Abstract

The invention relates to a correction method, a correction device, electronic equipment and a voice coil motor. The method comprises the steps: obtaining a detection image of a test graphic card whena lens is detected to move to a preset position; determining a current inclination amount of the lens according to the detection image; and adjusting the energization current of the correction coil according to an inclination calibration function and the current inclination amount, so that the correction coil controls the lens to move to compensate the current inclination amount. According to thecorrection method, the target electrifying current corresponding to the correction coil is obtained through the preset inclination calibration function and the current inclination amount, the target electrifying current of the correction coil is used for controlling the lens to move to compensate the current inclination amount of the lens, and the problem that the current inclination amount of thelens at the target position influences image collection is solved.

Description

technical field

[0001] The present application relates to the field of imaging, in particular to a calibration method, device, electronic equipment and voice coil motor. Background technique

[0002] With the development of imaging technology, people are more and more accustomed to taking images or videos and recording various information through image acquisition devices such as cameras on electronic devices. Under the action of the focusing coil in the voice coil motor, the camera moves to the target focusing position to focus and collect images.

[0003] However, the lens will be tilted to different degrees during the movement controlled by the voice coil motor, which affects the acquisition of images at the target focus position. Contents of the invention

[0004] Embodiments of the present application provide a correction method, device, electronic equipment, and voice coil motor, which can compensate for an offset generated by a lens during movement.
