Abstract
A method for displaying a video image includes acquiring foreground information about a video image to be output, where the foreground information includes information that defines a size of a foreground picture. The method further includes determining an adjustment coefficient for the foreground picture according to the size of the foreground picture, a size and a resolution of a display device, and a preset adjustment rule. The preset adjustment rule indicates that the product of the adjustment coefficient for the foreground picture and a zooming multiple for display on the display device is equal to a fixed constant. The method also includes adjusting the video image to be output according to the adjustment coefficient for the foreground picture, and outputting, to the display device for display, the video image after adjustment.
