摘要 |
An image coding apparatus which performs an adaptive coding process in macroblock units each comprising a predetermined number of pixels into which the image space is divided, comprises: a color motion vector coding unit for coding either a frame-basis color motion vector or a field-basis color motion vector of a target macroblock to be coded which is used in either the frame-by-frame motion compensation coding process or the field-by-field motion compensation coding process for an interlaced color signal, based on its prediction value; and a shape motion vector coding unit for coding a frame-basis shape motion vector of the target macroblock which is used in the frame-by-frame motion compensation coding process for an interlaced shape signal, based on a prediction value obtained from a color motion vector and a shape motion vector of a coded macroblock.
