In a moving picture encoding apparatus, a primary candidate reference motion vector-setting unit sets N primary candidate reference motion vectors. A degree of reliability calculation unit calculates the reliability of each primary candidate reference motion vector, which represents effectiveness in predicting a motion vector of a block to be decoded, using coded or decoded image information. A reference motion vector determination unit selects M (M<N) secondary candidate reference motion vectors in accordance with degree of reliability from among the N primary candidate reference motion vectors. A motion vector prediction unit creates a predictive motion vector of a block to be coded using M secondary candidate reference motion vectors with high reliability. |
