An image pickup device which can obtain an image of wide range picked up by a plurality of cameras is provided by preventing occurrence of parallax.The image pickup device is constructed such that an object of wide range is divided into a plurality of divided object portions to be separately picked up by a plurality of image pickup elements and images of divided object portions are processed into one combined video image by a processing element to which information on video images supplied from the respective image pickup elements is input; the image pickup element includes a lens 21 and an image pickup element 23 which detects rays of light passed through the lens 21, and when principal rays positioned in a Gauss area are selected from among the principal rays passing through the center of an aperture stop 22 of the lens 21 in the image pickup element and a point where linear components of the selected principal rays in an object side space are extended to intersect an optical axis is defined as an NP point 26, in respective image pickup elements a position of the NP point 26 is set behind the image pickup element 23 and respective NP points of the plurality of image pickup elements are made to congregate within a predetermined radius area in which one NP point 26 is centered.
