Claim:
1. A motion picture encoding device for making an inter-field motion compensation prediction and for executing an encoding process on a motion picture signal, wherein each frame has two fields and a number of pixels of a chrominance vertical component is different than a number of pixels of a luminance vertical component, the motion picture encoding device comprising: an encoder configured to generate a chrominance motion vector from a luminance motion vector based on an equation represented as when a reference field is a top field and a coding field is a bottom field, so that the generated chrominance motion vector and the luminance motion vector are thereby parallel, wherein MVy represents the luminance motion vector which indicates a vertical direction movement of a luminance pixel of a field image and MVCy represents the chrominance motion vector which indicates a vertical direction movement of a chrominance pixel of the field image.
