Claim Text:
1. A video encoding apparatus comprising: a reference vector deriving unit to derive as a reference vector a vector used when encoding a block that is near a block to be encoded and is included in a region where a field picture to be encoded is subjected to encode; a scaling unit to scale the reference vector based on a temporal distance between the field picture to be encoded and a first encoded field picture specified by the reference vector and a temporal distance between the field picture to be encoded and a second encoded field picture specified by a reference index and referenced by the block to be encoded in the field picture to be encoded to generate a motion prediction vector; and a motion prediction vector correction unit to correct the motion prediction vector using a parity of the field picture to be encoded, a parity of the first encoded field picture, and a parity of the second encoded field picture to generate a corrected motion prediction vector, wherein, when a display time of the field picture to be encoded is Curr poc, a display time of the first encoded field picture specified by the reference vector is ref the motion prediction vector correction unit corrects the motion prediction vector MVp′ using a isBottomFieldCurr flag indicating that the field picture to be encoded is a Bottom Field, a isBottomFieldRef
