Claim 0:
1. Device comprising:
a multi-aperture imaging device comprising:
an image sensor;
an array of adjacently arranged optical channels, each optical channel comprising optics for projecting at least a partial field of view of a total field of view on an image sensor area of the image sensor,
a beam deflector configured to deflect beam paths of said optical channels in different directions to obtain the total field of view,
focusing means for adjusting a focus position of said multi-aperture imaging device;

the device further comprising:
control means adapted to control the focusing means and to receive image information from the image sensor; wherein the control means is adapted to sequentially, one after the other, set a sequence of focus positions with the focusing means in the multi-aperture imaging device so as to detect a corresponding sequence of image information of the total field of view by capturing an image of the total field of view in each of the focus positions each uniformly set for the optical channels, and to create a depth map for the detected total field of view on a basis of the sequence of image information;
wherein the control means is adapted to
acquire, in the sequence of focus positions, a corresponding number of groups of partial images, each partial image being associated with an imaged partial field of view; to
produce, from a comparison of local image sharpness information in said partial images, depth maps and to produce therefrom said depth map; and
assemble, while using the depth map, the partial images of a group of partial images captured at a same focus position into a total image.
