PROBLEM TO BE SOLVED: To provide a unique intra prediction process for improving efficiency of video coding.SOLUTION: H.264/AVC uses reference pixels in a horizontal boundary located immediately above a target block to be predicted and reference pixels in a vertical boundary located at the immediately left of the target block. In the present invention, at least some of pixels are picked-up from an array of horizontal boundary pixels and an array of vertical boundary pixels. Then, the picked-up pixels are added to the other boundary pixels to extend the array of the other boundary pixels. Intra prediction is performed, on the basis of only the extended array of the boundary pixels. |
