An electronic device including a projection unit; a memory to store at least one piece of projection information; and at least one processor. The at least one processor is configured to: identify a projection position and a projection angle corresponding to a projection surface position on which an image is to be output based on a user command; acquire correction information included in projection information corresponding to the projection surface position among the at least one piece of stored projection information; and move the projection position onto a region corresponding to the projection surface position that is corrected based on the correction information and control the projection unit to output the image which is acquired using keystone correction based on the region corresponding to the projection surface position corrected through the correction information.
