Abstract:
1. A video coding apparatus for reducing pulsing artifacts, said video coding apparatus comprising: a correlation calculation unit calculating a correlation value indicating a degree of correlation between a first block and one of a second block and a third block, the first block including one or more pixels included in a first original picture in an original picture sequence of original pictures, the second block including one or more pixels included in a second original picture preceding the first original picture, and the third block being a reconstructed version of the second block obtained by coding and reconstructing the second block; a correlation judgment unit judging whether the correlation value exceeds a pre-determined first threshold, and judging that the correlation value is high when the correlation value exceeds the pre-determined first threshold; a blending unit blending the first block and the third block when said correlation judgment unit judges that the correlation value is high; and a coding unit (i) coding the first block of the first original picture when said correlation judgment unit judges that the correlation value is not high, and (ii) coding, as the first block of the first original picture, a block resulting from the blending performed by said blending unit when said correlation judgment unit judges that the correlation value is high.
