Disclosed are an apparatus and a method for generating an image for generation of a 3D panorama image. A method for generating a 3D panorama image in an image generating apparatus comprises the steps of: receiving an input of a plurality of 2D images and a plurality of depth maps corresponding to the plurality of 2D images; setting a left-eye image area and a right-eye image area for each of the plurality of 2D images on the basis of the plurality of depth maps; and synthesizing images of each of the left-eye image areas that are set in the plurality of 2D images to thereby generate a left-eye panorama image and synthesizing images of each of the right-eye image areas that are set in the plurality of 2D images to thereby generate a right-eye panorama image. Accordingly, the image generating apparatus can generate a 3D panorama image without distortion on the basis of a plurality of 2D images.
