Image encoder and decoder using undirectional prediction |
摘要 |
The present invention relates to an image encoding and decoding technique, and more particularly, to an image encoder and decoder using unidirectional prediction. The image encoder includes a dividing unit to divide a macro block into a plurality of sub-blocks, a unidirectional application determining unit to determine whether an identical prediction mode is applied to each of the plurality of sub-blocks, and a prediction mode determining unit to determine a prediction mode with respect to each of the plurality of sub-blocks based on a determined result of the unidirectional application determining unit. |

1. An image decoding apparatus, comprising:
an intra-prediction unit for performing intra prediction on a first block, performing intra prediction on a second block adjacent to a right side of the first block, performing intra prediction on a third block adjacent to a bottom of the first block, and performing 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. |
