The primary objective of the present invention is the efficient performance of Golomb-Rice encoding. To achieve this objective, an encoding method comprises the steps of receiving image data for each predetermined unit, separately employing K types of k parameters to perform Golomb-Rice coding for the image data for each predetermined unit, and generating K types of Golomb-Rice coded data, holding the K types of Golomb-Rice coded data obtained at the generation step, based on the image data, selecting one of the k parameters for each predetermined unit, and employing the selected k parameter to select and output one of the K types of Golomb-Rice coded data that are being held.
