Description
Technical Field
The invention relates to the technical field of camera modules, in particular to an optical anti-shake camera module and an optical anti-shake method.
Background
With the rapid development of the smart phone industry, the requirements of people on the imaging effect of the mobile phone camera are gradually improved, and compared with the traditional camera system, the mobile phone camera module (Cell phone Camera Module, CCM) is widely applied to various new-generation portable camera equipment due to the advantages of miniaturization, low power consumption, low cost, high image quality and the like.
Currently, the CCM includes a lens unit, an IR (infrared filter), an image sensor, a flexible circuit board or a printed circuit board, and a connector connected to a main board of a mobile phone.
The common automatic focusing camera module is characterized in that a focusing motor drives a lens to move up and down in the direction of an optical axis, so that an automatic focusing function is realized. When photographing or shooting, the camera cannot be kept absolutely stable due to shake of a person or other reasons, so that a certain deviation of an optical path is generated, at the moment, the focusing and the light incoming quantity of the lens are influenced, and the quality of an image acquired by the shooting module is further influenced. Such optical path deflection generally occurs in a direction perpendicular to the optical axis, and the autofocus motor can only drive the lens to move in the optical axis direction, so that the problem caused by such optical path deflection cannot be solved. An optical anti-shake actuator is added on the basis of an automatic focusing motor, a lens is driven to move in two directions perpendicular to an optical axis or is driven to move obliquely around the optical axis, the deflection of the lens can be compensated, a camera is helped to obtain better image quality, and the camera module is called as an optical anti-shake camera module.
The existing mature optical anti-shake scheme of the camera module is mostly made in a focusing motor, and the lens is translated or inclined to compensate shake caused by hand vibration or other reasons, and the compensation mode is limited by the size of the focusing motor and the weight of the optical lens, so that anti-shake compensation with a large stroke/large compensation angle cannot be formed. The lens translation scheme is superior to the lens tilting scheme, the problem of anti-shake failure can appear in the lens tilting scheme under the condition that the lens is too large and too heavy, and meanwhile, the lens tilting scheme can lead to the phenomenon that four corners become dark or fuzzy after compensation due to the light path problem, so that customer experience is affected.
Moreover, since the fixed-focus camera module is not provided with a driving motor, the conventional lens translation type or tilting type optical anti-shake scheme cannot be used for realizing the optical anti-shake function.
Therefore, the optical anti-shake scheme capable of realizing large stroke, large compensation angle and wider universality is provided, and has great significance in the field.
