This encoding method includes a derivation step and an encoding step. In the derivation step, on the basis of a fixed point degree of accuracy representing the roughness of a weight coefficient for motion compensation prediction of change in pixel values through multiplication by a reference image, a first standard value, which is a standard value for the weight coefficient, is derived. In the encoding step, a first differential value, which is the differential value of the weight coefficient and the first standard value, is encoded. The weight coefficient is included within a predetermined bit accuracy range centered approximately on the first standard value. |
