Abstract
This application provides a spherical image processing method which includes: obtaining a spherical image and determining a sphere center of the spherical image; determining a viewpoint of a user when the user views the spherical image, where the viewpoint is located at any point, other than the sphere center, in a sphere space surrounded by the spherical image; determining a pixel expansion region and a pixel shrinkage region on the spherical image based on the sphere center and the viewpoint; and performing an image processing operation on the spherical image, where the image processing operation comprises a pixel expansion processing operation on an image in the pixel expansion region, and a pixel shrinkage processing operation on an image in the pixel shrinkage region.
