Light filtering structure, camera module and electronic equipment

Abstract

The invention discloses a light filtering structure, a camera module and electronic equipment. The light filtering structure comprises a light filtering container which comprises a light passing area; the light filtering structure further comprises a first light filtering assembly, a first light filtering medium is stored in the first light filtering assembly, and the first light filtering assembly is communicated with the light filtering container; the light filtering structure further comprises a second light filtering assembly, a second light filtering medium is stored in the second light filtering assembly, and the second light filtering assembly is communicated with the light filtering container; the first light filtering medium and the second light filtering medium are respectively used for filtering light of different wave bands; the light filtering structure has a first state and a second state; under the condition of the first state, the first light filtering medium is located in a light passing area; under the condition of the second state, the second light filtering medium is located in the light passing area.

Description

technical field [0001] The application belongs to the technical field of photography, and in particular relates to a light filtering structure, a photography module and electronic equipment. Background technique [0002] Usually, an infrared light filter can be set outside the image sensor (such as complementary metal oxide semiconductor (CMOS)) of the electronic device to filter the infrared light in the natural light, so that the electronic device can be imaged by the image sensor. At this time, the image sensor can obtain a clear image only based on other light (such as visible light to the human eye), so as to avoid the blurring of the captured image due to the different wavelengths of infrared light in natural light and visible light to the human eye. [0003] However, when electronic devices are used to take pictures in scenes where the intensity of visible light to the human eye is insufficient (such as night scenes or dark light scenes), after the infrared light is f...
