Abstract
Provided are frame interpolation apparatus and methods in which motion estimation is performed by separation into a static object and a moving object. The frame interpolation apparatus interpolates multiple frames including an nframe and an (n−1)frame located adjacent the nframe in order to generate an interpolation frame. Some embodiments of the apparatus include a static object separation unit, a motion vector (MV) estimation unit, and an interpolation frame generation unit. The static object separation unit may compare a macroblock (MB) of the nframe with an MB of the (n−1)frame, which may correspond to the MB of the nframe, in order to separate each MB of the nframe into a static object and a moving object. The MV estimation unit may search in the (n−1)frame for an MB that matches with each of MBs of the nframe, which may be determined to be the moving object, to estimate an MV. The interpolation frame generation unit may generate the interpolation frame using the estimated MV, the nframe, and the (n−1)frame.
