A moving picture coding is performed by adaptively switching between use of a plurality of decoded moving picture signals as reference frames to create a prediction macro block image from one of the plurality of reference frames for each macro block, isolation of a reference macro block from a plurality of reference frames to obtain an average value as a prediction macro block image, and isolation of a reference macro block from a plurality of reference frames to create a prediction macro block image by liner extrapolation or liner interpolation according to a frame-to-frame distance between the reference frames and the coding frame.
