PROBLEM TO BE SOLVED: To achieve high encoding efficiency by improving prediction accuracy even when images with in a prediction block are specific nonlinear patterns or characters. ! SOLUTION: A intra-block copy prediction section 6, 35 performs an intra-block copy prediction processing on a prediction block Pin. After assuming pixel value of each pixel within a non-coded region in a maximum encoding block including a prediction block Pin using a predetermined method (after disposing pixels of a pixel value which is determined by a predetermined technique in the non-coded region), a reference block similar to the prediction block Pin is searched. !
