Fuente: Wipo "Sensorization" Embodiments of this application disclose a three-axis optical image stabilization system and method based on image sensor displacement, and an apparatus. First shake data in a first direction, second shake data in a second direction, and third shake data in a third direction are collected by using a sensor. Then, a controller obtains a displacement amount of an image sensor in a first axial direction, a displacement amount of the image sensor in a second axial direction, and a displacement amount of the image sensor in a third axial direction based on the first shake data, the second shake data, and the third shake data. Finally, a driver chip drives, by using an optical image stabilization motor based on the displacement amount of the image sensor in the first axial direction, the displacement amount of the image sensor in the second axial direction, and the displacement amount of the image sensor in the third axial direction, the image sensor to shift in the first axial direction, the second axial direction, and the third axial direction, to implement optical image stabilization in three directions: a pitch direction, a yaw direction, and a roll direction.
