Problems solved by technology

[0004] When the movement is severe or the stability of the auto focus (AF) direction of the voice coil motor is poor, the mobile phone lens will resonate with the accelerated movement in the AF direction (z-axis), which will lead to a series of effect problems, such as High-frequency stretching and shaking, sharpness changes between frames, image distortion, etc.

Abstract

The present application provides a control method, a voice coil motor, a lens module, and an electronic device. The control method includes: the electronic device determines the automatic zoom magnification of the camera; when the automatic zoom magnification is greater than or equal to a preset magnification threshold, the electronic device Setting the current phase angle of the voice coil motor as a first current phase angle; when the automatic zoom magnification is less than the preset magnification threshold, the electronic device sets the current phase angle of the voice coil motor as a second current phase angle; wherein, The first phase angle is smaller than the second phase angle. The embodiment of the present application helps to balance image effects and audio effects during video shooting.

Description

[0001] This application is a divisional application of an invention application with a filing date of March 25, 2020, a Chinese application number of 202010220523.2, and an invention title of "A Control Method, Voice Coil Motor, Lens Module, and Electronic Equipment". technical field [0002] The present application relates to the field of terminals, and more specifically, to a control method, a voice coil motor, a lens module and electronic equipment. Background technique [0003] High-power optical zoom has always been the development trend of smart phone cameras, but due to the trend of thinner and lighter smart phones, the traditional lens module structure will not be able to meet the requirements of high-power optical zoom. Therefore, periscope lenses have moved towards the stage of mobile phone cameras. Long-distance zooming is possible. Existing periscope camera modules usually have the function of optical image stabilization (OIS), so as to improve the quality of pho...
