Abstract

영상의 변환, 역변환 방법 및 장치가 개시된다. 본 발명에 따르면 NxN(N은 정수) 크기의 블록의 1차원 이산 코사인 변환에 이용되는 NxN 변환 행렬을 구성하는 원소들을 N개의 변수들에 기초한 값들로 치환하여 치환된 NxN 변환 행렬을 생성하고, 치환된 NxN 변환 행렬과 치환된 NxN 변환 행렬의 전치 행렬의 곱셈 행렬을 획득하며, 획득된 곱셈 행렬의 대각 성분을 제외한 나머지 원소들의 제곱합이 최소가 되도록 하는 N개의 변수들에 기초한 값들로 치환된 NxN 변환 행렬을 이용하여 NxN 크기의 블록을 변환하는 것을 특징으로 한다.
