1. A method of decoding an image, the method comprising:

  • obtaining a predicted direction of a luma component of a current block;

    obtaining a predicted direction of a chroma component corresponding to the predicted direction of the luma component according to one of predetermined decoding modes;

    obtaining a predicted block based on the predicted direction of the chroma component;

    obtaining a residue by decoding a bitstream; and

    restoring a current image by using the obtained predicted block and the obtained residue,wherein the predicted direction of the chroma component is identical to the predicted direction of the luma component.
