Abstract:
1. A method for determining a motion vector of one interpolated image block in an interpolated image frame in a sequenced order of image frames, wherein the interpolated image frame is generated according to a first image frame and a second image frame, in succession, and the first and second image frames are partitioned into a plurality of first image blocks of a first image block size and a plurality of second image blocks of a second image block size, wherein the first image block size is larger than the second image block size, the method comprising: performing block matching for a first image block between the first image frame and the second image frame to generate a first candidate motion vector locating the interpolated image block in the interpolated image frame, the first image block being of the first block size; performing block matching for a second image block between the first image frame and the second image frame to generate a second candidate motion vector locating the interpolated block in the interpolated image frame, the second image block being of the second image block size; and selecting one of the first candidate motion vector and the second candidate motion vector as a target motion vector locating the interpolated image block in the interpolated image frame, wherein selecting the target motion vector of the interpolated image block comprises:
