Abstract

A method for image processing includes the steps of: acquiring a first image including a foreground and a background, tracking a subject to be photographed in the foreground to determine a corresponding first foreground center offset and a corresponding first foreground pre-scaling ratio, performing a smooth processing on the first foreground pre-scaling ratio to obtain a first foreground quasi-scaling ratio, and outputting a second image based on the first foreground center offset and the first foreground quasi-scaling. A system and a non-transitory computer-readable storage medium for processing an image using the above method are also described.
