The video coding apparatus of the present invention for reducing pulsing artifacts includes: a correlation calculation unit which calculates a correlation value indicating a correlation degree of correlation between: a first block; and a second block or a third block. The first block including pixels included in a first original picture in an original picture sequence of original pictures, the second block including pixels included in a second original picture which precedes the first original picture, and the third block being obtained by coding and reconstructing the second block. The video coding apparatus includes a correlation judgment unit which judges whether the correlation value exceeds a first threshold, and judge that the correlation is high when the correlation value exceeds the first threshold; and a blending unit which blends the first block and the third block when the correlation judgment unit judges that the correlation is high.
