Provided is a camera device, including: a camera lens having an optical axis; a lens driving mechanism configured to drive the camera lens to move along the optical axis; an image stabilization mechanism including a movable frame, and an image sensor chip and a first flexible substrate arranged at the movable frame. The image stabilization mechanism is movable in a plane of the image sensor chip, and the first flexible substrate is made of liquid crystal polymer. The use of the LCP substrate for the first flexible substrate can greatly reduce elasticity of existing flexible substrates due to polyimide, so it has frequency characteristics similar to other rigid bodies and system resonance is not easily generated during movement of the image stabilization mechanism. Therefore, more precise servo control of the movable frame can achieved, thereby enabling camera device to have higher-quality hand-shake correction control and image stabilization control.
