The present application provides a focus correction method and device, which relate to the technical field of lens control. The focus correction method includes: by controlling the drive motor to move to a preset position, obtain the forward definition, forward position, reverse sharpness and reverse position, and according to the forward definition, forward position, reverse The definition and reverse position are calculated to obtain the correction parameters; finally, during the movement of the drive motor, the distance moved by the drive motor is corrected according to the correction parameters, and the distance moved by the drive motor is corrected according to the correction parameters by obtaining the correction parameters The correction is made to make the lens focus accurately, and it can make the lens focus accurately and synchronously during the zooming process, avoiding the problem that the lens cannot focus accurately in the related technology, resulting in unclear shooting scenes, and reducing the error when the drive motor moves. The drive motor can precisely control the movement of the terminal, which improves the accuracy of lens focusing and makes the captured scene clearer.
Description
technical field [0001] The present application relates to the technical field of lens control, and in particular, to a focus correction method and device. Background technique [0002] When shooting a scene through the terminal, in order to make the scene in the shooting scene clearer, it is necessary to focus on the scene in the scene through the camera. Therefore, it plays a vital role in the research of the camera focusing technology. [0003] In related technologies, when using the terminal to shoot, the terminal can control the movement of the driving motor through a preset algorithm, thereby controlling the movement of the lens in the terminal, and realizing the focus on the scene in the scene, so that the scene in the shot scene is clearer. [0004] However, during the movement of the driving motor, the movement of the lens cannot be accurately controlled by the driving motor due to the large vibration of the driving motor, so that the lens cannot be accurately focuse...
