A method for displaying an image is applied to an electronic device including a first camera and a second camera. The method includes: acquiring a first real-time image collected by the first camera and a second real-time image collected by the second camera, the first real-time image being different from the second real-time image; determining a target object in the first real-time image; generating a real-time virtual image corresponding to the target object; and displaying the real-time virtual image on the second real-time image.
