1. A decoding method, comprising:
determining a prediction mode for a target block; and
performing a prediction for the target block using a first reference pixel and a second reference pixel determined by the prediction mode,
wherein the first reference pixel and the second reference pixel are determined by a direction of the prediction mode,
wherein each of the first reference pixel and the second reference pixel is not adjacent to the target block,
wherein a X coordinate of the first reference pixel and a X coordinate of the second reference pixel are different from each other, and
wherein a Y coordinate of the first reference pixel and a Y coordinate of the second reference pixel are different from each other.
