Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes a motion estimation method for H.264 based on RDO(Rate-Distortion Optimization). RDO have not been adopted for motion estimation,because calculation of RD cost, which consists of accurate bits and distortion gotten from encoding and decoding, incursconsiderable computation cost. In the proposed method, high precision motion estimationwith practical computation cost can be attained by only applying RDO to sub-pixel motionestimation. In software simulation results for several video sequence, the proposed method can achieve about 1.71\%～3.11\% bit reduction in compared withconventional SAD based approaches.
