A motion estimation device configured to estimate motion for blocks included in an input picture using a reference picture includes an internal reference memory configured to store the reference picture transferred from outside the motion estimation device; a motion estimator configured to estimate motion information for a target block that is a block of the input picture and where motion is to be estimated, using pixel data of the reference picture stored in the internal reference memory; a motion compensator configured to perform motion compensation for the target block using the motion information estimated by the motion estimator; and a reference memory manager configured to control the internal reference memory. The reference memory manager is configured to control the internal reference memory to store a luminance reference picture and a color-difference reference picture as the reference picture. |
