An electronic device includes a pixel layer, an image display control apparatus, a photosensitive layer, and a processor. The pixel layer includes a plurality of pixel units configured to display an image. The image display control apparatus is configured to control the plurality of pixel units to sequentially display at least one corresponding first image according to at least one first image signal. The photosensitive layer is configured to receive a reflected light formed after an emergent light emitted from the pixel layer when displaying one first image at each time is reflected by an object to be photographed, and to convert the reflected light received at each time into a second image signal. The processor is configured to determine an image of the object to be photographed according to the at least one first image signal and second image signals corresponding to the at least one first image signal.
