Abstract

A multi-aperture imaging device includes an image sensor, an array of optical channels, each optical channel including an optic for imaging a partial field of view of a total field of view onto an image sensor region of the image sensor, and a beam-deflector switchable between a first rotational position and a second rotational position by executing a switching movement, and configured to deflect, in a first rotational position, optical paths of the optical channels into a first viewing direction, and to deflect, in a second rotational position, the optical paths of the optical channels into a second viewing direction. The array is configured to execute, based on the switching movement, an adjustment movement for adjusting an orientation of the array with respect to the beam-deflector.
