Claim:
1. A motion picture encoding device comprising: an encoder to encode a motion picture signal composed of a plurality of fields with an inter-field motion compensating prediction, each field formed in a 4:2:0 picture format, the encoder encodes the motion picture signal according to at least one of a first calculation method, second calculation method, and third calculation method depending on parities of a reference field and a coding field so that a chroma motion vector is generated from a luminance motion vector and is in parallel with the luminance motion vector; the encoder including a switch that selects the first calculation method for encoding when both the reference and coding fields are a top field or both the reference and coding fields are a bottom field, selects the second calculation method for encoding when the reference field is the top field and the coding field is the bottom field, and selects the third calculation method for encoding when the reference field is the bottom field and the coding field is the top field.
