1. A decoding method, comprising:
deriving an intra prediction mode of a target block; and
generating a prediction block for the target block by performing intra prediction for the target block that uses the intra prediction mode, wherein:
the intra prediction for the target block is performed based on a horizontal reference pixel line and a vertical reference pixel line,
the horizontal reference pixel line is not adjacent to the target block,
the vertical reference pixel line is not adjacent to the target block,
a first prediction pixel of the prediction block is generated using at least one first reference pixel in the horizontal reference pixel line and the intra prediction mode for the target block, and
a second prediction pixel of the prediction block is generated using at least one second reference pixel in the vertical reference pixel line and the intra prediction mode for the target block.
