PROBLEM TO BE SOLVED: To provide an image encoding device which carries out predictions from more various angles, thereby improving prediction efficiency.SOLUTION: A prediction set determining unit 13 selects a prediction set from a prediction set group including a plurality of prediction sets having different combinations of prediction modes corresponding to different prediction directions. Further, a prediction mode determining unit 11 selects a prediction mode from the selected prediction set. An entropy encoding unit 4 encodes the selected prediction set, the selected prediction mode, and residual data between a predicted image and an input image formed on the basis of the prediction set and the prediction mode. This allows the image encoding device to carry out predictions from more various angles, thereby improving prediction efficiency. |
