An image anti-aliasing method and apparatus are provided, where the method includes acquiring a to-be-displayed image in a terminal, acquiring a current distance parameter of the terminal, where the current distance parameter is used to indicate a distance between an eye of a user of the terminal and a display screen of the terminal, determining a current anti-aliasing algorithm according to the current distance parameter by using a correspondence between a distance parameter and an anti-aliasing algorithm, and performing anti-aliasing processing on the to-be-displayed image according to the current anti-aliasing algorithm. In embodiments of the present disclosure, anti-aliasing processing is performed on a to-be-displayed image based on a distance parameter, that is, an anti-aliasing processing manner of the image is dynamically adjusted according to the distance parameter.
