Abstract

An imaging adjustment apparatus includes: an imaging analysis module, used to determine whether a current image of an object is deformed relative to an original image of the object, and when the current image is deformed, generate imaging correction information corresponding to the deformation; an imaging lens group, used to image the object, and including a plurality of subregions having adjustable imaging parameters; and a lens adjustment module, used to adjust an imaging parameter of a corresponding subregion of the imaging lens group according to the imaging correction information. An object can be imaged by using an imaging lens in which each subregion has adjustable imaging parameters, so as to adjust the imaging parameters for each subregion separately, thereby adjusting and correcting a perspective deformation that occurs on the object, preventing a perspective deformation from occurring on an image of the object acquired by a user, and improving user experience.
