Abstract

The invention discloses an imaging adjustment apparatus and a method. The apparatus comprises an imaging analysis module, an imaging lens set and a lens adjustment module, wherein the imaging analysis module is used for determining whether present image of an object distorts relative to original image of the object and generating imaging correction information corresponding to distortion when the present image distorts, the imaging lens set is used for imaging the object and comprises a plurality of sub-areas capable of adjusting imaging parameters, the imaging adjustment module is used for adjusting the imaging parameters of the sub-areas corresponding to the imaging lens set based on the imaging correction information. The method and the apparatus provided by the invention image the object by imaging lenses capable of adjusting the imaging parameters in every sub-area, can individually carry out imaging parameter adjustment to every sub-area in order to carry out adjustment and correction to the perspective distortion of the object, avoid the image of the object obtained by a user generating the perspective distortion, so that user experience is raised.

Description

Technical field [0001] The present invention relates to the field of imaging technology, in particular to an imaging adjustment device and method. Background technique [0002] The Galilean telescope can form an erect virtual image 1030a of the observation object 1030 through a convex lens 1010 and a concave lens 1020 and change the angle between the virtual image and the eye, forming a visual effect of zooming in or pushing the observation object along the optical axis 1040. By adjusting the focal length of the two lenses and the distance between them, you can change the magnification and focus, such as Figure 12a-12c Shown. [0003] Lenses with a fixed focal length have been widely used in optical equipment such as glasses, telescopes, cameras, microscopes, etc. By combining lenses with different focal lengths and adjusting the distance between the lenses, the lens group can dynamically adjust the focal length. In addition, for example, the US patent applications with publicatio...
