1. An adaptive motion compensated interpolating method comprising: estimating motion vectors (MV) by performing block-based motion estimation (ME) between adjacent frames; calculating gradients of the estimated MVs; classifying pixels of each of the adjacent frames into a plurality of image regions according to the gradients of the estimated MVs; and determining pixel values to be obtained by interpolation between the adjacent frames by adaptively selecting pixels matched between the adjacent frames or the MVs estimated between the adjacent frames for each classified image region.
