Image display method and electronic equipment

The invention provides an image display method and electronic equipment, and relates to the technical field of terminals. According to the image display method, the difference value between the depth of the adjusted pixel point of the target object in the Nth frame of image and the depth of the corresponding pixel point on the target object in the (N-1) th frame of image is smaller than or equal to the first threshold value. Therefore, the depth difference between the pixel points on the target object of the Nth frame image and the pixel points on the target object of the (N-1) th frame image is small. The virtual object and the target object in the (N-1) th frame are shielded; the virtual object and the target object in the Nth frame of image are also shielded; under the condition that the depth difference between the pixel points on the target objects of the Nth frame image and the (N-1) th frame image is small, the shielding relation between the virtual object and the target object of ...
