Abstract:
A motion prediction apparatus, comprising:coding means connected to an input line for coding an input image;decoding means connected to the coding means for decoding the coded image signal; andfirst motion estimating means connected commonly to the input line and the decoding means for retrieving a motion in a single pixel unit repeatedly in accordance with a position information detected dependently at m layers with respect to the input image and for generating a second position information at the (m-1) numbered layer;second motion estimating means connected commonly to the decoding means and the first motion estimating means for estimating a motion in a single pixel unit with respect to a decoded reconstructed image at the m numbered layer in accordance with the second position information to generate a third position information, said m being an integer; andthird motion estimating means connected commonly to the second motion estimating means and the decoding means for estimating a motion in a half pixel unit with respect to the decoded reconstructed image at the m numbered layer in accordance with the third position information, wherein the decoded reconstructed image is loaded once and used by both the second and third motion estimating means.
