Title
(KO) 영상 처리 장치 및 그 영상 처리 방법
Abstract
(KO)
영상 처리 장치가 개시된다. 영상 처리 장치는, 입력부 및, 입력부를 통해 입력된 영상 프레임을 리타겟팅하여 출력 영상 프레임을 획득하는 프로세서를 포함하며, 프로세서는,출력 영상 프레임에 대한 정보 및 입력 영상 프레임에 기초하여 픽셀 값을 패딩할 영역을 식별하고, 식별된 영역에 포함된 대상 픽셀 영역을 기준으로 제1 픽셀 블럭을 식별하고, 제1 픽셀 블럭에 포함된 픽셀 값에 기초하여 제2 픽셀 블럭을 식별하고, 제2 픽셀 블럭에 포함된 픽셀 값에 기초하여 대상 픽셀 영역을 패딩하여 출력 영상 프레임을 획득할 수 있다.
