Abstract
Disclosed is a frame interpolating apparatus and a method thereof used at a frame rate conversion. The frame interpolating apparatus includes a calculation unit for performing a SAD Map calculation among inputted video signals with respect to a previous frame and a next frame and performing block matching, a determination unit for determining from the block-matched frame whether a video is repeated periodically and is changing fast, and an interpolation unit for selectively calculating a pixel value of an interpolated frame according to a determination result of the determination unit. Accordingly, the interpolated frame is vivid and clear, hence, removing the conventional blurring problem.
