1. A multilevel selective rendering method for increasing rendering performance, comprising:
setting a multilevel threshold for a current tile in a rendering process for an image frame divided into a plurality of tiles;
generating initial sampling blocks by performing initial sampling for the current tile;
generating first level blocks by performing first level selective rendering according to a first level threshold of the multilevel threshold based on the initial sampling blocks;
generating second level blocks by performing second level selective rendering according to a second level threshold of the multilevel threshold based on the first level blocks; and
initiating the multilevel selective rendering for a next tile of the current tile when multilevel selective rendering for the current tile is completed through repetition of level-specific selective renderings.
