Abstract: An image distortion correction method and an apparatus, where the method includes: performing optical distortion correction on a collected source image to obtain a first corrected image, where the first corrected image includes a background region and a portrait in which stretching deformation occurs, and where the portrait in which stretching deformation occurs includes at least a first human body region in which stretching deformation occurs and a second human body region in which stretching deformation occurs; and performing algorithm constraint correction on the first human body region, the second human body region, and the background region to obtain a second corrected image, where constraint terms used for the algorithm constraint correction respectively constrain the first human body region, the second human body region, and the background 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.
