摘要：Provided is an encoding method for encoding a last position of a significant transformation coefficient in lossless coding, according to an exemplary embodiment, the encoding method including: performing scanning from a first point to a second point of a coding unit in a predetermined order to obtain a transformation coefficient included in the coding unit; determining a last position of a significant transformation coefficient that is not 0 from among transformation coefficients included in the coding unit; determining position information corresponding to the determined last position with respect to the second point; and encoding the determined position information.
