Abstract
The present invention relates to image processing technologies, and discloses an image scaling method and apparatus to reduce distortion of a scaled image. The image scaling method includes: determining a distribution direction of main objects in a source image; and 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, where the nonlinear scaling method employs a scaling direction vertical to the distribution direction of the main objects in the source image. The embodiments of the present invention are primarily applicable to the image scaling field.
