Abstract: In a night shot mode, a photo is captured and processed based on a plurality of frames. The plurality of frames is obtained based on a plurality of parameters including an exposure duration, a light sensitivity, and a number of frames. These parameters are determined based on factors, such as whether the electronic device is in a handheld state or not, and whether the current photographing scene is a dark scene or a light source scene.

Abstract: In an image processing method and apparatus of a terminal, the terminal includes a monochrome camera and a color camera. The monochrome camera and the color camera are disposed side by side. The method includes receiving a photographing instruction, and controlling, according to the photographing instruction, the monochrome camera and the color camera to simultaneously photograph a current scene, to obtain a monochrome image and a color image of the current scene. The method also includes obtaining a luminance component and a chrominance component of the color image. The method further includes fusing the luminance component with the monochrome image to obtain a luminance-fused component, and obtaining a target color image according to the luminance-fused component and the chrominance component. The monochrome image is fused with the color image.
