To provide a moving picture decoding device capable of continuing motion compensation even when an error is included in a filter coefficient for motion compensation. The moving picture decoding device includes: a decoding unit (1001) which decodes (i) a motion vector indicating a sub-pixel position and (ii) a filter coefficient for identifying a pixel value at the sub-pixel position, the motion vector and the filter coefficient being included in a coded stream; an error detecting unit (1002) which detects an error in the filter coefficient; a modifying unit (1010) which modifies one of the motion vector and the filter coefficient so as to enable identification of a pixel value at a pixel position for motion compensation, when the error is detected; and a motion compensation unit (1007) which performs motion compensation by identifying the pixel value at the pixel position using the modified one, when the error is detected.
