Abstract: A method for setting the motion vector list and the apparatus using the same may include determining the presence of a first motion vector or a second motion vector by a sequential determination process in a first spatial candidate prediction group; and setting the first motion vector or the second motion vector produced through the sequential determination process as the candidate prediction motion vector. Thus, the encoding/decoding time and the complexity can be reduced by restricting the scaling number in a process for scanning the candidate prediction motion vector.

Abstract: Disclosed are an intra prediction method of a chrominance block using a luminance sample and an apparatus using the same. An image decoding method comprises the steps of: calculating an intra prediction mode of a chrominance block on the basis of an LM mapping table when the chrominance block uses an LM; and generating a prediction block for the chrominance block on the basis of the calculated intra prediction mode of the chrominance block. When intra prediction mode information of chrominance blocks are decoded, mutually different tables are used depending on whether or not an LM is used, so that encoding and decoding can be performed without an unnecessary waste of bits.
