A computer-implemented image processing method, comprising: displaying a first image, wherein the first image has a first size; receiving an operation of a user, wherein the operation of the user is any one of the following operations: a profile picture setting operation, a screen setting operation, a picture sharing operation, a contact list operation, and a picture sending operation; determining a salient object and a second circular region comprising the salient object in the first image, wherein a second diameter of the second circular region is greater than a first diameter of a first circular region, the second diameter is less than or equal to a shortest side length of the first image, and the first circular region is a smallest circular region comprising the salient object; cropping the first image based on the second circular region to obtain a second image; and displaying the second image, wherein the second image has a second size, the second size is less than the first size, and the second image comprises salient content on the first image; wherein the determining a second circular region comprising the salient object in the first image comprises: obtaining a first ratio of the first diameter to the shortest side length of the first image; if the first ratio is between a first threshold and a second threshold, determining the second circular region based on a preset ratio of the second diameter to the first diameter; and if the first ratio is less than the first threshold or greater than the second threshold, determining a square region in the first image, and determining an inscribed circle region of the square region as the second circular region, wherein the square region comprises the salient object, and a side length of the square region is the shortest side length of the first image. displaying a first image, wherein the first image has a first size; receiving an operation of a user, wherein the operation of the user is any one of the following operations: a profile picture setting operation, a screen setting operation, a picture sharing operation, a contact list operation, and a picture sending operation; determining a salient object and a second circular region comprising the salient object in the first image, wherein a second diameter of the second circular region is greater than a first diameter of a first circular region, the second diameter is less than or equal to a shortest side length of the first image, and the first circular region is a smallest circular region comprising the salient object; cropping the first image based on the second circular region to obtain a second image; and displaying the second image, wherein the second image has a second size, the second size is less than the first size, and the second image comprises salient content on the first image; wherein the determining a second circular region comprising the salient object in the first image comprises: obtaining a first ratio of the first diameter to the shortest side length of the first image; if the first ratio is between a first threshold and a second threshold, determining the second circular region based on a preset ratio of the second diameter to the first diameter; and if the first ratio is less than the first threshold or greater than the second threshold, determining a square region in the first image, and determining an inscribed circle region of the square region as the second circular region, wherein the square region comprises the salient object, and a side length of the square region is the shortest side length of the first image. obtaining a first ratio of the first diameter to the shortest side length of the first image; if the first ratio is between a first threshold and a second threshold, determining the second circular region based on a preset ratio of the second diameter to the first diameter; and if the first ratio is less than the first threshold or greater than the second threshold, determining a square region in the first image, and determining an inscribed circle region of the square region as the second circular region, wherein the square region comprises the salient object, and a side length of the square region is the shortest side length of the first image.
