Method and device for determining regulation area and method and device for regulating light transmissivity

Abstract

The embodiment of the invention discloses a method and device for determining the regulation area and a method and device for regulating the light transmissivity, and belongs to the field of electronic equipment. The methods and devices are used for regulating the light transmissivity of only the perpendicular incidence part of strong light but not the non-perpendicular incidence part of the strong light, then perpendicular incidence on the eyes of a user from the strong light can be weakened, the eyes of the user can be protected, meanwhile, the user can see other areas in a view field clearly through the non-perpendicular incidence part of the strong light, and the user experience can be improved. The method for determining the regulation area comprises the specific steps of acquiring light source distance information, and determining the regulation area of a regulation unit according to the light source distance information and first information acquired in advance.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a method and device for determining an adjustment area and adjusting light transmittance. Background technique [0002] Nowadays, with the continuous development of science and technology, there are more and more strong lights in people's living environment, such as computers, mobile phones, tunnel lights, viaduct lights, etc. It has been proved by medicine that when strong light shines on the human eye, the pupil of the human eye will automatically shrink to control the light entering the eye, and long-term pupil shrinkage will cause eye muscle spasm and fatigue, and long-term strong light incidence will also affect the Some degree of damage to the retina of the human eye. [0003] In the prior art, glasses are usually used to shield the eyes from strong light. The spectacle lenses of such glasses are made of color-changing glass. This color-changing glass material makes the...

Problems solved by technology

However, the transmittance of the non-direct part of the strong light of the glasses is also weakened, so that the light intensity of the non-direct part of the strong light entering the user's eyes is reduced, causing the user to see clearly the area with low light intensity in the field of vision. degraded user experience

And if the user is driving at a high speed or on the highway at this time, the user will not be able to see all the scenery in the field of vision due to strong light, which will put the user in danger
