  "textContent": "An image processing device is disclosed that is able to accurately recognize objects at a close distance. The image processing device includes a camera unit (120), and an image processing unit (140). The camera unit includes a lens, a focusing unit that drives the lens to change a focusing distance of the camera unit, and an image pick-up unit. The focusing unit drives the lens to sequentially change the focusing distance of the camera unit to perform a focus-sweep operation, so that clear images of objects at different positions in an optical axis of the lens are sequentially formed on the image pick-up unit. The image pick-up unit sequentially picks up a plurality of images corresponding to different focusing distances in the focus-sweep operation. The image processing unit receives the plurality of images obtained by the image pick-up unit of the camera unit in the focus-sweep operation, identifies objects with clear images formed in the plurality of images, and produces an object distribution view according to the focusing distances used when picking up the plurality of image to show a position distribution of the identified objects. A moving body anti-collision device uses the object distribution view to determine whether the moving body is to collide with the identified object.",
