摘要： An encoding circuit (1) encodes an input image. A thinning-out decision unit (2) determines whether or not a picture needs to be thinned out. A dummy picture storage device (4) stores a dummy picture. A dummy picture is encoded data in which all the blocks refer to the same picture, motion vectors of all the blocks are zero, and none of the blocks has prediction residual information. A reference picture selection unit (5) selects a reference picture from among a plurality of referenceable pictures. A header generating unit (7) generates a header to be added to a dummy picture. In the header, the selected reference picture is assigned to an index specifying a reference picture for the dummy picture.

摘要： When a prediction is made between fields with different parity, the predicative efficiency of a chrominance vector is improved by adaptively switching the generation of a chrominance motion vector depending on a encoding/decoding field parity (top/bottom) and a reference field parity (top/bottom), and the coding efficiency is improved accordingly.

摘要： 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.
