Abstract
A method for an intra predicting process of a video block is provided. The method comprises: obtaining a predicted sample value for a sample of the current coding block; obtaining a scaling factor value according to an intra prediction mode for the current coding block, and according to a height of the current coding block and/or a width of the current coding block; determining a first weight based on the scaling factor value; determining a second weight based on the scaling factor value; calculating an additional value as a weighted sum of a top reference sample value and a left reference sample value, by weighting the top reference sample value with the first weight and weighting the left reference sample value with the second weight; obtaining a modified predicted sample value according to the additional value and the predicted sample value; and outputting the modified predicted sample.
