<p>An image capturing device (1) is disclosed comprising an electronic image detector (17) having a detecting surface (15) , an optical projection system (5) for projecting an object within a field of view onto the detecting surface (15) , and, optionally, a computing unit (19) for manipulating electronic information obtained from the image detector (17) , wherein, the projection system (5) is adapted to project the object in a distorted way such that, when compared with a standard lens system, the projected image is expanded in a center region of the field of view and is compressed in a border region of the field of view. Preferably, the projection system (5) is adapted such that its point spread function in the border region of the field of view has a full width at half maximum corresponding essentially to the size of corresponding pixels of the image detector (17) .</p> |
