unit for controlling a shape of the second prism including a coil part and a magnet part.
The first prism may be disposed inside the image stabilization control unit. The second prism may be a variable wedge prism. The image stabilization control unit may control the path of the light beam by changing the shape of the second prism through the magnet part.
