AN APPRATUS FOR ESTIMATING A MOTION VECTOR FOR FRAME RATE CONVERSION AND A METHOD THEREOF

摘要

According to an embodiment of the present invention, a motion information estimating apparatus for converting a frame rate, comprises: an input unit in which image frames including first, second, and third frames are sequentially inputted; a first comparison unit for performing bi-directional interpolation by using the first and third frames together which are positioned at temporally bi-direction with respect to the second frame, and generating a first interpolation block to compare the same with an original block of the second frame; a second comparison unit for performing the interpolation by using only the first frame and generating a second interpolation block to compare the same with the original block of the second frame; a third comparison unit for performing the interpolation by using only the third frame and generating a third interpolation block to compare the same with the original block of the second frame; and a motion information generation unit for selecting an interpolation method having the most similarity based on a comparison result of the first, second, and third comparison units, and generating motion information corresponding to an interpolation target block based on the image frames and selected interpolation method.
