1. A video decoding method performed by a video decoding apparatus, the video decoding method comprising:
selecting at least one reference pixel line among a plurality of reference pixel lines, the plurality of reference pixel lines being located in the same image as a current block to be decoded using intra prediction;
deriving a predicted value of at least one pixel in the current block based on a value of at least one pixel included in the selected at least one reference pixel line; and
reconstructing the current block based on the predicted value,
wherein the deriving the predicted value is performed in units of subblocks in the current block.
