Problems solved by technology
[0003] Optical anti-shake modules, especially translational closed-loop optical anti-shake modules, have high assembly requirements. However, due to inconsistent assembly in module factories, there will be problems with inconsistent maximum movement ranges of the same type of optical anti-shake modules. Thus affecting the scope of use of the optical image stabilization module and reducing the anti-shake effect of the optical image stabilization module

The invention is applicable to the technical field of shooting equipment, and provides a detection method of an optical anti-shake module, a mobile terminal and a computer readable storage medium. Thedetection method comprises the following steps: acquiring an image of a target object fixed at a second preset position through a camera, in which the optical anti-shake module is located, at a firstpreset position, wherein during acquisition of the image, an image acquired by a suspension lens in the optical anti-shake module at the center position of a moving space is used as a reference image, and an image acquired by the suspension lens in the optical anti-shake module at a position, farthest to the center position, in N directions of the moving space is used as a maximum migration imagecorresponding to the decibel of each direction; and acquiring maximum moving distances, respectively corresponding to the N directions, of the suspension lens according to the reference image and themaximum migration images respectively corresponding to the N directions. According to the detection method of the optical anti-shake module, the anti-shake effect of the optical anti-shake module canbe enhanced.
Description
technical field [0001] The application belongs to the technical field of photographing equipment, and in particular relates to a detection method of an optical anti-shake module, a mobile terminal and a computer-readable storage medium. Background technique [0002] Optical image stabilization uses movable components to compensate for the shifted optical path when the camera shakes, thereby achieving the effect of reducing photo blur. Most of the current cameras have added an optical anti-shake module to overcome image blur caused by camera vibration. [0003] Optical anti-shake modules, especially translational closed-loop optical anti-shake modules, have relatively high assembly requirements. However, due to inconsistencies in the assembly of the module factory, there will be a problem that the maximum movement range of the same type of optical anti-shake modules is inconsistent. As a result, the scope of use of the optical image stabilization module is affected, and the ...
