<p>PROBLEM TO BE SOLVED: To provide an image encoding device capable of reducing a code amount for designating a prediction parameter without sacrificing coding efficiency.SOLUTION: The image encoding device includes; a first prediction parameter determination unit (53) which selects, from a basic set, prediction parameters for each prediction unit belonging to a first group; a second prediction parameter determination unit (55) which selects prediction parameters for each prediction unit belonging to a second group from a reduced set that comprises prediction parameters equal to or fewer than the number of the prediction parameters included in the basic set and that includes at least some of the prediction parameters selected by the first prediction parameter determination unit (53); and a prediction parameter encoding unit (243) which encodes which of the prediction parameters the first prediction parameter determination unit (53) has selected and which of the prediction parameters the second prediction parameter determination unit (55) has selected.</p> |
