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.
