Claim One:
1. An image scaling method, comprising: determining a distribution direction of main objects comprising persons, faces of persons or areas of rich textures in a source image through detection of the source image; scaling the source image to a target image through a nonlinear scaling method according to the distribution direction of the main objects in the source image, wherein the nonlinear scaling method employs a scaling direction perpendicular to the distribution direction of the main objects in the source image, wherein the distribution direction is one of horizontal and vertical; wherein determining the distribution direction and scaling the source image are performed in a computer device; and wherein the determining the distribution direction of the main objects comprises: detecting the source image through face detection method, edge detection method, or entropy coding method; if the face detection method is performed, detecting the distribution of the faces of persons in the source image, obtaining the distribution direction of the main objects through the distribution direction of the persons and the symmetry information; if the edge detection method is performed, calculating the edge distribution of the source image, identifying the areas of rich textures in the source image, determining the distribution direction of the main objects; and if the entropy coding method is performed, detecting the direction with even distribution of the main objects in the source image, and determining the distribution of the main objects in the source image.
