Image information encoding method and encoder, and image information decoding method and decoder |
摘要 |
In an image information encoder (10) supplied with an interlaced image in a 4:2:0 format, a color-difference signal phase correction unit (22) shifts, for motion estimation and compensation, the phase of the color-difference signal in a reference image block adaptively to a selected motion estimate mode and the value mv of vertical component in motion vector information so that the reference image block will coincide in phase of the color-difference signal with an input image block.
