초록

In this paper we propose a new frame rate up conversion scheme which is used to overcome the motionblur problem of liquid crystal display caused by its slow response. The conventional bilateral motionestimation method which is mainly used in the frame rate up conversion scheme has a drawback thatit cannot find true motion vector if there are blocks with simple texture in the search range. To solvethis problem, a texture adaptive bilateral motion estimation method that increases cost value of blockwith simple texture is proposed. Also a motion estimation scheme that utilizes neighboring motion vectoreffectively is proposed to reduce computation time required to estimate motion. Since the proposed schemedoes not apply all available motion vectors within the search range, the execution time of frame rateup conversion can be reduced dramatically. Experimental results show that the interpolated frame imagequality of the proposed method is improved in subjective as well as objective view point compared withthat of the conventional method.
