METHOD AND APPARATUS FOR ENCODING IMAGE INFORMATION, AND METHOD AND APPARATUS FOR DECODING IMAGE INFORMATION |
| 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. |

1. An image information encoding method in which image information is compression-encoded by breaking an input image signal including a brightness signal and color-difference signal into blocks and making motion estimation and compensation of the input image signal in units of a block, the method comprising the step of:
shifting, 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. |
