Summary:The present invention relates to an image compression method and an image compression apparatus. According to a first aspect of the present invention, the method for compressing an image including an alpha-map comprises the steps of calculating a bounding box including all the pixels of the alpha-map that are not "0", and compressing the image by storing a region inside the bounding box of the image region. La présente invention concerne un procédé de compression d'image et un appareil de compression d'image. Selon un premier aspect de la présente invention, le procédé de compression d'une image incluant une carte alpha comprend les étapes consistant à calculer une boîte de délimitation comportant tous les pixels de la carte alpha qui ne sont pas égaux à « 0 », et à comprimer l'image en mémorisant une région à l'intérieur de la boîte de délimitation de la région d'image. 본 발명은 영상압축방법 및 영상압축장치에 관한 것이다. 본 발명의 제1측면에 따르면 알파맵을 포함하는 영상을 압축하기 위한 방법으로서, 상기 알파맵의 0이 아닌 픽셀을 모두 포함하는 바운딩박스를 연산하는 단계, 상기 영상 영역 중에서 상기 바운딩박스 내의 영역을 저장함으로써 상기 영상을 압축하는 단계를 포함하는 영상압축방법일 수 있다.
