Problems solved by technology

Therefore, the global uniform zoom will cause the user's overall field of view to change, and in many scenarios (for example, AR (Augmented Reality, augmented reality) environment) will bring discomfort to the user and make it inconvenient to use

Embodiment Construction

[0130] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0131] In many application scenarios, the user only wants to locally zoom the observed object while maintaining the sense of distance in the surrounding environment. For example, when the user is driving, he hopes to carefully observe the license plate number of the vehicle far ahead, and at the same time, he does not want to ignore the road. other vehicles on the road (it may be dangerous if you ignore it), it is not appropriate to use a uniform zoom method to change the user's overall field of vision at this time. Therefore, this embodiment provides a local zoom imaging method, when using the method described in this embodiment to Figure 1a When the object B in the user's ...

Abstract

The invention provides a method and a device for local zoom imaging, and relates to the field of imaging. The method comprises the steps of determining a gazing object of the eyes; determining a corresponding sub-area of an imaging lens group according to the gazing object, wherein the imaging lens group is used for carrying out zoom imaging on the gazing object and comprises a plurality of sub-areas whose zooming characteristics are adjustable; and determining zooming parameters of the corresponding sub-area according to the gazing object. The method and the device provided by the invention can zoom imaging of the gazing object on the eye fundus of a user in a local zoom mode, thereby avoiding changes in overall visual field of the user, enabling the user to observe the gazing object conveniently, and being capable of have a correct perception of the surrounding environment at the same time.

Description

technical field [0001] The present invention relates to the field of imaging technology, in particular to a local scaling imaging method and device. Background technique [0002] For users with healthy eyes, it is difficult for the eyes to observe the desired details when the viewing object is small or far away. For example, when people sit at a far position to watch a football game, it is difficult to observe the details of the players' body movements and expressions. For users with problems such as nearsightedness or farsightedness in their eyes, it is more difficult for the eyes to recognize the details of the observed object or person when the viewing object is small or remote. Conversely, when the viewing object is too large or too close, it is difficult for the user to observe the global information of the viewing object. For example, when a user is standing in front of a tall building or a mountain, it is difficult to observe their overall situation. [0003] Tradi...
