Abstract

The invention discloses a control method and device, electronic equipment and a readable storage medium, and belongs to the technical field of electronic equipment. In the embodiment of the invention, when a camera module and a motor in the electronic equipment are both in a working state, a first vibration signal is acquired through a vibration signal sensor; and when the first frequency spectrum information obtained by the first vibration signal contains a frequency component equal to the self-resonant frequency of the camera module, changing the vibration frequency of the motor, so that the changed vibration frequency of the motor is different from the self-resonant frequency of the camera module. In this way, the phenomenon that the motor resonates with the shooting module when the motor vibrates in the working state can be avoided, then the problems that due to the resonance phenomenon, focusing is unstable when a user shoots, and a shot picture shakes are solved, the shooting stability is improved, and the user experience is improved.

Description

technical field [0001] The present application belongs to the technical field of electronic equipment, and in particular relates to a control method and device, electronic equipment and a readable storage medium. Background technique [0002] With the development of electronic equipment, camera modules have become standard components of electronic equipment. Such as figure 1 As shown, the camera module 100 mainly includes a lens 101 . In order to realize the focusing function of taking pictures, the camera module 100 generally also includes a coil 102 for controlling the movement of the lens 101 . The way in which the coil 102 controls the movement of the lens 101 is generally: after the coil 102 is energized, the coil 102 will be affected by the Ampere force in the magnetic field formed by the external magnet 103 , and then the movement of the lens 101 will be controlled under the effect of the Ampere force. The camera module 100 uses a unidirectional power supply, so th...
