Abstract: This application provides an image display method and apparatus. The method includes: generating and displaying a first image based on first user operation information; storing the first image into a memory; when detecting second user operation information, determining, in the memory and based on the second user operation information, the first image corresponding to the second user operation information, where both the first user operation information and the second user operation information are used for displaying the first image; and displaying the first image. An image displayed for the first time is cached, so that when same user operation information triggers the image to be displayed again, a terminal device may directly capture, from a cache unit, an image that needs to be displayed, and does not need to draw the image before displaying the image.
