A provision of high quality panoramic or semi-panoramic 3D scenes is achieved at reasonable efforts by arranging the plurality of camera pairs, each of which is associated with a respective one of mirror plane surfaces of a pyramid or clipped-pyramid shaped mirror in that same is directed towards the respective associated mirror plane surface, such that for each camera pair the virtual positions of pivot points of the cameras of the respective camera pair are offset from each other along a straight baseline which, in turn, is offset from the axis of the mirror, and a distance between virtual points of a left-hand channel camera of a first camera pair associated with a first mirror plane surface and a right-hand channel camera of a second camera pair associated with a second mirror plane surface positioned neighboring the first mirror plane surface, deviates from a length of the baselines of the camera pairs by less than 10% of the length of the baselines.
