Problems solved by technology

[0004] When the voice coil motor moves the lens, the electromagnetic force between the voice coil and the magnet needs to drive the lens, the carrier and the four pairs of voice coils or four pairs of magnets fixed on the carrier to move at the same time, and the load is relatively large, resulting in the anti-shake function of the voice coil motor. high power consumption

Embodiment Construction

[0063] The following embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0064] Embodiments of the present application provide a camera module and an electronic device using the camera module. The camera module uses a shape memory alloy (SMA) motor to drive the image sensor to move on the vertical plane of the optical axis of the lens, and realizes optical path offset compensation through the translation of the image sensor, so that the camera module has an optical anti-shake function. .

[0065] The SMA motor includes the upper part of the motor and a plurality of SMA wires connected to the upper part of the motor. The image sensor is fixed on the upper part of the motor. By controlling the electrical signals of the multiple SMA wires, the upper part of the motor is driven to carry the image sensor to translate, so the SMA motor has a simple structure, small volume. Since...

Abstract

The embodiment of the present application discloses a camera module, which includes a module bracket, a lens, an image sensor and an SMA motor that are stacked and installed inside the module bracket. The SMA motor is located on the light-emitting side of the lens, the image sensor is located between the lens and the SMA motor and is fixed to the SMA motor, and the SMA motor is used to drive the image sensor to move on the vertical plane of the optical axis of the lens. Electronic equipment. The above camera module drives the image sensor to move through the SMA motor to achieve optical anti-shake, and the power consumption of the camera module is low. The embodiments of the present application also provide an electronic device.

Description

technical field [0001] The embodiments of the present application relate to the technical field of photography, and in particular, to a camera module and an electronic device. Background technique [0002] With the increasingly powerful camera functions of smartphone cameras, optical image stabilization (OIS) has gradually become one of the main selling points and competitiveness of mobile phone cameras. The function of optical image stabilization is to perform real-time detection and feedback of mobile phone shake within a certain frequency and amplitude range when taking pictures and perform reverse compensation. Because the compensation is usually obtained by correcting the optical path through an optical lens (lens), it is better than using software algorithms. In terms of gain, the loss in image quality is very small, so the image quality is well guaranteed. [0003] At present, the commonly used optical anti-shake motor is mainly a voice coil motor (VCM). The voice co...
