| 1. An image encoding method using residue prediction of an image, which encodes an original image including at least more
than two components, the method comprising:
obtaining a residue corresponding to a difference between the original image and a prediction image with respect to each component
of the original image;
encoding the residue of a predetermined component of the original image;
restoring the encoded residue of the predetermined component and transforming the restored residue into a predetermined value
including the restored residue value; and
encoding prediction residues corresponding to differences between each of residues of components of the original image, which
are not encoded, and the residue, which is restored and transformed into the predetermined value.
