Abstract:
A motion prediction apparatus for predicting a motion in coding an input image, comprising:first motion estimating means for retrieving a previous image to perform motion estimating to predict a single-pixel motion vector in a top-to-top field path and in a bottom-to-bottom field path with respect to the input image; frame vector determining means for determining a frame motion vector on a basis of motion vectors outputted from the first motion estimating means; scaling means for scaling one of the top-to-top and the bottom-to-bottom single-pixel motion vectors received from the first motion estimating means to determine a single-pixel motion vector in a third field path; and second motion estimating means for retrieving a decoded image on a basis of each single-pixel motion vector outputted from the first motion estimating means, the frame vector determining means and the scaling means, wherein the third field path is at least one of a bottom-to-top field path and a top-to-bottom field path.
