Patent number: 11765385Abstract: 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.Type: GrantFiled: May 4, 2022Date of Patent: September 19, 2023Assignee: LG ELECTRONICS INC.Inventors: Yong Joon Jeon, Seung Wook Park, Jae Hyun Lim, Jung Sun Kim, Joon Young Park, Young Hee Choi, Jae Won Sung, Byeong Moon Jeon
