Abstract
An electronic device includes a light source, a lens group, a display screen, and a camera module. The light source emits a first light ray to an eyeball of a user, the first light ray is reflected by the eyeball and enters the camera module through the lens group, and a second light ray emitted by the display screen is partly reflected or transmitted into the camera module through the lens group. A control method includes controlling the display screen to display based on a display periodicity which includes display time periods and black insertion time periods that are alternately arranged; and controlling the camera module to perform exposure in the black insertion time period to obtain the first light ray, and to stop exposure in the display time period; and forming an eyeball image based on the first light ray.
