| 摘要 |
The invention provides a method for performing intra-prediction. A target pixel is selected from a plurality of pixels of a current block. A first intra-prediction mode of a left block, a second intra-prediction mode of an up block, and a third intra-prediction mode of the current block are then determined. A first prediction value of the target pixel is calculated according to the first intra-prediction mode. A second prediction value of the target pixel is calculated according to the second intra-prediction mode. A third prediction value of the target pixel is calculated according to the third intra-prediction mode. The first prediction value, the second prediction value, and the third prediction value are then averaged to obtain a weighted-average prediction value as an intra-prediction value of the target pixel.
