Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0015] see figure 1 , the camera module 100 provided by the first embodiment of the present invention, which includes a lens base 10, a lens barrel 20, at least one lens 30 accommodated in the lens barrel 20, an image set at the bottom of the lens base 10 The sensor 40 and an optical compensation unit 50 , the optical compensation unit 50 is disposed in the mirror holder 10 and located between the lens 30 and the image sensor 40 .

[0016] The mirror base 10 has a top circular accommodating cavity 13 and a bottom rectangular accommodating cavity 14 . The lens barrel 20 is accommodated in the top circular accommodation cavity 13 . The image sensor 40 is accommodated in the bottom square cavity 14 . The inner wall of the top accommodating cavity 13 of the mirror base 10 has an internal thread, the outer wall of the lens barrel 20 has an outer thread, and the...

Abstract

The invention provides a camera module, which comprises at least one lens, an image sensor and an optical compensating unit, wherein the optical compensating unit is arranged between the lens and the image sensor, is used for regulating light entering the image sensor and comprises a first transmission plate, a second transmission plate and at least one electrostrictive element which is clamped between the first light transmission plate and the second light transmission plate; an enclosed cavity is formed between the first and second light transmission plates and the electrostrictive element and is filled with liquid the refractive index of which is basically the same as that of the first and second light transmission plates; and when voltage applied on the at least one electrostrictive element is changed, the at least one electrostrictive element generates deformation, so that the relative positions of the first and second light transmission plates are changed.

Description

technical field [0001] The invention relates to a camera module, in particular to a camera module with shake correction function. Background technique [0002] With the development of camera technology, camera modules are widely used in camera devices for various purposes. The combination of camera modules and various portable electronic devices such as mobile phones, video cameras, computers, etc. is favored by many consumers. . [0003] However, when the camera is held, hand shakes may cause blurred images in the photographed or video images. This is because during the exposure time, the orientation of the lens module relative to the object to be photographed is constantly changing, and the image of the object imaged on the image sensor is also constantly changing. Blurring occurs when the data is superimposed. [0004] The usual shake correction method is to move or tilt the lens or image sensor in the lens, so that during the shooting process, the shaking caused by th...
