국제 표준화 기구 ISO/IEC JCT1/SC29/WG1 JPEG(Joint Photographic Experts Group)에서는 지난 30여년간 JPEG, JPEG 2000, JPEG XR, JPEG XT, JPEG XS 등 다양한 2D 이미지 압축 관련 표준을 제정해왔다. 지난 2014년 10월에는 JPEG Pleno라는 이름으로 2D 이미지가 아닌 3차원 영상 정보 압축을 위한 새로운 표준화 과제를 시작했다. JPEG Pleno에서 다루는 3차원 영상 정보는 라이트 필드, 포인트 클라우드, 홀로그램이다. 본 원고에서는 현재 JPEG Pleno 홀로그래피에서 다뤄지는 디지털 홀로그램 영상 압축에 대한 국제 표준화 현황을 소개하고, 향후 나아갈 방향을 전망해 본다.
