摘要： The picture coding method of the present invention is a picture coding method for coding a picture on a block-by-block basis, comprising: a selection step of selecting one of at least two sizes as a size of a block on which orthogonal transformation should be performed; a transformation step of performing orthogonal transformation on a block having the selected size; a coding step of coding data of said block obtained in the transformation step; and a generation step of generating a coded stream that includes the coded data of the block and size information concerning the size selected in the selection step, wherein the size information indicates whether or not the size is a fixed block size within a predetermined section in the coded stream, and the predetermined section is one of a sequence, a group of pictures, a picture, a slice, and a macroblock.
