Abstract: An image processing method includes obtaining a to-be-processed image; and obtaining a to-be-corrected line segment, through filtering based on at least one inertial measurement unit (IMU) information and a field of view that are included in metadata, from line segments included in the to-be-processed image. The to-be-processed image includes at least one of a vertical line segment and a horizontal line segment in a first scenario photographed by a photographing device. The method further includes correcting the to-be-corrected line segment and a feature region of the to-be-processed image to obtain a processed image, where the feature region includes a background region, a portrait region, and an edge region.

Abstract: An image transformation method includes obtaining a first image for a target scenario by using a front-facing camera, where the target scenario includes a face of a target person; obtaining a target distance between the face of the target person and the front-facing camera; and when the target distance is less than a preset threshold, performing first processing on the first image to obtain a second image. The first processing includes performing distortion correction on the first image based on the target distance. The face of the target person in the second image is closer to a real appearance of the face of the target person than the face of the target person in the first image.
