    摘要: An image decoding method decodes a coded stream which includes plural processing units and a header of the processing units, and which is generated by coding a moving picture using inter prediction, the processing units including at least one processing unit divided in a hierarchy, the hierarchy including: a highest hierarchical layer in which a coding unit exists as a largest processing unit; and a lower hierarchical layer in which a prediction unit exists. The method comprises: identifying, by parsing hierarchy depth information stored in the header and indicating a hierarchical layer higher than a lowest hierarchical layer in which a smallest prediction unit exits, a hierarchical layer which is indicated by the hierarchy depth information or a hierarchical layer higher than the indicated hierarchical layer, the hierarchical layer having a prediction unit in which a reference index is stored; and decoding the prediction unit, using the reference index.

    摘要: An image decoding method is provided for generating a predictive pixel value of a current picture to be decoded, and decoding the current picture using the predictive pixel value. The method includes a first parameter calculation step of calculating a first parameter corresponding to a distance between the current picture and a first reference picture; a second parameter calculation step of calculating a second parameter corresponding to a distance between the first reference picture and a second reference picture; a judgment step of judging whether or not a value of a third parameter calculated using a value obtained by dividing the first parameter by the second parameter is a value which is represented by a plurality of bits; a predictive pixel value generation step of generating a predictive pixel value of the current picture; and a decoding step of decoding the current picture using the predictive pixel value.
