Imaging device and method thereof

Abstract

Disclosed are an imaging device and method. The imaging device comprises: an imaging lens module (110) which is used for imaging at least one object (300a, 300b, 300c) and comprises a plurality of sub-regions with an adjustable imaging parameter; a position sensing module (120) which is used for obtaining position information about at least one object relative to the imaging device; an information processing module (130) which is used for determining an imaging parameter of a corresponding sub-region on the imaging lens module according to the position information about the at least one object relative to the imaging device; and a lens adjustment module (140) which is used for adjusting the imaging parameter of the corresponding sub-region of the imaging lens module according to the determined imaging parameter. Such an imaging device and method can simultaneously adjust imaging parameters which are respectively aimed at regions corresponding to a plurality of target objects at different distances in the field of view, so that a user can respectively view objects at different distances in the field of view in a relaxed and comfortable manner, thereby improving the user experience.

Description

technical field [0001] The present invention relates to the field of imaging technology, in particular to an imaging device and method. Background technique [0002] Wearable devices are gradually accepted by the public, such as Google glasses, smart watches, etc. These electronic smart devices will bring more convenience to people's lives. [0003] Traditional myopia or hyperopia glasses correct the refractive error caused by various reasons by adding a concave lens or a convex lens with a fixed focal length in front of the human eye with refractive error. However, traditional glasses are troublesome in optometry and glasses, and can only be corrected for a certain distance range. For objects beyond the certain distance, the user may not be able to obtain a clear image and feel blurred vision; or it may look very laborious and prone to eye fatigue. [0004] Based on the above situation, there have been multi-focal glasses with multiple focal lengths on one lens. Taking th...
