Document Type and Number:
WIPO Patent Application WO/2023/088187
Kind Code:
A1
Abstract:
An ambient light sensor (100) and a data processing method thereof. The ambient light sensor (100) comprises: a light filtering structure (110) having a structural unit, wherein the light filtering structure is used for receiving ambient light having a color temperature to be recovered, and modulating the ambient light; a photodetector array (120), having a pixel unit mated with the structural unit, wherein the photodetector array is used for obtaining a light measurement value from the modulated ambient light; and a data processing unit (130), used for obtaining the spectrum data of the ambient light from the light measurement value, and using the spectrum data and the corresponding space information thereof to recover the color temperature data of the ambient light. Therefore, the ambient light can be modulated by means of the light filtering structure (110) having the structural unit, and the color temperature data of the ambient light is recovered on the basis of the spectrum data of the modulated ambient light, thereby obtaining the accurate color temperature data of the ambient light.
