A device includes a housing having a first transparent area and a second transparent area and a multi-aperture imaging device arranged inside the housing and including a beam deflector. The device includes a first diaphragm and a second diaphragm, the portable device having a first operating state and a second operating state. In the first operating state, the beam deflector deflects an optical path of the imaging device such that it passes through the first transparent area and that the second diaphragm at least partly optically closes the second transparent area. In the second operating state, the beam deflector deflects the optical path of the imaging device such that it passes through the second transparent area. In the second operating state, the first diaphragm at least partly optically closes the first transparent area.
