| titleOfInvention | Method and apparatus for coding moving image signal |
| abstract | According to a method and apparatus for coding a moving image signal, a change between a current frame and a previous frame is detected in units of blocks obtained by dividing a frame constituted by an input moving image signal into a plurality of pixels. A first valid block map is formed in units of frames by determining valid and invalid blocks on the basis of the detected changes. A first weighting operation of the formed first valid block map is performed. A second weighting operation of a fourth valid block map of the previous frame is performed. A weighted second valid block map is obtained by adding/synthesizing the first and fourth valid block maps respectively subjected to the first and second weighting operations. A third valid block map is obtained by performing predetermined segmentation of the second valid block map. A fourth valid block map is obtained by determining validity of an isolated invalid block in the third valid block map by referring to neighboring blocks. A valid block region of the fourth valid block map is coded. |
