Provided in the present invention is a method for recovering a light field by means of time division by using a lens, the method comprising: arranging a lens in front of an image playback screen, the image playback screen comprising a multi-layer projection display screen, and a transparent medium that is filled between the projection display screen; the image playback screen acquiring spatial image information comprising depth information, and calculating the depth positions of all of the playback points of the spatial image in the image playback screen; by means of the multiple-layer projection display screen, cyclically playing back playback points having different spatial depth information respectively so as to be time-divided. Provided in the present invention is a method for recovering a light field by means of time division by using a lens, wherein spatial depth positions of an enlarged virtual image are changed by means of the multi-layer projection display screen of the image playback screen playing back playback points having different depth information so as to be time-divided, thereby achieving the goal of recovering the depth information of the image.
