Focusing correction method and device

Abstract

The invention provides a focusing correction method and device, and relates to the technical field of lens control. The focusing correction method comprises the steps that by controlling a driving motor to move towards a preset position, the forward definition, the forward position, the reverse definition and the reverse position are obtained, calculation is conducted according to the forward definition, the forward position, the reverse definition and the reverse position, and correction parameters are obtained; and finally, during the moving process of the driving motor, the moving distanceof the driving motor is corrected according to the correction parameters; through acquiring correction parameters, the moving distance of the driving motor is corrected according to the correction parameters; accurate focusing of a lens and accurate synchronous focusing can be realized in the zoom process of the lens; the problem that a shot scene is unclear due to the fact that a lens cannot be accurately focused in the prior art is avoided, errors generated when a driving motor moves are reduced, the driving motor can accurately control movement of a terminal, the lens focusing accuracy is improved, and therefore the shot scene is 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...
