An apparatus for coding a moving picture in which one frame is comprised of two fields, includes a coder such that, with respect to all blocks in a frame, the odd field (the first field) and the even field (second field) are divided into blocks, thus permitting motion prediction of the second field from the first field, a coder means adapted for switching, every macro block, whether or not a frame is divided into the first field and the second field to generate block data to adaptively switch these coders every frame, thereby making it possible to obtain a picture of a high picture quality with a lesser quantity of information, to reduce the scale of hardware, and to reduce the capacity of a decoder.
