The present invention relates to a method and an apparatus for generating a three-dimensional depth map by using a focus change. The apparatus for generating a three-dimensional depth map by using a focus change comprises: a power pattern generation part generating an inter-pixel change amount power pattern of a predetermined image property value according to a focus change for each unit block image for each of a plurality of focus change images generated by changing a focus for one image; and a depth map generation part generating a depth map for the image by using the power pattern. 본 발명은 초점 변화를 이용한 3D 깊이맵 생성 장치로, 하나의 영상에 대해 그 초점을 변화시켜 생성한 다수의 초점 변화 영상들 각각에 대해 단위 블록 영상별로 초점 변화에 따른 소정 영상 속성값의 픽셀 간 변화량 파워 패턴을 생성하는 파워 패턴 생성부와, 상기 파워 패턴을 이용하여 상기 영상에 대한 깊이맵을 생성하는 깊이맵 생성부를 포함한다.
