Provided are an apparatus and method for reducing the popping artifacts of level-of-detail terrain images. The apparatus includes a terrain patch constructor, a level-of-detail deciding unit, a controller, and a tapering unit. The terrain patch constructor forms terrain patches from multi-level level-of-detail patches. The level-of-detail deciding unit receives the generated terrain patches from the terrain patch constructor and decides a level-of-detail for each of the received terrain patches according to the camera distance. The controller determines whether adjacent terrain patches exist or not. The tapering unit receives terrain patches together with neighboring patches of adjacent level-of-detail from the level-of-detail deciding unit in response to the control of the controller and smoothly connects two terrain patches by applying the tapering technique.
