Or, in some embodiments, when the display area of the target object is preset, the display area of the target object is preset according to the proportion of the target object in the screen display area, so that after the image information is reduced or enlarged, the display scale in the screen display area meets the standard scale requirement. That is, the display area of the target object is determined based on the standard ratio of the target object in the screen display area and the target object. If the standard proportion of the target object in the screen display area is 1/2, determining the display area of the target object based on the target object and the standard proportion. Optionally, the standard occupation ratio of a single target object in the screen display area is different from the standard occupation ratios of multiple target objects in the screen display area, and optionally, the multiple target objects described in this embodiment refer to at least two target objects.
