Abstract

The invention discloses an ambient light detection method, a detection device, a light detection assembly and electronic equipment, which relate to the technical field of optical sensors, in particular to the ambient light detection method applied to the electronic equipment. The electronic equipment comprises a light sensor and a light-transmitting assembly, the light-transmitting assembly comprises a first light filtering part and a second light filtering part, the first light filtering part is a set spectrum light filtering part, the second light filtering part is a color channel light filtering part. The ambient light detection method comprises the steps that a first light channel value and a second light channel value of a light signal collected by the light sensor are obtained, the first light channel value is a channel value of light passing through the first light filtering part, and the second light channel value is a channel value of light passing through the second light filtering part; a preset correction coefficient is obtained, wherein the preset correction coefficient is the ratio of the channel value of the light output by the noise light source to the second light channel value; and a third light channel value is determined according to a preset correction coefficient, the first light channel value and the second light channel value, and the third light channel value is the channel value of the ambient light.

Description

technical field [0001] The application belongs to the technical field of optical sensors, and in particular relates to an ambient light detection method, a detection device, a light detection component and electronic equipment. Background technique [0002] In related technologies, the screen dimming function of terminal devices such as mobile phones needs to rely on the collection of ambient light intensity, and dynamically adjust the display brightness of the screen according to the ambient light intensity. [0003] However, in the actual application process, the ambient light collected by the optical sensor will be affected by the light from light-emitting devices such as display screens, resulting in an inaccurate judgment of the environmental intensity by the optical sensor. [0004] Therefore, how to improve the accuracy of the optical sensor for detecting ambient light is an urgent technical problem to be solved. Contents of the invention [0005] The purpose of th...
