Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the existing virtual reality technology uses Fresnel lens or aspheric lens to enlarge the virtual image, When observing an object, if it does not depend on other hardware, it is difficult to feel the sense of spatial hierarchy between objects in the virtual space
That is, in the entire image, all areas are clear, which is contrary to the user's perception of the real environment, so that in virtual reality viewing, wrong judgments that are inconsistent with common sense are often made, and if a long time You will experience dizziness, eye irritation and other discomfort when watching movies

Abstract

The invention provides an optical element. The optical element comprises one or more optical lenses, wherein the one or more optical lenses form multiple first areas, at least two first areas in the multiple first areas have different focal lengths, so that a user sees pictures including clear areas and blurred areas in a viewing angle range when observing an image through the optical element, andthe pictures seen by the user have real space sense due to the clear areas and the blurred areas. The invention also discloses a visual imaging device and electronic equipment.

Description

technical field [0001] The present disclosure relates to an optical element, a visual imaging device and electronic equipment. Background technique [0002] With the development of science and technology, the use of virtual reality technology is gradually becoming popular, which enables users to immerse themselves in a virtual environment, thereby enriching people's lives. [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the existing virtual reality technology uses Fresnel lens or aspheric lens to enlarge the virtual image, When observing an object, if it does not rely on other hardware, it is difficult to feel the sense of spatial hierarchy between objects in the virtual space. That is, in the entire image, all areas are clear, which is contrary to the user's perception of the real environment, so that in virtual reality viewing, wrong judgments that are inconsistent with common ...
