1. A method of decoding an image, comprising:
determining a prediction mode of a current chroma block as a mode that predicts the current chroma block from a luma block corresponding to the current chroma block;
obtaining a first prediction sample for the current chroma block based on the determination;
obtaining a second prediction sample for the current chroma block based on the determination;
obtaining a final prediction sample for the current chroma block based on the first prediction sample and the second prediction sample,
wherein the first prediction sample is predicted by using a non-directional (DC) mode, and
wherein the second prediction sample is obtained based on the luma block corresponding to the current chroma block.
