    • 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 nth frame and an (n−1)th frame located adjacent the nth frame 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 nth frame with an MB of the (n−1)th frame, which may correspond to the MB of the nth frame, in order to separate each MB of the nth frame into a static object and a moving object. The MV estimation unit may search in the (n−1)th frame for an MB that matches with each of MBs of the nth frame, 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 nth frame, and the (n−1)th frame.
    • 提供了通过分离成静态对象和移动对象来执行运动估计的帧插值装置和方法。 帧内插装置按照顺序插入包括第n帧和第n + 1帧的第(n-1)个第帧的多个帧 以产生插值帧。 该装置的一些实施例包括静态对象分离单元,运动矢量(MV)估计单元和插值帧生成单元。 静态对象分离单元可以将第n帧的宏块(MB)与第(n-1)个第帧的MB进行比较,其可以对应于MB 的第n 帧的帧,以便将第n帧的每个MB分离成静态对象和移动对象。 MV估计单元可以在第(n-1)个第帧中搜索与第n 帧的每个MB匹配的MB,其可以被确定为 运动对象,估计一个MV。 内插帧生成单元可以使用估计的MV,第n个帧和第(n-1)个第帧生成内插帧。
