Provided is an apparatus for generating an image, the apparatus including a processor configured to detect at least one object near a vehicle by using a result of sensing a surrounding area of the vehicle, determine a direction and a distance from the vehicle to the detected at least one object, and generate an image of the surrounding area of the vehicle based on the determined direction and distance. Therefore, the apparatus may accurately express a shape of the object and a relative location between the vehicle and the object on a three-dimensional (3D) image of the surrounding area of a vehicle.
