1. A method of decoding image, the method comprising:
performing entropy decoding of a bitstream to obtain entropy-decoded signals;
determining an intra prediction mode;
determining a scanning method based on the intra prediction mode; and
reconstructing a block using the entropy-decoded signals and the scanning method,
wherein the scanning method comprises:
performing a horizontal scan in response to the intra prediction mode being a vertical intra prediction mode; and
performing a vertical scan in response to the intra prediction mode being a horizonal intra prediction mode.
