Methods (700, 900) for providing information from an encoder (220) to a decoder (230) concerning a spatial validity range, at which view synthesis of an image at a virtual camera position can be performed with sufficient visual quality, based on a view of at least one real camera (210-1) comprised in a set of real cameras (210-1, 210-2, 210-3, 210-4). The methods (700, 900) comprises determining (701) the spatial validity range of the at least one real camera (210-1), which spatial validity range specifies for the decoder (230) what information to use for synthesising the image of the virtual camera position. Also, the determined (701) spatial validity range is transmitted (706) to the decoder (230). |
