TLDR
In this paper, an interpolation frame generating method performs motion detection processing using two blocks having different sizes, and adopts a motion vector detected by a smaller block under normal conditions.Abstract:
An interpolation frame generating method performs motion detection processing using two blocks having different sizes, and adopts a motion vector detected by a smaller block under normal conditions (Block 104). When a plurality of reliable motion vector candidates are detected in vector detection using the smaller block (YES of Block 103), a vector detected by a larger block is referred to (Block 105), and a motion vector which is closest to the motion vector detected with the larger block among the motion vectors detected with the smaller block is adopted as a motion vector of the block to be used for generating an interpolation frame (Block 106).read more
