Claim 6:
7. An intra prediction method, applied to a decoding apparatus and comprising:
deriving an intra prediction mode of a current block;
determining a pixel line for intra prediction of the current block among a plurality of pixel lines, wherein the pixel line is a reference pixel line;
performing filtering on a first reference pixel of the determined pixel line;
performing the intra prediction of the current block based on the intra prediction mode and the determined pixel line; and
performing correction on a prediction pixel of the current block according to the intra prediction mode;
wherein the filtering is selectively performed based on a first flag indicating whether the first reference pixel for intra prediction is filtered;
wherein the first flag is derived from the decoding apparatus based on a coding parameter of the current block, and
wherein the coding parameter comprises whether intra prediction in units of sub-blocks is applied.
