A device comprising: an image sensor; an array of optical channels (16a-b), each optical channel (16a-b) including optics (64a-b) for projecting a partial field of view (72a-b) of a total field of view onto an image sensor area (24a-b) of the image sensor, a first optical channel of the array being configured to image a first partial field of view of the total field of view, and a second optical channel of the array being configured to image a second partial field of view of the total field of view; and a calculating unit configured to obtain image information of the first and second partial fields of view on the basis of the imaged partial fields of view (72a-b), and to obtain image information of the total field of view, and to combine the image information of the partial fields of view with the image information of the total field of view so as to generate combined image information of the total field of view; wherein the device is configured to obtain the image information of the total field of view having a first degree of scanning (b x c), to obtain the image information of the first or second partial field of view (72a-b) having a second degree of scanning (b x a), which is larger than the first degree of scanning (b x c), and to provide the combined image information of the total field of view having a third degree of scanning larger than the first degree of scanning; or wherein the calculating unit is configured to subdivide the image information of the total field of view and the image information of the partial fields of view into image blocks (63a, 63b) and to associate, block by block, image information (x, *, #), which is contained within a first image block of the total field of view, with matching image information of a second image block (63a, 63b) of the first or second partial fields of view so as to increase, by combining the first and second image blocks, a degree of scanning of the image information of the total field of view in the combined image information; wherein the calculating unit is configured to generate a depth map for the image information of the total field of view while using a first disparity between an image of the total field of view and an image of the first partial field of view and a second disparity between the image of the total field of view and an image of the second partial field of view. an image sensor; an array of optical channels (16a-b), each optical channel (16a-b) including optics (64a-b) for projecting a partial field of view (72a-b) of a total field of view onto an image sensor area (24a-b) of the image sensor, a first optical channel of the array being configured to image a first partial field of view of the total field of view, and a second optical channel of the array being configured to image a second partial field of view of the total field of view; and a calculating unit configured to obtain image information of the first and second partial fields of view on the basis of the imaged partial fields of view (72a-b), and to obtain image information of the total field of view, and to combine the image information of the partial fields of view with the image information of the total field of view so as to generate combined image information of the total field of view; wherein the device is configured to obtain the image information of the total field of view having a first degree of scanning (b x c), to obtain the image information of the first or second partial field of view (72a-b) having a second degree of scanning (b x a), which is larger than the first degree of scanning (b x c), and to provide the combined image information of the total field of view having a third degree of scanning larger than the first degree of scanning; or wherein the calculating unit is configured to subdivide the image information of the total field of view and the image information of the partial fields of view into image blocks (63a, 63b) and to associate, block by block, image information (x, *, #), which is contained within a first image block of the total field of view, with matching image information of a second image block (63a, 63b) of the first or second partial fields of view so as to increase, by combining the first and second image blocks, a degree of scanning of the image information of the total field of view in the combined image information; wherein the calculating unit is configured to generate a depth map for the image information of the total field of view while using a first disparity between an image of the total field of view and an image of the first partial field of view and a second disparity between the image of the total field of view and an image of the second partial field of view.
