Description

Image pickup device and camera lens hand shake prevention carrier module thereof

Technical Field

The present disclosure relates to a camera lens, and more particularly to a camera lens with two actuating members for directly driving the camera lens to improve compensation accuracy and a camera lens anti-shake table module thereof.

Background

People often hold a mobile phone or an image pickup device to take images so as to generate images by utilizing a lens and an image pickup module of the mobile phone or the image pickup device. However, when the mobile phone or the camera device is held, the hand can vibrate slightly unintentionally, so that the quality of the camera is affected. Therefore, the existing mobile phones or camera devices are provided with a hand shake prevention mechanism so as to compensate the hand shake of a user, thereby obtaining high-quality images.

The existing mode of preventing hand shake has a relative movement type, namely, the image sensor and the lens are relatively displaced to play a role of compensation. However, this compensation method of relative displacement generates a dark angle or offset at the periphery of the image due to the movement of the optical path, and the closer to the corner, the larger the offset of the image, so that this compensation method of relative displacement is generally suitable for applications with smaller compensation angles.

Another existing anti-shake mechanism is a tripod head type mechanism, which can realize large-angle image compensation by enabling the whole lens module to rotate relative to the image sensor to perform compensation. However, the existing tripod head type hand vibration prevention mechanism drives the whole lens module to rotate together, and the driving weight is large, so that the compensation cannot be performed rapidly, and the compensation effect is poor.
