Claim One:
1. An image processing device comprising: circuitry configured to operate as: a predictive motion vector generating unit that: sets a co-located vector to be not available in a candidate list as a condition that a type of a reference picture of a current block is different from a type of the reference picture of a co-located block included in a co-located picture; sets the co-located vector to be available and to be scaled in the candidate list as a condition that both the type of the reference picture of the current block and the type of the reference picture of the co-located block are short-term reference pictures; sets the co-located vector to be available and to be not scaled in the candidate list as a condition that both the type of the reference picture of the current block and the type of the reference picture of the co-located block are long-term reference pictures; and generates a predictive motion vector of a coding vector of the current block using the candidate list; and a reconstructing unit that reconstructs the coding vector by using the predictive motion vector generated by the predictive motion vector generating unit.
