1. An image decoding apparatus, comprising:
an intra-prediction unit configured to perform intra prediction on a first block, perform intra prediction on a second block adjacent to a right side of the first block, perform intra prediction on a third block adjacent to a bottom of the first block, and perform intra prediction on a fourth block adjacent to a right bottom of the first block,
wherein the first block, the second block, the third block, and the fourth block are predicted in one intra prediction mode,
wherein the first block, the second block, the third block, and the fourth block form a prediction block predicted in one intra prediction mode,
wherein the first block, the second block, the third block, and the fourth block are transform blocks on which intra prediction is performed,
wherein a size of the first block, a size of the second block, a size of the third block and a size of the fourth block are the same, and
wherein a width of the prediction block is equal to a height of the prediction block.
