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.

摘要： A encoding device includes a boundary pixel prediction value generation unit, boundary pixel prediction error estimation unit, and a quantized coefficient encoding unit. The boundary pixel prediction value generation unit generates a boundary pixel prediction value as a prediction value of a boundary pixel adjacent to an encoded block in the encoding block from a locally decoded image of a plurality of encoded blocks adjacent to the encoding block. The boundary pixel prediction error estimation unit generates boundary pixel prediction error estimation information from the boundary pixel prediction value and the encoding block prediction image with respect to the boundary pixel. The quantized coefficient encoding unit generates encoding block entropy encoded data from the quantized coefficients and the boundary pixel prediction error estimation information.

摘要： A welding control method alternately repeats a short circuit period, during which a welding wire and an object to be welded short-circuit, and an arc period, during which an arc is generated and discharged, to weld the object to be welded. The method compares average output voltage, which is an average of welding voltage calculated during welding, to set voltage preliminarily set, and controls a welding output current produced when an arc is generated based on the comparison result therefrom, to regulate the meltage of the wire for adjusting the arc length, which brings the short circuit cycle closer to a constant one when a disturbance (e.g. extended or shortened arc length) occurs.

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.
