Imaging device and method

Abstract

The invention discloses an imaging device and an imaging system. The imaging device comprises an imaging lens module, an information processing module and a lens adjusting module, wherein the imaging parameter of the imaging lens module is adjustable; the imaging lens module is used for imaging an observation object of an imaging receiving party; the information processing module is used for detecting the focusing point position of the imaging receiving party and determining the imaging parameter of the imaging lens module according to the focusing position; and the lens adjusting module is used for adjusting the image lens module according to the determined imaging parameter. According to the device and the method of the embodiment of the invention, the focusing point position of the imaging receiving party can be automatically detected, and the imaging parameter of the imaging lens module positioned between the imaging receiving party and the object can be automatically adjusted according to the focusing point position, so that the imaging receiving party (such as eyes of a user) can obtain clear images of the objects at different distances conveniently.

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...
