1. A method for encoding an immersive image, the method comprising:
classifying each of multiple views into either a basic view or an additional view;
deriving patches from the additional view;
generating a current atlas based on the patches; and
encoding the current atlas,
wherein the current atlas is constituted of a valid region filled with valid pixels and an invalid region filled with invalid pixels,
wherein an overlapped region, that overlap with an invalid region of a reference atlas, within the invalid region of the current atlas is replaced by the invalid region of the reference atlas, and
wherein in response to the overlapped region of the current atlas is overlapped with two reference atlases, one of the two reference atlases that has a higher priority than the other is used to replace the overlapped region of the current atlas.
