Arrangements and methods therein for supporting view synthesis. One method is performed by an arrangement which is operable to receive an input video stream comprising an input view associated with a first camera position. The method includes receiving a measure M_D of a maximum difference in depth or disparity value between two pixels in a depth or disparity map representing the depth or disparity information of a video frame of the input view. The method further includes determining a maximal distance d_cam, from the first camera position to a second camera position, based on the received measure; and indicating the determined distance d_cam to a view synthesizer. This can enable the view synthesizer to synthesize a view associated with a second camera position so that disocclusions due to the distance between the first and second camera position may be handled.
