Abstract:
1. A frame interpolation apparatus that interpolates a plurality of frames including an n th frame and an (n−1) th frame located adjacent to the n th frame to generate an interpolation frame, the frame interpolation apparatus comprising: a static object separation unit that is configured to compare an n a motion vector (MV) estimation unit that is configured to search the (n−1) an interpolation frame generation unit that is configured to generate the interpolation frame using the estimated MVs, the n wherein the motion vector estimation unit searches in at least three search ranges of the (n−1)th frame and estimates at least three estimated MVs, and the interpolation frame generation unit selects a median value of the at least three estimated MVs for generating the interpolation frame and wherein the at least three search ranges includes a first search range, a second search range and a third search range, and the first search range includes the (n−1) wherein the MV estimation unit comprises: a search range processing unit that is configured to search in a first search range of the (n−1) a modified search range processing unit that is configured to search in a second search range of the (n−1) a current MB processing unit that is configured to match n wherein the first search range includes MBs of the (n−1) wherein the modified search range processing unit is configured to calculate a sum of absolute differences (SAD) for matching MBs and to estimate the second MV between an (n−1)
