Abstract: The present disclosure discloses a photographing method and an apparatus in, relates to the photographing field and the field of image processing technologies. When multiple people take a group photo, no help from a third party is required. Therefore, implementation is convenient, and user satisfaction with a group photo result can be improved, thereby improving user experience. The method includes: obtaining a first image including an image of a first photographing background and a first to-be-photographed subject; then displaying a first preview interface, the first preview image includes an image of a second photographing background and an image of a second to-be-photographed subject, and a degree of coincidence between the image of the second photographing background and the image of the first photographing background is greater than or equal to a preset degree of coincidence; obtaining a target image based on the first image and the first preview image.

Abstract: An image processing method includes determining a target area and a background area in an image by performing mask segmentation on the image. Different color processing modes are applied to the target area and the background area, so that luminance of the target area is greater than luminance of the background area, or chrominance of the target area is greater than chrominance of the background area, and a main object corresponding to the target area is more prominently highlighted.

Abstract: An image processing method, where a target area and a background area are determined in an image by performing mask segmentation on the image. Different color processing modes are applied to the target area and the background area, such that luminance of the target area is greater than luminance of the background area, or chrominance of the target area is greater than chrominance of the background area, and a main object corresponding to the target area is more prominently highlighted. This enables a terminal user to have a movie special effect during photographing or video photographing, and improves photographing experience of the user. In addition, the present disclosure further provides a flicker elimination method, such that a color change of video content is smoother and more natural.
