Abstract: An apparatus and method for automatically generating panorama images is provided to facilitate the user operation. The apparatus comprises: a camera for rotating to a plurality of directions to shoot a corresponding partial image, and generating a panorama image according to the partial images; and a rotator for rotating the camera according to a control signal. The method comprises: generating two overlapping partial images; intercepting an image block from each partial image, wherein the image block contains an overlapping region of the partial images; performing edge detection on the image blocks; comparing the edge-detected image blocks to determine a range of the overlapping region; and assembling the partial images to generate the panorama image according to the range of the overlapping region.
