Abstract:
An encoding apparatus having a direct mode as a prediction mode, when a pixel with opposite parity from a top field to a bottom field, for example, is referred to for obtaining a reference vector in the direct mode, performs correction by adding or subtracting a value corresponding to a half pixel to or from a value of the obtained reference vector. The encoding apparatus, when a pixel with opposite parity is referred to for obtaining a first and a second direct vector by temporally scaling the corrected reference vector, performs correction by adding or subtracting a value corresponding to a half pixel to or from values of the obtained direct vectors.
