1. A method for photographing a panoramic image in a portable terminal, the method comprising the steps of: detecting Motion Vectors (MVs) of a plurality of images captured through a photographing unit; selecting a first region to be included in a left-view image and a second region to be included in a right-view image, from each of the plurality of images, based on the MVs; generating the left-view image including each of the selected first regions; generating the right-view image including each of the selected second regions; and generating a three-dimensional (3D) panoramic image including the left-view image and the right-view image, wherein selecting the first region and the second region from each of the plurality of images comprises: selecting a previous first region from a previous image and a current first region from a current image, based on a first reference line; and selecting a previous second region from the previous image and a current second region from the current image, based on a second reference line, and wherein the first reference line and the second reference line are standards for generation of a 3D image.
