Abstract

The invention is applicable to the technical field of light, and provides an environment brightness measuring method, an environment brightness measuring device and a mobile terminal. The environment brightness measuring device comprises a light sensor and a light taking window arranged above the light sensor, and also comprises a prism, wherein the prism covers the light taking window and converts environment light at the light taking window from incident light rays into vertical light rays. The environment brightness measuring device and the mobile terminal provided by the invention have the advantage that the environment brightness measurement accuracy can be improved.

Description

technical field [0001] The present disclosure relates to the field of light technology, and in particular, to a method, a device and a mobile terminal for measuring ambient brightness. Background technique [0002] Under different brightness environments of mobile phone screens, the relative brightness perception of the same actual brightness by the human eye is different. For example, a screen that looks normal indoors becomes very dark and hard to see in an outdoor bright light environment, and the screen of the mobile phone is very bright when turned on at night. In order to solve the above problems, all mobile phones are now equipped with light sensors. The light sensor is generally located above the main board of the mobile phone. There is a light-taking window at the corresponding position on the mobile phone screen. The light sensor can automatically adjust the brightness of the mobile phone screen according to the current light brightness of the mobile phone. , givi...
