Abstract:
A motion vector derivation unit includes a comparison unit for comparing a parameter TR1 for a reference vector with a predetermined value to determine whether it exceeds the predetermined value or not; a switching unit for switching selection between the maximum value of a pre-stored parameter TR and the parameter TR1 according to the comparison result by the comparison unit; a multiplier parameter table (for multipliers); and a multiplier parameter table (for divisors) for associating the parameter TR1 with a value approximate to the inverse value (1/TR1) of this parameter TR1.
