Abstract: A method for determining light-source information, an electronic device, and a non-transitory storage medium are provided. The method includes acquiring a first infrared-band parameter under a current environment output by an image sensor, wherein the first infrared-band parameter is configured to represent a proportion of all infrared bands in the current environment to a full spectrum; and determining a light-source type and a light-source scenario of a light source in the current environment based on the first infrared-band parameter.
