What is described are a method and a device, wherein two types of individual images are captured, namely a set of individual images captured simultaneously, and a further set of individual images captured in temporal succession. Among said two sets of individual images, individual images are selected which in combination result in a panoramic image.

Generating panoramic images

The fact that a beam-deflecting device can be produced cost-effectively and without any losses of optical quality of the multi-aperture imaging device is used when a carrier substrate is provided for the same, wherein the carrier substrate is common to the plurality of optical channels and is installed with a setting angle, i.e. oblique with respect to the image sensor in the multi-aperture imaging device such that a deflection angle of deflecting the optical path of each optical channel is based, on the one hand, on the setting angle and, on the other hand, on an individual inclination angle with respect to the carrier substrate of a reflecting facet of a surface of the beam-deflecting device facing the image sensor, the reflecting facet being allocated to the optical channel.

A multi-aperture imaging device includes at least one image sensor and an array of juxtaposed optical channels. Each optical channel includes optics for imaging of projecting at least one partial area of an object area on an image sensor area of the image sensor. A first optics of a first optical channel is configured to project a first partial area of the object area on a first image sensor area and to project a second partial area of the object area on a second image sensor area. A second optics of a second optical channel is configured to project at least a third partial area of the object area on a third image sensor area. The first partial area and the second partial area are disjoint in the object area. The third partial area overlaps incompletely with the first partial area.
