Abstract: A method for obtaining a light source spectrum includes: obtaining first information in a current photographing scene, where the first information includes at least one of a first image generated by a red, green, and blue (RGB) sensor or a light intensity of light received by each pixel on a first multispectral sensor; inputting the first information into a first model to obtain a probability that a light source in the current photographing scene belongs to each type of light source; and determining a spectrum of the light source in the current photographing scene based on the probability that the light source in the current photographing scene belongs to each type of light source and a spectrum of each type of light source.

Abstract: Disclosed herein is a method for generating an image using an electronic device having a color camera, comprising: activating the color camera and a camera application on the electronic device; displaying, through the camera application, a preview image generated by the color camera; determining, automatically, whether the preview image includes an image of a first object; displaying, through the camera application in response to a determination that the preview image includes the image of the first object, a first image generated by the color camera, the first image including a color region corresponding to the first object and a grayscale region corresponding to objects that are not the first object; and displaying, through the camera application in response to a determine that the preview image does not include any image of the first object, a second image generated by the color camera, the second image is a grayscale image.
